Supermarkets are gaining ground in the agri-food systems of many developing countries. While recent research has analyzed income effects in the small farm sector, impacts on productivity and efficiency have hardly been studied. We use a meta-frontier approach and combine this with propensity...

Since the work of FEENSTRA (2002), the standard ANDERSON & VAN WINCOOP (2003) Gravity Model has been estimated using a fixed effects approach. However, a fixed effects approach has a major drawback: it does not allow for the estimation of exporter- and importer-invariant variables. Thus,...

Adopting a gravity framework and using data from 2010 to 2012 for 74 countries, we investigate whether the intensity of GlobalGAP standard adoption has a positive impact on EU banana import values. Intensity is measured by using number of GlobalGAP certified producers and hectares harvested...

GlobalGAP is an important private standard in food sector. However, geographic diffusion of GlobalGAP is uneven across the world. We use a panel from 2008 to 2012 for 170 FAO member countries to analyze GlobalGAP diffusion in the agricultural sector as a whole as well as in the crops subsector....

Options trading is increasingly important in more volatile agricultural markets. Options allow for unilateral hedging of price risks, e. g. against falling prices only, and are an indispensable risk management instrument for farmers and grain dealers. Concerns that soaring options trading could...

We examine the impact of two important non-tariff measures presumed to simultaneously affect firms' decisions to export to the European Union (EU). As a novelty to the literature, we analyse the impacts of EU pesticide standards on African exports alongside a complementary non-tariff measure in...

EFForTS is a collaborative research center (CRC) which focuses on Ecological and socioeconomic Functions of Tropical Lowland Rainforest Transformation Systems in Sumatra,Indonesia. The paper presents the common sampling frame of the socio economic sub-projects.The investigations and data...

In Indonesia the agricultural sector plays a key role for broad based economic development in rural areas. Rubber is one of the most important crops, and Indonesia is the second largest producer in the world. However, a high level of concentration in the processing industry limits the spread of...
