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

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

The macroeconomic model of an irregular economy proposed by B. Contini, F. Cugno and M. Galeotti (1984) is extended by increasing the number of state variables and thus the dimension of the phase space for the relative dynamical system.By showing, through standard Liapunov methods, the non existence of closed non trivial orbits, the global attractivity of the equilibrium set is proved, under suitable boundary conditions.Control policies leading the economy to a desired equilibrium state are seen to be feasible, and central instruments which appear to be effective in this respect are briefly discussed.
Riassunto Il lavoro estende un modello macroeconomico dell'economia irregolare che è stato proposto da B. Contini, F. Cugno e M. Galeotti nel 1984.Come nello schema originario la dimensione di ciascun settore economico (quello regolare e quello irregolare) dipende dall'andamento dei costi ad esso relativi, mentre il tasso di inflazione è legato ai prezzi ed alle quote dei due diversi settori.Noi non trattiamo, tuttavia, il differenziale tra i tassi di crescita della produttività,k, come una grandezza costante, e scriviamo, invece, una nuova equazione differenziale che ne descrive la dinamica.In questo modo si ottiene uno spazio delle fasi di dimensione tre che è stratificato da varietà invarianti di dimensione due. Ciascuna di queste varietà contiene esattamente un punto di equilibrio, che si prova essere un attrattore globale, sotto opportune condizioni al bordo.Dimostriamo, infine, che nell'ambito del nostro modello è formalemente possibile controllare il settore irregolare; questo ci porta al problema economico di quali politiche centrali siano atte a far conseguire un obbiettivo fissato relativamente alla dimensione della attività regolari ed irregolari in cui si articola il sistema.相似文献

In questa nota si propone una estensione del modello dinamico di economia monetaria di puro scambio sviluppato da D. Friedman in un lavoro recente [5]. Lo schema analitico mantiene il carattere non deterministico e non tâtonnement introdotto da S. Smale nello studio di processi transattivi [9]. Ammettendo che la merce usata nel sistema come moneta sia richiesta dagli agenti non solo sulla base delle sue caratteristiche fisiche, ma anche a partire dal ruolo istituzionale assolto, si prova che il processo economico converge ad una varietà di configurazioni finali che è strettamente più ampia dell'insieme degli equilibri walrasiani. 相似文献

Improving the outcomes of youth with medical limitations: Evidence from the National Job Corps Study
Heinrich Hock Dara Lee Luca Tim Kautz David Stapleton 《Journal of Economics & Management Strategy》2023,32(3):636-656
Improving work outcomes for youth with disabilities and reducing their reliance on disability benefits are important policy priorities, but existing interventions have shown limited promise. We provide new evidence to inform this discussion by re-analyzing data from the 1990s National Job Corps Study, a randomized field experiment conducted nationwide in the United States. Job Corps, which provides comprehensive training to economically disadvantaged youth, is the nation's largest youth program outside of the school system. We examine youth who had medical limitations when they enrolled in the experiment, a group that has not previously been studied. During the 4 years after random assignment, participation in Job Corps increased the earnings of youth with medical limitations—substantially more so than for youth without medical limitations—and additionally reduced their receipt of disability cash benefits. Interventions designed specifically for such youth have not typically demonstrated reductions in benefit receipt. Hence, our re-analysis of the field experiment suggests that Job Corps could be a promising model for helping some youth with disabilities gain a foothold in the labor market and achieve greater self-sufficiency. 相似文献

In this paper we construct a large Bayesian Vector Autoregressive model (BVAR) for the Euro area that captures the complex dynamic inter-relationships between the main components of the Harmonized Index of Consumer Prices (HICP) and their determinants. The model generates accurate conditional and unconditional forecasts in real-time. We find a significant pass-through effect of oil-price shocks on core inflation and a strong Phillips curve during the Great Recession. 相似文献
