Taux de marge et structure financière

This paper shows that the firm markup, capital and the expected rate of capacity utilisation depend on its financial structure (debt/equity ratio) when irreversible investment faces uncertainty and when there is asymmetric information between the entrepreneur and lenders. Mark-up depends positively on the probability of excess demand and therefore negatively on capital. Capital increases with the markup/cost of capital ratio. A finance constraint on capital increases the probability of excess demand. Simultaneously it increases the mark-up which lower demand, so that it limits the rise of the probability of excess demand.
