This paper uses a sample of 36 countries for the time period 1990-2011 in order to examine the relationship between countries’ electricity consumption from renewable sources and Gross Domestic Product (GDP) levels. Several nonparametric techniques are applied to investigate the effect of...

This paper explores the dynamic relations between the Romanian exports and imports using monthly data from January 2005 to March 2009. We test the cointegration and causality between the two variables. The results of Engle-Granger, Johansen and cointegration tests are ambiguous while the...

Using time series data, this paper investigates China’s carbon emissions during 1960-2006, with particular focus on the direct role of growth and in connection to trade and the value added by various sectors like agriculture, industry and services. Our empirical results indicate the presence...

By applying conditional and unconditional data envelopment analysis (DEA) models along side with statistical inference using bootstrap techniques; this paper investigates the link between China’s carbon dioxide emissions (CO2) environmental efficiency and its economic growth (measured in GNI...

This paper explores the relationship between CAC 40 Index and other three indexes from Central and East European countries: PX Index, BUX Index and BET-C Index before and during the global crisis. In our investigation we employ daily values of the four indexes from two periods of time: a...

This paper explores the impact of the foreign direct investment on the Romanian exports. We employ cointegration techniques and a Vector Error Correction Model to study the relations between the two variables. We find a significant influence of the foreign direct investment on the exports....

This paper explores the dynamic relation between the exports and the gross domestic product from Romania. We employ the Johansen cointegration procedure and the Granger causality test to identify the interactions between the two variables. We find no cointegration but a unidirectional causality...
