digital labor market intermediation and job expectations evidence from a field experiment subjective expectations are fundamental for understanding individual behavior yet little is known about how individuals use new information to formulate and update their subjective expectations in this study we exploit data from a multi treatment field experiment to investigate how job market information sent to jobseekers via short text messages sms influence subjective job gain expectations in peru results show that jobseekers who received digital intermediation based on a large information set increased their before after job gain expectations relative to the control group independently of the information channel no significant effects were found when labor market intermediation is based on a restricted short set of information

industrial pollution abatement the impact on balance of trade this paper uses an ex post partial equilibrium framework to measure the impact of marginal changes in industrial p ollution abatement costs on the u s balance of trade in general and balance of trade with canada in particular the impacts are found to be negative for most industries growing with trade volume and smal l relative to domestic consumption in addition some evidence is fou nd that pollution control programs have changed the u s comparative advantage such that more high abatement cost goods are imported and m ore low abatement cost goods are exported

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

the north south divide questions of existence and stability this paper investigates the relationship between regional earnings and unemployment by use of information primarily from the general household surveys of 1975 and 1982 conventional earnings functions are augmented to capture the effects of the level and duration of unemployment and of regional differences in living costs in common with previous studies the authors find personal characteristics and the occupation or industry of employment to be important in earnings determination in this paper however they generally find that although higher unemployment is associated with reduced regional earnings ceteris paribus long term unemployment has little influence in regional earnings determination copyright 1990 by royal economic society

local pay determination theoretical models of local pay are reviewed ranging from neoclassical perspectives unemployment wage trade off models and segmented labor market approaches the empirical work on u s north south differentials is discussed for the u k studies of the extent of and trends in geographical pay differentials are considered as well as behavioral explanations focusing on the role of excess demand the issue of adjustment processes is then discussed both in theory and in relation to empirical work for the u s and u k this discussion focuses largely on geographical spillover effects in terms of origins evidence and issues of identification finally the impact of certain impediments in the adjustment process are considered specifically in relation to the u k these concern the role and influence of national wage bargaining as well as factors inhibiting labor migration stemming from the housing market and the climate of the national labor market copyright 1992 by blackwell publishers ltd

nash bargaining with downward rigid wages abstract we study the effect of downward wage rigidity in a dynamic model when wages are negotiated according to nash bargaining downward rigidity causes a decrease in the worker s expected utility for the firms the effect is ambiguous

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

unemployment and domestic violence theory and evidence is unemployment the overwhelming determinant of domestic violence that many commentators expect it to be the contribution of this paper is to examine theoretically and empirically how changes in unemployment affect the incidence of domestic abuse the key theoretical prediction is that male and female unemployment have opposite signed effects on domestic abuse an increase in male unemployment decreases the incidence of intimate partner violence while an increase in female unemployment increases domestic abuse combining data on intimate partner violence from the british crime survey with locally disaggregated labor market data from the uk s annual population survey we find strong evidence in support of the theoretical prediction

the impact of job security on job satisfaction in economic contractions versus expansions job security often measured using the perceived risk of job loss in the near future is a significant determinant of job satisfaction we posit that the impact job security has on job satisfaction is not only a function of how likely it is that a worker loses a job but also how likely it is that a worker could find another the effect this has on worker job satisfaction then is different depending on whether perceived job loss occurs or not when job openings are scarce or when job openings are plentiful we use difference in differences analysis of the 1997 and 2008 waves from the national study of the changing workforce to show that three measures of job security increase private sector worker job satisfaction and reduce worker incentives to quit more when job openings are relatively scarce during contractions than when job openings are relatively plentiful during expansions we find that our results are strongest among less educated workers

an econometric view on the estimation of gravity models and the calculation of trade potentials this paper presents an ar 1 model in the spirit of hausman and taylor zero differences between actual and in sample predicted trade flows large systematic differences between observed and in sample predicted trade flows only indicate model misspecification and econometric problems out of sample predictions make sense if countries of interest are in an early stage of the transformation process the gravity model remains an interesting tool for the calculation of counterfactuals e g the impact of catching up in gdp per capita in the ceec or of the reduction of trade costs via infrastructure investments or tariffs on bilateral trade etc for this line of research the difference between short term and long term influences could provide interesting insights

