The paper sets up a four-stage enforcement model of fish quotas. The purpose of the paper is to show how the level of enforcement set by the authorities af-fects the way fishermen form coalitions. We show that a high level of control effort yields less cooperation among fishermen, while in the...

This paper considers the policy outcome of a contest between two opposing in-terest groups: the incumbent fishermen and a group of conservationalists. The objective of the fishermen is to maximize profit, and they are (partly) concerned over future profitability as well, while the...

Real life implies that public procurement contracting of renewable resources results in repeated interaction between a principal and the agents. The present paper analyses ratchet effects in contracting of renewable resources and how the presence of a resource constraint alters the "standard"...

In Zusammenhang mit der Diskussion um eine nachhaltige Entwicklung in Deutschland werden ökonomische Steuerungsinstrumente erörtert, deren Einsatz auf eine Begrenzung des durch kommunale Baugebietsausweisungen induzierten "Flächenverbrauchs" abzielt. Vor diesem Hintergrund wird in dem...

The paper analyzes effects of randomized response with respect to some binary dependent variable on the estimation of the probit model. This approach is used in interviews when asking sensitive questions. Alternatively randomization can be considered as a means of statistical disclosure control...

The paper uses micro cross-section data from the GfK consumer panel for econometric demand analysis of private households in Germany. Contrary to most research which considered \average behavior we extend this approach to consumer behavior for di®erent \intensities of consumption. Our...

This paper provides an example in which a slight behavioral heterogeneity may fundamentally change the qualitative properties of a nonlinear cobweb market with a quadratic cost function and an isoelastic demand function. We consider two types of producers; adaptive and naive. In a market of...

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...
