A general theoretical and empirical framework is developed for assessing the potential of a vertically integrated firm to foreclose downstream competitors. Using this framework a policymaker may also evaluate the empirical welfare effects from a vertically integrated firm raising rivals' costs....

The Renewable-Energy-Source-Act (EEG) promotes German biogas production in order to substitute fossil fuels, protect the environment and prevent climate change. In this paper we quantitatively analyse the EEG-reform in 2008. Results imply that the reform contributes to an expansion of biogas...

We analyze optimal monetary policy when a central bank has to learn about an unknown coefficient that determines the effect of surprise inflation on aggregate demand. We derive the optimal policy under active learning and compare it to two limiting cases---certainty equivalence policy and...

The classical cobweb theorem is extended to include production lags and price forecasts. Price forecasting based on a longer period has a stabilizing effect on prices. Longer production lags do not necessarily lead to unstable prices; very long lags lead to cycles of constant amplitude. The...

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...

A simple model is used to illustrate the effects of a reduction in (marginal) abatement cost in a two country setting. It can be shown that a the country experiencing a cost reduction can actually be worse off. This holds true for a variety of quantity and price based emission policies. The most...

“Desert Power 2050” is probably the world’s most ambitious strategy report towards the decarbonization of the power sector in Europe, the Middle East and North Africa (EUMENA). The report inspired by the Desertec vision aims at providing clean energy from MENA’s desert regions to the...

In this paper, a real-financial CGE model is employed for Bolivia to simulate the macroeconomic and distributional effects of exchange rate policy in a highly dollarized economy. Overall, dollarization appears to matter more through real than through financial-sector effects. The main...

In order to reach the two degree target it is necessary to control CO2 emissions also in fast growing emerging economies such as India. The question is how the Indian economy would be affected by e.g. including the country into an international climate regime. Existing analyses with either a...

In order to estimate the economic costs of climate change for Tunisia, this paper uses a combination of biophysical and economic models. In addition, the paper draws on the literature to complement the quantitative analysis with policy recommendations on how to adapt to the changing climate. The...
