to float or to fix evidence on the impact of exchange rate regimes on growth we study the relationship between exchange rate regimes and economic growth for a sample of 183 countries over the post bretton woods period using a new de facto classification of regimes based on the actual behavior of the relevant macroeconomic variables in contrast with previous studies we find that for developing countries less flexible exchange rate regimes are associated with slower growth as well as with greater output volatility for industrial countries regimes do not appear to have any significant impact on growth the results are robust to endogeneity corrections and a number of alternative specifications borrowed from the growth literature

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

estimating the impact of currency unions on trade solving the glick and rose puzzle does leaving a currency union reduce international trade this paper uses a historical approach to re examine the puzzling large apparent impact of currency unions on trade i find that the early time series estimates were driven by the gradual decaying of colonial trade ties and other major geopolitical factors including warfare communist takeovers and ethnic cleansing episodes my methodology which carries lessons for other uses of gravity equations in policy analysis yields point estimates of currency unions on trade that are not statistically distinct from zero

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

imperfect rent dissipation with unionized labor traditional rent seeking theory focused only on socially wasteful expenditures by firms competing for restrictive regulations more recently rent defending expenditures by consumers have also been taken into account this paper extends the analysis by adding rent sharing expenditures by organized labor the paper merges the tullock lottery model and the monopoly union model and considers both a costless and a costly wage bargaining mechanism the participation of consumers and workers in the distributional contest is shown to reduce rather than increase the social cost of restrictive regulations the participation of consumers and workers also raises the probability of deregulation

the dynamics of monopoly union wages with asymmetric information dunlop s 1994 work on the monopoly union model emphasizes that the primary role of wages is to distribute industry rents this paper extends the model to two periods and it is furthermore assumed that firms are better informed than workers about the size or quality of capital this variable is unchanged over time so the firm s first period action signals information relevant for the second period wage this dynamic relationship tends to lower labour demand in the first period

bilateral trade and the eurozone evidence from new member countries the question of whether and how much currency unions increase bilateral trade among their members has garnered much attention since rose s seminal article the answer is as pertinent now as ever for both the eurozone s existing and future members as the financial crisis shook the very foundations of the european monetary union emu and brought its shortcomings into the spotlight this paper analyses the issue using the gravity equation with country pair and time fixed effects for a sample of the four new members of the emu slovakia slovenia malta and cyprus which has to the author s knowledge not been studied thus far due to their recent joining and controls drawn from the european union this paper finds a positive relationship between joining the emu and trade with emu partners but not with non emu partners

productivity and distribution effects of codetermination in an efficient bargaining model codetermination can be regarded as an extreme regulatory intervention of the legislator in the labor market which might affect the efficiency of production and the bargaining power of labor based on a model that covers both efficient bargaining and employment bargaining a simple equation is derived that is suited to empirical testing the empirical test is based on german data and includes years before and after the extension of german codetermination law in 1976 the estimates determine the productivity of labor and relative bargaining power of capital and labor it turns out that codetermination does not affect productivity but leads to a significant increase in workers bargaining power and the distribution of rents

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

efficiency wages and x inefficiencies within most organizations agents may spend time on a variety of tasks productive and redistributive in this paper i derive an optimal multi task incentive scheme under the assumption that agents have limited liability the wage level is shown to increase with an agent s discretion and the organization s profits with multiple agents it is generally not optimal for the principal to fully eliminate distributional conflict within the organization the resulting influence costs constitute a measure of x inefficiency the analysis illuminates the relationship between competition and influence costs emphasizing the role of the organization s production technology

fair wages in the open economy we show how an extended theory of fair wages can be incorporated in the two by two heckscher ohlin model an important feature of the model is the existence of involuntary unemployment several results stand out first there is no longer a simple relatio

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

competition privatisation and productive efficiency evidence from the airline industry we use data from the airline industry to examine the extent to which the costs of airline operations are affected by rents accruing to workers and the extent to which these rents depend inter alia upon the degree of competition in the industry our empirical results based on a panel of twelve european and seven major united states airlines confirm that state ownership substantially increases rents to labour while the effects of competition are more subtle and ambiguous airline profits tend to be associated with higher rents to employees the gains from further privatisation and liberalisation may be quite large does competition have significant effects on productive as well as allocative efficiency convincing empirical answers to this question have been hard to find for two reasons first data of the quality required for robust estimation of productive efficiency are only rarely available secondly there is frequently no convincing standard against which the efficiency of an industry or a firm may be compared since when the degree of competition varies many other things such as technology network structures and firm sizes typically vary as well these problems do not automatically make comparison impossible but they compound the need for high quality data one industry which is likely to be well suited to investigating questions of this kind is the international airline industry the industry contains a large number of firms thus ensuring at least enough potential competition to make questions about the effects of competition interesting but the scope for these firms to compete with one another has been influenced to varying degrees over the years by different national and international regulatory regimes in particular deregulation of the united states industry in 1978 provided a kind of natural experiment that has led not only to comparisons of the before and after variety but also to comparisons between the united states industry and that of other global regions notably europe such comparisons are far from straightforward but they are facilitated by the fact that the technology of civil aviation is more or less internationally standardised and by the relatively high quality of available data in the industry

