a dynamic model of welfare reform a dynamic structural model of labor supply welfare participation and food stamp participation is estimated using the 1992 1993 and 1996 panels of the survey of income and program participation details of various policies including welfare time limits work requirements and earned income tax credit eitc are incorporated formally in the budget constraint policy simulations reveal that the economy accounts for half of the increase in the labor supply of female heads of family between 1992 and 1999 a time limit results in a larger efficiency gain than a work requirement or a direct reduction in welfare benefits a reform package can lead to both a reduction in the government expenditure and an improvement in utility the eitc expansion results in a substantial efficiency gain among individuals with the lowest expected wage these individuals are almost unaffected by the economic expansion but their income and utility increase significantly under the reform package

temptation and social security in a dynastic framework abstract we investigate welfare and aggregate implications of a pay as you go payg social security system in a dynastic framework in which individuals have self control problems the presence of self control problems induces individuals to save less because of their urge for temptation towards current consumption individuals efforts to balance between the short term urge for temptation and the long term commitment for consumption smoothing result in self control costs in this environment payg social security works as a self control cost reducing device in contrast the presence of altruism induces individuals to save more this in turn mitigates the adverse effects of self control problems and payg social security on savings but magnifies the self control costs we find that in our environment the adverse welfare effects of a payg system are further mitigated relative to the environments that incorporate altruism and self control issues separately however the level of mitigation is quite modest

meta paradigm change and the theory of the firm many seemingly unrelated debates on the theory of the firm are in fact part of a single deeper transformation of the social sciences as the foundational assumptions of 20th century social science have slowly been shown by science to be false new sub paradigms have emerged which cumulatively drop i theoretical assumptions about markets to explain firms ii epistemological assumptions about knowledge to explain diversity and iii metaphysical assumptions about causality to explain technical change debates occur across each of these levels

entrepreneurial rents and the theory of the firm abstract the creation of entrepreneurial rents occurs under conditions of uncertainty yet current theories of rent appropriation such as transactions cost theories of the firm focus their efforts primarily on how quasi rents rents that have already been created are appropriated by parties to that exchange entrepreneurs face a dual challenge that of creating entrepreneurial rents and appropriating some of these rents moreover this challenge usually exists at a time when the entrepreneurial rents that might be created are not known or anticipatable indeed entrepreneurs not only concern themselves with ensuring that they are able to appropriate at least some of the rents that might be eventually created but in fact they may not create any rents or potentially lose value understanding the dual nature of the rent creation and the rent appropriation problem has a variety of implications for the study of entrepreneurial organizations and generally for theory of the firm discussions

female labour supply and marital status decisions a life cycle model this paper studies the interdependence between and the determinants of life cycle marital status and labour force participation decisions of women a dynamic utility maximization model is presented and estimated using longitudinal data on women from the panel study of income dynamics the mle method employed involves solving a dynamic programming problem further a minimum distance estimator is proposed which allows for the incorporation of wage data in a computationally simple way the estimates are used to predict changes in the life cycle patterns of employment marriage and divorce due to differences in education race the female s earnings and her potential husband s earnings the estimation results indicate that the utility gains to marriage are decreasing in the female s wage rate and increasing in her potential husband s earnings while the opposite is found for gains to working ignoring the endogeneity of marital status decisions is shown to lead to an underestimation of own and husband s wage effects on female labour supply

high school experiences the gender wage gap and the selection of occupation abstractusing within high school variation and controlling for a measure of cognitive ability this article finds that high school leadership experiences explain a significant portion of the residual gender wage gap and selection into management occupations our results imply that high school leadership could build non cognitive productive skills that are rewarded years later in the labour market and that explain a portion of the systematic difference in pay between men and women alternatively high school leadership could be a proxy variable for personality characteristics that differ between men and women and that drive higher pay and becoming a manager because high school leadership experiences are exogenous to direct labour market experiences our results leave less room for direct labour market discrimination as a driver of the gender wage gap and occupation selection

job search and hyperbolic discounting structural estimation and policy evaluation this paper estimates the structural parameters of a job search model with hyperbolic discounting and endogenous search effort it estimates quantitatively the degree of hyperbolic discounting and assesses its implications for the impact of various policy interventions aimed at reducing unemployment the model is estimated using data on unemployment spells and accepted wages from the national longitudinal survey of youth nlsy the likelihood function explicitly incorporates all the restrictions implied by the optimal dynamic programming solution to the model both observed and unobserved heterogeneity are accounted for the results point to a substantial degree of hyperbolic discounting especially for low and medium wage workers the structural estimates are also used to evaluate alternative policy interventions for the unemployed estimates based on a model with exponential discounting may lead to biased inference on the economic impact of policies jel c6 c73 d90 j64 j68

spillovers and governance an analysis of knowledge and reputational spillovers in information technology investigating spillovers potential costs and benefits to a firm that extend beyond an individual transaction i integrate transaction cost theory and the knowledge based view of the firm in an effort to better understand the efficient governance of knowledge contracts with detailed task descriptions were associated with transactions with the potential to generate new and reusable knowledge the risk of a firm s technology spilling over to others and the risk of reputation impairing spillovers were associated with suppliers using their own employees rather than subcontractors thus results suggest that the creation and protection of knowledge are key factors in understanding governance decisions

