We study a consumer boycott on cottage cheese that was organized in Israel on Facebook in the summer of 2011 following a steep increase in prices after price controls were lifted in 2006. The boycott led to an immediate decline in prices which stayed low more than three years after the boycott....

This paper shows how competing firms can facilitate tacit collusion by making passive investments in rivals. In general, the incentives of firms to collude depend in a complex way on the whole set of partial cross ownership (PCO) in the industry. We show that when firms are identical, only...

We document the evolution of productivity in a steel mini mill with fixed capital, producing an unchanged product with Leontief technology. Despite almost un- changed production conditions, output doubles within the sample period (12 years). We decompose the gains into: downtime reductions, more...

This paper considers three firms that engage in an R&D contest to develop a new profitable technology. For a broad range of parameters, the firm that leads the contest (i.e., has the highest probability of success) is better-off licensing or selling its superior interim knowledge to one of the...

We examine the implications of pre-grant publication (PP) of patent applications in the context of a cumulative innovation model. We show that pre-grant publication of patents lead to fewer applications and fewer inventions, but it raises the probability that new technologies will reach the...

We develop a theory of organization design in which the firm's structure is chosen to mitigate moral hazard problems in the selection and the implementation of projects. For a given set of projects, the divisional structureʺ which gives each agent the full responsibility over a subset of...

This paper examines the incentive of unpaid programmers to contribute to open source software (OSS) projects in order to signal their talents. The analysis shows that if programmers contribute to OSS projects at all, then generically there are multiple equilibria. In these equilibria, an...
