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...

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 investigate why governments restrict exports of exotic raw materials taking rare earth elements as a case study. Trade restrictions on exotic materials do not have immediate macroeconomic effects. Relocating rare earth intensive industries is found to be the main reason behind China's export...

Der deutsche Strommarkt ist im Umbruch. Strom aus erneuerbaren Quellen verdrängt solchen aus konventioneller Erzeugung. Die bestehende Marktordnung fördert zwar effektiv den Ausbau der erneuerbaren Elektrizitätserzeugung, geht aber mit hohen Kosten einher. Zudem entstehen regionale...

One of the most promising ways of meeting climate policy targets is improving energy efficiency, i.e. reducing the amount of scarce and polluting resources needed to produce a given quantity of output. This study undertakes an empirical exercise using the World Input-Output Database (WIOD), a...

The amount of materials used worldwide in production and consumption increased by 56% 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 dataset...

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....

Der deutsche Strommarkt ist im Umbruch. Strom aus erneuerbaren Quellen verdrängt solchen aus konventioneller Erzeugung. Gleichzeitig wird immer mehr Elektrizität im Norden Deutschlands produziert und muss zu den Verbrauchern im Süden transportiert werden. Die bestehende Marktordung fordert...

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...
