Within a context of trainer training, examines a powerful exercise to encourage trainers to reflect on their role and effectiveness within their organizations. Describes how participants are asked to draw a “picture” of the “ideal trainer”. Symbols, images and metaphors can be very...

The United States Supreme Court has long recognized compactness as an important principle in assessing the constitutionality of political districting plans. We propose a measure of compactness based on the distance between voters within the same district relative to the minimum distance...

We consider full implementation in complete-information environments when agents have an arbitrarily small preference for honesty. We offer a condition called separable punishment and show that when it holds and there are at least two agents, any social choice function can be implemented by a...

This paper characterizes the optimal way for a principal to structure a rank-order tournament in a moral hazard setting (as in Lazear and Rosen in J Polit Econ 89:841–864, 1981). We find that it is often optimal to give rewards to top performers that are smaller in magnitude than corresponding...

We analyze a rational-expectations model of price formation in an intermediate-good market under uncertainty. There is a continuum of firms, each consisting of a party who can reduce production cost and a party who can discover information about demand. Both parties can make specific investments...

We analyze a model of US presidential primary elections for a given party. There are two candidates, one of whom is a higher quality candidate. Voters reside in m different states and receive noisy private information about the identity of the superior candidate. States vote in some order, and...

We analyze a rational-expectations model of price formation in an intermediate-good market under uncertainty. There is a continuum of dyads, each consisting of an upstream party and a downstream party. Both parties can make specific investments at private cost, and there is a machine that either...

We develop a measure of compactness based on the distance between voters within the same district relative to the minimum distance achievable, which we coin the relative proximity index. Any compactness measure that satisfies three desirable properties (anonymity of voters, efficient clustering,...
