The impact of uncertain salt balances in irrigate fields is assessed with a hydroeconomic model that incorporates the effects of salinity. Uncertainty in two parameters that jointly determine root zone salinity is investigated and the conclusions prove to depend upon the way in which these...

The well-known Allais paradox is reformulated as a daily farm decision problem. Only 26% of the farmers exhibit violations of the expected utility hypothesis. Moreover, the tendency for violation decreases with the farm operator's education, experience and family size. No effects of the farm...
