the effect of social security contributions on coverage and wages a gender perspective using a natural experiment from colombia author affiliation andres j vargas andres vargas ttu edu acknowledgment i would like to thank steve trejo dan hamermesh gerald oettinger jacqueline angel dan slesnick adriana kugler stefano farne two anonymous referees and seminar participants at the university of texas at austin the second conference on aging in the americas and texas tech university for their insightful and valuable comments i am also grateful to cesar caballero and alejandra corchuelo from the colombian national department of statistics dane for providing me with the data all remaining errors are mine 1 introductiontheoretically social security contributions are considered a benefit linked payroll tax because of the connection between the taxes paid by or on behalf of each worker and that individual s expected benefits hence with the presence of tax benefits linkages workers receive a higher compensation and the contributions are analogous to a price paid for a privately supplied commodity summers 1989 a general payroll tax on the other hand has no linkage to benefits for the individual taxpayer and therefore carries efficiency costs the benefit linkages of social security contributions depend on the extent to which workers perceive that they are getting the contributions back as benefits and on how much the individual values those benefits this depends in turn on the quality of the services offered by the entities financed by the tax if they are perceived as good employees will consider the contributions as a deferred compensation or insurance program and will accept a reduction in the net wage with no employment effects if they are perceived as bad the contributions will be considered as a pure tax with the corresponding effects on employment kesselman 1997 the objective of this article is to investigate from a gender and marital status perspective the effects of pension and health care contributions on the employment and wages of workers covered by social security regulations it is interesting to study colombia because the country implemented a large social security reform in 1993 that allows the identification the labor market effects of these contributions furthermore payments for pension and health care provisions amount to a quarter of the wage bill there this in conjunction with an 11 average contribution for other payroll taxes positions colombia as the country with the highest payroll tax rate in latin america the end of the 1980s and early 1990s was a period of deep structural transformations in latin america these reforms were part of efforts to liberalize economies and increase the participation of the market in the production and allocation of goods and services and were the product of the collapse most economies in the region experienced during the 1980s due to their mounting fiscal and monetary imbalances heckman and pages 2004 these large exogenous shifts in policy regimes offer very good case studies of the interaction between institutions and labor market outcomes the main reforms in colombia during this period included the approval of a new constitution key reforms to the labor market a major trade reform and liberalization in direct foreign investment more than two years after these reforms were put in place colombia implemented a social security reorganization that transformed the institutional framework for pension funds and health care provision law 100 of december 1993 regarding the health care regime the social security reform replaced the existing discretionary affiliation system that covered only the worker with a mandatory one that features a stricter prepayment system and covers also the family of the worker on the subject of pensions the reform introduced a fully funded social security system and gave the workers the choice between this new scheme of individual capitalization of public funds and the existing pay as you go system

mandate based health reform and the labor market evidence from the massachusetts reform we model the labor market impact of the key provisions of the national and massachusetts mandate based health reforms individual mandates employer mandates and subsidies we characterize the compensating differential for employer sponsored health insurance eshi and the welfare impact of reform in terms of sufficient statistics we compare welfare under mandate based reform to welfare in a counterfactual world where individuals do not value eshi relying on the massachusetts reform we find that jobs with eshi pay 2812 less annually somewhat less than the cost of eshi to employers accordingly the deadweight loss of mandate based health reform was approximately 8 percent of its potential size

a decomposition analysis of the trend in uk income inequality post war britain has experienced a number of dramatic demographic and social changes that have undoubtedly influenced the distribution of income there has been a rise in the number of pensioners whose incomes are relatively low a considerable increase in the number of young and old households living on their own and a remarkable expansion in the proportion of working wives the potential importance of these structural changes suggests that their impact on the income distribution needs to be examined systematically before any attempt can be made to interpret the observed trend in overall income inequality adequately the method usually adopted for this purpose attempts to create a comparable time series of distributions based on the structural characteristics pertaining in one particular year for example if we wished to investigate the effect of shifts in the age structure of the population this approach would disaggregate the distribution in one year tl and estimate what the distribution would have been like if the age structure had been the same as that observed in some other year to on the assumption that other distributional characteristics such as ageincome differentials and inequality within age groups remain invariant to this demographic change the comparison between the actual distribution at t1 and the constructed distribution at t1 with to s age structure is taken to indicate the impact of changes in the age structure over the period concerned this comparison can be presented in terms of quantile shares summary measures of inequality or the entire lorenz curves this approach known as shift share analysis or standardising the inequality series see semple i975 love and wolfson i976 dinwiddy and reed i977 royal commission i977 rowley and henderson i978 macleod and horner i980 is perfectly adequate for simple and straightforward structural changes when several changes are occurring simultaneously however it becomes difficult to identify the contribution of the individual factors and to assess their relative importance to the overall trend in inequality furthermore the combined impact of several structural influences will not in general sum up to the inequality change requiring explanation the purpose of this paper is to propose an alternative method of analysing

measuring returns on investments in collectibles this paper considers the question of how to measure and interpret the financial return to investing in collectibles we review various methodologies for creating priced indexes and then discuss studies that explicitly calculate a rate of return to some set of collectibles while most collectibles appear to yield positive real returns the majority embody more risk and yield lower financial returns than stocks other characteristics of collectibles prices such as covariance with other asset prices are also examined

the effects of firm specific taxes and government mandates with an application to the u s unemployment insurance program abstract we examine the common but unexamined case of a tax or government mandate whose cost differs across firms within the same labor market our theoretical model shows that this variation can lead to employment reallocation across firms and dead weight losses even if there is no aggregate employment effect using firm level unemployment insurance tax data we find that while the market level tax is mostly born by the worker individual firms can only pass on a small share of the within market differences thus in some cases differences in taxes across firms can lead to large dead weight losses

