Unlike in Asia, the manufacturing sector has not (yet) become a driver of structural change in Africa. One common explanation is that the natural resource-focus of many African economies leads to Dutch disease effects. To test this argument for the case of newly found oil in Ghana we develop a...

In this paper, we present a standard quality ladders endogenous growth model with one significant new assumption, that it takes time for firms to learn how to export. We show that this model without Melitz-type assumptions can account for all the evidence that the Melitz (2003) model was...

For analyzing the impact of climate change and of international climate policies on the international division of labor and on regional welfare the use of a disaggregated multi–sectoral, multi–regional dynamic computable general equilibrium model is appropriate. This paper discusses the...

Most dynamic trade models assume steady state or balanced growth. This paper argues while this can be done in a single region model or a model without trade, the steady state assumption is problematic in a multi-regional setting with trade interactions. This paper shows the consequences of...

Die Gebietskörperschaften in Deutschland sind zunehmend bestrebt, private Finanzierungsmodelle für den Bau und den Betrieb von Einrichtungen der Verkehrsinfrastruktur zu realisieren. Vor diesem Hintergrund wird versucht, mittels einer detaillierten Auswertung der Haushaltspläne des Bundes und...

This paper presents a Computable General Equilibrium (CGE) model for the analysis of environmental policies towards mining activities, and shows for the case of South Africa how it can be implemented numerically. The CGE model belongs to the class of static, trade-focussed models along the lines...

In the presence of rising carbon concentrations more attention should be given to the role of the oceans as a sink for atmospheric carbon. We do so by setting up a simple dynamic global carbon cycle model with two reservoirs containing atmosphere and two ocean layers. The net flux between these...

Quantitative models for climate policy modeling differ in the production structure used and in the sizes of the elasticities of substitution. The empirical foundation for both is generally lacking. This paper estimates the parameters of two-level CES production functions with capital, labour and...

Genetic resources are living organisms that contain genetic information which is of importance for biotechnological research and development. Facing an accelerated worldwide loss in species diversity, the question is whether commercial trade with genetic resources can generate sufficient...

Do the sovereign wealth funds of Kazakhstan and Azerbaijan promote the sustainable use of government oil revenues? We review the operational rules and performance of the two funds and compare them to Norway’s Government Pension Fund Global. The key challenges are to stabilize government...
