Economic theory provides ambiguous and conflicting predictions about the association between algorithmic pricing and competition. In this paper we provide the first empirical analysis of this relationship. We study Germany's retail gasoline market where algorithmic-pricing software became widely...

Numerous recently uncovered cartels operated along the supply chain, with firms at one end facilitating collusion at the other - hub-and-spoke arrangements. These cartels are hard to rationalize because they induce double marginalization and higher costs. We examine Canada's alleged bread cartel...

We study cartels that operated in the US generic drug industry, leveraging quarterly Medicaid data from 2011-2018 and a difference-in-differences approach comparing the evolution of prices of allegedly collusive drugs with a group of competitive control drugs. Our analysis highlights (i) the...

The analysis of new product introduction using discrete-choice demand models has focused on successful products (e.g. the minivan) and their welfare impacts. Instead, we apply this approach to unsuccessful products to provide insight into the reasons for their failure. Our case study is the...

The FDIC resolves insolvent banks using an auction process in which bidding is multidimensional and the rule used to evaluate bids along the different dimensions is proprietary. Uncertainty about the scoring rule leads banks to simultaneously submit multiple differentiated bids. This resolution...

Following the crisis, macroprudential regulations targeting mortgage-market vulnerabilities were widely adopted, their success often depending on intermediaries' responses. We show that Canadian banks behaved strategically to limit the potency of recently implemented mortgage stress tests,...

A number of recent papers have proposed that a pattern of isolated winning bids may be associated with collusion. In contrast, others have suggested that bid clustering, especially of the two lowest bids, is indicative of collusion. In this paper, we present evidence from an actual procurement...

In an effort to lower costs of provision, authorities have encouraged the consolidation of providers for a number of services such as electricity distributors, school boards, hospitals, and municipalities. In this paper we propose an endogenous merger process to evaluate the impact of...
