Firm dynamics, investment, and debt portfolio: balance sheet effects of the Mexican crisis of 1994

We build a partial equilibrium model of firm dynamics under exchange rate uncertainty. Firms face idiosyncratic productivity shocks and observe the current level of the real exchange rate each period. Given their current level of capital stock, firms make their export decisions and choose how much to invest. Investment is financed through one period loans from foreign lenders. The interest rate charged by each lender is set to satisfy an expected zero-profit condition. The model delivers a distribution of firms over productivity, capital stocks and debt portfolios, as well as an exit rule. We calibrate the model using data from a panel of Mexican firms, from 1989 to 2000, and analyze the effect of the 1994 crisis on these variables. As a result of the real exchange rate depreciation, the model predicts: (i) an increase in the debt burden, (ii) an increase in exports and (iii) a large decline in investment. These real effects are consistent with the evidence for the Mexican crisis.
