the private wage sector in cote d ivoire homogeneity or heterogeneity one dominant feature of economic development is change in the structure of the economy some sectors expand while others shrink in response to changes in output markets considerable adjustments must take place in factor markets as well development will therefore proceed more speedily when barriers in the factor markets are minimal whether or not barriers in the labor market exist macroeconomic discussions of labor markets usually assume uninhibited flows between sectors 13 similarly a large literature on earnings of wage workers has treated the wage sector as a homogeneous part of the labor market yet if the wage sector is heterogeneous model estimates have no empirical meaning and policy recommendations have no foundation

individual taxpayer response to tax cuts 1982 1984 with implications for the revenue maximizing tax rate abstract this paper measures the response of taxpayers to the u s personal rate reductions from 1982 to 1984 a baseline income distribution is created to describe what level and distribution could be expected in the absence of tax changes comparison of this baseline with actual tax return data shows that at least one sixth and probably one quarter of the revenue ascribable to the rate reductions was recouped by changes in taxpayer behavior the data also show that federal income tax revenue would have been maximized at a tax rate of about 35 percent and total income tax revenue maximized at a total tax rate of about 40 percent

are more exports always better comparing cash and in kind export subsidies cash and in kind export subsidies are compared it is found that the ability to enhance real farm income via export subsidies is sensitive both to the form cash vs in kind and the point of policy intervention in kind subsidies of the type granted under the export enhancement program can in fact reduce real farm income export subsidies are examined under three separate scenarios no target price or nonrecourse loan programs a target price but no nonrecourse loan program and a nonrecourse loan program but no target price program the presence of a nonrecourse loan program dampens the impacts of both cash and in kind export subsidies before the introduction of the export enhancement program eep two types of export subsidies had been used by the united states a direct cash subsidy for wheat exports and an export payment in kind pik for feed grains cotton rice and nonfat dry milk under the original export pik program exporters showing proof of export sales were given certificates redeemable for commodity credit corporation ccc commodities to be exported cochrane and ryan the eep reintroduced in kind export subsidies in 1985 this paper compares the relative effectiveness of cash and pik export subsidies in increasing agricultural exports real prices and real incomes because agricultural policy ultimately must be judged by how it affects agriculture s relative position in the economy the framework is general equilibrium the model considers the interplay between farmers international middlemen nonfarm producers domestic consumers and foreign consumers the analysis shows that the ability to enhance real farm income is sensitive both to the form cash subsidies versus pik subsidies and point of policy intervention at the farm or export level in particular the results demonstrate that pik subsidies of the type granted under the eep can decrease real farm income from production agriculture s perspective an export pik program even though it raises total agricultural exports is not a sure path to improving agriculture s position in the general economy sometimes less exports are better we first introduce the model the second section reexamines solely for comparative purposes the consequences of introducing cash subsidies to commercial exporters the third section examines in kind export subsidies given to farmers and the fourth considers in kind subsidies to commercial traders the fifth section reexamines these results when the real target price of the agricultural good is fixed next tied pik export subsidies are considered finally the effects of contemporaneous existence of pricesupport operations on the results are discussed

the importance of group coverage how tax policy shaped u s health insurance in 1954 the internal revenue service stipulated that employer contributions to the health insurance plans of their employees were to be excluded from employee taxable income today the tax subsidy is major feature of the u s health care market this paper examines the initial effects of the tax subsidy on the demand for health insurance using previously unexamined data from 1953 and 1958 results suggest that the tax subsidy increased the growth of group insurance particularly among union members and employed persons this is a critical effect because group insurance is not only less expensive than individual insurance but it is also easier to obtain and households with access to group health insurance are far more likely to purchase health insurance coverage than those without similar access by increasing access to group insurance the tax subsidy fostered an increase in the purchase of group health insurance by people who may not have purchased individual coverage and generated institutional change as it cemented an employment based system of group health insurance in the united states this abstract was borrowed from another version of this item

sources of intra industry wage dispersion how much do employers matter observed human capital explains less than half of wage variation in bls industry wage surveys establishment based wage differentials controlling for occupation account for 20 70 percent of intra industry wage variation this corresponds to a standard deviation in wages of 14 percent of the mean almost as large as interindustry wage variation investigation suggests that establishment wage differentials are not random variations or returns to usual measures of human capital

