disentangling the college wage premium estimating a model with endogenous education choices this article proposes and empirically implements a structural model of education choices and wage determination to quantitatively evaluate the contributions of productivity enhancement and ability signaling in the college wage premium the model is estimated under various distributional parameterizations using 1990 u s census 5 public use micro sample under these parameterizations i find that college education enhances attendees productivity by about 40 and productivity enhancement accounts for close to two thirds of the college wage premium

using employer hiring behavior to test the educational signaling hypothesis this paper presents a test of the educational signaling hypothesis if employers use education as a signal in the hiring process they will rely more on education when less is otherwise known about applicants we nd that employers are more likely to lower educational standards when an informal more informative recruitment channel is used so we conclude that education is used as a signal in the hiring process

the role of multilateral institutions in international trade cooperation the world trade organization wfo lacks the power to directly enforce agreements it is therefore important to understand what role the wto can play to facilitate international cooperation and whether a multilateral institution can offer distinct advantages over a web of bilateral agreements this paper examines two potential benefits of a multilateral trade institution first verifying violations of the agreements and informing third parties thus facilitating multilateral reputation mechanisms second promoting multilateral trade negotiations rather than a web of bilateral negotiations the model suggests that a multilateral approach is particularly important when there are strong imbalances in bilateral trading relationships

job market signaling and returns to education we compare two partially separating equilibria in a job market signaling model with unproductive education we find that in one of the two equilibria the fraction of the population with a threshold education level is higher even though the cost of education is higher moreover compared to the other equilibrium the population faces a higher threshold education level yet the educated attain lower wages the reason for this result is that the gross return to education can be higher despite the higher cost of education and a higher threshold

multitask agency problems focus and task clustering abstract this short paper discusses recent insights of multitask agency theory it considers in turn the issues of effort substitution conflicts between tasks and implicit incentives and mission it concludes by addressing the problem of optimal task clustering

executive effort and selection of risky projects this article examines the incentives of executives to adopt risky projects the agency problem considered is that of motivating the executive to expend effort to generate information about the profitability of projects and to select the best project conditional upon the information that his effort generates we show that the executive and the principal will not always agree regarding which project is best we provide conditions under which this conflict of interest leads from the principal s perspective to either an underinvestment or an overinvestment in risky projects

human capital versus sorting the effects of compulsory attendance laws under the educational sorting hypothesis a state compulsory school attendance law will increase the educational attainment of high ability workers who are not directly affected hy the law under the human capital hypothesis such laws affect only those individuals whose hehavior is directly constrained we find that compulsory attendance laws do increase enrollment rates in age groups they do not affect directly thus our results contradict the human capital hypothesis and are consistent with the sorting hypothesis i introduction the last decade has seen considerable debate between supporters of the human capital and sorting models of education the former assert that the effect of education on wages reflects increased productivity the latter maintain that it reflects at least in part correlation between education and unobserved ability workers use education to signal their ability while employers use education to screen workers despite the importance of the debate no fully convincing tests of the hypotheses have been developed in fact many members of the profession maintain at least privately that these hypotheses cannot be tested against each other and that the debate must therefore be relegated to the realm of ideology in this paper we show that the models can be tested against each other by examining the effects of state compulsory school attendance laws we show that under the human capital hypotheis such laws will affect the educational attainment only of those who in the absence of the law would have left school prior to the minimum school leaving age on the other hand under the sorting hypothesis the effects of the law will percolate through the system increasing educational attainment even among workers not directly constrained by the law our results are consistent with the predictions of the sorting model

an agency theory of the division of managerial labor should responsibility for strategic planning and execution be assigned to the same manager should a firm have a chief operating officer with responsibilities distinct from those of the chief executive officer how does the division of labor affect managerial opportunism this paper uses a formal agency theoretic model to address these questions and present a new theory of the division of managerial labor building on penrose s typology penrose e 2009 the theory of the growth of the firm 4th ed blackwell oxford uk the theory identifies when to assign i entrepreneurial services which relate to strategic planning and the acquisition of resources and ii managerial services which relate to execution to the same generalist manager rather than to different specialists the analysis reveals the critical importance of separability i e whether a supervisor can separately observe the outcomes of entrepreneurial and managerial services if managers and their supervisor have symmetric information about separability hiring a generalist dominates because managerial services which are easier to assess reduce the scope for opportunism associated with entrepreneurial services which are harder to assess conversely if managers have better information regarding separability and the probability of separability is low hiring specialists dominates because hiring a generalist allows the potential for opportunism associated with entrepreneurial services to contaminate the provision of managerial services even so the benefits of hiring a generalist may be restored if the services are sequenced appropriately an implication of such sequencing is that a firm will grow in fits and starts giving rise to a penrose effect even if labor market frictions do not impede the assimilation of new managers