a biological basis for expected and non expected utility abstract a biological model is developed here to determine the fittest attitude to risk with a fixed environment the type maximizing expected offspring is selected this yields the expected utility theorem when translated into a criterion for evaluating gambles over commodities with a random environment however the type selected is strictly less averse to idiosyncratic risk than to risk which is correlated across all individuals the implied criterion for choice over gambles does not satisfy the expected utility theorem and may induce choice of a gamble which is first order stochastically dominated journal of economic literature classification number d81

alliances in the shadow of conflict victorious alliances often fight about the spoils of war this article presents an experiment on the determinants of whether alliances break up and fight internally after having defeated a joint enemy first if peaceful sharing yields an asymmetric rent distribution this increases the likelihood of fighting in turn anticipation of the higher likelihood of internal fight reduces the alliance s ability to succeed against the outside enemy second the option to make nonbinding nonaggression declarations between alliance members does not make peaceful settlement within the alliance more likely third higher differences in the alliance players contributions to alliance effort lead to more internal conflict and more intense fighting

financial integration gdp correlation and the endogeneity of optimum currency areas the paper analyses the relationship between trade financial integration and business cycle synchronization in the euro area the introduction of the euro has had a noticeable impact on european financial markets evidence that capital market integration exerts a positive effect on output correlation has two major implications first it corroborates the hypothesis of the endogeneity of optimum currency areas whereby after joining a monetary union countries better meet standard oca criteria second it provides european policy makers with yet another reason to pursue financial integration in the euro area and in prospective members as well

games of monetary and fiscal interactions in the emu abstract this paper constructs various models of the emu and ecb when member countries have different objectives voting in pursuit of national interest can yield moderate and stable inflation the metaphor of walsh type contracts implements a monetary policy rule that averages the member countries most preferred rules in a repeated relationship where a country suffering a large adverse shock can use political bargaining to subvert the ecb s commitment the optimal rule should incorporate some flexibility to forestall that finally freedom of national fiscal policies undermines the ecb s monetary commitment this may justify fiscal constraints like the stability and growth pact

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

out in the cold iceland s trade performance outside the european union and european monetary union although entering currency and customs unions involve both costs and benefits an increasing body of research is finding that the benefits in terms of international trade creation are remarkably large focusing simply on the european monetary union emu rather than the broad range of currency unions studied by other authors we find that the trade impact of emu is smaller but still substantial our findings suggest that the iceland s trade could increase by about 60 and that the trade to gdp ratio could rise by 12 percentage points should iceland join the european union and emu copyright 2006 oxford university press

an introduction to the wage curve en conomists and policymakers are interested in understanding the forces that determine the level of unemployment and the level of wages this paper describes an empirical discovery made with the help of international microeconometric evidence covering more than a dozen nations about a link between these two variables the connection can be portrayed on a graph with the level of unemployment on the horizontal axis and the level of wages on the vertical axis then the wage curve as shown in figure 1 is a downwardsloping locus this relationship tells us that holding others things constant if a region has a rise in unemployment in a particular year those who live there will have a fall in their wages in that year what does this curve mean how in a field where fully controlled experiments are almost impossible could there be any convincing scientific basis for this wage curve what is the relationship between the wage curve and a phillips curve other than that the curve of figure 1 looks like a phillips curve with the vertical axis mislabeled how does the wage curve fit into existing economic knowledge and is the empirical finding consistent with competitive theory this paper sketches answers to these kinds of questions the discussion draws on our book the wage curve blanchflower and oswald 1994 where the points raised here are investigated more fully it also rests upon work done by other economists whose work is listed in the paper and the bibliography

endogenous oca analysis and the early euro experience some have argued that the endogenous responses to the formation of a currency area are so strong that one need not worry about optimum currency area conditions ex ante we argue that this is much too strong a conclusion we draw on a number of recent studies to evaluate the endogeneity experiences of the eurozone in three major areas trade flows business cycle synchronisation and structural reforms to improve labour and product market flexibility simple before and after comparisons are insufficient for analysis of endogeneity the experiences of non euro western european economies suggest that broader trends also had considerable influence on trade and business cycle patterns while trade rose substantially within the eurozone it also rose with and among other european economies we argue that political economy considerations tend to dampen the magnitude of endogeneity efforts on structural reforms and that meeting conditions for entry may be a more powerful mechanism in this than are subsequent endogenous responses we also discuss a number of areas for further research