testing mixed strategy equilibria when players are heterogeneous the case of penalty kicks in soccer the concept of mixed strategy is a fundamental component of game theory and its normative importance is undisputed however its empirical relevance has sometimes been viewed with skepticism the main concern over the practical usefulness of mixed strategies relates to the indifference property of a mixedstrategy equilibrium in order to be willing to play a mixed strategy an agent must be indifferent between each of the pure strategies that are played with positive probability in the mixed strategy as well as any combination of those strategies given that the agent is indifferent across these many strategies there is no bene t to selecting precisely the strategy that induces the opponent to be indifferent as required for equilibrium why an agent would in the absence of communication between players choose exactly one particular randomization is not clear of course whether agents in real life actually play nash equilibrium mixed strategies is ultimately an empirical question the evidence to date on this issue is based almost exclusively on laboratory experiments e g barry o neill 1987 amnon rapoport and richard b boebel 1992 dilip mookherjee and barry sopher 1994 jack ochs 1995 kevin a mccabe et al 2000 the results of these experiments are mixed o neill 1987 concludes that his experimental evidence is consistent with nash mixed strategies but that conclusion was contested by james n brown and robert w rosenthal 1990 with the exception of mccabe et al 2000 which looks at a three person game the other papers generally reject the nash mixedstrategy equilibrium while much has been learned in the laboratory there are inherent limitations to such studies it is sometimes argued that behavior in the simpli ed arti cial setting of games played in such experiments need not mimic real life behavior in addition even if individuals behave in ways that are inconsistent with optimizing behavior in the lab market forces may discipline such behavior in the real world finally interpretation of experiments rely on the assumption that the subjects are maximizing the monetary outcome of the game whereas there may be other preferences at work among subjects e g attempting to avoid looking foolish that distort the results tests of mixed strategies in nonexperimental data are quite scarce in real life the games played are typically quite complex with large strategy spaces that are not fully speci ed ex ante in addition preferences of the actors may not be perfectly known we are aware of only one paper in a similar spirit to our own research using data from classic tennis matches mark walker and john wooders 2001 test whether the probability the player who serves the ball wins the point is equal for serves to the right and chiappori department of economics university of chicago 1126 east 59th street chicago il 60637 levitt department of economics university of chicago groseclose graduate school of business stanford university 518 memorial way stanford ca 94305 the paper was presented at games 2000 in bilbao and at seminars in paris and chicago we thank d braun j m conterno r guesnerie d heller d mengual p reny b salanie and especially j l ettori for comments and suggestions and m mazzocco and f bos for excellent research assistance any errors are ours 1 the theoretical arguments given in defense of the concept of mixed strategy equilibria relate either to puri cation john c harsanyi 1973 or to the minimax property of the equilibrium strategy in zero sum games for recent elaborations on these ideas see authur j robson 1994 and phil reny and robson 2001 2 the ultimatum game is one instance in which experimental play of subjects diverges substantially from the predicted nash equilibrium robert slonim and alvin e roth 1998 demonstrate that raising the monetary payoffs to experiment participants induces behavior closer to that predicted by theory although some disparity persists

fear unemployment and migration we examine the impact on the uk economy of the flow of workers from ten east european countries after their accession to the european union we find evidence that those most susceptible to competition from these workers have seen weaker wage inflation we document that the presence of these foreign workers has increased the fear of unemployment and helped to contain wage pressure we argue that this inflow of workers has increased supply by more than it has raised demand and thus had the effect of reducing both inflationary pressures and the natural rate of unemployment the recent rise in migration to the uk from eight eu accession countries the czech republic estonia hungary latvia lithuania poland slovakia and slovenia the a8 countries which started in 2004 as well as subsequently from romania and bulgaria the a2 in 2007 has generated a good deal of controversy we will refer to these countries collectively as the a10 henceforth 1 how many of these eastern europeans are there currently in the uk which countries did they come from and when what impact has their influx had on the uk economy and what likely impacts will they have in the future

the enlargement of the european union effects on trade and emissions of greenhouse gases abstract with the gradual accession of various central and eastern european countries ceecs to the european union eu international trade between the eu and the ceecs will change as a result of trade liberalisation and the mobility of production factors within the eu the eu and most of the ceecs have already committed themselves to reduce by 2008 2012 their emissions of greenhouse gases ghgs by 8 compared to the 1990 level this paper reports on an investigation of the potential consequences of the enlargement of the eu and of the emission reduction target set by the kyoto protocol on the sectoral production patterns and international trade a comparative static general equilibrium model was developed to examine the impacts under different scenarios for illustrative purposes two regions the eu and the ceecs and three categories of goods and services agricultural goods industrial goods and services were included the model was calibrated by the 1998 data the model was subsequently applied to study the effects of free trade the mobility of factors and the environmental constraints on production and international trade in light of the enlargement of the eu we show that in this specific context free trade is beneficial to economic welfare and does not necessarily increase emissions of greenhouse gases the mobility of factors also increases economic welfare but in the case of fixed production technology it may harm the environment through more emissions of ghgs