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

two decades of income inequality in britain the role of wages household earnings and redistribution we study earnings and income inequality in britain over the past two decades including the period of relatively inclusive growth from 1997 to 2004 and the great recession we focus on the middle 90 where trends have contrasted strongly with the new inequality at the very top household earnings inequality has risen driven by male earnings although a catch up of female earnings did hold down individual earnings inequality and reduce within household inequality nevertheless net household income inequality fell due to deliberate increases in redistribution the tax and transfer system s insurance role during the great recession falling household worklessness and rising pensioner incomes

has consumption inequality mirrored income inequality we revisit to what extent the increase in income inequality since 1980 was mirrored by consumption inequality we do so by constructing an alternative measure of consumption expenditure using a demand system to correct for systematic measurement error in the consumer expenditure survey our estimation exploits the relative expenditure of high and low income households on luxuries versus necessities this double differencing corrects for measurement error that can vary over time by good and income we find consumption inequality tracked income inequality much more closely than estimated by direct responses on expenditures jel d31 d63 e21

the consequences of the growth of health insurance premiums in the united states two thirds of the nonelderly population is covered by employerprovided health insurance ehi according to a kaiser family foundation national survey 2003 the cost of ehi has increased by over 59 percent since 2000 with no accompanying increase in the scale or scope of benefits these increases in health insurance premiums may have significant effects on labor markets including changes in the number of jobs hours worked per employee wages and compensation packages indeed it is possible that a significant portion of the increase in the uninsured population may be a consequence of employers shedding this benefit as health insurance premiums rise understanding how labor market characteristics affect adjustments to increased health insurance costs is of vital policy importance some proposals to cover the uninsured rely on employer mandates requiring employers to cover eligible workers other proposals provide tax credits for the purchase of non employer health insurance the effects of these proposals on employment wages and health insurance coverage will be driven by the elasticities of labor supply and demand institutional constraints on wages and compensation packages and how much workers value the increase in health insurance costs since employers provide such coverage voluntarily if workers fully value these benefits and are able to sort between firms based on their preferences then in the absence of other institutional constraints they will bear the cost of the increase via reduced wages with no accompanying change in employment employment costs or employee utility there are many reasons to believe however that firms are limited in their ability to offset increases in the price of health insurance premiums through lower compensation so that increases in the cost of providing health insurance may affect both employment and the structure of work identifying the magnitude of these effects empirically is difficult both because of data availability and because of multiple avenues for causality in this paper we uncover the causal effect of increases in the cost of benefits on labor market outcomes by exploiting an exogenous source of variation in the cost of providing health insurance the recent medical malpractice crisis in which malpractice costs for physicians grew dramatically in some states but not in others the growth in malpractice payments affects malpractice insurance premiums and health insurance premiums but it should not affect other aspects of employment see baicker and chandra 2005b using this source of variation we examine the effect of increases in health insurance premiums on employment patterns earnings and health insurance coverage we find that the cost of increases in health insurance premiums is borne in large part by workers through increased unemployment and also through decreased hours for those workers moved from full time jobs with benefits to parttime jobs without these results have strong implications for the distributional impact of health care reforms both authors economics department dartmouth college 6106 rockefeller hall hanover nh 03755 dartmouth medical school and national bureau of economic research e mails kbaicker dartmouth edu achandra dartmouth edu we thank alan garber seth seabury jonathan skinner and douglas staiger for helpful conversations that have influenced this research program and derek neal aaron yelowitz and conference participants at the berger conference for very insightful comments we are grateful for funding from nia p01 ag19783 02 the opinions in this paper are those of the authors and should not be attributed to the nia or nber 1 based on tabulations of population under age 65 from the march current population survey for 1988 2003 2 there is a wide literature estimating the wage fringe trade off a 1 increase in the value of fringes may be offset by a 1 reduction in wages or a 1 1 tax rate reduction for tax favored benefits for example jonathan gruber 1994 demonstrates that the passage of the pregnancy discrimination act in 1978 resulted in employers shifting the entire cost of the mandate onto employees

the labor market effects of rising health insurance premiums we estimate the effect of rising health insurance premiums on wages employment and the distribution of part time and full time work using variation in medical malpractice payments driven by the recent medical malpractice crisis we estimate that a 10 increase in health insurance premiums reduces the aggregate probability of being employed by 1 2 percentage points reduces hours worked by 2 4 and increases the likelihood that a worker is employed only part time by 1 9 percentage points for workers covered by employer provided health insurance this increase in premiums results in an offsetting decrease in wages of 2 3

wage inequality in the labour years this paper studies changes in labour market inequality in the uk with particular reference to what happened to wage inequality during the years of labour government the analysis uses micro data through time to document what happened to overall wage inequality as well as upper and lower tail wage inequality relative to what went before simple supply and demand models of changing wage differentials by education group are used so as to consider the drivers of relative demand shifts in favour of the more educated that underpin rising wage inequality the changing role of labour market institutions is also discussed and in particular the decline of unionization and the importance of the introduction of the national minimum wage in 1999 for the evolution of lower tail wage inequality