job search and impatience workers who are more impatient search less intensively and set lower reservation wages the effect of impatience on exit rates from unemployment is therefore unclear if agents have exponential time preferences the reservation wage effect dominates for sufficiently patient individuals so increases in impatience lead to higher exit rates the opposite is true for agents with hyperbolic time preferences using two large longitudinal data sets we find that impatience measures are negatively correlated with search effort and the unemployment exit rate and are orthogonal to reservation wages impatience substantially affects outcomes in the direction predicted by the hyperbolic model

carrot and stick how reemployment bonuses and benefit sanctions affect exit rates from welfare summary to increase the exit from welfare benefit recipients in the municipality of rotterdam were exposed to various financial incentives once their benefit spell exceeded one year welfare recipients were entitled to a re employment bonus if they found a job that lasted at least 6 months however they could also be punished for noncompliance with eligibility requirements and face a sanction i e a temporary reduction of their benefits we find that the financial sticks in the form of benefit sanctions were effective in stimulating the exit from welfare while the financial carrots in the form of re employment bonuses were not copyright 2011 john wiley sons ltd

strategy research governance and competence perspectives business strategy is a complex subject and is usefully examined from several perspectives this paper applies the lenses of governance and competence to the study of strategy both the governance and the competence perspectives have had the benefit of distinguished antecedents they have also had to deal with tautological reputations i begin with the governance perspective with emphasis on the six key moves through which it has been operationalized i then examine the competence perspective in these same six respects governance challenges the competence perspective to apply itself more assiduously to operationalization including the need to choose and give definition to one or more units of analysis of which the routine is a promising candidate the research challenges posed by competence to which governance can and should respond include dynamic transaction costs learning and the need to push beyond generic governance to address strategy issues faced by particular firms with their distinctive strengths and disabilities a lively research future for these two perspectives individually and in combination is projected copyright 1999 john wiley sons ltd business strategy is an expansive enterprise not only do all of the functional areas in the business school relate but strategy is by nature interdisciplinary all of the social sciences especially economics and organization theory plus contract law are implicated indeed in the high technology arena where some of the most difficult strategy issues reside engineering and the law on intellectual property rights also have a bearing of the various approaches to the study of strategy this paper focuses on the governance and competence perspectives both perspectives combine economic reasoning with organization theory as between these two the governance

modularity in technology and organization this paper is an attempt to raid both the literature on modular design and the literature on property rights to create the outlines of a modularity theory of the firm such a theory will look at firms and other organizations in terms of the partitioning of rights understood as protected spheres of authority among cooperating parties and it will assert that organizations reflect nonmodular structures that is structures in which decision rights rights of alienation and residual claims to income do not all reside in the same hands 2002 elsevier science b v all rights reserved

disentangling the theories of firm boundaries a path model and empirical test theories on the motivation underlying firm boundaries have recently sparked renewed debate what best explains whether a firm relies on market control or hierarchical control to secure required resources how do the characteristics of the resources come into play in this study we consider a comprehensive path model of the governance mode decision for sourcing technological know how by integrating different perspectives on firm boundaries including transaction cost economics a resource based view and an options perspective we link characteristics of the technology i e uniqueness barriers to imitation commercial uncertainty technological dynamism to the perceived threat of opportunism the potential for sustainable advantage and the pursuit of a licensing agreement vis a vis the outright acquisition of the firm that possesses the desired know how we use structural equation modeling to analyze 127 sourcing arrangements our results show that technological dynamism and barriers to imitation indirectly influence the governance mode decision by increasing the perceived threat of opportunism commercial uncertainty directly influences the governance mode and decreases the likelihood of an acquisition vis a vis a licensing agreement although uniqueness and barriers to imitation are also positively associated with the perceived potential for sustainable advantage the potential for sustainable advantage had no direct effect on governance mode implications and suggestions for further research are offered

paying not to go to the gym how do consumers choose from a menu of contracts we analyze a novel dataset from three u s health clubs with information on both the contractual choice and the day to day attendance decisions of 7 752 members over three years the observed consumer behavior is difficult to reconcile with standard preferences and beliefs first members who choose a contract with a flat monthly fee of over 70 attend on average 4 3 times per month they pay a price per expected visit of more than 17 even though they could pay 10 per visit using a 10 visit pass on average these users forgo savings of 600 during their membership second consumers who choose a monthly contract are 17 percent more likely to stay enrolled beyond one year than users committing for a year this is surprising because monthly members pay higher fees for the option to cancel each month we also document cancellation delays and attendance expectations among other findings leading explanations for our findings are overconfidence about future self control or about future efficiency overconfident agents overestimate attendance as well as the cancellation probability of automatically renewed contracts our results suggest that making inferences from observed contract choice under the rational expectation hypothesis can lead to biases in the estimation of consumer preferences

is addiction rational theory and evidence this paper makes two contributions to the modeling of addiction first we provide new and convincing evidence that smokers are forward looking in their smoking decisions using state excise tax increases that have been legislatively enacted but are not yet effective and monthly data on consumption second we recognize the strong evidence that preferences with respect to smoking are time inconsistent with individuals both not recognizing the true dife culty of quitting and searching for self control devices to help them quit we develop a new model of addictive behavior that takes as its starting point the standard rational addiction model but incorporates time inconsistent preferences this model also exhibits forward looking behavior but it has strikingly different normative implications in this case optimal government policy should depend not only on the externalities that smokers impose on others but also on the internalities imposed by smokers on themselves we estimate that the optimal tax per pack of cigarettes should be at least one dollar higher under our formulation than in the rational addiction case

