Mean Reversion in Stock Prices: New Evidence from Panel Unit Root Tests for Seventeen European Countries

There is a large and growing literature that investigates evidence for mean reversion in stock prices. Empirically, there is no consensus as to whether stock prices are mean reverting or random walk processes; at best, the results are mixed. In this paper, we provide further evidence on the mean reversion hypothesis for seventeen European countries using the Levin and Lin (1992), seemingly unre...

Are Mortality Rates Random Walk? Panel Unit- root Tests with the Evidences from Micro Data*

This study investigates the relationship between economic conditions and health. Previous studies have estimated that they have a significantly negative correlation. However, there is a concern that mortality rates are non-stationary series, with which a chance of spurious correlation exhibits. By taking first difference on regressors and conducting unit-root tests for panel data, it shows some...

Determinants of Healthcare Expenditure in Economic Cooperation Organization (ECO) Countries: Evidence from Panel Cointegration Tests

Background Over the last decade there has been an increase in healthcare expenditures while at the same time the inequity in distribution of resources has grown. These two issues have urged the researchers to review the determinants of healthcare expenditures. In this study, we surveyed the determinants of health expenditures in Economic Cooperation Organization (ECO) countries.   Methods We us...
