Recently, large-scale investigations have been launched around the world on allegations of possible collusion and manipulation of the London Interbank Offered Rate (“Libor”). These investigations followed empirical research that highlighted anomalous patterns in the Libor data. The Libor is...

In this paper we model cartel duration as a mixed proportional hazard model and condition on cartel characteristics such as the agency first detecting the cartel, industry, if it is a bid rigging or price fixing cartel, the number of countries affected, the affected sales, and measures of the...

In this paper we develop a general model of one-sided and two-sided platform businesses and apply it to a monopolist framework. We have a particular interest in how the social loss and other metrics depend on the strength of the network (direct or indirect) effect. We study how network effects...

The bloom is off the Big Tech rose. It seems nearly the entire political spectrum is angry with Amazon, Google and Facebook for one reason or another. This has led to a great deal of discussion on whether and how to regulate (or even break up) these platforms, including whether they should be...

This paper estimates three duration models, one for each of the three clinical phases of drug development using publicly available data. Specifically, we estimate three discrete time mixed proportional hazard models, with some parameter constraints across models. We present the estimated...

In this paper we apply a general model of one-sided and two-sided platform businesses to a collusive framework which we model as joint profit maximization. We have a particular interest in how the social loss and other metrics depend on the strength of the network (direct or indirect) effect. We...

In this paper we apply a general model of one-sided platform businesses to a duopoly competitive framework. We have a particular interest in how the option of multi-homing affects the competitive dynamic. We find that if multi-homing is precluded, the incumbent platform is always able to...
