We develop a theory of optimal stopping problems under ambiguity in continuous time. Using results from (backward) stochastic calculus, we characterize the value function as the smallest (nonlinear) supermartingale dominating the payoff process. For Markovian models, we derive an adjusted...

This dissertation consists of three chapters relating to identification and inference in dynamic microeconometric models including dynamic discrete games with many players, dynamic games with discrete and continuous choices, and semiparametric binary choice and duration panel data...

The rapid growth in demand and supply of sophisticated data mining and analytical decision tools calls for research to understand the value of learning, as well as how learning interacts with firms’ day-to-day marketing strategies.In this paper, we consider a market in which the firm can...

We develop a dynamic capital valuation model in which each farm can take an action with farm-varying cost to increase the probability of not contracting a disease. In the presence of infection externalities, circumstances are identified under which multiple equilibria exist and where the one...

En la cub: "Revised version: September 2015" ; En este trabajo investigamos la interacción entre estabilidad de precios y sostenibilidad de la deuda soberana en el marco de un modelo de pequeña economía abierta, en la cual el gobierno emite deuda nominal y elige la política fi scal y...

Incluye un apéndice en línea ; Los modelos de mercados incompletos con agentes heterogéneos están cobrando especial relevancia en los análisis de políticas económicas. En este documento proponemos una nueva metodología para resolver problemas de políticas dinámicas óptimas, tanto...

The principal-agent model can be more often employed as a conceptual framework for studies in the fields of economics and finance. This article presents real examples in which this theoretical model fits well. It is admitted that the complexity of this type of model can be a barrier to its use....

The probability that actors in economic relationships break rules increases with the profits they thus expect to earn. It decreases with the probability and level of short- and long-term losses resulting from disclosure. It also decreases with the level of social context factors and intrinsic...

We analyze several exotic options of American style in a multiple prior setting and study the optimal exercise strategy from the perspective of an ambiguity averse buyer in a discrete time model of Cox-Ross-Rubinstein style. The multiple prior model relaxes the assumption of a known distribution...
