    The impact of COVID-19 on Turkey’s tourism sector: fresh evidence from the fractional integration approach
    (Routledge, 2022) Yucel, Ali Gokhan; Koksal, Cihat; Acar, Sevil; Gil-Alana, Luis Alberiko
    The aim of this paper is to analyze whether the profound effects of COVID-19 on Turkey’s tourism sector will be permanent or transitory. Such an investigation deserves attention during the ongoing pandemic due to the importance of Turkey in the international tourism industry. To better understand and analyze the dynamics of tourism, we examine a long period of time spanning from January 1977 to March 2021 using a fractional integration approach. The findings provide clear-cut evidence that the shocks to the tourism sector display very low degrees of persistence in the pre-pandemic period whereas degrees of persistence in the post-pandemic period are very high. We also identify the changes in the persistence of tourism month by month. Overall, the impacts of COVID-19 on Turkey’s tourism will not be transitory. Therefore, the government should be actively involved in the recovery process of the tourism sector if Turkey wants to reach the number of tourist arrivals it once used to host. Also, the methodology employed in this study could be used as a benchmark to explore the impacts of the ongoing pandemic on other sectors

    The role of shadow economies in ecological footprint quality: empirical evidence from Turkey
    (SPRINGER HEIDELBERG, 2020) Koksal, Cihat; Isik, Mehtap; Katircioglu, Salih
    The purpose of this research study is to investigate the role of shadow economies in the levels of ecological footprint for the case of Turkey. Annual data set ranging from 1961 to 2014 was used with this respect. The results of this study verify the long-term and positively elastic impact of shadow economic activities on the level of ecological footprint in Turkey; that is, 1 % change in shadow economic activities results in a 1.008% change in ecological footprint in the same direction. This study, therefore, reaches a significant conclusion that in Turkey, shadow economies are long-term and essential drivers of environmental pollution.
