In this paper we show that bank competition has an intrinsically ambiguous impact on capital accumulation. We further show that it is also responsible for the emergence of development traps in economies that otherwise would be characterized by unique equilibria. These results explain the...

This paper shows that bank competition has an intrinsically ambiguous effect on capital accumulation and economic growth. We further demonstrate that banking market structure can be responsible for the emergence of development traps in economies that would otherwise be characterized by unique...

In this paper, I develop a model of oligopoly with shareholder voting. Instead of assuming that firms maximize profits, the objective of the firms is decided by majority voting. This implies that portfolio diversification generates tacit collusion. In the limit, when all shareholders are...

I model multimarket competition when consumers value firm scope across markets. Such competition is surprisingly common - consumers in many industries prefer firms that operate in more geographic and/or product markets. I show that these preferences permit firms of differing scopes to coexist in...

By distancing themselves from others in risk factor loadings, mutual funds yield distinct returns and become winning funds alternatively in different market situations. This enables mutual funds to obtain stochastic monopoly power and charge higher fees than they could otherwise. This strategy...

We explore the consequences from the two regulatory frameworks Dodd-Frank and EMIR for industrial corporates. We point out that - by falling under the clearing obligation - not only the corporate's option to decide freely on its positioning within the well-known “Risk Triangle” is...

We compare the structure and performance of private (non-GSE) mortgage-backed securities sold by large issuers vs. those sold by small issuers over the period 2000-2006. Securities sold by large issuers have less subordination — a greater fraction of the deal receiving AAA rating — than...

Dealer networks provide essential intermediation services in over-the-counter markets. We document the response of dealer networks to the arrival of new public information. We find that after public news releases, dealer networks become more complex and channel larger flows of securities between...

The traditional argument that shorter product cycles favor trade secret over patenting is reviewed. A game theoretic model provides an argument that shorter product cycles can induce firms to file more patent applications. The firms may be trapped in a prisoners' dilemma where all firms would...
