design and analysis of simulated consumer choice or allocation experiments an approach based on aggregate data the authors integrate concepts in conjoint analysis and discrete choice theory in econometrics to develop a new approach to the design and analysis of controlled consumer choice or resource allocat

arbitrage and the savings behavior of state governments the federal tax code creates strong incentives for tax arbitrage on the part of state governments this arbitrage activity is illegal and previous research has typically assumed that the constraint against arbitrage activity is binding this paper explicitly tests this proposition by considering whether financial asset holdings increase as the yield spread between taxable and tax exempt securities rises using a data set on 40 state governments over a seven year period i find that there is a significant response to changes in the yield spread one implication of these results is that the tax reform act of 1986 which made even greater efforts to curb arbitrage activity is likely to be ineffective copyright 1990 by mit press

common trends the government s budget constraint and revenue smoothing abstract the requirement that the government s budget be balanced in present value terms is shown to be equivalent to the condition that government expenditures inclusive of interest tax receipts and seignorage be cointegrated the condition is in fact stronger requiring that the deficit inclusive of interest be stationary stationarity of the net of interest deficit is neither necessary nor sufficient for intertemporal budget balance however it does have implications for barro s tax smoothing hypothesis data for the period 1890 1986 are consistent with intertemporal budget balance but not with tax smoothing

how much is too much an investigation of the effect of the number of choice sets context dependence and the choice of bid vectors in choice experiments in a split sample design we examine how the number of choice sets design of the first choice set context dependence and the choice of attribute levels in the cost attribute affect the precision in the elicited preferences in otherwise completely identical choice experiment surveys these issues are investigated for swedish households marginal willingness to pay to reduce power outages our results indicate that neither the number of choice sets nor the design of the first choice set has a significant impact on estimated marginal willingness to pay while the effect was significant for the additive scaling of the cost vector at the end of the article we discuss the implications of our results on future developments and applications of choice experiments

the u s evidence on optimal taxation over time abstract this paper considers a tax rule in which a uniform tax rate over time becomes optimal its implications are that 1 changes in the tax rate should arise only when there are changes in permanent government expenditures and 2 no variable other than permanent government expenditures should be of any value in predicting the tax rate these implications are tested using u s data for 1937 82 empirical results of the tests reveal that in addition to responding to permanent government expenditures the tax rate also responds to temporary defense purchases the general price level and a time trend

the medicaid notch labor supply and welfare participation evidence from eligibility expansions i assess the impact of losing public health insurance on labor market decisions of women by examining a series of medicaid eligibility expansions targeted toward young children these targeted expansions severed the historical tie between afdc and medicaid eligibility the reforms allowed a mother s earnings to increase without losing public health insurance for her young children increasing the income limit for medicaid resulted in a decrease in afdc participation and an increase in labor force participation among these women the effects were large for ever married women and negligible for never married women

does public insurance crowd out private insurance the cost of expanding public sector health programs depends critically on the extent to which public eligibility will cover just the uninsured or will crowd out existing private insurance coverage we estimate the extent of crowd out arising from the expansions of medicaid to pregnant women and children over the 1987 1992 period we estimate that approximately 50 percent of the increase in medicaid coverage was associated with a reduction in private insurance coverage this occurred largely because employees took up employer based insurance less frequently there is also some evidence that employers contributed less for insurance and that workers dropped coverage of dependents

federal taxation and the supply of state debt abstract this paper presents a model of debt finance at the sub national level from which municipal bond supply equations are derived federal tax considerations are shown to be important determinants of the price entering the bond supply equation using data on 40 state governments over a seven year period in the 1980s i show that federal tax rates have an important effect on the supply of municipal bonds independent of the demand side effect that is usually considered in the literature this has implications for the measurement of the tax expenditure associated with tax exempt debt

deficits government expenditures and tax smoothing in the united states 1929 1988 abstract barro s tax smoothing hypothesis tsh implies that the government runs a budget deficit whenever it anticipates the growth rate of national income to increase or the growth rate of its expenditure to decline we test this implication of the hypothesis by examining the implied cross equation restrictions on a vector autoregression var model using u s data for the period ranging from 1929 to 1988 our formal tests reject the hypothesis for the full sample period but cannot reject it for the post 1947 period further investigations show that the statistical rejection should be attributed to sharp differences in the statistical properties of the pre 1947 and the post 1947 data rather than the failure of the hypothesis itself

