small and large stakes risk aversion implications of concavity calibration for decision theory abstract a growing literature reports the conclusions that a expected utility theory does not provide a plausible theory of risk aversion for both small stakes and large stakes gambles and b this decision theory should be replaced with an alternative theory characterized by loss aversion this paper explains that the arguments in previous literature fail to support these conclusions either concavity calibration has no general implication for expected utility theory or it has problematic implications for all decision theories that involve concave transformations utility or value functions of positive money payoffs which makes loss aversion irrelevant to the argument

what drives health care expenditure baumol s model of unbalanced growth revisited the share of health care expenditure in gdp rises rapidly in virtually all oecd countries causing increasing concern among politicians and the general public yet economists have to date failed to reach an agreement on what the main determinants of this development are this paper revisits baumol s baumol w j 1967 macroeconomics of unbalanced growth the anatomy of urban crisis american economic review 57 3 415 426 model of unbalanced growth showing that the latter offers a ready explanation for the observed inexorable rise in health care expenditure the main implication of baumol s model in this context is that health care expenditure is driven by wage increases in excess of productivity growth this hypothesis is tested empirically using data from a panel of 19 oecd countries our tests yield robust evidence in favor of baumol s theory

preference heterogeneity in experiments comparing the field and laboratory do laboratory experiments provide a reliable basis for measuring field preferences economists recognize that preferences can differ across individuals but only a few attempts have been made to elicit individual preferences for representative samples of a population in a particular geographical area region or country our primary objective is to directly compare estimates of preferences elicited from a convenience sample and the estimates for the wider population from which that sample is drawn we examine the strengths and weaknesses of laboratory and field experiments to detect differences in preferences over risk and time that are associated with standard observable characteristics of the individual

estimating intertemporal allocation parameters using synthetic residual estimation we present a novel structural estimation procedure for models of intertemporal allocation this is based on modelling expectations errors directly we refer to it as synthetic residual estimation sre the flexibility of sre allows us to account for measurement error in consumption and for heterogeneity in intertemporal allocation parameters an investigation of the small sample properties of the sre estimator indicates that it dominates generalized method of moments gmm estimation of both exact and approximate euler equations in the case when we have short panels and noisy consumption data we apply sre to two panels drawn from the panel study of income dynamics psid and estimate the joint distribution of the discount factor and the elasticity of intertemporal substitution we reject strongly homogeneity of the discount factor and the elasticity of intertemporal substitution we find that on average the more educated are more patient and less willing to substitute intertemporally than the less educated within education strata patience and willingness to substitute are positively correlated 2010 the review of economic studies limited

nontraded goods oil price increases and the current account abstract an intertemporal maximizing model is used to examine the current account response to oil price increases the analysis shows that the introduction of a nontraded goods sector influences the current account response whether the current account worsens or improves depends crucially on relative production technologies in the traded and nontraded goods sectors

pigou meets mirrlees on the irrelevance of tax distortions for the second best pigouvian tax this paper extends the mirrlees 1971 model of optimal income redistribution with optimal corrective taxes to internalize consumption externalities using general utility structures and exploring both linear and non linear taxes it is demonstrated that the optimal second best tax on an externality generating good should not be corrected for the marginal cost of public funds since it equals one in the optimal tax system in the optimum distortions of income taxes are equal to marginal redistributional gains if the government does not have access to a non distortionary marginal source of finance the marginal cost of public funds can be either larger or smaller than one depending on subjective preferences for income redistribution the optimal second best corrective tax is then either higher or lower than the pigouvian level the findings in this paper generalize and amend prior results based on representative agent models shedding new light on the weak double dividend hypothesis and on the welfare gains of recycling revenue from environmental taxes

decisions error and heterogeneity probabilistic choices or choice errors may play an important supporting role in shaping observed risky choices and a variety of restrictions on such choice probabilities play the role of identifying restrictions in empirical decision research we test six restrictions in the context of common ratio effect data for a general class of theories of risky choice two restrictions one for aggregate and one for individual data are supported but none of the heterogeneity restrictions that make the aggregate data model powerful survive scrutiny nor do estimable parametric versions of the individual data model there is room for new stochastic identifying restrictions in empirical decision research

