wage determination in brazil the growth of union bargaining power and informal employment this article examines wage determination in brazilian manufacturing during the 1980s and early 1990s it presents evidence to show that the reduction in state regulation of collective bargaining has led to the development of a system of wage determination which is increasingly characterised by rent sharing and insider trade union bargaining power real wages appear increasingly inflexible with respect to movements in open unemployment with a large informal sector disciplining formal sector wage bargaining and cushioning the impact of broader labour market conditions an important consequence of this is that the employment costs of a successful counter inflationary strategy may be very severe

collective bargaining arrangements closed shops and relative pay this paper uses establishment level data to examine the impact on union nonunion pay differentials of the industrial relations setting in which bargaining takes place the pre entry closed shop is found to be of prime importance for the pay of both skilled and semiskilled manual workers for skilled workers and for semiskilled workers in larger establishments the differentials are found to be insignificantly different from zero in the absence of a pre entry closed shop copyright 1987 by royal economic society

pay setting self employment and the unions one of the important influences that has shaped recent labour market policy is the idea that pay should depend on the employer s financial per formance this is believed both by politicians and by businessmen and comes in various guises it was the subject of long debate in the spring issues of the financial times prime minister john major argued that there should be no such thing as automatic pay increases pay must be linked to

relative earnings and individual union membership in the united kingdom considerable attention has been focused in recent years on the empirical analysis of the effect of trade unions on the structure of earnings such empirical investigation usually entails measurement of the union non union differential in wages or earnings at the level of the individual this involves comparison of the earnings of union members with estimates of what their earnings would be were they not union members or equivalently examination of differences in earnings between individuals comparable with regard to all other relevant characteristics who differ in their union membership alone in the united kingdom all previous attempts at estimation of this differential have used aggregate data at either the industry or occupation level 1 the conventional methodology involves regression of the logarithm of the average wage on either the proportion of workers who are union members or the proportion covered by a collective agreement together with a vector of industry characteristics that are deemed to determine the non union wage however several problems are immediately apparent with this methodology first the model ignores the possibility of variation in the differential across industries which has potentially serious consequences second the vector of other characteristics customarily used is somewhat limited and raises doubts concerning the adequacy of the standardization for what might loosely be termed labour quality third only a sub sample of industries is ever used owing to lack of data those industries excluded are generally smaller in terms of employment that those included if the differential varies with the size of the industry a further bias will be induced all of these problems are either removed or lessened by the use of individual level data for an analysis of their impact at the industry level see geroski and stewart 1981 2 as a result it is now widely accepted that the appropriate way to measure such differentials is to use micro data sets at the level of the individual worker until recently suitable data have not been available for the united kingdom and hence such analysis was not possible this paper presents the first estimates for the united kingdom based on individual level data if the value of the union non union differential were the same for all workers in the unionized sector analysis at the industry level and the individual level would produce similar results however the marshallian laws of derived demand suggest that this will not be the case despite this clear prediction of variation in the differential there has been little systematic investigation of the variation this paper also presents such an analysis since variation in the differential across industries results in aggregation bias in industry level studies such an analysis is of considerable relevance to the evaluation of the evidence from such studies as well as being of interest in its own right the paper is laid out as follows section i presents a method of estimating the union non union differential at the individual level while section ii

one man one bid abstract we compare two mechanisms to implement a simple binary choice e g adopt one of two proposals we show that when neither alternative is ex ante preferred simple majority voting cannot implement the first best outcome we introduce a simple bidding mechanism where votes can be bought at a quadratic cost and voters receive rebates equal to the average of others payments this mechanism is budget balanced individually rational and fully efficient in the limit moreover the mechanism redistributes from those that gain from the outcome to those that lose and everyone is better off under bidding compared to voting we test the two mechanisms in the lab using an environment with moderate and extremist voters the observed efficiency losses under voting are close to theoretical predictions and significantly larger than under bidding because of redistribution the efficiency gain from bidding benefits mostly the moderate voters

the low skill trap recently it has become popular to argue that certain workers have fallen into a trap in which they have poor skills few job opportunities and a low return on training while others have not this paper demonstrates how such a trap can occur within a simple matching model with rent sharing rent sharing diminishes the worker s incentive to acquire skills however since firms also benefit from training rent sharing likewise induces job creation the subsequent improved matching prospects may offset the initial disincentive to invest however for this mechanism to be effective firms and workers must coordinate their actions if they do not the trap occurs

regional disparities in the unemployment rate the role of the wage setting mechanism in spain 1987 92 bande r fernandez m and montuenga v m 2007 regional disparities in the unemployment rate the role of the wage setting mechanism in spain 1987 92 regional studies 41 the aim of this paper is to show how regional unemployment disparities in spain widen during economic upturns and to provide an explanation of this behaviour the analysis is based on the study of the wage setting mechanism that allows an estimation of the responses of wages to both labour productivity and the general situation of the labour market and an assessment of their impact on the evolution of regional unemployment the results of this estimation at the regional level with manufacturing data confirm the existence of marked differences between industries and between regions these responses these differences can be interpreted as a distinctive wage setting mechanism across industries and regions which may explain the evolution of unemployment rates within the regional labour markets bande r fernandez m et montuenga v

