involuntary unemployment and implicit contracts this paper provides an explanation of involuntary umemployment arising as a consequence of asymmetric information between firms and workers involuntary unemployment is defined as a situation where ex post gains to trade exist a model of labor contracts is developed where the allocations are not ex post optimal it is shown that inferiority of leisure is a necessary and sufficient condition for the existence of involuntary unemployment

learning wage dynamics and firm specific human capital we introduce a dynamic and fully strategic model of wage determination in the presence of firm specific human capital in this model human capital is interpreted as information we show that equilibrium exists and is efficient and that it gives rise to a unique distribution of the social surplus we show further that the equilibrium wage is determined by three factors consideration of these factors allows us to determine when and how the market mechanism enables the worker to capture some of the returns to firm specific human capital we relate our findings to the ongoing empirical debate concerning the return to tenure

wage employment contracts this paper studies the efficient agreements about the dependence of workers earnings on employment when the employment level is controlled by firms the firms superior information about profitability conditions is responsible for this form of contract governance under plausible assumptions such agreements will cause employment to diverge from efficiency as a byproduct of their attempt to mitigate risk it is shown that if leisure is a normal good and firms are risk neutral employment is always above the efficient level such a one period implicit contracting model cannot therefore be used to explain unemployment as a rational byproduct of risk sharing between workers and a risk neutral firm under conditions of asymmetric information

an alternative approach to estimate the wage returns to private sector training summary this paper follows an alternative approach to identify the wage effects of private sector training the idea is to narrow down the comparison group by only taking into consideration the workers who wanted to participate in training but did not do so because of some random event this makes the comparison group increasingly similar to the group of participants in terms of observed individual characteristics and the characteristics of planned training events at the same time the point estimate of the average return to training consistently drops from a large and significant return to a point estimate close to zero copyright 2008 john wiley sons ltd

the economics of a blend mandate for biofuels a biofuel blend mandate may increase or decrease consumer fuel prices with endogenous oil prices depending on relative supply elasticities biofuel tax credits always reduce fuel prices tax credits result in lower fuel prices than under a mandate for the same level of biofuel production if tax credits are implemented alongside mandates then tax credits subsidize fuel consumption instead of biofuels this contradicts energy policy goals by increasing oil dependency co 2 emissions and traffic congestion while providing little benefit to either corn or ethanol producers these social costs will be substantial with tax credits costing taxpayers 28 7 billion annually by 2022 copyright 2008 oxford university press

stacking low carbon policies on the renewable fuels standard economic and greenhouse gas implications this paper examines the economic and ghg implications of stacking a low carbon fuel standard lcfs with and without a carbon price policy on the renewable fuel standard rfs we compare the performance of various policy combinations for food and fuel prices fuel mix and fuel consumption we also analyze the economic costs and benefits of alternative policy combinations and their distributional effects for consumers and producers in the transportation and agricultural sector in the us using a dynamic multi market partial equilibrium model of the transportation and agricultural sectors we find that combining the rfs with an lcfs policy leads to a reduction in first generation biofuels and an increase in second generation biofuels compared to the rfs alone this policy combination also achieves greater reduction in ghg emissions even after considering offsetting market mediated effects imposition of a carbon price with the rfs and lcfs policy primarily induces fuel conservation and achieves larger ghg emissions reduction compared to the other policy scenarios all these policy combinations lead to higher net economic benefits for the transportation and agricultural sectors relative to the no policy baseline because they improve the terms of trade for us

general training in labor markets common value auctions with unobservable investment abstract this paper studies the puzzle of employer financing for the general training of workers a parsimonious theory is developed based on asymmetric information between employers about the quantity of training the labor market is modeled as a common value auction with an informed and an uninformed bidder the novel feature of the game is that one of the bidders can make an unobservable investment that increases the value of the item before the auction by randomizing the amount of training provided an employer can create an endogenous adverse selection problem enabling it to compress the wage structure and capture some returns from its training investment the model generates continuous equilibrium wage and training distributions and identical employees can receive different wage offers and training levels a parametric example is used to illustrate how the shape of the wage distribution depends on the elasticity of production with respect to human capital

an institutional critique of intergovernmentalism most intergovernmentalist analyses of european integration focus on treaty bargaining among european union member governments recent articles also have examined everyday decision making through power index analysis an approach that asserts that a government s ability to influence policy is a function of all possible coalitions in the council of ministers to which it is pivotal this approach suffers from two major weaknesses first it fails to take into account the policy preferences of governments it overestimates the influence of governments holding extreme preferences and underestimates that of more centrist governments second power index analysis fails to consider the important roles of the commission of the european communities and the european parliament in legislative processes today s procedures affect the mix of agenda setting and veto power and this has systematic effects on policy outcomes if intergovernmentalism is to explain choices made during treaty rounds it must take into account these legislative dynamics

