efficiency and equity effects of reforming the british system of direct taxation a utility based simulation methodology the simulation model presented in this paper shows how an estimated utility index defined over net income and leisure can be used to replicate labor supply behavior individual by individual this methodology is used to evaluate the efficiency and equity effects of two specific revenue neutral reforms of the british system of direct taxation the first reform involves abolishing the married m an s tax allowance the second abolishes this allowance only when the wife exhausts her own tax allowance the second reform is the most efficient and it may also be preferable on distributional grounds copyright 1988 by the london school of economics and political science

tax reform evaluation using non parametric methods sweden 1980 1991 abstract this paper evaluates the tax reform carried out in sweden between 1980 and 1991 we use a recently developed non parametric estimation technique to account for the labor supply responses of married prime aged males we decompose the tax reform to study how the separate components influence hours of work tax revenue and income distribution we find that the decrease in marginal tax rates stimulated labor supply but that the other parts of the reform counteracted this effect the net increase in average desired hours of work was approximately 2 we also find that the reform was under financed and that inequality increased the non parametric predictions are compared to the results based on a flexible parametric model the qualitative results are similar but the quantitative results are quite different

modelling the joint determination of household labour supplies and commodity demands in addition to choosing the allocation of total expenditure between commodities households may also be able to make decisions over the allocation of their time between market work and leisure in both theoretical and empirical work it has often been the case that these decisions have been analysed separately in this paper we stress the theoretical attractions of considering the joint determination of the allocation of time between work and leisure and the allocation of total expenditure between commodities in a utility maximising framework using a sample of individual households we attempt to evaluate the empirical importance of the joint determination model over the separate determination of labour supplies and commodity demands our approach follows that of abbott and ashenfelter i976 phlips i978 barnett i979 deaton and muellbauer i980 and atkinson and stern i980 here we pay particular attention to the following four important aspects of household decision making over commodity demand and labour supply the first concerns the commonly assumed restriction on the household s preferences of weak separability between goods and leisure this assumption allows the estimation of commodity demand systems and engel curves that exclude wage rate variables in cross section household budget data with large variation in wage rates across the sample the invalidity of this assumption would involve a serious mis specification any correlation between the excluded wage variable and the included price income and demographic variables would lead to biased parameter estimates and hence biased estimated elasticities similarly this assumption allows the estimation of labour supply curves that exclude relative price variables and its invalidity could produce biased labour supply elasticities a second aspect of household decision making which we wish to highlight arises from the suspicion commonly alluded to in labour economics texts that primary male workers may not be free to choose their hours of work thus we estimate a matched pair of rationed and unrationed systems following the work of neary and roberts i 980 and deaton and muellbauer i 979 the separability restriction is not unrelated to this point since without it we will see that the rationed hours of work enter demand systems in a complex fashion in effect

constrained pareto optimal taxation of labour and capital incomes abstract with the pareto principle as the sole normative criterion necessary conditions for optimal tax rates on labour and capital incomes are established in an overlapping generations model the individuals in the economy have differing earning abilities and their labour supply is endogenous the analysis focuses on intragenerational aspects and is restricted to linear taxation in steady state

the hausman macurdy controversy why do the results differ across studies the two perhaps most influential empirical labor supply studies carried out in the united states in recent years hausman 1981 and macurdy green and paarsch 1990 report sharply contradicting labor supply estimates in this paper we show that the seemingly irreconcilable views on the size of work disincentive effects and welfare losses can be attributed to the use of differing nonlabor income and wage measures in the two studies monte carlo experiments suggest that the wage measure adopted by macurdy green and paarsch 1990 might cause a severely downward biased wage effect such that data falsely refute the basic notion of utility maximization

labour supply estimation and public policy abstract economists devote considerable energies towards refining their econometric techniques to overcome difficulties connected with conducting empirical research despite advances in technique it is not clear whether further refinement in this direction is worthwhile for policy purposes it may be that no further amount of statistical adjustment of inadequate data will increase understanding and that better data is simply necessary to add to our knowledge but rarely is sufficient credit paid to new forms of data in short econometric technique is emphasized to the neglect of data innovation as if new data were merely lying about waiting for an ingenious suggestion for use this paper surveys advances of the last twenty five years in estimating labour supply for policy purposes with a view towards appreciating the relative contribution of both improvements in econometric technique as well as developments of new data after briefly detailing the key parameters which economists have sought to estimate we describe the early first generation research circa 1970 which is plagued by problems of unobservable variables measurement errors truncation and selectivity bias and non linear budget constraints second generation research constitute attempts to resolve one or more of these difficulties and the respective contribution of econometric technique and new data is acknowledged and assessed including the contribution of data generated by large scale social experiments in which participants are randomly assigned to different guaranteed income plans and their labour supply behaviour measured

nonparametric structural estimation of labor supply in the presence of censoring this paper extends the nonparametric structural method to estimate labor supply developed by blomquist and newey 2002 to handle cases in which there are individuals who do not work the method is then applied to married women in sweden from 1973 to 1999 i find an uncompensated wage elasticity of 0 98 and an income elasticity of 0 10 with the participation margin accounting for one third of the wage elasticity and two thirds of the income elasticity the elasticities vary however a lot over time due to differences in tax systems and demographics i also find results consistent with tax rates being around the net government revenue maximizing rates

