what is the optimal immigration policy migration jobs and welfare abstract we study the immigration policy that maximizes the welfare of the native population in an economy where the government designs an optimal redistributive welfare system and supplies public goods we show that when the government can design different tax systems for immigrants and natives free immigration is optimal it is also optimal to use the tax system to encourage the immigration of high skill workers and discourage that of low skill workers when immigrants and natives must be treated alike banning low skill immigration and allowing free immigration for high skill workers is optimal however there might be no high skill immigration when heavy taxes are levied on all high skill workers both natives and immigrants

selection investment and women s relative wages over time in theory growing wage inequality within gender should cause women to invest more in their market productivity and should differentially pull able women into the workforce our paper uses heckman s two step estimator and identification at infinity on repeated current population survey cross sections to calculate relative wage series for women since 1970 that hold constant the composition of skills we find that selection into the female full time full year workforce shifted from negative in the 1970s to positive in the 1990s and that the majority of the apparent narrowing of the gender wage gap reflects changes in female workforce composition we find the same types of composition changes by measuring husbands wages and national longitudinal survey iq data as proxies for unobserved skills our findings help to explain why growing wage equality between genders coincided with growing inequality within gender

measuring human capital in the labor market the supply of experience in 8 oecd countries abstract to investigate the evolution of the supply side of the labor market i derive a methodology to measure an important component of the human capital level of the workforce the experience of the labor market based on the perpetual inventory method a stock of experience is estimated for eight oecd countries it appears that during the last three decades the oecd labor markets have faced a decline in the supply of experience by the labor market participants with a minimum in the early 1980s for most countries and a recovery in the 1990s some implications regarding relative wages relative unemployment and schooling are discussed

the transition to the knowledge economy labor market institutions and income inequality in advanced democracies the transition from fordism to the knowledge economy in the world s advanced democracies was underpinned by the revolution in information and communications technology ict the introduction and rapid diffusion of ict pushed up wages for college educated workers with complementary skills and allowed top managers and ceos to reap greater rewards for their own talents despite these common pressures income inequality did not rise to the same extent everywhere income in the anglo saxon countries remains particularly unequally distributed to shed new light on this puzzle the authors carry out a panel data analysis of eighteen oecd countries between 1970 and 2007 their analysis stands apart from the existing empirical literature by taking a comparative perspective the article examines the extent to which the relationship between the knowledge economy and income inequality is influenced by national labor market institutions the authors find that the expansion of knowledge employment is positively associated with both the 90 10 wage ratio and the income share of the top 1 percent but that these effects are mitigated by the presence of strong labor market institutions such as coordinated wage bargaining strict employment protection legislation high union density and high collective bargaining coverage the authors provide robust evidence against the argument that industrial relations systems are no longer important safeguards of wage solidarity in the knowledge economy

unemployment growth and taxation in industrial countries unemployeement and taxes do taxes affect the rate of umemployeement to the layman the upward trend in european unemployment is related to the slowdown of economic growth we argue that the layman s view is correct the increase in european unemployment and the slowdown in economic growth are related because they stem from a common cause an excessively rapid growth in the cost of labour in europe labour costs have gone up for many reasons but one is particularly easy to identify higher taxes on labour if wages are set by strong and decentralized trade unions an increase in labour taxes is shifted onto higher real wages this has two effects first it reduces labour demand and thus creates unemployment secondly as firms substitute capital for labour the marginal product of capital falls over long periods of time this in turn diminishes the incentive to invest and to grow the data strongly support this view according to our estimates the observed rise of 14 percentage points in labour tax rates between 1965 and 1995 in the eu could account for a rise in eu unemployment of roughly 4 percentage points a reduction of the investment share of output of about 3 percentage points and a growth slowdown of about 0 4 percentage points a year francesco daveri and guido tabellini

the rising skill premium and deunionization abstract during the past 50 years the us economy has seen a rapid decline in labor union membership and a substantial rise in wage inequality since labor unions compress wages between skilled and unskilled workers a rising skill premium encourages skilled workers to withdraw from the union if this withdrawal is accompanied by a fall in the productivity of unskilled workers firms become reluctant to hire the relatively expensive union workers reinforcing the decline in the unionization rate evaluating this hypothesis we find that the rise in the skill premium explains about 40 of the decline in the unionization rate

changes in returns to education in latin america the role of demand and supply of skills using micro data for the urban areas of argentina brazil chile colombia and mexico the authors document trends in men s returns to education during the 1980s and the 1990s and estimate the role of supply and demand factors in explaining the changes in skill premia they propose a model of demand for skills with three production inputs corresponding to workers with primary secondary and university level education further the authors demonstrate that an unprecedented rise in the supply of workers having completed secondary level education depressed their wages relative to workers with primary level education throughout latin america this supply shift was compounded by a generalized shift in the demand for workers with tertiary education

