This paper surveys the growing literature on diagnostic testing of models based on unit record data. We argue that while many of these tests are produced in a Lagrange multiplier framework they are often more readily derived, and more easily applied, if approached from the conditional moment...

We perform maximum-likelihood estimation of a model of international asset pricing based on CAPM. We test the restrictions imposed by CAPM against a more general asset pricing model. The "betas" in our CAPM vary over time as the supplies of assets change and as the conditional covariances or...

We define a hierarchy of parametric and semiparametric specifications for censored regression models that is ordered according to the strength of the assumptions that are made. We review the estimation techniques and specification tests that are available at each level of the hierarchy. The...

This paper investigates firms' employment and output decisions and presents some empirical evidence concerning the rationality of firms' expectations. The dynamic model is based on the assumptions of convex adjustment costs and monopolistic competition in the product market. The results are...