agricultural export subsidies and intermediate goods trade in this paper i examine the effects of export subsidies when a bulk commodity is an intermediate good which is either exported or processed into a higher value agricultural good for domestic or export sale the analysis shows that while the industry producing the subsidized good benefits the industry producing the other good may not a bulk commodity export subsidy may lower the price of the higher value agricultural commodity an export subsidy on the higher value agricultural commodity may lower the bulk commodity s price the outcome depends on the relative excess supply and excess demand elasticities and on the market structure

geography industrial organization and agglomeration this paper makes two contributions to the empirical literature on agglomeration economies first the paper uses a unique and rich database in conjunction with mapping software to measure the geographic extent of agglomerative externalities previous papers have been forced to assume that agglomeration economies are club goods that operate at a metropolitan scale second the paper tests for the existence of organizational agglomeration economies of the kind studied qualitatively by saxenian 1994 this is a potentially important source of increasing returns that previous empirical work has not considered results indicate that localization economies attenuate rapidly and that industrial organization affects the benefits of agglomeration

agglomeration economies and productivity a structural estimation approach using commercial rents we gain more insight into the heterogeneity in firms productivity regarding agglomeration economies given a production function that allows for input factor substitution we identify ratios of firm specific production parameters employing a hedonic price approach we use unique microdata of commercial rents and firm characteristics and employ semiparametric estimation techniques the results show that agglomeration economies capitalize in commercial rents nevertheless expenditure on agglomeration is in general limited for example it is on average only 5 3 of expenditure on office floor space it is much higher in some sectors for retail firms it is about 20 of the expenditure on floor space 2013 the london school of economics and political science

the effect of report cards on consumer choice in the health insurance market we test the effect of report cards on consumer choice in the hmo market federal employees were provided with report cards on a limited basis in 1995 and then on a widespread basis in 1996 exploiting this natural experiment we find that subjective measures of quality and coverage influence plan choices after controlling for plan premiums expected out of pocket expenses and service coverages the effect is stronger within a small sample of new hires compared to a larger sample of existing federal employees we also find evidence that report cards increase the price elasticity of demand for health insurance

the role of income and health risk in the choice of health insurance evidence from australia abstract health insurance choice is investigated using individual data from australia where all people faced a common limited set of possible health insurance policies the data cover two separate regimes one in which insurance choice was for a more generous level of coverage and one in which the choice was a more dramatic one between insurance and no insurance coverage in determining health insurance choice the results indicate a major role for income a major role for premium notably in the first regime and a minor role for observed factors related to health risk aside from age and sex

optimal production with learning by doing abstract this paper characterizes optimal production over time when production cost is a decreasing function of past accumulated output when production exhibits learning by doing monopolistic competitive and socially optimal solutions are considered

compensating differentials and self selection an application to lawyers this paper models individual choice between two types of jobs as dependent on the difference in potential earnings and on preferences for nonpecuniary the model leads to simultaneous estimation of earnings and job choice functions in a manner that takes account of self selection of individuals into the sector of highest utility an application to lawyers choosing between private and public interest law casts doubt on the notion that public interest lawyers are accepting substantially lower earnings by virtue of their choice an impression derived from estimation of earnings functions without accounting for self selection the estimation technique also takes proper account of the choice based nature of the sample which appears to be important

employers provision of pensions and sick pay evidence from the 1990 workplace indistrial relations survey this paper examines the determinants of pension and sick pay provision using data on some 1100 private sector establishments with 25 or more employees it also compares the wages of employees eligible for a pension or for sick pay with the wages of those for whom no such provision was made using ordered probit techniques three levels of provision were examined with respect to each type of benefit no provision provision for white collar employees only and provision for all employees benefit provision was found to be associated with work place size and with the extent to which employment was white collar it was negatively associated with the level of part time working new establishments were slightly less likely to offer pensions than older ones but age had no impact on sick pay provision perhaps because it is less complex and costly than pension provision establishments which recognized trade unions were more likely to offer fringe benefits than those which did not however blue collar unions se

