Modelling Production Risk in Small Scale Subsistence Agriculture

Asche, Frank; Guttormsen, Atle G.; Roll, Kristin H. - 2006

In this paper we are investigating how production risk may influence the way a risk averse producer like a subsistence farmer chooses optimal input levels. Risk averse producers will take into account both the mean and the variance of output, and therefore we expect them to choose input levels...

HOW MUCH DO FARMERS VALUE THEIR INDEPENDENCE? ESTIMATING THE RISK AND AUTONOMY PREMIA ASSOCIATED WITH PRODUCTION CONTRACTS

Key, Nigel D. - 2002

A farmer's decision to contract or produce independently depends on the distribution of income under both arrangements, and on attributes associated with both business arrangements. Risk-averse farmers should be willing to pay a risk premium for the reduction in price risk provided by a...
