Using several different unit root/stationarity tests on single time series Konya (2000) found the logarithm of real GDP of most OECD countries behaving as a random walk during the last four decades. This outcome, however, might be due to the generally low power of these tests. The aim of this...

This paper is concerned with the possible bivariate Granger causality between immigration, measured as the proportion of net permanent and long-term movement to resident population, and long-term unemployment, measured as the proportion of long-term unemployed to total unemployed, in Australia...

Following Konya (2000a, 2000b), this paper is the third in a series analyzing unemployment in Australia in the period of 1960 to 1997 with special regard to the unit-root versus stationarity hypotheses. It provides new evidence by allowing for the possibility of two endogenous breaks in the...

The aim of this paper is to analyze the rate and level of Australian unemployment, and also their logarithms, in the period of 1960 to 1997, with special regard to the unit-root versus stationarity hypotheses. Theoretically, the level of unemployment, the rate of unemployment and the logarithm...

This paper compares the basic properties of stationary autoregressive processes and random walks with special regard to their implications to unit root testing. In particular, it aims to answer three basic but important questions. Firstly: 'What do a constant term (drift) and a linear time trend...

This study seeks to find out whether there existed an empirically discernable and robust tendency in the world for countries to converge in terms of human development over the last three decades. Human development is measured by the Human Development Index trend and convergence across countries...

This article is a supplement to Kónya (2004) which investigates the possibility of the export-led growth and growth-driven export hypotheses by testing for Granger causality between the logarithms of real exports and real GDP in twenty-five OECD countries. In Kónya (2004) two complementary...

The aim of this paper is to study the potentially simultaneous relationship between income inequality and growth volatility for seventy countries between 1960 and 2002. Two types of analysis are performed; a cross-sectional analysis based on country averages of all available annual observations,...

The purpose of this study is to investigate empirically the presence of an equilibrium relationship between the logarithms of Indian exports and imports between 1949/50 and 2004/2005, using the unit-root, cointegration approach. To ascertain robustness, exports and imports measured in current...
