This paper evaluates the international integration hypothesis, that is, that risk-adjusted anticipated returns are identical, even when financial instruments are traded in different countries. Under time-varying conditional volatility, this hypothesis is tested by verifying the equality between...

We test whether dynamic, stochastic, general equilibrium artificial economies associated with several labor market institutions provide an adequate characterization of aggregate employment volatility and dynamics. Our test is robust to possible misspecifications about the information set used by...

We study the development of a duopoly industry -evolution of firm capacities and competitive behavior- in a continuous-time real-options model of capacity investment. Our methodology allows the evaluation of investment options and exercise rules in a strategic setup. In the initial industry...

We attempt to answer the following questions: What are the revaluation effects and the impact on performance, volatility, and return correlation from stock market liberalization in emerging markets? These questions have been studied extensively at the market-level but not at the firm level. Our...
