Gender Differences in Lifelong Learning: An Empirical Analysis of the Impact of Marriage and Children

We use recent advances in the statistical analysis of Oaxaca–Blinder decompositions for non‐linear models to analyse the contribution of individual variables to total gender differences in training participation and duration. Results suggest that effects stemming from the intra‐household division of labour contribute significantly to gender differences, but that segregation of the labour market as well as differences in the access to training by tenure, age, occupation, profession and sectors are more important.     

DO WOMEN PAY MORE FOR CREDIT? EVIDENCE FROM ITALY

By using a unique and large data set on loan contracts between banks and microfirms, we find robust evidence that women in Italy pay more for credit than men, although we do not find any evidence that women borrowers are riskier than men. The male/female differential remains even after controlling for a large number of characteristics of the type of business, the borrower, and the structure of the credit market. The result is not driven by lack of credit history, nor by women using a different type of bank than men, since the same bank charges different rates to male and female borrowers.     

THE WELFARE GAINS OF FINANCIAL LIBERALIZATION: CAPITAL ACCUMULATION AND HETEROGENEITY

Research has shown that, absent individual heterogeneity and under complete markets, the welfare impact of financial openness is quantitatively limited. Not only are inequalities in wealth and labor productivity a feature of most societies, but also financial markets suffer from many well‐known frictions. This paper demonstrates that, when households face borrowing constraints and uninsurable idiosyncratic shocks to income, the welfare implications of financial liberalization are considerable. For instance, the average increase in welfare of a typical emerging market economy that switches from a closed capital market to perfect capital mobility is equivalent to a permanent increase in average consumption of roughly 5.4%. This is about 3.9 times more than the welfare gains of the same policy under a complete markets environment without any individual heterogeneity. We show that individual heterogeneity accounts for two thirds of this additional increase in the average welfare gain; market incompleteness accounts for the remaining third. In our calibration, the median household in capital‐scarce countries is in favor of international financial integration. However, if the pivotal voter is wealthy enough then such reform might not be implemented, since richer households have a vested interest in capital market closedness.     

LACK OF COMMITMENT AND THE LEVEL OF DEBT

The tendency of countries to accumulate public debt has been rationalized in models of political disagreement and lack of commitment. We analyze in a benchmark model how the evolution of public debt is affected by lack of commitment per se. While commitment introduces indeterminacy in the level of debt, lack of commitment creates incentives for debt to converge to specific levels. One of the levels that debt often converges to implies no debt accumulation at all. In a simple example we prove analytically that debt converges to zero, and we analyze numerically more complex models. We also show in an imperfect credibility setting that a small deviation from full‐commitment is enough to obtain these results.     

Returns to Foreign Language Skills of Immigrants in Spain

This study examines the returns to foreign language skills of immigrants in the Spanish labor market. Measurement error and endogeneity issues are addressed by deriving a set of novel instruments for foreign language proficiency through a measure of linguistic dissimilarity. Using cross‐sectional data from the 2007 National Immigrant Survey of Spain (NISS), returns to language skills are estimated separately for English, German, and French proficiency. Foreign language proficiency produces high returns, which appear to be mediated through the channel of occupational choice. The results are discussed against the background of a severe foreign language skills shortage in the Spanish economy. Immigrants may deal as a supplier of foreign language proficiency in the short run.

Generalized likelihood-ratio test of the number of components in finite mixture models

The number of components is an important feature in finite mixture models. Because of the irregularity of the parameter space, the log-likelihood-ratio statistic does not have a chi-square limit distribution. It is very difficult to find a test with a specified significance level, and this is especially true for testing k — 1 versus k components. Most of the existing work has concentrated on finding a comparable approximation to the limit distribution of the log-likelihood-ratio statistic. In this paper, we use a statistic similar to the usual log likelihood ratio, but its null distribution is asymptotically normal. A simulation study indicates that the method has good power at detecting extra components. We also discuss how to improve the power of the test, and some simulations are performed.
