Throughout the post-war era until 1995 labour productivity grew faster in Europe than in the United States. Since 1995, productivity growth in the EU-15 has slowed while that in the United States has accelerated. But Europe’s productivity growth slowdown was largely offset by faster growth in...

This paper provides three perspectives on long-run growth rates of labor productivity (LP) and of multi-factor productivity (MFP) for the U. S. economy. It extracts statistical growth trends for labor productivity from quarterly data for the total economy going back to 1952, provides new...

This paper shows how misleading is the facile contrast of Europe following a path of high productivity growth, high unemployment, and relatively greater income equality, with the opposite path being pursued by the United States. While structural shocks may initially create a positive trade-off...

This paper derives the asymptotic distribution for a number of rank-based and classical residual specification tests in AR-GARCH type models. We consider tests for the null hypotheses of no linear and quadratic serial residual autocorrelation, residual symmetry, and no structural breaks. For...

A unifying framework for inference is developed in predictive regressions where the predictor has unknown integration properties and may be stationary or nonstationary. Two easily implemented nonparametric F-tests are proposed. The test statistics are related to those of Kasparis and Phillips...
