Risk-adjusted capitation based on the Diagnostic Cost Group Model: an empirical evaluation with health survey information. (1/526)

OBJECTIVE: To evaluate the predictive accuracy of the Diagnostic Cost Group (DCG) model using health survey information. DATA SOURCES/STUDY SETTING: Longitudinal data collected for a sample of members of a Dutch sickness fund. In the Netherlands the sickness funds provide compulsory health insurance coverage for the 60 percent of the population in the lowest income brackets. STUDY DESIGN: A demographic model and DCG capitation models are estimated by means of ordinary least squares, with an individual's annual healthcare expenditures in 1994 as the dependent variable. For subgroups based on health survey information, costs predicted by the models are compared with actual costs. Using stepwise regression procedures a subset of relevant survey variables that could improve the predictive accuracy of the three-year DCG model was identified. Capitation models were extended with these variables. DATA COLLECTION/EXTRACTION METHODS: For the empirical analysis, panel data of sickness fund members were used that contained demographic information, annual healthcare expenditures, and diagnostic information from hospitalizations for each member. In 1993, a mailed health survey was conducted among a random sample of 15,000 persons in the panel data set, with a 70 percent response rate. PRINCIPAL FINDINGS: The predictive accuracy of the demographic model improves when it is extended with diagnostic information from prior hospitalizations (DCGs). A subset of survey variables further improves the predictive accuracy of the DCG capitation models. The predictable profits and losses based on survey information for the DCG models are smaller than for the demographic model. Most persons with predictable losses based on health survey information were not hospitalized in the preceding year. CONCLUSIONS: The use of diagnostic information from prior hospitalizations is a promising option for improving the demographic capitation payment formula. This study suggests that diagnostic information from outpatient utilization is complementary to DCGs in predicting future costs.  (+info)

Welfare gains from user charges for government health services. (2/526)

The World Bank's Financing health services in developing countries emphasizes demand-side issues--highlighting user fees, insurance, and the private sector as tools for strengthening the health sector. That approach is a major departure from the focus on the supply side--public sector spending, costs, management, and efficiency--that has dominated the international health finance agenda for many years. An important set of empirical papers by Paul Gertler and his co-authors coincided with the release of the policy paper. Gertler's work has questioned a policy of greater dependence on user fees by emphasizing the potential welfare costs to consumers of higher fees for medical services. Many health professionals have adopted the jargon of this new approach without understanding the underlying analysis. This article attempts to demystify the debate that has ensued by illustrating economists' idiosyncratic approach to welfare, explaining how the policy paper and Gertler differ, and suggesting alternative approaches to testing the feasibility of the policy paper's prescriptions.  (+info)

The influence of day of life in predicting the inpatient costs for providing care to very low birth weight infants. (3/526)

The purpose of this study was to test, refine, and extend a statistical model that adjusts neonatal intensive care costs for a very low birth weight infant's day of life and birth weight category. Subjects were 62 infants with birth weights below 1,501 g who were born and cared for in a university hospital until discharged home alive. Subjects were stratified into 250-g birth weight categories. Clinical and actual daily room and ancillary-resource costs for each day of care of each infant were tabulated. Data were analyzed by using a nonlinear regression procedure specifying two separate for modeling. The modeling was performed with data sets that both included and excluded room costs. The former set of data were used for generating a model applicable for comparing interhospital performances and the latter for comparing interphysician performances. The results confirm the existence of a strong statistical relationship between an infant's day of life and both total hospital costs and the isolated costs for ancillary-resource alone (P < 0.0001). A refined series of statistical models have been generated that are applicable to the assessment of either interhospital or interphysician costs associated with providing inpatient care to very low birth weight infants.  (+info)

Pharmacoeconomic analysis of selected antibiotics in lower respiratory tract infection. (4/526)

An interactive pharmacoeconomic model was designed to evaluate the effects of clinical response and adverse drug events on the comparative cost and cost-effectiveness of a relatively new antibiotic, clarithromycin, compared with those of six other antibiotics used to treat community-acquired lower respiratory tract infection. The cost and cost-effectiveness analyses were based don 12 randomized, double-blind, controlled clinical trials conducted between 1987 and 1992 in regionally distributed outpatient clinics in the United States. The trials enrolled a total of 2377 patients. Of the 2377, 1102 patients were treated for acute exacerbation of chronic bronchitis, 591 for pneumonia, and 201 for either of the two conditions. Safety data for one of the antibiotics was obtained from a trial of patients with sinusitis (N = 483). The antibiotics included in the analysis were amoxicillin/clavulanate, ampicillin, cefaclor, cefixime, cefuroxime, clarithromycin, and erythromycin. The main outcome measures were the costs of resources to achieve a clinical response, costs related to managing adverse drug events, and costs of antibiotic treatment from the perspective of managed care. The mean total cost per episode ranged from approximately $137 to $267. The drug acquisition cost typically contributed a small amount to the overall cost. For the cost-effectiveness analysis, in which complication-free cure was used as a proxy for patient satisfaction, the range of mean cost per complication-free cure varied from approximately $307 for clarithromycin to $612 for cefaclor. When ranked from most to least cost-effective, the order was as follows: clarithromycin, cefixime, amoxicillin/clavulanate, erythromycin, cefuroxime, ampicillin, and cefaclor. The costs associated with clinical management (including treatment failure) and managing adverse drug events significantly contribute to the total cost and cost-effectiveness of antibiotics in the outpatient setting. Cost-effectiveness analyses are valuable in analyzing the various costs associated with the treatment of lower respiratory tract infection (acute exacerbation of chronic bronchitis or pneumonia) and may be useful tools for physicians managing patients, members of pharmacy and therapeutics committees developing formularies, and medical staff implementing practice guidelines.  (+info)