education training and employability two hypotheses are tested 1 education and training increase the employability of workers at other tasks within the firm and reduce the need for help from supervisors when workers encounter small problems and 2 greater employability and problem solving capability increase wages the empirical results show that greater employability and problem solving capability are independent from each other formal work related training increases employability workers in jobs requiring no induction training are less employable at other jobs or departments both general and specific human capital increase the ability of workers to solve problems on their own greater employability does not increase wages male workers who solve problems on their own earn more than men who need help from others the effects of human capital variables on employability and problem solving capability do not differ between and men and women however it is found that the ability to solve problems on one s own has a pay off for men but

an examination of firms employment costs the existence of quasi fixed costs of work may affect firms desired employee hours and number of workers which has important implications for the estimation of labour supply parameters firm level data from the 1982 employment opportunity pilot project is used to estimate the importance to firms of employee quasi fixed costs related to searching hiring training and firing specifically this paper examines how these costs affect number of workers and hours per worker turnover and vacancies to the extent that the costs are determined by the firm s presumably exogenous industrial classification an attempt is made to control for biases due to employee heterogeneity as well results show that higher costs are associated with lower turnover fewer vacancies and longer hours as predicted by a model of labour demand

welfare impacts of alternative biofuel and energy policies an open economy equilibrium model is derived to investigate the effects of energy policy on the u s economy with emphasis on corn based ethanol a second best policy of a fuel tax and ethanol subsidy is found to approximate fairly closely the welfare gains associated with the first best policy of an optimal carbon tax and tariffs on traded goods the largest economic gains to the u s economy from these energy policies arise from their impact on u s terms of trade particularly in the oil market conditional on the current fuel tax an optimal ethanol mandate is superior to an optimal ethanol subsidy copyright 2011 oxford university press

union egalitarianism as income insurance it is a common observation that unions often try to compress the wage distribution among their members as compared with the productivity distribution a troublesome aspect of standard theories of redistributive unions is the question why high productivity workers choose to enter the union in the first place this paper develops and explores the implications of an alternative insurance rationale for egalitarian wage objectives apart from providing a simple explanation of why heterogeneous union members may agree on egalitarian wage policies it also suggests a more guarded attitude toward the welfare costs of pay compression copyright 1992 by the london school of economics and political science

intra firm wage compression and coverage of training costs evidence from linked employer employee data the author uses german linked employer employee data to estimate the impact of intra firm wage dispersion on the probability that establishments pay for further training about half of all establishments in the estimation sample cover all direct and indirect training costs which contradicts the standard human capital approach with perfect labor markets the main finding of cross section panel and instrumental variable probit estimations is that establishments with larger intra firm wage compression are more likely to cover all direct and indirect training costs which is consistent with theoretical considerations of the new training literature about imperfect labor markets

does demand for product quality increase worker training abstract we uniquely examine the relationship between firm organized training and the sensitivity of consumer demand to product quality cross section panel fixed effect and instrumental variable estimates confirm that british workplaces provide more intensive training when their product demand is more sensitive to product quality robustness checks including using alternative key variable definitions and a counterfactual analysis examining the importance of competing on price support this confirmation

enlargement processes and distributional conflicts the politics of discriminatory membership in the european union this paper examines discriminatory membership in the european union from a game theoretical perspective i argue that discriminatory membership enables the enlargement of international organizations with heterogenous member states eu members impose discriminatory measures on new members to redistribute enlargement gains from new members to particularly negatively affected eu members as to render expansion pareto efficient the empirical findings of a probit analysis on the eu accession negotiations and outcomes of all five eu enlargement rounds support the theoretical claim the eu grants acceding states restricted membership rights if distributional conflicts emerge moreover the candidate s bargaining power and the possibility of alternative compensation schemes influence the enlargement outcomes

the theory of human capital revisited on the interaction of general and specific investments human capital theory distinguishes between training in general usage and firm specific skills becker 1964 argues that employers will only invest in specific training not general training when labour markets are competitive the article reconsiders becker s theory using essentially his framework we show that there exists an incentive complementarity between employer sponsored general and specific training the possibility to provide specific training leads the employer to invest in general human capital conversely the latter reduces the hold up problem that arises with firm specific training we also consider the desirability of institutionalised training programmes and the virtues of breach penalties and discuss some empirical facts that could be explained by the theory

