I study the effects of improved public information on equilibrium welfare and price dispersion, providing sufficient conditions for negative and positive effects. Public information affects welfare by reducing excessive (though rational) pessimism induced by sequential learning. Reduced...

The paper outlines a static equilibrium model, which analyses the economic development in a two-country case by considering interregional migration in R&D-sectors. The effects of migration and firm decisions on both industrial agglomeration and economic development will be shown: lock-in-effects...

Various approaches used in Agent-based Computational Economics (ACE) to model endogenously determined interactions between agents are discussed. This concerns models in which agents not only (learn how to) play some (market or other) game, but also (learn to) decide with whom to do that (or not).

Model-Free Reinforcement Learning has achieved meaningful results in stable environments but, to this day, it remains problematic in regime changing environments like financial markets. In contrast, model-based RL is able to capture some fundamental and dynamical concepts of the environment but...

This work, which shall contribute to the Fest "A Just Society: Honouring Joseph Stiglitz", discusses a major unifying theme in Joe Stiglitz monumental work, namely, the analysis of economies characterised by persistent learning and coordination hurdles. In his analysis Joe is in many respects a...

Consider a multi-sector general equilibrium model where firms have incomplete information about the returns to scale of their production and where that information is sequentially updated once real production is observed. What is the impact of this learning dynamics on the market-wise...

This paper investigates the impact of the history of crises on macroeconomic performance. We first study the impact of past banking crises on the probability of a future banking crisis. Applying data for 1980 - 2010 for all countries for which the required information is available, controlling...

We investigate the effectiveness of an aggressive anti-inflation monetary policy on the ability of agents to achieve rational expectations equilibrium (REE) forecasts of inflation. An aggressive anti-inflation policy includes a willingness to respond more forcefully to deviations from an...

This paper investigates the effect of an aggressive price stabilizing monetary policy on the ability of agents to reach a rational expectations equilibrium (REE) for inflation and output. We provide a more robust policy implication than the one suggested by Bullard and Mitra (2002a,b). Using an...