Prevention of nonsteroidal anti-inflammatory drug-induced gastropathy: clinical and economic implications of a single-tablet formulation of diclofenac/misoprostol. (5/526)

Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used to manage arthritis. While controlling symptoms and improving quality of life, NSAID use is associated with gastroduodenal injury and a 2%-4% annual risk for symptomatic gastroduodenal ulceration, hemorrhage, and perforation. This requires clinicians to balance the efficacy of NSAIDs against the potential risk of serious gastrointestinal events. Identification and stratification of risk can help guide the optimal approach for arthritis management of individual patients or large populations such as managed care organizations. NSAID-induced gastroenteropathy carries considerable economic consequences; 46% of arthritis costs are related to managing serious adverse events. It is reasonable to assume that these costs may not be incurred if high-risk patients are recognized and optimally managed. Newer therapies with proven safety margins present an attractive option, especially for patients at higher risk. The single-tablet formulations of diclofenac and misoprostol (Arthrotec) offer an alternative in managing NSAID patients because of their inherent safety profile. Studies with diclofenac/misoprostol indicate its effectiveness in treating signs and symptoms of arthritis and in reducing the incidence of NSAID-induced gastroenteropathy. As such, this agent may provide improved medical and economic outcomes. This review discusses the clinical aspects of NSAID-induced gastroenteropathy, including available preventive therapies. Approaches to assessing patients' risk for developing complications, and the relationship of medical risk and economic outcomes, are also examined. Although not all patients require preventive therapy, patients with heightened risk may benefit clinically and economically from gastroprotective NSAIDs. Additional research or modeling may provide further insight into the economic implications of managing and preventing NSAID-induced gastroenteropathy.  (+info)

The cost-effectiveness of treatment with lamivudine and zidovudine compared with zidovudine alone: a comparison of Markov model and trial data estimates. (6/526)

In this paper, we present a Markov model for estimating the cost-effectiveness of combination therapy with lamivudine (LMV) and zidovudine (ZDV) compared with ZDV alone. We also compare the predictions of the Markov model for the impact of combination therapy on trial period costs with the actual impact of combination therapy on selected trial period costs estimated from data collected during the clinical trials. In the Markov model, disease stages were defined by CD4 cell count. Based on clinical trial data for patients with CD4 counts higher than 100 cells/mm3, the model assumed that the CD4 cell count level could be maintained above the level at the initiation of therapy for 6.5 months with monotherapy and for 18 months with combination therapy. After this period, transition rates for natural disease progression were used. Incremental lifetime costs and quality-adjusted life years gained with LMV/ZDV compared with ZDV alone were estimated for cohorts of patients initiating antiretroviral therapy at four different CD4 cell count stages. Cost per life year gained varied from $10,000 to $18,000, and cost per quality-adjusted life year gained varied from $14,000 to $27,000. In both cases, the combination therapy was more cost-effective when started earlier in disease progression. These estimates were not sensitive to changes in key parameter values. In addition, the model was used to estimate the impact of combination therapy on healthcare costs during the trial period; these estimated costs were compared with data on the cost of resource use collected during the clinical trial for hospital stays, unscheduled visits, medications, and outpatient procedures. Both the Markov model estimates and the trial data estimates for the trial period showed cost savings in other medical costs, though these were not large enough to completely offset the increased cost for antiretroviral therapy. The model estimates were more conservative than the estimates based on the trial data.  (+info)

Researching the public/private mix in health care in a Thai urban area: methodological approaches. (7/526)

The private health sector has been growing rapidly in many low and middle income countries, yet not enough is known about its sources of finance or characteristics of its users. Moreover, health care reform measures are leading to alterations in the mix of public and private finance and provision, increasing further the need for information. This paper presents and evaluates some research methods which can be used to collect information relevant to considering policies on the public/private mix. They comprise a household survey, a health diary and interview survey, a bed census, and a health resource survey. Each method is described as it was used in a study in a large urban setting in Thailand, and strengths and weaknesses of the methods are identified. The use of data to estimate the shares of public and private finance and provision, and particularly private sources of finance of public hospitals and public sources of finance for private hospitals, is demonstrated. Policy issues highlighted by the data are identified.  (+info)

The effects of group size and group economic factors on collaboration: a study of the financial performance of rural hospitals in consortia. (8/526)