the community trap liberal norms rhetorical action and the eastern enlargement of the european union discipline 3 i begin my search for an explanation with liberal intergovernmentalism the most prominent and promising rationalist account of the major turning points in the history of european integration this perspective accounts plausibly for most of the enlargement preferences of the member states and explains why the association of central and eastern european countries to the european community ec was the initial outcome of the bargaining process among them it fails however to account for the community s decision to go beyond association and offer these countries full membership this puzzle is solved through a sociological perspective in which enlargement is understood as the expansion of international community if the eu is conceived of

carbon climate and economic breakeven times for biofuel from woody biomass from managed forests woody biomass harvested from old growth forests results in a significant carbon debt when used as a feedstock for transportation fuel this is because previously stored forest carbon is released to the atmosphere as co2 the debt is eventually repaid provided that the life cycle co2 emissions of the biofuel are lower than the conventional fuel that is displaced managed forests are an alternative to old growth forests with the potential to reduce the carbon debt associated with woody biomass derived fuels this work is the first to quantify the carbon debt incurred by transportation biofuels derived from woody biomass from managed forests the breakeven time of this carbon debt is computed along with breakeven times for radiative forcing temperature change and economic damages in the case of biofuel production for 30 years we find that breakeven times for carbon radiative forcing and temperature change are 59 42 and 48 years respectively if cumulative economic damages are computed for discount rates of 1 2 the breakeven time is greater than 100 years while damages never break even at discount rates above 2 breakeven times decrease if the prevailing harvest cycle is left unchanged but increase if biofuel production is sustained indefinitely

multiskilling technical change and the japanese firm worker cooperation with technical change accounts for much of the success of large japanese firms the authors argue t hat this cooperative attitude is due in large part to multiskilling by training workers in more than one job a firm assures its workers th at they will not be made worse off by labor saving innovations in a simple model the authors show that multiskilling leads to an endoge nous distinction between permanent and temporary workers wages that are attached to the worker rather than the job and comparative advantage in process style innovations there is even a role for the company song copyright 1993 by royal economic society

when competitive advantage doesn t lead to performance the resource based view and stakeholder bargaining power what if rent from a competitive advantage is appropriated so it cannot be observed in performance measures the resourcebased view was not formulated to examine who will get the rent yet this essay argues that the factors leading to a resource based advantage also predict who will appropriate rent knowledge based assets are promising because firm specificity social complexity and causal ambiguity make them hard to imit ate however the roles of internal stakeholders may grant them a great deal of bargaining power especially relative to investors this essay integrates the resource based view with the bargaining power literature by defining the firm as a nexus of contracts this new lens can help to explain when rent will be generated and simultaneously who will appropriate it in doing so it provides a more robust theory of firm performance than the resource based view alone it is also suggested that this lens might be useful for examining other theories of firm performance

supply of cellulosic biofuel feedstocks and regional production pattern interest in cellulosic biofuels has grown due to recent concerns about the impact of expanding production of corn ethanol on food prices and the greater potential of cellulosic biofuels to mitigate climate change the energy independence and security act eisa of 2007 limits the production of corn ethanol to 56 billion liters after 2015 and mandates the production of at least 80 of the 136 billion liters of ethanol from non corn starch based cellulosic feedstocks by 2022 the biomass research and development act of 2000 had established an even more ambitious goal of using biomass to replace the equivalent of 30 of current petroleum consumption by 2030 and estimated that this would require 1 billion dry short tons of biomass annually u s department of energy usdoe 2003 biomass can be obtained from several different sources including forest resources crop residues woody biomass and perennial grasses a usda usdoe report perlack et al 2005 examined the technical feasibility of sustaining this supply of biomass and the land resources that would be required under alternative scenarios with yield enhancing and other technological changes in conventional crops and perennial bioenergy crops the study estimated that 0 54 to 1 billion dry tons of agricultural crop based biomass could be obtained annually from cropland idle cropland and cropland pasture with moderate to high productivity gains in crop productivity residue collection and tillage practices

the wage effects of training in portugal differences across skill groups genders sectors and training types this article investigates the determinants and wage effects of training in portugal in a first stage we show that there are considerable differences in training participation across groups of workers with elder and low educated individuals participating substantially less in a second stage we show that training has a positive and significant impact on wages the estimated wage return is about 30 for men and 38 for women discriminating between levels of education and working experience and the public and private sector reveals important differences across categories of workers we find that women low educated workers and workers with long working experience earn larger returns from training the average effect of training is similar in the private sector and the public sector however differences across experience groups are larger in the private sector while differences across education groups are larger in the public sector we use three alternative classifications of training activities and f