gender differences in rent sharing and its implications for the gender wage gap evidence from sweden abstract this study using matched employer employee data analyses gender differences in rent sharing results indicate significantly smaller remuneration from firm profits for women a difference that increases along the wage distribution gender differences in rent sharing explain less than 2 of mean gender wage differentials as differences are found in remuneration from firm profit and not in the mean profit levels of employing firms

fear unemployment and pay flexibility the paper uses newly available cross section data to study wage determination in the united kingdom in the 1980s the main results are as follows 1 fear of unemployment substantially depresses pay 2 there is some evidence of a wage ratchet whereby rates of pay are more flexible upwards than downwards 3 the unemployment elasticity of pay averages 0 1 and 4 wages are much more flexible in nonunion workplaces than they are in union workplaces copyright 1991 by royal economic society

the role of bounded rationality and imperfect information in subgame perfect implementation an empirical investigation in this paper we conduct a laboratory experiment to test the extent to which moore and repullo s subgame perfect implementation mechanism induces truth telling in practice both in a setting with perfect information and in a setting where buyers and sellers face a small amount of uncertainty regarding the good s value we nd that moore repullo mechanisms fail to implement truth telling in a substantial number of cases even under perfect information about the valuation of the good this failure to implement truthtelling is due to beliefs about the irrationality of one s trading partner therefore although the mechanism should in theory provide incentives for truth telling many buyers in fact believe that they can increase their expected monetary payo by lying the deviations from truth telling become signicantly more frequent and more persistent when agents face small amounts of uncertainty regarding the good s value our results thus suggest that both beliefs about irrational play and small amounts of uncertainty about valuations may constitute important reasons for the absence of moore repullo mechanisms in practice

the innovative behavior of spanish enterprises and its impact on salaries our aim was to analyze the effects of firms innovative behavior on their employees salaries in the spanish manufacturing industry we found a premium in the wage paid by innovative firms regardless of size however when taking company size into account we found that the effect of innovations was greater in small medium enterprises sme contrary to what was expected the inferences of the models estimated suggest that the higher the market concentration the weaker the appropriability regime especially for smes however at the same time a firm s innovations reduce the impact of market concentration on wages making innovating firms more autonomous than non innovating ones even more to be able to innovate firms have to isolate their employees salaries from the product market these results hold regardless of firm s size but have a greater impact on the small medium group of firms finally our analysis backs the assumption that salaries in both large and small medium firms are generated by two distinct economic regimes supporting the proposition that an sme is not simply a scaled down large firm

wages profits and capital intensity evidence from matched worker firm data swedish data on workers matched with firms balance sheet reports are used to examine the relation between wages and firms ability to pay results indicate that experienced and highly educated workers are sorted into profitable firms wages are positively correlated with profits and the capital labor ratio after controlling for worker quality degree of effort supervision job characteristics local unemployment firms employment history and employer size lester s range of pay due to rent sharing is around 12 24 of the mean wage in sweden which is close to the estimates for the united states and united kingdom

a new theory of corporatism and wage setting abstract the standard view on corporatist institutions for wage setting in many european economies is based of the insider outsider model corporatism is associated with lack of wage flexibility this paper discusses a new approach starting from the importance of nominal contracts the rationale for these contracts is to avoid future bargaining adjusting these contracts ex post to aggregate shocks would raise their efficiency however avoiding the bargaining required for this adjustment was the main reason for negotiating these contracts in the first place this is the fundamental contradiction under corporatism outside institutions can play this role these institutions provide therefore a type of flexibility not available in decentralized economies empirical evidence supports the basic ideas of this model

l investissement francais dans les colonies 1876 1940 une autre analyse de l enquete de gouvernement de vichy 1943 this paper presents an econometric model of trade union membership in the united kingdom the empirical model utilizes cyclical variables in the explanation of membership changes and separates the short and long run dynamics explicitly it proves to be a superior specification to previous business cycle models estimated for the united kingdom and predicts satisfatorily the recent decline in membership the inclusion of a dummy variable reflecting the political complexion of the government is the only secular variable which significantly improves equation performance but the composition of changes in employment plays no part in explaining the recent decline in membership copyright 1988 by the london school of economics and political science

efficient collective decision making marginal cost pricing and quadratic voting we discuss the mechanisms related to quadratic voting from vickrey s counter speculation mechanism and his second price auction through the family of groves mechanisms and its most notable member the clarke mechanism to the expected externality mechanism goeree and zhang s mechanism the groves ledyard mechanism and the hylland zeckhauser mechanism we show that each mechanism that involves collective decisions has a quadratic aspect and that all of the mechanisms that we discuss are applications of the fundamental insight that for a process to be efficient all parties involved must bear the marginal social costs of their actions

