We analyze the non-pecuniary aspects of some crop biotechnologies taken from three farm-level surveys. We focus particularly on the phenomen on of part-whole bias, which is the empirical finding that the sum of the stated part-worths (the value of each nonpecuniary characteristic) is greater...

The debate about the "quasi" moratorium on the release of GMOs in the European Union is on going. One of the major arguments that were put forward to delay the release of new traits was the one for more information. In this contribution we compare the situation for Bt-maize from the 1995 and...

The study analyzes ex-ante the adoption of insect resistant Bt eggplant in India. Farmers' willingness to pay (WTP) is estimated using the contingent valuation method. Given the economic importance of insect pests, the average WTP for proprietary Bt hybrids is more than four times the current...

A serious concern has been raised recently on the long run sustainability of the productivity effects of Green Revolution technologies in the light of decelerating trend in the yield growth of rice since the mid 1980s under irrigated ecosystem. However, the changes in physical yield are not true...

Surveys on consumer acceptance of GM foods revealed differences in knowledge, risk perception and acceptance of GM foods in Japan, Norway, Spain, Taiwan and the United States. There were opponents and proponents of GM foods. However, even in the United States, one of the most supportive...

Increase in agricultural productivity is induced by public investment in research. Several studies have analyzed the impact of research investment at the national level but such analyses at the state or regional level are a few. The present study is an attempt to analyze the pattern and quantify...

The only commercial genetically modified (GM) subsistence food crop is white maize in South Africa, which was released in 2001/2. This paper reports on the performance of insect resistant (Bt) white maize grown by smallholders in Hlabisa, KwaZulu Natal, where the other development is minimum...

Economic analysis of chemical pesticide use has shown that the interactions between plants, pests, damage control technology and state of the ecosystem are important variables to be considered. Hence, a bio-economic model was developed for the assessment of Bt variety and pesticide-based control...

This paper analyzes changes in U.S. agricultural technology during 1960-1999, emphasizing the role of immigrant workers on farm mechanization. The rates and directions of biased technological change based on the induced innovation theory are compared before and after the passage of the...

The allocation of benefits from research and development of new herbicide uses is dependent on patent status. The agricultural chemical industry will preferentially invest in herbicide R&D that increases the use of on-patent herbicides from which a company can capture a price premium. The...
