Competitive tension refers to pressure that is considered to exist among firms operating in a competitive market and that forces them to take competitive action against each other. An imaginary upper limit of competitive tension symbolizes the difference between whether to take competitive...

Theory suggests that by lending to a firm, inside banks gain an informational advantage over non-lender outside banks. This informational gap hinders borrowers from switching lenders due to a winner's curse faced by competing outside banks, leading to hold-up problems. In this paper, we show...

Antitrust laws prohibit private firms to coordinate their market behavior, yet many types of interfirm cooperation are legal. Using laboratory experiments, we study spillovers from legal cooperation in one market to non-competitive prices in a different market. Our theoretical framework predicts...

Non-bank financial institutions, such as principal-trading firms and hedge funds, increasingly compete with bank-owned dealers in fixed-income markets. Some market participants worry that if non-bank financial institutions push out established bank dealers, liquidity will become unreliable...

Compatibility of network products is an important issue in markets for communication technology as well as hard- and software products. Empirical findings suggest that firms competing in these markets typically choose intermediate degrees of product compatibility. We present a strategic...

The diffusion of automation technology raises questions about the future of work, leading to calls for policy interventions. The ongoing debate centers on the decisions made by technology adopters. In this paper, I study supply-side adjustments and their role in shaping policy outcomes. I focus...

This paper provides a simple unified discrete-choice framework for analyzing differentiated duopolies. This framework nests models of horizontal and vertical differentiation, including standard textbook models (Hotelling and Shaked-Sutton). Contrary to these models, it also applies to economic...

By affecting prices and thereby market shares of green and brown firms, product innovations and process innovations influence industry emissions even when they do not directly affect the emission intensity of the innovating firm. Using a differentiated two-stage duopoly, this paper therefore...

Die derzeit hohe Inflation wird auch durch hohe Monopolrenten von Konzernen getrieben. Es liegt nicht eine Lohn-Preis-, sondern eine Gewinn-Preis-Spirale vor. Die Monopolrenten sind möglich, da zuletzt vor allem durch Firmenübernahmen marktbeherrschende Unternehmen entstanden sind. Auch...

We consider a downstream duopoly model with a monopolistic common supplier and mutual outsourcing between the two symmetric downstream firms. The market structure captures the recent procurement environment in the smartphone industry. We also incorporate managerial delegations into the duopoly...