does health insurance reduce illness related worker absenteeism the objective of this article is to examine whether having health insurance reduces illness related absenteeism among older workers a nationally representative sample of 1780 workers in the united states aged 52 64 are drawn from the 2004 2006 health and retirement study hrs binary logistic regressions and censored tobit models are estimated for workers likelihood of missing work days due to illness and the number of illness related work days missed respectively while explicitly addressing the possibility of insurance selection effects the findings suggest that over a 12 month period older workers without health insurance are as likely as insured workers to miss work days due to illness and there are no differences in the number of days missed between insured and uninsured workers however there is strong evidence that poor baseline health onset of new diseases and longer hospitalization significantly increase an older worker s absenteeism at work these results suggest that having health ins

price elasticity and adverse selection in the demand for supplementary health insurance probit regression estimates show the effects of the price of insurance anticipated medical expenditures and other factors on reported decisions about purchasing hypothetically offered supplementary insurance policies the demand estimates can characterize how much supplemental insurance would be purchased under different tax policies affecting health insurance purchases although eliminating the current tax subsidy to insurance is shown to decrease demand the results indicate a substantial demand for supplementary insurance even in the absence of present tax incentives however our results on adverse selection raise concerns about the potential stability of supplemental insurance markets

learning curve spillovers and market performance this paper examines the effect of learning curve spillovers on market structure and performance we derive a simple characterization of the true marginal cost for a broad class of learning curves and use calculated examples to show that spillovers substantially undercut the barriers to entry erected by proprietary learning unlike the case of cost reducing research and development spillovers also tend to improve market performance the increased efficiency of the industrywide reduction process typically outweighs the decrease in firms incentives to reduce costs by expanding output

a note on the substitution between wage and non wage benefits in spot labour markets abstract recent empirical work suggests that spot labour market workers have a strong preference towards wages over fringe benefits this paper provides a theoretical framework based on this finding after a discussion of the utility function and equilibrium the paper proceeds to a comparative statics analysis an important result is that workers spend all extra compensation on wages only this is shown to be true in the case that wage benefits are taxed furthermore proportional taxes have no effect for workers choice between wage and non wage benefits

the elusive wage benefit trade off the case of employer provided health insurance this study shows that standard regressions estimated to measure a trade off between wages and health insurance are misspecified by insufficiently accounting for establishment and firm size an interactive size corrected specification is more likely to reveal a trade off furthermore because insurance decisions are typically made by firms and wages set by establishments the insurance constraint on establishments in multi establishment firms weakens the trade off we use model generated data to show that both factors contribute to the failure in previous research to identify a trade off and data from a cross section of northern californian establishments to test for a trade off in multi establishment and single establishment firms

optimal executive perquisites abstract expenditures by executives on personal perquisites can be optimal for the board of directors using a principal agent model we present a numerical example where the principal can reduce the total cost of compensation for the agent by offering a lower expected bonus and a larger budget allocation from which the agent diverts some funds to perquisites this is optimal when the agent has sufficiently large diminishing marginal utility for perquisites

targeted agricultural export subsidies and social welfare global export subsidies are known to be welfare reducing this paper demonstrates that a small targeted subsidy can increase the welfare of the subsidizing country by exploiting differences in excess demand elasticities targeted export subsidies can also increase the subsidizing country s welfare by exploiting transportation cost differences excess supply elasticities of competitors or excess demand elasticities of markets supplied by competitors when markets are shared an empirical model of the world wheat market illustrates the theoretical conclusions an optimal targeted subsidy scheme causes a small increase in u s welfare but with major disruptions in world trade flows

a new test for supplier inducement and application to the canadian market for dental care abstract the hypothesis that dentists do not induce demand for their services is tested using reduced form estimates of the price elasticity of demand if demand is autonomous shifts in supply for whatever reason should generate equivalent estimates provided access costs change proportionately with shifts in supply if demand inducement is present demand can appear to be very elastic or very inelastic depending on what is causing the shift in supply each of three applications of this test conducted in the context of jointly estimated fee and quantity equations using annual canadian data for 1956 1989 rejects the no inducement hypothesis

