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...

We have implemented a new methodology in order to examine the effect of Information Technologies (IT) on Multifactor Productivity (MFP) at the firm level. Although the skill biased technical change hypothesis has received a lot of empirical support, previous studies typically assumed that input...

In this article we evaluate the contribution of information and communication technologies (ICT) to the growth of value added during the past 15 years in France. Following North American studies, we use traditional growth accounting methods to assess the relative size of two types of...
