structural causes and regime consequences regimes as intervening variables international regimes are defined as principles norms rules and decisionmaking procedures around which actor expectations converge in a given issue area as a starting point regimes have been conceptualized as intervening variables standing between basic causal factors and related outcomes and behavior there are three views about the importance of regimes conventional structural orientations dismiss regimes as being at best ineffectual grotian orientations view regimes as an intimate component of the international system and modified structural perspectives see regimes as significant only under certain constrained conditions for grotian and modified structuralist arguments which endorse the view that regimes can influence outcomes and behavior regime development is seen as a function of five basic causal variables egoistic self interest political power diffuse norms and principles custom and usage and knowledge

on the demographic composition of colleges and universities in market equilibrium achieving diversity in the racial and ethnic makeup of the student body is one of the objectives that a college pursues in making decisions about admission and financial aid there has been a tremendous amount of debate about policies that colleges should adopt or be proscribed from adopting with respect to diversity rather than join this largely normative debate we adopt a positive focus investigating how colleges quests for ethnic and racial diversity affect admission and financial aid policies the college quality hierarchy and the distribution of whites and nonwhite students across colleges of differing qualities we provide a theoretical framework for investigating the effects of preferences for diversity augmented with results from a parallel computational model calibrated to u s data the effects of efforts to achieve diversity in colleges depend not only on the weight that colleges give to diversity but also on the value that prospective students place on diversity diversity may be of concern to no one only to colleges to both colleges and students or to colleges and a subset of students we first describe a baseline model without preferences for diversity and then examine three alternatives in which preferences for racial diversity are present

an evolutionary approach to norms iorms provide a powerful mechanism for regulating conflict in groups even when there are more than two people and no central authority this paper investigates the emergence and stability of behavioral norms in the context of a game played by people of limited rationality the dynamics of this new norms game are analyzed with a computer simulation based upon the evolutionary principle that strategies shown to be relatively effective will be used more in the future than less effective strategies the results show the conditions under which norms can evolve and prove stable one interesting possibility is the employment of metanorms the willingness to punish someone who did not enforce a norm many historical examples of domestic and international norms are used to illustrate the wide variety of mechanisms that can support norms including metanorms dominance internalization deterrence social proof membership in groups law and reputation

do regimes matter epistemic communities and mediterranean pollution control international regimes have received increasing attention in the literature on international relations however little attention has been systematically paid to how compliance with them has been achieved an analysis of the mediterranean action plan a coordinated effort to protect the mediterranean sea from pollution shows that this regime actually served to empower a group of experts members of an epistemic community who were then able to redirect their governments toward the pursuit of new objectives acting in an effective transnational coalition these new actors contributed to the development of convergent state policies in compliance with the regime and were also effective in promoting stronger and broader rules for pollution control this suggests that in addition to providing a form of order in an anarchic international political system regimes may also contribute to governmental learning and influence patterns of behavior by empowering new groups who are able to direct their governments toward new ends

alliances in international governmental organizations regional trade agreement formation and multinational enterprise regionalization strategy abstract drawing from political science alliance theories we explain why countries are likely to enter regional trade agreements we argue that the probability that this will happen is higher if the countries are allies in the same international governmental organizations igos as such alliances can help build trust and reduce political risk our results show that igo scope and also partner reliability and influence in the igo network play important roles our findings provide guidance to multinational enterprises in formulating regionalization strategies

affirmative action in education evidence from engineering college admissions in india abstract this paper examines an affirmative action program for lower caste groups in engineering colleges in india we study both the targeting properties of the program and its implications for labor market outcomes we find that affirmative action successfully targets the financially disadvantaged the upper caste applicants that are displaced by affirmative action come from a richer economic background than the lower caste applicants that are displacing them targeting by caste however may lead to the exclusion of other disadvantaged groups for example caste based targeting reduces the overall number of females entering engineering colleges we find that despite poor entrance exam scores lower caste entrants obtain a positive return to admission our estimates however also suggest that these gains may come at an absolute cost because the income losses experienced by displaced upper caste applicants are larger than the income gains experienced by displacing lower caste students limited sample sizes in our preferred econometric specifications however prevent us from drawing strong conclusions from these labor market findings

delegation to international organizations agency theory and world bank environmental reform current international relations theory struggles to explain both the autonomy and transformation of international organizations ios previous theories either fail to account for any io behavior that deviates from the interests of member states or neglect the role of member states in reforming io institutions and behavior we propose an agency theory of ios that can fill these gaps while also addressing two persistent problems in the study of ios common agency and long delegation chains our model explains slippage between member states interests and io behavior but also suggests institutional mechanisms staff selection monitoring procedural checks and contracts through which states can rein in errant ios we evaluate this argument by examining multiple institutional reforms and lending patterns at the world bank from 1980 to 2000

