Investment in R&D is positively associated with the variance of sales growth and, to a lesser extent, employment growth. The magnitude of this effect has not increased in recent decades, however.

We construct a new database by matching firm-level Compustat data to NBER patent data, for four 2-digit complex technology sectors. Whilst conventional regression estimators show that the stock market does recognise efforts at innovation, quantile regression analysis adds a new dimension to the...

While Gibrat's Law assumes that growth rate variance is independent of size, empirical work has usually found a negative relationship between growth rate variance and firm growth. Using data on French manufacturing firms, we observe a relatively low, but statistically significant, negative...

In this note, we suggest a link between tariff protection and firms' incentives to engage in a horizontal merger. We consider a Cournot oligopoly with equal, constant marginal costs where firms have to decide on lobbying efforts prior to choosing output. These lobbying efforts will determine...

We show that if firms in an industry engage in third-degree price discrimination, the number of firms in the free-entry equilibrium may be inefficiently low. This result is obtained even with set up costs and a price above marginal cost. We discuss the relevant implications that our result has...

We propose an incomplete contract model of licensing of a cost-reducing technology. We incorporate exchange rate uncertainty and analyze its impact on the parties' investment and licensing decisions. We show that exchange rate uncertainty introduces a distortion in the parties' specific...