international actors on the domestic scene membership conditionality and socialization by international institutions international relations scholars increasingly debate when and how international institutions influence domestic policy this examination of ethnic politics in four baltic and east european countries during the 1990s shows how european institutions shaped domestic policy and why these institutions sometimes failed comparing traditional rational choice mechanisms such as membership conditionality with more socialization based efforts i argue that conditionality motivated most behavior changes but that socialization based efforts often guided them furthermore using new case studies statistics and counterfactual analysis i find that domestic opposition posed far greater obstacles to socialization based methods than it did to conditionality when used alone socialization based methods rarely changed behavior when they did the domestic opposition was usually low and the effect was only moderate in contrast incentive based methods such as membership conditionality were crucial in changing policy as domestic opposition grew membership conditionality was not only increasingly necessary to change behavior but it was also surprisingly effective many panel and seminar participants have offered useful comments on this work but my thanks goes in particular to michael zurn alexandra gheciu frank schimmelfennig jeff checkel robert keohane steven wilkinson robert putnam milada vachudova and the editors and anonymous reviewers of international organization i also thank princeton university press for allowing me to use material from my book ethnic politics in europe the power of norms and incentives the usual caveats apply this research was funded by a grant from the danish research academy former forskerakademiet and by travel support from the weatherhead center for international affairs at harvard

second best biofuel policies and the welfare effects of quantity mandates and subsidies abstract the quest for biorenewable energy sources is held to justify a number of government interventions including support policies for biofuels such as those responsible for the recent rapid growth of us ethanol production this article provides an analytical assessment of such policies we construct a general equilibrium open economy model that captures the rationale typically invoked to justify government intervention in this setting to alleviate the environmental impact of energy consumption and to decrease us energy dependence on foreign sources the model is used to study both the positive and normative implications of alternative policy instruments including the subsidies and mandates specified by the 2007 energy independence and security act from a positive perspective we find that biofuels mandates are equivalent to a combination of fuel taxes and biofuels subsidies that are revenue neutral from a welfare perspective we show that biofuels mandates dominate biofuels subsidies and that combining fuel taxes with mandates would be welfare enhancing

specific investment and wage profiles in labour markets wage contracts like all civil contracts can be renegotiated by mutual consent this is not just a theoretical possibility but one that happens all the time annual wage increases for example are typically the result of genuine renegotiation not the result of formal cost of living escalator clauses this has implications for the effect of wage contracts on specitic investment the possibility of renegotiation reverses a number of the widely accepted arguments about the form wage contracts should take some of the results we show here are

training and worker effort a signalling perspective this paper analyzes the interaction between firms investment in general skills training and workers incentives it shows that when a firm has an informational advantage over its workers its provision of free general skills training can serve as a signal that there will be a long term relationship between the firm and its workers this signal induces the workers to exert more effort in learning firm specific skills which enhances the firm s profits in contrast with most of the existing literature the model implies that firms may provide free general skills training even if there is no labour market friction ce memoire analyse l interaction entre l investissement des entreprises dans l acquisition d habiletes generales de leurs employes et les incitations des travailleurs a fournir un effort on montre que quand une firme a un avantage informationnel sur ses travailleurs le fait de fournir gratuitement de la formation qui permette aux employes d acquerir des habiletes generales peut servir de signal qu il va y avoir une relation a long terme entre la firme et ses travailleurs ce signal incite les travailleurs a investir plus d effort dans l acquisition d habiletes specifiques a la firme ce qui augmente les profits de l entreprise ce modele en porte a faux par rapport au gros de la litterature existante suggere que les entreprises peuvent fournir gratuitement de la formation permettant aux employes d acquerir des habiletes generales meme s il n y a pas de friction dans le marche du travail

why do firms train theory and evidence this paper offers a theory of training whereby workers do not pay for the general training they receive the superior information of the current employer regarding its employees abilities relative to other firms creates ex post monopsony power and encourages this employer to provide and pay for training even if these skills are general the model can lead to multiple equlibria in one equilibrium quits are endogenously high and as a result employers have limited monopsony power and provide little training while in another equilibrium quits are low and training is high using microdata on german apprentices we show that the predictions of our model receive some support from the data

