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.

This paper focuses on the effects of global factors on the saving–investment relationship. We prove that, if investments and savings are affected by idiosyncratic and global components, they must be cointegrated to obtain reliable estimates of the saving-retention coefficient. When global...

In this paper we compare the changes in farm incomes in EU regions and US States between1989 and 2002. The aim of this comparative analysis is highlight the patterns of convergence or divergence and how they differ over time. We use two recent analytical instruments: non-stationary panel...

We review the constant discount rate present value model of farmland prices using non-stationary panel data analysis. We use panel unit root and cointegration analysis to test if the present value model holds for a sample of 31 U.S. States covering the period 1960-2000. Preliminary results...

Agriculture productivity varies dramatically in different regions of the world. Using recent theories of economic growth and recently provided data sets, this study finds some empirical regularities between agricultural labour productivity growth, investment and education, as well as...