the trade effects of us anti dumping actions against china post wto entry since china s entry into the wto us anti dumping ad actions against china have increased particularly with respect to multiple petitions distinguishing between us single and multiple petitions we examine the trade effects of us ad actions against china based on an unbalanced panel of quarterly trade data the results show that a us single petition investigation greatly restrains us imports of the filed products from china but also causes more significant import diversion from non named countries in the short run a preliminary ad duty imposed on china via a us multiple petition not only restrains us imports of the filed products from china but also prevents trade diversion from non named countries in the long run a final ad duty on china resulting from a us multiple petition creates a larger destructive effect on china and causes us import diversion from non named countries thus a final ad duty imposed on china following a us multiple petition not only harms china s exports but also fails to help the us achieve import substitution furthermore we have been able to reveal the negative trade effect of a preliminary ad duty even in cases where the ultimate decision is not to impose a final duty

trade deflection and trade depression this is the first paper to empirically examine whether a country s use of an import restricting trade policy distorts a foreign country s exports to third markets we first develop a theoretical model of worldwide trade in which the imposition of antidumping and safeguard taris or trade remedies by one country causes significant distortions in world trade flows we then empirically test this model by investigating the eect of the united states use of such import restrictions on japanese exports of roughly 4800 products into 37 countries between 1992 and 2001 our estimation yields evidence that us restrictions both deflect and depress japanese export flows to third countries imposition of a us antidumping measure against japan deflects trade as the average antidumping duty on japanese exports leads to a 5 7 increase in japanese exports of the same product to the average third country market the imposition of a us antidumping measure against a third country depresses trade as the average us duty imposed on a third country leads to a 5 19 decrease in japanese exports of that same product to the average third country s market we also document the substantial variation in trade deflection and trade depression across dierent importing countries and exported products

the architecture of economic systems hierarchies and polyarchies the authors present new ways of looking at economic organizations andsystems individuals judgments entail errors they sometimes reject good projects and accept bad projects the architecture of an economicsystem specifying how the decision making units are organized togetherwithin a system who gathers what information and who communicates what with whom affects its performance both because it influences thenature of errors that individuals make within the system and becauseit has a critical effect on the aggregation of individuals errors theperformance of two polar architectures decentralized polyarchical versus centralized hierarchical decision making authorities are analyzed and compared copyright 1986 by american economic association

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

an efficient frontier in organization design organizational structure as a determinant of exploration and exploitation this paper develops a parsimonious process level theory that connects organizational structure to exploration and exploitation toward this end it develops a mathematical model of organizational decision making that combines an information processing approach in the spirit of sah and stiglitz sah rk stiglitz je 1986 the architecture of economic systems hierarchies and polyarchies amer econom rev 764 716 727 with elements from signal detection theory the model is first used to explore a design space of organizations and identify trade offs and dominance relationships among alternative organization designs the paper then studies open questions in the organization design literature such as the extent to which exploration and exploitation can be produced by one organization and what is the effect of organization size on exploration more broadly this research speaks to calls for the introduction of more process level explanations in the organizations literature the paper concludes with testable hypotheses and managerially relevant insights

explaining organizational diseconomies of scale in r d agency problems and the allocation of engineering talent ideas and effort by firm size the comparative efficiency and success of small firms in r d remains largely unexplained this paper empirically examines scale diseconomies in offering employment contracts as an explanation for diseconomies of scale in r d the paper argues that small firms more efficiently resolve the severe agency problems of hidden information and hidden behavior in r d small firms more efficiently offer contracts that reward performance than large firms and consequently small firms attract and retain engineers with higher ability and skill further small firms through these more performance contingent contracts induce higher levels of effort than large firms the study tests and generally confirms these hypotheses using data collected from 912 current and former engineering employees of two large high technology companies

the provision of incentives in firms i ncentives are the essence of economics despite many wide ranging claims about their supposed importance there has been little empirical assessment of incentive provision for workers the purpose of this paper is to critically overview existing work on the provision of incentives since the interests of workers and their employers are not always aligned a large theoretical literature has emphasized how firms design compensation contracts to induce employees to operate in the firm s interest this literature has reached into many areas of compensation and has pointed to a multitude of different mechanisms that can be used to induce workers to act in the interests of their employers these include piece rates options discretionary bonuses promotions profit sharing efficiency wages deferred compensation and so on my objective here is to evaluate this literature in the light of a growing empirical literature on compensation where possible i will address the literature from two perspectives first an underlying assumption of this literature is that individuals respond to contracts that reward performance accordingly i consider whether agents behave in this way and whether these responses are always in the firm s interest second i address whether firms write contracts with these responses in mind in other words do contracts look like the predictions of the theory incentives are provided to workers

the political economy of administered protection trade restrictions are hardly ever voted directly by congress though the threat of direct congressional action is frequently present pressure for protection is usually applied through the major instruments for the administrative regulation of imports the antidumping and countervailing duty procedures and the escape clause mechanism in this paper we will examine these instruments for the administrative regulation of imports the form of the paper is not novel a theory of how these mechanisms work is developed then operational implications of this theory are deduced and tested over the record of countervailing duty antidumping and escape clause cases decided from 1975 through 1979 this is the period over which the trade act of 1974 was in force because the nature of these mechanisms is relatively unfamiliar a relatively large amount of institutional information is provided

