Kuhn’s Theorem shows that extensive games with perfect recall can equivalently be analyzed using mixed or behavioral strategies, as long as players are expected utility maximizers. This note constructs an example that illustrates the limits of Kuhn’s Theorem in an environment with ambiguity averse players who use a maxmin decision rule and full Bayesian updating.

The large galaxies in the Local Group, while all disk galaxies, have diverse stellar populations. A better understanding of these differences, and a physical understanding of the causes, requires more detailed study of the older populations. This presents a significant challenge to GAIA but the scientific returns are also significant.

Hypothesis testing is an important activity of empirical research and evidence-based medicine. A well worked up hypothesis is half the answer to the research question. For this, both knowledge of the subject derived from extensive review of the literature and working knowledge of basic statistical concepts are desirable. The present paper discusses the methods of working up a good hypothesis an...

Human affiliation with nonhuman nature is an important dimension of environmental concern and support for pro-environmental attitudes. A significant theory of human connectedness with nature, the Biophilia Hypothesis, suggests that there exists a genetically based inclination for human affiliation with the biological world. Both support and challenge to the Biophilia Hypothesis are abundant in ...

Protein classification can be performed by representing 3-D protein structures by graphs and then classifying the corresponding graphs. One effective way to classify such graphs is to use frequent subgraph patterns as features; however, the effectiveness of using subgraph patterns in graph classification is often hampered by the large search space of subgraph patterns. In this paper, the author...

We find a necessary and sufficient condition for ex-ante trade when agents are non-expected utility maximizers. The condition is that they share subjective beliefs. Our result holds for a class of convex preferences that contains many functional forms used in applications. In a special case of expected utility, the condition becomes exactly the common prior assumption. It can also be articulate...

I consider a model of directed search in which strategic sellers advertise general trading mechanisms. A mechanism determines the number of buyers that will get served and the side payments as a function of ex post realized demand. After observing these advertisements buyers simultaneously visit exactly one seller. Each buyer’s expected utility depends on the visiting decisions of other buyers....