disentangling market access effects of preferential trading arrangements with an application for asean members under an asean eu fta the paper develops two synthetic measures at the hs 10 level to depict effective market access for a country receiving preferential access and applies these to the market access asean members would receive following the implementation of an fta with the eu first the measures show that current effective market access for asean eba members is cut in half by the preferences granted by the eu to countries that compete with these countries in the eu markets second the measures show that about one quarter of the preferential margin under the proposed fta for eba members would be lost as a result of preferential access granted to asean gsp members third disaggregated estimates of the restrictiveness of rules of origin confirm that rules are more restrictive for products with higher preferential margins and that asean countries usually face tougher rules of origin in the eu because of the composition of their exports

the impacts of exchange rate volatility on vegetable trade flows trade flows of commodities are generally affected by the principles of comparative advantage in a free trade however trade flows might be enhanced or distorted not only by various government interventions but also by exchange rate fluctuations among others this study applies a commodity specific gravity model to selected vegetable trade flows among organization for economic co operation and development oecd countries to determine the effects of exchange rate uncertainty on the trade flows using the data from 1996 to 2002 the results show that while the exchange rate uncertainty significantly reduces trade in the majority of commodity flows there is evidence that both short and long term volatility have positive effect on trade flows of specific commodities this study also tests the regional preferential trade agreements such as the north american free trade agreement nafta the asia pacific economic cooperation apec and the eu and their different effects on commodities

assessing the impact of unilateral trade policies eba and agoa on african beneficiaries exports using matching econometrics the existing literature studying the impact of non reciprocal preferential trade agreements nrptas assumes implicitly nrptas are non randomly assigned without showing the evidence of that using a matching methodology this paper investigates whether the african growth and opportunity act agoa and the everything but arms eba unilateral trade concessions have had an impact and in what magnitude on the exports of african beneficiary countries in the light of the evidence of the non random nature endogeneity of nrptas methodologically previous studies using the matching procedure focused on bi or multilateral trade agreements our work focuses on nrptas that depend only on donors conditions accordingly we show that for nrptas gravity covariates cannot be used for the matching procedure we propose to use political variables as determinants for obtaining non reciprocal trade preferences in order to address the endogenous nature of nrpta assignment our main results confirm that a country becomes eligible for a nrpta only when it meets certain conditions defined by their donors such as political stability and economic regulation for agoa and freedom of expression and human development for eba results also show that both agoa and eba policies have had a positive impact on african beneficiary countries exports to nrpta s providers even if the magnitude impact of eba is significantly lower than that of agoa

impacts of regulating greenhouse gas emissions on livestock trade flows policies regulating greenhouse gas ghg emissions are expected to create a significant burden on emitting industries as well as final consumers which can lead to a strong influence on international trade flows of commodities this study examines whether the regulation of ghg emissions affects livestock trade flows a commodity specific gravity model approach is employed to estimate and test the impact of regulating ghg emissions on livestock trade flows the results show that regulation of ghg emissions has a negative effect on livestock trade flows from countries restricting ghg emissions to countries without ghg restriction from restricting countries to restricting countries and unrestricting countries to restricting countries

revisiting the effects of regional trade agreements on trade flows with proper specification of the gravity model this paper uses a gravity model to assess ex post regional trade agreements the model includes 130 countries and is estimated with panel data over the period 1962 1996 the introduction of the correct number of dummy variables allows for identification of vinerian trade creation and trade diversion effects while the estimation method takes into account the unobservable characteristics of each pairs of trade partner countries the endogeneity of some of the explanatory variables as well as a potential selection bias in contrast to previous estimates results show that regional agreements have generated a significant increase in trade between members often at the expense of the rest of the world

changes in job instability and insecurity using monthly survey data this article provides evidence on changes in short term job instability and insecurity using the survey of income and program participation monthly measures from this data set are contrasted with annual measures from the survey of income and program participation and the panel study of income dynamics neither data set shows an increase in job turnover during the 1980s and 1990s we also examine indicators of increased insecurity these include the probability that a job ends involuntarily is followed by a spell of nonemployment or that the subsequent job has lower wages these indicators of insecurity also show no upward trend