can the scala mobile explain the fall and rise of earnings inequality in italy a semiparametric analysis 1977 1993 this article uses survey of households income and wealth microdata to investigate the role the scala mobile played in the initial fall and subsequent rise in earnings inequality in italy between 1977 and 1993 the scala mobile was a wage indexation mechanism granting the same absolute wage increase to all employees as prices rose thereby potentially compressing wage differentials over time the potential equalizing effect of this mechanism fell this article argues that the rise in inequality from the mid 1980s was a response to the compression of differentials operated over the previous years by the scala mobile

changes in male labor supply and wages in the 1980s both wages and labor supply of poorly educated men fell substantially relative to those of educated men some observers have interpreted this positive association between changes in w

intra firm bargaining under non binding contracts we present a new methodology for studying the problem of intra firm bargaining based on the notion that contracts cannot commit the firm and its agents to wages and employment we develop and analyse a general non cooperative multilateral bargaining framework between the firm and its employees and consider outcomes which are immune to renegotiations by any party equilibrium firm profits are characterizable as both a weighted average of a neo classical non bargaining firm s profits and a generalization of shapley value for a corresponding cooperative game furthermore the resulting payoffs induce economically significant distortions in the firm s input and organizational design decisions

migration theories and evidence an assessment abstract this paper presents a critical survey of theories of migration their welfare and policy implications and their empirical relevance we also develop some extensions to the theory beginning with the harris and todaro ht model in particular the ht model is extended to examine risk averse behaviour within families where the migration of members of families serves to diversify risk the welfare implications of the individual migration decision and government intervention in the form of employment subsidies are examined recent evidence on international migration is presented it is shown that migration does not flow automatically in response to wage differentials characteristics of migrants and the process of self selection are found to be important determinants of the rate of migration

against the wind bargaining recentralisation and wage inequality in norway 1987 91 in the late 1980s norway s labour market experienced similar supply and demand shifts for skills to other countries but unlike other oecd nations norway s wage setting system became more centralised the pay distribution in norway became more compressed at the bottom from 1987 to 1991 while low wage workers in other countries lost ground relatively using norwegian microdata for 1987 and 1991 i found that changing labour market prices helped cause this wage compression further the less educated had declining relative overall employment but increasing relative public sector employment both possible labour market responses to the wage compression

technology and the us labor market evidence from the sectoral and regional decomposition of the change in the us workforce skill mix abstract researchers have found indirect evidence supporting the role of technology in changing the workforce skill mix in the us by decomposing the change in the skill mix into within between industry components this paper provides additional support for the role of technology by extending the decomposition analysis into both the sectoral and the regional dimensions

regional labor markets and the determinants of wage inequality from 1972 to 1990 the united states experienced the largest increase in wage inequality of any developed country the spread in log wages between the 90th and 10th percentiles of the male wage distribution increased by about 60 points and inequality increased within virtually every demographic or skill category of the labor force see chinhui juhn et al 1993 various explanations have been offered including changes in the relative demand for skill intensive goods international trade immigration of less skilled workers and increased labor force participation of women yet attempts to quantify the relative importance of these factors have not met with much success this leaves skill biased technical change as the residual claimant that rationalizes the data this paper uses regional differences in the evolution of wage inequality to provide new evidence on the determinants of relative wages using a model of factor demand in geographic markets i isolate contributions of i changing skill ratios in the labor force ii increased participation of women iii technical change and iv changes in the industrial composition of labor demand the data indicate that changing skill ratios and women s labor supply have affected the wages of low skilled men in the west the data indicate that increased immigration of less skilled hispanic and asian workers has adversely affected the wages of natives causing a greater increase in inequality there than in any other region of the country i modeling wage inequality in regional markets

the welfare state and competitiveness in all industrial countries fiscal policy is increasingly about redistribution in this paper the authors study redistribution across different types of agents in a world characterized by the presence of labor unions and distortionary taxation they show that an increase in transfers financed by distortionary taxation has nonlinear effects on unit labor costs relative to the other countries depending on the degree of centralization of the wage setting process in the labor market the authors find considerable empirical support for the model in a sample of fourteen oecd countries copyright 1997 by american economic association

