This paper examines changes in the Greek wage distribution over 1995-2002 and the role of skill in these changes. The methodology adopted is the Machado-Mata counterfactual decomposition, which separates the part of wage changes that is due to job and workers' characteristics (composition...

Recent theoretical and empirical work has demonstrated a clear negative link between macroeconomic and political uncertainty and levels of private investment across countries. This result raises the question what institutions might help reduce this uncertainty, in particular by allowing host...

In this paper, I illustrate the additional information that can be prodivided in estimating the lower bound (Sutton 1991, 1998) by using quantile regression. Quantile regression allows us to invesigate the influence of outliers. Previous lower bound have been performed using the simplex method....

Collective bargaining in Germany takes place either at the industry level or at the firm level; collective bargaining coverage is much higher than union density; and not all employees in a covered firm are necessarily covered. This institutional setup suggests to distinguish explicitly union...

We develop non-nested tests in a general spatial, spatio-temporal or panel data context. The spatial aspect can be interpreted quite generally, in either a geographical sense, or employing notions of economic distance, or when parametric modelling arises in part from a common factor or other...

We provide a general class of tests for correlation in time series, spatial, spatiotemporal and cross-sectional data. We motivate our focus by reviewing how computational and theoretical difficulties of point estimation mount as one moves from regularly-spaced time series data, through forms of...

This paper uses a difference-in-difference estimator to test whether the introduction of patient choice and hospital competition in the English NHS in January 2006 has prompted hospitals to become more efficient. Efficiency was measured using hospitals’ average length of stay (LOS) for...

The convergence hypothesis has generated a huge empirical literature: this paper critically reviews some of the earlier key ndings, claries their implications, and relates them to more recent results. Particular atten- tion is devoted to interpreting convergence empirics. The main ndings are:...