models of health plan choice this paper considers alternative approaches to accounting for consumer heterogeneity in econometric models of health plan choice in particular we compare and contrast approaches used by health economists and marketing researchers to explicitly allow for consumer heterogeneity in assessment of plan provider quality and characteristics as a result we are able to identify conditions under which approaches utilized by health economists are preferred over those utilized by marketing researchers and vice versa for example we find that in the absence of data on prior year choice which is often the case of models estimated in the health economics literature it would be valuable to estimate random coefficient models which have not been estimated in such works and in the presence of data on prior year choice which is often the case of models estimated in the marketing literature a model wherein consumer characteristics simply interact with plan specific constants and premium and which has not been estimated in that literature offers better fits than random coefficient semi parametric random coefficient and latent class models which have been previously estimated in that literature the model offers important managerial insights useful for targeting benefits of various plans to different customer segments

farming the tax code the impact of high marginal tax rates on agricultural tax shelters surprisingly little scholarly work has examined the practice of farming the tax code in which accounting losses on agricultural investments are used to shelter other income from taxation economic theory suggests that the amount of investment in agricultural tax shelters is positively related to the marginal tax rate this hypothesis is empirically investigated using a sample of federal individual income tax returns filed for 1983 both the probability of reporting a farm tax loss and the amount of farm losses are increased by a rise in the marginal tax rate especially among upper income taxpayers

demand for medigap insurance by the elderly a micro simulation analysis in this paper a micro simulation model is developed to explain and estimate the optimum medigap insurance coverage for elderly with different levels of insurance premium subsidy the medigap risk exposure is estimated from the 1977 national medical care expenditure utilization survey utilizing the gamma distribution the theory of expected utility maximization is assumed and the model for health insurance demand is operationalized for hypothetical parameters for risk aversion the price elasticity of demand the loading fee and the subsidy with the risk aversion parameter at 0 0005 the price elasticity of medical care demand at 0 5 loading costs at 9 without any subsidy the optimal medigap coinsurance rate is 0 78 and with a premium subsidy of 60 the co insurance rate falls to 12 the hypothetical price elasticity of demand for medigap insurance is estimated to be between 0 44 and 1 02 more than half of the increase in medical expenditure resulting from an increase in premium subsidy from

socially optimal and equilibrium distributions of office activity models with exogenous and endogenous contacts abstract two models of the location of office activities within a city are developed in the first model the pattern of interoffice contacts is specified exogenously as has been traditional in the literature in the second model the contact patterns as well as the distribution of firms are endogenous for both models the market equilibrium distribution of office activities is not socially optimal two sources for this market failure are identified in these models 1 agglomeration economies and 2 transactional externalities arising from firm interdependence and mobility

tax policy toward health insurance and the demand for medical services abstract researchers have argued that the tax subsidy to employer provided health insurance has led to overinsurance excess demand for medical care and to rapid expenditure growth in the medical care sector this paper determines the quantitative significance of this linkage using existing estimates of the elasticities of demand for health insurance and medical services in a static microsimulation model we find that incorrect assumptions about the elasticities of demand and pattern of health insurance coverage led earlier researchers to overestimate the likely impact of the elimination of the tax expenditures for health insurance we estimate using mid range assumptions that complete elimination of the favorable tax treatment of employer contributions to health insurance would reduce the demand for employer sponsored health insurance by 16 27 percent and the overall demand for medical services by about 4 6 percent and not more than 10 percent

people i know job search and social networks we assess the strength of information spillovers relating unemployment duration of workers displaced by firm closures to their former colleagues current employment status displaced specific networks are recovered from a 20 year panel of matched employer employee data spillovers are identified by comparing performances of codisplaced workers a one standard deviation increase in the network employment rate reduces unemployment duration by about 8 the effect is magnified if contacts recently searched for a job and if their current employer is spatially and technologically closer to the displaced worker stronger ties and lower competition for information favor reemployment several indirect tests exclude other interaction mechanisms

alternative models of choice under uncertainty and demand for health insurance the authors test a standard expected utility model and alternative models about how people evaluate risky prospects using data about individuals preferences among health insurance plans a model that assumes people evaluate gains and losses relative to a reference rather than final outcomes treat gains and losses asymmetrically and process certain and uncertain outcomes separately provides a better fit than the standard utility model these findings suggest inertia in health insurance plan choice and that individuals are more responsive to decreases than to increases in the price of insurance copyright 1996 by mit press

