A stochastic dynamic model was constructed to analyze investment decisions of an individual farmer under risk in the presence of irreversibilities, embedded technical change and indivisible capital. An analytical solution was obtained and its local behavior studied by numerical methods. Optimal...

This paper explores the effect of commercial farmers-academic researchers linkages on research productivity in fields related to agriculture. Using original data and econometric analysis, our findings show a positive and significant relationship between intensive linkages with a small number of...

A growing body of literature is focusing on how the collaborations researchers engage in affect their productivity. Most authors have focused on linkages among academic researchers, measuring productivity by the number of papers published in ISI journals. In contrast, the impact of interactions...

The depreciation rate for capital assets may have endogenous and exogenous components. Change in the exogenous component depends on technological change and/or environmental factors, shifts the production function, and independently affects profitability and investment. Change in the endogenous...

In the 1990s, no-till with mulch, a sustainable agricultural alternative, was introduced to Ghanaian farmers through a joint program between the Crops Research Institute in Kusami, Ghana, Sasakawa Global 2000, and the Monsanto Company. The package was disseminated to farmers in the Forest,...

"Agricultural advisory services play an important role in supporting the use of the agricultural sector as an engine of pro-poor growth and enabling small farmers to meet new challenges, such as accessing export markets, adopting environmentally sustainable production techniques, and coping with...

En la d�cada del 90, el sector agropecuario mexicano gener� alrededor del 5% del PBI y el 2.5% de las exportaciones. A pesar de su reducida contribuci�n al PBI, el sector agropecuario tiene una gran importancia econ�mica y social como generador de empleos (un 25% del empleo total), por...