learning dynamics for mechanism design an experimental comparison of public goods mechanisms in a repeated interaction public goods economy incomplete information and dynamic behavior may affect the realized outcomes of mechanisms known to be efficient in a complete information oneshot game an experimental test of five public goods mechanisms indicates that subjects with private information appear to best respond to recent observations this provides predictions about which mechanisms will generate convergence to their efficient equilibrium allocations these predictions match the experimental result that globally stable efficient mechanisms realize the highest efficiency in practice the simplicity of the suggested best response model makes it useful in predicting stability of mechanisms not yet tested

imperfectly competitive labour markets and the productivity puzzle abstract we integrate imperfectly competitive labour markets in a dynamic macromodel in accordance with empirical evidence we find that temporary shocks are consistent with little real wage and large employment responsiveness while permanent shocks affect real wages and not employment

environmental taxation and unemployment some evidence on the double dividend hypothesis in europe abstract the employment double dividend hypothesis suggests that an appropriately designed fiscal reform in which emission charges are used to subsidize employers social security contributions may realize at least two relevant policy goals a better quality of the environment and at the same time an increase in employment levels this paper uses a newly developed econometric general equilibrium model for the european union as well as for each member country and presents simulation results up to the year 2010 of the effects of a european carbon tax the revenues from which are recycled to reduce employers social security contributions the results show that recycling carbon tax revenues may provide an employment double dividend only in the short run

firm profitability regional unemployment and human capital in wage determination this paper presents an analysis of wage formation in the norwegian private sector using data for individual workers matched with firm level information and regional unemployment a key issue is to test whether or not firm specific variables affect individual wages after controlling for individual specific factors and working conditions the results imply positive effects of firm specific profitability and firm size the elasticity of wages with respect to value added per worker and firm size is 5 and 3 3 respectively empirical evidence of a downward sloping regional wage curve is also reported while there is no support of the hypothesis of compensating wage differentials since data for three levels of aggregation are used the ols estimates of the standard errors are downward biased therefore results using a random effects model are also reported taking the multi level structure of the data into account

team selection with asymmetric agents abstract in shallow markets where there are mutual gains from cooperation among agents collusive behavior may occur even if it does not constitute a nash equilibrium yet such behavior is rarely sustainable bolle 1994 reports the results of one period team selection experiments in which subjects often did not follow the nash equilibrium behavior but engaged in tacit collusion we test the robustness of bolle s findings by introducing asymmetry into subjects characteristics and repeating the experiment for a number of periods we find that collusion is not sustainable and the outcomes converge to levels close to the nash equilibrium however the agent s actions stayed slightly above the nash equilibrium level in all experiments

out of equilibrium performance of three lindahl mechanisms experimental evidence abstract we describe an experimental comparison of the out of equilibrium performance of three allocation mechanisms designed to achieve lindahl outcomes as nash equilibria the mechanisms due to walker 1981 kim 1993 and chen 2002 we find that chen s mechanism which is supermodular converges closest and most rapidly to its equilibrium however we find that the properties that move subjects toward equilibrium in chen s mechanism typically generate sizeable taxes and subsidies when not in equilibrium and correspondingly large budget surpluses and deficits which typically far outweigh the surplus created by providing the public good the kim mechanism on the other hand converges relatively close to its equilibrium and exhibits much better out of equilibrium efficiency properties

work sharing employment and wages the paper analyzes the effects of a reduction in working time on wages and employment with a monopoly union in general it is not clear in which directions these variables move but if employment and working time are perfect substitutes the effects are related to how working time has been determined initially the wage increases if initial working time is smaller than or equal to the trade union optimum whereas the result is unclear when it is larger in this case it is never optimal for a trade union to reduce both the wage and working time in response to a recessionary supply shock the analysis may help to explain varying attitudes towards work sharing in different countries

insider forces in wage determination new evidence for norwegian industries using panel data for norwegian industries we establish a significant permanent relation between industry wages and industry profitability the estimated long run insider weight is above 0 2 and stable both over time and across industries industry wages are significantly affected by aggregate unemployment and the preferred wage equation implies a highly convex wage curve

union wage differentials product market influences and the division of rents this paper examines the extent to which product market conditions limit the ability of trade unions to establish wage differentials over nonunion pay the mean union pay differential is estimated to be of the order of 8 percent to 10 percent in establishments with some degree of product market power but zero in establishments facing competitive product market conditions when competitive conditions are faced a preentry closed shop and high union coverage of the industry are both required it is estimated that only 5 percent of the establishments in which there are significant differentials over nonunion pay face generally competitive product market conditions copyright 1990 by royal economic society