labour supply specification and the evaluation of tax reforms this paper investigates the practical importance of the functional specification of labour supply equations for the analysis of tax benefit reform we consider two labour supply specifications one derived from stone geary preferences and the other from a generalisation that relaxes some of the more critical restrictions in that model we use these equations to contrast the effects of two reforms to the u k income tax system one involves income effects almost exclusively while the other implies a significant number of large increases in marginal tax rates

labor supply responses and welfare effects of tax reforms during the late 1 980s and early 1 990s taxation of wage income has undergone a change towards a proportional tax regime in many countries our analysis shows that gradual tax reforms in norway may have removed some of the distortions on worker behavior moreover we find that proportional taxes may reduce the inequality in the distribution of disposable household income yet when the distributional consequences are related to changes in individual welfare we find that rich households may benefit far more than households at the other tail of the income distribution because they earn more without any significant increase in effort

understanding the family gap in pay for women with children as the gender gap in pay between women and men has been narrowing the family gap in pay between mothers and nonmothers has been widening one reason may be the institutional structure in the united states which has emphasized equal pay and opportunity policies but not family policies in contrast to other countries that have implemented both the authors now have evidence on the links between one such family policy and women s pay recent research suggests that maternity leave coverage by raising women s retention after childbirth also raises women s levels of work experience job tenure and pay

labor supply deadweight loss and tax reform act of 1986 a nonparametric evaluation using panel data abstract tax reform act of 1986 tra 1986 has provided an invaluable source of variation in tax rates to study the effects of tax reforms on labor supply in the us most existing studies exploiting variation generated by tra 1986 have used cross sectional variation in tax rates or assumed a linear labor supply function or have not couched their analysis in a nonlinear budget set framework this paper uses the drastic variation in the budget set induced by tra 1986 as a source of identification and combines two novel approaches to estimate behavioral effects of tax reforms i first use nonparametric estimation methods with nonlinear budget sets blomquist soren newey w 2002 nonparametric estimation with nonlinear budget sets econometrica 70 6 2455 2480 to estimate a labor supply function using waves of psid just before and after tra 1986 nonparametric method developed in hausman and newey hausman j whitney newey 1995 nonparametric measurement of exact consumer s surplus and deadweight loss econometrica 63 1145 76 is then applied to estimate the deadweight loss from tra 1986 the nonparametric estimate of the compensated wage elasticity is 0 22 i find that tra 1986 had a small but positive effect on labor supply of men of about 2 at the sample mean tra 1986 was associated with robust reduction in deadweight loss from the pre tra 1986 level and this reduction is positively correlated with income and wages

the optimal linear income tax revisited abstract this paper shows that the mirrlees seade conditions of agent monotonicity and noninferiority of leisure imply the positivity of the optimal marginal income tax rate in sheshinski s model of linear income taxation as well as in the general model the optimal marginal tax rate is bounded above by the rawlsian rate which in turn is bounded by the revenue maximizing rate the optimal marginal tax rate may be arbitrarily close to the rawlsian rate however the optimal marginal tax rate is bounded away from the revenue maximizing rate whenever the individual with the lowest ability works

progressive taxation as social insurance and as a median voter outcome an empirical assessment progressive taxation with a balanced government budget functions as social insurance since individuals with low realized incomes receive a net subsidy from the public sector we calculate the level of taxes that optimally trades off benefits due to such insurance with costs arising from distorted labor supply incentives given the best available evidence on parameter values this optimal rate is roughly 15 percentage points less than the aggregate marginal rate on earned income in sweden as of 1979 we also assess the median voter hypothesis by calculating the rate preferred by the median voter this rate turns out to be about 50 percentage points lower than the actual rate progressive taxation which redistributes income that is a negative income tax can function as insurance since individuals who are unlucky and have low realized incomes are compensated via a net redistribution from the public sector given risk aversion this social insurance is valuable at the same time the provision of insurance generates moral hazard in the form of distorted factor supply incentives thus an optimal pattern of taxation should balance the insurance effects and distortions caused by greater tax progressivity this paper is concerned with the magnitudes of tax rates and progressivity implied by this optimal taxation tradeoff the topic is of particular interest in view of the high tax rates in a number of northern european countries one wonders whether these actual rates may be close to or perhaps even beyond the rates that would optimally balance social insur

assessing empirical approaches for analyzing taxes and labor supply recent surveys on the labor supply responses of men document a divergence in the estimates of substitution and income effects obtained using various estimation approaches generally studies accounting for nonlinear tax schedules in a static setting via a piecewise linear approach produce estimates that typically imply higher substitution and lower income responses than are suggested by empirical work applying other approaches this paper demonstrates that maximum likelihood estimation of a consumer choice problem with nonlinear budget sets implicitly relies on the satisfaction of inequality constraints that translate into behaviorally meaningful restrictions these constraints arise not as a consequence of economic theory but instead as a requirement to create a properly defined statistical model in the analysis of piecewise linear budget sets the implicit constraints required by maximum likelihood in estimation amount to imposition of slutsky conditions at all wage income combinations associated with kink points in the analysis of differentiable budget sets the tacit constraints invoked by maximum likelihood also involve inequality restrictions on slutsky terms the empirical work presented in this study supports the contention that these implicit constraints play a major role in explaining the discrepancies in estimates found in the literature on men s labor supply

