any non welfarist method of policy assessment violates the pareto principle reply the public at large many policymakers and a number of economists hold views of social welfare that are non welfarist that is they attach some importance to factors other than the effects of policies on individuals utilities we show however that any non welfarist method of policy assessment violates the pareto principle

predicting how people play games a simple dynamic model of choice we use the simple dynamic model developed in sarin and vahid 1999 games and economic behavior 28 294 309 to explain the experiments reported in erev and roth 1998 american economic review 88 848 881 in an earlier paper sarin and vahid 1998 mimeo texas a m university and monash university we showed that the model predicted behavior in repeated coordination games remarkably well and better than equilibrium theory or reinforcement learning models in this paper we show that the same one parameter model can also explain behavior in games with a unique mixed strategy nash equilibrium better than alternative models hence we obtain further support for the simple dynamic model journal of economic literature classification numbers c7 d8

the ethics of intertemporal distribution in a warming planet this paper evaluates from the ethical viewpoint current work by economists on intergenerational resource allocation in the presence of global warming we begin by attempting to elucidate the debate that has recently occurred on the appropriate choice of the discountrate weofferthreejustificationsformaximizingthediscountedsumofgenerational utilities and find only one of these to be a satisfactory justification of that practice the pos sibility that the human species may become extinct this implies that a very small discount rate large discount factor should be used we argue that the justification for discounting inherent in the approaches taken by many economists is that of the present generation of hegemon which is unacceptable the role of the ramsey equation in deducing the discount rate in these theories is explained as an alternative to discounted utilitarianism we propose a principle of sustainability we describe optimal paths that have been calculated for the sus tainabilitiarian rawlsian objectivefunction andpathsthatwillsustaingrowthinwelfare at a positive rate we report results concerning optimal paths when the uncertainty of existence of future generations is taken into account in sharp contrast to the utilitarian model it turns out that under some conditions the sustainabilitarian can ignore the uncertainty regarding thedateatwhichhumansbecomeextinct thereisastrikingdifferencebetweenthesolutions of the discounted utilitarian program and the sustainabilitarian program under uncertainty

games with unique mixed strategy equilibria an experimental study abstract the results of an experiment studying the choices of subjects playing mixed extensions of three variants of simple 2 2 non constant sum strictly competitive games of the same form matching pennies are presented subjects exhibited a variety of behavioral adaptive learning strategies this heterogeneity of individual behavior produced aggregate dynamics whose estimated steady states are quite different from those predicted by the nash equilibria of those stage games with asymmetrical payoff functions the observed aggregative dynamics are well accounted for both by a quantal equilibrium model of mckelvey and palfrey and by a learning model of roth and erev journal of economic literature classification number c72

efficiency effect of privatization in the developing countries privatization gained considerable momentum in the developing world in the 1980s the motives were many but the hope for higher economic efficiency underlined the expectations of the implementing governments and agencies in the developing countries while the merits of a market based economic system are well established under certain theoretical conditions far less is known of its empirical relevance in the developing world yet to the best of the author s knowledge no empirical study has examined the macro efficiency effect of privatization in the developing countries studies concerned with this issue often limit themselves to the impact of privatization at the firm level for a small number of companies and countries thus the current study is an attempt to provide a systematic quantitative measure of the magnitude of the macroeconomic effect of privatization in 45 developing countries using the concept of frontier production function efficiency differences between developing countries with differ

estimating the effects of a time limited earnings subsidy for welfare leavers in the self sufficiency project ssp welfare demonstration members of a randomly assigned treatment group could receive a subsidy for full time work the subsidy was available for 3 years but only to people who began working full time within 12 months of random assignment a simple optimizing model suggests that the eligibility rules created an establishment incentive to find a job and leave welfare within a year of random assignment and an entitlement incentive to choose work over welfare once eligibility was established building on this insight we develop an econometric model of welfare participation that allows us to separate the two effects and estimate the impact of the earnings subsidy on welfare entry and exit rates among those who achieved eligibility the combination of the two incentives explains the time profile of the experimental impacts which peaked 15 months after random assignment and faded relatively quickly our findings suggest that about half of the peak impact of ssp was attributable to the establishment incentive despite the extra work effort generated by ssp the program had no lasting impact on wages and little or no long run effect on welfare participation

