Traditional methods of testing the Capital Asset Pricing Model (CAPM) do so at the mean of the conditional distribution. Instead, we test whether the conditional CAPM holds at other points of the distribution by utilizing the technique of quantile regression (Koenker and Bassett 1978, Buchinsky...

In the current paper, a one-sided version of a small sample correction to AIC is derived. This criterion will be based upon a two-sided model selection cretirion called AICs developed by Sugiura (1978) and studied in detail by Hurvich and Tsai (1989, 1991).

In this paper, we investigate whether similar improvements are observed when we have a non-sample information regarding the nuisance parameters in the testing problem. It is shown under several realistic regularity conditions, that tests based on inequality constrained estimates of nuisance...

Numerous papers have searched for empirical linkages between long run economic growth and a myriad of economic, socio-political and environmental factors. Most of these studies use ordinary least-squares regression or panel regression analysis on a sample of countries and therefore consider the...

In a recent paper, Hughes (1999) showed that the power of tests of linear regression parameters could be improved by utilizing one-sided information regarding the nuisance parameters in the testing problem. In this paper, we extend this principle to the problem of diagnosing departures from the...