pareto models top incomes and recent trends in uk income inequality i determine uk income inequality levels and trends by combining inequality estimates from tax return data for the rich and household survey data for the non rich taking advantage of the better coverage of top incomes in tax return data which i demonstrate and creating income variables in the survey data with the same definitions as in the tax data to enhance comparability for top income recipients i estimate inequality and mean income by fitting pareto models to the tax data examining specification issues in depth notably whether to use pareto i or pareto ii generalized pareto models and the choice of income threshold above which the pareto models apply the preferred specification is a pareto ii model with a threshold set at the 99th or 95th percentile depending on year conclusions about aggregate uk inequality trends since the mid 1990s are robust to the way in which tax data are employed the gini coefficient for individual gross income rose by around 7 or 8 between 1996 7 and 2007 8 with most of the increase occurring after 2003 4 the corresponding estimate based wholly on the survey data is around 5

the distribution of ncome in the uk and oecd countries in the twentieth century distributional changes are an important part of the economic history of the oecd countries over the twentieth century in the uk income inequality in the 1970s was substantially lower than 40 years earlier and is now much higher than in 1979 the pattern of change in the usa has similarities to that in the uk but other countries have exhibited significant differences in order to explain diversity of experience over time and differences in income inequality across countries today we need to recognize that the distribution of income is subject to a variety of forces affecting earnings wealth and income these forces include the policy choices made by governments affecting market incomes and fiscal redistribution what we need to explain is why in some periods a number of these forces combine to produce episodes of rising or falling inequality any single theory such as that based on a global shift of demand away from unskilled workers cannot provide a fully adequate explanation

bankruptcy as implicit health insurance this paper examines the implicit health insurance that households receive from the ability to declare bankruptcy exploiting multiple sources of variation in asset exemption law i show that uninsured households with a greater financial cost of bankruptcy make higher out of pocket medical payments conditional on the amount of care received in turn i find that households with greater wealth at risk are more likely to hold health insurance the implicit insurance from bankruptcy distorts the insurance coverage decision using a microsimulation model i calculate that the optimal pigovian penalties are three quarters as large as the average penalties under the affordable care act

unintended consequences of maternity leave legislation the case of colombia abstract we estimate the impact on female labor outcomes of the extension in maternity leave period from 12 to 14 weeks an amendment to the colombian labor law in 2011 to identify this impact we compare labor market outcomes of different groups of individuals with women of child bearing age first we compared two groups of women with different fertility rates low elasticity of substitution finding that as result of the extension women in the high fertility age group experience an increase in inactivity informality and self employment when comparing high fertility age women with men in the same age group high elasticity of substitution we find that the extension increases the probability of unemployment informality and self employment and decreases wages of women compared with men

income inequality and the labour market in britain and the us abstract we study household income inequality in both great britain and the united states and the interplay between labour market earnings and the tax system while both britain and the us have witnessed secular increases in 90 10 male earnings inequality over the last three decades this measure of inequality in net family income has declined in britain while it has risen in the us to better understand these comparisons we examine the interaction between labour market earnings in the family assortative mating the tax and welfare benefit system and household income inequality we find that both countries have witnessed sizeable changes in employment which have primarily occurred on the extensive margin in the us and on the intensive margin in britain increases in the generosity of the welfare system in britain played a key role in equalizing net income growth across the wage distribution whereas the relatively weak safety net available to non workers in the us mean this growing group has seen particularly adverse developments in their net incomes

measuring the trends in inequality of individuals and families income and consumption we present evidence on the level of and trend in inequality from 1985 2010 in the united states using disposable income and consumption for a sample of individuals from the consumer expenditure ce survey differing from the findings in other recent research we find that the trends in income and consumption inequality are broadly similar between 1985 and 2006 but diverge during the great recession with consumption inequality decreasing and income inequality increasing given the differences in the trends in inequality in the last four years using both income and consumption provides useful information

the economic consequences of parental leave mandates lessons from europe this study investigates the economic consequences of rights to paid parental leave in nine european countries over the 1969 through 1993 period since women use virtually all parental leave in most nations men constitute a reasonable comparison group and most of the analysis examines how changes in paid leave affect the gap between female and male labor market outcomes the employment to populations ratios of women in their prime childbearing years are also compared with those of corresponding aged men and older females parental leave is associated with increases in women s employment but with reductions in their relative wages at extended durations

who pays for public employee health costs abstract we analyze the incidence of public employee health benefits because these benefits are negotiated through the political process relevant labor market institutions deviate significantly from the competitive private sector benchmark empirically we find that roughly 15 percent of the cost of recent benefit growth was passed onto school district employees through reductions in wages and salaries strong teachers unions were associated with relatively strong linkages between benefit growth and growth in total compensation our analysis is consistent with the view that the costs of public workers benefits are difficult to monitor contributing to benefit oriented and often under funded compensation schemes

extreme wage inequality pay at the very top we provide new evidence on the growth in pay at the very top of the wage distribution in the united kingdom sectoral decompositions show that workers in the financial sector have accounted for the majority of the gains at the top over the last decade new results are also presented on the pay of ceos in the united kingdom we show how improved measurement of pay points to a stronger pay performance link than previously estimated this link is stronger and more symmetric for those firms in which institutional investors play a larger role

consumption inequality and family labor supply we examine the link between wage and consumption inequality using a life cycle model incorporating consumption and family labor supply decisions we derive analytical expressions for the dynamics of consumption hours and earnings of two earners in the presence of correlated wage shocks nonseparability progressive taxation and asset accumulation the model is estimated using panel data for hours earnings assets and consumption we focus on family labor supply as an insurance mechanism and find strong evidence of smoothing of permanent wage shocks once family labor supply assets and taxes are properly accounted for there is little evidence of additional insurance jel d12 d14 d91 j22 j31