hypothetical intertemporal consumption choices the paper extends and replicates part of the analysis by barsky juster kimball and shapiro 1997 which exploits hypothetical choices among different consumption streams to infer intertemporal substitution elasticities and rates of time preference we use a new and much larger dataset than barsky et al furthermore we estimate structural models of intertemporal choice while parameterizing the parameters of interest as a function of relevant individual characteristics we also consider lobehaviorallc extensions like habit formation models with habit formation appear to be superior to models with intertemporally additive preferences

are women more risk averse we find that single women exhibit relatively more risk aversion in financial decision making than single men using u s sample data we examine household holdings of risky assets to determine whether there are gender differences in financial risk taking as wealth increases the proportion of wealth held as risky assets is estimated to increase by a smaller amount for single women than for single men gender differences in financial risk taking are also influenced by age race and number of children greater financial risk aversion may provide an explanation for women s lower levels of wealth compared with men s jel j16 d81 g11

public goods self selection and optimal income taxation using the self selection approach to tax analysis this paper derives a modified samuelson rule for the provision of public goods when the government deploys an optimal nonlinear income tax this approach gives a straightforward interpretation of the central result in this area generalises it and provides a simple characterisation of optimal policy in a wide range of circumstances the analysis also emphasises and clarifies the significance of the choice of numeraire for the optimality of decentralising public spending decisions it is well known that the famous samuelson rule for the provision of public goods may not be applicable when the tax revenues used to finance the public goods come from distorting taxes the principle was recognized as long ago as pigou 1947 long before the samuelson rule was devised pigou saw that in addition to the resource cost involved in transferring funds from the private to the public sector there was a deadweight loss involved from this insight he suggested that the criterion for providing public goods should be more stringent than the samuelson rule would later suggest in particular one might expect that the inclusion of the deadweight loss of taxes as part of the cost of providing a public good would lead to a reduction in its optimal provision relative to a situation in which lump sum taxes were available the problem was investigated more systematically by atkinson and stern 1974 who considered the case in which a public good is financed by a set of optimal commodity taxes all individuals were assumed to be identical so efficiency alone dictated the objective they found that no prima facie case could be made for the pigou position that the use of distortionary taxes called for a reduction in the supply of the public good their analysis clearly showed that there were two influences at work when the financing of a public good was by distorting taxes on the one hand

on the determinants of local government performance a two stage nonparametric approach abstract this article analyzes the efficiency of local governments in the comunitat valenciana spain and their main explanatory variables the analysis is performed in two stages firstly efficiency is measured via nonparametric activity analysis techniques specifically we consider both data envelopment analysis dea and free disposable hull fdh techniques the second stage identifies some critical determinants of efficiency focusing on both political and fiscal policy variables in contrast to previous two stage research studies our approach performs the latter attempt via nonparametric smoothing techniques rather than econometric methods such as ols or tobit related techniques results show that efficiency scores especially under the nonconvexity assumption fdh are higher for large municipalities thus there is empirical evidence to suggest that resources may be better allocated by large municipalities however the inefficiency found is not entirely attributable to poor management as second stage analysis reveals both fiscal and political variables to be explicably related to municipality performance moreover the explanatory variables impact on efficiency is robust to the chosen technique either convex dea or nonconvex fdh

health care education and the cost disease a looming crisis for public choice an economic specter haunts the democratic governments of the world s most prosperous economies the rising cost of health care and education casts a shadow over virtually every election while increasing costs of other services play a part in the growth of the homeless population and the deteriorating sanitation of city streets it will be shown here that both an explanation and a solution in principle are available however while the solution is in one sense simple and straightforward in another it poses a problem of frightening magnitude for public choice if the citizens of these countries are willing to do what is necessary for the supply of educational health care and other related services to keep up with the expansion in overall economic output made possible by rising productivity then if my analysis is correct a difficult choice will be required either ever more of gross national product will have to be channeled through the public sector with all the problems we know that to entail or alternatively these services will have to be transferred to private enterprise in fields where private business firms can hope to succeed only if granted an improbably immunity from the temptation of unwise governmental interference this is indeed scylla and charybdis in spades

