We estimate the impact of climate change on agricultural production in a panel of 127 countries from 1961 to 2002. In contrast to the existing literature we account for cross-sectional dependence and technology heterogeneity. We find no significant impact of climate change on agricultural...

This paper provides a model-based assessment of local and global climate change impacts for the case of Yemen, focusing on agricultural production, household incomes and food security. Global climate change is mainly transmitted through rising world food prices. Our simulation results suggest...

This paper introduces the concept of homogeneous non-causality in heterogeneous panels. This concept is used to examine a panel of data for evidence of a causal relationship between GDP and carbon emissions. The technique is compared to the standard test for homogeneous non-causality in...

This paper provides some evidence on the existence of the wage curve - the negative relationship between individual wages and the local unemployment rate - within a number of occupations. It exploits the Bank of Italy's Household Survey and draws data from 1977 to 2008. An occupation-level wage...

The paper discusses the decisions on the reform of the CAP from June 2003. The decisions focus on the decoupling of the direct payments to farmers from production. This will reduce production incentives and thereby improve the allocation of resources. However, payments to farmers will hardly be...

The paper discusses the decisions on the CAP in the context of the Berlin summit. In a rather broad perspective the agricultural sectoral and related objectives are analyzed for their consistency and compatability with higher ranking societal objectives. The policiesÂ’ allocational and...

In the context of energy security and climate protection, biomass is given high importance. Nevertheless, land-use conflicts resulting from the cultivation of biomass and their economy-wide effects are yet to be fully understood. To shed light on this issue we link three distinctive models; a...

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...

This paper explores the interrelations between economic growth, international trade and environmental degradation both theoretically and empirically. Panel data from developed and developing countries for the period of 1980 to 2003 is used and previous critique, especially on the econometric...

Large-scale agricultural land acquisitions might entail substantial welfare implications for the affected rural population. Whether the impacts are indeed as devastating as the popular notion of "land grabs" would suggest depends on a number of factors, including the size of compensation...