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

workers of the world unite franchise extensions and the threat of revolution in europe 1820 1938 abstract we test the hypothesis that the extension of the voting franchise in europe was related to the threat of revolution we contend that international diffusion of regime contention and information about revolutionary events happening in neighboring countries generate the necessary variation in the perceived threat of revolution using two samples of european countries covering the period from 1820 to 1938 we find robust evidence which is consistent with the threat of revolution hypothesis we also find some evidence that war triggered suffrage reform

contractual wages and the wage cushion under different bargaining settings how does a typically european bargaining system with collective bargaining and national minimum wage coexist with low unemployment and high wage flexibility a unique data set on workers firms and collective bargaining contracts in portugal is used to analyze the determinants of both the contractual wage and the wage cushion difference between contractual and actual wages the results indicate that the wage cushion stretches the returns to worker and firm attributes whereas it shrinks the returns to union power therefore firm specific arrangements partly offset collective bargaining granting firms certain freedom when setting wages contractual wages reflect trade unions egalitarian policy

trade creation and diversion revisited accounting for model uncertainty and natural trading partner effects summary the effect of preferential trade agreements ptas on trade flows is subject to model uncertainty stemming from the diverse and even contradictory effects suggested by the theoretical pta literature the existing empirical literature has produced remarkably disparate results and the wide variety of empirical approaches reflects the uncertainty about the correct set of explanatory variables that ought to be included in the analysis to account for the model uncertainty that surrounds the validity of the competing pta theories we introduce bayesian model averaging bma to the pta literature statistical theory shows that bma successfully incorporates model uncertainty in linear regression analysis by minimizing the mean squared error and by generating predictive distributions with optimal predictive performance once model uncertainty is addressed as part of the empirical strategy we find strong evidence of trade creation trade diversion and open bloc effects our results are robust to a range of alternative empirical specifications proposed by the recent pta literature copyright 2010 john wiley sons ltd

one money one market the effect of common currencies on trade currency unions their dramatic effect on international trade a gravity model is used to assess the separate effects of exchange rate volatility and currency unions on international trade the panel data bilateral observations for five years during 1970 90 covering 186 countries includes 300 observations in which both countries use the same currency i find a large positive effect of a currency union on international trade and a small negative effect of exchange rate volatility even after controlling for a host of features including the endogenous nature of the exchange rate regime these effects statistically significant imply that two countries sharing the same currency trade three times as much as they would with different currencies currency unions like the european emu may thus lead to a large increase in international trade with all that that entails andrew rose

rent sharing holdup and wages evidence from matched panel data rent sharing by workers can reduce the incentives for investment if some of the returns to sunk capital are captured in higher wages we propose a simple measure of this holdup effect based on the size of the wage offset for firm specific capital accumulation using social security earnings records for workers in the veneto region of italy linked to detailed financial data for their employers we find strong evidence of rent sharing with an elasticity of wages with respect to potential rents per worker of around 4 arising mainly at larger firms with higher price cost margins on the other hand we find little evidence that bargaining lowers the return on investment instead firm level bargaining appears to split the rents after deducting the full cost of capital

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

a test of competitive labor market theory the wage structure among care assistants in the south of england this paper examines the structure of wages in a very specific labor market care assistants in residential homes for the elderly on england s sunshine coast this sector corresponds closely to economists notion of what should be a competitive labor market both because it has a large number of small firms undertaking a very homogeneous activity in a concentrated geographical area and because the workers are neither unionized nor covered by any minimum wage legislation so that there are effectively no external constraints on the wage setting process the authors find that the wage structure deviates in important respects from what would be expected in a competitive labor market in particular wage dispersion is small within firms but large between firms and the wage dispersion that is present does not seem to be closely related to workers productivity related characteristics a test rejects the hypothesis that unobserved labor quality can explain these findings

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

currency unions and irish external trade ireland has participated in two currency unions a bilateral union with the uk that lasted until 1979 and as a founder member of european monetary union emu that began in 1999 this article investigates whether currency unions have influenced irish trade patterns

long run growth and volatility which source really matters the aim of the article is to analyse the relationship between long run growth and business cycle volatility in particular the main purpose of this article is to identify which source of volatility is most detrimental to growth using cross country data from 1970 to 2000 and several indicators of volatility such as inflation exchange rate government expenditure output and investment volatility this article shows that although all these measures of volatility are remarkably harmful for growth business cycle investment volatility is the main source that hampers long run growth this relation is robust to different measures of business cycle and to different sub samples of countries