evaluating the relative strength of product specific factors in fuel switching and stove choice decisions in ethiopia a discrete choice model of household preferences for clean cooking alternatives switching from conventional stoves to modern clean safe and efficient stoves will improve health and social welfare for the 2 7 billion people worldwide that lack reliable access to modern energy services in this paper we critically review some key theoretical dimensions of household consumer behaviour in switching from traditional biomass cooking stoves to modern efficient stoves and fuels we then describe the results of empirical research investigating the determinants of stove choice focusing on the relative strength of product specific factors across three wealth groups a stated preference survey and discrete choice model were developed to understand household decision making associated with cooking stove choice in addis ababa ethiopia the study found that with the exception of price and usage cost factors for the high wealth group the product specific factors that were investigated significantly affect stove and fuel choices the relative strength of factors was assessed in terms of marginal willingness to pay and provides some evidence that consumer preference for higher quality fuels and stoves tends to increase with increasing wealth

a test of the theory of optimal taxation for the united states 1869 1989 a popular theory of optimal tax policies suggests that tax rates should follow a random walk this paper extends the existing empirical literature in three ways first the impact on the marginal utility of consumption when the government chooses a tax plan to smooth the distorting impact of taxes is considered second exogenous changes in the real rate of interest are incorporated into the government s optimal tax plan finally the tax elasticity of output is not constant over time allowing for these changes there is evidence that the government discounts the future attempts to smooth the distorting impact of taxes on the marginal utility of consumption and that the tax elasticity of output moves predictably during wars copyright 1993 by mit press

the flypaper effect what happens to a state s spending when it receives an unconditional grant from the federal government the standard theoretical analysis predicts that the increase in spending will be the same as that generated by an equivalent increase in local incomes or roughly 5 10 percent for most states in contrast numerous empirical analyses have found that spending increases by much more with some estimates near 100 percent this result is known as the flypaper effect since the money appears to stick where it hits the authors review this evidence as well as other studies that find similar behavior in firms

prelaunch forecasting of new automobiles this paper develops and applies a prelaunch model and measurement system to the marketing planning of a new automobile the analysis addresses active search by consumers dealer visits word of mouth communication magazine reviews and production constraints issues that are important in understanding consumer response to durable goods we address these issues with a detailed consumer flow model which monitors and projects key consumer transitions in response to marketing actions a test vs control consumer clinic provides data which with judgment and previous experience are used to calibrate the model to fit the sales history of the control car we illustrate how the model evolved to meet management needs and provided suggestions on advertising dealer training and consumer incentives comparison of the model s predictions to actual sales data suggests reasonable accuracy when an implemented strategy matches the planned strategy

tourists preferences for congestion residents welfare and the ecosystems in a national park the management of national parks and natural areas often faces a balance between the residents welfare the tourist activity and the pressure on ecosystems this paper assesses the benefits for a set of policies designed to address tourist congestion the increase in the welfare of the local populations and the improvements in the ecosystem services coral reefs mangroves dry forests and coastal and sandy ecosystems we utilize a discrete choice experiment approach with the consideration of potential heterogeneity results show that there are three segments of visitors with different preferences for the proposed policies those tourists with higher values for the environmental policies and welfare of the local communities also share a preference for a lower level of congestion at the natural areas the results have implications for managing natural areas at tourist destinations

u s deficits since world war i the tax smoothing theory suggests that deficits would respond particularly to recession temporarily high government spending and anticipated inflation my empirical estimates indicate that a relation of this type is reasonably stable in the u s since at least 1916 in particular the statistical evidence does not support the idea that there has been a shift toward a fiscal policy that generates either more real public debt on average or that generates larger deficits in response to recessions further the deficits for 1982 3 and popular projections formed in 1984 for 1984 5 are consistent with the previous structure the high values of these deficits reflect the customary response to substantial recession interacting with big government and to expected inflation

intertemporal tax smoothing and the government budget surplus canada and the united states this paper shows that if the government smooths taxes then the budget surplus should equal the present discounted value of expected changes in government expenditure this implication of the tax smoothing hypothesis imposes more stringent restrictions on the data than the more usual method of testing whether changes in tax rates follow a random walk the tax smoothing model is applied to the federal government budgets of canada and the united states and in each case receives considerable empirical support copyright 1995 by ohio state university press

