The Convergence Analysis of Co2 Emissions Intensity Performance of The Countries According To the Climate Change Performance Index
(Eskisehir Osmangazi Univ, Fac Education, 2016) Yazgan, Sekip; Mollavelioglu, M. Sukru; Ceylan, Resat
In this study, it is analysed whether the countries with good, moderate, poor and very poor performance according to the Climate Change Performance Index (Bruck, Marten and Bals, 2013) converge towards the average group in terms of emission intensity performance. The aim of the study is to examine whether the countries with same performances in climate change also display similar attitudes in terms of emission intensity performance. As the emission intensity performance index, ratio of the country's share in global emissions release to the share of the country's GDP in global GDP has been used. In the analysis, KSS and AESTAR units root tests based on nonlinear time series analysis techniques have been applied. According to the findings; there is convergence behaviour towards the average in terms of emissions intensity performance for each country group. However, it is noteworthy that, this convergence behaviour is more intense in group of countries with good performance and poor performance. Regarding the convergence behaviour between the groups, only the group average of the countries with moderate performance converges towards the group average of the countries with good performance according to the AESTAR test. However, convergence behaviour does not exist between the group averages according to the ADF and KSS tests. For this reason, in the convergence analysis of the emissions intensity performance, unit root tests based on nonlinear time series technique is more useful than the traditional ADF unit root test.
A Convergence Analysis on the Investment Development Path Approach
(Sosyoekonomi Soc, 2021) Yazgan, Sekip; Ceylan, Resat; Mollavelioglu, Sukru
This study, which examines whether the investment development path curves of the developed and developing countries show convergence behaviour in the 1970-2018 period, has two main objectives. The first is to analyse whether foreign direct investment eliminates the development differences between countries based on the investment development path approach. Using the nonlinear unit root tests developed recently, the second is to investigate whether the convergence behaviour of the investment development path curves is affected by macroeconomic shocks. According to the findings, these countries' investment development path curves exhibit a non-linear convergence behaviour, and therefore the convergence process is affected by macroeconomic shocks.
