We analyze a client's choice of contract in auctions where Dutch law firms compete for cases. The distinguishing feature is that lawyers may submit bids with any fee arrangement they prefer: an hourly rate, a fixed fee or a \mixed fee," which is a time-capped fixed fee plus an hourly rate for any additional hours should the case take longer than expected. This format of selling legal services is unusual ...

We investigate the welfare impact of parallel imports using a large panel dataset containing monthly information on sales, ex-factory prices, and further product characteristics for all 649 anti-diabetic drugs sold in Germany between 2004 and 2010. We estimate a two-stage nested logit model of demand, and on the basis of an oligopolistic model of multi-product firms, we then recover the marginal costs ...

This paper tests whether upstream R&D cooperation leads to downstream collusion. We show that a sufficient condition for identifying collusive behavior is a decline in the market share of RJV-participating firms. Using information from the U.S. National Cooperation Research Act, we estimate a market share equation correcting for the endogeneity of RJV participation and R&D expenditures. We find robust ...
