In the middle of the nineties, the sharp increase in globalisation and the last privatization wave have promoted the shaping of a market for executives in France. Characteristics of this market are estimated for France and a competitive model is simulated in order to assess to what extend such a...

Using data from the US automobile market, we empirically examine the link between competition and innovation. Consistent with a large literature, we use patent counts as a measure of innovation. The combination of the US market's economic importance, market dynamics, and the significant...
