The bounds and Bayer-Hanck tests for cointegration indicates that the analyzed variables are cointegrated. ARDL test result revealed that there is a one-way and statistically significant relationship moving from coal consumption per capita, financial development and income per capita to carbon emission per capita in the long-run. The negative impact of financial development on carbon emissions shows that as financial development in Mexico increases, environmental pollution decreases. This inverted U-shaped relationship, which is statistically significant between income per capita and carbon emissions per capita, supports the Environmental Kuznets Curve hypothesis. Applying conservative policies may cause a decrease in economic growth because the increase in coal consumption increases carbon emissions. Therefore, the efficient use of energy resources should be a primary goal of policy makers.

The results of autoregressive distributed lag (ARDL) approach, bounds testing and error correction model show that there is a positive one-way and statistically significant causality moving from electricity consumption to economic growth in the short-and long-run. The empirical results show that electricity consumption and economic growth are not neutral with respect to each other, and therefore energy conservation policies should not be applied. The growth hypothesis is valid for five IEA countries. Electricity consumption encouraging policies support to these countries economic growth.

VAR nedensellik analizlerine göre, D ve Y arasında çift yönlü; Y'den D'ye pozitif, D'den Y'ye negatif bir nedensellik ilişkisi vardır. Varyans ayrıştırma analizinin 15 yıllık ortalaması, Y'deki değişmede %13 ile %30 oranlık payın D'den ve %1 ile %6'lık payın I'dan kaynaklandığı; D'de meydana gelen değişmede Y'nin payının %32 ile %34 ve I'da meydana gelen değişmede Y'nin payının %21 ile %23 olduğu belirlenmiştir. Abstract This study employed the TY/U-VAR causality methods to analyze the relationship between direct (D) and indirect tax revenues (I) and gross domestic product (Y) in Turkey by using annual data from 1980 to 2013. According to the VAR causality results; there is a two-way causality relationship between D and Y; positive causality from Y to D and negative causality from D to Y. The variance decomposition analyses on 15-year average also show that D (I) explains 13% and 30% (1% and %6) of the

In this study, energy consumption and economic growth relationships are estimated by ARDL method for the period 1960-2014 both in the long and short term. The results indicate that there is a one way positive and statistically significant causality is going from total and per capita primary energy consumption to economic growth in the long and short run. Policy makers should support the energy consumption in order to stimulate economic growth.

using Sims, modified Sims, Toda-Yamamoto causality, variance decomposition analyses and impulse-response functions from 1950 to 2012 period in Turkey. Alternative causality tests show that there is a positive uni-directional causality running from the GDP to the number of
graduated university students and from the graduated regular and vocational high schools students to the GDP.

Econometric findings imply that there is one-way (positive) causality from the economic growth to the number of students completing university and one-way (positive) causality from the number of students completing vocational high school and the number of students completing high school to the economic growth.
