This study shows how cod subpopulations may have been eradicated as a consequence of the use of imperfect models for assessing stock assessment, depleting what was formerly a productive sea. The Kattegat and resund (North Sea) were chosen as study objects due to the combination of different exploitation patterns and the possible existence of separate stock units. The scenario was further elaborated by simulating the potential harvest of fishing for different long-run levels of fishing effort as well as stock size.

The purpose of this report is to build knowledge about the effects of the development of regional and international carbon markets and the auxiliary technology agreements that might be needed.

This analysis of the fishers’ compliance with regulations in Lake Victoria, Tanzania, gives support to the traditional economics-of-crime model and shows that the extension of the basic deterrence model can lead to a richer model with substantially higher explanatory power.

This article uses data from household- and plot-level surveys conducted in the highlands of the Tigray and Amhara regions of Ethiopia. We examine the contribution of sustainable land management (SLM) practices to net value of agricultural production in areas with low vs. high agricultural potential.

Using a choice experiment, this paper investigates how Swedish citizens value three environmental quality objectives. In addition, a follow-up question is used to investigate whether respondents ignored any attributes when responding.

From 1997 to 2005, an astonishing 5200 million USD was invested to reduce cocaine production in Colombia, the world's main cocaine producer. However, little is known about the effectiveness of policies targeting coca cultivation. This paper uses a survey-based experiment to evaluate the effects of the two main policies: eradication and alternative development programs.

Urbanization has been mentioned as one possible cause of higher food prices, and in this paper we examine some of the suggested links between urbanization and food prices.

The paper analyses the economic impacts of climate change-induced adjustments on the performance of the Tanzanian economy, using a country-wide CGE model. The general equilibrium framework enables comparison of the effects of climate change to the overall growth of the economy, as responsiveness to shocks is likely to depend on the macroeconomic structure of the economy.

This paper analyzes the effects of the interaction between technology adoption and incomplete enforcement on the extent of violations and the rate of abatement technology adoption. We focus on price-based and quantity-based emission regulations. First, we show that in contrast to uniform taxes, under tradable emissions permits (TEPs), the fall in permit price produced by technology adoption reduces the benefits of violating the environmental regulation at the margin and leads firms to modify their compliance behavior.