the distribution of abilities and the progressive income tax abstract this paper develops a model of endogenous labor supply where agents are uncertain about their future wages assuming risk aversion some redistributive taxation is thus warranted it is shown that for a particular parameterization of the tax system an optimally progressive income tax exists comparative ststics analysis demonstrates how this tax system is effected by changes in the wage distribution the paper ends with a discussion of whether an optimally progressive income tax can be politically sustained it is shown that generally this is not the case in a political system with majority voting

an empirical model of labor supply in a life cycle setting this paper formulates and estimates a structural intertemporal model of labor supply using theoretical characterizations derived from an economic model of lifetime behavior a two step empirical analysis yields estimates of intertemporal and uncompensated substitution effects which provide the information needed to predict the response of hours of work to life cycle wage growth and shifts in the lifetime wage path

allocation inflexibilities female labor supply and housing assets accumulation are women working to pay the mortgage this article uses data from the 1986 canadian family expenditures survey to estimate a life cycle consistent model of household labor supply and commodity demand that incorporates a mortgage qualification constraint based on earnings both the parametric and nonparametric implications of the model suggest that the labor supply of a nontrivial percentage of married women is constrained by mortgage commitments the results of generalized selectivity models of female labor force participation and labor supply show that the positive effect of a high debt service ratio exceeds the negative effect of young children

nonparametric estimation of the impact of taxes on female labor supply this paper proposes a simple extension of nonparametric estimation methods for nonlinear budget set models derived in blomquist and newey 2002 to censored dependent variables the nonparametric method is applied to estimate female labor supply elasticities using data on married women from the 1985 and 1989 waves of the panel study of income dynamics exploiting the substantial variation in budget sets caused by the tax reform act of 1986 as a source of identification the estimated wage elasticities from this new method are 0 56 overall and 0 27 on the intensive margin the income elasticity estimates are close to 0 67 overall and 0 13 on the intensive margin compared with the linear labor supply model the estimated elasticities are usually larger for the nonparametric specifications that account for nonlinear budget sets copyright 2010 john wiley sons ltd

bounds on elasticities with optimization frictions a synthesis of micro and macro evidence on labor supply how can price elasticities be identified when agents face optimization frictions such as adjustment costs or inattention i derive bounds on structural price elasticities that are a function of the observed effect of a price change on demand the size of the price change and the degree of frictions the degree of frictions is measured by the utility losses agents tolerate to deviate from the frictionless optimum the bounds imply that frictions affect intensive margin elasticities much more than extensive margin elasticities i apply these bounds to the literature on labor supply the utility costs of ignoring the tax changes used to identify intensive margin labor supply elasticities are typically less than 1 of earnings as a result small frictions can explain the differences between micro and macro elasticities extensive and intensive margin elasticities and other disparate findings pooling estimates from existing studies i estimate a hicksian labor supply elasticity of 0 33 on the intensive margin and 0 25 on the extensive margin after accounting for frictions

labour supply in italy an empirical analysis of joint household decisions with taxes and quantity constraints this study applies an econometric framework which allows for complex non convex budget sets highly non linear labour supply curves and imperfect markets with institutional constraints a married couple s version of the model is estimated on italian microdata the empirical results show that male labour supply is rather inelastic while labour supply among females especially participation is considerably more elastic the elasticities depend strongly on household income the largest elasticities are found for females living in poor households the results of the tax simulations suggest that there are only modest labour supply responses from replacing the 1987 system by proportional taxes copyright 1999 john wiley sons ltd

a decade of tax and benefit reforms in sweden effects on labour supply welfare and inequality sweden has experienced a sequence of tax and benefit reforms during the last decade in this paper we evaluate these reforms from labour supply welfare and inequality points of view we depart from a household labour supply model simulation of the model reveals that tax and benefit reforms have led to a considerable reduction of the excess burden regarding social welfare and inequality we show that the results depend to a large extent on the income inequality measure and the measure of social welfare as well as the income concept household disposable income or money metric utility

an upper bound on optimal income taxes abstract the message of this paper is very simple a certain range of tax rates determined by supply and demand functions only can be disregarded in linear optimal taxation approaches before any interpersonal utility comparisons are made in particular no marginal tax rate above a certain level can be optimal with respect to pareto inclusive social orderings it is shown that is in general not larger than and sometimes strictly less than the minimal tax rate at which tax revenues are maximal conditions under which is the least upper bound are given and a comparison is made with tax rates obtained by the rawlsian maximin principle

the effect of income taxation on the labor supply of married men in sweden abstract this paper presents labor supply functions estimated on a sample of prime age swedish males the model used takes account of the nonlinear character of individuals budget sets caused by the progressive income tax it also allows preferences to vary between individuals calculations with the estimated functions using a partial equilibrium framework indicate a sizeable effect of the income tax on hours of work the average expected deadweight loss of the income tax is found to be approximately 20 percent of tax revenue

nonlinear taxes and labor supply abstract many empirical studies where hours of work for males are regressed on the gross wage rate or a crudely corrected gross wage rate have yielded wage rate coefficients close to zero it is often believed that this implies that taxes do not affect labor supply in the present paper i show that this is a misinterpretation of the empirical results and that estimated wage rate coefficients often are close to zero because taxes affect labor supply i also show how the use of a proportional tax as an approximation of a nonlinear tax schedule can yield incorrect results when an estimated labor supply function is used to calculate the effect of taxes

