When firms decide to invest in R&D, they have to choose not only the amount of resources to invest, but also which research projects to develop. This paper investigates the market portfolio of research projects. Contrary to most of the literature, which focuses only on the level of investment in...

Contrary to most of the literature, which focuses only on the level of investment in innovation, this paper examines both the variety of research projects undertaken and the amount of duplication of research. A characterization of the equilibrium market portfolio of R&D projects and the socially...

This article examines the effects of market structure on the variety of research projects undertaken and the amount of duplication of research. A characterization of the equilibrium market portfolio of R&D projects and the socially optimal portfolio is provided. It is shown that a merger...

We study the effects of different information structures (full information, supply uncertainty and demand uncertainty) on equilibrium prices, allocative efficiency and bidding behavior in a (supply-side) uniform-price multi-unit auction, using supply function competition and a novel experimental...

We conduct a large scale randomized field experiment to study whether providing recipients - 42,454 Chinese households in a rural area - with information on the costs of a real decision they make can help to improve the quality of their choices. The decisions are of high financial impact, as the...

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...

I present a game-theoretic model where economic competition and attention competition are interdependent. On the one hand the effort to attract consumer attention depends on the value of attention to the firm which depends on the grade of price competition among all perceived firms. On the other...