welfare reform when recipients are forward looking in 1996 the aid to families with dependent children program was replaced with the temporary assistance for needy families tanf program this paper considers the effects of two specific components of tanf time limits and work requirements on employment marriage and welfare participation a discrete choice dynamic programming model is used and parameter estimates are obtained using data from the panel study of income dynamics policy simulations show that a five year lifetime time limit results in a 60 percent reduction in welfare use and that a substantial part of this reduction occurs because recipients are forward looking

the underdetermined knowledge based theory of the mnc in this note we revisit two core propositions of the knowledge based view of the firm found in the seminal work of kogut and zander 1 that multinational corporations mncs exist because transfers and re combinations of knowledge occur more efficiently inside mncs than between mncs and third parties and 2 that the threat of opportunism is not necessary although it may be sufficient to explain the existence of the mnc their knowledge based view shifted the conceptualization of the firm from an institution arising from market failure and transaction costs economizing to a progeny of superior knowledge governance we question these conclusions arguing that firms are but one of the many types of epistemic communities possessing and nurturing procedural norms identity and the cognitive linguistic and reflexive attributes conducive to efficient exchange and re combination of knowledge among their members important insights may be gained by applying the concept of epistemic communities implicit in the knowledge based perspective beyond firm level hierarchies journal of international business studies 2011 42 427 435

does it pay for women to volunteer this article estimates the economic and noneconomic returns to volunteering for prime aged women estimates of a dcdp model indicate that an extra year of volunteer experience increases wage offers by 8 5 in future part time work and by 2 6 in future full time work on average working for free increases lifetime earnings by 16 7 the economic returns to volunteering are more important than the noneconomic returns in increasing lifetime utility the model also reveals an adverse selection mechanism into volunteering that helps explain why reduced form regressions of the returns to working for free will likely be downward biased

time inconsistency and welfare program participation evidence from the nlsy we empirically implement a dynamic structural model of labor supply and welfare program participation for agents with potentially time inconsistent preferences using panel data on the choices of single women with children from the nlsy 1979 we provide estimates of the degree of time inconsistency and of its influence on the welfare take up decision with these estimates we conduct counterfactual experiments to quantify the utility loss stemming from the inability to commit to future decisions and the potential utility gains from commitment mechanisms such as welfare time limits and work requirements

implications of hyperbolic discounting for optimal pricing and scheduling of unpleasant services that generate future benefits people tend to lack the self control to undergo an unpleasant service that would generate future benefits this paper derives a tractable quasi hyperbolic discounting model of that behavioral tendency for a queueing system in which service time is short relative to the time horizon for its benefits planning in advance people may naively overestimate their self control this paper shows how customers lack of self control and naivete affect optimal pricing and scheduling the welfare maximizing usage fee and the revenue maximizing usage fee decrease with customers lack of self control charging for subscription in addition to or instead of per use increases revenue especially when subscribers are naive if the manager can charge for subscription or per use subscription is optimal for revenue maximization whereas usage based pricing is optimal for welfare maximization if customers are heterogeneous in their self control and naivete priority scheduling can dramatically increase welfare and revenu

time inconsistency and alcohol sales restrictions restrictions on alcohol sales hours or days are commonly used tools in order to reduce alcohol consumption however a forward looking consumer can buy in advance thereby mostly undo the impact of the restriction i study whether time inconsistent consumer preferences can provide a justification for restrictions on alcohol sales time i estimate a demand model which allows a fraction of consumers to be time inconsistent using scanner data of beer purchases and other shopping behavior according to the estimation results 20 of consumers are time inconsistent and they account for 64 of beer consumption i find that sunday sales restriction decreases weekend consumption by the same amount as a sales tax increase by 21 percentage points in terms of consumer welfare the sales restriction is preferable to the tax increase

gender role attitudes and the labour market outcomes of women across oecd countries this paper uses data from the world value surveys 1990 1995 1999 to investigate the impact of gender role attitudes and work values on women s labour market outcomes across 25 oecd countries anti egalitarian views are found to display the strongest negative association with female employment rates and the gender pay gap these views are however softening among recent cohorts on the other hand perceptions of women s role as homemakers which are likely formed in youth and linked to religious ideology are more persistent over time they could be implicated in the recent slowdown of the gender convergence in pay finally the unavoidable clash between family values and egalitarian views that takes the form of an inner conflict for many women the so called mother s guilt is another obstacle in the path towards greater gender equality in the labour market copyright 2005 oxford university press

learning across geographic space pro market reforms multinationalization strategy and profitability building on economic geography and knowledge based theory i argue that pro market reforms augment the profitability of firms by increasing their competitiveness and market knowledge however i propose that this effect is greater for firms that operate internationally firms that operate in more advanced markets and firms that become multinationals before reforms are implemented this is because such firms acquire market knowledge abroad that they can use when responding to reforms at home giving them a head start advantage over other local firms the analyses of a panel of the largest 500 latin american companies from 1989 to 2008 provide support for these arguments