non excludable public good experiments we conduct a two stage game experiment with a non excludable public good in the first stage two subjects choose simultaneously whether or not they commit to contributing nothing to provide a pure public good in the second stage knowing the other subject s commitment decision subjects who did not commit in the first stage choose contributions to the public good we found no support for the evolutionary stable strategy equilibrium and the ratio of subjects who did not commit to contributing nothing increased as periods advanced that is the free riding rate declined over time furthermore this behavior did not arise due to altruism or kindness among subjects but from spiteful behavior of subjects

relative performance of two simple incentive mechanisms in a public goods experiment we compare the performance of two incentive mechanisms in public goods experiments one mechanism the falkinger mechanism rewards and penalizes agents for deviations from the average contributions to the public good falkinger mechanism the other the compensation mechanism allows agents to subsidize the other agents contributions compensation mechanism it is found that both mechanisms lead to an increase in the level of contributions to the public goods however the falkinger mechanism predicts the average level of contributions more reliably than the compensation mechanism

convergence an experimental study of teaching and learning in repeated games nash equilibrium can be interpreted as a steady state where players hold correct beliefs about the other players behavior and act rationally we experimentally examine the process that leads to this steady state our results indicate that some players emerge as teachers those subjects who by their actions try to influence the beliefs of their opponent and lead the way to a more favorable outcome and that the presence of teachers appears to facilitate convergence to nash equilibrium in addition to our experiments we examine games with different properties from other experiments and show that teaching plays an important role in these games we also report results from treatments in which teaching is made more difficult in these treatments convergence rates go down and any convergence that does occur is delayed jel c70 c91 d83 d84

labour market institutions and economic performance labour markets richard freeman do particular types of labour market institution hold the key to economic success should other countries try to emulate the flexibility of the american labour market or the centralization of swedish style corporatism since 1970 within the oecd there has been a sharp divergence both of economic performance and of indicators of labour market structure the paper uses union density and the degree of wage dispersion across industries to proxy a country s underlying labour market institutions in assessing economic performance it is argued that cross country differences in output growth were much smaller than differences in employment growth for given output growth there is a clear negative relationship between employment growth and real wage growth across countries why do different countries find themselves at different points on this trade off the final part of the paper examines the correlation between indicators of labour market structure and the position on the wage employment trade off it concludes that the degree of wage dispersion across industries is the most important indicator of market structure and that countries with very high or very low dispersion typically the countries with highly centralized or highly decentralized bargaining in the labour market have better employment performance than countries with intermediate degrees of centralization and wage dispersion

union wage differentials in the face of changes in the economic and legal environment this paper examines changes in union wage differentials in britain between 1980 and 1984 on the basis of two comparable establishment level data sets this period saw considerable economic and legislative change with potential effects on the outcomes of collective bargaining despite these changes the mean differential has little change between these two years and what there is is attributable to compositional changes such as the shift away from the manufacturing sector and the downward shift in the establishment size distribution the impact of the changes in unemployment and union coverage that took place is found to be minimal copyright 1991 by the london school of economics and political science

rent sharing and collective wage contracts evidence from german establishment level data using german establishment level data this article analyses whether wages respond to firm specific profitability conditions particular emphasis is given to the question of whether the extent of rent sharing varies with collective bargaining coverage in this context two conflicting hypotheses are tested the first one asserts that unions exploit their bargaining power at the firm level and appropriate a larger share of rents than the bargaining parties in uncovered firms the second one states that unions favour a compressed intra industry wage structure and suppress the responsiveness of wages to firm specific profitability conditions the empirical analysis provides strong support for the second hypothesis while pooled ordinary least squares pols estimates yield positive estimates of the rent sharing coefficient in covered establishments dynamic panel data estimates accounting for unobserved heterogeneity and the endogeneity of rents point to a rent sharing coefficient of zero

when does learning in games generate convergence to nash equilibria the role of supermodularity in an experimental setting this study clarifies the conditions under which learning in games produces convergence to nash equilibria in practice previous work has identified theoretical conditions under which various stylized learning processes achieve convergence one technical condition is supermodularity which is closely related to the more familiar concept of strategic complementarities we experimentally investigate the role of supermodularity in achieving convergence through learning using a game from the literature on solutions to externalities we systematically vary a free parameter below close to at and beyond the threshold of supermodularity to assess its effects on convergence we find that supermodular and near supermodular games converge significantly better than those far below the threshold from a little below the threshold to the threshold the improvement is statistically insignificant within the class of supermodular games increasing the parameter far beyond the threshold does not significantly improve convergence simulation shows that while most experimental results persist in the long run some become more pronounced

