Substantial evidence has accumulated in recent empirical works on the limited ability of the Nash equilibrium to rationalize observed behavior in many classes of games played by experimental subjects. This realization has led to several attempts aimed at finding tractable equilibrium concepts...

We study extrapolation between games in a laboratory experiment. Participants in our experiment first play either the dominance solvable guessing game or a Coordination version of the guessing game for five rounds. Afterwards they play a 3x3 normal form game for ten rounds with random matching...

We study (anti-) coordination problems in networks in a laboratory experiment. Partici- pants interact with their neighbours in a fixed network to play a bilateral (anti-) coordination game. Our main treatment variable is the extent to which players are heterogeneous in the number of connections...

We present a simple procedure that selects the strategies most likely to be played by inexperienced agents who interact in one shot 2x2 matching pennies games. As a first step we axiomatically describe players' beliefs. We find the minimax regret criterion to be the simplest functional form that...

Cooperation in international environmental agreements appears difficult to attain because of strong free-riding incentives. This paper explores how different technology spillover mechanisms among regions can influence the incentive structures to join and stabilise an international agreement. We...

This paper develops and tests a dynamic optimization model of fishermen's investment behavior in a limited-entry fishery. Because exit from limited-entry fisheries may be irreversible, the fisherman has an incentive to maintain the right to fish (whether by actually fishing or by purchasing an...

Strategies of international risk management, as the implementation of tradable emission permits, feed back to the incentive structure of a treaty, like the Kyoto Protocol. Discussing the Kyoto Protocol the question was: Should there be any restrictions on the trading of emission permits or not?...

In this paper we consider a two periods model of cropping using irrigation. The farmer takes two kind of decisions, one related to the level of investment in irrigation capacity and the other one to the irrigation level in each period. In the first period, decisions are taken under uncertainty...

Governments contracting with private agents for the provision of an impure public good must contend with agents who would potentially supply the good absent any payments. This additionality problem is centrally important in the use of carbon offsets as part of climate change mitigation....

When economic agents decide their optimal environmental behavior, they have to take into account non continuos evolutionary trends and irreversible changes characterising environmental phenomena. Given the still non perfect biophysical and economic knowledge, decisions have to be taken in an...