does information matter in the commons experimental evidence abstract common pool resources cprs typically involve interaction where precise information about payoffs is absent however all experimental studies of cprs we are aware of study environments where the payoff structure is known in this paper we address the behavioral consequences of two degrees of information on the mapping between decisions and payoffs we run two treatments one with complete information on the payoff structure and one with none remarkably aggregate behavior is not significantly different between the two treatments in both cases the aggregate tendencies converge to the nash equilibrium furthermore the best reply dynamics organize individual behavior in both treatments remarkably well

an empirical equilibrium job search model with search on the job and heterogeneous workers and firms in this article we present and estimate a synthesis of previous equilibrium search models allowing for continuous distributions of workers opportunity costs of employment as well as firms productivities the model allows for on the job search and we assume that job offer arrival rates for workers are independent of their labor market state we derive the theoretical implications of these assumptions we provide simulations and we develop a semiparametric estimation procedure that we apply to a dataset of individual labor market histories

privatization liberalization wages and employment theory and evidence for the uk most agency based privatization models are of the owner manager relation and ignore the labour market yet in the 1980s there were profound changes in public sector and privatized firms to wages and employment we develop a bargaining model of the manager workforce relation that explains employment and wages when firms are privatized government objectives become more commercial and markets are liberalised using data on 14 uk companies 1972 1988 that were publicly owned in 1972 we find a employment fell following the change to more commercial objectives b wages were only slightly affected by this but fell if the firm lost market power

competition and the racial wage gap evidence from brazil abstract we look at the natural experiment represented by the brazilian trade liberalization from the early 1990s to study the effect of increased competition in the market for final goods on the racial wage gap we focus on local labor markets as the unit of analysis and use the initial structure of employment to calculate the relevant tariff reduction from the perspective of each local labor market we show that the conditional racial wage gap fell more between 1991 and 2000 in regions associated with larger reductions in tariffs or in other words in regions that experienced larger increases in exposure to international competition a reduction in tariffs equivalent to the average observed in the sample was associated with a reduction in the racial wage gap of 18 our results are broadly consistent with theories of employer discrimination that predict that reductions in pure economic rents should lead to reductions in labor market discrimination

heterogeneous treatment and self selection in a wage subsidy experiment abstract the self sufficiency project ssp is a research and demonstration project that offered a generous time limited income supplement to randomly selected welfare applicants under two conditions the first the eligibility condition required that they remain on welfare for at least 12 months the second the qualification condition required that they find a full time job within 12 months after establishing eligibility in this paper we focus on a neglected and important feature of the program namely that the financial reward for becoming qualified is inversely related to the expected wage rate under very simple assumptions we show that those who have a low expected wage rate have a clear incentive to establish eligibility empirical non parametric evidence strongly suggests that individuals self select into eligibility we jointly estimate a participation equation and a wage equation that are correlated through individual random effects our results show that the omission of self selectivity into qualification translates into slightly underestimated treatment effects

payoff assessments without probabilities a simple dynamic model of choice abstract we develop a model which reflects the tendency of people to simplify the decision problems they face the decision maker chooses among alternate strategies only on the basis of the payoff she assesses she would obtain from them and these assessments do not explicitly take into account her subjective judgements regarding the likelihood of alternate states of the world at each stage the decision maker chooses the strategy that she assesses to give the highest payoff she updates her assessments adaptively we show that such behavior leads to maxmin choices we also consider the decision maker who experiences shocks journal of economic literature classification numbers c7 d8

the financial and operating performance of newly privatized firms an international empirical analysis this study compares the pre and postprivatization financial and operating performance of 61 companies from 18 countries and 32 industries that experience full or partial privatization through public share offerings during the period 1961 to 1990 our results document strong performance improvements achieved surprisingly without sacrificing employment security specifically after being privatized firms increase real sales become more profitable increase their capital investment spending improve their operating efficiency and increase their work forces furthermore these companies significantly lower their debt levels and increase dividend payout finally we document significant changes in the size and composition of corporate boards of directors after privatization the last fifteen years have witnessed a significant global shift away from state socialism towards entrepreneurial capitalism one of the most important and visible aspects of this trend has been the enthusiasm with which governments of all political persuasions have sold their state owned enterprises soes to private investors in hopes that the generally unsatisfactory economic performance of these firms can be improved by the discipline of private ownership this denationalization process given its current title of privatization by the conservative government of margaret thatcher in

