This paper analyses, within the new growth theory framework and using panel cointegration techniques, the effect of agricultural international technological spillovers on total factor productivity growth for a sample of 47 countries during the period 1970-1992. The analysis shows that total...

<font face="CMR9" size="1"><font face="CMR9" size="1">In this paper we propose new panel tests to detect changes in persistence. The test statisticsare used to test the null hypothesis of stationarity against the alternative of a change inpersistence from I(0) to I(1), from I(1) to I(0), and in an unknown direction. The limitingdistributions of the...</font></font>

This paper enlarges on Karlsoon and Löthgreen’s (2000) results on panel unit root tests to panel cointegration tests. We show that for homogeneous panel, Kao’s (1999) tests have higher (lower) power than Pedroni’s (1999) tests when a small-T (high-T) number of observations are included in...

In the paper we extend Gregory and Hansen’s (1996)ADF, Za, Zt cointegration tests to panel data, using the method proposed in Maddala and Wu (1999). We test the null hypothesis of no cointegration for all the units in the panel against the alternative hypothesis of cointegration, while...

We use two methodologies, the least square dummy variables approach and the dynamic factor models, to decompose the labor productivity growth rate for a large sample of countries into common, i.e. global, and idiosyncratic, i.e. country, components. We find that country specific effects are much...

This paper analyzes the effect of changing sampling frequencies on the empirical power of "first generation" as well as "second generation" panel unit root tests.

This paper deals with the finite-sample performance of a set of unit-root tests for cross-correlated panels. Most of the available macroeconomic time series cover short time periods. The lack of information, in terms of time observations, implies that univariate tests are not powerful enough to...
