This paper develops methods of inference for nonparametric and semiparametric parameters defined by conditional moment inequalities and/or equalities. The parameters need not be identified. Confidence sets and tests are introduced. The correct uniform asymptotic size of these procedures is...

This paper presents a consistent GMM residuals-based test of functional form for time series models. By relating two moments we deliver a vector moment condition in which at least one element must be non-zero if the model is mis-specified. The test will never fail to detect mis-specification of...

Econometric methods based on the first-order conditions of intertemporal optimization models have gained increasing popularity in recent years. To a large extent, this development stems from the celebrated Lucas critique, which argued forcibly that traditional econometric models are not...
