We apply the stochastic evolutionary approach of equilibrium selection to macroeconomic models in which a complementarity at the macro level is present. These models often exhibit multile Pareto-ranked Nash equilibria , and the best response-correspondence of an individual increases with a...

I study an evolutionary model of equilibrium selection in supermodular games where players are involved in simultaneous play. This is taken to refer to a context, in contrast with most evolutionary literature, where players' objective is to have their actions match a certain statistic of the...

This report reviews Thomas J. Sargents essay 'The Conquest of American Inflation' (1999). Sargent searches for a model which can explain postwar US inflation and which may shed light on the dynamic forces which drive this pattern. Following Sargent, the conquest of US inflation is due to a...

We provide a framework for analysing the choice between optimal and robust rules in the presence of paradigm uncertainty in monetary policy. We thus provide two issues: first, we discuss the conditions of uncertainty that render a robust rule a preferable substitute to optimal rules and second,...

Since the 1950's economists applied game theoretical concepts to a wide variety of economic problems. The Nash equilibrium concept has proven to be a powerful instrument in analyzing the outcome of economic processes. Since the late 1980's economists also show a growing interest in the...

In this paper we evaluate a Norwegian vocational rehabilitation program by comparing employment outcomes of trainees and nonparticipants using nonexperimental data. A matching estimator is used to calculate the training effect for different subgroups of the sample. We demonstrate how bounding...

The paper discusses how this relatively strong price response should be interpreted in the context of other econometric analysis with no explicit appliance dependence. Finally, the significance of the many household charcteristics at both stages of the model signals a high degree of...

We evaluate the costs of three different programs for alleviating long term poverty: (i) workfare, or grants made contingent on a work requirement, (ii) universal welfare, or unconditional grants, and (iii) means-tested welfare, or grants conditioned on private labor market earnings. We identify...
