The human development indicator (HDI) is based on three indicators: standard of living, life expectancy, and education level. Although being widely known and commonly used, the accuracy of the HDI has been criticized in the literature due to the inadequacy of its indicators. The present study uses 11 indicators to classify countries and compares the results by country groups against similar HDI ranked country groups. Furthermore, using multinomial logistic regression analysis, the effects of the 11 indicators on the country categories of HDI are investigated. The findings show that although the main cluster characteristics are similar to HDI categories, some differences exist in the classification of countries. Health indicators have a striking effect on low HDI countries relative to high HDI countries. FDI inflows and CO2 emissions per capita are significant indicators for low and middle HDI relative to high HDI countries. However women's involvement in parliament and work are not distinctive or effective indicators.

Environment is one of the gripping topic with the importance of the protection of it for future generations. In recent years, greenhouse gas emissions are important threat for environment. Within greenhouse gas emissions, CO2 emissions takes big share. On the other hand, in the global World capital movements gain speed and foreign direct investment inflows gradually increase in Turkey. To this respect, we need to think about possible effects of these investments to environmental quality of country. In this sense, this paper examines the relationship between foreign direct investment inflows and CO2 emissions for Turkey. The study covers 1980-2011 period. The Bounds test developed by Pesaran et al. (2001) is applied to investigate the relationship between series for given period of time. According to bounds test results, there is no cointegration relationship between foreign direct investment inflows and CO2 series for Turkey. In other words, in the long term fdi inflows and CO2 emissions do not move together.