the effect of piracy on the market penetration of subscription software software piracy is not necessarily harmful to a software firm seeking to launch a new product when strategically managed through the use of price and protection measures piracy establishes the initial adopters of the software who in turn influence other users to buy the product we examine the role of piracy in affecting the adoption of subscription software products we present an individual level model in an adaptive population setting intended to determine the price protection mix that maximizes the discounted profit stream over the life of the software an extension for nonsubscription software is also discussed

prejudice and wages an empirical assessment of becker s the economics of discrimination we test the predictions from becker s 1957 seminal work on employer prejudice and find that relative black wages a vary negatively with the prejudice of the marginal white in a state b vary negatively with the prejudice in the lower tail of the prejudice distribution but are unaffected by the prejudice of the most prejudiced persons in a state and c vary negatively with the fraction of a state that is black our estimates suggest that one quarter of the racial wage gap is due to prejudice with nontrivial consequences for black lifetime earnings

black white earnings differentials privatization versus deregulation over 40 years ago gary becker 1957 argued that competition helps mitigate the ability of firms to engage in wage and employment discrimination deregulated transportation industries in particular provide fertile ground to test the becker hypothesis the increase in competition from deregulation should make it increasingly costly for employers to exercise discriminatory preferences several studies of the deregulated trucking industry provide support for this hypothesis nancy l rose 1987 peoples and lisa saunders 1993 john s heywood and peoples 1994 this study also utilizes information on transportation industries to test the becker hypothesis it differs from the literature in that one of the transportation industries examined is privatized 1 at question is whether the becker hypothesis also holds for a publicly owned transportation industry in a privatized environment this question is addressed by investigating privatization s effect on black white earnings differentials of public transit bus drivers these results are then compared with deregulation s effect on black white earnings differentials of private for hire truck drivers such a comparison allows for analyzing differences in differential earnings for comparable occupations in privatization and deregulation regimes i transportation industries

the impact of deregulation on the employment and wages of airline mechanics this paper describes the effects of deregulation on negotiated wage rates and employment levels of aircraft mechanics in the scheduled airline industry between 1978 and 1984 a firm by firm analysi

the benefits of privatization evidence from mexico critics of privatization often argue that its benefits come at a high cost to society the authors test the validity of this criticism for mexico s privatization program one of the world s largest case by case programs assessing the performance of newly privatized firms in such areas as profitability and efficiency they find that these firms quickly close the gap with their peers in the private sector their findings suggest that the firms profit gains come from productivity gains 52 percent layoffs 33 percent and higher prices 15 percent

trucking deregulation and the black white wage gap the only previous study of the effect of product market deregulation on the black white wage gap found that this gap in the trucking industry declined after trucking deregulation in 1978 that study did not however estimate the separate effects of deregulation on union and nonunion members or on black and white drivers this study does so through an analysis of individual worker information from the march and may cps files for the years 1973 through 1988 the authors find that deregulation is associated with significantly declining black white wage gaps among both union and nonunion drivers this wage pattern is attributable to significant reductions in the real wages of white drivers the real wages of black drivers did not change with deregulation

trade liberalization and regional dynamics abstract we study the evolution of trade liberalization s effects on brazilian local labor markets regions facing larger tariff cuts experienced prolonged declines in formal sector employment and

two criteria for social decisions abstract this paper studies the ethical underpinnings of two social criteria which are prominent in the literature dealing with the problem of evaluating allocations of several consumption goods in a population with heterogenous preferences the pazner schmeidler criterion pazner schmeidler egalitarian equivalent allocations a new concept of economic equity quart j econ 92 1978 671 687 and the egalitarian walras criterion fleurbaey and maniquet utilitarianism versus fairness in welfare economics in m salles j a weymark eds justice political liberalism and utilitarianism themes from harsanyi and rawls cambridge university press cambridge 1996 forthcoming are prima facie quite different but it is shown here that these criteria are related to close variants of the fairness condition that an allocation is better when every individual bundle in it dominates the average consumption in another allocation in addition the results suggest that the pazner schmeidler criterion can be viewed as the best extension of the walrasian criterion to non convex economies