unionism mio the cyclical behavior of the labor tv rket in u s manufacturing t he traditional view of market dynamics implies that when demand varies intertemporal variation in quantities exchanged increases as prices become less flexible this reasoning leads to the proposition that wage and price rigidities are important contributors to cyclical fluctuations in output fischer 1977a and gray 1978 based formal macro models on this principle although this view is common it has little empirical support the coexistence of union and nonunion establishments engaged in similar activities contains potential for testing its merits economists have long maintained that in the short run union wages are less flexible than nonunion wages dunlop 1950 rees 1951 this difference should produce larger fluctuations in union employment and hours empirical studies have generally supported the union wage rigidity hypothesis lewis 1963 ashenfelter johnson and pencavel 1972 and hendricks 1981 2 but until recently lack of data precluded analysis of hours and employment definitive answers to the important questions concerning unions influence on cyclical behavior require yet unavailable information matching the behavior of firms and characteristics of workers but data from modem surveys have allowed considerable progress nevertheless it remains a challenge to determine how much of differences observed in the stability of labor utilization are attributable to differences in the stability of demand medoff 1979 and raisian 1979 report that cyclical variation of employment and hours is indeed greater for union labor but despite attempts to allay suspicion that their finding arises primarily from concentration of union members in cyclically sensitive industries both studies leave room for doubt raisian estimated functions relating an individual s wage and weeks worked in a year to a proxy for excess demand that year s unemployment rate in the worker s industry the technique is attractive but raisian s data included workers from the entire economy and the industries were broad aggregates thus differences in the union and nonunion groups compositions may play a large role medoff who confined his study to production workers in manufacturing and used data allowing finer partitions investigated the importance of composition more thoroughly but he did not estimate relationships between adjustments in employment or hours and a measure of demand furthermore his focus was principally on the composition of manhours adjustments rather than their size in this paper i combine the strongest features of the medoff and raisian studies in further examination of the influence of unionism on cyclical fluctuations using current population surveys u s department of commerce 1978 from may of 1973 75 my analysis covers production workers in manufacturing during a period of rising inflation and unemployment the heart of the analysis is a measure of residual employment that quantifies by three digit industry and year shortrun excess demand for labor i construct this variable from employment time series and use it to estimate union nonunion differences in the cyclical responses of unemployment hourly wage rates and hours worked the results are consistent with the view that increasing rigidity in wages amplifies cyclical fluctuations in the utilization of labor the wage regressions add further to the literature s already strong support for the union wage rigidity hypothesis the employment status and hours regressions imply that the sensitivities of employment received for publication august 12 1981 revision accepted for publication february 11 1983 federal reserve bank of dallas this paper is based on my ph d dissertation which was completed at ucla with financial assistance from the rand corporation and the department of labor comments by referees and by participants of labor workshops at ucla and the university of chicago as well as the computation assistance of brian mckee are gratefully acknowledged i am responsible for any remaining errors the views expressed should not be attributed to the federal reserve bank of dallas or the federal reserve system one study is gordon 1982 who concludes page 41 that macroeconomic instability in the united states has been aggravated by the unusually sluggish behavior of nominal wages in the postwar era 2see also johnson 1975 parsley 1980 and moore and raisian 1980

the effect of taxes on male and female labor supply in sweden this paper estimates labor supply functions for married men and women in sweden using data from 1980 taking account of the complete form of individuals budget constraints both linear and quadratic supply functions are estimated with and without random preferences a novel feature is that for women the wage rate and labor supply functions are estimated simultaneously using a full information maximum likelihood method this method yields substantially larger wage and income elasticities than does the previously used two step methods another result is that the quadratic supply function wage elasticities for men and women are virtually the same if the elasticities are evaluated at the same net wage rate and hours of work for men and women the estimated functions are used to calculate the effect of tax reforms

work costs and nonconvex preferences in the estimation of labor supply models abstract works costs have not been adequately handled in labor supply estimation likely due to their complexity we show that if work costs are not accounted for in the budget and time constraints in a structural labor supply model they will be subsumed into the data generating preferences even if underlying preferences over consumption and leisure are convex the presence of unobservable work costs can make these preferences appear nonconvex however we show that under plausible conditions policy relevant calculations such as estimates of the effect of tax changes on labor supply and deadweight loss measures are not affected by the fact that estimated preferences incorporate work costs

optimal linear income taxation with general equilibrium effects on wages abstract the paper argues that the endogeneity of wages may make a considerable difference to optimal linear tax rates in this case there is not only the usual direct redistribution via the fiscal system but also the general equilibrium redistribution due to the change in wages depending on the elasticity of substitution of the production function and the labour supply elasticities these may be reinforcing or opposing it is shown that the general equilibrium effect may plausibly outweigh the direct effect so that net redistribution to the lower paid involves a wage subsidy financed by a lump sum tax

labour supply tax evasion and the marginal cost of public funds an empirical investigation abstract in this paper we extend the concept of marginal cost of public funds itmcf to incorporate tax evasion in the labour market mcf values are also computed from various tax reforms applied to the province of quebec canada 1985 for this purpose a utility based labour supply model that allows for both regular and irregular work activities is used at the benchmark situation the mcf associated with an increase in marginal income tax rates ranges between 1 39 and 1 53 depending upon whether we consider rationing or not moreover the presence of the irregular sector accounts for between 0 02 and 0 05 of this mcf although small in magnitude the impact of the irregular sector increases rapidly with the level of marginal tax rates