do professionals choke under pressure high rewards or the threat of severe punishment provide strong motivation but also create psychological pressure which might induce performance decrements by analyzing the performance of professional football players in penalty kick situations the paper provides empirical evidence for the existence of detrimental incentive effects two pressure variables are considered in particular 1 the importance of success and 2 the presence of spectators there are plenty of situations in which pressure arises in the workplace knowing how individuals perform under pressure conditions is crucial because it has implications for the design of the workplace and the design of incentive schemes

mind the gap please the changing nature of entry jobs in britain we examine wages in jobs taken by those out of work entry jobs and the characteristics of the individuals who fill them there are large entry wage gaps relative to other jobs more importantly real entry wages have fallen by around 20 log points relative to all other jobs since 1979 one quarter of this decline is accounted for by differences in individual and job characteristics and around 40 from an unexplained fall in the position of entry jobs in the wage distribution that entry wages differ from the stock of all wages should be incorporated into labour supply modelling

professionals play minimax the implications of the minimax theorem are tested using natural data the tests use a unique data set from penalty kicks in professional soccer games in this natural setting experts play a one shot two person zero sum game the results of the tests are remarkably consistent with equilibrium play in every respect i winning probabilities are statistically identical across strategies for players ii players choices are serially independent the tests have substantial power to distinguish equilibrium play from disequilibrium alternatives these results represent the first time that both implications of von neumann s minimax theorem are supported under natural conditions during the last few decades game theory has contributed to a reshaping of important aspects of the methodology of economics and other social sciences in a large part this is because the language concepts and techniques of non cooperative game theory have become central to many areas of the discipline undoubtedly studying the interaction of ideally rational players greatly aids our understanding of the behaviour of real individuals firms and other agents moreover as kreps 1991 remarks studying the former should aim at understanding the latter the point of game theory is to help economists understand and predict what will happen in economic social and political contexts theoretical contributions should thus feed back to empirical analysis however testing the implications of the theory has proven extremely difficult in the literature the primary reason is that many predictions often hinge on properties of the utility functions and the values of the rewards used even when predictions are invariant over classes of preferences data on rewards are seldom available in natural settings moreover there is often great difficulty in determining strategy sets and in measuring individuals choices effort levels and the incentive structures they face as a result even the most fundamental predictions of game theoretical models have not yet been supported empirically in real situations in view of the substantial problems associated with testing theoretical predictions using natural data many authors have been compelled to test them in experimental settings interestingly enough despite the controlled structure of experiments the results of many experiments during the last few decades typically reject the assumption that subjects are playing according to the theoretical implications of equilibrium play for instance a number of experiments have evaluated the empirical validity of von neumann s minimax theory for two person zero sum games a theory that occupies a central position in our understanding of strategic situations the results have been mixed and are often rather negative see for instance brown and rosenthal 1990 rapoport and boebel 1992 camerer 2003 and the references therein

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

does environmental dumping lead to delocation environmental dumping is often viewed as an instrument used by some countries in the attempt to attract foreign investments stated otherwise the delocation of firms would be a major outcome of a stiff environmental policy in this paper we study the impact of a strict anti pollution policy pursued by a government on domestic firms locational decisions and determine the main variables that interact with such a policy some preliminary welfare implications are also provided

tightening environmental standards the benefit cost or the no cost paradigm ms ff ichael porter and claas van der linde have written a paper that is interesting and to us at least somewhat astonishing it is a defense of environmental regulation indeed an invitation to more stringent regulation that makes essentially no reference to the social benefits of such regulation this approach contrasts starkly with the methods that economists and other policy analysts have traditionally used when assessing environmental or other regulatory programs the traditional approach consists of comparing the beneficial effects of regulation with the costs that must be borne to secure these benefits for environmental regulation the social benefits include the reductions in morbidity or premature mortality that can accompany cleaner air the enhanced recreational opportunities that can result from water quality improvements the increased land values that might attend the cleanup of a hazardous waste site the enhanced vitality of aquatic ecosystems that might follow reductions in agricultural pesticide use or any of the other potentially significant benefits associated with tighter standards from this benefit cost approach emerges the standard tradeoff discussed in virtually every economics textbook porter and van der linde deny the validity of this approach to the analysis of environmental regulation claiming it to be an artifact of what they see as a static mindset in their view economists have failed to appreciate the capacity of

