The preponderance of minimal second language acquisition by immigrants worldwide is striking. This paper proposes a theoretical model, which analyzes the underlying forces that contribute to this outcome of minimal secondary language acquisition by immigrants in such diverse immigrant-receiving...

The paper analyzes the contemporary organizational restructuring of production and work within firms. We emphasize the shift from a "Tayloristic" organization of work (characterized by significant specialization by tasks) to a "holistic" organization (featuring job rotation, integration of tasks...

Macroeconomic shocks and labour-market institutions jointly determine employment growth and economic performance. The effect of shocks depends on the nature of these intitutions and the effect of institutional change depends on the macroeconomic environment. It follows that a given set of...

This paper demonstrates gender differences in risk aversion and ambiguity aversion. It also contributes to a growing literature relating economic preference parameters to psychological measures by asking whether variations in preference parameters among persons, and in particular across genders,...

In contrast to the very large literature on skill-biased technical change among workers, there is hardly any work on the importance of skills for the entrepreneurs who employ those workers, and in particular on their evolution over time. This paper proposes a simple theory of skill-biased change...

We combine two empirical observations in a general equilibrium occupational choice model. The first is that entrepreneurs have more control than employees over the employment of and accruals from assets, such as human capital. The second observation is that entrepreneurs enjoy higher returns to...

We model individual careers in sports and games from initial entry to eventual exit or success as a discrete-choice, finite-horizon optimization problem. We apply this model to the international game of chess and study cross-country differences in the relative success of players. While we find...

As credit and insurance markets are imperfect, and given that intra-family transfers, and the way a child uses her time outside school hours, are private information, the second-best policy makes school enrollment compulsory, forces overt child labour below its efficient level (if positive), and...

Immigrant workers and their labor force participation in host countries have received critical attention in all concerned disciplines, principally owing to its strong implications for well-being of natives. The ageing population in many rich countries and several related and unrelated issues...

We propose occupational decisions of heterogeneous individuals as an alternative mechanism of explaining the distribution of firm productivities emphasized by empirical studies. Thus, we integrate the frameworks of Melitz (2003), and of Manasse and Turrini (2001) that establish the theoretical...