immigrants minorities and labor market competition this paper investigates the extent of labor market competition among immigrants minorities and the native population an analysis of 1980 u s census data reveals that immigrants tend to be substitutes for some labor market groups and complements for others the effects of shifts in immigrant supply on the earnings of native born men are however very small on the other hand increases in the supply of immigrants do have a sizable impact on the earnings of immigrants themselves an increase of 10 percent in the supply of immigrants for example reduces the immigrant wage by about 10 percent

the effects of minimum wages on employment theory and evidence from britain recent work on the economic effects of minimum wages has stressed that the standard economic model where increases in minimum wages depress employment is not supported by empirical work in some labor markets we present a general theoretical model whereby employers have some degree of monopsony power which allows minimum wages to have the conventional negative impact on employment but which also allows for a neutral or positive impact studying the industry based british wages councils between 1975 and 1992 we find that minimum wages significantly compress the distribution of earnings but do not have a negative impact on employment

the role of shocks and institutions in the rise of european unemployment the aggregate evidence two key facts about european unemployment must be explained the rise in unemployment since the 1960s and the heterogeneity of individual country experiences while adverse shocks can potentially explain much of the rise in unemployment there is insufficient heterogeneity in these shocks to explain cross country differences alternatively while explanations focusing on labour market institutions explain current heterogeneity well many of these institutions pre date the rise in unemployment based on a panel of institutions and shocks for 20 oecd nations since 1960 we find that the interaction between shocks and institutions is crucial to explaining both stylised facts

selected works of michael wallerstein centralized bargaining and wage restraint the literature on corporatism has presented much evidence associating highly centralized systems of collective bargaining with wage restraint and relatively successful macroeconomic performance in addition centralized bargaining is associated with relatively small wage differentials this paper presents a model of the impact of centralized wage setting on both real wages and relative wages the central assumption is that the centralization of wage setting at the national level unites unions who are complements in production since a wage increase for one group of workers negatively affects the welfare of other workers who are complements in production centralized wage setters choose wages below the equilibrium of decentralized wage setting it is also shown that if the union confederation maximizes a utilitarian welfare function with equal weights centralized wage setting decreases wage dispersion while low paid workers clearly gain from centralized bargaining high paid workers may prefer that bargaining be decentralized

when unionization disappears state level unionization and working poverty in the united states although the working poor are a much larger population than the unemployed poor u s poverty research devotes much more attention to joblessness than to working poverty research that does exist o

self employment in the eu quality work precarious work or both this paper estimates the differences in earnings between self employed and employees in the eu using the european union statistics on income and living conditions data and quantile regression methods it finds that in both eastern and western europe self employment pays more than regular employment only for workers at the top of the earnings distribution and considerably less than regular employment for those below the median these differences are smaller in eastern europe reflecting lower protection of regular employees this pattern is not driven by low skilled workers and it can be observed in both high skilled and low skilled occupations results are robust to accounting for differences in taxation hours worked and individual unobserved characteristics the evidence provided points to the lack of protective rights for the self employed and low earnings at the beginning of the self employment spells as the main explanations for lower earnings for the majority of self employed

aids is not a business a study in global corporate responsibility securing access to low cost hiv medications at the end of the 1990s brazil was faced with a potentially explosive hiv aids epidemic through an innovative and multifaceted campaign and despite initial resistance from multinational pharmaceutical companies the government of brazil was able to negotiate price reductions for hiv medications and develop local production capacity thereby averting a public health disaster using interview data and document analysis the authors show that the exercise of corporate social responsibility can be viewed in practice as a dynamic negotiation and an interaction between multiple actors action undertaken in terms of voluntary csr alone may be insufficient this finding highlights the importance of a strong role for national governments and international organizations to pressure companies to perform better

patterns of work across the oecd market work per person of working age differs widely across the oecd countries and there have been some significant changes in the last forty years how to explain this pattern taxes are part of the story but much remains to be explained if we include all the elements of the social security systems like early retirement benefits sickness and disability benefits and unemployment benefits then we can capture some aspects of the overall pattern but still a lot remains unexplained the story favoured by alesina et al cepr dp 5140 2005 is that the nexus of strong unions generous welfare and social democracy implies both high taxes and pressure in favour of work sharing in response to adverse shocks this story however falls foul of the simple fact that most scandinavian countries now do much more work than the french and germans despite having stronger unions more generous welfare higher taxes and more social democracy ultimately we are forced into the position that there is no simple story some of the broad patterns can be explained but there remain country specific factors which are hard to identify but lead to substantial differences from one country to another

