Millions of small farmers are reached commercially every day as they buy seeds and crop protection products, fertiliser, cell phones, machinery and tools, taking advantage of the science and research embodied in these products. The market for agricultural inputs is large, and the role of the...

We estimate the causal impact of the EU Emissions Trading Scheme on manufacturing firms using comprehensive panel data from the German production census. Semiparametric matching estimators yield robust evidence that the policy caused treated firms to abate one fifth of their CO2 emissions...

The purpose of extension is to disseminate advice to farmers. Knowledge gaps contribute to yield gaps. Services and quality inputs are essential productivity-enhancing tools. However, their optimum use requires knowledge. Farmers also need information on prices and markets, post-harvest...

Night lights could be a valuable proxy of economic activity at the subnational level when GDP data are lacking or of poor quality. Supplementing Henderson et al.'s (2012) analysis at the national level, we assess the stability of the elasticity of GDP with regard to night lights across regions...

The contribution of biofuels to the saving of greenhouse gas (GHG) emissions has recently been questioned because of emissions resulting from land use change (LUC) for the bioenergy feedstock production. We investigate how an expanding biofuel feedstock production impacts on land use dynamics if...