a nonuniform pricing model of union wages and employment unlike implicit contracts models the nonuniform pricing model of unions assumes that firms can always shut down ex post to avoid any payments to the union under this restriction employment can differ from a first best even if both workers and firms are risk neutral in general the union chooses to offer quantity discounts on labor and needs to use a seniority rule that regulates the order in which workers are hired to implement these discounts unions lower almost all workers employment probabilities and increase the cyclical volatility of employment and the union nonunion average wage differential will move countercyclically workers preferences over union wage profiles conditional on their seniority exhibit within limits a convenient unanimity property

the employer size wage gap evidence for britain university of edinburgh and university of sussexfinal version received 5 may 1992 this paper presents estimates for the employer plant size wage gap for britain using anordered probit model selectivity corrected wage equations are estimated for three plant sizecategories in a comparison between plants with more than 500 workers and those with lessthan 100 a wage gap estimate of over 17 per cent is detected the wage effects of unionizationin plants with more than 500 workers is reported as insignificant in contrast to evidenceprovided by idson and feaster 1990 for the united states no evidence of non randomsorting of workers across plant size is detected

wages profits and rent sharing the paper suggests a new test for rent sharing in the u s labor market using an unbalanced panel from the manufacturing sector it shows that a rise in a sector s profitability leads after some years to an increase in the long run level of wages in that sector the paper controls for workers characteristics for industry fixed effects and for unionism lester s range of wages is estimated for rent sharing reasons alone at approximately 24 per cent of the mean wage

the groves ledyard mechanism an experimental study of institutional design the groves ledyard mechanism theoretically can solve the free rider problem in public good provision in certain environments two questions are of overriding importance in implementing the mechanism the first is related to the actual performance of the mechanism in general the second is the choice of a punishment parameter which is the only parameter that is available for those who may want to actually use the mechanism thus the determination of the role of this variable on mechanism performance is fundamental for any advances along the lines of actual implementation in studying the groves ledyard mechanism we show that the punishment parameter plays a crucial role in the performance of the mechanism by using 1 and 100 we show that under the higher punishment parameter the groves ledyard equilibrium is chosen much more frequently a higher level of the public good is provided and efficiency is higher by examining two behavioral models we show that a higher leads to an increase in the probability of an individual choosing a best response predicted by the model the parameter alone explains nearly 70 of the data in both the cournot and the carlson auster behavioral model we also found that convergence to cournot behavior is faster and more stable under a high than under a low

real wage determination and rent sharing in collective bargaining agreements the microeconomic forces that influence real wages are not fully understood this paper studies pay determination using data on approximately 600 labour contracts it finds that the real wage is an increasing function of past profitability in the employer s industry and a decreasing function of the level of unemployment in the employer s region these results are consistent with rent sharing theories

microdata evidence on rent sharing we examine the effect of firm profits on wages for individual workers while focusing on the empirical complications associated with estimating the extent of rent sharing controlling for worker and firm fixed effects and using several instruments to deal with the endogeneity of profits we report results indicating that ordinary least square ols estimates strongly underestimate the effects of profits on wages moreover the effect of profits on wages are estimated separately for firms with increasing and decreasing profits within a given time period we find a positive and stable effect only in firms with increasing profits this is in line with the idea that falling profits do not lead to wage cuts while increasing profits imply higher wages

the trade union wage gap in britain some new estimates abstract new estimates of the union non union wage gap in britain derived from household data are reported the results about 12 for manual and about 4 for non manual workers expand upon the tentative conclusions of the few earlier similar british studies

rent sharing and collective bargaining coverage evidence from linked employer employee data using a linked employer employee data set this paper analyses the relationship between firm profitability and wages particular emphasis is given to the question of whether the sensitivity of wages to firm specific rents varies with collective bargaining coverage to address this issue we distinguish sector specific wage agreements firm specific wage agreements and wage determination without any bargaining coverage our findings indicate that individual wages are positively related to firm specific rents in the non union sector and under firm specific contracts industry wide wage contracts however seem to suppress firm level rent sharing while pooled ols estimates yield a positive correlation between wages and quasi rents under centralised contracts estimates accounting for unobserved individual and establishment heterogeneity point to a coefficient of zero differenced gmm estimates accounting for the endogeneity of our profitability measure even point to a negative relationship under centralised contracts

dynamic models of religious conformity and conversion theory and calibrations abstract this paper develops overlapping generations models to explain and simulate changes in the proportion of secular and religious people the church is modeled as generating an externality associated with conformity enhancing education observed changes in the number of nonbelievers are explained by different birth rates among secular and religious parents and the relative proportion of young nonconformists calibrations for the conformity rates among secular and religious people show that the observed long run increase in the difference between percentage of secular people in europe and the united states can be attributed to lower conformity rates prevailing in europe

shareholder wealth and wages evidence for white collar workers we present empirical evidence on the relationship between individual wages conditional on worker characteristics and equity returns using a unique survey from the bureau of labor statistics equity returns affect the wages only of workers with three or more years of tenure a 4 percent increase in a firm s market value raises pay by 0 3 percent within three years our estimates suggest that each 10 increase in shareholder wealth raises the present value of a firm s wage bill by 1 the elasticity of white collar wages with respect to equity returns is one third smaller than the ceo salary elasticities in our sample