the effect of unions on wage inequality in the u s labor market this study uses current population survey micro data for 1973 74 and 1993 to evaluate the effect of changing union membership on trends in male and female wage inequality unionization rates of men fell between the two sample periods with bigger declines among lower skill groups these trends account for 15 20 of the rise in male wage inequality union membership rates of low wage women also declined while unionization increased among higher wage women on balance shifting unionization accounts for very little of the rise in female wage inequality economy wide trends in unionization mask a sharp divergence between the private sector where unionism was declining and the public sector where it was rising comparisons across sectors suggest that unionization substantially slowed the growth in wage inequality in the public sector

capital deepening and wage differentials germany versus us in flexible labour markets capital increases the productivity of skilled workers more than that of unskilled workers and in the us faster investment is associated with wider wage inequality but labour market institutions that keep unskilled workers wages high also imply that firms may find it profitable to invest so as to boost those workers productivity our empirical analysis based on industry level data confirms that a higher capital intensity in germany is associated with smaller wage differentials and with a larger share of unskilled workers in the labour costs changes in capital labour ratios during the 1980s reduced wage differentials by 5 8 in german industries while in the us capital deepening in such industries as machinery and retail was accompanied by an increase of wage differentials larger than 7 winfried koeniger and marco leonardi

economic change and rising income inequality in the oslo region the importance of knowledge intensive business services wessel t economic change and rising income inequality in the oslo region the importance of knowledge intensive business services regional studies the growth of market income inequality in the oslo region of norway between 1993 and 2004 is investigated using two measures it is shown that most of the change occurred within knowledge intensive business services and further within demographic subgroups changes in mean income between group inequality and shifts in the balance between segments of the economy are of minor importance the results support a combined focus on productive paths and institutions labour relations in particular appear as an important explanation however labour relations can hardly explain why men rather than women and western immigrants rather than non western immigrants converge towards employment in high profit businesses this particular pattern requires research beyond the economic and institutional landscape wessel t

do cognitive test scores explain higher u s wage inequality using microdata from the 1994 1998 international adult literacy survey for nine countries we examine the role of cognitive skills in explaining higher wage inequality in the united states we find that while the greater dispersion of cognitive test scores in the united states plays a part in explaining higher u s wage inequality higher labor market prices i e higher returns to measured human capital and cognitive performance and greater residual inequality still play important roles and are on average quantitatively considerably more important than differences in the distribution of test scores in explaining higher u s wage inequality

the implications of wto and gats for the banking sector in africa in this paper we assess the implications of the world trade organisation wto and the general agreement on trade in services gats for the banking sector in african signatory countries with emphasis on the free trade element we first review the relevant provisions of the gats for banking services and the main exemptions held by african countries we then analyse the main efficiency indicators for a sample of the top banks in 18 african economies for the period 1997 1998 we also use univariate statistics to analyse the dispersion of the key bank pricing and liquidity indicators in these economies for the period 1994 1998 the main findings imply that although full liberalization implicit in the wto and gats protocols will lead to a substantial shake up of the african banking industry however provided they have an appropriate regulatory framework and allow sufficient lead time most african countries have little to fear from liberalization at least in terms of the continuing existence of a locally owned banking industry and indeed these countries could reasonably expect to be able to restructure and compete at the very least in african wide or regional markets

the effect of income taxes on household income research on the distribution of income during the 1980s has identified a trend towards increasing inequality which may be the continuation and acceleration of trends spanning several decades this paper explores to what extent behavioral responses to the tax changes during the 1980s may also explain the rising inequality the 1986 tax reform act is used as a natural experiment to explore the roles played by both taxes and a variety of nontax factors our principal finding is that both tax rates and nontax factors appear to have had significant effects on relative income growth during the late 1980s

a comparison of international income inequality an ordered probit model analysis in this study the ordered probit model with marginal effect was applied to examine the key elements that influence changes in the gini levels the empirical results indicated that export incentives and poverty have a positive impact on the gini levels moreover the marginal effect revealed that export incentives increase income inequality for countries with higher inequality and reduce inequality for those countries with a relatively even income distribution likewise the study found that the asian pacific economic cooperation apec and the eu countries move from inequality to equality more efficiently than countries in the latin american integration association laia

benchmarking and transparency incentives for the pharmaceutical industry s corporate social responsibility with over 2 billion people lacking medicines for treatable diseases and 14 million people dying annually from infectious disease there is undeniable need for increased access to medicines there has been an increasing trend to benchmark the pharmaceutical industry on their corporate social responsibility csr performance in access to medicines benchmarking creates a competitive inter business environment and acts as incentive for improving csr this article investigates the corporate feedback discourses pharmaceutical companies make in response to criticisms from benchmarking reports it determines whether these responses are part of a healthy process in increasing access to medicines or a barrier to improvement a qualitative analysis on the feedback the industry provided was performed and the responses seen in these statements were grouped by analysing the language used the ideas portrayed and atti tudes of the companies increasing transparency through benchmarking is a powerful tool which reveals the industry s shortfalls to the public affects the decisions of socially responsible investors and is a risk to their financial bottom line this article demonstrates the importance of benchmarking and transparency in creating inter business competition and the translation of these responses to actual access to medicine practices