unilateral climate policy and competitiveness economic implications of differential emission pricing unilateral emission reduction commitments raise concerns on international competitiveness and emission leakage that result in preferential regulatory treatment of domestic energy intensive and trade exposed industries our analysis illustrates the potential pitfalls of climate policy design which narrowly focuses on competitiveness concerns about energy intensive and trade exposed eite branches the sector specific gains of preferential regulation in favour of these branches must be traded off against the additional burden imposed on other industries beyond burden shifting between industries differential emission pricing bears the risk for substantial excess cost in emission reduction as policy concedes too low carbon prices to eite industries and thereby foregoes relatively cheap abatement options in these sectors from the perspective of global cost effectiveness we find that differential emission pricing of eite industries hardly reduces emission leakage since the latter is driven through robust international energy market responses to emission constraints as a consequence the scope for efficiency compared to uniform pricing is very limited only towards stringent emission reduction targets will a moderate price differentiation achieve sufficient gains from leakage reduction to offset the losses of diverging marginal abatement cost

toward a new conception of the environment competitiveness relationship accepting a fixed trade off between environmental regulation and competitiveness unnecessarily raises costs and slows down environmental progress studies finding high environmental compliance costs have traditionally focused on static cost impacts ignoring any offsetting productivity benefits from innovation they typically overestimated compliance costs neglected innovation offsets and disregarded the affected industry s initial competitiveness rather than simply adding to cost properly crafted environmental standards can trigger innovation offsets allowing companies to improve their resource productivity shifting the debate from pollution control to pollution prevention was a step forward it is now necessary to make the next step and focus on resource productivity

does player specialization predict player actions evidence from penalty kicks at fifa world cup and uefa euro cup penalty kicks are analysed in the literature as real life experiments for assessing the use of rational mixed strategies by professional players however each penalty kick cannot be considered a repetition of the same event because of the varying background conditions in particular the heterogeneous ability of different players consequently aggregate statistics over data sets composed of a large number of penalty kicks mediate the behaviour of the players in different games and the properties of optimal mixed strategies cannot be tested directly because of aggregation bias in this article we model the heterogeneous ability of players we then test the hypothesis that differently talented players randomize over different actions to achieve this aim we study a data set that collects penalties kicked during shoot out series in the last editions of fifa world cup and uefa euro cup 1994 2012 where kickers are categorized as specialists and non specialists the results support our theoretical predi

unemployment in britain male unemployment in britain has risen from around 2 per cent in the 1950s to around 17 per cent in 1985 see figure 1 the figures are for male unemployment because there is no consistent series for women 1 even more remarkably unemployment has fallen in only three years out of the last twenty 1973 1978 and 1979 to account for this we need a model that explains both changes in the natural or non accelerating inflation rate of unemployment nairu and deviations from it we use a three equation supply side model centred on the labour market this has two main features the first concerns the determination of employment in the short run the labour demand function that we use cuts through the fruitless debate now raging especially in europe as to whether current unemployment is classical or keynesian according to the classical view employment is too high because real wages are too high according to the keynesian view real wages are not binding and unemployment is high because the product market does not clear with prices too high relative to nominal demand the whole debate is set in the framework of perfect competition yet in perfect competition prices are set by impersonal forces and it is not clear what could possibly stop prices clearing the market it is much more reasonable to think of prices as being set by imperfectly competitive firms existing prices being the best they can think of given the demand they face in this context firms demand for labour will depend on both the real product wage and the level of real aggregate demand this is the demand function we estimate and it conforms both to common sense and to the data however this does not imply that employment can be made to grow without limit by pumping up real demand for in the medium term when price surprises are eliminated our model determines three variables employment real wages and real demand on the basis of three equations an employment equation a price equation and a wage equation thus in the medium term there is a natural level of employment and corresponding to this a natural level of real aggregate demand the second key feature of our model concerns the medium term determination of unemployment in the medium term the planned mark up of wages over prices in wage settlements must be consistent with the mark up of prices over wage costs in employers pricing behaviour for if wage setters try to set real product wages higher than is consistent with employers pricing behaviour this generates ever increasing inflation thus the key to understanding unemployment in the medium term is the behaviour of wage setters if events occur that push them towards too high real wages then unemployment has to rise to offset these influences we shall call these influences wage pressure variables or push factors and they are clearly crucial in understanding unemployment the variables here include the social security system employment protection

job insecurity and wages this paper examines whether subjective expectations of unemployment are reliable indicators of the probability of becoming unemployed and investigates their association with wage growth we find that workers fears of unemployment are increased by their previous unemployment experience and by the unemployment experiences of a close friend and are associated with other objective indicators of insecure jobs we then show that unemployment fear predicts future unemployment above and beyond observed objective variables high fears of unemployment are found to be associated with significantly lower levels of wage growth for men but to have no significant link with wage growth for women