north south and distance in the gravity model abstract it is generally assumed that distance in the gravity model strictly reflects frictions impeding bilateral trade however distances north south could also reflect differences in factor endowment that provide opportunities for profitable trade this paper investigates the hypothesis that if we control for distance in the ordinary sense differences north south promote international trade the hypothesis receives ample support moreover the significance of differences north south survives a battery of robustness tests concerning period distinctions between differences in latitude north north north south and south south and controls for other measures of differences in factor endowment such as differences in per capita output and differences in average temperature rainfall and seasonal range in temperature the impact of differences north south on bilateral trade has also been falling this decline in turn might be partly responsible for the weakening of the influence of distance that has been occurring since world war ii this last hypothesis receives confirmation as well finally the paper examines the impact of internal distance and remoteness on trade since both variables are country specific this is done by studying their impact on the country fixed effects themselves in the earlier estimates internal distance turns out to have a far greater impact than remoteness by an order of 10

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

nash equilibrium and the evolution of preferences abstract a population of players is randomly matched to play a normal form game g the payoffs in this game represent the fitness associated with the various outcomes each individual has preferences over the outcomes of the game and chooses an optimal action with respect to those preferences however these preferences need not coincide with the fitness payoffs when evolution selects individuals on the basis of the fitness of the actions they take the distribution of aggregate play must be a nash equilibrium of g weak additional assumptions on the evolutionary process imply perfect equilibrium journal of economic literature classification number c72

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

on the evolutionary stability of altruistic and spiteful preferences abstract this note demonstrates that a result on evolutionary stability presented by bester and guth bester h guth w 1998 journal of economic behavior and organization 34 193 209 applies under more general preference and payoff functions

the role of unemployment in wage determination further evidence on the wage curve from turkey this paper presents an empirical estimation of the correlation between wages and regional unemployment rates in turkey more specifically it explores the role of regional unemployment rates in wage determination the analysis builds upon a series of recent empirical studies on the wage unemployment relationship now commonly known as the wage curve a downward sloping curve in wage unemployment space the existing studies are for most part in advanced market economies while this paper presents one of the few attempts at a wage curve analysis within the context of a developing market economy a cross sectional estimation of micro level individual wage data for the turkish labour market in 1994 suggest a statistically significant negative correlation between wages and regional unemployment rates separate regressions for men and women however show a wage curve to exist only in the male labour market the study also presents the results on other variables of wage determination such as returns to school

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

evolution of time preference by natural selection this paper entertains the hypothesis that human time preferences are in evolutionary equilibrium i e that no mutation changing time preferences could be favored by natural selection this hypothesis implies that the marginal rate of substitution mrs holding darwinian fitness constant must equal the mrs holding utility constant furthermore in a market economy the latter must equal the mrs in exchange exploiting these principles the author finds that the long term real interest rate should equal ln 2 per generation about 2 percent per year and that young adults should discount the future more rapidly than their elders copyright 1994 by american economic association

micro foundations for wage flexibility wage insurance at the firm level to what extent do firms insulate their workers wages from fluctuations in product markets which firm and worker attributes are associated with wage flexibility at the micro level we first rely on guiso pistaferri and schivardi 2005 to estimate dynamic models of sales and wages finding that in portugal workers wages respond to permanent shocks on firm performance as opposed to transitory shocks we then explore the factors associated with wage flexibility finding that collective bargaining and minimum wages are associated with higher wage insurance by the firm while the threat of firm bankruptcy reduces it managers receive less protection against permanent shocks than other workers

the evolution of preferences and competition a rationalization of veblen s theory of invidious comparisons we examine how preferences evolve by natural selection in a competitive environment similar to that characterizing much of our evolutionary past we find that the evolutionarily stable preferences in this context exhibit a concern not only for absolute payoffs but also for relative payoffs and that this intensifies the degree of competition relative to what obtains when players consider only absolute payoffs we argue that this has consequences for the equilibrium population size we argue that the premise of this analysis is consistent with the available anthropological evidence and that the prediction is broadly consistent with the findings of experimental game theory

insurance within the firm we evaluate the allocation of risk between firms and their workers using matched employer employee panel data unlike previous contributions this paper focuses on idiosyncratic shocks to the firm which are the correct empirical counterpart of the theoretical notion of diversifiable risk we allow for both temporary and permanent shocks to output and find that firms absorb temporary fluctuations fully but insure workers against permanent shocks only partially risk sharing considerations can account for about 15 percent of overall earnings variability the remainder originating from idiosyncratic shocks to individual workers our welfare calculations indicate that firms are an important vehicle of insurance provision

