Although the benefits of genetically modified (GM) crops have been well documented, how do farmers manage the risk of new technology in the early stages of technology adoption has received less attention. We compare the total factor productivity (TFP) of cotton to other major crops (wheat, rice,...

This paper considers the impact of an agricultural extension program, The Özyeğin Rural Development Program, implemented in eastern Turkey, on rates of agricultural technology adoption. Using a uniquely designed experimental panel survey collected in treatment and control villages before and...

The paper examines effects of agricultural extension on crop yields in Kenya controlling for other determinants of yields, notably the schooling of farmers and agro-ecological characteristics of arable land. The data we use were collected by the Government of Kenya in 1982 and 1990, but the...

The intellectual property system does not seem to drive the rate of innovation in the market for vegetable varieties. Drawing on a unique data set of all plant patents, plant variety protection certificates, and utility patents among 42 vegetable varieties, this short paper examines the...

Do transgenic crops cause agrobiodiversity erosion? We hypothesize that they increase productivity and reduce production risk and may therefore reduce farmer demand for on-farm varietal diversity, especially when only a few transgenic varieties are available. We also hypothesize that varietal...

The study focused on increasing crop output through improved technology adoption: the Fadama III approach in Delta State, Nigeria. The study which took place between June 2012 and February, 2013 used stratified random sampling technique to select 340 respondents (made up of 279 Fadama users and...
