Dans Cet Article, Nous Evaluons L'effet de Deux Types de Lois du Travail Sur la Productivite et la Greve, a Savoir Celles Visant a Reduire L'activite de Greve et D'autres Qui Ne Cherche Pas a Reduire L'activite de Greve Mais Qui Peuve L'affecter Indirectement Par Leur Incidence Sur les Repports...

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 frame-work of...

This Paper Proposes Some New Tests for Detecting the Presence of a Unit Root in Quite General Time Series Modesl. Our Approach Is Nonparametric with Respect to Nuisance Parameters and Thereby Allows for a Very Wide Class of Weakly Dependent and Possibly Heterogeneously Distributed Data. the...

This paper studies the transition between exchange rate regimes using a Markov chain model with time-varying transition probabilities. The probabilities are parameterized as nonlinear functions of variables suggested by the currency crisis and optimal currency area literature. Results using...

Stock and Watson (1986) Tests the Hypothesis That Real Per Capita Gnp Has a Unit Root by Using a Test Statistic Due to Phillips (1985) Which Incorporates a Nonparametric Correction for the Serial Correlation Induced by System and Error Dynamics. the Version of This Test That Is Used by Stock and...