a panel study of labour supply and taxes in denmark the labour supply of danish married couples is estimated on a longitudinal sample of about 3000 danish couples observed over the period 1980 86 the influence of the progressive tax system and the effect of the unemployment insurance system are evaluated the definition of unemployment in labour supply functions is discussed and two separate models are estimated where unemployment is considered either completely voluntary or completely involuntary the wage elasticity and the supply effects of tax reduction are estimated to be positive but numerically small for both men and women

progressive income taxes test of efficiency upper bounds on efficient tax rates in a progressive labor income tax schedule are derived within the standard framework of optimal taxation a tax rate is efficient if it is not pareto dominated by any other tax rate the formulas derived are applied to the swedish 1982 tax schedule inefficiency is revealed for the middle income groups copyright 1990 by the editors of the scandinavian journal of economics

overtime pay overtime hours and labor unions this article analyzes the effect of labor unions on overtime compensation and overtime hours estimates from may 1985 current population survey data indicate that unionization increases the prevalence of premium pay for overtime and reduces the incidence and extent of overtime hours along with the finding of previous research that unionized workers are more susceptible to temporary layoffs these results are consistent with a model in which unions use overtime pay to stabilize working hours and expand membership

labor supply and taxes a survey i survey the male and female labor supply literatures focusing on implications for effects of wages and taxes for males i describe and contrast results from three basic types of model static models especially those that account for nonlinear taxes life cycle models with savings and life cycle models with both savings and human capital for women more important distinctions are whether models include fixed costs of work and whether they treat demographics like fertility and marriage and human capital as exogenous or endogenous the literature is characterized by considerable controversy over the responsiveness of labor supply to changes in wages and taxes at least for males it is fair to say that most economists believe labor supply elasticities are small but a sizeable minority of studies that i examine obtain large values hence there is no clear consensus on this point in fact a simple average of hicks elasticities across all the studies i examine is 0 30 several simulation studies have shown that such a value is large enough to generate large welfare costs of income taxation for males i conclude that two factors drive many of the differences in results across studies one factor is use of direct vs ratio wage measures with studies that use the former tending to find larger elasticties another factor is the failure of most studies to account for human capital returns to work experience i argue that this may lead to downward bias in elasticity estimates in a model that includes human capital i show how even modest elasticities as conventionally measured can be consistent with large welfare costs of taxation

pollution related variable input output model the tulsa smsa as a case study abstract regional planners face conflicting goals of promoting regional growth and maintaining a cleaner environment since such growth usually causes polluted air to help understand this complex relationship pollution related variable input output model is developed an interesting feature of this model is its ability to respond to both income and substitution effects the pollution may be created not only by an increase in final demand income effect but also by a change in input cost substitution effect the conventional pollution related input output model w leontief and d ford in input output techniques a brody and a p carter eds north holland amsterdam 1972 fails to capture the pollution effect associated with the substitution effect using the tulsa smsa as a case study the operational impact of entry of a bicycle industry in the area to observe the development potential of other industries and resulting impact on air quality is simulated industrial impact was measured in terms of industrial output personal income employment and regional import and export the pollution impact was measured in terms of particulates sulfur oxides hydrocarbon carbon monoxide and nitrogen oxides the simulation analysis of antipollution control measures emphasized the substitution effect of the pollution related variable input output model as input cost is increased due to antipollution control measures equilibrium prices are increased and technical coefficients are changed as a result of substituting behavior of firms a change in technical coefficients affects both the output and the pollutants

short run politicians and long run tax revenue an empirical assessment a life cycle growth model fit to the u s economy is used to calculate the tax rate that would maximize steady state tax revenue the rate that would be set by a short run politician interested in maximizing current period receipts is also calculated in the current period the capital stock is fixed but labor is a variable factor following the intuition of buchanan and lee 1982 it might be suspected that this fixity of capital would lead the short run politician to set taxes above the steady state revenue maximizing level however such a conclusion does not hold for the cases considered in this study

impact analysis of a water quality enhancing policy a simple input output approach it is generally believed that there exists a trade off between economic activity and environmental quality since pollutants are generated in the process of production and consumption of commodities the literature shows however that there have been relatively few empirical attempts to analyse this trade off relationship this tendency may stem from the fact that there is insufficient data to represent the environmental sector this paper has constructed the environmental sector endogenized multi region input output esemrio model in order to measure the impacts of water quality enhancing policy on the korean economy of two regions recognizing the environmental sector as a resourceusing sector the esemrio model specifically estimates the impacts of the policy on the economy in terms of the policy costs industrial output and employment en regle generale l idee recue c est qu il existe un compromis entre l activite economique et la qualite de l environnement dans la mesure o ugrave la production et

interdependent behavior and the effect of taxes abstract the paper studies the effect of taxes on labor supply in a model with interdependent behavior i e individuals preferences depend on other people s behavior it is found that not taking the interdependency into account can lead to a serious bias in the predicted effects of a tax change it is also shown that interdependent behavior can give rise to spikes in the hours distribution such spikes often have been attributed to quantity constraints

the econometrics of piecewise linear budget constraints a survey and exposition of the maximum likelihood method in this article maximum likelihood techniques for estimating consumer demand functions when budget constraints are piecewise linear are exposited and surveyed consumer demand functions are formally derived under such constraints and it is shown that the functions are themselves nonlinear as a result the econometric problems in estimating such functions are exposited and the importance of the stochastic specification is stressed in particular the specification of both unobserved heterogeneity of preferences and measurement error econometric issues in estimation and testing are discussed and the results of the studies that have been conducted to date are surveyed