profit related pay prose discovered this paper estimates that in 1984 43 percent of british private sector establishments had some form of profit related pay regression results do not show that these establishments had statistically significant better financial performance cross ta bulations do not suggest that the establishments with income sharing schemes had noticeably greater employment growth or better industrial relations copyright 1988 by royal economic society

unions and interindustry wage differentials abstract we investigate the importance of trade unions in collective bargaining in the context of a developing country manufacturing labor market the methodology we adopt to estimate wage differentials follows the method proposed by haisken denew j p and schmidt c m 1997 review of economics and statistics 79 516 521 since it improves on the standard procedure popularized by krueger a b and summers l h 1988 econometrica 56 193 259 our findings indicate that wage dispersion is far greater in the unionized sector of brazilian manufacturing in contrast to evidence from other countries

generalized groves ledyard mechanisms abstract groves and ledyard 1977 construct a mechanism for public goods procurement that can be viewed as a direct revelation groves mechanism in which agents announce a parameter of a quadratic approximation of their true preferences the mechanism s nash equilibrium outcomes are efficient the budget is balanced because groves mechanisms are balanced for the announced quadratic preferences tian 1996 subsequently discovered a richer set of budget balancing preferences we replicate the groves ledyard construction using this expanded set of preferences and uncover a new set of complex mechanisms that generalize the original groves ledyard mechanism the original mechanism however remains the most appealing in terms of both simplicity and stability

the determination of wages employment and work hours in an economy with centralised wage setting sweden 1950 83 a key component of recent explanations for the growth in unemployme nt in western europe is a negative relation between wage rates and employment this paper examines the evidence for such a relationship for swedish manufacturing industry and also investigates the corresponding movements of hours of work the findings form the ingredients of a structural model of the labor market which is estimated using time series observations from 1951 t o 1983 the greater volatility of employment relative to earnings is measured by a specific parameter which in this model relates to the objectives of trade unions copyright 1988 by royal economic society

social contagion and income heterogeneity in new product diffusion a meta analytic test standard diffusion models capture social contagion only coarsely and do not allow one to operationalize different contagion mechanisms moreover there is increasing skepticism about the importance of contagion and as has long been known s shaped diffusion curves can also result from heterogeneity in the propensity to adopt we present hypotheses about conditions under which specific contagion mechanisms and income heterogeneity are more pronounced and test these hypotheses using a meta analysis of the q p ratio in applications of the bass diffusion model the ratio is positively associated with the gini index of income inequality in a country supporting the heterogeneity in thresholds interpretation the ratio also varies as predicted by the gamma shifted gompertz diffusion model but the evidence vanishes after controlling for national culture as to contagion the q p ratio varies with the four hofstede dimensions of national culture for three of them in a direction consistent with the social contagion interpretation furthermore products with competing standards have a higher q p ratio which is again consistent with the social contagion interpretation finally we find effects of national culture only for products without competing standards suggesting that technological effects and culturally moderated social contagion effects might not operate independently from each other

an experimental analysis of unanimity in public goods provision mechanisms the paper reports on an experimental investigation of four methods of allocating public goods the two basic processes studied are direct contribution and a public goods auction process both of these processes are studied with and without an additional unanimity feature the results suggest that the auction process outperforms direct contribution the effect of unanimity is to decrease the efficiency of both processes much of the paper is focused on an analysis of these results

insider forces and wage determination this paper investigates the relative importance of firm specific factors i e insider forces in wage determination using firm level data on 219 u k companies over 1974 82 it finds that a 1 percent rise in a firm s prices or productivity relative to the aggregate economy leads to a rise in relative wages of 0 1 0 2 percent as a corollary to this outside factors like the aggregate wage and the unemployment rate also play an important role there is evidence for insider based hysteresis effects but these are inversely related to the extent to which firms take national agreements into account copyright 1990 by royal economic society

how network externalities can exacerbate intergroup inequality the authors describe a common but largely unrecognized mechanism that produces and exacerbates intergroup inequality the diffusion of valuable practices with positive network externalities through social networks whose members differentially possess characteristics associated with adoption the authors examine two cases the first to explore the mechanism s implications and the second to demonstrate its utility in analyzing empirical data in the first the diffusion of internet use network effects increase adoption s benefits to associates of prior adopters an agent based model demonstrates positive monotonic relationships given externalities between homophily bias and intergroup inequality in equilibrium adoption rates in the second rural urban migration in thailand network effects reduce risk to persons whose networks include prior migrants analysis of longitudinal individual level migration data indicates that network homophily interacts with network externalities to induce divergence of

