This paper estimates a hidden Markov model where inflation is determined by government deficits financed through money creation and by expectations dynamics. The baseline model, proposed by Sargent et al. (2009) is able to distinguish between causes and remedies of hyperinflation, such as...

We develop a quantitative theoretical model of firm dynamics to analyze key determinants of the elasticity of exports with respect to the exchange rate. The model incorporates mechanisms that determine the firms? capacity to react when the profitability of exports change due to fluctuations in...

We construct a framework of firm dynamics to evaluate the impact of the enforcement of contracts between final goods producers and their intermediate goods suppliers on firm growth, technology accumulation, and aggregate productivity. We build upon the static contracts model of Acemoglu et al....