reconsidering the economics of demand analysis with kinked budget constraints this paper has two objectives first we identify a problem with the ability of the discrete continuous choice framework and conditional demand functions to fully describe consumer preferences in the presence of kinked budget constraints second we propose and illustrate an alternative preference based method for estimating consumer responses to price changes under these conditions this framework recognizes that commitments to commodities such as pools or outdoor landscaping influence how water consumption responds to price changes as part of the long run consumption adjustments with microdata on household choices this approach could be used to design increasing block rate structures that recognize the differences in water consumption responses with these commitments

taxation and the earnings of husbands and wives evidence from sweden i examine the response of husbands and wives earnings to a tax reform in which husbands and wives tax rates changed independently allowing me to examine the effect of both spouses incentives on each spouse s behavior i analyze the large swedish tax reform of 1990 1991 and find that in response to a compensated fall in one spouse s tax rate each spouse s earnings rise i compare these results to those of simplified econometric models used in the typical setting in which independent variation in each spouse s tax rate is unavailable i find that standard econometric specifications may produce substantially biased estimates

trade unions and optimal labour contracts the recently revived literature on wage and employment determination under trade unionism has in our opinion contributed important insights into the functioning of especially european labour markets it suffers however from a potentially serious deficiency with a few exceptions it neglects completely the issue of risk shifting between workers and employers 3 in particular it disregards entirely the possibility of such risk shifting in economies characterized by more or less encompassing trade unions and centralized wage setting as e g the scandinavian countries the netherlands and austria a typical feature of trade unions in these countries is that they are not only concerned with wage setting but strive in various ways to increase their member s welfare at the expense of the employers by reducing their members exposure to risk for instance unions demand limits to the employers right to require overtime or co lay off workers or they demand occupational safety rules work injury insurance health insurance etc an actual employment contract hence not only entitles the worker to a certain wage and the employer to a certain number of working ho urs in return but is really a package of rights and responsibilities for both parties increases in the amount of insurance such a package provides are sometimes explicitly declared to be obtained through foregone wage increases while risk shifting hence is of prime importance to real world unions the formal trade union literature is almost entirely concerned with wage and employment setting under certainty

tax arbitrage and labor supply we examine how tax avoidance in the form of trade in well functioning asset markets affects the basic labor supply model we show that tax arbitrage has dramatic implications for positive normative and econometric analysis of how taxes affect work incentives

annual inequality and lifetime inequality an estimator of inequality in lifetime incomes is derived it can be computed for a population from the distribution of incomes in one year as a result the estimates are as easily calculated as measurements of annual inequality but can be used as measurements of lifetime inequality estimates from this measure and two others have been computed for selected years since 1947 the results are compared by their implications for the level and trend of inequality in the united states

labour market experience in female wage equations does the experience measure matter many studies have found estimated female wage and labour supply equations to be sensitive in some way to labour market experience although different studies yield different results and it seems there is still more to know about this key human capital variable this is especially so when separate information on individual womes s labour market experience is not available making it necessary to construct some measure of experience from other information this paper takes four such measures of labour market experience and investigates the effects of these upon the coefficients from an estimated wage equation as heckman s 1976 1979 two stage probit selection model is still widely used to test and correct for censoring bias the effect of different measures of experience upon the results from this procedure is also investigated

identifying interdependent behaviour in an empirical model of labour supply in this paper we test a particular form of interdependent behavior namely the hypothesis that individuals choices of hours of work are influenced by the average hours of work in a social reference group there are problems to empirically disentangle the effects of interdependent behavior and preference variation across groups we show that panel data or data from several points in time are needed in the empirical analysis we combine cross section data from 1973 1980 and 1990 our results support the hypothesis of interdependent behavior the implication is that conventional tax policy predictions in which preference interdependencies are neglected will tend to underestimate the effect of a tax reform on hours of work our point estimates suggest that conventional calculations would capture only about a third of the actual change in hours of work

hourly wage rate and taxable labor income responsiveness to changes in marginal tax rates recently a voluminous literature estimating the taxable income elasticity has emerged as an important field in empirical public economics however to a large extent it is still unknown how the hourly wage rate an important component of taxable income reacts to changes in marginal tax rates in this study we use a rich panel data set and a sequence of tax reforms that took place in sweden during the 1980 s to estimate the elasticity of the hourly wage rate with respect to the net of tax rate while carefully accounting for the endogeneity of marginal tax rates as well as other factors that determine wage rates we do find a statistically significant response both among married men and married women the hourly wage rate elasticity with respect to the net of tax rate is estimated to 0 14 0 16 for males and 0 41 0 57 for females in addition we obtain uncompensated taxable labor income elasticities of around 0 21 for men and 0 96 1 44 for women in contrast to earlier studies we also find significant income effects for males accordingly for males the compensated taxable labor income elasticity is about 4 percentage points higher than the uncompensated one

the importance of locational choice in an empirical labour supply model an estimation of labour supply is modelled using the theory of urban household behaviour the major purpose is to test the implicit assumption in previous labour supply studies that work travel and housing consumption are weakly separable from the hours of work the results which are obtained using swedish data imply that the hypothesis of weak separability is clearly rejected we also find that the choice of location affects policy relevant conclusions about the labour supply behaviour