sex discrimination and product market competition the case of the banking industry this paper examines the relationship between product market competition and employment discrimination using an especially constructed data set that links microeconomic data on female employment with measures of market concentration in the banking industry the use of firm specific data drawn from this one industry allows estimation of this relationship in a manner that avoids the problems of interindustry differences that have troubled previous studies the results provide strong support for a negative relationship between market concentration and the relative employment of women further we find that individual market shares are unrelated to female employment suggesting that the relationship is due primarily to differences across markets rather than individual firms

equilibrium play and adaptive learning in a three person centipede game the two person centipede game is one of the most celebrated paradoxes of backward induction in complete information extensive form games an experimental investigation of a three person centipede game shows that the paradoxical results are strongly affected by the size of the stakes when the number of players in the game is increased from two to three and the game is played for unusually high stakes with group composition being randomly changed from trial to trial the paradox is considerably weakened as players approach equilibrium play with multiple iterations of the stage game when the game is played with low stakes there is no evidence for equilibrium play or learning across iterations of the stage game an adaptive learning model that assumes updating of the individual probabilities of choice outperforms alternative static and dynamic models in accounting for the major results observed in the high stake experiment

strategy similarity and coordination in the payoff assessment model of choice sarin and vahid 1999 only the assessment of the chosen strategy is updated we extend that model to allow the agent to also update the assessments of strategies that the agent thinks are similar to the chosen strategy we use this model to explain observed behaviour in a recent experiment statistical tests cannot distinguish between the payoff distributions generated by the model and the observed payoff distributions in almost every period

aggregating infinite utility streams with intergenerational equity the impossibility of being paretian it has been known that in aggregating infinite utility streams there does not exist any social welfare function which satisfies the axioms of pareto intergenerational equity and continuity we show that the impossibility result persists even without imposing the continuity axiom and in frameworks allowing for more general domains of utilities than those used in the existing literature

pareto principles from inch to ell abstract under mild conditions including the possibility of compensation by monetary transfer this paper shows that all versions of the pareto principle viz the pareto indifference the weak pareto the strong pareto and the full pareto are in fact mutually equivalent

naive reinforcement learning with endogenous aspirations this article considers a simple model of reinforcement learning all behavior change derives from the reinforcing or deterring effect of instantaneous payoff experiences payoff experiences are reinforcing or deterring depending on whether the payoff exceeds an aspiration level or falls short of it over time the aspiration level is adjusted toward the actually experienced payoffs this article shows that aspiration level adjustments may improve the decision maker s long run performance by preventing him or her from feeling dissatisfied with even the best available strategies however such movements also lead to persistent deviations from expected payoff maximization by creating probability matching effects

the internal economics of the firm evidence from personnel data we analyze twenty years of personnel data from one firm the hierarchical structure is quite simple and stable career movements suggest that the employee s rate of learning and the firm s learning about ability are important there are promotion fast tracks exit rates vary little with tenure or salary the firm has personnel policies like those described in the internal labor markets literature although several theoretical preconditions for ilms such as ports of entry and exit are lacking job levels are important to compensation but there is also substantial individual variation in pay within levels our companion paper in this issue explores the wage policy of this firm

the productivity effects of privatization longitudinal estimates from hungary romania russia and ukraine this paper estimates the effect of privatization on multifactor productivity using comprehensive panel data on initially state owned manufacturing firms in four economies we exploit the data s longitudinal dimension to control for preprivatization selection and estimate long run impacts the estimates are robust to functional form but sensitive to selection controls our preferred random growth estimates imply positive multifactor productivity effects of 15 percent in romania 8 percent in hungary and 2 percent in ukraine but a 3 percent effect in russia the foreign privatization effect is larger 18 35 percent in all countries positive domestic effects appear immediately in hungary romania and ukraine and continue growing thereafter but emerge only five years after privatization in russia

