This paper shows that a neoclassical model with standard assumptions but endowed with an explicit age structure of the population, converges to its balanced growth path with damped oscillations. It therefore reproduces a trend-reverting process with short run fluctuations that is displayed by...

This review of the literature presents the main tools and results of research at the crossroads between finance and macroeconomics. The literature seeks to jointly analyze the economic cycle and fluctuations in financial-asset prices.Our article follows this approach:we offer a critical analysis...

We study information transmission between informed experts and an uninformed decision-maker who only takes binary decisions. In the single expert case, we show that information transmission can only be relatively poor. Hence, even sophiscated communication games do not yield equilibria which (ex...

We propose a simple model which embeds cost allocation games into a richer structure to take into account that information on costs can be itself costly. The model is an outgrowth of experience on cost allocation for consortia of municipalities dealing with garbage collection.