valuation using multiple price list formats we examine the properties of a popular method for elicitation of valuations from experimental subjects the multiple price list format the main advantages of this format are that it is relatively transparent to subjects and provides simple incentives for truthful revelation the main disadvantages are that it only elicits interval responses and could be susceptible to framing effects we consider extensions to address and evaluate these concerns in the context of eliciting willingness to pay for products we find that the multiple price list can elicit relatively precise valuations for products and that those valuations are robust to possible framing effects it therefore offers an attractive procedure for eliciting valuations for goods all data instructions and statistical results are stored in the exlab digital library at http exlab bus ucf edu

heterogeneity in risky choice behaviour in a broad population we analyse risk preferences using an experiment with real incentives in a representative sample of 1 422 dutch respondents our econometric model incorporates four structural parameters that vary with observed and unobserved characteristics utility curvature loss aversion preferences towards the timing of uncertainty resolution and the propensity to choose randomly rather than on the basis of preferences we find that all four parameters contribute to explaining choice behaviour the structural parameters are significantly associated with socio economic variables but it is essential to incorporate unobserved heterogeneity in each of them to match the rich variety of choice patterns in the data

the causes of government expenditure growth a survey of the u s evidence abstract the growth of government budgets can be broken down into a institutional and institutional components the former component the familiar substitution income and population public goods tax sharing effects is estimated to contribute about two fifths of the growth of u s government spending the latter component rent seeking political redistributions bureaucracy and perceptual informational impedimentia is important too but an exact imputation cannot be asserted given the state of the art in empirical public choice theory the cross effects on spending of the growth of regulation and tax preferences or tax expenditures though interesting is not pursued

envy fairness and political influence in local government wage determination evidence from norway the main question in this paper is do wages of low skilled workers in norwegian local governments adjust to clear the labor market for such workers or are the wages affected by trade unions comparing their wages with other wages inside the local governments the main empirical findings are as follows first wages of low skilled local government employees respond not to wages in the external labor market but to wages of higher skilled and higher paid workers inside the local government second wages are positively associated with the share of socialist politicians in the local council these results are interpreted as support for a union model with internal pay comparisons in norwegian local governments copyright 1995 by the london school of economics and political science

the evolution of attitudes to risk lottery tickets and relative wealth abstract individual attitudes to risk are examined in an evolutionary model males obtain more offspring as a consequence of greater wealth both directly and because this attracts more mates the second effect induces gambling driven by relative wealth and can create pareto inefficiency fair bets involving small losses and large gains are taken if any fair bets at all are taken altogether the model accords with observations concerning bets taken and declined by typical individuals despite settings of widely varying per capita wealth journal of economic literature classification numbers c72 d81

evaluating the econometric evaluations of training programs with experimental data this paper takes the results of an employment and training program thatwas run as a field experiment in which the participants were randomlyassigned into a treatment or a control group and compares these results to the estimates that might have been produced by an econometrician who evaluated the program using the same econometric procedures that have been used in the program evaluation literature this comparison shows that many of these econometric procedures fail toreplicate the experimentally determined results and suggests that researchers should be aware of the potential for specification errorsin other nonexperimental evaluations copyright 1986 by american economic association