productivity and city size a critique of the evidence a critique of two leading articles in the productivity and city size literature results in revised estimates of the productivity advantages of large cities in particular extant estimates of the elasticity of productivity with city size are revised downward by over 100 percent for the manufacturing sector and about 25 percent for the entire urban economy after revision productivity advantages of larger cities are found to be much larger for the nonmanufacturing sector than for the manufacturing sector hence revitalization policies for large cities should be focused on nonmanufacturing sectors

the role of pensions in the labor market a survey of the literature because employer sponsored group pension plans entail agreements between workers and their employers explicitly linking future payment and employment they offer an unusual window into long term employment relationships this review of recent research on pensions explores how pensions influence employee compensation retirement turnover and other matters central to the determination of labor s price and quantity over time the authors also outline some unanswered questions and difficult to reconcile findings because the pension promise involves an explicit and relatively well documented set of statements regarding future contingent payment and employment an examination of the design and operation of employersponsored group pension plans can yield important insights into the long term employment relationship specifically pension research illuminates some important labor market questions in two ways it offers insight into an important element of compensation in its own right and it furthers our understanding of labor markets in which long term

overlapping neighborhoods and housing externalities abstract this paper explores the roles of distance and feedback in neighborhood effects conventional models employ positive feedback and feature neighborhoods that stand apart like islands when neighborhoods overlap a change in land use in one location can induce changes in land use across the city furthermore equilibrium land use is unlikely to be symmetric with negative feedback indirect neighborhood effects can lead to comparative static changes in density and price that cycle these cycles can reduce the ability of coarse zoning to achieve an optimum and can make measurement of neighborhood effects a difficult undertaking

labor market effects of employer provided health insurance i introduction increasing health insurance coverage is arguably an important policy goal the congressional budget office 2003 estimates that in 1998 20 30 million americans had no health insurance for the entire year approximately 40 million were uninsured at a specific point in time in the year and nearly 60 million were without coverage some time during the year most individuals who have health insurance in the united states obtain it through their employer in 1999 65 8 of nonelderly americans had employer provided insurance also called group insurance or employer sponsored insurance either through their own employer or through the employer of another household member see gruber 2001 employer provided insurance plans generally have lower premiums and offer more benefits than individual insurance plans health insurance providers can offer cheaper and better plans to company employees for at least two reasons first the average administrative cost of such plans is lower than individual plans second employment based plans are typically subject to less adverse selection than individual plans particularly so for large employers furthermore the tax subsidy afforded employment based health insurance renders the effective consumer price substantially lower than the cost see pauly 1986 and gruber 2001 together these various factors give a strong incentive for employers to offer and employees to accept coverage as part of their employment contract as employer provided insurance is by far the most prevalent form of coverage in the private sector policy makers look for further expansion of this base as a way to insure the uninsured while avoiding direct public financing as a way to increase employer based health insurance coverage some states either have or are considering government mandates that require employers to provide insurance to certain types of workers 1 the state of hawaii requires private sector employers to offer health insurance to all workers who work for more than 20 h a week and requires these workers to have insurance the state of california is currently considering a similar mandate there is a considerable interest from policy makers on the effects of such mandates on labor market outcomes in this study we report on an experiment that was designed to provide some insights about possible effects of alternative health insurance regulations on the competitive labor market with a particular focus on mandates since we only considered a competitive market setting with complete contracts and no wage rigidities our results may not be directly applicable to all labor market situations 2 however the study provides useful insights about the interaction of health insurance benefit provision wages and employment structure for labor markets where the competitive wage setting and the complete contracts assumptions are reasonable with these limitations in mind our results can be also generalized to other types of employer provided fringe benefits such as paid vacations or pension plans as any government intervention health insurance regulation may affect the labor market theory predicts that in perfectly competitive labor markets health insurance creates no distortionary effects on the labor market equilibrium as long as the coverage is not mandated and there are no wage rigidities 3 all workers who value insurance above its cost of provision are offered insurance and accept it the wages are adjusted downward see rosen 1986 and gruber 2000 summers 1989 used a simple supply and demand analysis to show that the effect of increases in premiums on equilibrium labor hours and wage depends both on the elasticity of labor demand and labor supply and on how fully workers value changes in the cost of health insurance if the demand or the supply of labor is completely inelastic or if workers fully value the insurance then an increase in the premium would result in an equal decrease shift in wages

