Creative Destruction and Productive Preemption

Norbäck, Pehr-Johan; Persson, Lars; Svensson, Roger - Institutet för Näringslivsforskning (IFN) - 2009

We develop a theory of commercialization mode (entry or sale) of entrepreneurial inventions into oligopoly, and show that an invention of higher quality is more likely to be sold (or licensed) to an incumbent due to strategic product market effects on the sales price. Moreover, preemptive...

Why Entrepreneurs Choose Risky R&D Projects - But Still Not Risky Enough

Färnstrand Damsgaard, Erika; Norbäck, Pehr-Johan; … - Institutet för Näringslivsforskning (IFN) - 2012

. We also show that commercialization support induces entrepreneurship but may lead to mediocre entrepreneurship by … inducing entrepreneurs to choose less risky projects, whereas R&D support encourages entrepreneurship without affecting the … type of entrepreneurship. Using Swedish patent citation data, we find empirical support for predictions of the model. …

The Gains from Pension Reform

Lindbeck, Assar; Persson, Mats - Institutet för Näringslivsforskning (IFN) - 2002

degree of funding implies mainly a redistribution of income among generations, although a partial shift to funding also …

Can and Should a Pay-As-You-Go Pension System Mimic a Funded System?

Hassler, John; Lindbeck, Assar - Institutet för Näringslivsforskning (IFN) - 1998

This paper considers the possibility of letting a pay-go pension system mimic a fully funded pension system. Generically, it turns out to be impossible to make a less than fully funded pension system actuarially fair on average. But a non-funded pay-go pension system can provide an actuarially...

Evolution and Refinement with Endogenous Mistake Probabilities

van Damme, Eric; Weibull, Jörgen W. - Institutet för Näringslivsforskning (IFN) - 1999

Bergin and Lipman (1996) show that the refinement effect from the random mutations in the adaptive population dynamics in Kandori, Mailath and rob (1993) and Young (1993) is due to restrictions on how these mutation rates vary across population states. We here model mutation rates as...

What have we learned from Evolutionary Game Theory so far?

Weibull, Jörgen W. - Institutet för Näringslivsforskning (IFN) - 1997

Evolutionary theorizing has a long tradition in economics. Only recently has this approach been brought into the framework of non-cooperative game theory. Evolutionary game theory studies the robustness of strategic behaviour with respect to evolutionary forces in the context of games played...

Social Networks

de Marti, Joan; Zenou, Yves - Institutet för Näringslivsforskning (IFN) - 2009

We survey the literature on social networks by putting together the economics, sociological and physics/applied mathematics approaches, showing their similarities and differences. We expose, in particular, the two main ways of modeling network formation. While the physics/applied mathematics...

Clever Agents in Young's Evolutionary Bargaining Model

Weibull, Jörgen W.; Saez-Marti, Maria - Institutet för Näringslivsforskning (IFN) - 1998

In the models of Young (1993a,b), boundedly rational individuals are recurrently matched to play a game, and they play myopic best replies to the recent history of play. It could therefore be an advantage to instead play a myopic best reply to the myopic best reply, something boundedly rational...

Deterministic Approximation of Stochastic Evolution in Games

Benaim, Michel; Weibull, Jörgen W. - Institutet för Näringslivsforskning (IFN) - 2000

This paper provides deterministic approximation results for stochastic processes that arise when finite populations recurrently play finite games. The deterministic approximation is defined in continuous time as a system of ordinary differential equations of the type studied in evolutionary game...
