We propose a theory of trade in which comparative advantages reveal themselves gradually over the path of development. Following the Ricardian tradition, countries specialise and export the set of goods they are able to produce at relatively lower cost given their exogenous initial endowments....

We provide evidence showing that the degree of diversification of import sources of finely disaggregated commodities rises monotonically along the growth path. This result is robust to different measures of import diversification and the inclusion of a large set of additional control variables....

We study the interplay of probabilistic sophistication, second order stochastic dominance, and uncertainty aversion, three fundamental notions in choice under uncertainty. In particular, our main result, Theorem 2, characterizes uncertainty averse preferences that satisfy second order stochastic...

We study unique and globally attracting solutions of a general nonlinear equation that has as special cases some recursive equations widely used in Economics.

We study the equivalence between the MB-set and the core in the general context of games with a measurable space of players. In the first part of the paper, we study the problem without imposing any restriction on the class of games we consider. In the second part, we apply our findings to...

This paper studies the link between migration, remittances and productive assets accumulation for a panel of poor rural households in Mexico over the period 1997-2006. In a context of financial markets imperfections, migration may act as a substitute for imperfect credit and insurance provision...

We propose an occupational choice model in which the quality of the state bureaucracy influences aggregate output and the level of entrepreneurial activity through its participation in the labour market. Skilled agents differ in terms of their public service motivation: if agents with low public...

We study the cores of non-atomic market games, a class of transferable utility co- operative games introduced by Aumann and Shapley [2], and, more in general, of those games that admit a na-continuous and concave extension to the set of ideal coalitions, studied by Einy, Moreno, and Shitovitz...

A definition of set-wise differentiability for set functions is given through refining the partitions of sets. Such a construction is closely related to the one proposed by Rosenmuller (1977) as well as that studied by Epstein (1999) and Epstein and Marinacci (2001). We present several classes...

Concavity and supermodularity are in general independent properties. A class of functionals defined on a lattice cone of a Riesz space has the Choquet property when it is the case that its members are concave whenever they are supermodular. We show that for some important Riesz spaces both the...