in kind export subsidies for processed and bulk goods this research analyzes the interaction between a bulk commodity and a processed good under in kind export subsidies an in kind export subsidy lowers the export price of the good on which it is paid the other price changes are ambiguous a numerical model for u s wheat and flour illustrates these conditions given the parameters of the model an in kind payment using wheat lowers flour prices and the export price of wheat the u s domestic wheat price rises when flour is used for the payment u s wheat and flour prices rise while the foreign flour price falls

landscape preferences and patterns of residential development abstract i analyze a model of residential location choice where people derive utility from their proximity to open space when people have such landscape preferences then 1 equilibrium residential development is mixed with undeveloped land 2 equilibrium land price gradients depend sensitively on how land markets are organized are not generally monotonic and may or may not reflect the value of open space and 3 dynamic equilibria generally have the property that more remote areas are developed before more central areas finally when compared to optimal development equilibrium development houses too many residents too close together and remote areas are developed too soon these results imply that equilibrium development may not be sprawling enough and that policies to encourage infill development are not welfare improving

the welfare effects of targeted export subsidies a general equilibrium approach a three country model of export subsidies is developed with an exporter an importer and a neutral country which can act on either side of the market when the neutral country is an exporter the country offering a targeted export subsidy always suffers a welfare loss however when the neutral country is an importer the possibility of a paradoxical result that the subsidizing country can gain and the subsidized country can lose is shown to exist and the conditions under which this result occurs are derived the model fails to provide justification on national welfare grounds for widespread use of targeted export subsidies such as the export enhancement program

the effect of unionism on fringe benefits this study analyzes the impact of unionism on fringes paid to production workers using data on individual establishments it compares fringe expenditures in establishments having the same level of compensation per hour and finds that unionism raises the share of compensation allotted to fringes particularly to pensions vacation pay and life accident and health insurance in addition since unionism also raises the straight time wage rate itself a prime determinant of expenditures on fringes unionism has a very sizeable impact on total fringe expenditures as well as on the fringe share of compensation the union fringe effect exceeds in percentage terms the union wage effect and is sufficiently large to suggest that standard union wage studies understate the union effect on total compensation the study also compares the fringe expenditures of production and non production workers within the same establishment controlling for within establishment pay policies the findings suggest that the pres

what are occupational pension plan entitlements worth in britain the acquisition of rights by workers in private pension plans underpins retirement behaviour recruitment policy and wage structure but there is controversy as to how these individual pension rights should be valued the paper combines four data sets to calculate pension entitlements for a sample of 3000 british workers in 1987 expected scheme tenure is a key variable in valuation younger workers and women face greater initial uncertainty as to their pension outcomes which is resolved as job tenure lengthens given the distribution of tenure durations many employees would obtain higher returns in defined contribution schemes than in a typical final salary defined benefit plan

how elastic is the firm s demand for health insurance abstract we investigate the impact of tax subsidies on the firm s decision to offer insurance and on conditional firm spending on insurance we do so using the micro data underlying the employment cost index which has a major advantage for this exercise the matching of very high quality compensation data with information on a sample of workers in the firm we find that overall there is a moderately sized elasticity of insurance offering with respect to after tax prices 0 25 and a larger elasticity of insurance spending 0 7 we also find that the elasticities are driven primarily by small firms for whom the elasticity is larger and we find that there is significant value added to this employer based data replicating methods from standard micro data sources in our data lead to misleading estimates of these key parameters our simulation results suggest that major tax reform could lead to an enormous reduction in employer provided health insurance spending

constrained choice sets in the u k demand for private medical insurance abstract the paper examines the demand for a privately supplied good private medical insurance in a market dominated by a large public supplier it is argued that the high political visibility of the public alternative means that individual demand for private medical insurance is the outcome of two processes the first process is one of choice set generation the second process is that of the choice between the insurance and the no insurance prospects the factors affecting these processes are discussed and an econometric specification suggested the estimation results indicate the importance of political belief in determining choice sets and of income and health in determining choice between the two prospects