human capital and unemployment dynamics why more educated workers enjoy greater employment stability why do more educated workers experience lower unemployment rates and lower employment volatility empirically these workers have similar job finding rates but much lower and less volatile separation rates than their less educated peers we argue that on the job training being complementary to formal education is the reason for this pattern using a search and matching model with endogenous separations we show that investments in match specific human capital reduce incentives to separate but leave the job finding rate essentially unaffected the model generates unemployment dynamics quantitatively consistent with the data finally we provide novel empirical evidence supporting the mechanism studied in the paper this article is protected by copyright all rights reserved

the role of promotion in inducing specific human capital acquisition workers routinely carry out activities that increase their productivity with their current employer for which they are not directly compensated for example a worker may be asked to develop relationships with clients or shop floor staff or he may develop a better understanding of how his firm operates firmspecific human capital of this type is difficult to quantify so that it is likely to be difficult to directly compensate the worker for its acquisition this paper is concerned with designing compensation schemes for employees to induce them to collect nonverifiable firm specific human capital if firms develop reputations for fairly compensating workers for skill collection the vagueness of these skills may not provide a significant incentive problem i consider the case where firms do not have the opportunity to develop reputations as a result the acquisition of human capital is subject to a dual moral hazard problem first noted in kahn and huberman 1988 first a worker only collects skills if there is a promise of a higher wage if he does so second the employer has an incentive to claim that the worker has not collected these skills even when he in fact has in order to save on wage costs so on the one hand it is difficult to repay the worker after skills are collected as the firm has an incentive to renege however the worker cannot be repaid before collecting skills as he has no subsequent incentive to collect them following the institutional literature i assume that the firm can commit to a labor contract which attaches wages to different tasks the principal purpose of the paper is to show that the firm can use this ability to commit to a wage scale for different tasks to induce a worker to collect firm specific human capital in the presence of this dual moral hazard problem where the worker is rewarded for skill acquisition by promotion to another job assume that a worker can be assigned to one of two jobs d and

investment in general training the role of information and labour mobility following the seminal work of becker i964 it is widely accepted in the literature that firms will be unwilling to finance training which workers may use in other firms this paper takes issue with this prediction and suggests that firms will frequently share in the cost of such general training 1 becker argues that a firm which pays for the training of workers in skills of potential use to other firms will lose these workers since other firms bear none of the costs of general training they can attract a worker with such training by outbidding the firm which trained him recognising this absence of property rights over an investment in general training firms will refuse to provide it hence if general training is to take place the trainee will have to pay for it if potential trainees are unwilling or unable to pay general training will not take place a shortage in general training is likely to emerge this may be especially pronounced in developing countries 2 in contrast the outlook for

the politics of common knowledge ideas and institutional change in wage bargaining domestic economic institutions change through processes of conflict and bargaining why do the strongest groups in such conflicts ever change their minds about the acceptability of institutional arrangements they once opposed drawing on the cases of ireland in 1986 87 and italy in 1989 93 this article demonstrates how the process of common knowledge creation between employers and unions changed the course of negotiations over national wage bargaining institutions common knowledge creation happens when existing institutions are in crisis the institutional experimentation that follows such crises characterized by deep uncertainty places a premium on persuasive argument the ideas most likely to serve as the basis for newly common knowledge will have analytical and distributive appeal to both unions and employers and they must be ratified in public agreements which i call common knowledge events common knowledge events establish new social facts which can change the payoffs associated with different institutional outcomes this can lead even powerful actors to accept institutions they had previously opposed the author thanks marius busemeyer mary louise culpepper keith darden orfeo fioretos archon fung peter hall andrew martin cathie jo martin victoria murillo kathleen thelen and gunnar trumbull along with three anonymous reviewers and the editors of io for comments and conversations that improved this article ben ansell and vikram siddarth provided valuable research assistance financial support from the john f kennedy school of government and the weatherhead center for international affairs at harvard university is gratefully acknowledged any remaining errors are my own

constructing the international foundations of e commerce the eu u s safe harbor arrangement much recent international relations scholarship has argued that states are unable to control e commerce so that private actors are coming to play a dominant role however this body of literature fails to account for emerging hybrid institutions in which states create general frameworks of rules which are then implemented by private actors this article examines a prominent example of such an institution the eu u s safe harbor arrangement in the field of privacy and sets out an alternative explanation of state private actor relations in the sphere of e commerce it shows how safe harbor had its origins in efforts by the european union eu and united states to mitigate problems of interdependence that threatened to undermine the principles of order on which their regulatory systems were based safe harbor reflects neither the eu nor u s approach but rather a novel blend of state and private regulation the article demonstrates the vital role of argument and persuasion in identifying safe harbor as a solution and in negotiating its particulars it finds that conventional game theoretic accounts of bargaining are unable to explain the negotiation of safe harbor and argues that constructivist approaches should pay more attention to how argument can disclose new possibilities of action

