Prof. Strausz erforscht derzeit die ökonomischen Mechanismen von Informationsasymmetrien und Vertragsgestaltung in digitalen Märkten, insbesondere im Kontext von Datenschutz und Verbraucherschutz. Sein aktueller Schwerpunkt liegt auf der Analyse, wie Unternehmen Daten sammeln und nutzen, wie Regulierung (wie die DSGVO) tatsächlich wirkt, und wie optimale Verträge unter Unsicherheit und Informationsproblemen gestaltet werden. Für Unternehmen und die öffentliche Hand bietet er theoretische Grundlagen und praktische Einsichten zur Gestaltung von Datenschutzrichtlinien, Zertifizierungsmechanismen und Preismodellen, die Verbraucherschutz mit wirtschaftlicher Effizienz verbinden. Seine Forschung ist relevant für digitale Plattformen, E-Commerce, Regulierungsbehörden und Unternehmen, die mit Verbraucherdaten arbeiten.

Abstract What is the best way to auction an asset? How should a group of people organize themselves to ensure the best provision of public goods? How should exchanges be organized? This book addresses these questions and more through an exploration of the economic theory of mechanism design. Mechanism design is reverse game theory. Whereas game theory takes the rules of the game as a given and makes predictions about the behavior of strategic players, the theory of mechanism design goes a step further and selects the optimal rules of the game. A relatively new economic theory, mechanism design studies the instrument itself as well as the results of the instrument. This book provides explanations of classic results in the theory of mechanism design, such as Myerson's theorem on expected revenue maximizing auctions, Myerson and Satterthwaite's theorem on the impossibility of ex post efficient bilateral trade with asymmetric information, and Gibbard and Satterthwaite's theorem on the non-existence of dominant strategy voting mechanisms. It also provides an examination of the frontiers of current research in the area.

Crowdfunding provides innovation in enabling entrepreneurs to contract with consumers before investment. Under aggregate demand uncertainty, this improves screening for valuable projects. Entrepreneurial moral hazard and private cost information threatens this benefit. Crowdfunding's after-markets enable consumers to actively implement deferred payments and thereby manage moral hazard. Popular crowdfunding platforms offer schemes that allow consumers to do so through conditional pledging behavior. Efficiency is sustainable only if expected returns exceed an agency cost associated with the entrepreneurial incentive problems. By reducing demand uncertainty, crowdfunding promotes welfare and complements traditional entrepreneurial financing, which focuses on controlling moral hazard. (JEL D21, D81, D82, D86, G32, L26)

This paper extends the revelation principle to environments in which the mechanism designer cannot fully commit to the outcome induced by the mechanism. We show that he may optimally use a direct mechanism under which truthful revelation is an optimal strategy for the agent. In contrast with the conventional revelation principle, however, the agent may not use this strategy with probability one. Our results apply to contracting problems between a principal and a single agent. By reducing such problems to well-defined programming problems they provide a basic tool for studying imperfect commitment.
