Chambers and Quiggin, claim that the state-contingent approach provides the best way to think about all problems in the economics of un- certainty, including problems of consumer choice, the theory of the firm, and principal?agent relationships. The purpose of this paper is to restate this...

In a stochastic decision environment, differences in information can lead rational decision makers facing the same stochastic technology and the same markets to make different production choices. Efficiency and productivity measurement in such a setting can be seriously and systematically biased...

This paper presents a dual representation of firm-level and market-level equilibrium behavior for a sole proprietorship economy with competitive and frictionless financial markets and stochastic production opportunities in a two-period setting. The dual equilibrium model is used to state...

Quiggin and Chambers have introduced the notion of invariant preferences, and shown that the only invariant expected-utility functionals are those associated with a quadratic utility function. This note identifies the class of preferences which simultaneously satisfy invariance, two-fund...

This paper has two goals. First,we demonstrate that standard arguments and methods from production and duality analysis can be used to provide a comprehensive and general treatment of the value of information for a risk-averse firm with expected-utility (linear-in-probabilities) preferences and...

In this paper, we generalize the model of Quiggin and Chambers (2004) to allow for ambiguity, and derive conditions, referred to as generalized invariance, under which a two argument representation of preferences may be obtained independent of the existence of a unique probability measure. The...

Separation results, as they are usually understood, refer to conditions under which a firm's production decisions are independent of its risk attitudes. Well-understood situations where separation occurs typically include those where technically feasible production opportunities are replicable...

In this paper, we consider the relationship between supermodularity and risk aversion. We show that supermodularity of the certainty equivalent implies that the certainty equivalent of any random variable is less than its mean. We also derive conditions under which supermodularity of the...

Insurance contracts are frequently modelled as principal--agent relationships. Although it is commonly assumed that the principal, in this case the insurer, has complete freedom to design the contract, the problem formulation in much of the principal--agent literature presumes that the contract...