a dynamic analysis of human welfare in a warming planet anthropogenic greenhouse gas ghg emissions have caused atmospheric concentrations with no precedents in the last half a million years inducing serious uncertainties about future climates and their effects on human welfare recent climate science supports the view that the climate stabilization will require very low ghg emissions in the future we ask is a path of low emissions compatible with sustainable levels of human welfare with steady growth in human quality of life addressing these questions requires both defining welfare criteria and empirically estimating the possible paths of the economy we specify and calibrate a dynamic model with four intertemporal links education physical capital knowledge and the environment in line with nordhaus 2008a and with the stern review 2007 we assume that ghg emissions allow increased production while a higher stock of atmospheric carbon decreases production our index of human welfare which we call quality of life quol emphasizes education knowledge and the environment affected by greenhouse gas emissions in addition to consumption and leisure thus we avoid a consumptionist fallacy that welfare depends only on commodity consumption and perhaps leisure we reject discounted utilitarianism as a normative criterion and consider two alternatives the first is an intergenerational maximin criterion which maximizes the quality of life of the first generation subject to maintaining at least that level for all successive generations the second is human development optimization that seeks the maximization of the quol of the first generation subject to achieving a given constant rate of growth in all subsequent generations hence our analysis focuses on a human notion of sustainability as opposed to the conventional green sustainability limited to keeping the quality of the environment constant because our dynamic optimization programs defy explicit analytical solutions our approach has been computational as a benchmark we consider a simple model with physical and human capital for which we prove a turnpike theorem we then devise a computational algorithm inspired by the turnpike property to construct feasible although not necessarily optimal paths in the more complex and realistic model our analysis indicates that with ghg emission paths entailing very low emissions in the future positive rates of growth in quol are possible while the first generation experiences a quol higher than the historical reference level we also observe a tradeoff between the quality of life of the first generation and the rate of growth in the quality of life yet generation 1 s sacrifice for the sake of a higher growth rate appears to be small the paths that we compute involve investments in knowledge at noticeably higher levels than in the past

privatization labor and social safety nets privatization promotes economic efficiency and growth thereby reinforcing macroeconomic adjustment in the short run however it can lead to job losses and wage cuts for workers this paper discusses these adverse impacts of privatization in terms of various methods of privatization and surveys the existing empirical evidence it finds that public sales and auctions can have stronger negative effects on workers but maximize the government s revenue policymakers options for mitigating the social impact of privatization are surveyed copyright 2001 by blackwell publishers ltd

globalization and the gender wage gap there are several theoretical reasons why globalization will have a narrowing as well as widening effect on the gender wage gap but little is known about the actual impact except for a number of country studies the author provides a cross country study of the impact of globalization on the occupational gender wage gap based on the rarely used but most far ranging survey of wages around the world the international labour organization s october inquiry this annual survey was started in 1924 and contains a wealth of information on wages and the gender wage gap for the period 1983 99 there is information on the gender wage gap in 161 narrowly defined occupations in more than 80 countries around the world the author finds the following i the occupational gender wage gap appears to be narrowing with increases in gdp per capita ii there is a significantly narrowing impact of trade and foreign direct investment fdi net inflows on the occupational gender wage gap for low skill occupations both in poorer and richer countries and for high skill occupations in richer countries iii there is no evidence of a narrowing impact of trade but there is evidence of a widening impact of fdi net inflows on the high skill occupational gender wage gap in poorer countries iv wage setting institutions have a strong impact on the occupational gender wage gap in richer countries

do public ownership and lack of competition matter for wages and employment evidence from personnel records of a privatized firm do public sector firm ownership and lack of competition matter for wages and employment to address this question we consider a large public sector company that is privatized using personnel records we find employment contract liberalization to generate relative wage losses for older high tenure low skilled part time workers permanent residents and women employment reductions mostly affect the same groups experiencing a wage decline overall wage liberalization leads to an increase in wage inequality of between 6 and 9 which if applied to the whole public sector would lead to a 52 to 76 closure of the inequality gap between the private and public sectors in europe our results suggest that differences between public and private sector wage structures found in descriptive studies are to a large extent causal rather than the result of selection into these sectors and that public sector employment and career path regulations limit a firm s ability to maintain a competitive workforce