general and specific training evidence and implications using data from the employer opportunity pilot project eopp survey and the national longitudinal survey of youth nlsy we explicitly document the specificity and generality of employer provided training and we analyze how wage growth and mobility are influenced by our direct measures of specific and general training in spite of the emphasis that labor economists have placed on specific training we find that employers in the eopp and workers in the nlsy indicate that most of the skills learned in training are useful elsewhere our results are consistent with several recent models that predict that employers will often extract some of the returns to the general training they provide

general human capital as a shared investment under asymmetric information the paper examines the firm s optimal wage and layoff policies in situations where only general training is provided and the firm providing training has an advantage in information over other firms the asymmetric information among firms creates adverse selection which seriously impairs the mobility of labour and consequently affects the firn s optimal policies general human capital is shown to have the same layoff and cost sharing implications as firm specific human capital furthermore the contracts prespecifying rigid wages are proven to be optimal le capital humain general en tant qu investissement conjoint quand l information est asyme trique ce m6moire examine les politiques optimales de salaires et de mises a pied d une firme quand seulement une formation generale est foumie et quand la firme qui donne la formation a un avantage informationnel sur les autres firmes l information asym6trique entre firmnes cree une selection adverse qui reduit serieusement la mobilite des travailleurs et en consequence affecte les politiques optimales de la firmne le capital humain a vocation generale a les meme implications que le capital humain a vocation specifique pour ce qui est des mises a pied et du partage des coufts de plus les contrats qui prespecifient des salaires rigides s averent optimaux

a dispositional theory of reputation costs politicians frequently turn to reputational arguments to bolster support for their proposed foreign policies yet despite the prevailing belief that domestic audiences care about reputation there is very little direct evidence that publics care about reputation costs and very little understanding of how we propose a dispositional theory of reputation costs in which citizens facing ill defined strategic situations turn to their core predispositions about foreign affairs in order to weigh competing reputational dimensions employing a diverse array of methodological tools from vignette based survey experiments to automated text analysis we show that the mass public has a taste for reputation but understands it in fundamentally different ways with hawks concerned about the negative reputational consequences of inconsistency and doves equally concerned with the negative reputational consequences of belligerence and interventionism in illustrating how reputation costs are in our heads our findings offer both good and bad news for theories of reputation in ir

substitution between biofuels and fossil fuels is there a green paradox we show that i subsidies for renewable energy policies with the intention of encouraging substitution away from fossil fuels may accentuate climate change damages by hastening fossil fuel extraction and that ii the opposite result holds under some specified conditions we focus on the case of subsidies for renewable resources produced under increasing marginal costs and assume that both the renewable resources and the fossil fuels are currently in use such subsidies have a direct effect and an indirect effect working in opposite directions the direct effect is the reduction in demand for fossil fuels at any given price the indirect effect is the reduction in the current equilibrium price for fossil fuels which tends to increase the amount of fossil fuels demanded whether the sum of the two effects will actually result in an earlier or later date of exhaustion of the stock of fossil fuels depends on the curvature of the demand curve for energy and of the supply curve for the renewable substitute

why do temporary help firms provide free general skills training the majority of u s temporary help supply ths firms offer nominally free unrestricted computer skills training a practice inconsistent with the competitive model of training i propose and test a model in which firms offer general training to induce self selection and perform screening of worker ability the model implies and the data confirm that firms providing training attract higher ability workers yet pay them lower wages after training thus beyond providing spot market labor ths firms sell information about worker quality to their clients the rapid growth of ths employment suggests that demand for worker screening is rising

the impact of product market competition on training provision evidence from canada while standard models of training focus on how input market affects firms training decisions this paper investigates the impact of product market competition on training provision using the longitudinal data from statistics canada s workplace and employee survey we find that increased competition is strongly associated with more training provision this association is unlikely to be driven by unobserved heterogeneity specific measures used and other relevant factors to the extent that training is a significant source of human capital and industry competitiveness our results suggest that increasing training is an important channel through which competition raises productivity

