This paper studies the design of the optimal non linear taxation in an economy where longevity varies across agents, and depends on three factors: longevity genes, health investment and farsightedness. Provided earnings, farsightedness and genes are correlated, governmental intervention can be...

On a heterogeneous experimental oligopoly market, sellers choose a price, specify a set-valued prior-free conjecture about the others' behavior, and form their own profit-aspiration for each element of their conjecture. We formally define the concepts of satisficing and prior-free optimality and...

A general framework is described specifying how boundedly rational decision makers generate their choices. Starting from a Master Module which keeps an inventory of previously successful and unsuccessful routines several submodules can be called forth which either allow one to adjust behavior...

Our societies are witnessing a steady increase in longevity. This demographic evolution is accompanied by some convergence across countries, whereas substantial longevity inequalities persist within nations. The goal of this paper is to survey some crucial implications of changing longevity on...

This paper analyzes the impact of demographic aging on capital accumulation and welfare in economies with unfunded pensions. Using a two-period overlapping generation model with potentially endogenous retirement decisions, it shows that both the type of aging, i.e. declining fertility or...

Predator-prey relationships account for an important part of all interactions between species. In this paper we provide a microfoundation for such predator-prey relations in a food chain. Basic entities of our analysis are representative organisms of species modelled similar to economic...

We analyse tax competition with corporate income taxes in a common market where tax revenues are allocated according to an apportionment formula. Generally, tax competition is sharper (i.e., equilibrium tax rates are lower) the more tax-elastic is the apportionment formula. This depends on the...