specification induced uncertainty in the estimation of trade union wage differentials from industry level data at a more specific level the paper is concerned with the estimation of union non union wage differentials from industry level data for the uk manufacturing sector metcalf 1977 reviewing the evidence from such industry level studies concludes that they suggest that a figure of 20 per cent may not be dreadfully in error for the average earnings differential received by manual workers who are covered by a collective agreement a more recent study at the individual level for union membership stewart 1983 suggests that a figure of below 10 per cent may be more appropriate however metcalf s summary figure remains representative of the industrylevel evidence this paper concentrates on two particular problems inherent in these industry level studies and in studies in other areas using such cross section data the first of these concerns the potential industry specificity of parameter values in the case of union wage differentials the marshallian laws of derived demand provide theoretical grounds for expecting the differential to vary across industries failure to take proper account of this will in general result in biased estimation even of the average differential in addition interpreting the estimated average differential as if it were that to be found in a typical industry may be a highly misleading representation of the impact of collective bargaining on the wage structure section i of this paper is concerned with this inter industry variation in the differetial and in particular with modelling how the differential varies with the extent of coverage in the industry our finding is that there is a large inter industry variation in the differential with the average being made up of a large differential in a small group of industries and a much smaller and insignificant differential in the majority of industries in such circumstances the estimated average differential is not representative of that prevailing in either group

inequality among american families with children 1975 to 2005 from 1975 to 2005 the variance in incomes of american families with children increased by two thirds in attempting to explain this trend labor market studies emphasize the rising pay of college graduates while demographers typically highlight the implications of family structural changes across time in this article we join these lines of research by conceiving of income inequality as the joint product of the distribution of earnings in the labor market and the pooling of incomes in families we develop this framework with a decomposition of family income inequality using annual data from the march current population survey our analysis shows that disparities in education and single parenthood contributed to income inequality but rising educational attainment and women s employment offset these effects most of the increase in family income inequality was due to increasing within group inequality which was widely shared across family types and levels of schooling

the rise in unemployment a multi country study one of the most remarkable features of recent economic history has been the remorseless rise in unemployment throughout the industrialized countries however while the trend to higher unemployment is universal the experience of individual countries also differs widely the increase is especially marked within the european community where unemployment rates rival those reached in the interwar years by contrast in the scandinavian countries and japan unemployment is lower and has risen very much less experience in the united states lies somewhere between these extremes and in the last few years unemployment there has fallen sharply

make money surfing the web the impact of internet use on the earnings of u s workers much research on the digital divide presumes that adults who do not use the internet are economically disadvantaged yet little research has tested this premise after discussing several mechanisms that might produce differences in earnings growth between workers who do and do not use the internet we use data from the current population survey to examine the impact of internet use on changes in earnings over 13 month intervals at the end of the internet boom our analyses reveal robustly significant positive associations between web use and earnings growth indicating that some skills and behaviors associated with internet use were rewarded by the labor market consistent with human capital theory current use at work had the strongest effect on earnings in contrast to economic theory which has led economists to focus exclusively on effects of contemporaneous workplace technology use workers who used the internet only at home also did better suggesting that users may have benefited from superior

the thatcher miracle since 1979 productivity growth in britain has improved markedly compared with europe the turnaround in productivity growth has two main causes the british economy was subjected to a far more severe contraction of demand in 1980 81 than any other country this led to a new realism which was sustained by the legal changes in trade union power since 1979 there has been a worsening in the trade off between unemployment and inflation the poor unemployment inflation trade off is due to the neglect of skill training and education causing skill shortages and to the build up of long term unemployment which does little to restrain inflation this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed f this abstract was borrowed from another version of this item

what s driving mexico u s migration a theoretical empirical and policy analysis using data gathered in 25 mexican communities the authors link individual acts of migration to 41 theoretically defined individual household community and macroeconomic level predictors the indicators vary through time to yield a discrete time event history analysis over the past 25 years probabilities of first repeat and return migration have been linked more to the forces identified by social capital theory and the new economics of migration than to the cost benefit calculations assumed by the neoclassical model the authors find that mexico u s migration stems from three mutually reinforcing processes social capital formation human capital formation and market consolidation

experiments with the pivot process for providing public goods interest in demand revealing mechanisms for providing public goods has both waned and then renewed over the past two decades the possibility of using such mechanisms in different venues than originally anticipated sparked the research reported here the specific motivation for this paper is to conduct a series of simple direct tests of one version of the class of mechanisms failure of demand revelation was much more expensive than we had expected even when compared to previous research with related mechanisms the reason for this remains an open question

public goods and voting on formal sanction schemes abstract the burgeoning literature on the use of sanctions to support the provision of public goods has largely neglected the use of formal or centralized sanctions we let subjects playing a linear public goods game vote on the parameters of a formal sanction scheme capable of either resolving or exacerbating the free rider problem depending on parameter settings most groups quickly learned to choose parameters inducing efficient outcomes we find that cooperative orientation political attitude gender and intelligence have a small but sometimes significant influence on voting