gender and the new inequality explaining the college non college wage gap the new inequality is often characterized by the increasing wage gap between workers with a college education and those without yet although the gap in hourly wages between college educated and non college educated women is high and rising the topic has been overshadowed by research on gender inequality and wage inequality among men using the 1990 5 percent public use microdata samples independent sources of macro data and controls for individual human capital characteristics i examine the association between the college non college wage gap and key aspects of local economic conditions for women and men while the college non college wage gap among women is comparable in size to the gap among men significant gender differences emerge in the underlying sources of high wage gaps in over 500 labor markets across the united states compared with men flexible and insecure employment conditions e g joblessness casualization and immigration are more important in fostering high wage gaps among women than are technology trade and industrial composition the prevailing explanations of rising wage inequality over time based on these gender differences i reconsider the debate on labor market restructuring and inequality and discuss a new analytical focus on differences in within gender inequality

corporate responsibilities for access to medicines today there is a growing wave of demands being placed upon the pharmaceutical industry to contribute to improved access to medicines for poor patients in the developing countries 1 this article aims to contribute to the development of a systematic approach and broad consensus about shared benchmarks for good corporate practices in this area a consensus corridor on what constitutes an appropriate portfolio of corporate responsibilities for access to medicines especially under conditions of failing states and market failure 2 is not only in the interest of the world s poor but also of corporations that want to contribute to the solution of one of the most significant social problems of our time

assessing the benefits to developing countries of liberalisation in services trade this paper discusses the potential impacts of services trade liberalisation on developing countries and reviews existing quantitative studies its purpose is to distill themes from current literature rather than to advocate specific policy changes the picture emerging is one of valiant attempts to quantify in the presence of formidable analytical and data problems yielding only a clouded image of likely impacts on trade consumption production and welfare emerging to the point that the policy implications of results are not always clear a central intuition would seem to be that with genuine two sided oecd non oecd liberalisation in services that are seemingly considerably labour intensive in delivery the potential should be there for significant developing country gains from global liberalisation allowing full cross border delivery however this picture is neither fully endorsed by available studies neither is it explicitly contradicted this seems to be the case for a number of reasons one difficulty with the studies is that the conceptual underpinnings of what determines trade in services and how this trade differs analytically from that of trade in goods if at all is an issue prior to assessments of impacts of liberalisation of trade in services on developing countries being discussed key issues here are the treatment of mobility for service providers both firms and workers and the differing analytical structures needed to analyse individual service items banking insurance telecoms etc some recent analytical work suggests that liber alisation in some service items such as banking need not always yield gains and this contrasts with quantitative studies where analytical structures mirror conventional trade in goods treatments the discussion and measurement of barriers to service trade in both developed and developing countries is also problematic one is talking of domestic regulation entry barriers portability of providers competition policy regimes more so than only barriers at national borders as with tariffs both representing and quantifying such barriers raise major difficulties and these are also spelled out in the paper which barriers actually restrict trade and which do not because they are redundant is one issue for instance it is also often misleading to represent barriers in simple ad valorem equivalent form as a result numerical modelling work on the effects of service trade barriers which is based on ad valorem equivalent modelling is often not fully convincing in addition individual country results vary considerably across studies in ways that it is frequently hard for outsiders to understand studies do however point towards a tentative conclusion that effects are small and positive for developed and most developing countries if fdi flow changes accompanying service trade liberalisation are excluded from the analysis but much larger and more variable across countries if they are present this could be taken to suggest that mode 3 gats liberalisation roughly captured in some studies might be important for developing countries but mode 4 gats liberalisation could be even more important given large barriers to labour flows across countries thus if service trade liberalisation is thought of primarily as a surrogate for improved functioning of global factor markets in which more capital flows to developing countries and more labour flows from them to developed countries then developing countries could benefit in a major way from genuine two sided oecd non oecd liberalisation developing countries fear however that in global negotiations on services liberalisation where there is an asymmetry of power that largely one sided liberalisation may be the outcome and their gains will be correspondingly limited the paper concludes by evaluating econometric studies on linkage between services liberalisation and country growth rules and briefly discusses some key sectoral issues in health services and transportation

