welfare effects of distortionary fringe benefits taxation the case of employer provided cars in europe many employees receive company cars as fringe benefits induced by taxation we analyze the welfare effects of company car taxation for the netherlands by estimating to what extent car expenditure and private car travel change when employees receive a company car tax treatment of company cars generates an annual welfare loss ranging from 600 to 780 per company car mainly due to a shift toward more expensive cars from 420 to 600 but also due to increased private travel 180 for the whole of europe the annual welfare loss is about 12 billion 2011 by the economics department of the university of pennsylvania and the osaka university institute of social and economic research association

the tradeoff between wages and employment in trade union objectives this paper demonstrates that contrary to a widely held opinion the determination of the goals of unions is fully amenable to empirical analysis a characterization of the wage and employment setting process in unionized markets is adopted and its qualitative implications examined the first order condition for this model is fitted to time series data on the newspaper industry from ten cities the international typographical union s objective function reveals very restricted opportunities for substituting wages for employment in response to a change in the slope of the employer s labor demand function larger union locals place greater emphasis on wages versus employment than smaller union locals

family welfare cultures strong intergenerational correlations in various types of welfare use have fuelled a long standing debate over whether welfare receipt in one generation causes welfare participation in the next generation some claim a causal relationship in welfare receipt across generations has created a culture in which welfare use reinforces itself through the family others argue the determinants of poverty or poor health are correlated across generations so that children s welfare participation is associated with but not caused by parental welfare receipt however there is little empirical evidence to sort out these claims in this paper we investigate the existence and importance of family welfare cultures in the context of norway s disability insurance di system to overcome the challenge of correlated unobservables across generations we take advantage of random assignment of judges to di applicants whose cases are initially denied some appeal judges are systematically more lenient which leads to random variation in the probability a parent will be allowed di using this exogenous variation we find strong evidence that welfare receipt in one generation causes welfare participation in the next generation when a parent is allowed di their adult child s participation over the next five years increases by 6 percentage points this effect grows over time rising to 12 percentage points after ten years while these findings are specific to our setting they serve to highlight that welfare reforms can have long lasting effects on program participation since any original effect on the current generation could be reinforced by changing the participation behavior of their children as well the detailed nature of our data allows us to compare the intergenerational transmission with spillover effects in other networks and to explore mechanisms our findings point to a special link between parents and their children with little impact due to close neighbors di participation we find suggestive evidence that what may change as a result of a parent being allowed di is their children s beliefs about the efficacy of trying to get on to the di program or their attitudes about di participation and its stigma

works councils and establishment productivity declining union density in many industrialized countries increases interest in alternative forms of employee representation such as works councils the german works council is one of the most powerful forms of worker representation in developed countries but little is known of its causal effect on productivity the author used a large linked employer employee panel data set to examine this issue comparing firms with and without a works council the author finds that establishments with a works council are on average 6 4 more productive but he also presents evidence that this figure underestimates the true productivity effect of works councils

job queues and the union status of workers this paper develops a model of the determination of the union status of workers that allows for the possibility of queuing for union jobs the empirical results derived using a sample from the university of michigan panel study of income dynamics are supportive of the queuing hypothesis the no queue model can be rejected using a likelihood ratio test this suggests that a simple probit or logit model for union status is misspecified because it is not based on any consistent behavioral theory an important implication of the model is that because most new entrants to the labor market prefer union jobs but cannot get them and because accrual of nonunion seniority makes workers progressively less likely to desire union jobs the union status of workers is largely determined by their success in being selected from the queue early in their working life

the joint determination of union status and union wage effects some tests of alternative models the problems of estimation and interpretation of union wage differentials are examined the properties of cross section and longitudinal estimators are compared estimates are presented and those in the literature summarized conflicting results are obtained longitudinal estimators typically produce results smaller than those of ols while cross section methods instrumental variables or inverse mills ratio raise the estimate the paper offers a reconciliation of these results it supports a more optimistic conclusion than that reached in reviews by freeman and lewis who argued that little has been learned from attempts to deal with the endogeneity issue comparisons between estimators are used to throw light on the process governing union status and to suggest interpretations of union differentials consistent with the current evidence