policy effects in hyperbolic vs exponential models of consumption and retirement this paper constructs a structural retirement model with hyperbolic preferences and uses it to estimate the effect of several potential social security policy changes estimated effects of policies are compared using two models one with hyperbolic preferences and one with standard exponential preferences sophisticated hyperbolic discounters may accumulate substantial amounts of wealth for retirement we find it is frequently difficult to distinguish empirically between models with the two types of preferences on the basis of asset accumulation paths or consumption paths around the period of retirement simulations suggest that despite the much higher initial time preference rate individuals with hyperbolic preferences may actually value a real annuity more than individuals with exponential preferences who have accumulated roughly equal amounts of assets this appears to be especially true for individuals with relatively high time preference rates or who have low assets for whatever reason this affects the tradeoff between current benefits and future benefits on which many of the retirement incentives of the social security system rest simulations involving increasing the early entitlement age and increasing the delayed retirement credit do not show a great deal of difference whether exponential or hyperbolic preferences are used but simulations for eliminating the earnings test show a non trivially greater effect when exponential preferences are used

the role of labor and marriage markets preference heterogeneity and the welfare system in the life cycle decisions of black hispanic and white women using data from the nlsy79 we structurally estimate a dynamic model of the life cycle decisions of young women the women make sequential joint decisions about school attendance work marriage fertility and welfare participation we use the model to perform counterfactual simulations designed to shed light on three questions 1 how much of observed minority majority differences in behavior can be attributed to differences in labor market opportunities marriage market opportunities and preference heterogeneity 2 how does the welfare system interact with these factors to augment those differences 3 how can new cohorts that grow up under the new welfare system temporary aid for needy families be expected to behave compared to older cohorts

pension design with a large informal labor market evidence from chile this article investigates the fiscal and welfare trade offs involved in designing a pension system when workers can avoid contributing by working informally using a life cycle model of labor supply and saving decisions i structurally estimate preferences and earnings opportunities in the formal and informal sectors using data on chilean households i find limited support for formal jobs rationing instead mandatory pension contributions significantly encourage informality policy experiments show that chile could lower minimum pension spending by 23 while guaranteeing the same income to retirees if the minimum pension s implicit tax rate was increased to 60

an economic model of welfare stigma perhaps the most basic assumption of the economic theory of consumer demand is that more is better than less virtually all of the major propositions of consumer theory can in a certain sense be derived from the assumption that goods are good interestingly however this tenet seems to be violated by the behavior of many individuals in the low income population for many turn out to be eligible for a positive welfare benefit but do not in fact join the welfare rolls for example it has been estimated that in 1970 only about 69 percent of the families eligible for afdc aid to families with dependent children participated in the program see richard michel 1980 the corresponding percentage for afdc u the program for which families with an unemployed male are eligible was only 43 percent and the participation rate in the food stamp program was only 38 percent see maurice mcdonald 1977 this phenomenon has puzzled many investigators because such individuals do not locate on the boundaries of their budget sets consequently most investigators ignore the problem when studying the effects of welfare programs on behavior in this paper this seemingly irrational rejection of an increase in income is modeled as resulting from welfare stigma that is from disutility arising from participation in a welfare program per se 1 the existence of stigma has been amply documented in the sociological literature patrick horan and patricia austin 1974 lee rainwater 1979 where interviews of recipients have often uncovered feelings of lack of self respect and negative self characterizations from participation in welfare nevertheless this phenomenon has not been modeled and many questions consequently remain when is the disutility of participation strong enough to prevent participation shouldn t we expect individuals to weigh the disutility of participation against the potential benefit in their decisions what is the elasticity of participation with respect to the potential benefit also in a slightly different vein how are the work disincentives of welfare affected by stigma these questions have been given scant attention by economists yet they are crucial for our ability to predict the impact of various welfare programs on the lowincome population here these questions are addressed by modeling nonparticipation as a utility maximizing decision the model is developed and estimated for the afdc program 2 the model posits an individual utility function containing not just disposable income but

governance strategies and transaction costs in a renovated electricity market abstract this study applies a transaction cost economics tce framework to examine how economic agents adopt governance strategies in brazil s recently renovated electricity market in light of a well established tce model four attributes of transactions i e asset specificity uncertainty complexity and frequency are examined for three unregulated transactions between generating firms and final consumers the qualitative analysis of attributes unfolds into a comparative analysis of theory predicted governance strategies versus strategies observed in the marketplace it is argued that williamson s model continues to effectively predict the most efficient governance strategy in the sense of minimizing transaction costs and safeguarding idiosyncratic assets misalignment between theory predictions and observations however suggests that two additional concepts implementability and reputation must be examined alongside with williamson s four attributes of transactions in order to better explain strategic decisions in brazil s electricity market capital availability existence of compatible partners and reputation play crucial roles in explaining those decisions

bounded rationality and tacit knowledge in the organizational capabilities approach an assessment and a re evaluation the famous three chapters in nelson and winter s an evolutionary theory of economic change 1982 that focus on firm routines and capabilities are often taken to be solidly founded on an assumption of bounded rationality i argue that in actuality bounded rationality plays a rather limited role in nelson and winter 1982 that the very different assumption of tacit knowledge is much more central and that the links between bounded rationality and routines capabilities are not clear i then argue that the absence in nelson and winter of a clear methodological individualist foundation for notions such as routines capabilities competencies etc has resulted in certain explanatory difficulties in the modern organizational capabilities approach that has taken so much inspiration from their work copyright 2003 oxford university press

