In this paper, we assess the impact of farm size on the production cost and evaluate the marginal costs and margins by taking into account that input prices may change with the scale of production. By using French data at the hog farm level, we estimate a system of equations including feed price...

In this paper, we set up a simple model that explains the relation between low input price, high exit rates and industrial oncentration. More precisely, we argue that falling input prices force firms with low productivity to exit and induce expansion of more efficient incumbents at the expense...

We analyze the impact of input tariffs on the export status and export performance of processing firms. From a theoretical model with heterogeneous downstream firms, we show that lower input tariffs may increase the export sales of the high productivity firms at the expense of low productivity...
