This paper studies an effect of a horizontal merger where a product consolidation by the merged firm may alter the substitutability in the industry. We show that as the number of firms in the industry increases, this type of merger becomes profitable for merging firms, while unprofitable for...

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...

This paper studies the stability of mergers between firms in a Cournot market. Unlike most existing works, we consider a demand structure where the substitutability between firms is asymmetric. We specifically focus on the stability of the grand coalition by analyzing the core allocation. The...