the union nonunion wage differential and monitoring costs abstract this paper presents an efficiency wage explanation of the countercyclical behavior of the union nonunion wage differential and identifies conditions under which unions are more likely to gain such a differential

changes in the international distribution of resources and their impact on u s comparative advantage t he heckscher ohlin h o theory suggests international trade is determined by relative resource supplies among countries prior empirical research such as work on the determinants of u s comparative advantage in a single year has concentrated on the static predictions of h o theory however h o theory also suggests changes over time in resource supplies will alter trade structure the present paper investigates this aspect of h o theory particular emphasis is given to the role of world resource changes as an explanation of changes in u s trade and of the increased international competition in manufactured goods faced by the united states some recent studies have examined the relationship between changes in resource endowments and trade heller 1976 examined changes in the factor content of japan s trade between 1958 and 1968 and found the observed patterns consistent with changes in japan s physical and human capital endowments stern and maskus 1981 investigated changing factor input determinants of u s trade by estimating annual cross section regressions over 1958 77 they suggested u s net exports made less direct use of unskilled labor over time further analysis of the factor content of u s trade suggested increased u s abundance in physical capital relative to human capital between 1958 and 1971 balassa 1979 using a 1970 crosssection of countries concluded that physical and human capital accumulation largely explained changing patterns of comparative advantage in manufactures although these studies made important contributions a number of issues remain concerning the relationship between resources and trade stern and maskus in listing directions for further research cite first an examination of how and why endowments of physical capital human capital and labor have changed within the u s and our major trading partners this paper reports a substantial data effort which addresses this topic another important consideration is that the direct effect of resource endowment variation on trade has yet to be determined previously inferences about the effect of resource endowments on trade have been based primarily on results from industry cross section regressions authors of such work indirectly infer the effect of resource variation on trade by assuming the coefficients from such regressions reflect resource abundance however leamer and bowen 1981 recently demonstrated that signs of coefficients from such regressions need not reflect a country s true resource abundance thus the usual negative coefficient for the capital labor ratio in an analysis of u s trade cannot be used to infer the scarcity of capital and thus cannot be used to infer the effect of an increase in capital endowment on u s trade similarly balassa s procedure of first regressing for each of a sample of countries industry trade on input intensity and then using the estimated coefficients as the dependent variable in a cross country regression on resources is an inappropriate method for inferring the effect of resources on trade this paper advances consideration of these issues by investigating aspects of the relationship between resources and trade section ii examines changing patterns of resource supply among thirty four countries over 1963 75 section iii investigates whether these resource changes are associated with altered comparative advantage in manufactured goods section iv uses cross country regressions to estimate the resource endowment as opposed to factor input determinants of u s manufacturing trade and thereby the direct effect of resource variation on u s trade the received for publication april 23 1981 revision accepted for publication november 30 1982 new york university this paper is an outgrowth of research in bowen 1980a and of further work conducted at ucla under a ford foundation grant directed by edward e leamer an earlier version was presented at the 1980 southern economic association meetings in washington d c comments by c michael aho robert baldwin edward leamer joseph pelzman leo sveikauskas and an anonymous referee are gratefully acknowledged the author remains responsible for errors

the impact of industrial policy on japan s trade specialization recent research has demonstrated the possibility of welfare enhancing industrial policy this paper analyzes the impact of industrial policy on japan s trade pattern and explores the possibility that it has been welfare enhancing econometric results indicate that industrial policies have had an impact on japan s trade specialization these results are obtained contemporaneously and when the explanatory variables are lagged suggesting either that policymakers have been forward looking or that policy interventions have had persistent long lasting effects although some cases of successful targeting are uncovered welfare enhancing interventions appear to have been the exception not the rule copyright 1993 by mit press