STUDY QUESTIONS: To determine factors that distinguish effective rural hospital consortia from ineffective ones in terms of their ability to improve members' financial performance. Two questions in particular were addressed: (1) Do large consortia have a greater collective impact on their members? (2) Does a consortium's economic environment determine the degree of collective impact on members? DATA SOURCES AND STUDY SETTING: Based on the hospital survey conducted during February 1992 by the Robert Wood Johnson Hospital-Based Rural Health Care project of rural hospital consortia. The survey data were augmented with data from Medicare Cost Reports (1985-1991), AHA Annual Surveys (1985-1991), and other secondary data. STUDY DESIGN: Dependent variables were total operating profit, cost per adjusted admission, and revenue per adjusted admission. Control variables included degree of group formalization, degree of inequality of resources among members (group asymmetry), affiliation with other consortium group(s), individual economic environment, common hospital characteristics (bed size, ownership type, system affiliation, case mix, etc.), year (1985-1991), and census region dummies. PRINCIPAL FINDINGS: All dependent variables have a curvilinear association with group size. The optimum group size is somewhere in the neighborhood of 45. This reveals the benefits of collective action (i.e., scale economies and/or synergy effects) and the issue of complexity as group size increases. Across analyses, no strong evidence exists of group economic environment impacts, and the environmental influences come mainly from the local economy rather than from the group economy. CONCLUSION: There may be some success stories of collaboration among hospitals in consortia, and consortium effects vary across different collaborations. RELEVANCE/IMPACT: When studying consortia, it makes sense to develop a typology of groups based on some performance indicators. The results of this study imply that government, rural communities, and consortium staff and steering committees should forge the consortium concept by expanding membership in order to gain greater financial benefits for individual hospitals.  (+info)

The paper suggests an econometric methodology for testing the effectiveness of reforms implemented in one major step, i.e., discrete reforms. The methodology is based on the exogeneity properties of variables in an econometric model. The paper specifies the preconditions for setting up an appropriate model; suggests an economic interpretation of the tests for weak, strong, and superexogeneity; and illustrates this methodology by applying it to two cases of instantaneous reforms. The exogeneity properties of variables in a correctly specified econometric model may help uncover information on the preparation, implementation, and the outcome of such reforms, which could be useful for future policy advice.
TY - JOUR. T1 - Estimating the price elasticity of US electricity demand. AU - Smith, V. Kerry. PY - 1980/4. Y1 - 1980/4. N2 - The use of a single electricity price has been seen as a major shortcoming of econometric models of residential electricity demand. It has been suggested that demand estimation should be based on the full rate schedule. This suggestion is evaluated here by examining demand estimates for 27 investor-owned US utilities over the period 1957-1972. The specification errors resulting from using an average revenue price are measured. It is found that statistically valid demand estimated do not necessarily require information on tariff schedules, but that state-wide aggregates of elasticity may often be inapplicable to individual utilities..

It has been suggested that demand estimation should be based on the full rate schedule. This suggestion ...
A dynamic econometric model of the hog-pork industry is developed. Specification of major behavioral relationships is initially based on theoretical considerations of the rational behavior of microeconomic units. But the theoretical relationships does not give useful information about the expected behavior in the system. Moreover, most economic time series data are happenstance, thus, a certain amount of experimental modeling with an econometric model is conducted. The model consists of four equations, they are the slaughter number, retail pork supply, retail demand and marketing margin equations. The retail pork supply equation is an identity equation. All other equations combined the preinformation which is generated by time series analysis with the economic model specified on the basis of economic theory. The retail demand and marketing margin equations are a simultaneous system. Both 2SLS and 3SLS estimation methods are used ...
Downloadable (with restrictions)! This study offers a simultaneous equations model of the birth process with seven endogenous variables: four birth inputs (maternal smoking, maternal drinking, first trimester prenatal care, and maternal weight gain) and three birth outputs (gestational age, birth length, and birth weight). The data are taken from the National Longitudinal Survey of Youth. Our analysis conditions on twenty-nine exogenous variables including four racial dummies to account for the widely cited racial differences in birth outputs. We find that there is sizeable correlation between the disturbances in the four input and three output equations and among output disturbances, and that results from our simultaneous equations model are substantially different from those using the single-equation approach. It appears that the High/Low Risk Birth Weight Puzzle remains unresolved under our modeling framework. Copyright Springer-Verlag 2003
Downloadable! A forecast produced by an econometric model is a weighted aggregate of predetermined variables in the model. In many models the number of predetermined variables used is very large, often exceeding the number of observations. A method is proposed in this paper for testing an econometric model as an aggregator of the information in these predetermined variables relative to a specified subset of them. The test, called the information aggregation (IA) test, tests whether the model makes effective use of the information in the predetermined variables or whether a smaller information set carries as much information. The method can also be used to test one model against another. The method is used to test the Fair model as an information aggregator. The Fair model is also tested against two relatively non theoretical models: a VAR model and an autoregressive components (AC) model. The AC model, which is new in this paper, estimates an autoregressive equation for each component of real GNP,

