A reappraisal of the evidence on PPP : a systematic investigation into MA roots in panel unit root tests and their implications
Fischer, Christoph (contributor); Porath, Daniel (contributor) - 2006
Panel unit root tests of real exchange rates as opposed to univariate tests usually reject non-stationarity. These tests, however, could be biased if the real exchange rate contained MA roots. Indeed, two independent arguments claim that the real exchange rate, being a sum of a stationary and a...

In this paper we propose exact likelihood-based mean-variance efficiency tests of the market portfolio in the context of Capital Asset Pricing Model (CAPM), allowing for a wide class of error distributions which include normality as a special case. These tests are developed in the framework of...

The stable long-run CAPM and the cross-section of expected returns
Kurz-Kim, Jeong-Ryeol - 2002
The capital-asset-pricing model (CAPM) is one of the most popular methods of financial market analysis. But, evidence of the poor empirical performance of the CAPM has accumulated in the literature. For example, based on their empirical results regarding the relation between market Beta and...