uncertainty and optimal social security systems this paper examines the annuity aspect of social security within the framework of an overlapping generations model the duration of life is assumed to be uncertain under a fully funded system demand for social security is determined by each generation so as to maximize expected lifetime utility taking into account the welfare of future generations under a pay as you go system with intergenerational transfers demand for retirement benefits by the working population takes into account taxes paid by descendants it is shown that the two modes of finance are equivalent in terms of all real aggregates effects of changes in expected lifetime and in the birth rate are analyzed starting at the optimal level a compulsory balanced increase in social security taxes and benefits is shown to increase short run savings

economic impacts of new unionization on private sector employers 1984 2001 economic impacts of unionization on employers are difficult to estimate in the absence of large representative data on establishments with union status information estimates are also confounded by selection bias because unions could organize at highly profitable enterprises that are more likely to grow and pay higher wages using multiple establishment level data sets that represent establishments that faced organizing drives in the united states during 1984 1999 this paper uses a regression discontinuity design to estimate the impact of unionization on business survival employment output productivity and wages essentially outcomes for employers where unions barely won the election e g by one vote are compared with those where the unions barely lost the analysis finds small impacts on all outcomes that we examine estimates for wages are close to zero the evidence suggests that at least in recent decades the legal mandate that requires the employer to bargain with a certified union has had little economic impact on employers because unions have been somewhat unsuccessful at securing significant wage gains

efficiency wages monopoly unions and efficient bargaining there are two leading models of wage determination for the unionised sector of the economy the first which is labelled the monopoly model mm by oswald i985 assumes that the union sets the wage and the employer chooses the profit maximising employment level the second which is labelled the efficient bargaining model ebm by oswald i985 notes that both sides can improve on the monopoly outcome by jointly bargaining over wages and employment a key strategy in empirically distinguishing between the two models has been to determine whether the employment wage pair appears to be off the firm s demand curve for labour 1 for example brown and ashenfelter i 986 use the significance of a measure of alternative wages in an employment regression as evidence for the ebm efficiency wages hypotheses in various forms have been used to explain why non union firms might find it profitable to offer wages above marketclearing levels 2 while paying high wages entails direct costs this practice may result in benefits such as high worker effort low turnover or a large supply of labour to the firm one motivation for this literature is to explain involuntary unemployment if the efficiency wage framework is valid then firms may not lower wages even in the face of excess supplies of labour stiglitz i987 an additional motivation of this literature appears to be the empirical observation that interfirm or inter industry wage differentials remain even after most possible economic determinants of these differentials have been controlled krueger and summers i988 further these differentials appear to lower quits and raise the length of queues of job seekers attempting to gain entry they suggest the existence of rents associated with efficiency wages katz and summers i 989 if any version of the efficiency wages story is correct then there are reasons for believing that workers alternative wages will affect employment in the unionised sector even in the absence of efficient bargaining intuition suggests that an identical regression to that proposed by brown and ashenfelter i986 would yield a significant alternative wage in the non union sector of the economy since the marginal revenue product of labour is affected by alternative wages

the union membership wage premium puzzle is there a free rider problem economists have long suggested that labor unions suffer a free rider problem the argument is that since union set wages are available to all workers covered by unions irrespective of their union status and union membership entails costs workers will only join if they are coerced or are offered non wage goods that they value above membership costs yet u s and british empirical research has found a substantial union membership wage premium among private sector union covered workers implying that there is no free rider problem the authors of this study hypothesize that these findings arise due to selectivity problems associated with identifying the union membership effect their analysis which uses rich data from a new linked employer employee survey for britain and exploits the within establishment variation in wages as a function of individual union membership status demonstrates that the apparent wage premium for members is illusory hence a potential free rider problem remains author s abstract free full text download available at http digitalcommons ilr cornell edu ilrreview