strotz meets allais diminishing impatience and the certainty effect abstract decision makers tend to exhibit a higher degree of impatience when considering a delay to an immediate reward than when contemplating an identical delay to an equal future reward this work argues that diminishing impatience originates from the distinction between the certain present and the risky future a simple functional representation of preferences exhibiting time inconsistency when the future is uncertain is derived experimental evidence which is inconsistent with other formulations that account for diminishing impatience supports the proposed approach the new theory uncovers a tight relation between diminishing impatience and well known behavioral regularities in choice under risk and uncertainty jel d12 d81

asymmetric adjustment costs in non linear labour demand models for the netherlands and u k manufacturing sectors the costs of hiring a worker generally differ in size from the firing costs this article investigates optimal labour demand schedules for production and nonproduction workers of firms that operate under uncertainty and face asymmetric costs of adjusting their workforce in the empirical part generalised methods of moments gmm estimates of the structural parameters of the euler conditions for production and nonproduction workers are presented together with specification and structural stability tests using time series data of the netherlands and uk manufacturing sectors we find that asymmetric adjustment costs play an important role in the explanation of unbalanced labour demand between upward and downward movements of the business cycle moreover hiring costs exceed firing costs of production workers whereas firing costs exceed hiring costs of nonproduction workers

equilibrium welfare and government policy with quasi geometric discounting abstract we consider a representative agent equilibrium model where the consumer has quasi geometric discounting and cannot commit to future actions we restrict attention to a parametric class for preferences and technology and solve for time consistent competitive equilibria globally and explicitly we then characterize the welfare properties of competitive equilibria and compare them to that of a planning problem the planner is a consumer representative who without commitment but in a time consistent way maximizes his or her present value utility subject to resource constraints the competitive equilibrium results in strictly higher welfare than the planning problem whenever the discounting is not geometric journal of economic literature classification numbers e21 e61 e91

social security reform with self control preferences abstract this paper analyzes a fully funded social security system under the assumption that agents face temptation issues agents are required to save through individually managed personal security accounts without and with mandatory annuitization when the analysis is restricted to crra preferences our results are congruent with the literature in indicating that the complete elimination of social security is among the reform scenarios that maximize welfare however when self control preferences are introduced and as the intensity of self control becomes progressively more severe the social security elimination scenario loses ground very rapidly in fact in the case of relatively severe temptation the elimination of social security becomes the least desirable alternative under the light of the above findings any reform proposal regarding the social security system should consider departures from standard preferences to preference specifications suitable for dealing with preference reversals

a resource based theory of the firm knowledge versus opportunism this paper develops a resource based knowledge based theory of the firm its thesis is that the organizational mode through which individuals cooperate affects the knowledge they apply to business activity we focus on the polar cases of organization within a firm as compared to market contracting there will be a difference in the knowledge that is brought to bear and hence in joint productivity under the two options thus as compared to opportunism based transaction cost theory we advance a separate yet complementary answer to the question why do firms exist our aim is to develop an empirically relevant and complementary theory of why firms are formed a theory based on irreducible knowledge differences between individuals rather than the threat of purposeful cheating or withholding of information we assume limited cognitive abilities on the part of individuals bounded rationality and assume that opportunistic behavior will not occur the latter allows us to determine whether resource based

insurance self control and contract flexibility we study a competitive insurance market in which some consumers have too optimistic expectations regarding their future use of preventive measures when contracts are long term and inflexible such naive consumers would increase the costs of insurance for low risk consumers the competitive insurance market therefore offers flexible contracts that allow for switching between different tariffs sophisticated consumers choose a partial insurance tariff and remain low risks naive consumers choose the same tariff but later switch to full insurance and become high risks if there are sufficiently many naive consumers they pay a transfer to sophisticated consumers so that high risks subsidize low risks in contrast there are no such transfers when contracts are short term the model generates novel implications for the time frame of insurance contracts and insurance requirements

the limits of inference with theory a review of wolpin 2013 this essay reviews kenneth i wolpin s 2013 monograph the limits of inference without theory which arose from lectures he presented at the cowles foundation in 2010 in honor of tjalling koopmans while i readily agree with wolpin s basic premise that empirical work that eschews the role of economic theory faces unnecessary self imposed limits relative to empirical work that embraces and tries to test and improve economic theory it is important to be aware that the use of economic theory is not a panacea i point out that there are also serious limits to inference with theory 1 there may be no truly structural policy invariant parameters a key assumption underpinning the structural econometric approach that wolpin and the cowles foundation have championed 2 there is a curse of dimensionality that makes it very difficult for us to elucidate the detailed implications of economic theo ries which is necessary to empirically implement and test these theories 3 there is an identification problem that makes it impossible to decide between competing theories without imposing ad hoc auxiliary assumptions such as parametric functional form assumptions and 4 there is a problem of multiplicity and indeterminacy of equilibria that limits the predictive empirical content of many economic theories i conclude that though these are very challenging problems i agree with wolpin and the cowles foundation that economists have far more to gain by trying to incorporate economic theory into empirical work and test and improve our theories than by rejecting theory and presuming that all interesting economic issues can be answered by well designed controlled randomized experiments and assuming that difficult questions of causality and evaluation of alternative hypothetical policies can be resolved by simply allowing the data to speak for itself jel b41 c18