This course, the first of two, focuses on the development and use of single-equation econometric models that enable analysts to better understand their economic/business landscape and to improve their ability to make sound economic/business forecasts. Through hands-on exercises, participants gain knowledge of the practical elements of applied econometric analysis. The overall aims are to sharpen the quantitative, statistical, and analytical skills of participants in dealing with problems and issues related to business and economics as well as to improve communication skills in reporting findings to decision makers.
An important subset of the literature on agglomeration externalities hypothesizes that intrasectoral and intersectoral relations are endogenously determined in models of local and regional economic growth. Remarkably, structural adjustment models describing the spatio-temporal dynamics of population and employment levels or growth traditionally do not include intersectoral economic dynamics. This paper argues and shows that ... read more allowing for economic linkages across sectors in these models adds considerable value, especially in forecasting. An econometric model of population-employment dynamics, in which sectoral variations in economic development are explicitly taken into account, is applied to a large urban planning policy proposal in the Netherlands. The empirical analyses suggest that population dynamics are largely exogenous, population changes drive employment in particular in the industry and retail sectors, and employment in all sectors depends strongly on intersectoral ...
This master thesis attempts to estimate the short-run and long-run price and income elasticities of crude oil demand in ten IEA member-countries for the time period 1980-2009. Specifically, the price and income elasticities for Sweden, Denmark, Spain, Portugal, Turkey, Finland, Italy, Germany, USA, and Japan are estimated. Crude oil consumption is a function of four explanatory variables: real oil prices, real GDP per capita, oil consumption lagged one year and a time trend representing technological improvements. The econometric model that is used is a multiple regression model derived from an adaption of Nerloves partial adjustment model. Empirical results reveal that elasticities (both price and income) are lower in the short-run and hence more inelastic, indicating that countries need time to respond to changes in price or income. Econometric estimations illustrate that oil consumption is highly price inelastic both in short-run and long-run. Income elasticities are more elastic than price ...
Ecosystem services are benefits people derive from resources in ecosystems. Playa lakes in the Southern High Plains region of North America provide several ecosystem services for humans, including recharge to the Ogallala aquifer. The Ogallala aquifer occupies 450,000 km2, it is part of eight states, and provides irrigation water to over 25% of the irrigated land in the United States. The recharge provided by playas potentially makes them important and valuable in this region. We develop an econometric model (with spatial aspects) to determine how playas affect the water level of irrigation wells and estimate the economic value to farmers of playa ecosystem services in recharging the water in those wells. We find that, in some instances, additional playa surface area may have a small but statistically significant effect on well drawdown (and, we infer, on recharge) on nearby wells, but that the value of the additional water is likely too small to significantly affect private management decisions.

The problems with Chinas regional industrial overcapacity are often influenced by local governments. This study constructs a framework that includes the resource and environmental costs to analyze overcapacity using the non-radial direction distance function and the price method to measure industrial capacity utilization and market segmentation in 29 provinces in China from 2002 to 2014. The empirical analysis of the spatial panel econometric model shows that (1) the industrial capacity utilization in Chinas provinces has a ladder-type distribution with a gradual decrease from east to west and there is a severe overcapacity in the traditional heavy industry areas; (2) local government intervention has serious negative effects on regional industry utilization and factor market segmentation more significantly inhibits the utilization rate of regional industry than commodity market segmentation; (3) economic openness improves the utilization rate of industrial capacity while the internet ...
The sub-discipline of regional economics deals with dissimilar economic performances across space. In trying to understand this, several theoretical perspectives may be drawn upon, and used to justify policies.

Lee A. Lillard, director of the Retirement Research Center at the University of Michigan, senior research scientist at its Institute for Social Research, and professor of economics, developed a unique method for analyzing the rich compendium of data collected by the Panel Study of Income Dynamics (PSID) since its inception in 1968. Lee died in December 2000, and his colleagues at PSID decided to provide the fruits of his work to the research community so others might benefit from an exploration of his techniques and methodologies for analyzing data. Lee created what he called clean processes to investigate a number of dynamic behaviors that are measured longitudinally in PSID, such as employment, marriage-divorce, and fertility. He and his programmers and research assistants put these processes into a consistent framework, and made decisions about how to resolve inconsistencies, missing items, etc. Data from the files can be entered, as appropriate, in dynamic econometric models of related and ...
The explanation of aggregate and sectoral investment behavior has been one of the less successful endeavors in empirical economics. Existing econometric models have had little success in explaining or predicting investment spending. This may be because most such models fail to account for the irreversibility of most investment spending. With irreversibility, changes in the riskiness of future cash flows or interest rates should in theory dramatically affect the decision to invest - more so than, say, a change in the levels of interest rates. Here I survey some of the empirical support for this proposition, and discuss the implications for investment modelling ...
But those figures too are misleading, because they refer to the cumulative GDP gain from TPP by 2030. Its not clear when the World Bank econometric model assumes TPP will come into effect, but by 2030 its clearly been running for at least ten years, and maybe even 12. That means all of the figures above need to be divided by at least a factor of 10 in order to arrive at the annual boost to growth, which provides a better measure of TPPs impact than the overall figure. So according to the World Banks figures, the US will gain an extra 0.04% GDP per year on average, as a result of TPP; Australia an extra 0.07% annually, and Canada a boost of 0.12% per year. In other words, they differ from the USDAs earlier projection of no measurable impacts on real GDP by amounts that are so small they will be swamped by the general imprecision of the model -- trying to predict what will happen to a big chunk of the global economy out in 2030 is hard, and thats putting it mildly. The fact that two ...
Description: This study compiles and updates the findings of 16 comprehensive state climate action plans and extrapolates the results to the nation. The study then takes those results and using a widely accepted econometric model projects the national impact of these policies on employment, incomes, gross domestic product (GDP) and consumer energy prices. Finally, using the bottom-up data developed by the states and aggregated here, the study models the national impact of major features of the Kerry-Lieberman climate bill under consideration in Congress in 2010. These state action plans and supporting assessments were proposed by over 1,500 stakeholders and technical work group experts appointed by 16 governors and state legislatures to address climate, energy and economic needs through comprehensive, fact-based, consensus-driven, climate action planning processes conducted over the past five years with facilitative and technical assistance by the Center for Climate Strategies. Findings show ...
In this paper we estimate the impacts of climate change on the allocation of time using econometric models that exploit plausibly exogenous variation in daily temperature over time within counties. We find large reductions in U.S. labor supply in industries with high exposure to climate and similarly large decreases in time allocated to outdoor leisure. We also find suggestive evidence of short-run adaptation through temporal substitutions and acclimatization. Given the industrial composition of the US, the net impacts on total employment are likely to be small, but significant changes in leisure time as well as large scale redistributions of income may be consequential. In developing countries, where the industrial base is more typically concentrated in climate-exposed industries and baseline temperatures are already warmer, employment impacts may be considerably larger. ...

