We present an analytically tractable general equilibrium business cycle model that features micro-level investment lumpiness. We prove an exact irrelevance proposition which provides sufficient conditions on preferences, technology, and the fixed cost distribution such that any positive upper...

This paper introduces sectorial heterogeneity in TFPs in a growth model to generate new insights on trade, sectorial reallocation, and economic growth. The rate of overall economic growth in this model is a simple average of sectorial growth in a closed economy, but will depend on trade...

We propose a novel generalized recursive smooth ambiguity model which allows a three-way separation among risk aversion, ambiguity aversion, and intertemporal substitution. We apply this utility to a consumption-based asset pricing model in which consumption and dividends follow hidden Markov...

This dissertation asks whether frequency misspecification of a New Keynesian model results in temporal aggregation bias of the Calvo parameter. First, when a New Keynesian model is estimated at a quarterly frequency while the true data generating process is the same but at a monthly...

We propose a Bayesian framework in which the uncertainty about the half-life of deviations from purchasing power parity can be quantified. Based on the responses to a survey study, we propose a prior probability distribution for the half-life under the recent float intended to capture widely...
