Abstract
We derive an econometric test for the presence of monotone comparative statics in models with multiple equilibria. The test applies to many economic models, such as single-person decision, industrial organization, macroeconomic and game-theory models. These models have complementarities between exogenous and endogenous variables. We show that, as a result, extreme (large and small) conditional quantiles of the endogenous variable are increasing in the exogenous variable. We develop a likelihood-ratio test based on estimates for the conditional quantiles of the endogenous variable, which is an asymptotic extension of Bartholomew's (1959a,b) "chi-bar squared" test. Our assumptions are weak; we remain agnostic about the cardinality, location and probabilities of the equilibrium set, and make no restrictions on the equilibrium-selection procedure.