does the public sector implode from baumol s cost disease i introduction the origin of the baumol cost disease is lower none productivity growth for services than for manufactures the progressive sector see baumol and brown 1966 and baumol 1967 the public sector in most countries is an important provider of tax financed services such as health education and care the baumol cost disease is accordingly often taken to have fatal consequences for the public sector putting it on an unsustainable trajectory baumol 1993 in one version the argument runs as follows the relative costs of providing services increase and hence more and more resources are needed if the supply of services should match the supply of manufactured goods this leads to an ever increasing tax rate compare lindbeck 2006 and van der ploeg 2007 in another version the tax rate is considered given productivity increases enhance income and thus the tax base leaving more tax revenue however under baumol s cost disease this revenue gain is absorbed by increasing costs just to maintain an unchanged supply of public services an increasing gap between public provision of services and private consumption of manufactures thus evolves which in turn will leave the population increasingly dissatisfied with the public sector this reasoning is often encountered in analyses of fiscal sustainability the aim of such analyses is to assess the financial viability of tax financed welfare arrangements these analyses often make trajectories under the baumol assumption showing that it leads to ever increasing financial problems calling for reforms see for example imf 2014 adding increasing demands for services in particular health services when material living standards increase further adds to these problems 1 see for example hall and jones 2007 and oecd 2013 this appears to leave policy makers in a conundrum either the tax burden is ever increasing leading to an eventual collapse of the economy or the supply of public services would have to be restrained leaving an increasing gap between aspired and realized levels of public service provisions this article takes outset in the baumol assumptions concerning productivity differences baumol growth and asks whether the doomsday implications expounded in the literature and in policy debates are justified this article does not challenge the premises of the baumol argument on differences in productivity growth between manufactures and services 2 but the implications when accounting explicitly for service provision from both the private and public sectors a further starting point is the observation that simple predictions based on baumol growth rely on fixed proportions between private consumption and public service provision as well as neglecting labor supply although the baumol problem has a technological origin its implications cannot be seen independently of preferences and thus private responses as well as the optimal provision of public services this article accordingly differs from the standard literature in three aspects first explicit account is taken of service provision from both the private and public sectors 3 not all services are provided via the public sector and many of the examples used to exemplify the baumol problem are services in private production second a very general formulation of preferences is adopted to capture how technological changes map into changes in key variables and affect the scope for tax financed service provision finally public service provisions and thus taxes are endogenous to analyze how policies respond to the changes induced by the baumol process 4 to focus on the basic implications the model is kept as simple as possible and because no essential intertemporal margins are important the model is static see for example buera and kaboski 2012 rogerson 2008 the main finding of the article is that under baumol growth the doomsday implications for the public sector do not hold

expo power utility a flexible form for absolute and relative risk aversion a new utility function which i call expo power is proposed that exhibits decreasing constant or increasing absolute risk aversion and decreasing or increasing relative risk aversion depending on parameter values numerical analysis suggests that the expo power function performs well in incorporating these risk preference structures and that arbitrary risk preference specifications may lead to biased risk response estimates

optimal provision of public goods a synthesis the standard approach to the optimal provision of public goods highlights the importance of distortionary taxation and distributional concerns a new approach neutralizes distributional concerns by adjusting the income tax schedule we demonstrate that both approaches are derived from the same basic formula we also take the new approach further by deriving an intuitive formula for the optimal level of public goods without imposing strong assumptions on preferences this formula shows that distortionary taxation has a role to play as in the standard approach however the main determinants of optimal provision are different and the modified samuelson rule is likely to lead to underprovision

adjustment to expected and unexpected oil price changes for oil importers differences in economic performance after the 1973 74 oil price increase and after the 1979 80 increase can be attributed to a number of factors including the fact that the 1973 74 oil price increase was unexpected whereas the 1979 80 increase was largely expected in this paper we analyze how an economy s adjustment to expected oil price increases might differ from its adjustment to unexpected increases by expected oil price increases we shall mean ones that were anticipated in the past and by unexpected oil price increases we shall mean those that were not anticipated in the past but occur unexpectedly in the present we model this distinction using a three period model where the periods are called the past present and future this abstract was borrowed from another version of this item

discounting behavior a reconsideration we re evaluate the theory experimental design and econometrics behind claims that individuals exhibit non constant discounting behavior theory points to the importance of controlling for the non linearity of the utility function of individuals since the discount rate is defined over time dated utility flows and not flows of money it also points to a menagerie of functional forms to characterize different types of non constant discounting behavior the implied experimental design calls for individuals to undertake several tasks to allow us to identify these models and to several treatments such as multiple horizons and the effect of allowing for a front end delay on earlier payments the implied econometrics calls for structural estimation of the theoretical models allowing for joint estimation of utility functions and discounting functions using data collected from a representative sample of 413 adult danes in 2009 we draw striking conclusions assuming an exponential discounting model we estimate discount rates to be 5 6 on average this is significantly lower than all previous estimates using controlled experiments we also find no evidence to support quasi hyperbolic discounting or fixed cost discounting and only modest evidence to support other specifications of non constant discounting furthermore the evidence for non constant discounting while statistically significant is not economically significant in terms of the size of the estimated discount rates we undertake extensive robustness checks on these findings including a detailed review of the previous comparable literature