union nonunion compensation differentials across plant sizes evidence from cps 1983 previous empirical work on the relationship between plant size and union nonunion differentials has focused either on wages podgursky 1986 or benefits bramley wunnava and robinson 1989 freeman 1981 this note extends this research by simultaneously focusing on both wages and benefits there are several arguments that can be made in explaining union nonunion differentials across plant sizes 1 union threat effects 2 efficiency wage effects and 3 wage dispersion effects our study focuses on measuring the union nonunion differential in total compensation for this end estimates of total compensation are obtained using mellow s suggestion 1982 for combining hourly wage information with qualitative data on pensions and health insurance and ross s imputations 1989 for holidays and vacations benefits our results based on the may 1983 cps supplemented by bls data on pensions health insurance holidays and vacation benefits indicate significant union nonunion total compensation differentials exist only for workers in establishments with less than 500 workers these results are consistent with podgursky s wage differential findings

tax policy and the demand for health insurance estimates of the price and income elasticities of demand for health insurance are derived from econometric estimates of the parameters of a discrete choice model of health insurance demand using data from a survey of plan choices among a sample of federal government employees the estimated income elasticity 0 01 is similar to most previous estimates the estimated price elasticity 0 16 is in absolute value much less than the earlier previous estimates and somewhat less than the more recent previous estimates possible causes of these differences in price elasticity estimates are discussed

paying for health insurance the trade off between competition and adverse selection we use data on health plan choices by employees of harvard university to compare the benefits of insurance competition with the costs of adverse selection moving to a voucher type system induced significant adverse selection with a welfare loss of 2 to 4 percent of baseline spending but increased competition reduced harvard s premiums by 5 to 8 percent the premium reductions came from insurer profits so while harvard was better off the net effect for society was only the adverse selection loss adverse selection can be minimized by adjusting voucher amounts for individual risk we discuss how such a system would work governments are increasingly turning to market forces as a way to limit the cost of social insurance traditionally social insurance programs were operated as nonmarket goods governments mandated participation in a central program collected revenues to finance the program and ran the insurance system there was no role for competition among suppliers in providing the basic benefit as the costs of social insurance have increased however the centralized model of social insurance is coming under increasing strain in the united states for example recent proposals have called for replacing the medicare program with a health care voucher for the elderly aaron and reischauer 1995 cutler 1996 the voucher would guarantee people a basic insurance plan but the plans would be privately run competition among plans would generate plan premiums and enrollments similarly longstanding proposals for social security reform have called for replacing the current system with a system of individual accounts where people would make saving investment and annuitization decisions on their own advisory council on social security 1996 feldstein 1996 the trend is not just domestic in the united kingdom the national health service has moved to encourage more competition in recent years with the establishment of hospital trusts that bid for patients and partially fixed payments to physicians

health insurance the tradeoff between risk pooling and moral hazard choosing optimal health insurance coverage involves a trade off between the gain from risk reduction and the deadweight loss from moral hazard this paper examines this trade off empirically by estimating both the demand for health insurance and the demand for health services it relies on data from a randomized controlled trial of cost sharing s effects on the use of health services and on the health status for a general non elderly population

agglomeration economies in urban manufacturing industries a case of japanese cities abstract the effects of urban agglomeration economies on productivities in two digit manufacturing industries is estimated using the cross section data of japanese cities in 1979 urbanization and localization economies which are major forms of urban agglomeration economies are explicitly separated the estimates of these economies vary considerably among industries light industries receive more productive advantages from urbanization economies than from localization economies but heavy industries experience these economies more from localization economies than from urbanization economies

taxes fringe benefits and faculty the growth of employee benefits in academe has closely paralleled their economy wide growth this study estimates a complete system describing the demand for benefits and wages using panel data on 1477 institutions of higher learning the demand for benefits is very responsive to changes in real income and the tax price of benefits these conclusions are robust with respect to varying definitions of the tax price treating it as endogenous and accounting for unmeasured individual effects on demand simulations suggest that the tax reform act of 1986 sharply reduced the demand for benefits extrapolating the impact to the entire economy the annual flow of compensation shifted away from benefits by at least 15 billion copyright 1992 by mit press

