This article develops a search model of the labor market with matching, bargaining, and employers' taste discrimination in which—under necessary but standard distributional assumption—it is possible to separately identify gender discrimination and unobserved productivity differences. The equilibrium shows that both prejudiced and unprejudiced employers wage discriminate. Maximum likelihood estimates on CPS data indicate that half of the employers are prejudiced, average female productivity is 6.5% lower, and two‐third of the gender earning differential may be explained by prejudice. An affirmative action policy is implemented resulting in a redistribution of welfare from men to women at no cost for employers' welfare. 相似文献

Reciprocal Trade Agreements in Gravity Models: A Meta-Analysis 总被引:1,自引:0,他引:1
The gravity model is a workhorse tool applicable in a wide range of empirical fields. It is regularly used to estimate the impact of reciprocal trade agreements (RTAs) on trade flows between partners. The studies report very different estimates since there is a significant difference in datasets, sample sizes, and independent variables. This paper combines, explains, and summarizes a large number of results using a meta-analysis approach. We provide pooled estimates, obtained from fixed and random effects models of the RTAs' effect size on bilateral trade: the hypothesis that there is no effect of RTAs on trade is robustly rejected at standard significance levels. The information collected on each estimate allows us to test the sensitivity of the results to alternative specifications and differences in the control variables considered, as well as the impact of the publication selection process. 相似文献

This paper analyzes the development of strong and weak ties of social capital between a start‐up and its main customers and its impact on the growth of the start‐up's economic and innovative task performance outcomes. Results confirm that there are different configurations of social capital able to influence the start‐up's performance growth during its life cycle, which are contingent on the selected measures of task performance outcomes. Our findings can offer some interesting reflections in the field of social capital, entrepreneurship, and performance research, raising critical strategic implications for start‐ups in terms of opportunities, resources, and governance. 相似文献

Summary. We ask whether communication can directly substitute for memory in dynastic repeated games in which short lived individuals care about the utility of their offspring who replace them in an infinitely repeated game. Each individual is unable to observe what happens before his entry in the game. Past information is therefore conveyed from one cohort to the next by means of communication.When communication is costless and messages are sent simultaneously, communication mechanisms or protocols exist that sustain the same set of equilibrium payoffs as in the standard repeated game. When communication is costless but sequential, the incentives to whitewash the unobservable past history of play become pervasive. These incentives to whitewash can only be countered if some player serves as a neutral historian who verifies the truthfulness of others reports while remaining indifferent in the process. By contrast, when communication is sequential and (lexicographically) costly, all protocols admit only equilibria that sustain stage Nash equilibrium payoffs.We also analyze a centralized communication protocol in which history leaves a footprint that can only hidden by the current cohort by a unanimous coverup. We show that in this case the set of payoffs that are sustainable in equilibrium coincides with the weakly renegotiation proof payoffs of the standard repeated game.Received: 30 September 2002, Revised: 5 August 2003, JEL Classification Numbers:

Euro-deposit futures play a relevant role among the derivative products traded in official markets. As opposed to most futures contracts, the underlying instrument is not represented by a traded asset but by a linear transformation of an interest rate, the Libor. The options written on Euro-deposit futures that are traded at the London International Financial Futures & Options Exchange (LIFFE) are subject to daily marking to market, as the underlying futures; thus, they are called futures-style options or pure futures options. These options are often priced with the Black (1976) formula, whose use entails several shortcomings. A more realistic alternative is represented by the univariate Cox, Ingersoll and Ross (1985) model. The closed-form solutions for the prices of Euro-deposit futures and futures-style options on Euro-deposit futures obtained in the CIR model are two major original contributions presented in this paper. Other original contributions involve the determination of the relation between futures rates and forward rates and the derivation of the equivalent portfolio for the hedging of futures-style options on Euro-deposit futures. 相似文献

The social opportunity cost of consumption (SOCC) for an economy is the rate at which current consumption can be traded for consumption in the future. The SOCC is an important determinant of the socially optimal levels of investment and the current account surplus and should be an input into the framing of government economic policy. Using overseas interest rates, the SOCC for Australia is calculated in this article. The calculated series is fairly constant for the 1960s and then has a pronounced cyclical pattern from the late 1960s to 1988–89. The average value of the SOCC for Australia is about four per cent. 相似文献

We tackle the issue of optimal dynamic taxation of capital income in an economy with disconnection as in Weil (J Public Econ 38:183–198, 1989), generated by migration and intra-family altruism. We show that, when the government aims at correcting such a disconnection using time-varying weights in the social welfare function, then there is room for nonzero capital income taxation, both in the short and in the long run. 相似文献

We analyze social dynamics in a continuous population where randomly matched individuals have to choose between two pure strategies
only ('cooperate' (C) and 'not cooperate' (NC)). Individual payoffs associated with the possible outcomes of each interaction
may differ across groups, depending on the specific social and cultural context to which each agent belongs. In particular,
it is assumed that three sub-populations are initially present, 'framing' the game according to the prisoner's dilemma (PD),
assurance game (AG) and other regarding (OR) payoff configurations, respectively. In other words, we assume that common knowledge
about the payoffs of the game is 'culturally-specific'. In this context, we examine both the adoption process of strategies
C and NC within each sub-population and the diffusion process of 'types' (PD, AG and OR) within the overall community. On
the basis of an evolutionary game-theoretic approach, the paper focuses on the problem of coexistence of PD, AG and OR groups as well as of 'nice' (C) and 'mean' (NC) strategies. We show that coexistence between C and NC is
possible in the heterogeneous community under examination, even if it is ruled out in homogeneous communities where only one
of the three types is present.

In a beauty contest framework, public authorities decide the accuracy of public information evaluating how it affects individual actions and private information acquisition. More precise public information increases welfare whenever its marginal cost does not exceed that of private information. 相似文献
