The purpose of the present Evaluation Study is to discuss the methodological problems researchers are facing in gauging the impact of aid on economic growth. The discussion is nontechnical and aimed at an audience without much prior knowledge in the fields of macroeconomics and econometrics. The...

The purpose of the present evaluation study is to discuss the empirical studies that attempt to estimate the impact of foreign aid on economic growth. The study draws on a previous evaluation study (Dalgaard and Hansen, 2009), which introduces the general econometric methodology involved in...

We consider a monopolistic firm producing a good while polluting and using a fossil energy. This firm can adopt a clean technology by incurring an investment cost decreasing exponentially with the adoption date. This clean technology does not pollute and has a lower production cost because it...

We use the autoregressive distributed lag (ARDL) bounds testing approach for cointegration with structural breaks and the vector error correction model (VECM) Granger causality approach in order to investigate relationships between per capita CO2 emissions, GDP, renewable and non-renewable...

Based on the Environmental Kuznets Curve (EKC) hypothesis, this paper uses panel cointegration techniques to investigate the short and the long-run relationship between CO2 emissions, economic growth, renewable energy consumption and trade openness for a panel of 24 Sub-Saharan Africa countries...

We use panel cointegration techniques to examine the relationship between renewable energy consumption, trade and output in a sample of 11 African countries covering the period 1980-2008. The results from panel error correction model reveal that there is evidence of bidirectional causality...

This paper is an attempt to investigate the causal relationship between economic growth and combustible renewables and waste consumption for 12 countries of the Middle East and North Africa (MENA) region during the period of 1975-2008 using panel cointegration techniques and panel causality...
