The national origin of an individual's human capital is a crucial determinant of its value. Education and labor market experience acquired abroad are significantly less valued than human capital obtained domestically. This difference can fully explain the earnings disadvantage of immigrants relative to comparable natives in Israel. Variation in the return to foreign schooling across origin countries may reflect differences in its quality and compatibility with the host labor market. The return to foreign experience is generally insignificant. Acquiring additional education following immigration appears to confer a compound benefit by raising the return to education acquired abroad.

Using Canadian data, I investigate the relationships among sectoral mobility, unemployment spells, and total unemployment. Recent North American evidence suggests that incidence shifts toward high wage-high tenure workers may increase equilibrium unemployment through decreasing sectoral mobility and increasing spells. Using a multiple spell transition model, I find that, while shifts toward such workers may have these effects, composition changes that lead to higher mobility can also increase unemployment. A further investigation into the relative roles of mobility and spell lengths in driving total unemployment indicates that the influence of the former is comparatively small.

This study tests the efficiency wage hypothesis by estimating wage and quit equations with data from the Employment Opportunity Pilot Project survey of firms. An efficiency wage model is derived that predicts effects of turnover costs and unemployment on wages as functions of first and second derivatives from the quit equation. The model is tested by examining the relationships between the coefficients in the wage and quit equations; the results are generally favorable to efficiency wage theory. Other important findings are that firm characteristics raising workers' productivity tend to raise wages and that a rise in turnover costs reduces quits.

This paper explores the differential nature of labor-supply decisions regarding weeks of work per year and hours of work per week among female household heads. A model of labor supply that separates the weeks/hours decision is presented and estimated, allowing for simultaneity in the weeks/hours decision, as well as for the presence of either fixed costs or weeks and hours constraints. The results indicate that not only are weeks and hours decisions separate from the labormarket participation decision, but they are also quite different from each other, although they appear to be simultaneously determined.

According to Lazear, workers and firms enter into long-term implicit contracts that discourage shirking and malfeasance by shifting compensation to the end of the contract. Such "delayed payment" contracts are less likely to occur in jobs in which it is comparatively simple to monitor worker effort. This paper uses data from the National Longitudinal Survey and the Dictionary of Occupational Titles to test that hypothesis. In particular, it tests whether jobs that involve repetitive tasks tend to be characterized by an absence of pensions, mandatory retirement, long job tenures, and high wages for older workers.

We study the connection between the global liquidity crisis and the severe credit crunch experienced by finance companies (SOFOLES) in Mexico using firm-level data between 2001 and 2011. Our results provide supporting evidence that, as a result of the liquidity shock, SOFOLES faced severely restricted access to their main funding sources (commercial bank loans, loans from other organizations, and public debt markets). After controlling for the potential endogeneity of their funding, we find that the liquidity shock explains 64 percent of SOFOLES’ credit contraction during the recent financial crisis (2008–2009). We use our estimates to disentangle supply from demand factors as determinants of the credit contraction. After controlling for the large decline in loan demand during the financial crisis, our findings suggest that supply factors (such as nonperforming loans and lower liquidity buffers) also played a significant role. Finally, we find that financial deregulation implemented in 2006 may have amplified the effects of the global liquidity shock.

Value-at-risk methods which employ a linear (“delta only”) approximation to the relation between instrument values and the underlying risk factors are unlikely to be robust when applied to portfolios containing non-linear contracts such as options. The most widely used alternative to the delta-only approach involves revaluing each contract for a large number of simulated values of the underlying factors. In this paper we explore an alternative approach which uses a quadratic approximation to the relation between asset values and the risk factors. This method (i) is likely to be better adapted than the linear method to the problem of assessing risk in portfolios containing non-linear assets, (ii) is less computationally intensive than simulation using full-revaluation and (iii) in common with the delta-only method, operates at the level of portfolio characteristics (deltas and gammas) rather than individual instruments.

Rational models claim “trading to learn” explains widespread excessive speculative trading and challenge behavioral explanations of excessive trading. We argue rational learning models do not explain speculative trading by studying day traders in Taiwan. Consistent with previous studies of learning, unprofitable day traders are more likely than profitable traders to quit. Consistent with models of overconfidence and biased learning (but not with rational learning), the aggregate performance of day traders is negative; 74% of day trading volume is generated by traders with a history of losses; and 97% of day traders are likely to lose money in future day trading.
