My research uses microeconomics and game theory to investigate questions in public & political economics, industrial & health economics and contest theory. It aims to deepen our understanding of economic institutions, which are defined as a set of rules that determine economic interactions, and to investigate the effectiveness of institutions in solving the underlying economic problems.

The questions that I have explored encompass a wide range of applications that are of substantial economic importance, including:

  • Overtreatment and rising health care costs — How should payments to physicians be designed in order to provide incentives to make an appropriate diagnosis?
  • Selective reporting of clinical trial results — How should the environment in which pharmaceutical companies undertake clinical trials be designed in order to improve clinical knowledge?
  • Campaign finance reform — What are the implications of the fact that interest groups provide both contributions and policy advice to politicians?
  • Social acceptance of affirmative action policies — Given that some affirmative action policies lack social acceptance because they are thought to weaken competition, are there affirmative action policies that actually strengthen competition?

On way to see the how these and most of the other questions in my research agenda are connected is through the lens of influence activities. My research aims to understand how economic agents strategically influence decisions of other agents, how these activities are affected by competition, and how the environment in which these activities take place should be designed. There are two ways to influence decisions. On one hand, influence can provide incentives — for example when an explicit payment makes one alternative more attractive than others. On the other hand, influence can change beliefs — for example when after receiving advice one alternative seems more appropriate than others.

On this web site I organize my research broadly in three categories. First, influence plays an important role in industrial & health economics — for example in procurement auctions, when firms decide whether to reveal information about product risk, or in the interaction between a physician and his patient. Second, influence is an important determinant in public & political economics — for example when interest groups lobby politicians or members of a legislature vote over some proposal. Third, many economic, political and social environments can be characterized as situations in which agents compete by investing costly resources in order to influence their prospects of winning some prize. Examples include lobbying, litigation, political campaigns, military conflict, patent races, arms races, sports events, promotional competition, labour market tournaments or R&D competition. The systematic analysis of competition under these conditions has become known as contest theory.