comparative advantage in manufactured goods a re appraisal japanese input coefficients are used to investigate the pattern of comparative advantage in the exportation of manufactured products in a cross country framework estimates are made for the imports of manufactured products as well as for net exports also alternative techniques of estimation are utilized and an attempt to explain the residuals in the regression equations and to indicate the predictive power of these equations is made the paper shows that patterns of comparative advantage in manufactured goods can be explained by reference to commodity characteristics and country characteristics in turn intercountry differences in the extent of trade orientation the concentration of exports and foreign direct investment explain part of the residuals of the cross country regression equations finally it has been found that the method applied permits projecting the factor intensity of trade for individual countries

estimating outcome distributions for compliers in instrumental variables models in imbens and ingrist 1994 angrist imbens and rubin 1996 and imbens and rubin 1997 assumptions have been outlined under which instrumental variables estimands can be given a causal interpretation as a local average treatment effect without requiring functional form or constant treatment effect assumptions we extend these results by showing that under these assumptions one can estimate more from the data than the average causal effect for the subpopulation of compliers one can in principle estimate the entire marginal distribution of the outcome under different treatments for this subpopulation these distributions might be useful for a policy maker who wishes to take into account not only differences in average of earnings when contemplating the merits of one job training programme vs another we also show that the standard instrumental variables estimator implicitly estimates these underlying outcome distributions without imposing the required nonnegativity on these implicit density estimates and that imposing non negativity can substantially alter the estimates of the local average treatment effect we illustrate these points by presenting an analysis of the returns to a high school education using quarter of birth as an instrument we show that the standard instrumental variables estimates implicitly estimate the outcome distributions to be negative over a substantial range and that the estimates of the local average treatment effect change considerably when we impose nonnegativity in any of a variety of ways

labour skills and the uk s comparative advantage with its european union partners this paper assesses the extent and sources of the uk comparative advantage within the european union eu it finds that both inter industry and intra industry trade are important despite clear aggregation effects having established that there is a significant degree of inter industry specialization the sources of this are analysed using a factor content approach results are reported for aggregate factors of production and in the case of labour by disaggregated skill categories a key finding is that the uk s net trade with the eu is driven more by a specialization in specific types of skill than by an overall endowment of human capital the results also suggest that the inter industry specialization cannot be explained by comparative advantage alone

firms rents workers bargaining power and the union wage premium this article identifies the wage premium associated with firm level union recognition in france an average premium of 2 is found despite the fact that most workers are already covered by industry level agreements to explore the origin of the premium i construct a simple bargaining model from which i derive three predictions which are tested empirically using matched employer employee data the main prediction is that if intra firm bargaining is behind the union wage premium the latter increases with the amount of quasi rents available in the firms that unions organise this prediction is validated empirically when firms market shares are used as a proxy for their rents

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

competing at home to win abroad evidence from japanese industry the study explores the influence of domestic competition on international trade performance using data from a broad sample of japanese industries domestic rivalry is measured directly using market share instability rather than employing structural variables such as seller concentration we find robust evidence that domestic rivalry has a positive and significant relationship with trade performance measured by world export share particularly when r d intensity reveals opportunities for dynamic improvement and innovation conversely trade protection reduces export performance these findings support the view that local competition not monopoly collusion or a sheltered home market pressures dynamic improvement that leads to international competitiveness

should social security benefits be means tested social security retirement benefits distort the saving decisions of workers who are rational enough to save for their future since the implicit rate of return in an unfunded social security program is less than the marginal product of capital the resulting decline in saving causes a welfare loss the present paper examines the conditions under which the welfare loss could be reduced by replacing the current universal social security program with a means tested program that pays benefits only to those individuals with little or no other retirement income or assets every society must solve the problem of supporting those individuals who become too old to work but have not made adequate provision for their own old age by saving when they were young at the present time the major industrial countries of the world have responded to this problem by creating social security programs that tax the working population and use the proceeds to provide a universal benefit to all retirees regardless of their financial condition this universal provision of social security benefits distorts the saving decisions of those workers who are rational enough to plan for the future since the implicit rate of return that taxpayers get on their this research is part of the nber study of the government budget and the private economy a more complete version of this paper with some numerical calculations is available as nber working paper no 1775 feldstein 1985b i am grateful to gilbert metcalf for assistance with the calculations presented in this paper and for helpful discussions for a discussion of the effect of promised retirement benefits on the savings of employees see feldstein 1974 1982 barro 1974 1978 has discussed an interesting