ramsey monetary policy with labor market frictions abstract traditional new keynesian models prescribe that optimal monetary policy should aim at price stability in the absence of a labor market frictions the monetary authority faces no unemployment inflation trade off the design of optimal monetary policy is analyzed here for a framework with sticky prices and matching frictions in the labor market optimal policy features deviations from price stability in response to both productivity and government expenditure shocks when the hosios 1990 on the efficiency of matching and related models of search and unemployment review of economic studies 57 2 279 298 condition is not met search externalities make the flexible price allocation unfeasible optimal deviations from price stability increase with workers bargaining power as firms incentives to post vacancies fall and unemployment fluctuates above the pareto efficient one

us and them the origin of identity and its economic implications we investigate the origins of identity and the innate proclivity to draw a distinction between insiders and outsiders we propose an evolutionary explanation we argue that identity arises because it facilitates survival in an evolutionary setting we endogenize preferences and demonstrate that the evolutionarily stable preferences fashioned by natural selection would draw a distinction between insiders and outsiders we then work out the implications of such preferences in two contemporary scenarios one entailing rent seeking behavior and the other involving public good provision our results are in conformity with empirical evidence

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

on the evolution of prize perceptions in contests abstract we apply an indirect evolutionary approach to players perceived prize valuations in contests evolution in finite populations leads to preferences that overstate the prize s material value and induce overexpenditure we establish an equivalence between evolutionarily stable strategies and the behavior induced by evolutionarily stable preferences

distance language religion and the law of one price evidence from canada and nigeria we examine the impact of physical distance language and religion on law of one price lop deviations across interwar canadian and modern nigerian cities the data comprise monthly average retail prices for narrowly defined goods collected by national statistical agencies we find that differences in the fraction of the city population sharing a common language and religion have a significant impact on lop deviations the impact of language differences is consistent with a recently developed theory in which both trade costs and differences in signal noise ratios contribute to lop deviations

evolution of preferences we endogenize preferences using the indirect evolutionary approach individuals are randomly matched to play a two person game individual subjective preferences determine their behaviour and may differ from the actual objective pay offs that determine fitness matched individuals may observe the opponents preferences perfectly not at all or with some in between probability when preferences are observable a stable outcome must be efficient when they are not observable a stable outcome must be a nash equilibrium and all strict equilibria are stable we show that for pure strategy outcomes these conclusions are robust to allowing almost perfect and almost no observability with the notable exception that inefficient strict equilibria may fail to be stable with any arbitrarily small degree of observability despite being stable with no observability

exchange rate regimes and international trade evidence from the classical gold standard era in this paper we show that the spread of the classical gold standard in the late nineteenth century increased international trade flows this positive effect was compounded whenever a group of countries formed a monetary union applying the gravity model of trade to more than 1 100 country pairs during the 1870 1910 period we find that two countries on gold would trade 60 percent more with each other than with countries on a different monetary standard moreover a monetary union would more than double bilateral trade flows our findings are relevant for current discussions on alternative monetary arrangements for the twenty first century

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

evolution in economic games abstract this paper examines the conditions under which evolutionary processes select equilibrium strategies of agents or firms under plausible dynamics optimal selection takes place provided that economic agents are small relative to the environment that is each such agent has a negligible effect on others payoffs however when this assumption is not met survival need not imply optimality examples in the contexts of bargaining bidding and market competition are presented

the size and sources of economic rents in a developing country manufacturing labour market the potential sources of rent to labor in a developing country urban labor market are considered in this paper the data set used enables the relative importance of unions firm size profitability ownership and firm age to be assessed on the basis of cross section evidence it is shown that all these factors affect earnings a panel data based estimation of the importance of the profitability term provides strong support for a rent sharing theory of wage determination in a developing country similar to much recent evidence for developed country labor markets copyright 1996 by royal economic society

emu and trade revisited long run evidence using gravity equations in this paper we present evidence of the long run effect of the euro on trade for the twelve initial emu countries for the period 1967 2008 from a double perspective first we pool all the bilateral combinations of trade flows among the emu countries in a panel cointegration gravity specification second we estimate a gravity equation for each of the emu members vis a vis the other eleven partners we apply panel cointegration techniques based on factor models that account for cross dependence and structural breaks whereas the joint gravity equation provides evidence on the aggregate effect of the euro on intra european trade by isolating the individual countries we assess which of the member countries have obtained a larger benefit from the euro the results show that the euro has had a positive though small effect on trade belgium and luxembourg france and italy are the countries more benefited from the introduction of the euro the effects for exports to third countries are in general more moderate and with the exception of greece there is no evidence of diversion effects