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

does affirmative action work caste gender college quality and academic success in india public policy in modern india features affirmative action programs intended to reduce inequality that stems from a centuries old caste structure and history of disparate treatment by gender we study the effects of one such affirmative action program an admissions policy that fixes percentage quotas common across more than 200 engineering colleges for disadvantaged castes and for women we show that the program increases college attendance of targeted students particularly at relatively higher quality institutions an important concern is that affirmative action might harm intended beneficiaries by placing them in academic programs for which they are ill prepared we find no evidence of such adverse impacts

will affirmative action policies eliminate negative stereotypes a key question concerning affirmative action is whether the labor market gains it brings to minorities can continue without it becoming a permanent fixture in the labor market the authors argue that this depends on how the policy affects employers beliefs about the productivity of minority workers they study the joint determination of employer beliefs and worker productivity in a model of statistical discrimination in job assignments the authors prove that even when identifiable groups are equally endowed ex ante affirmative action can bring about a situation in which employers correctly perceive the groups to be unequally productive ex post copyright 1993 by american economic association

nuclear learning and u s soviet security regimes the concepts of regimes and learning have been developed in the liberal theory of international relations but their application has been mostly in the area of international political economy u s soviet relations are generally explained solely in terms of realist theory the dichotomy is unfortunate because both strands of theory have something to contribute although the injunctions of an overall regime do not govern the u s soviet security relationship it is possible to identify the injunctions and constraining effects of regimes in subissues of the security relationship in five areas of the nuclear relationship destructive power control problems proliferation arms race stability and deterrent force structure it is possible to identify different degrees of learning and to see how such learning affects and is affected by the development of regimes looking at the u s soviet security relationship in terms of learning and regimes raises new questions and opens a research agenda which helps us to think more broadly about the processes of political change in this area

the enforcement of equal opportunity laws under imperfect information affirmative action and alternatives more than twenty years have passed since the enactment of the civil rights act during that period the enforcement of title vii with its broad prohibition of discrimination in employment and compensation has proved to be both difficult and controversial as part of any attempt to regulate economic activity we must be able to observe violations but unequal treatment in employment relationships is difficult to identify employers must always differentiate between individuals when making hiring and promotion decisions since applicants possess diverse skills and abilities this diversity creates a fundamental problem in monitoring the compliance or noncompliance of employers with equal opportunity laws this paper examines the enforcement of equal opportunity laws in a labor market that exhibits statistical discrimination this type of discrimination may arise as a rational response by profitmaximizing firms to imperfect information about individual productivity in lundberg and startz 1983 an equal opportunity policy prohibiting raceor sex specific wage schedules was shown to be an efficiency enhancing response to statistical discrimination section ii extends this model to allow information a role in allocating heterogeneous workers among jobs in this environment restricting firms use of information through an equal opportunity policy improves workers incentives to acquire human capital at the expense of production losses and its net effect on efficiency becomes ambiguous firms will attempt to evade an equal opportunity law presenting the government and the courts with the task of monitoring and enforcing compliance the regulators are likely to possess imperfect information not only about the relationship between worker characteristics and productivity but also about the actual personnel policies followed by firms in section iii a simple costminimizing evasion policy for firms in which other worker attributes are used as imperfect proxies for race or sex is outlined in the next two sections alternative policies for enforcing compliance

the theory of collective action and burden sharing in nato mancur olson s theory of collective action could account for much of the variance in the defense burdens of the allied nations of the north atlantic treaty organization nato in the early years of the cold war but the association between economic size gross domestic product or gdp and defense burden the ratio of military expenditures to gdp has declined to insignificant levels two influences are shown to be important in producing this change the increased pursuit of private goods by greece turkey and portugal and the growing cooperation among the other european allies since cooperation in the military realm has not provided the europeans with credible means of self defense it appears to be a consequence of the general growth of interdependence in europe during the postwar period nato is still essentially a uniquely privileged group producing a relatively pure public good accordingly the theory of collective action continues to provide valuable insights into the operation of the alliance

testing for structural breaks trade off between power and spurious effects abstract i argue that in order to test for the effect of the foundation of the federal reserve on the behavior of short term interest rates extending the sample size on either side of the interval 1908 1918 will generate spurious results mankiw miron and weil 1987 1994 do not address data problems pointed out by other authors nor do they take into account some historical events and institutional changes in the new york money market that had an impact on the behavior of short term interest rates given these reasons for restricting the sample size i argue that their monte carlo evidence is largely irrelevant to the issue and that lack of power confirms my claim that no regime change can be detected astride the foundation of the fed

explaining the non proliferation regime anomalies for contemporary international relations theory this article reconciles common policy usage with scholarly definition the system of cooperation on non proliferation has often been termed an international regime but there has not been any systematic effort to determine if this is actually true the discussion also attempts to reconcile the formation and maintenance of this system of cooperation with contemporary international relations theory the central argument is that the system of international cooperation on non proliferation does constitute a regime but that such a regime presents a serious anomaly for contemporary theory the article concludes that power and egoistic self interest are inadequate to account for the regime s formation and maintenance the inadequacies of both the hegemonic stability and functional theories point towards another independent variable that needs central consideration in regime analysis knowledge and learning