consumer willingness to pay to reduce the probability of retail foodborne pathogen contamination abstract the us department of agriculture applies a cost of illness approach to value reductions in morbidity which may understate the projected benefits from proposed food safety improvements by ignoring costs such as pain suffering and worry we use a national survey with a hypothetical food choice experiment to estimate a more comprehensive measure of consumer willingness to pay for food safety improvements our approach differs from previous evaluations of food safety improvements because we 1 provide the respondent with information about the promised change in the probability of pathogen contamination in retail food packages rather than changes in the probability of becoming ill 2 elicit changes in respondents subjective probability of becoming ill and 3 elicit predicted changes in the quantity demanded for products that have enhanced food safety properties we estimate the consumer s choice between a safety enhanced and an existing product the change in subjective probability of contracting foodborne illness associated with the enhanced product and the change in demand for the enhanced product in a manner that recognizes the correlation among unobserved elements the aggregated results suggest benefit estimates that are significantly larger than previous estimates for similar improvements

valuing cultural heritage in developing countries comparing and pooling contingent valuation and choice modelling estimates a substantial part of the united nation s world heritage sites whss can be found in developing countries but many of them are in a bad state thus there is a need to document the social benefits of these global goods in order to justify the costs of restoration and preservation programmes rpps this study adds to the scarce literature on economic benefits of whss in developing countries and reduces the need to perform very uncertain benefit transfers from european or us valuation studies we apply contingent valuation cv and choice modelling cm to estimate the social benefits of rpps for the my son world cultural heritage site in vietnam both to foreign visitors and the local residents we then compare the estimates from the cv and cm methods and pool the results from the two methods the results show that both cv and cm are suited to estimating the economic benefits of preserving cultural heritage of my son the two methods produce very similar results which can be interpreted as a test of convergence validity the pooling results give evidence to show that the cv and cm models have the same underlying preference structures thus these valuation models can be successfully used in cost benefit analyses to assess the benefits to cultural heritage of measures to reduce air pollution soil erosion climate change and other causes to deterioration of cultural heritage sites

fiscal news state budget rules and tax exempt bond yields abstract this paper investigates how state fiscal institutions such as balanced budget rules and restrictions on state debt issuance mediate the bond market reaction to state fiscal news we analyze data on the yields of bonds issued by different states as reported in the chubb relative value survey along with data on state budget forecasts for the period 1988 1998 we find that unexpected deficits are correlated with higher state bond yields this effect is smaller for states with tight antideficit rules than for states without these fiscal rules unexpected deficits have a particularly large effect in raising bond yields of states with tax limits these results suggest that bond market participants view fiscal institutions as relevant in assessing the risk characteristics of tax exempt bonds and that the economic significance of these institutions depends on the state s economic and fiscal circumstances

embracing model uncertainty strategies for response pooling and model averaging econometricians modeling stated preference sp data and most other types of data are confronted with the uncomfortable reality that our knowledge of the true model is limited with only certain variables suggested by the application at hand and general classes of functional forms and error structures suggested by the literature accepting our limited knowledge we pursue strategies for analyzing sp data that are more robust to uncertainties in our knowledge of the true model these include non parametric and parametric likelihood based tests of pooling responses from different elicitation formats and a frequentist based model averaging approach for estimating willingness to pay functions we argue that these strategies lead to increased econometric integrity and empower the ultimate users of models such as policy decision makers and even juries to better assess the robustness of the results we apply these approaches to an sp survey of saltwater angling in alaska which utilized split sample rankings and ratings elicitation methods while an important goal of our paper is to develop practicable modeling strategies that will ultimately lead to more robust conclusions and more confidence by the users of sp results an equally important goal is to engender a critical discussion of how we can make the analysis of sp data more robust

budget spillovers and fiscal policy interdependence evidence from the states abstract this paper formalizes and tests the notion that states expenditures depend on the spending of similarly situated states we find that even after allowing for fixed state effects year effects and common random shocks among neighbors a state government s level of per capita expenditure is positively and significantly affected by the expenditure levels of its neighbors ceteris paribus a one dollar increase in a state s neighbors expenditures increases its own expenditure by over 70 cents

