The asymmetric effects of foreign direct investment on clean energy consumption in BRICS countries: A recently introduced hidden cointegration test Yılancı, Veli; Onder Ozgur; Muhammed Sehid Gorus This study investigates the effects of foreign direct investment and the trade openness on clean energy consumption for BRICS countries-Brazil, Russia, India, China, and South Africa-during the period 198 -2017. For that purpose, the study employs Fourier ADL (Autoregressive Distributed Lag) and hidden Fourier ADL cointegration tests and Fourier Toda-Yamamoto approach to Granger causality considering both raw data and the asymmetric components of the series. Empirical results reveal that these variables are cointegrated in Russia, China, and South Africa regarding hidden Fourier ADL cointegration test while they are cointegrated only in South Africa considering the Fourier ADL test. It is found that trade positively affects clean energy use in South Africa. In the context of negative components, Foreign direct investment has a positive impact on clean energy use in Russia, while its effect is insignificant in China and South Africa. Moreover, trade openness influences clean energy consumption negatively in Russia, China, and South Africa. According to the Fourier Toda-Yamamoto and asymmetric Fourier Toda-Yamamoto causality tests results (regarding negative components), there is unidirectional causality from foreign direct investment inflows to clean energy consumption in China. Findings of this study may provide beneficial information to the policymakers to design proper environmental policies such as the imposition of the carbon tax and subsidy on cleaner energy consumption.

The Ottoman dissolution and the Istanbul bourse between war and peace: a foreign exchange market perspective on the Great War Hanedar, Avni Önder; Hatice Gaye Gencer; Sercan Demiralay; Ismail Altay The participation of the Ottoman Empire in the First World War caused economic disruptions, huge budget deficits, surmounted inflation rates and excessive depreciation of Lira, the Ottoman currency. Based on the value of Lira against the currencies of Switzerland, Netherlands, Sweden that were not in the war, we focus on the effects of news about the war on the foreign exchange rates at the Istanbul bourse from 1918 to 1919. Our results signify some dates, which match the announcements of the armistices and peace meetings, heralding continuous depreciation of Lira. Thus, the findings support the presence of an expectation on the dissolution of the Ottoman Empire with the peace, marked by the escalation of the loss in trust for the Lira and the power of the state in foreign exchange interventions.

The effect of economic growth on obesity for the most obese countries: new evidence from the obesity Kuznets curve Aydın, Mücahit; Aydın, Mücahit In this study, the relationship between obesity and economic growth has been examined within the framework of the obesity Kuznets curve (OKC) for the top 20 obese countries from 1991 to 2016 using bounds test based on ARDL. Multiple models were used in the study, including unemployment variable instead of single model. The bounds test results show that there is a cointegration between the variables in all countries except Bahamas, Fiji, Mexico, New Zealand, Tunisia, and UK. The long-run coefficients show that OKC hypothesis is valid for Oman, Saudi Arabia, Turkey and the United Arab Emirates. The main finding of this study is that countries should improve the welfare of individuals to encourage healthy lifestyles and reduce obesity risks.
