Article Is there convergence in renewable energy deployment? Evidence from a new panel unit root test with smooth and sharp structural breaks(2023) Çorakçı, Ayşegül; Omay, TolgaThis study examines whether the contribution of renewable energy to the total primary energy supply converges in a panel of 24 OECD countries over the period 1960–2020. To this end, a new panel unit root test that allows for both sharp and smooth breaks is proposed to test for the stochastic convergence hypothesis. Although renewable energy convergence is not rejected when the newly proposed test is applied to the full panel of OECD countries, it found only moderate support within the members of the panel using a sequential panel selection methodology. In fact, in two high-income OECD countries, the contribution of renewable energy to the primary energy supply shows no sign of convergence: Poland and Iceland. Therefore, the renewable energy shares seem to be converging to a common steady state in only a group of OECD countries over the long run. This uneven pattern of convergence, in turn, suggests that the OECD countries are still far away from developing a common sustainable renewable energy target, calling for urgent international policy cooperation to encourage the divergent economies to seek out the menu of policies that ensure the worldwide success of renewable energy transformation.Article Citation - WoS: 9Citation - Scopus: 7The Effects of Federal Regulations on Corruption in Us States(Elsevier Science inc, 2020) Gunalp, Burak; Dincer, OguzhanUsing the newly constructed Federal Regulation and State Enterprise Index (FRASE Index) to measure the federal regulations and the existing Corruption Convictions Index (CCI), we investigate the effects of federal regulations on corruption in U.S. states. Controlling for several demographic and economic variables including the Fraser Institute's Economic Freedom Index (EFI), which measures the size and scope of government in U.S. states, we find a positive and statistically significant relationship between federal regulations and corruption. Our findings have important policy implications. A 1 standard deviation increase in FRASE Index causes CCI to increase by approximately 0.5 standard deviations. Standardized coefficient of EFI is also approximately equal to 0.5. In other words, it is possible to mitigate the effects of regulations at the federal level by reducing the size and the scope of the government at the state level.Article Citation - WoS: 12Citation - Scopus: 13Transportation-Communication Capital and Economic Growth: a Vecm Analysis for Turkey(Routledge Journals, Taylor & Francis Ltd, 2012) Eruygur, Aysegul; Kaynak, Muhtesem; Mert, MerterThis paper analyses the short- and long-term relationships between the transportation-communication capital and the output for Turkey. The study applies a Cobb-Douglas production function under the assumption of constant returns to scale and employs co-integration analysis by estimating a vector error correction model (VECM). As a result of the VECM estimation, one co-integrating relationship is detected. The results based on the impulse response function analysis imply that per labour transportation-communication capital appears both to have been a crucial input in the Turkish productive process and to have had a positive crowding in effect on the per labour non-residential total capital formation. Moreover, the results support the argument that the transportation-communication capital has a lagged impact on economic growth. The long-term accumulated elasticity of output to transportation-communication capital has been found to be 0.59. The long-term accumulated marginal product was also calculated. It implies that a 1 Turkish Lira increase in per labour transportation-communication capital results in a long-term rise of 1.45 Turkish Liras in per labour output. All these findings suggest that transportation-communication capital may be a powerful tool for policy-makers to promote long-term per labour real output growth in Turkey.