discounting cognition and financial awareness new evidence from a change in the military retirement system the choice given military personnel between an immediate cash payment of 30 000 or a more generous retirement pension permits us to estimate individuals personal discount rates pdrs the resulting pdrs about 7 for enlisted personnel and 2 4 3 for officers are precise and are correlated with a variety of other financial behaviors the pdr is negatively related to educational attainment and the armed forces qualification test but cognition seems to operate through channels other than being better informed better informed individuals were not always measured to be more patient jel d91 d14

risk aversion and incentive effects comment charles a holt and susan k laury 2002 develop an experimental design to determine the risk attitude of an individual they use their observations to argue that increased incentives appear to change risk attitudes leading to greater risk aversion popular utility functions that do not allow for such effects are therefore misspecified building on this finding they estimate a flexible utility function that characterizes their aggregate data well but that does not assume constant absolute or relative risk aversion the basic holt and laury 2002 hl design should become an important tool for the interpretation and design of experiments in which risk attitudes could play a role however their most important result showing the effect of scaling up the stakes of the lottery choice task is confounded by a possible order effect an order effect occurs when prior experience with one task affects behavior in a subsequent task the primary methodological contribution of experiments in economics is to enhance control ideally such control makes the explanatory variables of interest in this case scale orthogonal to other explanatory variables such as order allowing clearer inferences about behavior than one could get from field econometric data we argue that not controlling for order effects results in a misspecification of utility functions that is as important as that of scale the subjects in the hl design were given sequences of three or four tasks as shown in table 1 task 1 involved choices over lotteries with a baseline level of prizes which we will refer to as the 1 scale task 2 involved hypothetical choices over prizes with a scaled up level of prizes either 20 50 or 90 task 3 repeated task 2 but with choices that involved real payoffs task 4 was a return to the baseline task with real 1 prizes in some sessions subjects were not given task 2 or task 3 what could one infer from the comparison of measured risk attitudes in the 1 and 20 tasks in hl unfortunately any observed difference could be due either to the scale of the prizes involved or the task order or some combination of both thus the effect of scale is intrinsically confounded with the possible effect of task order this is a logical flaw in their design which

developments in non expected utility theory the hunt for a descriptive theory of choice under risk this article reviews recent developments in the economic theory of individual decision making under risk since the 1950s it has been known that individual choices violate the standard model of expected utility in predictable ways considerable research effort has now been devoted to the project of developing a superior descriptive model following an overview of non expected utility theories which distinguishes between conventional and non conventional approaches the paper seeks to assess these alternative models in terms of empirical success using laboratory and field data and theoretical usefulness the closing sections reflect on some new directions emerging in this literature

on the ir relevance of distribution and labor supply distortion to government policy should the assessment of government policies such as the provision of public goods and the control of externalities deviate from first best principles to account for distributive effects and the distortionary cost of labor income taxation for example is the optimal extent of public goods provision smaller than indicated by the samuelson rule because finance is distortionary or should environmental regulations fail to internalize externalities fully if the incidence of the regulations is regressive it is suggested that these questions are best addressed by considering distribution neutral implementation in which budget balance is achieved by choosing an adjustment to the income tax that offsets the distributive impact of the policy in question in basic cases both distribution and labor supply distortion are moot because the target policy and the tax adjustment produce offsetting effects on each thus traditional first best principles provide good benchmarks for policy analysis after all moreover even when actual implementation will not be distribution neutral in aggregate distribution neutral policy analysis has many conceptual and practical virtues that render it quite useful to investigators

