Prof. Lang is an applied microeconomic theorist who studies human behavior under uncertainty. In particular, he is interested in uncertainty that cannot be quantified exactly. In addition, he explores useful aspects of uncertainty and contractual arrangements mitigating the effects of uncertainty. As a researcher, he finds these questions fascinating. Matthias Lang has studied communication of subjective information, strategic uncertainty, and uncertainty in contract enforcement. He uses techniques drawn from game theory, mechanism design, decision theory, psychology, and probability theory.
Applications of his work include deterrence of insurance fraud and tax evasion, choices of unhealthy behavior, political competition, research contests and competition law.
