We scrutinize the impact of international productivity gains (spillovers) induced by imports and exports on optimal tariffs. First, we solve a stylized 2x2 trade model of a large open economy and show that (a) productivity gains via exports and imports both reduce the strategically optimal...

This report presents the Basic WIOD CGE model. The model represents the first implementation of the World Input-Output Database (WIOD) into the CGE framework and is tailored to provide a maximum fit with WIOD data. The model is specifically designed such that it can serve as the basis for...

This paper presents the METal ResOurces (METRO) model, a partial equilibrium model tailored for metal markets. It allows for a disaggregated representation of the mining sector and endogenous investment in extractive capacities. It can be calibrated to a large number of metal markets. Rare Earth...

This paper investigates China's capability to exert power on Rare Earth markets until 2020. A dynamic partial equilibrium model allowing for a disaggregated representation of the mining sector and endogenous investment in capacities is developed. The model is calibrated on a novel dataset on...

The amount of materials used worldwide in production and consumption increased by 56 per cent from 1995 to 2008. Using an index decomposition analysis based on the logarithmic mean divisia index, we investigate the drivers of material use, both on a global and a country scale. We exploit a panel...

This article presents an applied general equilibrium model which combines the theoretical foundations of an Eaton-Kortum type model of international trade with the complexity of a global multi-region, multi-sector Computable General Equilibrium (CGE) model of production and consumption. The...

Between 1990 and 2008, many industrializing countries have experienced tremendous economic growth, which coincided with a substantial increase in the use of materials. That poses the question how a continued economic convergence of developing nations will affect the use of biomass, fossil fuels,...

This study investigates the within-country heterogeneity of material footprints implied by households' consumption in Germany. Material footprints are defined as the amount of biomass, minerals, and fossil fuels extracted to produce the goods that households consume. Combining input-output data...

This article introduces an innovative and exible dynamic forward calibration method for disaggregated new quantitative trade models, particularly the Eaton and Kortum model, within a computable general equilibrium framework. The model is parameterized based on distinct, consistent future...

This article tries to increase public awareness of a crucial but rarely discussed global challenge by introducing a novel economic analysis: drawing on insights from various disciplines, it studies policies regulating sand extraction and trade. While sand is essential for construction and land...
