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...

Based on a classical financial market model different model variants known from the literature are discussed and analyzed, each focussing on modeling financial markets as a nonlinear dynamic system by introducing the formation of (heterogeneous) beliefs about future asset prices into the model...

The consumption capital asset pricing model is the standard economic model used to capture stock market behavior. However, empirical tests have pointed out to its inability to account quantitatively for the high average rate of return and volatility of stocks over time for plausible parameter...

Conventional wisdom says that economic surplus is created when the cost of litigation is foregone in favor of settlement, a theory flowing from the Coase Theorem. The cost-benefit analysis weighs settlement against the expected value of litigation net of transaction cost. This calculus yields...

From a financial economic perspective, the governing condition of a meritorious civil action is the uncertainty of outcome. Expectation and outcome deviate, and the spread is the measure of uncertainty (or variance). During litigation each party has an option to settle or select trial. The...