the general validity of the heckscher ohlin theorem despite a number of attempts to extend it the heckscher ohlin theorem remains woefully restricted in terms of the generality of the assumptions needed for its proof in its traditional form as a statement about the commodity composition of trade the theorem is valid only in the highly abstract environment of the two factor two good twocountry model that has been the mainstay of trade theory for half a century a weaker version of the theorem involving the factor content of trade rather than its commodity composition has been proved for any number of factors goods and countries but this generality has so far been bought only at the cost of other and perhaps equally restrictive assumptions 2 the purpose of this paper is to provide statements and proofs of the heckscher ohlin h o theorem that are more general than those currently available the approach taken is similar to that used in my 1980 article for an extension of the theory of comparative advantage in terms of correlations between autarky prices and trade in section i i lay out the assumptions on which the analysis is based these assumptions provide the outlines of a reasonably general model in which there may be any numbers of goods and factors and in which factor prices may be equalized or not trade impediments in the form of tariffs or export taxes are permitted though transportation costs are not 3 in section ii i discuss the difficulty of inferring the factor content of trade in a world of unequal factor prices and i provide several alternative definitions of that concept for use later in the paper these together with the assumptions of section i are used in section iii to prove a theorem on the value at autarky prices of the factor content of trade in section iv this theorem is used to prove a first corollary that makes a more direct statement about the pattern of trade it says that worldwide there must be a negative correlation between the factor content of trade by factor and country and the corresponding autarky factor prices it is precisely these autarky factor prices that constitute the ohlin measure of factor scarcity therefore the corollary provides a formal statement of the general idea that countries tend to export the services of those factors which they have in relative abundance and it may be regarded as a generalization of the factor content version of the h o theorem finally a generalization of the commodity version of the theorem is proved in section v the concept of a covariance is generalized university of michigan i have benefitted greatly from the comments of paul degrauwe wolfgang mayer michael mussa carl simon and robert stern as well as others who participated in seminars at the universities of michigan chicago and cincinnati and at the national bureau of economic research an anonymous referee also made valuable comments with additional goods and factor price equalization the theorem runs afoul of the indeterminacy of production and trade noted by paul samuelson 1953 and james melvin 1968 without factor price equalization trade impediments and intermediate production can cause reversals of the pattern of trade as shown in my 1979 article if additional factors and countries are also added it becomes difficult even to state the theorem let alone to prove it 2melvin stated such a theorem for the three good two factor case and jaroslav vanek 1968 proved it for the general case but only by assuming factor price equalization trent bertrand 1972 and jon harkness 1979 were able to drop the factor price equalization assumption but replaced it with restrictions on consumption of either goods or factors by country of origin it is unclear to me however that these restrictions can ever be met in a model that is otherwise plausible harkness 1978 has also used the factor content version of the theorems as the motivation for a regression equation relating commodity trade to factor intensities this bears some resemblance to my analysis below in section v see however james anderson 1981 and edward leamer and harry bowen 1981 who have criticized his result with a reply by harkness 1981 3for ease of exposition i do not allow here for transportation costs these were included in an earlier version of this paper following the technique in my 1980 article

an evaluation of factor endowments and protection as determinants of japanese and american foreign trade we consider the relationship between the factor content of japanese and american foreign trade and examine empirically whether discrepancies between the heckscher ohlin theoretical predictions and the observed patterns of trade can be attributed to protection the michigan model of world production and trade is used for computational purposes we find some evidence of discrepancies between predicted and observed trade patterns but removal of protection either worsens these discrepancies or reduces them by only a small amount some possible reasons for the empirical shortcomings of the heckscher ohlin theory are offered in conclusion