mind the gender wage gap the impact of trade and competition on sectoral wage differences this paper examines differences between women s and men s wages in 18 selected oecd countries in the period 1970 to 2005 the study is based on 12 manufacturing sector and skill specific sets of panel data on the gender wage gap we apply a system generalised method of moments gmm estimator to the extended version of the conditional gender wage gap convergence equation controlling for sector concentration and industry specific measures of openness using a difference in difference approach trade affected concentrated sectors versus trade affected competitive sectors the results indicate that i an increase in sector concentration is associated with wage gap growth ii both import and export penetration are associated with a reduction of the high skill gender wage gap growth in concentrated industries iii there is evidence of a widening impact of trade on the medium and low skill occupational gender wage gap growth in less competitive industries iv institutional regulations of the labour market have an impact on the development of the gender wage gap for highly skilled labour an increase in labour market regulation raises the growth of the gender wage gap while for medium and low skilled workers it lowers it

any non welfarist method of policy assessment violates the pareto principle a comment in a recent article kaplow and shavell 2001 claim that any methodof policy assessment that is not purely welfarist violates the pareto prin ciple kaplow and shavell use the term welfarism to describe notionsof social welfare under which assessment of policies depends exclusivelyon their effects on individuals utilities p 281 a welfarist policy as sessment uses a social welfare function from the set

simple play in the prisoner s dilemma abstract players do not have knowledge of the objective game they know the available strategies and have scalar valued non probabilistic payoff assessments they act myopically always choosing the strategy they consider best they update these assessments in the direction of the received payoff it is shown that such players converge to choose their maxmin strategies when facing a game against nature in the prisoner s dilemma however the players need not converge to their maxmin strategy and often end up cooperating

liberal egalitarianism and the harm principle this paper analyses the implications of classical liberal and libertarian approaches for distributive justice in the context of social welfare orderings an axiom capturing a liberal non interfering view of society named the weak harm principle is studied whose roots can be traced back to john stuart mill s essay on liberty it is shown that liberal views of individual autonomy and freedom can provide consistent foundations for social welfare judgements in both the finite and the infinite context in particular a liberal non interfering approach can help to adjudicate some fundamental distributive issues relative to intergenerational justice however a surprisingly strong and general relation is established between liberal views of individual autonomy and non interference and egalitarian principles in the rawlsian tradition

assessing the impact of a wage subsidy for single parents on social assistance this paper studies the impact of a wage subsidy program aimed at long term social assistance recipients in quebec the program closely mimics the self sufficiency project and was implemented for a trial period of one year in 2002 we focus on the labour market transitions of the targeted population starting one year before the implementation of the program and up until the end of 2005 our results show that the duration of spells off social assistance increased while the duration of social assistance spells decreased slightly the response to the program varies considerably both with observed and unobserved characteristics

privatisation and x inefficiency a bargaining approach the usual analysis of privatization and x inefficiency uses agency theory to model managerial effort the authors model worker effort as determined by a bargain between firms and workers workers dislike effort because it lowers utility firms prefer high effort because it raises productivity public sector firms are assumed to be social welfare maximizers and therefore compared to private sector firms they bargain lower effort levels since they have the interests of consumers and workers at heart the authors model predicts that under certain conditions privatization should raise effort and so lower x inefficiency and that wages may increase or decrease copyright 1995 by blackwell publishing ltd

case based decision theory this paper suggests that decision making under uncertainty is at least partly case based we propose a model in which cases are primitive and provide a simple axiomatization of a decision rule that chooses a best act based on its past performance in similar cases each act is evaluated by the sum of the utility levels that resulted from using this act in past cases each weighted by the similarity of that past case to the problem at hand the formal model of case based decision theory naturally gives rise to the notions of satisficing decisions and aspiration levels

measuring beliefs and rewards a neuroeconomic approach the neurotransmitter dopamine is central to the emerging discipline of neuroeconomics it is hypothesized to encode the difference between expected and realized rewards and thereby to mediate belief formation and choice we develop the first formal test of this theory of dopaminergic function based on a recent axiomatization by caplin and dean 2008a these tests are satisfied by neural activity in the nucleus accumbens an area rich in dopamine receptors we find evidence for separate positive and negative reward prediction error signals suggesting that behavioral asymmetries in response to losses and gains may parallel asymmetries in nucleus accumbens activity

