A rational-expectations equilibrium with positive demand for financial information does exist under fully revealing asset price-contrary to a wide-held conjecture. Generalizing the common additive signal-return model with CARA utility to the family of distributions with moment generating...

Tracking individual workers across employers and industries after Brazil's trade liberalization in the 1990's shows that foreign import penetration and tariff reductions trigger worker displacements but that neither comparative-advantage industries nor exporters absorb displaced workers for...

Using data for German and Swedish multinational enterprises (MNEs), this paper assesses international employment patterns. It analyzes determinants of location choice and the degree of substitutability of labor across locations. Countries with highly skilled labor forces attract German MNEs, but...

Add an opening stage of signal acquisition to a canonical portfolio choice model and let investors have rational expectations about the ensuing Walrasian equilibrium. The expected marginal utility of a signal (its action value) falls in the number of signals and turns strictly negative at a...

We employ a comprehensive linked employer-employee data set for Brazil to analyze wage determinants and compare results to Abowd, Kramarz, Margolis and Troske (2001) for French and U.S. manufacturing. While returns to human capital variables in Brazilian manufacturing exceed those of the other...

While neoclassical theory emphasizes the impact of trade on wage inequality between occupations and sectors, more recent theories of firm heterogeneity point to the impact of trade on wage dispersion within occupations and sectors. Using linked employer-employee data for Brazil, we show that...

Tracking individual workers across jobs after Brazil's trade liberalization in the 1990s shows that tariff cuts trigger worker displacements, but neither exporters nor comparative-advantage sectors absorb trade-displaced labor. On the contrary, exporters separate from significantly more and hire...

This paper proposes a proximity-concentration tradeoff in product space as a determinant of horizontal foreign direct investment (FDI). Firms that enter a foreign market by exporting are able to capture consumer surplus from introducing a differentiated product with characteristics that the...