disciplining trade finance the oecd export credit arrangement the salience of tariffs quotas and other import restrictions in current discussions of trade policy obscures what may well become a more significant form of government intervention subsidized export promotion over the past two decades subsidized trade finance has been one of the most widely used instruments of export promotion this article offers an historical description and a theoretical explanation for the success of the organization for economic cooperation and development oecd export credit arrangement an international regime restricting the provision of subsidized trade finance the explanation emphasizes three factors the structure of government institutions the relative power of states and the functional value of information more generally the analysis demonstrates the inherent weaknesses of monocausal explanations of international cooperation and the advantages of explanations based on a conception of international cooperation as a multistage process each stage of which may be explained by a separate theory

a general equilibrium model of statistical discrimination we study a general equilibrium model with endogenous human capital formation in which ex ante identical groups may be treated asymmetrically in equilibrium the interaction between an informational externality and general equilibrium effects creates incentives for groups to specialize discrimination may arise even if the corresponding model with a single group has a unique equilibrium the dominant group gains from discrimination rationalizing why a majority may be reluctant to eliminate discrimination the model is also consistent with reverse discrimination as a remedy against discrimination since it may be necessary to decrease the welfare of the dominant group to achieve parity

international regimes and alliance behavior explaining nato conventional force levels with the end of the cold war the military posture of the north atlantic treaty organization nato has entered a period of profound change prior to the recent dramatic political events in europe however nato conventional force levels in the central region had been remarkably stable for some three decades this article seeks to explain this record of stability in terms of three widely used theories of international relations it argues that balance of power theory and public goods theory cannot alone provide a satisfactory account rather these traditional approaches for understanding alliance behavior must be supplemented by regime theory which emphasizes the constraining effects of enduring institutional factors even in the face of structural change specifically it shows how an international regime has influenced the provision of conventional forces in the central region by alliance members more generally this analysis seeks to contribute to the literature on international regimes in three ways first it demonstrates that regimes do matter by providing an example of their importance for explaining state behavior and international outcomes second it extends regime theory to relations among military allies third it elaborates a comprehensive model for understanding why states actually comply with regime injunctions the model stresses both the ways in which regimes effectively modify the international environment within which states operate altering the costs and benefits associated with different courses of action and the ways in which participating states may internalize regime norms and rules thereby making compliance increasingly automatic

affirmative action in a competitive economy abstract we consider a model of endogenous human capital formation with competitively determined wages discrimination is sustainable in equilibrium in the presence of two distinguishable but ex ante identical groups of workers an affirmative action policy consisting of a quota may fail in the sense that there still may be equilibria where groups are treated differently however the incentives to invest for agents in the discriminated group are improved by affirmative action if the initial equilibrium is the most discriminatory equilibrium in the model without the policy the welfare effects are ambiguous it is possible that the policy makes the intended beneficiaries worse off even if the starting point is the most discriminatory equilibrium the expected payoff may decrease for all agents in the target group

peer effects teacher incentives and the impact of tracking evidence from a randomized evaluation in kenya to the extent that students benefit from high achieving peers tracking will help strong students and hurt weak ones however all students may benefit if tracking allows teachers to better tailor their instruction level lower achieving pupils are particularly likely to benefit from tracking when teachers have incentives to teach to the top of the distribution we propose a simple model nesting these effects and test its implications in a randomized tracking experiment conducted with 121 primary schools in kenya while the direct effect of highachieving peers is positive tracking benefited lower achieving pupils indirectly by allowing teachers to teach to their level jel i21 j45 o15

affirmative action and the quality fit trade off this paper reviews the literature on affirmative action in undergraduate education and law schools focusing especially on the trade off between institutional quality and the fit between a school and a student we discuss the conditions under which affirmative action for underrepresented minorities urm could help or harm their educational outcomes we provide descriptive evidence on the extent of affirmative action in law schools as well as a critical review of the contentious literature on how affirmative action affects urm law school student performance our review then discusses affirmative action in undergraduate admissions focusing on the effects such admissions preferences have on college quality graduation rates college major and earnings we conclude by examining the evidence on percent plans as a replacement for affirmative action

global communications and national power life on the pareto frontier regime analysis has focused on issues of market failure the resolution of which depends upon knowledge and institution building global communications regimes however have been concerned either with issues of pure coordination or with coordination problems with distributional consequences outcomes have been decided by the underlying distribution of national power in those areas where power was asymmetrically distributed and there was no agreement on basic principles and norms radio broadcasting and remote sensing no regime was formed in those areas where distributional issues could not be unilaterally resolved allocation of the radio spectrum and telecommunications regimes were created although both principles and rules changed with alterations in national power capabilities

admission tuition and financial aid policies in the market for higher education we present an equilibrium model of the market for higher education our model simultaneously predicts student selection into institutions of higher education financial aid educational expenditures and educational outcomes we show that the model gives rise to a strict hierarchy of colleges that differ by the educational quality provided to the students we also develop a new estimation procedure that exploits the observed variation in prices within colleges identification is based on variation in endowments and technology it does not rely on observed variation in potentially endogenous characteristics of colleges such as peer quality measures and expenditures we estimate the structural parameters using data collected by the national center for education statistics and aggregate data from peterson s and the national science foundation