job security provisions and employment european countries have enacted various job security provisions over the last 30 years employers are required to pay workers on separation or to give advance notice of termination in anything less than a perfectly functioning market there are effects of the provisions on employment incumbents are more likely to retain their jobs but new workers are less likely to be hired an examination of the european data suggests that severance pay requirements reduce employment

public employment and earnings inequality an analysis based on conditional and unconditional quantile regressions studies investigating the link between public employment and earnings inequality based on micro data typically make use of conditional quantile regressions such analysis reveals why earnings may be more or less dispersed among public sector than private sector workers but does not allow drawing conclusions about its impact on overall earnings inequality the unconditional quantile regression technique proposed by firpo et al 2009 overcomes this deficiency and this technique is applied here to show that a fall in public employment may raise or reduce earnings inequality depending on country specificities the paper also highlights the complementary roles of conditional and unconditional quantile regressions in investigating the determinants of earnings inequality

wage setting institutions and pay inequality in advanced industrial societies the distribution of pay differs significantly across countries and over time among advanced industrial societies in this paper institutional and political determinants of pay inequality are studied in sixteen countries from 1980 to 1992 the most important factor in explaining pay dispersion is the level of wage setting i e whether wages are set at the level of the individual the plant the industry or the entire private sector the impact of centralization is the same whether centralization occurs via collective bargaining or via government involvement in private sector wage setting the concentration of unions and the share of the labor force covered by collective bargaining agreements also matter after controlling for wage setting institutions other variables such as the governing coalition the size of government international openness and the supply of highly educated workers have little impact economic political and norm based explanations for the association of centralization with egalitarian outcomes are discussed

overeducation in the labor market this article examines the reasons for the observed discrepancy between workers actual and required levels of schooling and the resulting differences in returns to schooling overeducated workers are found to be younger and to have lower amounts of on the job training than workers with the required level of schooling they also have higher rates of firm and occupational mobility characterized by movement of higher level occupations the findings suggest that overeducation can be explained by the trade off between schooling and other components of human capital and by the mobility patterns of overeducated workers

the decline of welfare benefits in the u s the role of wage inequality welfare benefits in the u s have experienced a much studied secular decline since the mid 1970s we explore a new hypothesis for this decline related to the increase in wage inequality in the labor market and the decline of real wages at the bottom of the distribution we posit that voters prefer benefits which are tied to low skilled wages we test the hypothesis using a 1969 1992 panel of state level data an additional contribution of our analysis is the use of general social survey data on voter preferences for welfare which we combine with current population survey data to determine the voter in each state who has the median preferred welfare benefit level our analysis reveals considerable evidence in support of a role for declining real wages in the decline of welfare benefits

trade liberalization and the inter industry wage premia the missingf role of productivity the literature concerning the effect of tariffs on the inter industry wage premium has not addressed the role of total factor productivity tfp in determining both the wage premium and tariffs this omission not only overlooks an important determinant of wage premium but also invalidates the use of the pre reform tariff level as an instrument for the change in tariffs based on an analysis of colombian data i find that including tfp in the estimated model of the effects of tariffs on the wage premium leads to a 41 decrease in the effect of tariffs on the inter industry wage premium relative to the model that omits tfp more specifically a 10 percentage point decrease in tariffs reduces the wage premium by 1 01 whereas a 10 increase in tfp raise wage premium by 1 6 this finding suggests the importance of using policies that boost productivity to offset the effect of tariffs on the wage premium

the economics of immigration this literature review concerns the impact of immigration on the economy of the host country focusing on the experience of the united states the emphasis is on the period from the 1970s to the 1990s the author shows that research earlier in this period generally concluded that the economic effects of immigration were positive but that more recent research on later migrations have generally concluded that immigration may be having an adverse effect on the earnings of native unskilled workers and be placing an increased burden on welfare programs the importance of such economic analysis for the formulation of appropriate migration policies is stressed

differences in metropolitan and nonmetropolitan u s family income inequality a cross county comparison abstract u s family income inequality is examined using 1990 cenus of population data for the 3109 counties and independent cities in the 48 contiguous states use of counties as the unit of analysis extends previous research on u s income inequality that relied on national state or metropolitan level data in addition including both metropolitan and nonmetropolitan counties allows us to determine whether income inequality differs between them after controlling for a variety of labor market demographic and regional characteristics as another innovation we also consider whether counties that experienced recent structural changes in industry composition have higher income inequality

