Inference on Optimal Treatment Assignments

Armstrong, Timothy B.; Shen, Shu - Cowles Foundation for Research in Economics, Yale University - 2013

We consider inference on optimal treatment assignments. Our methods allow for inference on the treatment assignment rule that would be optimal given knowledge of the population treatment effect in a general setting. The procedure uses multiple hypothesis testing methods to determine a subset of...

Testing Linearity Using Power Transforms of Regressors

Baek, Yae In; Cho, Jin Seo; Phillips, Peter C.B. - Cowles Foundation for Research in Economics, Yale University - 2013

We develop a method of testing linearity using power transforms of regressors, allowing for stationary processes and time trends. The linear model is a simplifying hypothesis that derives from the power transform model in three different ways, each producing its own identification problem. We...

Generic Results for Establishing the Asymptotic Size of Confidence Sets and Tests

Andrews, Donald W.K.; Cheng, Xu; Guggenberger, Patrik - Cowles Foundation for Research in Economics, Yale University - 2011

This paper provides a set of results that can be used to establish the asymptotic size and/or similarity in a uniform sense of confidence sets and tests. The results are generic in that they can be applied to a broad range of problems. They are most useful in scenarios where the pointwise...

Meritocracy Voting: Measuring the Unmeasurable

Phillips, Peter C.B. - Cowles Foundation for Research in Economics, Yale University - 2011

Learned societies commonly carry out selection processes to add new fellows to an existing fellowship. Criteria vary across societies but are typically based on subjective judgments concerning the merit of individuals who are nominated for fellowships. These subjective assessments may be made by...

Testing Equality of Covariance Matrices via Pythagorean Means

Cho, Jin Seo; Phillips, Peter C.B. - Cowles Foundation for Research in Economics, Yale University

We provide a new test for equality of covariance matrices that leads to a convenient mechanism for testing specification using the information matrix equality. The test relies on a new characterization of equality between two k dimensional positive-definite matrices A and B: the traces of...

The Strategic Impact of Higher-Order Beliefs

Chen, Yi-Chun; Tillio, Alfredo Di; Faingold, Eduardo; … - Cowles Foundation for Research in Economics, Yale University - 2012

severity of this robustness problem by characterizing conditions on the primitives of the model -- the players’ hierarchies of …) in terms of beliefs. We apply our characterizations to a variety of questions concerning robustness to perturbations of … higher-order beliefs, including genericity of common priors, and the connections between robustness of strategic behavior and …

Robust Monopoly Pricing

Bergemann, Dirk; Schlag, Karl - Cowles Foundation for Research in Economics, Yale University - 2005

We consider a robust version of the classic problem of optimal monopoly pricing with incomplete information. In the robust version of the problem the seller only knows that demand will be in a neighborhood of a given model distribution. We characterize the optimal pricing policy under two...

Robust Implementation in General Mechanisms

Bergemann, Dirk; Morris, Stephen - Cowles Foundation for Research in Economics, Yale University - 2008

A social choice function is robustly implemented if every equilibrium on every type space achieves outcomes consistent with it. We identify a robust monotonicity condition that is necessary and (with mild extra assumptions) sufficient for robust implementation. Robust monotonicity is strictly...
