We develop a model in which delinquents compete with each other in criminal activities but may benefit from being friends with other criminals by learning and acquiring proper know-how on the crime business. By taking the social network connecting agents as given, we study the subgame perfect...

We develop a model in which non-white individuals are defined with respect to their social environment (family, friends, neighbors) and their attachments to their culture of origin (religion, language), and in which jobs are mainly found through social networks. We find that, depending on how...

This paper considers a small open economy with an input-output industrial structure that creates vertical linkages and multiple equilibria. An imperfect labor market is introduced by assuming unionized labor. It is shown that a deregulation of the labor market may trigger a large discontinuous...

The paper demonstrates how trade between developing countries can cause the divergence of long-run growth among these countries. The model describes two symmetric countries trading with each other and the industrial rest of the world. Bilateral trade occurs at any moment if the countries have...

This paper presents a dynamic general equilibrium model of trade between two advanced countries in which both innovation and skilled acquisition rates are endogenously determined. The model offers a North-North (as opposed to a North-South) trade explanation for increasing relative wage...

Unlike previous analyses, we consider (i) that IT may affect productivity growth both directly and indirectly, through human capital interactions, and (ii) possible externalities in the use of IT. Examining, hypothetically, the statistical consequences of erroneously disregarding (i) and (ii) we...

Results from empirical studies of firm behavior are synthesized into, a theory of the firm as a competent team. I demonstrate the existence of a tacit organizational competence exercising a leverage on the productivities of all other factors through selecting and allocating competent people,...

This paper raises several issues concerning productivity analysis. An attempt is made to demonstrate the usefulness of a micro-based approach to productivity analysis which challenges some basic assumptions of conventional analyses based on aggregate production functions. With the help of a...
