By introducing proper pricing instruments, farm level water can be used more efficient. But it demands a proper estimation strategy to analyse the efficiency and the input use behavior of farms under the new pricing system. As most production relationships are stochastic in nature, excluding...

We consider an economy where individuals privately choose effort and trade competitively priced securities that pay off with effort-determined probability. We show that if insurance against a negative shock is sufficiently incomplete, then standard functional form restrictions ensure that...

We consider an economy with incomplete markets and a single firm and assume that utility can be freely transferred in the form of the initially available good 0 (quasilinearity). In this particularly simple and transparent framework, the objective of a firm can be defined as the maximization of...
