| This study examines media coverage of genetically modified (GM) crops in a risk communication framework. Content analysis is employed to investigate how specific environmental, food safety, and landmark events, such as the monarch butterfly and Pusztai controversies, and the cloning of Dolly-the-sheep, were reported by the media. Media coverage is from United Kingdom and United States newspapers over the period 1990 through 2001. On balance, findings show that the UK press has been more negative than the U.S. press in its coverage of GM crops. In addition, environmental and food safety events had a significant impact on the level and cycle of GM crop coverage. |

| The U.S. appears committed to the ongoing use of ethanol biofuels. In order to realize the desired benefits, ethanol production must continue to become more efficient. Although many technologies have emerged to improve efficiency this article focuses on the role that corn biotechnology might play. Biotechnology offers the potential to increase yields and lower input use as well as aid the conversion of corn to ethanol. This could have a meaningful impact on the energy balance and greenhouse gas emissions of ethanol production. This article finds those impacts to be significant, although likely to be eclipsed by cellulosic biofuels. However, the realization of any such benefits is conditioned by prevailing market and policy conditions. In a world where the... |

| By most measures, adoption of first generation crop biotechnologies in the United States and elsewhere has been extremely fast. Yet, only modest research effort has been devoted to understanding why producers in different parts of the world have adopted these technologies at such rapid rates. In this paper, we analyze producer decisions on whether to adopt three separate cotton biotechnologies in the US and to what extent. We find that US cotton producers tend to choose bundles of conventional technologies, agrobiotechnologies and relevant agronomic practices out of many possible ones. Hence, their behavior is characterized by multiple simultaneous and interdependent adoption decisions. Furthermore, US cotton producers partially adopt one or more of the... |

| In this study it is argued that conflicting empirical results on the relationship between technical efficiency and education may be in part attributed to difficulties in the measurement of key variables. Calculation of technical efficiency with three alternative frontier methods for a sample of Guatemalan corn farms resulted in significant differences both in the average technical efficiency of the sample and the efficiency rankings of individual farms. Furthermore, following two-step procedures where technical efficiency is regressed against a set of explanatory variables, it is shown that the choice of efficiency measurement technique can alter the importance of education as a contributing factor to increased technical efficiency. An alternative... |

| The question in the title is divided into: (1) Can we trade the current generation of products from biotech or the technology itself? and (2) Can we trade the future generations of products of the technology? Controversy over the first generation of products has resulted in international trade being segmented into two markets: GMO-free and GMO. The first market is supported by voluntary labelling, making mandatory labelling largely unnecessary. While trade flows have been rearranged, markets have been little affected. We conclude that trade in the future generation will be dominated by capital and technology flows, with production for local markets dominating product trade flows. |

| In 1998 the European Union placed a moratorium on the planting of transgenic crops within its borders. The resulting ban on biotech crops has led to the current trans-Atlantic trade dispute between the United States and the EU. At the heart of this dispute is the issue of consumer acceptance. The EU’s current position is predicated on perceived public concerns about biotech foods which found a voice in numerous opinion polls conducted during the late 1990s (e.g., European Commission, 1997, 2000). Such concerns have also been amplified by intense media coverage and resulting political activism. Given the pivotal role that consumer opinion has played in recent EU policy, an understanding of how consumers value biotech foods is critical to informed... |