how can scandinavians tax so much american visitors to scandinavian countries are often puzzled by what they observe despite large income redistribution through distortionary taxes and transfers these are very high income countries they rank among the highest in the world in terms of income per capita as well as most other economic and social outcomes the economic and social success of scandinavia poses important questions for economics and for those arguing against large redistribution based on its supposedly detrimental effect on economic growth and welfare to form a basis for the discussion table 1 shows tax revenues and income tax rates in the three scandinavian countries denmark norway and sweden as compared to other european countries and the united states we see that the tax to gdp ratio and the tax rates on income are much higher in scandinavia than elsewhere the top marginal tax rates are about 60 70 percent in the scandinavian countries as opposed to only 43 percent in the united states the contrast is even more striking when considering the so called participation tax rate which is the effective average tax rate on labor force participation when accounting for the distortions due to income taxes payroll taxes consumption taxes and means tested transfers this tax rate is around 80 percent in the scandinavian countries implying that an average worker entering employment will be able to increase consumption by only 20 percent of earned income due to the combined effect of higher taxes and lower transfers by contrast the average worker in the united states gets to keep 63 percent of earnings when accounting for the full effect of the tax and

budgetary constraints and programmatic choices by flemish subsidized theatres we analyse programmatic choices of flemish theatres and examine how they are affected by the theatres budgetary situation following lancaster s characteristics approach we identify several output characteristics of individual flemish theatres during the period 1980 to 2000 a simultaneous equation approach is used to capture the theatre managers subsidizing government s and consumers behaviour we find that changes in the budgetary situation of a theatre are translated into changes of both the amount and the nature of the theatre s output the budgetary impact on artistic choices has intensified since the introduction of a 4 yearly instead of yearly allocation of subsidies the decrease in financial risk for the individual theatres leads to an increase in artistic risk taking

individual discount rates and smoking evidence from a field experiment in denmark we elicit measures of individual discount rates from a representative sample of the danish population and test two substantive hypotheses the first hypothesis is that smokers have higher individual discount rates than non smokers the second hypothesis is that smokers are more likely to have time inconsistent preferences than non smokers where time inconsistency is indicated by a hyperbolic discounting function we control for the concavity of the utility function in our estimates of individual discount rates and find that male smokers have significantly higher discount rates than male non smokers however smoking has no significant association with discount rates among women this result is robust across exponential and hyperbolic discounting functions we consider the sensitivity of our conclusions to a statistical specification that allows each observation to potentially be generated by more than one latent data generating process

institutions efficiency and the strategic behaviour of sponsors and bureaus abstract the over production associated with bureaucratic production is examined in a general equilibrium environment in which the bureau and its sponsor behave strategically seemingly minor modifications in institutional settings give major differences in nash equilibrium outcomes the non equivalence of institutional settings suggests that over production or under production by bureaus can be a result of the institutions governing the decision process as well as the preferences of the bureau for the size of the bureau

public sector efficiency the roles of political and budgetary institutions fiscal capacity and democratic participation the purpose of this paper is to investigate whether efficiency in public service provision is affected by political and budgetary institutions fiscal capacity and democratic participation in order to address this issue we take advantage of a new global efficiency measure for norwegian local governments we find that high fiscal capacity and a high degree of party fragmentation contribute to low efficiency in addition there is some evidence that democratic participation increases efficiency while a centralized top down budgetary procedure is associated with low efficiency

estimating risk preferences from deductible choice we develop a structural econometric model to estimate risk preferences from data on deductible choices in auto insurance contracts we account for adverse selection by modeling unobserved heterogeneity in both risk claim rate and risk aversion we find large and skewed heterogeneity in risk attitudes in addition women are more risk averse than men risk aversion exhibits a u shape with respect to age and proxies for income and wealth are positively associated with absolute risk aversion finally unobserved heterogeneity in risk aversion is greater than that of risk and as we illustrate has important implications for insurance pricing

estimating individual discount rates in denmark a field experiment we estimate individual discount rates with respect to time streams of money using controlled laboratory experiments these discount rates are elicited by means of field experiments involving real monetary rewards the experiments were carried out across denmark using a representative sample of 268 people between 19 and 75 years of age individual discount rates are estimated for various households differentiated by socio demographic characteristics such as income and age our conclusions are that discount rates are constant over the 12 month to 3 year horizons used in these experiments and that discount rates vary substantially with respect to several socio demographic variables hence we conclude that it would be reasonable to assume constant discount rates for specific household types but not the same rates across all households

