Sunk costs, contestability, and the latent contract market
The idea that an industry with sunk costs may be contestable even in the absence of long-term contracts has received little attention from formal economic theory yet is popular among monopolists facing antitrust suits. The paper formally illustrates the argument. In an infinitely repeated game, there exists a class of contestable outcomes in which the monopolist sells only on the spot market and charges low prices along the equilibrium path to prevent customers from resorting to long-term contracts. Then, the crucial test for contestability is the level of transaction costs in the latent ...

Are there regimes of antitrust enforcement? An empirical analysis
In this paper, the authors propose a new index of antitrust enforcement.

The authors use Hamilton's (1989, 1990) regime-switching technique to estimate a model in which the enforcement index follows a regime-specific AR(1) process. The authors find evidence of long-lived regimes. The high enforcement regime, which lasted from about 1910 to the mid-1960s, produced enforcement that was, on average, almost twice as ...