the evolutionary logic of honoring sunk costs i introduction economists claim that sunk costs should not figure in current decision making because by definition these expenditures cannot be retrieved and should be treated as bygones but there is a large literature both experimental and anecdotal in which people are observed to waste resources by honoring bygones that could not possibly make them better off see e g arkes and blumer 1985 arkes and ayton 1999 mcafee mialon and mialon 2010 thaler 1980 such excess in wasting resources is unlikely to have been tolerated by nature in the process of evolution if it did not serve some purpose to enhance fitness in our remote past the purpose of this study is to suggest such a function whereby evolutionary processes have hardwired a concern for sunk costs in human decision making 1 the concept of honoring sunk costs has been referred to in the literature as the concorde fallacy 2 arkes and blumer 1985 have a number of other examples of good money being thrown after bad economists have provided various explanations for why sunk costs appear salient to humans kanodia bushman and dickhaut 1989 and prendergast and stole 1996 propose a theory where reputational effects make agents unwilling to change their decisions mcafee mialon and mialon 2010 have suggested several models involving information content reputation or constraints on decision making that provide rational reasons for taking sunk costs into account likewise baliga and ely 2011 have proposed a model in which sunk costs may acquire salience as a memory kludge because they may contain information about the value of a project previously initiated but whose value has now been forgotten carmichael and macleod 2003 have proposed a model where in a bilateral bargaining situation the norm of taking account of sunk costs resolves the hold up problem that typically results in underinvestment thaler 1980 arkes and blumer 1985 and whyte 1986 suggested a prospect theory approach to understanding sunk cost effects arkes and blumer 1985 the philosopher nozick 1993 and others have argued that honoring sunk costs can alleviate problems of time inconsistency and temptation john may believe that going to the theater is a good thing but when the time comes he cannot rouse himself to do so because it would require relinquishing whatever else appears appealing at the time to circumvent this john buys tickets in advance as a precommitment device but to do this he must believe in the first place that his future self is going to honor sunk costs 3 whatever the reason for the time inconsistent preferences say hyperbolic discounting the honoring of sunk costs may be used to remedy the problem of time inconsistency but nozick for example offers no reason for why sunk costs are honored in the first place we offer an evolutionary reason to suggest why nature may have hardwired a proclivity in humans to honor sunks costs a reason that differs from those offered in the articles cited above we propose that the built in salience of sunk costs is an adaptation to the problem of self control self control problems may arise in decision making because contrary to our untutored perceptions the human brain has a triune 4 rather than a unitary structure maclean 1989 panksepp 1998 because of the way the brain has evolved different regions within it defined by their own neuroanatomical and neurochemical features deal with different aspects of action and behavior although interconnected through chemical and neuronal pathways the different control centers tend to act autonomously and may conflict in their responses to stimuli when the emotional or motivational centers which lie in the sub cortical limbic system push us to certain actions that the rational persona in the cortex wishes to deny there is a conflict and the problem of self control arises panksepp 1998 301 notes

the nonlinear impact of currency unions on bilateral trade abstract most gravity model specifications assume that a currency union varies the level of bilateral trade between members by a constant proportion we demonstrate that a common currency also alters the slope of the relationship between bilateral trade and member country gdps

the strategic advantage of interdependent preferences in rent seeking contests we study rent seeking contests where the set of players contains two groups of players one with independent preferences and the other with negatively interdependent preferences it turns out that the latter experience a strategic advantage in general two player contests and in n player contests with non increasing marginal efficiency for general n player contests with increasing marginal efficiency the strategic advantage prevails provided convexity of contest technologies is sufficiently weak for strongly convex contest technologies other types of equilibria exist including one where individualists receive strictly higher pay off

excessive wages and the return on capital received wisdom suggests that excessive wages defined as the part of real wages that do not follow labour productivity developments are adversely associated with the return on capital this paper argues that excessive wages and profits are better thought of as responses to changes in the economic political and institutional environment and there is no a priori reason for a negative relationship between them we thus investigate whether there is a causal effect of excessive wages on capital return using aggregate panel data for 19 oecd countries for the period 1970 2000 we account for the endogeneity of excessive wages by exploiting variations in institutional and labour market characteristics our main finding is that excessive wages do not affect the return on capital this result remains robust to alternative empirical specifications and to alternative definitions of profitability and excessive wages and questions the standard advice by international economic organizations on wage moderation copyright the author 2011 published by oxford university press on behalf of the cambridge political economy society all rights reserved oxford university press

trade costs 1870 2000 what has driven trade booms and trade busts in the past century and a half was it changes in global output or in the costs of international trade to address this question we derive a micro founded measure of aggregate bilateral trade costs based on a standard model of trade in differentiated goods these trade costs gauge the difference between observed bilateral trade and frictionless trade in terms of an implied markup on retail prices of foreign goods thus we are able to estimate the combined magnitude of tariffs transportation costs and all other macroeconomic frictions that impede interna tional trade but that are inherently difficult to observe we use this measure to examine the growth of global trade between 1870 and 1913 its retreat from 1921 to 1939 and its subsequent rise from 1950 to 2000 we find that trade cost declines explain roughly 55 percent of the pre world war i trade boom and 33 percent of the post world war ii trade boom while a precipi tous rise in trade costs explains the entire inter

