Given a utility defined on a Hilbert outcome space, we define at each outcome a generalized Arrow-Pratt (GAP) coefficient belonging to the Hilbert space. Comparing the risk aversion of such utilities using their GAP coefficients is equivalent to doing so in terms of other standard,...

We study a model for evaluating an organisation’s design wherein its principal (a) delegates outcome-determining tasks to agents with heterogeneous preferences, (b) guides their performance of these tasks via action recommendations, and (c) is better informed than the agents about the state of...

The central results of this paper are dualities between actions in a decision problem that are not strongly (resp., weakly) dominated over a state space and actions that are best (resp., internal-best) replies to a state. These results hold for action and state spaces that are subsets of...

We consider organizations with a single principal and many agents who interact in an environment with the following features -- (a) Nature im-perfectly informs the principal via a state-contingent signal, but not the agents, about the state of the world, (b) the principal selectively shares this...

We study an incomplete information, non-cooperative model of the determination of national emission endowments under a Kyoto type protocol with heterogeneous nations. The model generates a link between national types and equilibrium na-tional emission caps. We analyze this link to (a) derive the...

We model the interaction between a regulator and a polluting firm in the optimal mechanism design setting. The particular aspect of the interaction that we model is the regulator's problem of providing incentives to induce optimal adoption of pollution processing technology by the firm, subject...

The Author considera a decision-making environment with an outcome space that is a convex and compact subset of a vector space belonging to a general class of such spaces. Given this outcome space,he defines general classes of (a) risk averse von Neumann-Morgenstern utility functions defined...

Pratt (1964) and Yaari (1969) contain the classical results pertaining to the equivalence of various notions of comparative risk aversion of von Neumann-Morgenstern utilities in the setting with real-valued outcomes. Some of these results have been extended to the setting with outcomes in n ....

We consider a decision-making environment with an outcome space that is a convex and compact subset of a vector space belonging to a general class of such spaces. Given this outcome space, we de¯ne gen- eral classes of (a) risk averse von Neumann-Morgenstern utility func- tions de¯ned over the...

This paper studies an incompletely informed regulator's problem of inducing a firm producing durable pollution to adopt a socially optimal pollution storage technology. We construct a sparse, yet flexible, theoretical model that can be applied directly to concrete situations as it is stated...