automatic stabilizers and economic crisis us vs europe this paper analyzes the effectiveness of the tax and transfer systems in the eu and the us to provide income insurance through automatic stabilization in the recent economic crisis we find that automatic stabilizers absorb 38 of a proportional income shock in the eu compared to 32 in the us in the case of an unemployment shock 47 of the shock is absorbed in the eu compared to 34 in the us this cushioning of disposable income leads to a demand stabilization of up to 30 in the eu and up to 20 in the us there is large heterogeneity within the eu automatic stabilizers in eastern and southern europe are much lower than in central and northern european countries we also investigate whether countries with weak automatic stabilizers have enacted larger fiscal stimulus programs

workers should want to pay more for social security i introduction although economic theory cannot resolve all the controversies concerning social security simple supply and demand analysis can helpfully change the terms of the debate concerned with how the social security tax is divided between employers and workers defenders of the existing system typically argue that workers pay only half the tax 6 2 because as required by law the other half is paid by employers opponents of the existing system typically argue that workers pay all of the social security tax because their compensation is reduced by employers to offset their portion of the tax for example former house majority leader dick armey 2005 states that social security alone takes 12 4 percent of workers incomes that s more than most workers pay in income taxes in a reply to armey marilyn scheiner 2005 states that armey should have said that social security alone takes 6 2 percent of workers income the employer matches the employee s contribution for a total of 12 4 percent going into the social security coffers 1 the first thing economic analysis tells us about this debate is that both sides are wrong on the facts barring unlikely conditions the second and more interesting insight is that each side of the debate is making a claim that supports the position of the other side any student in an economic principles course should know that the distribution of a payroll tax burden depends on the relative elasticities of the labor demand and supply curves if the labor supply curve is very inelastic relative to the labor demand curve then most of the burden of a payroll tax will fall on the workers on the other hand if the labor demand curve is very inelastic relative to the labor supply curve most of the burden will fall on the employer so the debate over who bears most of the cost of the social security tax has to consider the relative elasticities of labor supply and demand what the social security legislation states about the distribution of the tax burden is completely irrelevant 2 this may seem to suggest that the opponents supporters of social security should argue that labor supply is less more elastic than labor demand because this implies that less most of the tax burden is borne by the employer but why should the desirability of social security depend on the distribution of the tax burden supposedly there are benefits from social security so its desirability should depend on how those benefits compare to the tax and how the net benefits are distributed even though labor supply and demand elasticities are relevant to the distribution of gains or losses from social security we shall see that the desirability of social security as measured by its net value and its benefits to workers is completely independent of those elasticities once we take into consideration the benefits of social security we find that when advocates and opponents argue over the incidence of the tax they have their arguments completely backward the strongest argument in favor of social security is that workers are paying more than its cost on the other hand the strongest argument against social security is that the burden of financing it falls mostly on employers if employers are paying most of the cost of social security then for the sake of workers it should be scrapped immediately ii social security and shifts in the labor supply and demand curves our argument is based on straightforward implications of labor supply and demand curves shifts in response to the costs and benefits of social security 3 we begin in figure 1 with labor supply curve s and labor demand curve d assumed relevant without before social security the vertical axis represents the monetary wage and the horizontal axis represents the quantity of labor the equilibrium wage and labor quantity are given by w sub b and l sub b respectively

accounting for inequality trends decomposition analyses for the uk 1971 86 eight explanations for uk income inequality trends between 1971 and 1986 are assessed by pooling evidence from inequality index decompositions by population sub group and by income source the principal causes of the aggregate trends were a mixture of changes in earnings inequality employment structure and unemployment but this mixture changed over time the impact of wage inequality changes on income inequality changes fell during the 1970s and 1980s reflecting the secular decline in the importance of employment earnings for household income packages unemployment changes had their largest impact at the start of the 1980s between 1981 and 1986 self employment income changes appear to have had the largest influence

consumption and income inequality and the great recession abstract we examine changes in consumption and income inequality between 2000 and 2011 during the most recent recession unemployment rose and asset values declined sharply we investigate how the recession affected inequality while addressing concerns about underreporting in consumption data income inequality rose throughout the period from 2000 to 2011 the 90 10 ratio was 19 percent higher at the end of this period than at the beginning in contrast consumption inequality rose during the first half of this period but then fell after 2005 by 2011 the 90 10 ratio for consumption was slightly lower than it was in 2000

zero hours contracts and labour market policy the evolving nature of atypical work arrangements is studied a particular focus is placed on one such form of work relation zero hour contracts zhcs the paper uses existing secondary data and new survey data collected for the specific purpose of studying alternative work arrangements to describe the nature of zhc work in the uk labour market the interaction with labour market policy is explored in the context of the 2016 introduction of the uk s national living wage zhc work is shown to be an important feature of today s work arrangements and the wage cost shock induced by the new higher minimum wage resulted in an increased use of zhcs in the uk social care sector and in low wage sectors more generally

does aid matter measuring the effect of student aid on college attendance and completion does student aid increase college attendance or simply subsidize costs for infra marginal students settling the question empirically is a challenge because aid is correlated with many characteristics that influence educational investment decisions a shift in financial aid policy that affects some youth but not others can provide an identifying source of variation in aid in 1982 congress eliminated the social security student benefit program which at its peak provided grants totaling 3 7 billion a year to one out of ten college students using the death of a parent as a proxy for social security beneficiary status i find that offering 1 000 1998 of grant aid increases educational attainment by about 0 16 years and the probability of attending college by four percentage points the elasticities of attendance and completed years of college with respect to schooling costs are 0 7 to 0 8 the evidence suggests that aid has a threshold effect a student who has crossed the hurdle of college entry with the assistance of aid is more likely to continue schooling later in life than one who has never attempted college this is consistent with a model in which there are fixed costs of college entry finally a cost benefit analysis indicates that the aid program examined by this paper was a cost effective use of government resources this abstract was borrowed from another version of this item