wages and unemployment in an urban african labour market this paper argues that urban labor markets in africa exhibit a wage curve similar to those found in the united states britain canada and other developed countries drawing on data from the ivory coast the author finds that urban wages are depressed by higher levels of unemployment this result is robust to changes in model specification and level of aggregation it is consistent with the model of wage determination developed by c shapiro and j stiglitz 1984 and d blanchflower and a oswald 1995 but not with claims that urban wages are invariant to unemployment copyright 1996 by royal economic society

are profit maximisers the best survivors a darwinian model of economic natural selection abstract this paper demonstrates that the friedman conjecture that profit maximisation summarises appropriately the conditions for firm survival is not generally true if firms have market power profit maximisers are not necessarily the best survivors because of the possibility of spiteful behaviour of the following kind say a firm forgoes profit maximisation and thus decreases its survival chances but its deviation from maximisation harms its profit maximising competitors more than itself though the firm will be less likely to survive than it would if it maximised its profits it will still be more likely to survive than its competitors

who profits from patents rent sharing at innovative firms this article analyzes how patent induced shocks to labor productivity propagate into worker compensation using a new linkage of u s patent applications to u s business and worker tax records we infer the causal effects of patent allowances by comparing firms whose patent applications were initially allowed to those whose patent applications were initially rejected to identify patents that are ex ante valuable we extrapolate the excess stock return estimates of kogan et al 2017 to the full set of accepted and rejected patent applications based on predetermined firm and patent application characteristics an initial allowance of an ex ante valuable patent generates substantial increases in firm productivity and worker compensation by contrast initial allowances of lower ex ante value patents yield no detectable effects on firm outcomes patent allowances lead firms to increase employment but entry wages and workforce composition are insensitive to patent decisions on average workers capture roughly 30 cents of every dollar of patent induced surplus in higher earnings this share is roughly twice as high among workers present since the year of application these earnings effects are concentrated among men and workers in the top half of the earnings distribution and are paired with corresponding improvements in worker retention among these groups we interpret these earnings responses as reflecting the capture of economic rents by senior workers who are most costly for innovative firms to replace

signalling ability to pay and rent sharing dynamics abstract it is often argued that competitive and rent sharing models of wage determination should be distinguished by their long run properties in general rent sharing models predict the existence of a long run relationship between wages and firm specific ability to pay but the competitive model does not i present a two period counter example which demonstrates that rent sharing can be merely a short run phenomenon in the separating equilibria the firm signals ability to pay through first but not second period wage offers the model also has pooling equilibria in which the firm pays rents in the long run

resource grabbing by status conscious agents abstract we introduce a dynamic model of resource grabbing by status conscious agents i e agents value not only their absolute consumption levels but also the relative status within their reference group we explore the effect of the concern for relative consumption on the growth rate and the welfare of an economy where agents appropriate from a common property resource our model shows that the greater is agents concern about their relative status the more aggressively they tend to behave consequently social welfare is lower because the growth rate of the public asset is reduced due to higher extraction rate we also consider the effect of increased heterogeneity and show that social welfare decreases as the distribution of status consciousness among agents widens

rank as an inherent incentive evidence from a field experiment abstract money is the prime incentive considered in economic models however recent evidence indicates that people are also greatly concerned about their social rankings is this solely because rank brings tangible benefits or because in addition people have an inherent preference for high rank this paper deployed a field experiment that provides evidence for an inherent preference in the experiment vietnamese students enrolled in an english course performed significantly better on the official standardized international final test when they were told their rankings on practice tests than when they were not this result held even when this ranking information could not be reliably communicated thus severely attenuating the potential to bring tangible or status benefits

malthusian selection of preferences the authors study natural selection of preferences using a golden age model with endogenous population in equilibrium all agents have preferences with maximum biological fitness given resource constraints and total population is the maximum the environment can sustain naturally selected agents follow the golden rule acting as if they maximize the undiscounted sum of per capita felicities of current and future generations selected preferences and hence work saving consumption and population density vary predictably with environmental differences copyright 1990 by american economic association

efficiency wages revisited the internal reference perspective the missing wage rigidity in general equilibrium models of e ciency wages is an artifact of the external wage reference perspective conventionally adopted by the literature e ciency wage models based on an internal perspective in which the wage reference is made dependent on the flrm s ability to pay are capable of generating strong wage rigidity this paper makes the point in the context of the gift exchange framework originally proposed by akerlof 1982 jel classiflcation e24 e32 j50