knowledge based approaches to the theory of the firm some critical comments it is argued that kogut and zander kogut b u zander 1992 knowledge of the firm combinative capabilities and the replication of technology organ sci 3 383 397 and conner conner k r 1991 a historical comparison of resource based theory and five schools of thought within industrial organization economics do we have a new theory of the firm j management 17 121 154 erred in the specific way in which they claimed that a distinct theory of the multi person firm can be constructed on the basis of a theory of organizational knowledge or from resource based insights it is not possible to tell very much of a story about why there should be firms in lieu of notions such as opportunism or moral hazard however properly interpreted knowledge based theories may help shed light on issues relating to the boundaries and internal organization of the firm

choice and procrastination author s o donoghue ted rabin matthew abstract recent models of procrastination due to self control problems assume that a procrastinator considers just one option and is unaware of her self control problems we develop a model where a person chooses from a menu of options and is partially aware of her self control problems this menu model replicates earlier results and generates new ones a person might forego completing an attractive option because she plans to complete a more attractive but never to be completed option hence providing a non procrastinator additional options can induce procrastination and a person may procrastinate worse pursuing important goals than unimportant ones

sex discrimination in restaurant hiring an audit study in an audit study of sex discrimination in hiring comparably matched pairs of men and women applied for jobs as waiters and waitresses at restaurants in philadelphia in high price restaurants where earnings are higher job applications from women had an estimated probability of receiving a job offer that was lower by about 0 4 and an estimated probability of receiving an interview that was lower by about 0 35 both estimated differentials are statistically significant additional evidence suggests that customer discrimination partly underlies the hiring discrimination

orchestrating impartiality the impact of blind auditions on female musicians a change in the audition procedures of symphony orchestras adoption of blind auditions with a screen to conceal the candidate s identity from the jury provides a test for sex biased hiring using data from actual auditions in an individual fixed effects framework we find that the screen increases the probability a woman will be advanced and hired although some of our estimates have large standard errors and there is one persistent effect in the opposite direction the weight of the evidence suggests that the blind audition procedure fostered impartiality in hiring and increased the proportion women in symphony orchestras

welfare dependence and self control an empirical analysis this paper investigates the behavioral and policy mechanisms that generate dependence on welfare programs a dynamic model with labor supply disincentives and state dependence in preferences is expanded to incorporate time inconsistency which induces addictive behavior due to problems of self commitment estimation is based on data from a welfare reform experiment which contains a unique policy feature that helps identify the time preference parameters various results indicate that the commitment problem is an important consideration in the design of policy around one fourth of the individuals are time inconsistent and neglecting time inconsistency will cause state dependence in preferences to be overestimated these individuals are more responsive to policy changes due to the presence of commitment related incentives time inconsistency reduces income and net tax contribution by at least 15 and 50 percent respectively an increase in welfare benets aggravates the commitment problem and reduces utility from a time consistent perspective certain dynamic policy interventions are more eective than static interventions in alleviating the commitment problem for instance a dynamic nonwork tax generates strong commitmentrelated work incentives and over half of time inconsistent individuals will voluntarily adopt it as a commitment device the implications of time inconsistency for other policy interventions such as earned income tax credit eitc and a prowork time limit are examined

discounting financial literacy time preferences and participation in financial education programs many policymakers and economists argue that financial literacy is key to financial well being but why do many individuals remain financially illiterate despite the benefits of being financially informed this paper presents results from a field study linking individual decisions to acquire financial information to a normally unobservable characteristic time preferences we elicited time preferences using incentivized choice experiments for all individuals to whom a financial education program was offered our results show that individuals who choose to acquire personal financial information have substantially higher discount factors than individuals who do not the results can be interpreted as non participants discount the benefits of being financially literate more

organizational capabilities and the economic history of the industrial enterprise in my book scale and scope 1990 i focused on the history of the modern industrial firm from the 1880s when such firms first appeared through world war ii i did so by comparing the fortunes of more than 600 enterprises the 200 largest industrial firms at three points in time world war i 1929 and world war ii in each of the three major industrial economies those of the united states britain and germany in this paper i first describe the similarities in the historical beginnings and continuing evolution of these enterprises and then outline my explanation for these similarities next i relate my explanation of these empirical regularities to four major economic theories relating to the firm the neoclassical the principal agent the transaction cost and the evolutionary finally i suggest the value of the transactions cost and evolutionary theories to historians and economists who are attempting to explain the beginnings and growth of modern industrial enterprises

on the compassion of time limited welfare programs supporters of recent welfare reforms argue that time limits and other eligibility restrictions serve recipients we present a simple model of agents with present biased preferences to investigate the theoretical validity of this claim we first identify four types of outcome that describe the behavior of a present biased agent in the absence of time limits we then show that the behavioral consequences of time limits are contingent on which outcome characterizes the agent s behavior in the absence of time limits we show that under some conditions the imposition of time limits may improve the wellbeing of welfare recipients evaluated both in terms of long run time consistent utility and the periodone self s utility this benefit of time limits may come either from allowing the welfare eligible to start working earlier than they otherwise would or contrary to the intent of the reforms from allowing them to postpone working d 2002 elsevier b v all rights reserved