nondisclosure as a contract remedy explaining the advance notice puzzle prior theoretical work predicts an underprovision of advance notice contracts stemming from their enforcement costs in the present model it is rather the fundamental inability of workers to alienate their right to quit taken in conjunction with parameters central to job separation decisions that jointly determine the mix of notice and no notice contracts observed in equilibrium not all equilibrium contracts are efficient but there is no underprovision of notice mandating notice cannot improve on joint value and indeed may reduce it furthermore although a mandate can be merely redistributive there are cases in which it harms all parties

the family gap for young women in the united states and britain can maternity leave make a difference in the united states and britain there is a family gap between the wages of mothers and other women differential returns to marital and parental status explain 40 50 of the gender gap another 30 40 is explained by women s lower levels of work experience and lower returns to experience taking advantage of quasi experiments in job protected maternity leave in the united states and britain this article finds that women who had leave coverage and returned to work after childbirth received a wage premium that offset the negative wage effects of children

medical care costs how much welfare loss hardly a week goes by without a front page newspaper article on rising health care costs and the uninsured in this article i focus mainly on costs arguing that the issue has been somewhat misconceived while the level of medical care spending in the u s is a cause for concern the welfare losses associated with rises in that level of spending may not be as large as the public rhetoric can make them seem in fact cost containment may not be as urgent as is widely supposed and some proposed cost containment policies may result in welfare losses for the insured and even increase the number of uninsured

the changing role of government in financing health care an international perspective this paper explores the changing role of government involvement in health care financing policy outside the united states it provides a review of the economics literature in this area to elucidate the implications of recent policy changes on efficiency costs and quality our review reveals that there has been some convergence in policies adopted across countries to improve financing incentives and encourage efficient use of health services in the case of risk pooling all countries with competing pools experience similar difficulties with selection and are adopting more sophisticated forms of risk adjustment in the case of hospital competition the key drivers of success appear to be what is competed on and measurable rather than whether the system is public or private in the case of both the success of performance related pay for providers and issues resulting from wait times evidence differs within and across jurisdictions however the evidence does suggest that some governments have effectively reduced wait times when they have chosen explicitly to focus on achieving this goal many countries are exploring new ways of generating revenues for health care to enable them to cope with significant cost growth but there is little evidence to suggest that collection mechanisms alone are effective in managing the cost or quality of care jel h51 i11 i18

infertility insurance mandates and fertility infertility is considered by the medical community to be a disease of the reproductive system it currently affects over 6 million individuals and one in ten couples cannot conceive without medical assistance the psychological effects of infertility have been compared to the effects of other diseases such as cancer and heart disease e g anne t fidler and judith bernstein 1999 and the financial costs of treatment can be quite large however only 25 percent of all health plan sponsors provide coverage for infertility services in response to a perceived need for coverage legislation was introduced at the federal level in 2003 that would require health plans to provide infertility benefits as the fraction of the population affected by infertility continues to rise there are likely to be continued efforts to mandate coverage understanding the costs and benefits of these policies thus becomes increasingly important the first component of a full analysis is to determine whether these mandates will actually have an effect on fertility by reducing the price of infertility treatment one might expect to see an increase in utilization of treatments this could be true if the mandate expands access to individuals who previously could not afford treatment or if individuals who were previously receiving treatment now choose to consume higher quantities or a higher quality of treatment however it is also possible that these mandates have no effect on access or on treatment consumed but simply provide windfall gains to those individuals who would have purchased treatment in the absence of insurance coverage finally mandates may also have dynamic effects on the timing of births individuals could seek treatment earlier which is beneficial from a medical perspective alternatively individuals could further delay childbearing with the knowledge that they will ultimately be covered in this paper i ask the first order question of whether the mandated insurance coverage of infertility treatment has affected birth rates as of 2003 15 states have enacted some form of infertility insurance mandate using a differencein differences approach i exploit variation in the enactment of mandates both across states and over time and identify control groups that should not have been affected by infertility coverage my results suggest that the mandates increase firstbirth rates for women over age 35 by 32 percent

reimbursing health plans and health providers efficiency in production versus selection the tradeoff between an insurer s or medical provider s incentives to select good risks and to produce efficiently is governed by the supply price analog to the demand price tradeoff between moral hazard and risk aversion under a variety of models the optimum supply price is a mixture of capitation and fee for service payments empirical literature shows that pure capitation payment leaves strong incentives for selection that are acted upon the presence of contracting costs in a rothschild stiglitz model means a limited pooling equilibrium can exist and that poor risks will not be at their preferred outcome

rising inequality changes in the distribution of income and consumption in the 1980s this paper examines changes in the distribution of income and consumption in the united states during the 1980s using data from the current population survey income and consumer expenditure survey consumption we reach three primary conclusions first changes in the distribution of consumption parallel changes in the distribution of income the lowest quintile of the consumption distribution received 0 9 percentage points less of total consumption in 1988 than in 1980 the corresponding decline for income was 0 6 percentage points second broad conclusions concerning recent changes in the consumption distribution are not very sensitive to the exact choice of a measure of family needs under a wide variety of alternative household equivalence scales there is a widening in the consumption distribution in the 1980s third the usc of consumption measures of well being in place of measures based on current money income docs change conclusions concerning the extent of poverty in the united stales using the official federal poverty thresholds we find that the overall consumption poverty rate was three percentage points below the income poverty rate in 1988 comparisons of the poverty rates of the elderly and the non elderly are substantially affected by the choice of poverty measure the consumption poverty rare for the elderly was only 60 percent of the rate for adults and one third of the rate for children in 1988 this abstract was borrowed from another version of this item