a multisectorial matching model of unions abstract we develop an equilibrium matching model where unions have an important institutional presence monopolistic competition characterizes the goods market where only some sectors are unionized thus the model can vary the coverage of collective bargaining it can vary the degree of coordination between unions and alternatively consider national and sectorial unions calibration to the union premium implies a workers rent extraction parameter much lower than assumed in the matching literature we introduce unemployment insurance to study the interactions of policies with unions and find that unions only push for more generous benefits if this does not entail higher payroll taxes

the mirage of exchange rate regimes for emerging market countries this paper argues that much of the debate on choosing an exchange rate regime misses the boat it begins by discussing the standard theory of choice between exchange rate regimes and then explores the weaknesses in this theory especially when it is applied to emerging market economies it then discusses a range of institutional traits that might predispose a country to favor either fixed or floating rates and then turns to the converse question of whether the choice of exchange rate regime may favor the development of certain desirable institutional traits the conclusion from the analysis is that the choice of exchange rate regime is likely to be of second order importance to the development of good fiscal financial and monetary institutions in producing macroeconomic success in emerging market countries this suggests that less attention should be focused on the general question whether a floating or a fixed exchange rate is preferable and more on these deeper institutional arrangements a focus on institutional reforms rather than on the exchange rate regime may encourage emerging market countries to be healthier and less prone to the crises that we have seen in recent years

the myth of decoupling the decoupling hypothesis is the idea that business cycles in emerging market economies have become more independent from business cycles in advanced economies in recent years decoupling essentially amounts to a structural break in the degree of business cycle interdependence between the two groups of economies and it can be tested as such we develop an innovative measure of business cycle interdependence based on the euclidean distance available at the annual frequency which allows for a proper test for a structural break in a graphical setup we also make use of a standard econometric test both approaches point to the same conclusion there has been no decoupling in recent years if anything the degree of business cycle interdependence has become stronger

disaggregated trade and disaggregated currency unions a ranking of common currency effects andrew rose has long argued that a common currency has a large effect on increasing trade recently rose has called into question the reliability of this conclusion as new techniques have emerged for estimating gravity equations this article uses the sector specific gravity model developed by anderson and yotov 2010a to investigate if disaggregated trade can provide a reliable estimate of a common currency s effect disaggregating trade alone is insufficient to obtain a reliable estimate of a currency union regardless of econometric technique when the effect of a common currency on trade is uniform across all unions disaggregating the universe of currency unions with individual effects provides a reliable ranking of currency unions independent of estimation method by the effect that each union s currency has on increasing trade these rankings differ across sectors

the incidence and intensity of wage indexation an empirical analysis variables suggested by theoretical studies of indexation are considered with a view to examining their utility in the context of the decision to index incidence and the desired degree of indexation when escalator clauses are put into effect intensity the tobit model which can address both of these issues suggests that most of the effects of explanatory variables on the regressand occur by modifying the incidence of indexation not its intensity however the tobit model is itself rejected in favour of separate probit and truncated regression investigations of incidence and intensity respectively the results obtained indicate that the standard list of explanatory variables which one thinks of in the context of the theoretical literature as dealing primarily with intensity perform well in explaining incidence but very poorly in accounting for the non limit observations the latter are influenced by bargaining power proxies such as the unemployment rate and union density a very clear trade off be

has the euro changed the business cycle abstract in contrast to the notion that the exchange rate regime is non neutral there is little evidence that emu has systematically changed the european business cycle in fact we find the volatility of macroeconomic variables largely unchanged before and after the introduction of the euro exceptions are a strong decline in real exchange rate volatility and a considerable increase in cross country correlations to account for this finding we develop a two country business cycle model which is able to replicate key features of european data in particular the model correctly predicts a limited effect of emu on standard business cycles statistics however further analysis reveals that the euro has changed the nature of the cycle through its impact on the transmission mechanism cross country spillovers have become relatively more domestic shocks relatively less important in accounting for economic fluctuations under emu this explains why there is little change in unconditional volatilities

last place aversion evidence and redistributive implications we present evidence from laboratory experiments showing that individuals are last place averse participants choose gambles with the potential to move them out of last place that they reject when randomly placed in other parts of the distribution in modified dictator games participants randomly placed in second to last place are the most likely to give money to the person one rank above them instead of the person one rank below last place aversion suggests that low income individuals might oppose redistribution because it could differentially help the group just beneath them using survey data we show that individuals making just above the minimum wage are the most likely to oppose its increase similarly in the general social survey those above poverty but below median income support redistribution significantly less than their background characteristics would predict jel codes h23 d31 c91