labor market institutions and wage inequality the authors investigate how labor market institutions such as unemployment insurance unions firing regulations and minimum wages have affected the evolution of wage inequality among male workers results of estimations using data on institutions in eleven oecd countries indicate that changes in labor market institutions can account for much of the change in wage inequality between 1973 and 1998 factors found to have been negatively associated with male wage inequality are union density the strictness of employment protection law unemployment benefit duration unemployment benefit generosity and the size of the minimum wage over the 26 year period institutional changes were associated with a 23 reduction in male wage inequality in france where minimum wages increased and employment protection became stricter but with an increase of up to 11 in the united states and united kingdom where unions became less powerful and in the united states minimum wages fell

ability biased technological transition wage inequality and economic growth thispaper develops a growthmodel characterizedbyability biasedtechnological transition in which the evolution of technology education attainment and wage inequality is consistent with the observed pattern in the united states and other advanced countries over the past several decades it argues that an increase in the rate of technological progress raises the return to ability and simultaneously generates an increase in wage inequality between and within groups of skilled and unskilled workers an increase in average wages of skilled workers a temporary decline in average wages of unskilled workers an increase in education and a productivity transitory slowdown

aggregation bias in elasticities of substitution and the minimum wage paradox while the employment effects of minimum wages are usually reported to be small suggesting low substitutability between skill types direct estimates suggest a much larger degree of substitutability this article argues that this paradox is largely due to a bias induced by the aggregation of skill types into broad categories an assignment model is applied where skilled workers have a comparative advantage in complex jobs the implied pattern of substitutability reveals the sources of the bias estimation results for the united states show elasticities of complementarity to be underestimated by up to a factor 2 5 the methods laid out likewise can be applied to other markets where different quality types are close substitutes such as the housing market

are college graduates more responsive to distant labor market opportunities abstract are highly educated workers better at locating in areas with high labor demand to answer this question i use three decades of u s census data to estimate a mcfadden style model of residential location choice i test for education differentials in the likelihood that young workers reside in states experiencing positive labor demand shocks at the time these workers entered the labor market i find effects of changes in state labor demand on college graduate location choice that are several times greater than for high school graduates nevertheless medium run wage effects of entry labor market conditions for college graduates equal or exceed those of less educated workers

elevating the role of divestment in socially responsible investing the divest movement has focused attention on strategic and ethical differences in the practice of socially responsible investing sri and highlighted an unnecessary bifurcation of best of class engagement and divestment although best of class engagement is favored as a contemporary and pragmatic approach this paper calls for a more pronounced recognition of absolute dealbreakers and divestment as an underpinning for best of class engagement after linking divestment and best of class engagement to their foundations of absolutism and relativism respectively i critique best of class engagement and argue that without a distinct and explicit role for divestment best of class strategies are ethically and strategically fraught following a discussion of which types of issues suggest divestment or best of class engagement i identify the norway government pension fund as a noteworthy example and posit that divestment and engagement are best presented and employed in tandem particularly for issues that have yet to be addressed by law and convention

do minimum wages lead to job losses evidence from oecd countries on low skilled and youth employment the author investigates effects of minimum wage rates on low skilled female low skilled and youth employment the sample consists of 19 organisation for economic co operation and development oec

technological acceleration skill transferability and the rise in residual inequality this paper provides a quantitative theory for the recent rise in residual wage inequality consistent with the empirical observation that a sizable part of this increase has a transitory nature a feature that eludes standard models based on ex ante heterogeneity in ability an acceleration in the rate of quality improvement of equipment like the one observed from the early 1970s increases the productivity quality differentials across machines jobs in a frictional labor market this force translates into higher wage dispersion even among ex ante equal workers with vintage human capital the acceleration reduces workers capacity to transfer skills from old to new machines generating a rise in the cross sectional variance of skills and therefore of wages through calibration the paper shows that this mechanism can account for 30 percent of the surge in residual inequality in the u s economy or for most of its transitory component two key implications of the theory faster within job wage growth and larger wage losses upon displacement find empirical support in the data

factor proportions and relative wages the supply side determinants of wage inequality supply side factors may contribute to rising wage inequality first certain changes in the supply of skills allegedly exacerbate wage inequality women s increased labor force participation and increased immigration are the leading candidates both allegedly reduce the wages of less skilled men however immigration s impact on wage inequality has been minor and the effects of women s participation is inconclusive second in evaluating the likelihood that human capital investment will mitigate future inequality evidence suggests that rising returns to education have increased the proportion of young people attending college limiting the growth of inequality among high wage workers