the costs of wrongful discharge laws we estimate the effects on employment and wages of wrongful discharge protections adopted by u s state courts during the last three decades we find robust evidence that one wrongful discharge doctrine the implied contract exception reduced state employment rates by 0 8 to 1 7 the initial impact is largest for female and less educated workers those who change jobs frequently while the longer term effect is greater for older and more educated workers those most likely to litigate by contrast we find no robust employment or wage effects of two other widely recognized wrongful discharge laws the public policy and good faith exceptions i introduction w hat is the price of protection this paper estimates the social costs in possibly lower employment and wages of common law protections designed to protect american workers from wrongful discharge economic the ory suggests that employment protection is a double edged sword it provides employment security to incumbent work ers but makes employers reluctant to hire leading to a less flexible labor market with potentially lower employment and wages it is frequently argued that the stagnant employment performance of many european economies during the 1980s and 1990s eurosclerosis can be attributed in part to the significant employment protection given european workers see lazear 1990 and blanchard and wolfers 1999 krueger and pischke 1998 provide a contrasting view among the obstacles to testing this hypothesis is the difficulty of making reliable inferences using cross country comparisons in this paper we study the effects of employment protec tion in the united states numerous scholars have examined the effects of american federal employment laws on em ployment and unemployment acemoglu and angrist 2001 deleire 2000 and jolls and prescott 2004 present evidence that the americans with disabilities act ada decreased employment of disabled persons oyer and schaefer 2000 2002 conclude that the federal civil rights act of 1991 increased the frequency of mass layoffs and raised the returns to experience for workers who have a downward sloping age litigation profile hahn todd and van der klaauw 2001 also evaluate the costs of federal antidiscrimination laws a major hurdle for each of these studies is that these federal statutes apply all at once to the entire country this makes it difficult to separate the effects of the statute from all other changes occurring simulta neously cf donohue 1998 donohue and heckman

customer racial discrimination in the market for memorabilia the case of baseball because consumer discrimination can reduce productivity it is often impossible to tell whether differential productivity is the effect of discrimination or of differential ability detailed data for the sports labor market make it possible to separate consumer discrimination from ability we use a unique approach to determine whether the entertainment value of baseball players is related to their race we examine whether race directly affects the value of a player in the market for baseball cards in contrast to studies that use salaries there is no room for owner or coworker discrimination our evidence supports the hypothesis of consumer discrimination

who pays the high health costs of older workers evidence from prostate cancer screening mandates between 1992 and 2009 30 us states adopted laws mandating that health insurance plans cover screenings for prostate cancer because prostate cancer screenings are used almost exclusively by men over age 50 these mandates raise the cost of insuring older men relative to other groups this article uses a triple difference empirical strategy to take advantage of this quasi random natural experiment in raising the cost of employing older workers using integrated public use microdata series data from the march supplement of the current population survey i find that the increased cost of insuring older workers results in their receiving 2 8 lower hourly wages being 2 less likely to be employed and being 0 7 less likely to have employer sponsored health insurance

the impact of protective measures for female workers policies designed to protect female workers have controversial effects on labor market outcomes both in theory and in practice the analysis uses repeated cross sections of household survey data for taiwan to estimate the impact of working hours restrictions and maternity benefits differential coverage across industrial sectors and demographic groups provides a unique opportunity to identify the impact of both policies in a single natural experiment framework while working hours restrictions have a negative impact on women s actual hours worked and employment maternity benefits increase these labor inputs implying that women value the opportunity to return to jobs they might otherwise have to leave

state mandated benefits and employer provided health insurance abstract one popular explanation for the low rate of employee health insurance coverage is the presence of numerous state regulations which mandate that group health insurance plans must include certain benefits by raising the minimum cost of providing any health insurance coverage these mandated benefits make it impossible for firms which would have desired to offer minimal health insurance at a low cost to do so i use data on insurance coverage among employees in small firms to investigate whether this problem is an important cause of employee non insurance i find that mandates have little effect on the rate of insurance coverage this finding is robust to a variety of specifications of the regulations i also find that this lack of an effect may be because mandates are not binding since most firms appear to offer these benefits even in the absence of regulation

employment effects of payroll taxes an empirical test for germany this study tests to what degree the incidence of payroll taxes in germany is on employment and whether in consequence payroll taxes in particular social insurance contributions are the culprit behind the growing unemployment problem using industry level data for 18 years 1977 1994 a system of five dynamic factor demand equations is estimated various simulations indicate that the employment effects of payroll taxes are minimal

death effect on collectible prices it has been widely observed that the price of art or celebrity memorabilia rises around the time of the artist or figure s death previous authors attribute this death effect primarily to expectations on the part of collectors concerning the future supply of collectibles relating to the public figure as in the case of a durable goods monopolist the observations of the sports memorabilia market suggest that the increase in prices is instead due to a nostalgia effect as a result of the media attention that surrounds the death of a prominent public figure