local and central wage bargaining the literature on wage bargaining usually considers either central or local wage bargaining an exception is holmlund 1986 throughout most of the unionized part of the private sector in norway wage bargaining takes place on two levels first centrally and then locally in the economic policy debate it has been argued that this system leads to higher wages and lower employment than bargaining on only one level regardless of whether it is central or local see e g skatnland 1983 in this paper i present a model with wage bargaining on two levels and show that in this system the above argument is proved false we focus on an industry with n identical firms which produce one homogeneous product for simplicity the output price and input prices other than wages are considered given on the central level there is a utility maximizing labor union with a quasi concave utility function increasing in the arguments employment l and total wage vv there is a local labor union in each firm we analyze the system during one period say a year wage setting in this period consists of three stages in the first stage the central labor union sets the tariff wage q unilaterally this follows the monopoly model of e g dunlop 1944 and oswald 1985 in the second stage the firms determine the employment l which prevails until the next period in the third and final stage the local union negotiates with the management of the firm about local wage drift the total wage is w q wage drift the assumption that the firms determine employment prior to wage bargaining is used by e g moene 1987 and horn wolinsky 1985 both the central labor union and the firms know how local wage bargaining functions and can therefore perfectly anticipate what the result

insider effects in wage determination abstract the paper attempts to shed new light on the determinants of industry wages by a cross country comparison of wage setting relationships making use of comprehensive and consistent panel data on industries from the early 1960s to the mid 1980s the empirical analysis involves estimations of identically specified industry wage equations for each of five countries sweden norway finland germany and the united states a key finding is that industry wages in the u s are the most responsive to sectoral price and productivity changes by contrast industry wages in the nordic countries are largely unaffected by sectoral conditions the results cast doubt on the competitive model as an accurate characterization of wage setting under decentralization

do r d tax incentives lead to higher wages for r d workers evidence from the netherlands this paper examines the impact of the dutch r d tax incentive scheme on the wages of r d workers we construct firm specific r d tax credit rates that vary over time following variations in the dutch r d tax incentive program using instrumental variables we estimate a wage sharing model with an unbalanced firm level panel data covering the period 1997 2004 the elasticity of the r d wage with respect to the fraction of the wage supported by the fiscal incentives scheme is estimated at 0 2 in the short run and 0 24 in the long run

on the interaction between efficiency wages and union firm bargaining models even when efficiency wage considerations are taken into account firms may have no incentive to pay wages above the competitive minimum the total value of output therefore may be increased if workers in the efficiency wage sector also possess bargaining power efficiency wage and insider outsider models may also reinforce each other

wages policy and unemployment in australia it is generally accepted among australian economists that high rates of growth of wages at various times over the last decade have made the achievement of full employment and lower rates of inflation more difficult fear of a further acceleration of wage growth has also been a policy constraint it is when one attempts to go further that considerable disagreement becomes evident from a labour market viewpoint there does not seem to be a consensus as to the answers to the two broad questions that should be addressed first how important are wage changes relative to other factors that depress employment and add to the inflation rate second how does government policy impinge on the process that generates wage changes to do justice to both of these in a paper as short as this one is difficult so i shall focus most of the paper on the second question the relationships between government policy and wage changes are particularly important at this time for most of the last decade successive governments have operated a national wages policy which to a large degree has been based on the indexation of wages for past price changes the latest experiment the prices and incomes accord is the centrepiece of the current government s employment and inflation policy and after almost two years of wide community and media support the key principles upon which it is based are suddenly being questioned 1 our prime endeavour therefore will be to build up sufficient understanding of the wage determination process so that some evaluation can be made as to the effectiveness of these national wage policies this turns out to be a remarkably difficult task which generates considerable concern in our mind that the data may not be sufficiently rich to serve as a basis for sound judgments it does appear however that the effect of a given level of unemployment upon wage changes has consistently weakened over the last decade why this should be so is a major unresolved puzzle i offer a loosely constructed theory that is consistent with the facts but it is by no means the only possible explanation section i provides a description of wage setting in australia and some key facts of the economy in section ii the statistical analysis of wage changes focuses on two competing theories one is the phillips curve approach and the other stresses that wage outcomes may be to a significant degree independent of the level of unemployment and may depend instead on utilization rates of labour within the firm section iii considers the efficacy of incomes policies in australia some final comments areoffered in section iv

an investigation into the power of insiders in wage determination abstract this paper is concerned with the role of insider forces in wage determination various union and non union models of wage behaviour are considered and they imply that wages are a convex combination of internal and external factors certain union models also imply a degree of hysteresis data on fourteen british production industries reveal that i insider forces are important ii their importance is directly related to both union power and the degree of monopoly in the product market iii the state of the aggregate labour market is also important and iv hysteresis effects arising from insider power are only significant in a small minority of sectors
