| Resumen: |
In the December 2014 issue of Environment and Development Economics, we published the article, ’The economic power of the Golden Rice opposition’ by Wesseler and Zilberman. The paper generated substantial interest, not only in academia but also among civil society groups. In this note, we address some of the concerns that have been raised about our results. Our main conclusion remains that misguided regulations in the case of Golden Rice have cost millions of healthy life years and billions of dollars. |

| Resumen: |
The introduction and adoption of new technologies is an important component of development projects. Many technologies that could spur considerable increase in welfare, however, are often adopted at low rates even when donors and NGOs have invested their effort in them heavily. This paper develops a framework to analyze inefficiencies caused by fit-risk (potential users are not certain whether the technology will fit their needs, lifestyles, social feedback or capabilities), and the role of marketing tools, such as demonstration, in reducing fit-risk and enhancing the efficiency of development projects. We find that, in the presence of fit-risk, there is always unrealized demand and resource waste. Donors who ignore fit-risk always overestimate the project value and over-subsidize the products they are promoting. We identify conditions under which introducing demonstration may help alleviate fit-risk and improve the overall project values. The impact of eliminating fit-risk on the project uptake depends on the probability of fit. |

The impacts and acceptance of agricultural biotechnology: an introduction to the special issue |

| Resumen: |
Attitudes towards and acceptance of agricultural biotechnology, which involves inserting genes that carry new traits into existing varieties, has been subject to much debate. This special issue aims to address several gaps in the literature on genetically modified (GM) technology in agriculture. Some of the papers in the issue address the economic and health aspects of genetic modification in agriculture while others examine consumers’ attitudes towards GM products, and the marketing and labeling of GM products. |

| Resumen: |
We use aggregate data to estimate supply, price, land-use, and greenhouse gas impacts of genetically engineered (GE) seed adoption due both to increased yield per hectare (intensive margin) and increased planted area (extensive margin). An adoption model with profitability and risk considerations distinguishes between the two margins, where the intensive margin results from direct ’gene’ impacts and higher complimentary input use, and the extensive margin reflects the growing range of lands that become profitable with the GE technology. We identify yield increases from cross-country time series variation in GE adoption share within the main GE crops - cotton, corn and soybeans. We find that GE increased yields 34 per cent for cotton, 12 per cent for corn and 3 per cent for soybeans. We then estimate the quantity of extensive margin lands from year-to-year changes in traditional and GE planted area. If all production on the extensive margin is attributed to GE technology, the supply effect of GE increases from 5 per cent to 12 per cent for corn, 15 per cent to 20 per cent for cotton, and 2 per cent to 40 per cent for soybeans, generating significant downward pressure on prices. Finally, we compute ’saved’ lands and greenhouse gases as the difference between observed hectarage per crop and counterfactual hectarage needed to generate the same output without the yield boost from GE. We find that altogether, GE saved 13 million hectares of land from conversion to agriculture in 2010, and averted emissions are equivalent to roughly one-eighth of the annual emissions from automobiles in the US. |

| Resumen: |
Vitamin A enriched rice (Golden Rice) is a cost-efficient solution that can substantially reduce health costs. Despite Golden Rice being available since early 2000, this rice has not been introduced in any country. Governments must perceive additional costs that overcompensate the benefits of the technology to explain the delay in approval. We develop a real option model including irreversibility and uncertainty about perceived costs and arrival of new information to explain a delay in approval. The model has been applied to the case of India. Results show the annual perceived costs have to be at least US$199 million per year approximately for the last decade to explain the delay in approval of the technology. This is an indicator of the economic power of the opposition towards Golden Rice resulting in about 1.4 million life years lost over the past decade in India. |
