Large-scale agricultural investments (LSAIs) typically depend on strong formal institutions and market-oriented intensive farming, whereas informal institutions tend to characterize the traditional villages located around them. We investigate changes to social capital in such villages when LSAIs...

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...

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...

In dem Papier werden die Reformbeschlüsse zur europäischen Agrarpolitik vom Juni 2003 diskutiert. Im Mittelpunkt der Beschlüsse steht die Entkoppelung der Prämienzahlungen von der Produktion. Damit werden Produktionsanreize für die Landwirte abgebaut und es dürfte zu einer...

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 policies' allocational and...

Biogasproduktion wird in Deutschland mit dem Ziel des Klima- und Umweltschutzes sowie der Substitution fossiler Energieträger durch das Erneuerbare-Energien-Gesetz (EEG) gefördert. Dieser Beitrag analysiert quantitativ durch Kopplung eines Agrarsektor- und eines Standortmodells die...

In light of the surge in large-scale farms in developing countries, concerns have been raised that smallholders may be negatively affected. There is, however, very little evidence beyond case studies to support these claims. Drawing on nationally representative household data sets and an...

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...

Global food markets demand the adoption of food standards by small-scale farmers in developing countries when they enter international markets. While a conventional certification with GlobalGAP can be a market entry condition for conventional food, especially for horticultural products, organic...