china s one belt one road initiative the impact of trade facilitation versus physical infrastructure on exports the one belt one road obor project is perhaps china s most significant international relations initiative in recent times it is based on openness harmony inclusivity mutual benefit and market operations and aims to connect the economically vibrant east asia and the developed europe by land and by sea and in the process it brings growth and development to tens of countries along the modern silk routes in this paper we compare the impact of the main initiatives of obor namely enhancements in physical infrastructure and improvements in border administration on the trade of countries that have signed on to this project especially countries along the six economic corridors we find overwhelming evidence that shows improvements in border administration has the greatest impact on exports of corridor countries although physical infrastructure is important for trade the chinese government should place equal attention to improvements in trade facilitation to ensure trade routes operate seamlessly across the various corridors

is job insecurity on the rise evidence from canadian perception data this paper examines the unexplored issue of worker insecurity perception in canada specifically we explore for changes in worker perceptions of job security using canadian gallup data for the 1977 2006 period we find that the high levels of perceived insecurity of the early to mid 1990s were only cyclical in nature not evidence of structural change we also explore for differences across socio economic groups and find that university educated workers full time workers and white collar workers all felt relatively more secure about present and future job prospects interestingly union members tend to be more concerned about job security than non union ce memoire examine le probleme inexplore de la perception de la precarite de l emploi au canada specifiquement on explore les changements dans les perceptions de precarite d emploi des travailleurs a l aide de donnees gallup pour la periode 1977 2006 il appert que les hauts niveaux de precarite percue du debut au milieu des annees 90 etaient de nature cyclique et non pas le resultat d un changement structurel on examine aussi les differences entre groupes socio economiques et on decouvre que les travailleurs avec une formation universitaire les travailleurs a temps plein et les collets blancs se sentaient relativement plus en securite quant aux perspectives d emploi presentes et futures il est interessant de noter que les travailleurs syndiques sont davantage inquiets quant a la precarite de l emploi que les non syndiques

public and private sector wages interactions in a general equilibrium model it is common wisdom that public sector wages are not determined in the same way as private sector wages at the same time the empirical evidence available for oecd countries finds a strong positive correlation between public and private sector wages in this paper we develop a model that is consistent with a political economy view of the determination of public sector wages and employment while being consistent with the said empirical evidence public finance constraints are crucial in booms governments expand employment and wages while in downturns lack of tax revenues forces the government to cut back the wage bill

the impact of environmental policy on international competitiveness in manufacturing the aim of this study is to test the hypothesis that environmental stringency adversely affects the international competitiveness net exports in manufacturing sectors the model follows the standard factor endowment approach to explain the effects of environmental regulatory policy on net exports in different product based industries an econometric model is constructed which includes factor endowments and environmental regulations to examine how strict environmental policies impact export competitiveness a panel dataset of 10 organisation for economic co operation and development oecd countries over 17 years 1987 2003 was constructed for the modelling effort the study finds that environmental regulations can be a way to combat the flight of manufacturing out of developed countries if the output from these industries can be identified as environmentally friendly a positive relationship between net exports and environmental regulations was found for paper products wood products and textile prod

the demand for english league football a club level analysis a demand equation is estimated for 19 large urban based english football league clubs over the period 1962 3 to 1991 2 in order to analyse the economic determinants of club attendances while controlling for football specific factors attendances are measured with and without correction for admission of season ticket holders using an error correction specification to model attendances it is shown that both adjusted and unadjusted attendances respond to real ticket prices in the long run in 17 and 18 clubs respectively the price elasticity is typically larger for adjusted attendances suggesting that casual spectators are more price sensitive than season ticket holders among football specific factors league position goals scored and promotion and relegation between the divisions are all important determinants of attendance patterns

gstp tariff reduction and its effects on south south trade in manufactures using a gravity model with import tariffs on manufactures as an explanatory variable both at the import and at the export side the impact of tariffs on trade in manufactures is analyzed for a sample of 39 less developed country ldc importers the consequences of an agreement on a global system of trade preferences gstp for manufactures are estimated by lowering these tariffs for intra ldc trade by 20 and 50 alternatively the short term effects are found to be relatively modest and the long term effects considerably larger trade diversion from developed country dc to ldc suppliers has only limited impact