the elasticity of demand for health maintenance organizations this paper analyzes a national sample of firms where employees faced a choice between a health maintenance organization hmo and a conventional insurer such as blue cross a regression analysis is specified as a partial adjustment model and a logit functional form the long run price elasticity of demand for hmos is estimated to be 0 6 to the extent that employers pass on increases in the total premium the price elasticities facing insurers are higher furthermore the demand for hmos is a negative function of the copayment charged by the hmo for an office visit

search for nonwage job characteristics a test of the reservation wage hypothesis previous structural models of job search behavior have been based upon the reservation wage property this article provides estimates of a more general search model that nests models with the reservation wage property the estimates lead to rejection of the reservation wage property the model includes hours of work in the utility function but other nonwage job characteristics can be included as well an experiment based on the estimated parameters indicates that a significant proportion of job offers would be mistakenly predicted to be accepted or rejected under the restrictions implied by the reservation wage property

tax structure and tax compliance a model of individual tax compliance behavior including evasion and avoidance is developed and estimated the model recognizes the importance of marginal income tax rates payroll tax contributions and benefits and the probabil ity of detection and the penalty on unpaid taxes share equations for avoidance evasion and reported income are estimated using individual level data the estimation results indicate that the tax base rises with higher benefits for payroll tax contributions and falls with higher marginal tax rates the base also falls with more severe penalties and more certain detection of evasion as individuals substitute towards avoid ance income t he methods by which individuals reduce their tax liabilities take a variety of legal and illegal forms all of which are influenced at least in part by incentives created by the tax structure these methods can be broadly classified as avoid ance and evasion tax avoidance is any legal activity that lowers taxes such as worker substitu tion between wage and nonwage compensation tax evasion is the reduction in tax liabilities by illegal means such as underreporting income on tax returns despite extensive but separate literatures on avoidance and evasion we know very little about the tax base response to changes in tax structure it is the purpose of this paper to examine the role that the tax structure plays in compliance there are several reasons for the persistence of the compliance puzzle most prominent is the absence of detailed individual data that would allow a full empirical specification of all factors affecting compliance this difficulty is most evi dent when searching for individual data on the evasion compliance decision even when avail able data have never allowed in the same work the construction of both tax and audit variables 1 clearly data availability is even more problem atic when looking at the choice among evasion avoidance and reported income in addition pre vious work has not looked at the avoidance evasion compliance decision as a joint process even though these decisions are made simultane ously 2 further both strands of the literature have ignored another factor that may affect the compliance decision the benefits that accrue from participation in payroll programs if benefits are tied only to taxable income then their presence gives individuals an incentive to pay taxes in short there has been no empirical work that analyzes the effects of tax rates probabilities penalties and payroll benefits on avoidance and evasion choices of individuals in this paper we provide such an analysis we first develop a theory of individual choice among the three types of compensation we then esti mate the resulting share demand equations using a unique data set which has detailed information on the compensation paid to roughly one quarter of the labor force in jamaica in 1983 from these data we are able to derive measures of reported taxable income evasion income and avoidance income for individual workers in the formal sec tor we are also able to construct measures of the marginal income tax rate marginal payroll taxes and benefits the probability of detection and the penalty on evasion for individual workers we are therefore able to estimate for the first time the responses of workers to the full range of tax structure parameters section i presents the theoretical model of worker compensation choice and the empirical specification of the model section ii discusses the jamaican tax system data and variable con struction are discussed in section iii estimation results are presented in section iv the final section summarizes the main results

substitution between wage and nonwage benefits you gotta be kidding ollie you re just robbing yourself schuylkill mutual offers a terrific deal on keogh and we could plug you in in fact we advise plugging you in on the corporate end so not a nickel comes out of your personal pocket it comes out of the corporate pocket and there s that much less for uncle to tax these poor saps carrying their own premiums with no company input are living in the dark ages there s nothing shady about rigging it this way we re just using the laws the government has put there they want people to take advantage it all works to up the gross national product you know what i mean by keogh don t you you re looking kind of blank john updike p 296
