The traditional trade theory predicts that trade in goods perfectly substitutes for direct movement of factors. This equivalence between goods trade and factor movements, however, depends crucially on assumptions about the production. This paper establishes necessary and sufficient conditions...

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...

Climate change affects the physical and biological system in many regions of the world. The extent to which human systems will suffer economically from climate change depends on the adaptive capabilities within a region as well as across regions. We use an economic General-Equilibrium model and...

The DART model is a multi-sectoral, multi-regional dynamic computable general equilibrium model of the world developed for the analysis of international climate policies. Since the first version of DART was developed at the Kiel Institute for World Economics in 1998, the model has undergone a...

The issue of global warming has become a major topic in the international environmental debate. Alternative climate policy measures can be evaluated with the help of a simulation model that integrates economic and natural science considerations. A fully integrated assessment of the two-way...

This paper examines how trade liberalization affects the innovation incentives of firms, and what this implies for industry productivity and social welfare. For this purpose we develop a reciprocal dumping model of international trade with heterogeneous firms and endogenous R&D. We identify two...

This paper discusses the gains from foreign direct investment (FDI) in a two country setting with endogenous markets structures under two alternative locations for the oligopolistic industry. If the oligopolistic industry is located in the domestic country only, we show that market concentration...
