Today’s global world is characterized not only by a high volume of international trade and foreign investment relative to national income, but also by a changed composition of that trade towards a greater fraction of trade in inputs and capital goods and outsourcing of production.. Emphasized...

Using a comprehensive international trade data set we investigate empirical regularities (known as Zipf’s Law or the rank-size rule) for the distribution of the interaction between countries as measured by revealed comparative advantage. Using the recently developed estimator by Gabaix and...

We develop a Heckscher-Ohlin-Ramsey model, combining dual techniques with classic geometric techniques from trade theory. This framework is used to explore the long-run general equilibrium effects of regional integration (preferential trade agreements). Emphasis is placed on positive mechanics...

Most of the large tariff reductions achieved in multilateral trade negotiations have involved tariff-cutting formulas such as the "Swiss" formula. However, wide variations in initial tariff rates between active participants call for new approaches under the Doha Development Agenda. This paper...

In this paper it is argued that occupational and organizational codes maximize the correspondence between activities and easily observable characteristics at the time of their development. Over time the codes become less relevant, leading to the false impression that the segregation of...

We present a structural framework for the evaluation of public policies intended to increase job search intensity. Most of the literature defines search intensity as a scalar that influences the arrival rate of job offers; here we treat it as the number of job applications that workers send out....

This meta-analytical review of empirical studies of the impact of schooling on entrepreneurship selection and performance in developing economies looks at variations in impact across specific characteristics of the studies. A marginal year of schooling in developing economies raises enterprise...

We present an experimental test of a shirking model where monitoring intensity is endogenous and effort a continuous variable. Wage level, monitoring intensity and consequently the desired enforceable effort level are jointly determined by the maximization problem of the firm. As a result,...

This paper proposes a simple social network model of occupational segregation, generated by the existence of inbreeding bias among individuals of the same social group. If network referrals are important in getting a job, then expected inbreeding bias in the social structure results in different...

Organization differ in the degree to which they differentiate employees by ability. We analyse how the effect of differentiation on employee morale may explain this variation. By comparing employees using ordinary talk, a manager boosts the self-image of some, but hurts that of others. Whether...