are state and provincial governments tax smoothing evidence from panel data the theory of debt examined here is known variously as efficient taxation over time optimal taxation over time the equilibrium approach to fiscal policy or tax smoothing tax smoothing results when an efficient government fixes tax rates today to minimize the costs of taxation over time given the long run constraint of a balanced budget if the marginal costs of taxation are an increasing function of the amount of resources taxed i e the tax rate then minimization of the total costs of taxation implies that the planned tax rate will be constant over time tax rate changes will be unpredictable and the tax rate will behave as a random walk efficient governments will not adjust tax rates to accommodate temporary changes in expenditures and revenues instead governments will minimize tax rate changes by tax smoothing smoothing tax rates implies that temporary changes in government spending and output result in deficits and surpluses therefore tax smoothing provides a theory of government debt the model is primarily due to barro 1 the goal of this paper is to contribute to our understanding of government debt the focus of this paper is on state and provincial debt or what is generally referred to as state and local debt nearly every state government in the united states has a balanced budget rule however balanced budget rules are not sufficient to rule out tax smoothing as state governments could build up budget surpluses in good times to smooth budgets over the business cycle if state governments are smoothing tax rates then their budget surpluses are endogenous contrary to the state governments provincial governments in canada have no balanced budget rules if provincial governments are smoothing tax rates it could explain the behavior of their budget deficits and surpluses as shown by barro tax smoothing implies that the overall tax rate behaves as a random walk and the tax rate would be a nonstationary time series with a unit root this study examines the tax smoothing hypothesis in two ways first the random walk implication is examined directly by testing the null hypothesis that the tax rate time series has a unit root second if the tax rate behaves as a random walk then changes in the tax rate should be unpredictable from past information if past information can predict tax rate changes this would provide evidence in favor of an alternative hypothesis a rejection of tax smoothing suggests that state and provincial tax rates respond to current

model selection for the mixed logit with bayesian estimation in this paper the mixed logit ml using bayesian methods was employed to examine willingness to pay wtp to consume bread produced with reduced levels of pesticides so as to ameliorate environmental quality from data generated by a choice experiment model comparison used the marginal likelihood which is preferable for bayesian model comparison and testing models containing constant and random parameters for a number of distributions were considered along with models in preference space and wtp space as well as those allowing for misreporting we found strong support for the ml estimated in wtp space little support for fixing the price coefficient a common practice advocated and adopted in the environmental economics literature and weak evidence for misreporting

optimal fiscal and monetary policy in an economy without capital abstract this paper is concerned with the structure and time consistency of optimal fiscal and monetary policy in an economy without capital in a dynamic context optimal taxation means distributing tax distortions over time in a welfare maximizing way for a barter economy our main finding is that with debt commitments of sufficiently rich maturity structure an optimal policy if one exists is time consistent in a monetary economy the idea of optimal taxation must be broadened to include an inflation tax and we find that time consistency does not carry over an optimal inflation tax requires commitment by rules in a sense that has no counterpart in the dynamic theory of ordinary excise taxes the reason time consistency fails in a monetary economy is that nominal assets should from a welfare maximizing point of view always be taxed away via an immediate inflation in a kind of capital levy this emerges as a new possibility when money is introduced into an economy without capital

what you don t know might hurt you some unresolved issues in the design and analysis of discrete choice experiments the papers and comments in this issue focus on four broad areas related to understanding and modeling choices 1 the use of laboratory experiments to improve valuation methods 2 the design of stated preference choice set and choice occasions 3 latent class models as means of identifying and accommodating preference heterogeneity and 4 accommodating uncertainty about the true model modeling ranking and rating tasks and pooling data sources in what follows i offer some comments on each area and briefly discuss several unresolved issues associated with each area closing with some comments about future research opportunities

the effect of consumers real world choice sets on inferences from stated preference surveys for stated preference sp studies we develop a model that assesses the influence of choice set misspecification arising from the omission of perceived substitutes among real world alternatives in the same class of goods this problem is most likely to be present when individuals are allowed to select a no purchase option instead of being forced to choose from an explicit set of sp alternatives with hypothetical attribute levels a convenient feature of our model is that researchers do not need to know exactly which omitted real substitute the individual most prefers only the set of real substitutes that exists in our empirical illustration a comparison of rival models suggests researchers who overlook the presence of perceived real alternatives related to an sp experiment can end up with noticeably biased welfare estimates our more general model suggests that it may be prudent for future sp researchers to anticipate then test and possibly correct for distortions in utility parameter estimates that result from this problem

