The paper examines the influence of altruism on voluntary transfers and government redistribution in a simple model: two jobs of different productivity are assigned by chance to two individuals. Ex ante the individuals are identical, ex post they have different incomes. The first part of the...

The paper considers environmental regulation of a consumption good and an externality which influence demand and costs in a nonseparable way. Under monopoly two instruments are always required for first-best. The Pigouvian tax is more complicated than anticipated. Copyright Kluwer Academic...

his paper presents a unifying approach to modelling endogenous tastes. Tastes are defined as orderings of a subspace of a (suitable chosen) commodity space. Using this definition endogenous tastes are analytically similar to externalities. Accordingly, many models in economic theory can be...

The paper presents an algorithm that solves two-point boundary-value problems that arise in economic control models in continuous time with an infinite time horizon and several state variables. The algorithm can determine optimal trajectories that converge to an isolated equilibrium point. It...
