Abstract [en]

The individual farmer in a developing country has little incentive to care about the public good properties of on-farm biodiversity in the form of different crop varieties. There is a common assumption that because of this, farmers will tend to maintain too little biodiversity on their farms. However, this does not fit well with the empirical data; because of poorly functioning insurance markets, farms tend to maintain a wide range of different crop varieties in practice in order to hedge against weather shocks and other uncertainty. In this paper we develop a theoretical model to account for this, and show that farmers may in fact even maintain too much biodiversity on the individual farm, compared to the social optimum. This will be illustrated with empirical estimations from Ethiopian agriculture.
