Yetkilendirilmis Yukumlu Statusu (YYS), temelleri gumruk-isletme isbirligine dayanacak sekilde Dunya Gumruk Orgutu (DGO) tarafindan hazirlanmis bir programdir. Programin temel amaci, gumruk idareleri tarafindan belirlenen gerekli kriteri yerine getirebilen guvenilir ve dusuk riskli firmalarin tespiti ve sertifikasyonudur. Tedarik zinciri acisindan, bu belgeye sahip olmak; uluslar arasi ticaret surecinde kalite ve guvenlik artisi ile zaman ve maliyet tasarrufu gibi faydalar saglamaktadir. Programin 2013’te Turkiye’de uygulamaya girmesinden itibaren 267 firma bu belgeyi almis ve katilimci firmalar programin baslarinda karsilastiklari guclukler ile gelinen noktada tecrube etmeye basladiklari faydalarini degerlendirebilecek konuma ulasmislardir. Buna bagli olarak bu calisma Turkiye’deki YYS programinin etkilerini nitel arastirma yontemi ile tedarik zinciri perspektifinden YYS sahibi firmalarin tecrube ettigi guclukleri ve faydalari goz onunde bulundurarak degerlendirmeyi amaclamaktadir....

One of the most important factors affecting international trade is exchange rate fluctuations. To date, studies that have analyzed the effect of exchange rates have shown that the effect can vary from sector to sector and from country to country. The fact that this relationship has not been extensively studied in the fisheries industry is the motivation for this study. In this regard, the aim of this study is to determine whether changes in the real exchange rates of countries affect their fisheries production levels. Accordingly, we used the causality test developed by Emirmahmutoglu and Kose (2011), which takes into account both cross-sectional dependencies and heterogeneity. The data set used in this study consisted of 27 annual observations from 38 countries from 1990-2016. The results revealed that changes in the real exchange rate affected fisheries production. This situation shows that changes in exchange rates may affect the international demand for fisheries and serve as a source of motivation for producers.

The aim of this study is to determine the causal relationship between the tonnage of containers handled at the Turkish ports and major exchange rates. Especially the recent extreme rise in exchange rates in the country increases the motivation of the study. There have been certain studies in the port literature and the results of which contradict one another. It is thought that this situation stems from the use of methods that generate constant coefficients based on the whole sample. In this respect, it is hoped that this study also makes an important contribution to the literature by its method. Time-varying causality method, which allows to determine the causal relationship in the course of time by dividing whole sample into sub-samples instead of examining the causal relationship based on whole sample, is used in the study. The dataset consists of 178 monthly observations and covers the dates between January 2004 and October 2018. According to the results of the analysis carried out in the study, in some periods of the sample, significant causal relations are determined from exchange rates to the volume of container handled at the Turkish ports. In particular, there is a significant causality to the container tonnage handled from the excessive exchange rate increase in recent periods. Due to the derived demand structure, the demand for the ports also varies with the volume of trade. Exchange rate is one of the most important factors of international trade, however dominance of the factors can change over time. It is seen that the conducted studies about the topic have contradictory results. It is thought that this situation stems from methodological constraints and the result of the time-varying causal relation obtained in this study provides a solution to all these contradictions.