The present work intends to analyse the relation between the property structure as a corporate government variable and the levels of corruption. Empirical analysis will be held by two econometric models and the database comes from a questionnaire done by the World Bank to 606 enterprises, for the year 2005. Previous empirical evidence is limited and it has been a matter to consider to carry out the research. The results obtained show that a higher number of majority shareholders in the property, leads to higher levels of corruption. There is a significant percentage of the sales contracts for bribery. Also, the frequency in which payments for own benefits are carried out is reduced, revealing an inverse relation between corruption and percentage of majority shareholders. Also, negotiation with state agencies contribute to corruption. Finance and [-] ...
One in three pre-school children in the developing world is undernourished. As a consequence, their human rights are violated. In addition, they are more likely to have impaired immune systems, poorer cognitive development, lower productivity as adults, and greater susceptibility to diet-related chronic diseases such as hypertension and coronary heart disease later in life. Undernourished female preschoolers are likely to grow into undernourished young women who are more likely to give birth to babies who are undernourished even before they are born, thus perpetuating the inter-generational transmission of deprivation. Reducing these unacceptably high numbers remains a tremendous challenge to public policy. As a guide to the direction of future efforts, this research report examines the success of the efforts of the past 25 years to reduce preschooler undernutrition. The report uses an econometric model to identify the factors associated with the reduction in undernutrition. The formulation of ...

This article analyses determinants for 2001 farmland rental prices from 3,819 farms in Germany. Based on specification tests we estimate a general spatial model to account for both spatial relationships among rental prices of neighbouring farmers and spatially autocorrelated error terms. A €1 per hectare higher rental price in a farmers neighbourhood coincides with a €0.72 higher rental price paid by the farmer. The marginal incidence of EU per-hectare payments paid for eligible arable crop land on rental rates amounts to €0.38 for each additional €1 of premium payments. Regional livestock density, which is indirectly influenced by different policies, is also a major determinant of rental prices. Results are confirmed by sensitivity analyses. Consequently, German farmland rental rates are heavily influenced by agricultural policy instruments and therefore, these policies exhibit substantial distributional effects. ...

Another type of cognitive feeling that is relevant to price cognition is the feeling of knowing. The extant literature on the feeling-of-knowing can address a long-standing conundrum in the pricing literature. Evidence from multiple streams of research suggests that price comparisons can be and are often done nonconsciously, without recalling the comparison standard. Price recall surveys have shown that a majority of consumers are unable to correctly articulate the past prices of products, even seconds after selecting them (Dickson and Sawyer 1990; Le Boutillier et al. 1994; Monroe and Lee 1999). For example, Krishna et al. (1991) found that more than 40 % of consumers were unable to provide a response when asked for the regular prices of products they frequently buy, and only 34 % were correct within 20 cents of the actual price. However, econometric analysis of scanner panel data that captured consumer purchase decisions in retail stores painted a different picture. Such econometric studies ...
The analysis follows standardised WHO-CHOICE guidelines on costing analysis, and estimates patient level costs and programme level costs from the societal perspective. Patient level costs are all costs incurred at the level of contact between the provider and the individual patient. The quantities of resources required in terms of diagnostic tests, drug use, and health centre visits for supervision and monitoring and hospitalisation for each of the interventions were based on WHO treatment protocols and expert opinion of actual practice. Drug costs were based on international drug prices21 with a mark up for international and local transportation costs.22 23 Unit costs of health centre visits and hospital inpatient days were based on econometric analysis by Adam et al,24 while those for laboratory tests and x rays were based on the best available international cost information included in WHO-CHOICEs costing database. Unit costs were combined with resource use patterns to estimate the cost per ...