prospect theory and energy efficiency abstract investments in energy efficiency entail uncertainty and when faced with uncertainty consumers have been shown to behave according to prospect theory preferences are reference dependent and exhibit loss aversion and probabilities are subjectively weighted using data from a choice experiment eliciting prospect theory parameters i provide evidence that loss averse people are less likely to invest in energy efficiency then i consider policy design under prospect theory when there are also externalities from energy use a higher degree of loss aversion implies a higher subsidy to energy efficiency numerical simulations suggest that the impact of prospect theory on policy may be substantial

does the u s health care sector suffer from baumol s cost disease evidence from the 50 states this study examines if health care costs in the united states are affected by baumol s cost disease it relies on an empirical test proposed by hartwig 2008 and extended by colombier 2010 and uses a panel data set of 50 states over the 1980 2009 period the results suggest that health care costs grow more rapidly when economy wide wage increases exceed productivity gains the findings are fairly robust with respect to time and state fixed effects individual state time trends and two stage least square estimation consequently this study suggests that the u s health care sector suffers from baumol s cost disease

explaining differences in productive efficiency an application to belgian municipalities the purpose of this paper is to measure and explain variations in productive efficiency of municipal governments in belgium technical efficiency is evaluated using a non parametric method based on the free disposal hull fdh reference technology we first calculate input output and graph farrell efficiency measures for a cross section of all 589 belgian municipalities in a second stage of the analysis we explain the calculated differences in efficiency in terms of variables related to the structural characteristics of municipalities and to the institutional environment

dynamic hypothetical bias in discrete choice experiments evidence from measuring the impact of corporate social responsibility on consumers demand abstract this paper is aimed at studying the dynamics of consumers preferences for corporate social responsibility the data come from both a discrete choice experiment dce and a field experiment conducted in a real market setting the results show that in a static setting first month predictions of a standard dce study and real market shares are statistically similar for the various profiles of corporate social responsibility however as time evolves real market shares present some dynamic patterns that are not mirrored by the standard dce predictions the overall conclusion is that differences between real market behavior and dce data can be attributed to the lack of learning experience or adaptation in dce surveys rather than to the hypothetical nature of the experiments

cost disease in defense and public administration baumol and politics william baumol s model predicts a steady increase in relative public sector prices or costs because of the combination of slow productivity growth and wage growth similar to sectors wherein productivity is growing more quickly in this paper we extend the baumol model with political variables and analyze price growth in defense and public administration using norwegian data we find strong support for the mechanism of the baumol model since manufacturing productivity is the most important determinant of relative public sector prices greater political fragmentation has also contributed to the price growth but its quantitative effect is smaller than that of manufacturing productivity an analysis of a labor intensive private service restaurants and cafes supports the broader relevance of the baumol mechanism and the validity of the estimated effect of political fragmentation on the two sectors considered herein

local government grants and income tax revenue redistributive politics in norway 1900 1990 an important aspect of the welfare state is public provision of private goods primarily education and health care in norway the provision of these services has been organized through the local public sector the development of the welfare state has to a large extent been the development of welfare communes the important revenue sources of the local and county governments grants and income tax revenue have been controlled nationally and the paper addresses the determinants of these revenues during 1900 1990 the approach combines a demand model of local public services emphasizing price and income elasticities with a political economy model of central government ideology and strength the decision making is understood as bargaining between the government and interest groups and the political structure consequently is of importance for the policy outcome the analysis shows how politics matter and the results indicate that a minority coalition government implies 30 more grant and income tax revenue to local and county governments than one party majority in the long run

baumol s cost disease and the sustainability of the welfare state if productivity increases more slowly for services than for manufactured goods then services suffer from baumol s cost disease and tend to become relatively more costly over time since the welfare state in all countries is an important supplier of tax financed services this translates into a financial pressure that seems to leave policymakers with a trilemma increase tax distortions cut spending or redistribute less under the assumptions underlying baumol s cost disease we show that these dismal implications are not warranted the welfare state is sustainable and there is even scope for pareto improvements under baumol s cost disease