the incidence of mandated maternity benefits i consider the labor market effects of mandates which raise the costs of employing a demographically identifiable group the efficiency of these policies will be largely dependent on the extent to which their costs are shifted to group specific wages i study several state and federal mandates which stipulated that childbirth be covered comprehensively in health insurance plans raising the relative cost of insuring women of childbearing age i find substantial shifting of the costs of these mandates to the wages of the targeted group correspondingly i find little effect on total labor input for that group jel 118 j32 h51 in an era of tight fiscal budget constraints mandating employer provision of workplace benefits to employees is an attractive means for a government to finance its policy agenda consequently in recent years there has been a growth of interest in mandated benefits as a tool of social policy for example the centerpiece of president bill clinton s health care proposal is mandated employer provision of health insurance and more than 20 states have man

flat lining or seething beneath the surface two decades of changing economic inequality in the uk this paper analyses what happened to economic inequalities in the united kingdom in the two decades from 1995 96 in aggregate inequality changes were unremarkable especially by comparison with sharp increases in the 1980s however over the first decade economic outcomes improved across population groups while over the second near stagnation accompanied continuing high inequality we show that the apparent stability of inequality in this period masked the way in which the nature and depth of economic inequalities changed after the economic crisis leading to substantial differences between and within groups defined in different ways pervasively younger adults lost out in the second decade compared to older ones when population groups are defined in other ways such as region housing tenure or ethnicity patterns are more complex but with the worst off in particular groups often being left behind more complex but with the worst off in particular groups often being left behind

empirical determinants of intertemporal choice abstract we provide new evidence on the empirical determinants of intertemporal financial decisions we use an exogenously imposed choice affecting nearly all croatian retirees to study characteristics associated with choosing a larger deferred stream of payments over a smaller more immediate payment individuals are more willing to defer if they have higher incomes and are not liquidity constrained have a longer time horizon because of better health and longer life expectancy and have stronger bequest motives individuals who expect currency devaluation or political risk to reduce the value of future income are more likely to take the earlier income stream

technology and the labour market the assessment this article reviews the evidence on how technology will affect labour markets in advanced democracies over the next 10 15 years in addition to assessing evidence on the impact of technology on the aggregate number of jobs we take a wider view to consider how the digital revolution will affect the quality and composition of jobs how and where we work and whether labour is supplied as part of a larger firm or as a self employed micro entrepreneur this assessment further aims to situate the papers covered in this issue of the oxford review of policy within the broader literature

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

the incidence of payroll taxation evidence from chile i provide new evidence on the incidence of payroll taxation by examining the experience of chile before and after the privatization of its social security system this policy change led to a sharp exogenous reduction in the payroll tax burden on chilean firms on average payroll tax rates fell by 25 over 6 years using data from a census of manufacturing firms i estimate that the incidence of payroll taxation is fully on wages with no effect on employment this finding is robust to a variety of empirical approaches to the problem of measurement error in firm level measures of taxes worker

an experimental test for risk aversion abstract this paper evaluates an experimental method to measure attitudes to risk in individual subjects the method is applied to study the degree of risk aversion of 46 subjects the results lead us to reject a working hypothesis of risk neutrality for such experimental subjects

the death effect in art prices evidence from denmark analysing a panel of paintings by danish painters suggests that the conditional life expectancy of the artist at the time of sale has a negative impact on the sale price this is consistent with the idea that artists share some of the characteristics of durable monopolists and that the aging and ultimately the death of the artist represent acceptable forms of commitment not to overproduce in addition interest in an artist s work begins to wane after their death

top incomes in the long run of history a recent literature has constructed top income shares time series over the long run for more than twenty countries using income tax statistics top incomes represent a small share of the population but a very significant share of total income and total taxes paid hence aggregate economic growth per capita and gini inequality indexes are sensitive to excluding or including top incomes we discuss the estimation methods and issues that arise when constructing top income share series including income definition and comparability over time and across countries tax avoidance and tax evasion we provide a summary of the key empirical findings most countries experience a dramatic drop in top income shares in the first part of the twentieth century in general due to shocks to top capital incomes during the wars and depression shocks top income shares do not recover in the immediate postwar decades however over the last thirty years top income shares have increased substantially in english speaking countries and in india and china but not in continental european countries or japan this increase is due in part to an unprecedented surge in top wage incomes as a result wage income comprises a larger fraction of top incomes than in the past finally we discuss the theoretical and empirical models that have been proposed to account for the facts and the main questions that remain open

heterogeneity and the effect of mental health parity mandates on the labor market health insurance benefit mandates are believed to have adverse effects on the labor market but efforts to document such effects for mental health parity mandates have had limited success i show that one reason for this failure is that the association between parity mandates and labor market outcomes vary with mental distress accounting for this heterogeneity i find adverse labor market effects for non distressed individuals but favorable effects for moderately distressed individuals and individuals with a moderately distressed family member on net i conclude that the mandates are welfare increasing for moderately distressed workers and their families but may be welfare decreasing for non distressed individuals

bankers and their bonuses we analyse the role of financial sector workers in the huge rise of the share of earnings going to those at the very top of the pay distribution in the uk rising bankers bonuses accounted for two thirds of the increase in the share of the top 1 after 1999 surprisingly bankers share of earnings showed no decline between the peak of the financial boom in 2007 and 2011 three years after the global crisis began nor did bankers relative employment position deteriorate over this period we discuss proposed policy responses such as transparency bonus clawbacks numerical bonus targets and tax

