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....

A quantitative framework of firm dynamics is developed where the size of the informal sector is determined by financial constraints and the burden of taxation. Improving access to credit for formal sector firms increases aggregate TFP and output while reducing the size of the informal sector....

Commodity prices are an important driver of fiscal policy and the business cycle in many developing economies. We analyze a dynamic stochastic small-open-economy model of sovereign default, featuring endogenous fiscal policy and stochastic commodity revenues. The model accounts for a positive...

I develop an asymmetric two-country incomplete markets model in which economies trade final consumption goods and inputs. The purchases of imported inputs from the firms of one of the economies (the emerging) to the firms of the other economy (the advanced) are subject to a foreign currency...

The global financial crisis of late 2008 could not have provided more convincing evidence that price stability is not a sufficient condition for financial stability. In order to attain both, central banks must develop macroprudential instruments in order to prevent the occurrence of systemic...

Optimal tax theory has diffculty rationalizing high marginal tax rates at the upper end of the income distribution. In this paper, I construct a model of optimal income taxation in which agents' preferences are interdependent. I derive a simple expression for optimal taxes that accommodates...

In order to create an environment of low and stable inflation in Mexico it has been necessary to generate a framework for the conduction of monetary policy focused on price stability along with fiscal discipline. This paper describes some structural achievements to control inflation that have...

We document the existence of asymmetric price transmission in Mexico for a wide variety of food and non-food products, in terms of magnitude and speed, for two segments of the supply chain: i) Producer (producer-wholesale) and ii) Consumer (wholesale-retail). We find that asymmetric price...

As a consequence of the international environment, the currencies of many emerging market economies have experienced important depreciations in a context of high volatility in financial markets. The Mexican peso has not been the exception to the above situation. In this setting, the exchange...