the impact of biofuels on commodity food prices assessment of findings for years agriculture has provided most of the fuel for vehicular transportation concerns about availability of fuels balance of trade and climate change led to the introduction of biofuel programs in the united states brazil europeanunion eu andothercountries the impacts of these programs and the relationship between the food and fuel markets have become major topics of economic research this paper summarizes the main findings of alternative lines of research on the relationship between the food and fuel markets and identifies gaps and quandaries that warrant further research this is not meant to be a complete survey and it emphasizes several of our studies within the broader literature the paper distinguishes between two bodies of literature one on the relationship between food and fuel prices and another on the impact of the introduction of biofuel on commodity food prices while biofuel prices do not seem to affect food commodity prices we explain why the introduction of biofuel does moreover biofuelshavenotbeenthemostdominant contributor to the recent food price inflation and different biofuels have different impacts

certification of training and training outcomes abstract external certification of workplace skills obtained through on the job training is widespread in many countries this may indicate that training is financed by workers and certification serves to assure the quality of the training offered by the firm however other evidence shows that general training is financed by firms especially in germany we show in this paper that external certification of training may also be necessary for an equilibrium with firm sponsored training firm financing of training is only possible if firms have monopsony power over the workers after training if the training firm can extract too much of the employment rents however workers may not have sufficient incentives to put forth effort during training certification increases the value training to the outside market and hence to workers making firm sponsored training possible

technical change and the returns and investments in firm level training evidence from thailand abstract this paper examines determinants of investments in and returns to training with focus on technical changes using employee panel data in thai manufacturing industries empirical findings demonstrate significant returns to both on the job and off the job training in first difference fixed effect estimation of wage equations controlling for technical changes which differentially influence training investments and the returns first returns to informal on the job training are robust contrary to findings from developed countries second technical change induces both on the job and off the job training and controlling for technical change makes returns to on the job training even larger implications for training and education policies are discussed

assessing the impact of us ethanol on fossil fuel markets a structural var approach abstract despite the growing importance of biofuels the effect of biofuels on fossil fuel markets is not fully understood we develop a joint structural vector auto regression var model of the global crude oil us gasoline and us ethanol markets to examine whether the us ethanol market has had any impact on global oil markets the structural var approach provides a unique method for decomposing price and quantity data into demand and supply shocks allowing us to estimate the distinct dynamic effects of ethanol demand and supply shocks on the real prices of crude oil and us gasoline ethanol demand in the us is driven mainly by government support in the form of tax credits and blending mandates shocks to ethanol demand therefore reflect changes in policy more than any other factor in contrast ethanol supply shocks are driven by changes in feedstock prices a principle finding is that a policy driven ethanol demand expansion causes a statistically significant decline in real crude oil prices while an ethanol supply expansion does not have a statistically significant impact on real oil prices this suggests that even though us ethanol market is small the influence of us biofuels policy on the crude oil market is pervasive we also show that ethanol demand shocks are more important than ethanol supply shocks in explaining the fluctuation of real prices of crude oil and us gasoline

intrafirm information management and wage dynamics abstract firms continually have to decide what information to transfer to what workers better informed workers produce more but they also demand higher wages reflecting improved outside options generally the firm is shown to gradually transfer information to its workers over their employment lives correspondingly the model can explain an upward sloping wage schedule or a return to tenure this paper specifically examines how the strategic information transfer by the firm to its workers over their work lives reflects i the rate of depreciation of the information after a quit if any ii its risk of obsolescence and iii asymmetric information on the part of the worker regarding his outside options asymmetric information regarding outside options can explain that some workers leave the firm in mid career

the structure and dynamics of eu federalism this article analyzes european union eu politics through the lens of comparative federalism the article assesses the contributions that rationalist and constructivist approaches can make to the analysis of eu federalism focusing on two broad questions first what explains shifts in authority from the state i e member states to the federal i e eu level second what explains the degree to which the federal government constrains state discretion this article develops testable hypotheses based on the rationalist and constructivist perspectives and presents a set of initial plausibility probes the article shows that there is considerable room for dialogue between rationalist and constructivist perspectives and together they can provide a more comprehensive explanation for the dynamics of eu federalism

the importance of lifetime jobs in the u s economy though the u s labor market is justly notorious for high turnover and consequent high unemployment it also provides stable near lifetime employment to an important fraction of the labor force this paper investigates patterns of job duration by age race and sex with the following major conclusions 1 the typical worker today is holding a job which has lasted or will last about eight years over a quarter of all workers are holding jobs which will last twenty years or more sixty percent hold jobs which will last five years or more 2 the jobs held by middle aged workers with more than ten years of tenure are extremely stable over the span of a decade only twenty to thirty percent come to an end 3 among workers aged thirty and above about forty percent are currently working in jobs which eventually will last twenty years or more three quarters are in jobs which will last five years or more 4 the duration of employment among blacks is just as long as among whites even though the jobs held by blacks are worse in almost every other dimension they are no more unstable than those held by whites 5 women s jobs are substantially shorter than men s on the average only about a quarter of all women over the age of thirty are employed in jobs which will last over twenty years whereas over half of men over thirty are holding these near lifetime jobs this abstract was borrowed from another version of this item