the decline of labour market institutions and the rise in wage inequality in britain abstract at the same time as the role of labour market institutions declined very dramatically in britain there was a very sharp rise in wage inequality that since 1980 has increased at a faster pace than in most advanced countries britain in the 1980s and early 1990s therefore provides a very good testing ground for evaluating the importance of labour market institutions in explaining the evolution of the wage structure i look at this in terms of two institutions that have traditionally propped up wage levels at the bottom end of the wage distribution unions and minimum wages i find that their weakening has played an important part in the rise in wage inequality in britain

the effect of male wage inequality on female age at first marriage a model in which women search for husbands characterized by their wages predicts increasing within group male wage inequality raises the expected value of continued marital search and so lowers female marriage propensities using 1970 1980 and 1990 census data i test this hypothesis within geographically racially and educationally defined marriage markets the estimates suggest rising male wage inequality accounted for 7 to 18 of the decline in the propensity to marry between 1970 and 1990 for white women and more educated black women growing wage inequality appears to have had little effect on the marriage behavior of less educated black women

labor earnings in one company towns theory and evidence from kazakhstan one company towns characterized by the presence of a large employer in a local labor market are a frequent legacy of state led development strategies how will downsizing or closing unprofitable state owned enterprises affect these towns this article develops a simple model combining monopsony power in the labor market with a keynesian closure of the product market and uses it to interpret the findings of previous studies the article evaluates the impact of the company s employment level on the town s labor earnings in kazakhstan where one company towns are still prevalent the evaluation is based on data from the 1996 living standards measurement survey the results show that labor earnings in the town decrease roughly 1 5 percent when the share of its population working for the company decreases 1 percent the results are robust to changes in the definition of labor earnings and to the inclusion of a variety of other community characteristics in the analysis these results and the theoretical model are combined to evaluate the welfare impact of company downsizing and consequently to derive the optimal extent of labor retrenchment

who benefits from local oil and gas employment labor market composition in the oil and gas industry in texas and the rest of the united states abstract this paper examines local labor market outcomes from an oil and gas boom we examine two main outcomes the probability of employment and the log wages of workers employed outside the oil and gas industry for texas and the rest of the united states across gender race and ethnicity we find that men and women gain employment in the oil and gas industry during booms but such gains are much larger for men and are largest for black and hispanic men we also find positive income spillovers for workers in other industries that are similar in magnitude across demographic groups

explaining international differences in male skill wage differentials by differences in demand and supply of skill this paper explores the hypothesis that wage differentials between skill groups across countries are consistent with a demand and supply framework using micro data from 15 countries we find that about one third of the variation in relative wages between skill groups across countries is explained by differences in net supply of skill groups the demand and supply framework does an even better job at explaining relative wages of low skilled workers

labour market institutions and the personal distribution of income in the oecd we examine what determines differences across countries and over time in the distribution of personal incomes in the oecd we first model the wage determination process and show that unemployment the labour share and the wage differential are all functions of labour market institutions next we show that in a model economy with only four types of agents capitalists skilled and unskilled workers and unemployed the gini coefficient of personal incomes can be expressed as a function of the above three variables labour market institutions hence affect income inequality though the sign of their impact is ambiguous stronger unions and or a more generous unemployment benefit tend to reduce inequality through reduced wage differentials a higher labour share and also higher unemployment we then use a panel of oecd countries for the period 1970 96 to examine these effects we find first that the labour share remains an important aspect of overall inequality patterns and second that stronger unions and a more generous unemployment benefit tend to reduce income inequality high capital labour ratios also emerge as a strong equalising factor which has in part offset the impact of increasing wage inequality on the us distribution of personal incomes

on the political economy of immigration and income redistribution in this article we analyze an economy in which agents vote over immigration policy and redistributive tax policy we show that natives preferences over immigration are influenced by the prospect that immigrants will be voting over future tax policy we also show that changes in the degree of international capital mobility the distribution of initial capital among natives the wealth or poverty of the immigrant pool and the future voting rights and entitlements of immigrants can have dramatic effects on equilibrium immigration and tax policies finally we provide some empirical support for the model s predictions

the corporate social performance financial performance link strategic managers are consistently faced with the decision of how to allocate scarce corporate resources in an environment that is placing more and more pressures on them recent scholarship in strategic management suggests that many of these pressures come directly from sources associated with social issues in management rather than traditional arenas of strategic management using a greatly improved source of data on corporate social performance this paper reports the results of a rigorous study of the empirical linkages between financial and social performance corporate social performance csp is found to be positively associated with prior financial performance supporting the theory that slack resource availability and csp are positively related csp is also found to be positively associated with future financial performance supporting the theory that good management and csp are positively related 1997 by john wiley sons ltd
