We scrutinize the impact of international productivity gains (spillovers) induced by imports and exports on optimal tariffs. Our research question reads: how do trade-induced international productivity gains influence the choice of the optimal tariff? Trade-induced international technology...

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...

A diverse set of tools has been developed in Industrial Ecology to tackle the problems caused by human economic activity. These instruments include Life Cycle Assessment (LCA) and Material Flow Analysis (MFA). Especially LCA is now increasingly used in policy making. Design and Evaluation of...

The German electricity market is changing fundamentally as renewable energy replaces conventional sources. Simultaneously, regional imbalances between generation and consumption are appearing. The authors sketch a new market design for the German electricity market, jointly taking into account...

Compared to oil and gas, metals have been rather a side issue in the economic analysis of natural resources in the last decades. However, in the recent past we saw an increase of interest in the topic, mainly driven by the heated discussion about critical metals. Rare Earth Elements (REE) are...

Rare Earths are a group of 17 metals which were presumably unknown to the vast majority of people until very recently. The combination of growing demand and tightened export restriction by China, which holds almost monopolistic power in their supply, has led to massive price increase in 2011....

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...

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 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...
