We study the impact of broadband availability on firms' total factor productivity (TFP) using German firm-level data between 2010 and 2015. We adopt a control function approach to causally identify and separately estimate productivity for 46 two-digit manufacturing and service sectors. Over the...

We study a merger between two Dutch supermarket chains to assess its effect on the depth as well as composition of assortment. We adopt a difference-in-differences strategy that exploits local variation in pre-merger competitive conditions and thus in the merger outcomes. To define our control...

This paper tests whether upstream R&D cooperation leads to downstream collusion. We consider an oligopolistic setting where firms enter in research joint ventures (RJVs) to lower production costs or coordinate on collusion in the product market. We show that a sufficient condition for...

This paper empirically evaluates the price effects of the merger of two major book retail chains in the UK: Waterstone's and Ottakar's. We employ differences-in-differences techniques and use a rich dataset containing monthly scanner data information on a sample of 200 books sold in 60 stores in...
