The extent to which people are willing to take on risk, i.e. their risk preferences as well as subjective risk perception plays a major role in explaining their behavior. This is of particular relevance in agricultural production, which is inherently risky. The data presented here was collected amongst a total of 64 German farmers in 2015. It includes results of three different risk preference ...

We present a model for scheduling power generation at a wind farm, and introduce a particle swarm optimization algorithm with a small world network structure to solve the model. The solution generated by the algorithm defines the operational status of wind turbines for a scheduling horizon selected by a decision maker. Different operational scenarios are constructed based on time series data of...

We study incentives for information sharing among agricultural intermediaries in imperfectly competitive markets for farm output. Information sharing always increases expected grower and total surplus, but may reduce expected intermediary profits. Even when expected profits increase with information sharing, intermediary firms face a Prisoner’s Dilemma where it is privately rational to withhold...

This paper addresses the problem of determining the sale price and the production quantity under supply uncertainty. The problem is commonly observed in the agricultural industry. We consider a firm that initially leases farm space in order to grow fruit. The realized amount of fruit supply fluctuates due to weather conditions, diseases, etc. At the end of the growing season, the firm makes two...

Do employers substitute adults for children, or do they treat them as complements? Using data from a Mexican schooling experiment, I find that decreasing child farm work is accompanied by increasing adult labor demand. This increase was not caused by treatment money reaching farm employers: there were no significant increases in harvest prices and quantities, non-labor inputs, or non-farm labor...