aid for trade effectiveness complementarities with economic integration developing countries are increasingly using regional integration as a main policy lever when pursuing a trade led growth strategy and today deep preferential trade agreements go beyond trade policy negotiations and cover trade facilitation issues since aid for trade aft has been recognised as a powerful instrument for increasing developing countries trade capacity by targeting internal trade costs this article tests whether complementarities exist between this type of aid and economic integration using a gravity model on panel data for the period 1995 2005 results indicate that aft when combined with economic integration has been effective in increasing trade flows both south south and north south trade flows have benefited and the combination of the two instruments has been particularly effective in expanding the south s exports to the north finally when breaking down aft into categories assistance to trade related institutions seems to generate the strongest complementarities with economic integration

wages and product market power this paper analyses time series on some 800 british manufacturing companies to address various questions concerning the role of insiders and market power in wage determination the following are the most important results first product market power has a positive impact on wages this impact is enhanced in large firms but is not influenced by union status second while firm specific factors influence wages the size of these effects is not influenced by union status firm size or product market power however product market power reduces the generally strong negative effect of unemployment on wages finally there is no robust evidence of insider power at work in wage setting irrespective of product market position

economic integration among developed developing and centrally planned economies a comparative analysis we examine six integration schemes and decompose their ability to increase inter member trade into environmental policy and system effects environmental factors caused the greatest variation in trade creation with inter member distance the most important environmental variable the cacm and efta have followed more effective integration policies than the eec lafta and the andean pact although integration can thus benefit developed and developing countries alike for some such as those in latin america inter member distances severely limit its effectiveness while the combination of policy and system has kept the cmea fromrr achieving its full potential for increasing inter member trade its effectiveness does not differ from that of unions among market economies

long run trends in workers beliefs about their own job security evidence from the general social survey in recent years federal reserve chairman alan greenspan former u s secretary of labor robert reich and many journalists have argued that workers are more anxious about losing their jobs than they were in the past i use the 1977 96 general social survey to document trends in workers beliefs about their own job security during the 1990s workers have been more pessimistic about losing their jobs in the next 12 months than workers were during the 1980s workers have also been more concerned about suffering future job loss that would have resulted in a decline in earnings or a spell of unemployment

is india specialising in polluting industries evidence from us india bilateral trade recently the apex environmental agency of india observed that domestic industrial pollution has been increasing at an alarming rate over the last two decades and the need to rein in traditional polluting industries this raises the pertinent question of whether the poor domestic pollution regime has affected the pattern of india s trade in dirty manufactured products in the post liberalisation era since 1991 we find that on the whole india has remained a net importer of pollution intensive manufactured goods however there is a distinct trend of increasing specialisation in specific dirty industries especially in the bilateral trade with high income countries and to a lesser degree with low income countries the usa being india s single largest country trading partner in the post liberalisation era we test for pollution offshoring at the finer industry level in us india bilateral trade while we find that the pollution haven effect is not significant india s specialisation in certain dirty manufacturing industries through the last decade remains a disturbing trend india needs to integrate environmental sustainability within industrial growth urgently and it is pertinent to implement policies which would reflect the true pollution costs in an industry that is increasingly competing in the international market

trade creation and trade diversion in the eec the lafta and the cmea 1960 1994 in a simplified version of the gravity model appropriate dummy variables have been introduced to analyse the effects of both trade creation and trade diversion by three economic organizations the european economic community eec the latin american free trade association lafta and the council of mutual economic assistance cmea for the period 1960 94 five year intervals are the main subject of measurement the results show that both trade creation dummies and trade diversion dummies have statistically significant coefficients which show the appropriateness of this new approach the trade creation effect and trade diversion effect of each institution are proved to be generally weakening during the 1990s it is also observed that each organization has a distinctive international trade character for japanese trade a similar approach is used to analyse nonaligned trade by japan with particular interest in the effects of these three institutions on trade with japan the result is that there is no s

unionism and employment behaviour although there exists a large literature on the effects of trade unions upon wages there is no published work that uses microeconomic data on establishments to examine the employment consequences of unionism this paper addresses this issue with a recent british data set and shows that even after the addition of a substantial set of control variables there is a strong association between poor employment performance and the presence of trade unions the union employment growth differential is estimated at approximately 3 percent per annum copyright 1991 by royal economic society

do trade unions reduce job opportunities of non members this paper examines the structure of the optimal contract that would be chosen by a self interested trade union that represents the interests of some set of m members when it is assumed that there exists a pool of unemployed workers outside the union whose opportunity cost of working is such that they would at least in some states of demand have been employed in a competitive labor market the authors compare wage and employment levels under such a contract with those that would be observed in competitive markets in particular focusing on the impact of the union on the employment opportunities and welfare of non union members copyright 1989 by royal economic society

