Abstract

Using data from Bolivia, this paper analyzes seed market participation and how transaction costs in these markets influence intracrop biodiversity and the influence of biodiversity on yields. Results indicate that seed market attributes such as distance and market-level biodiversity have a crucial effect on a farmer's market choice, suggesting that farmers are willing to sacrifice time and income to travel further distances in order to reach markets with a broader range of varieties. This study finds that farmers from this sample who have access to seed markets are more likely to have higher levels of intracrop biodiversity. In addition, for market-integrated farmers, intracrop biodiversity does not seem to have a negative effect on yields, which suggests that improved market access does not threaten biodiversity in contexts with similar characteristics to the study site.