rethinking legal taxonomies for the gig economy both tax law and employment law incentivize engagers of labour to structure their workforce as a crowd of self employed micro entrepreneurs recent technological change and the rise of the gig economy have made it easier for agents to respond to these incentives contributing to an increase in self employment in this article we review the evidence on the rise of the gig economy in the uk and lay out a set of key principles to guide the reform of tax and employment law to better enable policy to meet its underlying objectives

technology growth and expenditure growth in health care in the united states health care technology has contributed to rising survival rates yet health care spending relative to gdp has also grown more rapidly than in any other country we develop a model of patient demand and supplier behavior to explain these parallel trends in technology growth and cost growth we show that health care productivity depends on the heterogeneity of treatment effects across patients the shape of the health production function and the cost structure of procedures such as mris with high fixed costs and low marginal costs the model implies a typology of medical technology productivity i highly cost effective home run innovations with little chance of overuse such as anti retroviral therapy for hiv ii treatments highly effective for some but not for all e g stents and iii gray area treatments with uncertain clinical value such as icu days among chronically ill patients not surprisingly countries adopting category i and effective category ii treatments gain the greatest health improvements while countries adopting ineffective category ii and category iii treatments experience the most rapid cost growth ultimately economic and political resistance in the u s to ever rising tax rates will slow cost growth with uncertain effects on technology growth

labor market consequences of state health insurance regulation this study based mainly on the 1989 98 march current population surveys finds that state mandated health insurance benefits and small group health insurance reform had no statistically significant effects on labor market outcomes such as the quantity of work wages and whether an employee worked for a small or large firm the number and type of state mandated health insurance benefits were unrelated to weeks of work wages and the prevalence of private insurance coverage but positively associated with weekly work hours extensive small group health insurance reform was associated with a slight decline in the prevalence of private insurance coverage in small firms and this reform affected both full and part time employees less extensive reforms were not generally related to the prevalence of private insurance coverage overall the authors do not find strong evidence that insurance regulations affected labor market outcomes although they appear to cause a small decrease in private coverage

bringing income distribution in from the cold the title of this presidential address is chosen to highlight the way in which the subject of income distribution has in the past been marginalised for much of this century it has been very much out in the cold there are signs that in the 1990s it is being welcomed back and i shall be referring to recent research but i would like to use this occasion to give further impetus to the re incorporation of income distribution into the main body of economic analysis this abstract was borrowed from another version of this item

the response of wages to protective labor legislation evidence from canada using micro data from the 1986 87 canadian labour market activity survey the author examines the wage effect of laws requiring advance notice of layoffs and in some cases also requiring severance payments to laid off workers the results suggest that incumbent workers protected by advance notice and severance pay laws were able to extract higher wages than were incumbent workers unprotected by such laws there is evidence however that the ultimate wage effect differed by workers union status starting wages of nonunion workers appear to have fallen to offset the subsequent wage increase indicating that nonunion workers may pay for advance notice and severance pay laws whereas union workers who were protected by such laws seem to have been able to exploit their bargaining position to increase their lifetime earnings

who pays for obesity evidence from health insurance benefit mandates is there an obesity externality in the late 1990s and early 2000s many state governments began requiring health insurance plans to cover treatments for diabetes using difference in difference analysis of restricted geocode data from the 1979 national longitudinal survey of youth to compare wages across states with and without diabetes mandates i find that obese people pay for all of their own increased health costs in the form of lower wages rather than passing them on to employers insurers and co workers

adverse selection and an individual mandate when theory meets practice we develop a model of selection that incorporates a key element of recent health reforms an individual mandate using data from massachusetts we estimate the parameters of the model in the individual market for health insurance we find that premiums and average costs decreased significantly in response to the individual mandate we find an annual welfare gain of 4 1 per person or 51 1 million annually in massachusetts as a result of the reduction in adverse selection we also find smaller post reform markups

the effects of expanding the generosity of the statutory sickness insurance system summary this article evaluates an expansion of employer mandated sick leave from 80 to 100 of forgone gross wages in germany we employ and compare parametric difference in difference did matching did and mixed approaches overall workplace absences increased by at least 10 or 1 day per worker per year we show that taking partial compliance into account increases coefficient estimates further heterogeneity in response behavior was of great importance there is no evidence that the increase in sick leave improved employee health a finding that supports a shirking explanation finally we provide evidence on potential labor market adjustments to the reform copyright 2013 john wiley sons ltd

health insurance market reform and employee compensation the case of pure community rating in new york abstract pure community rating which was enacted to improve access to health insurance in new york s small group market in 1993 prevents carriers from charging different premiums based on the ages of a firm s workers if small firms were adjusting compensation packages prior to reform to offset higher health care costs of older workers then community rating could lead to greater relative wages for older workers post reform and not necessarily induce adverse selection that results in changes in who is insured i present evidence showing that relative wages of older workers in small firms increased in comparison with other states and with large firms within new york following reform

pension reform and gender gaps in latin america what are the policy options abstract several latin american countries have implemented structural reforms in their social security pension systems these reforms have modified the traditional public pay as you go defined benefit payg db schemes introducing multipillar systems where fully funded defined contribution ff dc schemes play an important role gender gaps in coverage and benefits under pagy db and ff dc schemes have been one of the policy issues missing in most of the reforms in part because it has been certainly underresearched in the literature this paper studies the sources of pension gender gaps and provides the pros and cons of a set of policy options that may contribute to overcoming the gaps found in both schemes these policies are divided on the one hand into specific policies that directly affect the determination of pension benefits by modifying formula design or eligibility conditions and on the other hand policies that indirectly affect the level of benefits and the likelihood of being entitled to them by changing incentives in labor market conditions
