Debates on approaches to impact evaluation design appear to have reached an impasse in recent years. An objective of the international conference, Perspectives on Impact Evaluation, March 29th to April 2nd, Cairo, organized by 3ie, NONIE, AfrEA and UNICEF, was to bring together different voices...

This paper has three 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...

The paper utilizes duality theory to derive an exact representation of the core of a supermodular capacity for finite-state-space Choquet expected utility preferences. Using the dual representation we develop an algorithm that uses information on willingness to pay and willingness to sell to...

In this article, it is shown that a wide range of comparative statics results from expected utility theory can be extended to generalized expected utility models using the tools of supermodularity theory. In particular, a range of concepts of decreasing absolute risk aversion may be formulated...