the effects of changing cost vectors on choices and scale heterogeneity choice experiments ce are widely used to estimate the values of changes in non market goods and services a cost attribute is typically included in a ce questionnaire to enable the estimation of monetary values for changes in the non market attributes presented notwithstanding the central importance of the cost attribute relatively little research has been undertaken on the impacts of varying cost attribute levels on value estimates or on individual heterogeneity in this paper i present results from mixed logit and generalised mixed logit models that account for unobserved idiosyncratic preference and scale heterogeneity respondents are found to anchor their choices on the relative cost levels presented in the survey with results suggesting that people are more sensitive to relative rather than absolute cost vectors however the higher cost levels do not lead to significantly higher value estimates partly because of observed preference heterogeneity towards the environmental attributes an important observation is that scale heterogeneity is important accounting for scale as well as preference heterogeneity in the generalised mixed logit model leads to significantly improved model fit the results indicate significant unobserved error variance across respondents unrelated to whether a high or low cost vector is used

elections and aggregation interpreting econometric analyses of local governments this paper analyzes the provision of local government service under the assumption that fiscal policy is set by local officials in order to maximize the expected number of votes in the next election the model includes both the widely used median voter model and the average voter model as special cases further it is a convenient framework for empirical analyses numerical simulations indicate that the vote maximization model is capable of producing levels of government spending either greater or less than those predicted by the median voter model while exhibiting similar responses to changes in incomes grants prices etc thus the model captures the advantages of the median voter model without its objectionable features many avenues for further work remain i will mention briefly only a few of the most obvious the first is to make housing prices endogenously determined within the model in this way one could examine the role of both fiscal incentives capitalization and political incentives votes in the determination of optimal policies a second extension is to introduce explicitly the possibility of a mobile population and examine in the spirit of tiebout 1956 the effects of voting with your feet within the vote maximization framework the possibilities include both setting policies that de facto concede exit of some fraction of the current residents and or setting policies to attract new residents with particular characteristics another extension is to look at decisions over time despite widespread agreement upon the usefulness of the life cycle model of private consumption the median voter is essentially static it seems a minimal extension to include both government and private consumption in an intertemporal framework unfortunately the median voter may change over time making implementation of the median voter model problematic at best in practice intertemporal issues are important emphasizing the absence of an acceptable framework it is often suggested that elected officials will choose inappropriate intertemporal fiscal policies in response to the short run focus of the electoral process for example it appears plausible that officials will borrow in order to finance higher levels of spending and or lower taxes in the present because future residents are not present to vote against these policies the electoral process produces incorrect incentives in the same way this line of reasoning suggests that officials will undertake too little infrastructure investments because the benefits accrue to future residents one countervailing force is the effects of property capitalization to the extent that the local housing market correctly capitalizes future taxes and services into housing values current residents will be affected by inefficient policies and may use the electoral process to provide correct signals to officials there is another possibility as well to the extent that current officials recognize that inefficient current policies reduce the probability of future re election they have an incentive even in the absence of perfect capitalization to adopt intertemporally appropriate tax and spending policies intuitively the official must care about re election what if the particular individual chooses not to run for office again then to the extent that political parties or machines cause the individual to value the election of his successor i e to the extent that political legacies are important the adopted policies may satisfy the conditions for intertemporal efficiency the vote maximization approach provides a framework in which to analyze these issues lastly one could extend the model to situations in which officials care not only about election but also about the policies themselves this provides not only a different tradeoff between the tastes of the public and private sector but also a natural incentive for officials to seek re election

do credit markets discipline sovereign borrowers evidence from u s states the degree to which credit markets discipline sovereign borrowers is investigated by estimating the supply curve for debt faced by u s states the results generally support an optimistic view of the market discipline hypothesis with credit markets providing incentives for sovereign borrowers to restrain borrowing while the risk premium on bond yields is estimated to increase only gradually at low levels of debt this effect appears to become much larger as debt rises there is also some evidence that credit markets may withhold access to credit at very high levels of debt copyright 1995 by ohio state university press

macroeconomic variables and corporate performance increased economic and financial integration and substantial macroeconomic fluctuations require that corporate managers and investment analysts pay more attention than in the past to the link between the noise that these fluctuations represent and the company s performance past and future for many reasons company managers must weed out the effects of the noise to obtain a clear picture of the company s intrinsic competitiveness and long term sustainable profits the question is to what extent can outside shareholders and investment analysts adopt this approach to corporate performance current reporting practice does not provide these outsiders with an adequate idea of the character and magnitude of the impact of macroeconomic variables on the company the recommendations of international accounting standard 1 presentation of financial statements as revised in 1997 however offer an improvement in this important area this article presents four levels of implementation of ias 1 and what these lev