A Non-Random Walk Down Wall Street is a collection of essays offering empirical evidence that valuable information can be extracted from security prices. Lo and MacKinlay used powerful computers and advanced econometric analysis to test the randomness of security prices. Although this book is a heavy read, the findings should be of interest to technical analysts and chartists. In short, this book documents the presence of predictable components in stock prices. Just prior to this book, Andrew Lo wrote a paper for the Journal of Finance in 2000: Foundations of Technical Analysis: Computational Algorithms, Statistical Inference, and Empirical Implementation. Harry Mamaysky and Jiang Wang also contributed. The papers opening remarks say it all: Technical analysis, also known as charting, has been part of financial practice for many decades, but this discipline has not received the same level of academic scrutiny and acceptance as more traditional approaches such as fundamental analysis. One of ...

Using panel data from a period of water rate reform, this paper estimates the price elasticity of irrigation water demand. Price elasticity is decomposed into the direct effect of water management and the indirect effect of water price on choice of output and irrigation technology. The model is estimated using an instrumental variables strategy to account for the endogeneity of technology and output choices in the water demand equation. Estimation results indicate that the price elasticity of ...
In contrast to traditional methods the elasticity is derived from bilateral price elasticities which relate the net share of switchers between two health insurers not only to their premium difference but also to the market share and premium of the higher priced health insurer. Our new method explains the annual variation in the Dutch market share data better than the traditional methods.. We find in the Dutch social health insurance for the period 1996-2005 rather low negative annual price elasticities ranging between 1 and 0. In that period stickiness of insurer choices was high and less than 5% of the population switched annually from health insurer. This result, however, was in sharp contrast with an exceptional high price elasticity of 7 for the year 2006, where after a major health care reform about 18% of the population switched mostly to lower priced health insurers. Besides large media coverage, one important difference with previous years was that many consumers holding an individual ...
The higher the price elasticity of demand, the lower the sensitivity of market price to shifts of the supply curve. Thus, for necessity goods (such as staple foods and, in the case of petroleum-dependent societies, petroleum products), which have a low price elasticity of demand, the market price is much more sensitive to shifts in supply. In particular, a small supply shock can cause a significant increase in price. The main explanation for this massive shift is that, because of the relative inelasticity of demand to price, the price needs to be increased significantly to induce people to cut down on demand in order to compensate for the reduction in supply. In contrast, for non-essential goods, which generally have a high price elasticity of demand, supply shifts do not generally lead to significant price changes, because small (fractional) changes in price are sufficient to induce buyers to cut back on demand. ...
A definition and the formula Again, the key word is responsiveness, but this time we need to find out how responsive supply is to a given price change (rather than demand). Unsurprisingly, the formula used is very similar to the others in structure: /**/ Where: Es = The price elasticity of supply Δ = change in Qs = Quantity supplied P = Price Using the formula I do not want to dwell on this for two reasons. First, there are far fewer questions in examinations focused on the price elasticity of supply. Examiners prefer demand, where one can analyse the affects on the revenues on the firm in question (see the Learn-It on the Price elasticity of demand). Secondly, the way in which one uses this formula is exactly the same as the way in which one uses the formula for the price elasticity of demand. Try the following examples to check that you agree with me. Click on the appropriate button to reveal the answers. /**/The market price for apples rises from 50p per lb to

Elasticity of demand is mainly useful in Pricing Decisions by Business Firms. The business firms take into account the price elasticity of demand when they take decisions regarding pricing of the goods. This is because change in the price of a product will bring about a change in the quantity demanded depending upon the coefficient of price elasticity. This change in quantity demanded as a result of, say a rise in price by a firm, will affect the total consumers expenditure and will therefore, and affect the revenue of the firm. If the demand for a product of the firm happens to be elastic, then any attempt on the part of the firm to raise the price of its product will bring about a fall in its total revenue. Thus, instead of gaining from the increase in price, it will lose if the demand for its product happens to be elastic. On the other hand, if the demand for the product of a firm happens to be inelastic, then the increase in price by it will raise total revenue. Therefore, for fixing a ...
How Do Prices of Manufactured Cigarettes and Roll-Your-Own Tobacco Affect Demand for these Products? (Regional Study 1; 2020). In this research, price elasticities of two tobacco products MC and RYO are analysed by examining cross-country variation in prices and tobacco consumption and controlling for other relevant characteristics. Therefore, estimated elasticities are cross-country and more specifically, across s-regions within the countries studied. These elasticities indicate if differences in smoking prevalence and/or intensity depend on the differences in prices of MC and RYO..