using propensity matching estimators to evaluate the impact of privatization on wages whether the transfer of ownership rights to the private sector leads to a decline or increase in wage growth is theoretically ambiguous given that the outcome depends on the uncertain interaction between firms and workers using propensity matching techniques this article investigates the effects of privatization on wages in the portuguese banking industry the empirical results obtained from quadros de pessoal for the period between 1989 and 1997 generally show a negative positive short run long run effect of privatization on relative wage growth for both men and women retained in the privatized firms moreover the results show that the most educated and experienced oldest workers as well as those in the high skill occupational categories were more likely to experience a negative wage effect

is there less discrimination in occupations where recruitment is difficult the authors empirically test the cross sectional relationship between hiring discrimination and labor market tightness at the level of the occupation to this end they conduct a correspondence tes

enjoying the quiet life corporate governance and managerial preferences much of our understanding of corporations builds on the idea that managers when they are not closely monitored will pursue goals that are not in shareholders interests but what goals would managers pursue this paper uses variation in corporate governance generated by state adoption of antitakeover laws to empirically map out managerial preferences we use plant level data and exploit a unique feature of corporate law that allows us to deal with possible biases associated with the timing of the laws we find that when managers are insulated from takeovers worker wages especially those of white collar workers rise the destruction of old plants falls but the creation of new plants also falls finally overall productivity and profitability decline in response to these laws our results suggest that active empire building may not be the norm and that managers may instead prefer to enjoy the quiet life

modelling cognitively bounded rationality an evaluative taxonomy abstract since its origins in the 1950s the notion of bounded rationality has been incorporated into economic theory using an array of methodological approaches this paper presents a taxonomy by which these approaches can be categorized and understood evaluating each approach against a range of important criteria at a time when the foundations of economic theory are being re examined this paper should be viewed as a first step towards an assessment of the appropriate role that this more realistic view of cognition should take in different areas of economic theory and also of the desirable characteristics of models that incorporate it

substitution and dropout bias in social experiments a study of an influential social experiment this paper considers the interpretation of evidence from social experiments when persons randomized out of a program being evaluated have good substitutes for it and when persons randomized into a program drop out to pursue better alternatives using data from an experimental evaluation of a classroom training program we document the empirical importance of control group substitution and treatment group dropping out evidence that one program is ineffective relative to close substitutes is not evidence that the type of service provided by all of the programs is ineffective although that is the way experimental evidence is often interpreted

explaining wage inequality in telecommunications services customer segmentation human resource practices and union decline this study examines factors related to within occupation wage inequality among service and sales workers in the telecommunications industry the author draws on a 1998 survey of a nationally representative sample of 354 service and sales centers in the industry to examine the importance of management practices and union institutions in shaping wage variation the results strongly indicate that business strategies of customer segmentation and human resource practices explain variation in wages over and above that explained by the human capital of the work force in addition despite extensive deregulation and de unionization of the industry the union wage premium is 22

on the impossibility of complete non interference in paretian social judgements abstract we study a principle of non interference in social welfare judgements non interference captures aspects of liberal approaches particularly a millian approach to social decision making in its full generality non interference produces an impossibility result together with weak pareto optimality it implies that a social welfare ordering must be dictatorial however interesting restricted versions of non interference are compatible with standard social welfare orderings

contesting the magic of the market place black employment and business concentration in the urban context the spatial decentralisation of urban firms has been the primary focus of urbanists seeking to understand how black employment is impacted by the changing nature of business in the us very little attention has been given to the impact of market concentration on black employment in the urban environment using the most recent data available from the equal employment opportunity commission the paper finds that black male and female employment is positively associated with greater market concentration not greater market competition as predicted by some neo classical economists there is little support for the contention that economic forces at work in competitive markets tend to minimise discrimination either in the urban environment or in the nation as a whole the central city continues to be an important factor in black employment because central city firms are in industries with higher market concentration which tend to employ more black workers however increased market concentration is a crucial