steady state solutions of optimal tax mixes in an overlapping generations model abstract this paper analyzes steady state solutions of optimal tax mixes in an overlapping generations model of heterogeneous individuals with a utilitarian social welfare function a test with cobb douglas utility functions shows that an uneven distribution of the innate abilities leads to high rates of consumption and wage income taxes and a high level of a lump sum transfer the more the labor force works the higher the optimal tax on wage income significant differences in individual preferences lead to low rates of consumption and wage income taxes and to a high rate of interest income tax with identical preferences the rate of interest income tax is zero

national income and marginal taxes a simple model of linear taxation is used to single out different types of tax equilibria sufficient conditions for national income to be a decreasing function of the marginal tax rate are given for each case equilibria are classified according to whether i aggregate labor supply is forward bending ii aggregate labor supply is backward bending iii the equilibrium is a welfare maximum and iv the equilibrium is a political equilibrium

inequality aversion and marginal taxes the concept of a lower bound on optimal linear taxes is analyzed a marginal tax rate is defined to be optimal if the corresponding state of the economy is a welfare maximum for some social welfare function reflecting at least a minimal aversion to inequality the lower bound on optimal tax rates is proved to be strictly positive this tax rate is also calculated in a numerical example based on swedish data the value obtained is 29 per cent

residential demand for electricity under inverted block rates evidence from a controlled experiment block rate structures are used extensively in public utility pricing including residential electricity estimating price elasticities in this context is complicated by the resulting nonlinearity of the consumer s budget constraint this article estimates the demand for electricity under inverted block rates using data from a residential rate experiment the study provides an opportunity to obtain short run price elasticities in an experimental setting and to compare alternative estimators developed for nonlinear budget constraints elasticities of demand with respect to individual components of the block rate are developed using a modification of the structural maximum likelihood estimator

the estimation of british local government expenditure decisions under a piecewise linear budget constraint in the light of the reforms that have affected local government finance in britain the empirical analysis of local government responses to the changes in the grant system has become a topical subject because of its policy implications barnett et al proposed different models to predict the likely impact of the reforms on local government expenditure but never tested ofr the validity of the functional form used in their model the main reason for this omission is related to the piecewise nature of the budget constraint faced by local authorities which complicated the estimation techniques and restricted the choice of the functional forms that could be used the presented here tests for the validity of the functional form using data for the three fiscal years that preceded the poll tax reform namely 1986 87 to 1988 89 and suggests specific tests to compare the parameters obtained using different models the main conclusion of the analysis is that only the behaviour of metropolitan districts is consistent

tax revenue and the marginal cost of public funds in sweden abstract we assess the welfare cost of raising a marginal unit of tax revenue in a balanced budget general equilibrium framework the calculated social cost of an increment of public funds is sensitive to both the specific type of tax increase and the type of public spending used on the margin best guess assumptions on labor supply elasticities yield marginal costs of public funds for different fiscal mixes of between 0 67 and 4 51 at prevailing tax rates in sweden alternative labor supply assumptions well within the range of current estimates substantially affect the results and can imply infinite marginal welfare costs marginal welfare costs are also sensitive to assumptions about both the income and substitution effects of labor supply

the employment of married women in the united kingdom 1970 83 the proportion of married women in employment in the united kingdom grew rapidly during the 1970s rising from around 50 to 60 per cent the paper investigates this change using a time series of cross sections from the family expenditure survey an attempt is made to assess how much of the change was due to trends in the observable characteristics of the population and what part was played by changes in behavioural and other factors reflected in the coefficients of the model a technique of growth accounting is proposed and used to this purpose excerpt

inventories layoffs and the short run demand for labor this paper presents a theoretical and empirical analysis of the short run employment layoff and inventory strategies of firms on average more than two thirds of all layoffs in american manufacturing end in a rehire by the employer of origin martin feldstein 1975 david lilien 1980 these temporary layoffs have recently accounted for about half of all ongoing employer initiated spells of unemployment in that sector see table 1 and have led to a revised interpretation both of the involuntary nature of these separations costas azariadis 1975 feldstein 1976 martin baily 1977 and of the durability of employment relationships evidently a significant proportion of unemployed workers know that the conditions that generated their separations are temporary and so they expect to be recalled within some reasonable time the point of departure for this paper is in interpreting these findings as evidence of a privately and socially efficient stock of excess capacity held against contingent future demands that is as an inventory of a productive input this view leads to empirically refutable hypotheses regarding both the role of temporary layoffs and the circumstances under which they will be important in particular both excess capacity idle resources and inventories are devices by which firms may economize on the costs of rapid adjustments when faced with unstable market conditions george stigler 1939 in such an environment the demands for layoffs and for other buffer stocks are jointly determined elements of long run technology the choice among alternative stocks will depend on relative profitabilities and firms may choose to hold stocks of inputs as a substitute for inventory accumulation especially if the costs of varying capacity or of storage are important this reasoning implies that i the structure of short run employment and layoff decisions will vary across firms and industries and ii differences in these structures will be systematically related to the role of inventories in firms dynamic strategies some perspective is warranted at least since charles holt et al 1960 economists have recognized the production smoothing role of inventories and the necessity of predicting future demand in making current decisions david belsley 1969 gerald childs 1967 michael ward 1978 similarly one of the contributions of recent work on implicit labor contracts is in viewing the exchange of labor services as a bilateral and durable commitment both these lines of analysis are concerned with the methods firms use to respond to fluctuating demand yet the underlying interrelated nature of employment and inventory decisions has rarely been recognized roger miller 1968 m ishaq nadiri and sherwin rosen 1973 r g crawford 1979 robert hall 1972 this paper aims to provide a framework for evaluating these decisions and in so doing to explain some interesting features of observed labor markets the notion of substitution between inventories of human and physical capital suggests a more disaggregated look at the data table 2 shows the importance of temporary layoffs in the distribution of unemployment among manufacturing industries it reports layoff and total unemployment rates for twelve representative industries over the period 197376 and average layoff rates and recall frequencies for 1958 76 among all 21 twodigit manufacturing industries the correlation between layoff and rehire rates is 6 and the table illustrates this evidently industries with larger than normal layoff rates also tend to have larger rehire frequencies from firm initiated spells of unemployment this university of chicago i am indebted to gary becker robert cotterman sherwin rosen jose scheinkman michael ward finis welch the managing editor and an anonymous referee for discussions and comments at various stages the usual disclaimer applies