long run wage and earnings losses of displaced workers displacement related losses are estimated using national longitudinal survey of youth data that span the years 1979 2000 the typical displaced worker faces losses of 34 065 during the period 4 years prior through 5 years following displacement proportionally this represents a 10 8 loss compared to earnings of similar nondisplaced workers over the period considerable variation in losses is reported across worker types union male and more mature workers suffer greater losses respectively than do their nonunion female and younger counterparts college graduates and high school dropouts are found to suffer lower losses compared to high school diploma holders and those who completed some college

is environmental efficiency trade inducing or trade hindering abstract global efforts to identify strategies for sustainable economic growth and development underline the need for understanding important links between environmental policies and international trade in this paper by constructing an environmental efficiency index for 111 countries from 1980 to 2009 we are able to empirically test for one such link an improvement in the environmental efficiency index in terms of carbon dioxide emissions reflects a decrease in the cost of efforts to mitigate the environmental costs associated with growth countries that improve their environmental efficiency are found to experience strong international trade effects both through increased exports and increased imports while the positive link between efficiency improvements and exports is supportive of the porter hypothesis the positive link between efficiency improvements and imports is supportive of strong positive income effects on account of environmental efforts these results which are robust to alternative estimation strategies lend strong support to global efforts to improve countries environmental efficiencies

psychological pressure in competitive environments evidence from a randomized natural experiment much like cognitive abilities emotional skills can have major eects on performance and economic outcomes this paper studies the behavior of professional subjects involved in a dynamic competition in their own natural environment the setting is a penalty shoot out in soccer where two teams compete in a tournament framework taking turns in a sequence of ve penalty kicks each as the kicking order is determined by the random outcome of a coin ip the treatment and control

does mercosur s trade performance raise concerns about the effects of regional trade arrangements this study employs a new methodological approach that measures production efficiency in changing trade patterns it shows that the most rapidly growing products in mercosur s intratrade generally are goods in which members do not have a comparative advantage and have not been able to export competitively to outside markets this is consistent with substantial trade diversion within the arrangement mercosur s discriminatory tariffs against nonmembers which are four to six times higher than those in arrangements such as the european union european free trade area or north american free trade agreement are likely the cause recent further increases in mercosur s tariffs against nonmembers are likely to exacerbate the magnitude of trade diversion

a picture of job insecurity facing british men this paper considers three aspects of the job insecurity facing british men in the last two decades the probability of becoming unemployed the costs of unemployment in terms of real wages losses and the probability that the continuously employed will experience substantial real wage losses the first of these has not risen in the last two decades the second has risen by around 50 percent and the third has risen particularly for the top skill groups

unemployment and subsequent earnings estimating scarring among british men 1984 94 this paper estimates the impact of unemployment on earnings following re employment for a large and representative sample of british men 1984 94 unemployment incidence is found to have only a temporary effect an average earnings setback of 10 on initial re engagement largely eroding over two years the effect of unemployment duration by contrast is permanent a one year spell adding a further penalty of 10 percentage points these wage penalties are least for young men and the low paid those most at risk of unemployment and greatest for prime age and highly paid men

cleaning up while cleaning up pollution abatement interest groups and contingent trade policies this paper analyzes the political economy of environmental policy formation in a trading economy with established rules for administered protection we argue that the social costs associated with the adoption of an inefficient environmental regime are likely to be compounded by induced restrictions on trade when the effected industries are import competing the preferences of interest groups for alternative environmental regimes tend to be linked to the legal institutional setting in which trade policy is conducted under existing rules and practices in the area of administered protection there is reason to believe that interest group preferences for an inefficient approach to pollution control will be strengthened because the adoption of such a regime is more likely to lead to a concomitant increase in trade barriers

a gravity model analysis of meat trade policies abstract the conventional gravity model is revised for a single commodity and applied to meat markets to determine factors affecting trade flows of meat this study demonstrates that the gravity model for a single agricultural commodity can be parameterized more effectively by using time series and cross section data rather than cross section data alone this study reveals that trade policies and subsidies used by exporting and importing countries livestock production capacity in countries and distances play an important role in determining trade flows of meat long term agreements achieve the highest performance toward enhancing international meat trade import quotas and the hoof and mouth disease on beef greatly impair meat trade
