OLS estimation of an impulse-indicator coefficient is inconsistent, but its variance can be consistently estimated. Although the ratio of the inconsistent estimator to its standard error has a t-distribution, that test is inconsistent: one solution is to form an index of indicators. We provide...

In this paper, we build a model for the yield curve in Germany, from 1975 to 2001, and use it to test the Lucas Critique. We provide a first application of the new general-to-specific automatic model selection algorithm embodied in PcGets to term structure odeling, and use new super exogeneity...

This study explores a new data set that contains information both on inputs and outputs for a sample of Portuguese secondary schools. An FDH reference technology is used to determine radial technical efficiency scores and slacks. Although it is known that there is no reason to assume convexity...