testing some predictions of human capital theory new training evidence from britain we confront the predictions of various theories with new training data from the british household panel survey we find that employer financed training is associated with significantly higher wages at current and future firms with a larger impact in future firms this is consistent with human capital theory with credit constraints and with the new training literature assuming imperfectly competitive labor markets

you paid for the skills now keep them tuition reimbursement and voluntary turnover does investing in employees marketable skills reduce turnover this study uses insights from human capital theory to explain how general skill development and promotion relate to voluntary turnover data from 9 439 salaried employees of a large manufacturer show that participation in tuition reimbursement reduces turnover while employees are in school voluntary turnover increases when individuals earn graduate degrees but is significantly reduced if they are subsequently promoted

enriching a theory of wage and promotion dynamics inside firms in previous work we showed that a model that integrates job assignment human capital acquisition and learning can explain several empirical findings concerning wage and promotion dynamics inside firms in this article we extend that model in two ways first we incorporate schooling and derive further testable implications that we then compare with the available empirical evidence second and more important we show that introducing task specific human capital allows us to produce cohort effects we further argue that task specific human capital is a realistic concept and may have many important implications we also discuss limitations of our extended approach

food vs fuel the effect of biofuel policies the rise in food commodity prices since 2004 which reached record highs in 2008 has coincided with the tripling of corn ethanol production from 15 billion liters bl to 50 bl over the 2004 2010 period this has spurred the food vs fuel debate and raised questions about the extent to which biofuels have contributed to the increase in food crop prices estimates of the impact of observed levels of biofuel production differ widely across studies and lie between 20 and 60 hochman et al 2011 biofuel production in the united states us has surged as a result of government policies like the renewable fuel standard rfs volumetric ethanol excise tax credit veetc for blenders of ethanol and tariffs that restrict the imports of sugarcane ethanol the rfs authorized by the energy independence and security act eisa of 2007 has set ambitious targets of increasing biofuel production sixfold to 136 bl by 2022 with over 60 of it to be met by advanced biofuels produced using non corn starch based feedstocks a 0 12 liter veetc is provided to blenders of ethanol to reduce their costs of meeting the rfs while a tariff of 0 14 liter and an ad valorem tariff of 2 5 were enacted to prevent transfer of the tax credit to ethanol producers in brazil the current veetc and import tariff expired in 2011 with increasing federal debt and concerns about the impact of these policies on food and feed prices political support for the

the role of off the job vs on the job training for the mobility of women workers the transition from school to work is typically a period in which many young workers experience a wide range of different jobs and experience some of their most rapid wage growth over their working life robert hall 1982 has estimated that the first 10 years of an individual s working career will include approximately two thirds of all lifetime job changes robert topel and michael ward 1988 found that over half of young male new entrants held six or more jobs over the first 10 years of their work experience only one young male worker in twenty held a single job for 10 years in their sample all of this suggests that young workers early years in the labor market involve several employment transitions the purpose of this paper is to examine for young workers in their first years of work the determinants of leaving an employer in particular this paper focuses on the role of different types of training on the probability of leaving an employer in previous work 1990 i have examined the impact of private sector training on the determination of wages and wage growth of young workers and reached the following conclusions first formal company provided onthe job training on jt appears to be highly firm specific in the united states and therefore is not portable from employer to employer company provided training raises wages in the current job but has no effect on the wages earned in subsequent employment second formal off the job training off jt received from for profit proprietary institutions has little effect on the wages earned on the current job but it does raise the expected wage in subsequent employment finally there are important differences by race gender and education level in the probability of receiving different types of formal training and in the impact this training has on wages and wage growth these findings have several implications for the impact of training on mobility one implication is that if company provided training is primarily firm specific then the probability of leaving an employer should decline if a young worker has experienced some on jt an additional implication is that if a worker participates in an off jt program it appears that the worker should be more likely to leave the current employer in this case off jt allows a young worker to change career paths and find a better match using data from the national longitudinal survey youth nlsy cohort this paper examines in detail the factors that influence the probability of new entrants leaving their first job including the differential effects of company provided training apprenticeships and training from for profit proprietary institutions