What We Did: We used manufacturing analytics to develop a pricing analysis framework to identify the impact of change in price of a product on its demand to improve promotion effectiveness for a leading food manufacturer.. The Impact We Made: With the pricing analysis framework, the client was able to design multiple trade promotions for retailers, which led to 8% increment in sales volume.. Summary - Price elasticity of demand model. Being a food manufacturer, it is imperative for the client to optimally price their products within or outside promotions to sustain demand. The client used to purchase pricing analysis from a third party vendor. This was proving to be an expensive affair and the client saw a need to have an in-house team to be able to do it accurately and in a scalable fashion. Mu sigma team enabled the client with the price elasticity exercise at brand / consumer segment level to achieve the required outcome.. About The Client - Large CPG company. The client is a leading food ...
Its no secret that there has been a shift in shopping behavior due to growth in millennial spending power, aging of baby boomers and the growth of online shopping.

Working with the Mexican division of a major global consumer package goods company, a study was conducted to better understand the ROI on marketing spending, coupled with a price elasticity study in a product category where the firm had several leading brands. Besides helping shift consumer and trade spending to brands and programs that delivered a significantly better ROI, the price elasticity study was quickly utilized when there was a major increase in commodity costs. Using the data and incorporating it into a proprietary model, the company revised their previously devised pricing plans resulting in a 20 improvement in profitability versus the annual plan.. ...

Carbon emissions from products contribute to anthropogenic climate change. Because of the growing concern over the environmental impact of production and consumption of consumer goods, carbon footprint information started to appear on labels of several products. In this paper we use both parametric and non-parametric econometric models in order to estimate Egyptian consumers willingness to pay (WTP) for carbon-labeled products. Contingent valuation methods based on log-logistic, log-normal and Weibull regression models revealed that consumers in Egypt are willing to pay a price premium of approximately 75 Egyptian pounds (EP) for carbon-labeled products based on the single-bound dichotomous choice (SBDC) model and up to 90 EP based on the double-bound dichotomous choice (DBDC) model. From a socio-economic perspective, results have also revealed that income, age, gender, and educational level have a significant influence on the respondents WTP. Implications of this study highlight the fact that ...
Seminal papers of Solow (1957) and Swan (1956) stimulated debate among economists on the role of technical change in productivity improvements and for that matter economic growth. The consensus is that technological change accounts for a significant proportion of gross national product (GNP) growth in industrialised economies. In the case of Australia, the aggregate productivity performance was poor in the 1970s and 1980s, but picked up very strongly by the 1990s, and was above the OECD average growth level for the first time in its productivity growth history. However, this high productivity growth rate could not be sustained and Australia started to experience a slowdown in productivity growth since 2000. This study empirically measures the performance of productivity in Australias economy for the period 1950-2005, using an econometric approach. Time-series data are used to develop econometric models that capture the dynamic interactions between GDP, fixed capital, labour units, human ...
These essays examine econometric models of health behavior. The first essay evaluates the Kids N Fitness program, an intervention to reduce childhood overweight and obesity. The second essay uses a Childrens Hospital of Los Angeles private dataset to examine determinants of diabetic glycemic control transitions. The third essay analyzes drinking behavior and the response to spousal death among the elderly, utilizing the Health and Retirement Study panel dataset. In each case, I analyze the health behavior choice controlling for available individual characteristics including economic variables. The models apply rigorous econometric techniques and are explicit about the underlying assumptions.; I find that the Kids N Fitness program is effective at helping overweight children reduce their BMI Z Score. In addition, the analysis points towards the conclusion that more highly trained instructors do not yield improved program efficacy. I find that being a teenager negatively impacts the probability ...
Prior to 1985, ten states adopted some kind of indexing provisions for their personal income tax systems. Seven of these states subsequently suspended their indexing laws for one or more years. In this paper we examine the states experience with income tax indexing and see what lessons can be drawn from it. We describe the indexing statutes, and estimate simple econometric models of both the decisions to adopt indexing and to renege on a promise to index. ...

