In this paper we study the causal effect of a large expansion of publicly provided health insurance on school enrollment rates and on children's academic performance using the case of Mexico. Access to free health insurance could improve education outcomes directly by making household members...

This paper studies the effects of remittances from the U.S. on child labor and school attendance in recipient Mexican households. We identify these effects using the impact of the 2008-2009 U.S. recession on remittance receipts. The methodology employed is a differences-in-differences strategy...

A stumbling block in the modelling of competitive markets with commodity and price spaces of infinite dimensions, arises from having positive cones with an empty interior. This issue precludes the use of tools of differential analysis, ranging from the definition of a derivative, to the use of...

We study the problem of finding necessary and sufficient conditions that guarantee global uniqueness of equilibria in a pure exchange economy. We show that for every economy to have a unique equilibrium it is necessary and sufficient that (i) there are no critical economies and (ii) a compact...
