  Does ecological footprint in ECCAS and ECOWAS converge? Empirical evidence from a panel unit root test with sharp and smooth breaks

  Çelik, Orkun; Adali, Zafer; Bari, Bilgin

  The costs due to climate change have been increasing day by day. In addition to the risk of losing our planet’s natural assets due to the increasing destructiveness of climate-related natural disasters and extreme climate events, we are also faced with grave economic risks. For this reason, researchers have recently focused on environmental issues. Nevertheless, they generally have investigated developed countries and ignored developing and least developed countries such as African countries. The United Nations (2015) report highlights that African countries should be specially investigated. Hence, the paper analyzes whether the ecological footprint in the Economic Community of Central African States (ECCAS) and Economic Community of West African States (ECOWAS) converges for the period from 1961 to 2017. We employ Bahmani-Oskooee et al.’s (2014) panel unit root test with sharp and smooth breaks. The empirical findings demonstrate that the ecological footprint is stationary in ECCAS and ECOWAS. Stated in other words, the ecological footprint in these countries converges. Therefore, policymakers could implement similar policies to reduce the ecological footprint in these countries. This policy framework paves the way for an effective sustainable development.

  Testing the Short, Medium, and Long-Term Effects of Shocks on Ecological Balance

  Yilanci, Veli; Adali, Zafer; Çelik, Orkun; Bari, Bilgin

  Ecological balance is an indicator of environmental degradation, which is computed as the difference between biocapacity and ecological footprint. In this study, we examine whether the effect of shocks on the ecological balance is permanent or temporary in the EU-15 countries, considering the period from 1961 to 2018. The application of unit root tests, with and without a Fourier function, indicates that the effects of shocks are temporary in only four countries. To reveal the persistence of shocks at different frequencies, that is, the short-, medium-, and long-run, we decomposed the ecological balance series by using the Discrete Wavelet Transform method. The unit root test results show that the effects of shocks are temporary in all countries in the short-run. However, the results also show that the shocks are temporary in nine countries in the medium-run and ten countries in the long-run. Thus, the implemented policies to balance ecology are not effective in the short-run but are effective in only six countries in the medium-term and in only five countries in the long-term. These findings demonstrate the importance of considering different frequencies when testing the effectiveness of empirically implemented policies. Regarding policy implications, this study suggests focusing on medium- and long-term environmental policies rather than short-term ones.
