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...

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 … network formation. While the physics/applied mathematics approach is capable of reproducing most observed networks, it does … not explain why they emerge. On the contrary, the economics approach is very precise in explaining why networks emerge but …

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...

Deterministic Approximation of Stochastic Evolution in Games.

Benaim, M.; Weibull, J.W. - Institutet för Näringslivsforskning (IFN) - 2000

This paper provides deterministic approximation results for stochastic processes that arise when finite populations of boundedly rational agents recurrently play finite games. The deterministic approximation is defined in continuous time in terms of a system of ordinary differential equations of...

Uniqueness in Infinitely Repeated Decision Problems

Vieille, Nicolas; Weibull, Jörgen W. - Institutet för Näringslivsforskning (IFN) - 2002

Dynamic decision-making without commitment is usually modelled as a game between the current and future selves of the decision maker. It has been observed that if the time-horizon is infinite, then such games may have multiple subgame-perfect equilibrium solutions. We provide a sufficient...

Evolution with Mutations Driven by Control Costs

Weibull, Jörgen W.; van Damme, Eric - Institutet för Näringslivsforskning (IFN) - 1998

Bergin and Lipman (1996) show that the refinement effect from the random mutations in the adaptive 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 these mutation rates as endogenously...

Direct Investment and Local Content Rules in the European Community

Andersson, Thomas - Institutet för Näringslivsforskning (IFN) - 1990

This paper analyses the behaviour of competing governments in the EC with respect to inflows of direct investment. Solving a non-cooperative sequential bargaining game in which host countries gain from direct investment through tax revenue or imposition of forced local subcontracting, it is...

Investment Lilberalization - Why a Restrictive Cross-Border Merger Policy can be Counterproductive

Norbäck, Pehr-Johan; Persson, Lars - Institutet för Näringslivsforskning (IFN) - 2006

Investment liberalizing countries are often concerned that cross-border mergers & acquisitions, in contrast to greenfield investments, might have an adverse effect on domestic firms and consumers. However, given that domestic assets are sufficiently scarce, we identify a preemption effect and an...

Poverty in Rural Cambodia: The Differentiated Impact of Linkages, Inputs and Access to Land

Engvall, Anders; Sjöberg, Örjan; Sjöholm, Fredrik - Institutet för Näringslivsforskning (IFN) - 2007

Cambodia has been growing rapidly over the past few years but still remains one of the poorest countries in East Asia. In particular, poverty is widespread in rural Cambodia. This paper examines rural poverty in Cambodia with a view to furthering our understanding of the factors that might...
