Breeding can result in more output per unit of inputs as well as improved quality of outputs. A genetic-based technical change component is introduced into the Malmquist index, and productivity growth due to genetic and nongenetic factors is estimated for Icelandic dairy farms with quality...

This paper assesses the impact of chicken vaccination on farmers’ income. A dynamic simulation model, VIPOSIM, combined with benefit-cost techniques, was used ensuring that both, the dynamic aspects of village poultry production system and selection bias are addressed. The findings of this...

The paper develops a composite index of GMO standards restrictiveness for 60 countries, assigning objective scores to six different regulatory dimensions. Using this index and its components, we empirically investigate the political and economic determinants of GMO regulations. Results show that...

Data from a farm survey and choice experiment are used to value the benefits of Bt cotton in Pakistan. Unlike previous research on the economic impacts of Bt, which mostly concentrated on financial benefits in terms of gross margins, we also quantify and monetize positive externalities...

Crop residue use for soil mulch and animal feed are the two major competing purposes and the basic source of fundamental challenge in conservation agriculture (CA) where residue retention on farm plots is one of the three CA principles. Using survey data from Kenya and applying bivariate ordered...

The aim of this paper is to estimate the perennial crop potential regarding new uses like second generation biofuels. We focus on the introduction of a perennial yearly harvested crop, namely the miscanthus, in European agricultural short term supply model - AROPAj. Inserting this crop in the...

The high agricultural process of the Argentine humid pampas forces the intensification and relocation of cattle and dairy systems into subhumid and semiarid region to keep their competitiveness. In consequence, there is an increasing water demand scenario in these fragile areas in relation with...

We analyze complicated ethanol/commodity policies not just in (q, p) space, but also in “policy space” and “welfare space.” Specific advantages of conducting policy analysis in welfare and policy spaces are (1) it makes clearer the distributional consequences of policy change instead of...

During the last fifteen years, the impressive increase in the area planted with soybeans in Argentina, since the commercial release of glyphosate-tolerant varieties in 1996, has sparked a heated debate about its implications. There is wide concern about the detrimental effects of this process,...
