内容简介： We develop a nonparametric and ordinal approach for testing pure strategy Nash equilibrium play in games with monotone best responses, such as those with strategic complements/substitutes. The approach makes minimal assumptions on unobserved heterogeneity, requires no parametric assumptions on payoff functions, and no restriction on equilibrium selection from multiple equilibria. The approach can also be extended in order to make inferences and predictions. Both model-testing and inference can be implemented by a tractable computation procedure based on column generation. To illustrate how our approach works, we include an application to an IO entry game.

演讲人简介：John K.-H. Quah (柯金浩) is a Distinguished Professor at the National University of Singapore.

His recent research includes nonparametric analysis of monotone choice, Allais paradox, and bounded rationality. John has published in the American Economic Review, Econometrica, the Journal of Political Economy and the Review of Economic Studies, and is a Fellow of the Econometric Society. He is also an associate editor at Theoretical Economics, an advisory editor at Journal of Mathematical Economics, and a co-editor at Economic Theory.