rules or politics an empirical analysis of itc anti dumping decisions this research analyzes the international trade commission s anti dumping decisions from 1980 to 1986 the results suggest that commissioners use criteria consistent with the instructions set forth in u s legislation the analysis also indicates that political variables help predict commissioner decisions petitions involving senate oversight committee members constituencies may be systematically favored in the process evidence of possible bias toward less developed country exports is presented as well the methodology also yields estimates of commissioner specific fixed effects

welfare costs of the u s antidumping and countervailing duty laws abstract the antidumping ad and countervailing duty cvd laws in the united states have become the most pervasive form of import relief sought by domestic producers this paper estimates the collective economic effect of the hundreds of active u s ad cvd orders using a computable general equilibrium model we estimate that the collective net economic welfare cost in 1993 of these orders to be 4 billion this welfare estimate is sensitive to various modeling assumptions which are explored in the paper with the implementation of the uruguay round agreements the ad cvd laws remain one of the costliest programs restraining u s trade

dynamic tariffs with asymmetric information recent developments in dynamic game theory are applied to determine when two countries can sustain freer trade given that they determine trade policies non cooperatively countries know their own level of protection but not the other country s level of protection using import trigger strategies cooperation in the form of low tariffs can be supported although there are periodic reversionary high tariff episodes however if terms of trade trigger strategies are used cooperation does not occur

on evaluation costs in strategic factor markets the implications for competition and organizational design this paper uses a formal model to study how evaluation costs affect competition for resources in strategic factor markets it finds that relative scarcity may not always benefit resource sellers rather when competition among resource investors passes a certain threshold intensity miscoordination among investors increases to the point that sellers expected profits decline this paper extends the model to consider how investors organize to overcome managerial agency in resource evaluation two organizational designs are considered a incentivization wherein a lower level manager is motivated by an incentive contract to evaluate resources for an investor and b supervision wherein evaluation is either handled directly or closely monitored by headquarters the model suggests that competition among investors will be associated with a greater use of supervision and that investors using supervision will tend to make lower offers this paper also finds that supervision will be more common when valuable resources are rare this paper was accepted by bruno cassiman business strategy

the firm as a communication network this paper analyzes how organizations can minimize costs of processing and communicating information communication is costly because it takes time for an agent to absorb new information sent by others agents can reduce this time by specializing in the processing of particular types of information when these returns to specialization outweigh costs of communication it is efficient for several agents to collaborate within a firm it is shown that efficient networks involve centralization that individuals delegate tasks to subordinates only if they are overloaded and that the number of transits to the top tends to be equalized across individual information items

learning to contract evidence from the personal computer industry organizational forms involving more detailed contracts than are found in traditional spot market exchanges appear to be increasingly prevalent there has been relatively little analysis however of the extent to which firms learn how to use contracts to manage their interfirm relationships over time in this paper we conduct a detailed case study of a time series of 11 contracts concluded during 1989 1997 between the same two partners both of whom participate in the personal computer industry to explore whether and how firms learn to contract we find many changes to the structure of the contracts that cannot be fully explained by changes in the assets at risk in the relationship and evidence that these changes are largely the result of processes in which the firms were learning how to work together including learning how to contract with each other the nature of this learning appears to have been quite incremental and local that is not very far sighted we suggest how and when contracts might serve as repositories for knowledge about how to govern collaborations and suggest some boundary conditions for this phenomenon our findings also provide implications for the debate about whether contracts have a positive or negative effect on interorganizational trust we conclude with suggestions for future research

a procedure for testing the signalling hypothesis abstract this paper develops a procedure for testing the signalling hypothesis as advanced by spence et al the approach used is to examine directly the question of whether employers use education for purely informational purposes in their hiring decisions an application of the method to a recruitment by the swedish auto manufacturer volvo is presented

antidumping and retaliation threats abstract we propose and test two ways in which retaliation threats may dampen the antidumping ad activity we observe first the threat of retaliatory ad actions may make a domestic industry less likely to name a foreign import source in an ad petition second the prospect of a gatt wto trade dispute may make government agencies less likely to rule positive in their ad decision using a nested logit framework we find evidence that both retaliation threats substantially affect us ad activity from 1980 through 1998

the rise of us anti dumping activity in historical perspective empirical studies of anti dumping activity focus almost exclusively on the period since 1980 this paper puts recent us anti dumping experience in historical context by studying the determinants of annual case filings over the past half century the conventional view that few anti dumping cases existed prior to 1980 is not correct although most did not result in the imposition of duties the increased number of cases in recent decades largely reflects petitions that target multiple source countries the number of imported products involved has actually fallen since the mid 1980s the annual number of anti dumping cases is influenced by the unemployment rate the exchange rate import penetration closely related to the decline in average tariffs and changes in the anti dumping law and its enforcement in the early 1980s

the division of labor coordination costs and knowledge this paper considers specialization and the division of labor a more extensive division of labor raises productivity because returns to the time spent on tasks are usually greater to workers who concentrate on a narrower range of skills the traditional discussion of the division of labor emphasizes the limitations to specialization imposed by the extent of the market we claim that the degree of specialization is more often determined by other considerations especially emphasized are various costs of coordinating specialized workers who perform complementary tasks and the amount of general knowledge available
