The population dynamics in a food chains are derived from a sequence of short- run equilibria of an ecosystem where predator species demand prey biomass, supply own biomass to their predators and are assumed to behave as if they maximize net biomass intake. Introducing prices as scarcity...

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...

Cultural capital is assumed to benefit all members of society. It is built up by the aggregate consumption of cultural goods and is diminished through depreciation. In the no-policy market economy, consumers tend to ignore the beneficial external effects of their cultural good consumption on the...

We analyse tax competition with corporate profit taxes in a common market where tax revenues are allocated according to an apportionment formula. As a general rule, tax competition is sharper the higher is the tax elasticity of the apportionment formula which, in turn, depends on the properties...

Recently macroeconomic researchers have begun studying models of optimal monetary policy within the Real Business Cycle (RBC) framework. A standard RBC model is augmented by New Keynesian elements like sticky prices and monopolistically competitive firms. The monetary authority acts as a social...

For a durable consumption good which turns into waste after consumption, the socially optimal durability increases with an increase in the marginal environmental damage. In a laissez-faire equilibrium under perfect competition, producers fail to provide an efficient product design, i.e....

We examine two types of altruism and their implications for voluntary giving. Philanthropists are altruists who wish to enhance the well-being of others, while individuals with merit-good preferences only wish to further the consumption of certain merit goods by others. Philanthropic donors...