leadership beliefs and coordination an explorative discussion although recent economics contributions represent important strides forward in the understanding of leadership behavior the cognitive and symbolic dimensions of the phenomenon have attracted virtually no interests from economists and game theorists i argue that an understanding of these dimensions may be founded on coordination games particularly to the extent that these illustrate interactive belief formation in this context leadership is defined as the taking of actions that coordinate the complementary actions of many people through the creation of belief conditions that at least substitute for common knowledge and where these actions characteristically consists of some act of communication directed at those being led the concept of common knowledge or its approximation by means of notions of common belief is argued to be particularly important to understanding leadership thus leaders may establish common knowledge conditions and assist the coordination of strategies in this way or make decisions in situations where coordination problems persist in spite of common knowledge acknowledgments

intellectual capital configurations and organizational capability an empirical examination of human resource subunits in the multinational enterprise building on the organizational capabilities literature and theories of the multinational enterprise this paper develops and tests a framework that examines the relationship between intellectual capital configurations and organizational capabilities in human resource hr subunits looking at 187 subunits from 20 mnes findings show that intellectual capital dimensions vary in their usefulness for generating sharing and implementing hr management practices in particular while certain resources may help in the development of one capability they may harm the development of another implications are that an organization s intellectual capital investments will differ depending on the desired capability

initiating private collective innovation the fragility of knowledge sharing incentives to innovate are a central element of innovation theory in the private investment model innovators privately fund innovation and then use intellectual property protection mechanisms to appropriate returns from these investments in the collective action model public subsidy funds public goods innovations characterized by non rivalry and non exclusivity in using these innovations recently these models have been compounded in the private collective innovation model where innovators privately fund public goods innovations private collective innovation is illustrated in the case of open source software development this paper contributes to the work on this model by investigating incentives that motivate innovators to share their knowledge in an initial situation before there is a community to support the innovation process we use game theory to predict knowledge sharing behavior in private collective innovation and test these predictions in a laboratory setting the results show that knowledge sharing is a coordination game with multiple equilibria reflecting the fragility of knowledge sharing between innovators with conflicting interests the experimental results demonstrate important asymmetries in the fragility of knowledge sharing and in some situations more knowledge sharing than theoretically predicted a behavioral analysis suggests that knowledge sharing in private collective innovation is not only affected by material incentives but also by social preferences such as fairness the results offer general insights into the relationship between incentives and knowledge sharing and contribute to a better understanding of the initiation of private collective innovation

retrieving and transferring embodied data implications for the management of interdependence within organizations this research helps to link theories of sticky information with organizational design and governance it suggests that information embodied in process material can allow downstream tasks to uncover information about upstream tasks it shows that downstream operators can use this information to negotiate interdependence problems with upstream operators data presented in this article begin to uncover when such information retrieval and exchange occurs and how managers can encourage it finally the article discusses implications for theories of operational design and governance

optimal policy instruments for externality producing durable goods under present bias abstract when consumers exhibit present bias the standard solution to market failures caused by externalities pigouvian pricing is suboptimal i investigate policies aimed at externalities for present biased consumers optimal policy includes an instrument to correct the externality and an instrument to correct the present bias either instrument can be an incentive based policy e g a tax on fuel economy or a command and control policy e g a fuel economy mandate under consumer heterogeneity a command and control policy may dominate an incentive based policy calibrated to the us automobile market simulation results suggest that the second best gasoline tax is 3 30 higher than marginal external damages the optimal price policy includes a gasoline tax set about equal to marginal external damages and a fuel economy tax that increases the price of an average non hybrid car by about 550 2200 relative to the price of an average hybrid car

is it socially efficient to impose job search requirements on unemployed benefit claimants with hyperbolic preferences dellavigna and paserman 2005 and paserman 2008 have shown that imposing job search requirements on sophisticated unemployed benefit claimants with hyperbolic time preferences is pareto improving in that it raises welfare for the unemployed by limiting harmful procrastination and for employees since the enhanced search boosts the job finding rate thereby reducing the contributions required for the funding of benefits this paper demonstrates that the range of pareto improvements is much reduced if the analysis takes into account the fact that benefit claimants may not comply with the requirements especially if the monitoring technology displays imperfections induced by caseworker discretion or measurement error

ramsey meets laibson in the neoclassical growth model the neoclassical growth model is modified to include a variable rate of time preference with no commitment ability and log utility the equilibrium features a constant effective rate of time preference and is observationally equivalent to the standard model the extended framework yields testable linkages between the extent of commitment ability and the rates of saving and growth the model also has welfare implications including the optimal design of institutions that facilitate household commitments steady state results are obtained for general concave utility functions and some properties of the transitional dynamics are characterized for isoelastic utility

transaction cost economics in real time this paper attempts to place the theq of the boundaries of thejirm within the context of the passage of time more precisely it resurrects and places in a modem frame some of the insights of the chsical and marshallian theories of organization the modem reinterpretation of those theories centers around the capabilities view of the jirm taken together with governance costs the capabilities ofjirm and market determine the boundaries of the jirm in the short run ovw time capabilities change as firms and markets learn which implies a kind of information or knowledge cost the cost of trandewing the firm s capability to the market w vice versa these dynamic governance costs are the costs of persuading negotiating and coordinating with and teaching others they arise in the face of change notably txchnological and organizational innovation in fit they are the costs of not having the capabilities you need when you need them dynamic transaction costs provide an explanation for vertical integration that is arguably more general than those dominant in the literature in the face of uncertainty and divwgent views ofthe future common ownership of multiple stages of production is a supwior institutional arrangement for coordinating systemic change asset specrfity is neither necessary nor suffient for this to be true dynamic governance costs may also affit internal organization it may sometimes be costly in 3 terms of persuasion negotiation and teaching to create within the firm capabilities readily available on the market indeed in cases in which systemic coordination is not 4 the issue the market may turn out to be the superior institution of coordination in e 2 genwal the capabilities view of the jirm suggests that we look atfim2 and market as alternative and sometimes overlapping institutions of learning 1 transaction costs in the long rzln and the short 9 x classical and neoclassical perspectives

