Competition in many important industries centers on investment in intellectual property. Firms engage in dynamic, Schumpeterian competition for the market, through sequential winner-take-all races to produce drastic innovations, rather than through static price/output competition in the market....

Market definition and market power are central features of competition law and practice but pose serious challenges. On one hand, market definition suffers decisive logical infirmities that render it infeasible, unnecessary, and counterproductive, and the practice of stating market power...

This Chapter provides a survey of the economics literature on multi-sided platforms with particular focus on competition policy issues, including market definition, mergers, monopolization, and coordinated behavior. It provides a survey of the general industrial organization theory of...

The purpose of this paper is to estimate the effect of state criminal justice expenditures and state public health expenditures on deterring illicit drug use. The empirical model is based on a demand and supply model of drug markets. The effect of a given expenditure on criminal justice or...

States, which have the primary legal role in regulating the prescribing and dispensing of prescription medications, have created Prescription Drug Monitoring Programs (PDMP) to try to reduce inappropriate prescribing, dispensing, and related harm. Research assessing whether these interventions...

We study the spillover effects of prescription drug monitoring programs (PDMPs) on crime, and in the process inform how policies that restrict access to Rx opioids per se within the healthcare system would impact broader non-health domains. In response to the substantial increase in opioid use...

Standard models of hierarchy assume that agents and middle managers are better informed than principals about how to implement a particular task. We estimate the value of the informational advantage held by supervisors (middle managers) when ministerial leadership (the principal) introduced a...

This paper characterizes the efficient sequential equilibrium when a government uses indirect control to exert its authority. We develop a dynamic principal-agent model in which a principal (a government) delegates the prevention of a disturbance--such as riots, protests, terrorism, crime, or...

We study the re-arrest rates for two groups: individuals formerly in prison and individuals formerly under electronic monitoring (EM). We find that the recidivism rate of former prisoners is 22% while that for those 'treated' with electronic monitoring is 13% (40% lower). We convince ourselves...

This paper examines the impact of partisan control of the media on news content and viewership by consumers with differing ideologies. We use data from Italy, where the main private television network is owned by Silvio Berlusconi, the leader of the center-right coalition, and the public...