union density and varieties of coverage the anatomy of union wage effects in germany collective bargaining in germany takes place at either industry or firm level and bargaining coverage is much higher than union density the share of a firm s employees covered can vary between 0 and 100 suggesting that researchers should distinguish union density coverage at the firm level and coverage at the individual level using linked employer employee data the authors estimate ols and quantile regressions of wages on these dimensions of union influence they find that a higher share of employees in a firm covered by industrywide or firm specific contracts is associated with higher wages but find no clear cut effect on wage dispersion yet holding coverage at the firm level constant individual coverage is associated with lower wages and less wage dispersion higher union density reinforces the effects of coverage but for employees in firms without coverage density s effect is negative and thus compresses the wage distribution in firms without coverage

does collective wage bargaining restore efficiency in a search model with large firms existing search and bargaining models show that firms hire an inefficiently large number of workers we ask whether decentralised collective wage bargaining may result in a second best allocation collective bargaining restores efficiency when the bargained wage is independent of employment conditions that we characterise firms then behave as if collective bargaining was over both wages and employment thus linking the large firm search and bargaining environment to the efficient bargaining model mcdonald and solow 1981 under more realistic conditions workers can bargain for a share of output so that the wage is then a function of employment in equilibrium firms are too large and firm entry is inefficient

commodity trade and relative returns to factors of production in this paper a model that can be used to estimate relative factor price differences between pairs of countries is developed estimation requires observations of actual bilateral commodity trade flows and knowledge of input requirements for commodity production the linchpin here is the set of relative production cost differences which on the one hand determine trade flows and which in turn are a function of production requirements and relative factor returns the model is implemented to estimate relative factor returns between the united states and each of eight other countries several useful applications of the model are suggested

training and union wages abstract this paper investigates whether unions through imposing wage floors that lead to wage compression increase on the job training our analysis focuses on germany based on a model of unions and firm financed training we derive empirical implications regarding apprenticeship training intensity layoffs wage cuts and wage compression in unionized and nonunionized firms we test these implications using firm panel data matched with administrative employee data we find support for the hypothesis that union recognition via imposing minimum wages and wage compression increases training in apprenticeship programs

the eyes of the needles a sequential model of union organizing drives 1999 2004 this paper models three stages of the union organizing drive using a new dataset covering more than 22 000 drives that took place between 1999 and 2004 the correlated sequential model tracks drives through all of their potential stages holding an election winning an election and reaching first contracts only one seventh of organizing drives that filed an election petition with the nlrb managed to reach a first contract within a year of certification the model which controls for the endogeneity of unfair labor practice ulp charges finds that a ulp charge was associated with a 0 smaller cumulative chance of reaching such a contract ulp charges had less effect on the votes cast than on the decision to hold an election and the ability to reach a first contract a sequential model such as this one could be extended to test between some competing theories about the determinants of union organizing

trade liberalization comparative advantage and scale economies stock market evidence from canada abstract the canada united states free trade agreement fta provides an excellent opportunity to analyze the impact of a comprehensive trade liberalization in this paper a stock market event study is employed to capture investors expectations about the consequences of this agreement for manufacturing firms in canada the primary question addressed is whether abnormal stock market returns corresponding to news about the fta are consistent with hypotheses based on comparative advantage and economies of scale the results indicate that both comparative advantage and scale economies played a role in determining investors perceptions of the impact of the fta

the origins of american industrial success 1879 1940 the united states became the world s preeminent manufacturing nation at the turn of the twentieth century this study considers the bases for this success by examining the factor content of trade in manufactured goods surprisingly the most distinctive characteristic of u s manufacturing exports was intensity in nonreproducible natural resources furthermnore this relative intensity was increasing between 1880 and 1920 the study then asks whether resource abundance reflected geological endowment or greater exploitation of geological potential it was mainly the latter jel 042 recent thinking about american economic performance has been marked by alarm over the country s loss of its competitive edge most of this discussion is not rooted in an understanding of the historical origins of the economic leadership now thought to be in jeopardy modern economists tend to assume that the american advantage has been technological and