the impact of offering two versus three alternatives in choice modelling experiments researchers designing choice modelling experiments have some latitude over the number of choice alternatives that can be offered in each choice set there is some evidence that design dimensions including the number of alternatives available in each choice set can influence model outcomes a key issue is whether referendum formats with binary options are preferable to choice sets with multiple alternatives a choice modelling experiment was performed where questionnaires delivered to two split samples differed only according to whether two or three alternatives were offered to respondents in each choice set the results indicate that more robust models could be constructed from the three alternative split compared to the two alternative split one reason for the difference is that respondents tended to display serial non participation in the two alternative format choosing an alternative consistently without regard for changes in the attributes for practitioners of the cm technique the results suggest that it may be preferable to offer more than two alternatives in a choice set that includes a status quo option

pushing subjects beyond rationality with more alternatives in experimental auctions the use of experimental economics in valuation of market and nonmarket goods has grown over the past few years the ability of experimental auctions eus to reveal consumer preferences and their malleability has been praised in previous literature because of the high cost of conducting eus researchers usually present multiple products to participants determining how many products to present has no clear guideline the results of this study show that subjects do not value products the same way across different number of options offered to them the main indicator is the increasing variance in responses for a benchmark product when more products are available with an econometric specification allowing for heteroscedasticity as a function of the number of product offerings the results indicate that the number of goods available for bidding is not to be taken as a trivial task in experimental design for value elicitation

foreign currency translation and changing prices in perfect and complete markets our purpose is to explore some properties of the major methods of foreign currency translation under the assumptions of perfect and complete markets in doing so we identify a set of sufficient conditions under which the various methods possess properties claimed by their advocates moreover the role played by the controversial and elusive translation gain or loss becomes clearly defined neither the properties of the various methods nor the role of the translation gain or loss are obvious notwithstanding the considerable debate during the recent attempt to resolve the issue in the policy domain in order to interpret the disclosures under the various methods of translation it is necessary to make an assumption about the economic forces that induce changes in the exchange rates the perspective we adopt is that changes in exchange rates are driven solely by differential rates of inflation among the respective countries given this assumption we analyze the properties of three accounting models translation methods historical cost accounting with foreign denominated subsidiary financial statements translated at historical rates of exchange compre

the self selection of complexity in choice experiments we investigate whether individuals will voluntarily increase the complexity of the tasks they complete within a discrete choice experiment dce we do this via a self selection of complexity design in which respondents choose whether to face choice sets comprising 3 4 or 6 alternatives we link this approach with the emerging excessive choice effect ece literature we find that 30 of the sample opt for the largest sets we test whether this choice of complexity reveals information about respondents capability commitment we find that it does since those with lowest initial error variance levels are most likely to later select the highest level of task complexity we argue that this result offers insights regarding the design of more cognitively efficient dce designs we consider the matching of respondents to the appropriate level of task complexity as analogous to the principal agent problem with asymmetric information rather than trying to understand respondents cognitive capability or commitment ex ante we propose that participants self select designs that achieve the researcher s objective of minimizing error variance copyright 2012 oxford university press

the state of the art of environmental valuation with discrete choice experiments abstract this paper provides with a review of the state of the art of environmental valuation with discrete choice experiments dces the growing body of literature on this field serves to emphasize the increasing role that dces are playing in environmental decision making in the last decade the paper attempts to cover the full process of undertaking a choice experiment including survey and experimental design econometric analysis of choice data and welfare analysis the research on this field is found to be intense although many challenges are put forward e g choice task complexity and cognitive effort experimental design preference and scale heterogeneity endogeneity or model uncertainty reviewing the state of the art of dces serves to draw attention to the main challenges that this methodological approach will need to overcome in the coming years and to identify the frontiers in discrete choice analysis

the influence of task complexity on consumer choice a latent class model of decision strategy switching the literature indicating that person context and task specific factors cause consumers to utilize different decision strategies has generally failed to affect the specification of choice models used by practitioners and academics alike who still tend to assume an utility maximizing omniscient indefatigable consumer this article 1 introduces decision strategy selection within a maintained compensatory framework into aggregate choice models via latent classes which arise because of task complexity 2 it demonstrates that within an experimental choice task the model reflects changing aggregate preferences as choice complexity changes and as the task progresses the import of these findings for current practice model interpretation and future research needs is examined

