Tests for the role of risk aversion on input use

For risk-averting agents, risks alter production decisions while the existence of institutions to insure against adverse states of nature will likely restore decisions toward levels under risk neutrality. In this article, conditions are identified on a stochastic technology to test H-0,less than or equal to(rn): that risk averters choose smaller input levels than risk neutral agents, and H-0,less than or equal to(ra): that an increase in risk aversion reduces input use. A robust statistical method to test for dominance is adapted to stochastic production relations. It is found that H-0,less than or equal to(rn) is likely true for nitrogen application on Iowa corn. Weaker evidence is found in favor of H-0,less than or equal to(rn).