determining consumers discount rates with field studies abstract because utility profits state transitions and discount rates are confounded in dynamic models discount rates are typically fixed for the purpose of identification the authors propose a strategy of identifying discount rates the identification rests on imputing the utility profits using decisions made in a context in which the future is inconsequential the objective function is concave and the decision space is continuous they then use these utilities profits to identify discount rates in contexts in which dynamics become material the authors exemplify this strategy using a field study in which cell phone users transitioned from a linear to a three part tariff pricing plan they find that the estimated discount rate corresponds to a weekly discount factor 90 lower than the value typically assumed in empirical research 995 when using a standard 995 discount factor they find that the price coefficient is underestimated by 16 moreover the predicted intertemporal substitution pat

revising commitments field evidence on the adjustment of prior choices the very poor in developing countries often make intertemporal choices that seem at odds with their individual self interest there are many possible reasons why this paper investigates several of these reasons with a lab in the field experiment in rural malawi involving large stakes it makes two contributions first it constructs a new dependent variable revisions of prior choices regarding the allocation of future income this allows us to directly examine intertemporal choice revision and its determinants in particular this dependent variable permits a novel test for the existence of self control problems it turns out revisions of money allocations toward the present are positively associated with measures of present bias from an earlier baseline survey as well as the randomly assigned closeness in time to the first possible date of money disbursement second the paper investigates other potential determinants of revision aside from self control problems it finds little evidence that revisions of money allocations toward the present are associated with spousal preferences for such revision household shocks or the financial sophistication of respondents

strategic ignorance as a self disciplining device we analyse the decision of an agent with time inconsistent preferences to consume a good that exerts an externality on future welfare the extent of the externality is initially unknown but may be learned via a costless sampling procedure we show that when the agent cannot commit to future consumption and learning decisions incomplete learning may occur on a markov perfect equilibrium path of the resulting intra personal game in such a case each agent s incarnation stops learning for some values of the posterior distribution of beliefs and acts under self restricted information this conduct is interpreted as strategic ignorance all equilibria featuring this property strictly pareto dominate the complete learning equilibrium for any posterior distribution of beliefs

exploiting naivete about self control in the credit market we develop a model of the credit market where competitive lenders oer long term contracts specifying a non linear schedule of possible repayment schedules to borrowers who may dier both in their taste for immediate gratication and their prior beliefs about that taste the equilibrium contract to a borrower with given beliefs is discontinuous it features an advantageous option involving fast repayment and a penalty for deviating and repaying later these predictions seem to resemble some salient features of many credit card and mortgage contracts for fully sophisticated borrowers the discontinuity acts as a commitment device and yields fast repayment but all other borrowers even those with an arbitrarily small amount of naivete end up delaying repayment despite the penalty and receive little benet from commitment furthermore because they believe they will repay early they underestimate the cost of credit and hence borrow too much non sophisticated borrowers cross subsidize sophisticated borrowers while sophisticated borrowers discipline rms by preventing very exploitative contracts we identify natural conditions under which the above results obtain even if

how social security and medicare affect retirement behavior in a world of incomplete markets this paper provides an empirical analysis of how the u s social security and medicare insurance system affect the labor supply of older males in the presence of incomplete markets for loans annuities and health insurance we estimate a detailed dynamic programming dp model of the joint labor supply and social security acceptance decision focusing on a sample of males in the low to middle income brackets whose only pension is social security the dp model delivers a rich set of predictions about the dynamics of retirement behavior and comparisons of actual vs predicted behavior show that the dp model is able to account for wide variety of phenomena observed in the data including the pronounced peaks in the distribution of retirement ages at 62 and 65 the ages of early and normal eligibility for social security benefits respectively we identify a significant fraction of health insurance constrained individuals who have no form of retiree health insurance other than medicare and who can only obtain fairly priced private health insurance via their employer s group health plan the combination of significant individual risk aversion and a long tailed pareto distribution of health care expenditures implies that there is a significant security value for these individuals to remain employed until they are eligible for medicare coverage at age 65 overall our model suggests that a number of heretofore puzzling aspects of retirement behavior can be viewed as artifacts of particular details of the social security rules whose incentive effects are especially strong for lower income individuals and those who do not have access to fairly priced loans annuities and health insurance

swimming upstream trends in the gender wage differential in the 1980s using michigan panel study of income dynamics data for 1979 and 1988 we analyze how a falling gender wage gap occurred despite changes in wage structure unfavorable to low wage workers the decrease is traced to gender specific factors which more than counterbalanced changes in measured and unmeasured prices working against women supply shifts net of demand were unfavorable for women generally and hurt high skilled more than middle and low skilled women by analyzing wages we find support for the notion of a gender twist in supply and demand having its largest negative effect on high skilled women