tax reform evaluation using nonparametric methods sweden 1980 1991 this paper evaluates the tax reforms carried out in sweden between 1980 and 1991 we use a recently developed nonparametric labor supply function to account for the behavorial responses of the taxed individuals we decompose the tax reform to study how the separate components influence hours of work tax revenues and income distribution the results indicate that the reform was underfinanced and that the increased indirect taxation and redesigned transfer system almost eliminated the positive effects on hours of work due to the decreased marginal taxes on labor income further we compare the results to the predictions of a parametric estimated labor supply model the responses of the parametric model is almost twice the size of the nonparametric

conditions for efficient tax rates abstract in a standard model of optimal taxation and for a small open economy necessary and sufficient conditions for a tax rate to be efficient are derived those conditions are applied to swedish 1982 data marginal tax rates in sweden 1982 are the highest in the oecd countries but not inefficient as evaluated on the basis of the present model

determination of income production and employment under pollution control an input output approach it can be shown that a variation of the multiplier approach solves the leontief pollution model in a more directly interpretable and computationally efficient manner than the conventional method of directly using the augmented leontief inverse matrix the solution of each endogenous variable of the model can be expressed in terms of the non augmented leontief inverse exogenous variables and two important multipliers the pollution control multiplier and a modified keynesian multiplier modified by pollution control the so called induced effect and the effect of pollution control on a given economy can be separated from the model 6 references 5 footnotes 1 table

nonparametric panel estimation of labor supply in this article we estimate structural labor supply with piecewise linear budgets and nonseparable endogenous unobserved heterogeneity we propose a two stage method to address the endogeneity iss

the trade off between equality and efficiency this paper uses a 1976 microdata base to estimate the marginal cost of reducing income inequality with a policy that has distributional effects similar to the present tax transfer system the analysis uses a simulation methodology in which only the labor supply effects are evaluated other behavioral effects are ignored the most striking finding is that marginal cost is quite high even for modest labor supply elasticities for example in the benchmark case with a weighted average economy wide uncompensated wage elasticity of 0 2 and compensated elasticity of 0 31 the disposable money income of upper income quintiles of households is depressed by 9 51 for each dollar increase in the disposable money income of lower income quintiles when income equivalent values that take account of the value of leisure are compared the marginal cost for this case is estimated to be 3 49

nonwage benefits in a simultaneous model of wages and hours labor supply functions of young females this article argues that the negative relationship between weekly hours worked and the gross hourly wage rate is due to the provision of fringe benefits as the total weekly wage increases employers and employees avoid taxation by substituting wages with nontaxable nonwage benefits i produce a wage that incorporates the benefit effects and estimate the corresponding labor supply elasticities an estimator is presented for the wage hours market locus and the structural labor supply function an empirical application indicates that an estimated negative labor supply elasticity associated with the observed gross wage is reversed when the adjusted wage is employed

dynamic income taxation redistribution and the ratchet effect abstract in this paper we extend the classic optimum linear income tax model to a twice repeated game a utilitarian policy maker decides on the second period tax system on the basis of observed first period behaviour we summarise our findings as follows first the static optimal linear tax results cannot be expected to hold in a dynamic setting second more productive households are likely to mimic the behaviour of less productive households third the optimal dynamic first period tax rate might be negative then income is redistributed from low to high income households fourth if the utility function is well behaved then the optimal dynamic first period tax rate is lower than the optimal static tax rate fifth if the optimal static tax rate separates then the dynamic and the static optimal tax rates coincide sixth if a zero tax rate separates then the optimal dynamic tax rate is positive

piece wise or differentiable budget constraint estimating labour supply function for finnish females various estimation approaches have been used in recent literature to study the effect of nonlinear income taxation on labour supply different techniques and data sets have produced a wide range of income and substitution elasticities in this study we utilize register data provided by the tax authorities this gives us good possibilities to construct detailed budget constraints for each individual in our sample we estimate labour supply function using the piece wise linear budget constraint approach and the differentiable budget constraint approach suggested by macurdy et al 1990 our results support the view that if one is able to mimic the actual budget set closely and if the degree of progression is high then these two methods are likely to produce similar results some sensitivity analysis is also carried out using alternative assumptions concerning the budget sets

progressive taxation redistribution and labor supply the analysis of the effect of progression on labor supply is extended to a model with many consumers the condition for progression to increase labor supply given constant aggregate tax revenue is derived and shown to depend on the income effects resulting from redistribution it is then shown that the optimal linear income tax schedule involves a degree of progression which on the margin does reduce labor supply
