This paper investigates the substitution possibilities in the production function between capital and two labour inputs, skilled and unskilled workers. We estimate a very general system of factor demand at the firm level, using original panel data obtained by merging three different sources. We...

We estimate a conditional convergence equation derived from an augmented Solow model where human capital is defined as skilled labour. We implement Generalized Method of Moments (GMM) estimators on a panel of countries. Estimation is carried out on the model in levels instrumented by the lagged...

Using a unique dataset merging micro data at product and store level with data on competition within local grocery markets, this paper provides an empirical analysis of a legislation that had the same effect as allowing industry-wide price floors. It shows that, after the introduction of the...

We implement an original method based on the estimation of a production function, toinvestigate how the decrease in the cost of computers has affected the marginal cost of firms,their aggregate labor demand and their skill structure. Using a panel of more than 5000French firms followed between...