Tax and Transfer Policy Institute (March 2017). This paper uses detailed information about household supermarket purchases from the Australian Nielsen Homescan Survey to estimate price elasticities of demand for a range of food categories. An instrumental variable strategy is employed to address endogeneity issues. The estimates obtained from our analysis are used to study five scenarios in which the rate of the GST on food categories is increased or in which the tax base is broadened to include currently GST-free categories. Our findings reveal that there is considerable scope for raising revenue by increasing the rate and broadening the tax base. Low-income households (the bottom 40% of the income distribution) can be compensated for the loss in consumption induced by a tax increase. We demonstrate that increasing the rate of the GST from 10% to 15% and broadening the tax base would increase tax revenues by up to $8.6 billion, whereas compensating low-income households would require up to $2.2 ...
In addition, there is mounting anecdotal evidence from country studies that access to telecommunications in rural areas enhances development. The economic benefits of rural ICT access are primarily due to access to information, markets, and increased business opportunities.[3]. Africas ICT situation is by and large poor by international standards. Most Africans do not yet have access to the basic ICT services needed to make or receive a simple telephone call, while the rest of the world is dominated by advanced digital telecommunication systems and the Internet.. Although almost all Sub-Saharan countries are poor by international standards, they exhibit great disparities in coverage by cell telephone systems. Statistics on country-level percentages of urban and rural populations within range of cell phone towers in March, 2004 revealed variation in coverage from 0 to 100%. Rural coverage was negligible or nonexistent in 17 countries [4], but above 47% in the top quartile; urban coverage was ...
Background Food taxes and subsidies are one intervention to address poor diets. Price elasticity (PE) matrices are commonly used to model the change in food purchasing. Usually a PE matrix is generated in one setting then applied to another setting with differing starting consumption and prices of foods. This violates econometric assumptions resulting in likely misestimation of total food consumption. We illustrate rescaling all consumption after applying a PE matrix using a total food expenditure elasticity (TFEe, the expenditure elasticity for all food combined given the policy induced change in the total price of food). We use case studies of NZ$2 per 100g saturated fat (SAFA) tax, NZ$0.4 per 100g sugar tax, and a 20% fruit and vegetable (F&V) subsidy. Methods We estimated changes in food purchasing using a NZ PE matrix applied conventionally, then with TFEe adjustment. Impacts were quantified for total food expenditure and health adjusted life years (HALYs) for the total NZ population alive ...
In practice, water pricing is the main economic instrument used to discourage the wasteful use of residential water. Owing to considerations of affordability, residential water is systematically underpriced because water is essential for life. Such a low price results in water being used inefficiently. This paper proposes a system that supplements the existing price system with a cap-and-trade measure to reconcile conflicts among the goals of residential water use. It forces all people (independent of income) to be faced with reasonable price signals and to use water efficiently. The poor could, however, gain from trade and afford water. By taking advantage of the agent-based model, a simulation of this system applied to Taipei, Taiwan shows that those with lower income per capita are better off under this system even though the equilibrium price of residential water is higher. The simulated average price elasticity of market demand is −0.449 ...
One underexplored factor directly affecting firms use of trademarks relates to the fees associated with obtaining a mark. This paper provides econometric estimates of the fee elasticity of demand for trademark applications. Using a panel of monthly international trademark applications, I find that a 10-percent increase in fees leads to a 2.5-4.0-percent decrease in applications. The econometric analysis also highlights that trademark filings react strongly to economic activity. The results bear implications for literature on the value of trademarks and for the use of trademarks as innovation indicator. Specifically, low elasticity estimates suggest that trademarks provide significant economic value to their owners relative to their costs. However, one must exercise caution when comparing trademark numbers across countries to the extent that fees might differ substantially. de Rassenfosse, Gaetan
PriceElasticity and Taxation Essay. Priceelasticity of demand indicates the connection between the cost ofgoods and the amount demanded by consumers. In other words, itmeasures the response after the price of a product change. Aproduct`s consumption is believed to be price elastic when analteration in the cost of a product or service results in a biggerpercentage variation in demand. Also, the demand is described asprice inelastic when a variation in price results to a smallerpercentage alteration in demand. Although the tax burden depends onthe price elasticity of demand and supply rather than on the sourceof revenue, the burden of tax can fall more on producers or consumersdepending on the circumstance. This paper seeks to compare therelatively inelastic demand with the inelastic demand as it describesthe difference between the collected government tax revenues and theeconomic burden of the tax. Thesource of government revenue is taxes. Nonetheless, taxes reduce bothdemand and supply in the ...
In economics, price elasticity of demand refers to the degree to which demand for a particular good or service changes as a result of changes in price. If a product is highly elastic, a large increase in price should result in a large drop in demand as consumers decide not to buy the newly expensive product. If a product is inelastic, however, a change in price will have no effect on demand for the product.. ...
6. Proportion of Expenditure Items that constitute a smaller amount of expenditure in a consumers family budget tend to have a relatively inelastic demand, e.g., a cinegoer who sees a film once a month is not likely to give it up when the ticket rates are raised. But one who sees a film once every week perhaps may cut down the number of films seen per week. Similarly, a family which enjoys eating out twice a week, may reduce their rejoicing if the rates go up. But may not hold true in case of a family which does the same only on somebodys birthday in the house. Cheap or small expenditure items like matches, sugar, kerosene candles, broomstick tend to have more demand in elasticity than expensive or large expenditure items..

This was the topic of a post here in 2014, which got 1 (one) comment.. Price elasticity means how much demand will be reduced if price goes up.. Thats an important point now. Some people think that Bitcoin fees need to be low or zero, or users will switch to something else, and Bitcoin will be doomed.. The question if that is right depends on the question if and how much demand is elastic.. Right now empiric data doesnt point to high elasticity. Fees are way up, but there are still enough users to keep block size fluctuating around 850k.. My best estimate for average transaction size is somewhat more than $1,000. Bitcoin is moving around $300 million a day, with around 260,000 transactions.. For an $1,000 transaction, obviously saving a couple of dimes in fees is not a strong consideration. So it makes sense to expect low elasticity at the present level (average fee of less than $1).. So the answer would be: Yes, some users will be priced out of Bitcoin without larger blocks. But right now, ...

  • This is an important selection criterion when the models are run, because they are designed to use the relationship between the various labour market indicators and their macroeconomic correlates (such as per capita GDP, GDP growth rates, demographic trends and country and time dummy variables) in order to produce estimates of the labour market indicators where no data exist. (ilo.org)