designing choice sets for stated preference methods the effects of complexity on choice consistency abstract we vary the complexity of choice sets used in stated preference methods to evaluate the impact on choice consistency we define five measures of complexity that capture either the amount of information or the correlational structure of information in a choice set using these measures as randomly assigned treatments in a large experiment we analyze the consistency of respondents choices using a heteroskedastic multinomial logit model we find that i all of our measures of choice set complexity affect choice consistency ii changes in the correlational structure of information have the largest impact on choice consistency and iii choice complexity significantly distorts welfare estimates our results confirm economists initial worry that moving from contingent valuation to conjoint methods will increase complexity induced choice inconsistency however our analysis also shows that these negative impacts may be mitigated if precautions are taken at the design and estimation stages of stated preference methods

does production labeling stigmatize conventional milk production labeling is a common approach for differentiating otherwise similar products in the marketplace while these labels may convey positive messages to consumers about the new product they may simultaneously stigmatize the conventionally produced product by highlighting perceived problems the net economic result for producers can be negative since consumers may decrease their willingness to pay for the conventional product that dominates the market while the new product has a relatively small market share this experimental research identifies this stigma effect in the case of milk where the introduction of rbst free and organic milk reduces consumers willingness to purchase conventional milk copyright 2009 oxford university press

valuation and accounting for inflation and foreign exchange inflation and foreign exchange raise new issues with respect to accounting representations of equity value for example inflation creates an earnings illusion as an artifact of the mismatching of expenses based on allocations of historical costs with current revenues in determining earnings this mismatching distorts mappings of aggregate earnings and book values into equity value such that value relevant information is lost in this article we consider the consequences of inflation and foreign exchange accounting policies including those contained in accounting standards on the value relevance of bottom line accounting numbers policies are identified that achieve efficient accounting in the sense that aggregate comprehensive earnings and book values are sufficient for an accounting representation of equity value the linear relations that emerge provide predictions on capitalization coefficients that help explain results of empirical inquiries as well our analysis provides a theoretical foundation for policies contained in accounting standards that contributes to the resolution of controversies such as that concerning foreign exchange accounting

health insurance eligibility utilization of medical care and child health two economists applied data from the current population survey and the national health interview survey and state level data on child mortality to a simulation model of utilization of medical care that varies only with the states legislative environment to examine the utilization of medical care and health effects of medicaid eligibility on low income children the models took into consideration the recent expansions of medicaid to low income children 38 of those ineligible for medicaid in 1984 who became eligible due to changes during 1984 1992 were uninsured between 1984 and 1992 expansions of the medicaid program increased the proportion of children eligible for medicaid almost two fold 16 1 vs 31 2 yet coverage rates were always lower than eligibility rates 13 2 vs 16 1 in 1984 and 20 3 vs 31 2 in 1992 and the increase in coverage rates was only about 50 of the increase in eligibility rates during 1984 1992 the probability that a child was eligible for medicaid increased the probability of health insurance coverage by 29 77 when the model considered bias in variables e g a recession in a state the take up rate was only 22 73 nevertheless medicaid markedly increased use of medical care for example eligibility for medicaid increased the likelihood of making a visit to a physicians office in the last two weeks by about 50 it also increased the probability of a child visiting the hospital suggesting inefficiency in the way that providers deliver care to medicaid enrollees medicaid eligibility had a significant effect on reducing child mortality the 15 1 percentage point increase in eligibility during 1984 1992 reduced child mortality by 4 5 when the researchers examined parent assessed subjective health measures medicaid eligibility had no effect on child health medicaid eligibility reduced race and education based disparities in the number of visits and racial differences in mortality yet it may actually intensify current disparities in health care delivery site

u s states the medicaid program and tax smoothing this paper tests the tax smoothing theory by focusing on its implication that a change in permanent government spending should result in an equal sized change in the tax rate the effect of medicaid a state administered federal and state funded medical insurance program for the poor on state tax rates is investigated the medicaid program provides a natural experiment for this test as states are required to cover certain groups in order to receive federal matching money additionally during the 1980s a series of federal mandates greatly increased state medicaid expenditures two stage least squares is used on a panel of u s states 1978 1994 to test whether changes in permanent state medicaid expenditures resulted in equal sized tax rate changes tax smoothing as a positive theory of state government behavior is rejected additionally it is found that this rejection cannot be attributed to the stringency of balanced budget rules
