Total Factor Productivity Convergence Amongst Italian Regions: Some Evidence from Panel Unit Root Tests
2009
Byrne J. P., Fazio G. and Piacentino D. Total factor productivity convergence among Italian regions: some evidence from panel unit root tests. Regional Studies. This paper employs panel unit root tests to investigate convergence in total factor productivity (TFP) among Italian regions. These tests provide an inference valid in the presence of heterogeneity and cross-sectional dependence, and when the cross-sectional dimension is smaller than the time dimension, allowing the investigation of convergence among different subsets of regions. The results add a further dimension to the conventional view on growth dynamics in the Italian peninsula depicting a lack of regional TFP convergence not o…
Unemployment Hysteresis in Transition Countries: Evidence using Stationarity Panel Tests with Breaks
2008
The authors test hysteresis versus the natural rate hypothesis in unemployment using panel data for transition countries covering the period 1991:1–2003:11.The advantages of the stationarity tests applied is that they exploit the cross-section variations of the series and, additionally, allow for a different number of endogenous breakpoints in the unemployment series. They do not impose independence on the panel members, so that the critical values are simulated based on their specific panel sizes and time periods. The findings stress the importance of accounting for exogenous shocks in the series and give support to the shifting natural-rate hypothesis of unemployment for all the countries…
