It’s possible to express that energy prices in 2021 were much higher, compared to the crisis of 2020’s Covid-19 breakout’s historical descent in the first few months. There are a few factors to this rally. The epidemic caused structural fractions on a global scale. But in general, there is no doubt that crisis factors, which mainly concern Europe, are not limited (with) recovery process in the economy. With this notion, the main structure of this work’s subject aims to analyze the lead-up to the energy crisis that became apparent in 2021. Also, in the work, the energy crisis that’s been occurring will be analyzed thoroughly, with the help of its dynamics and causes.

Bu yaklaşım önceleri finansal sermaye ihtiyacı duyan az gelişmiş veya gelişmekte olan ekonomiler için bir can suyu niteliği taşırken, daha sonraları sermaye giriş çıkışlarındaki ani dalgalanmalar ülkelerin makroekonomik değişkenleri üzerinde olumsuz sonuçlara sebep olmuştur. Bu alanda daha önceki yapılan çalışmalara bakıldığında anlık sermaye hareketliliğinin ülkelerin reel döviz kurlarında, faiz oranları ve sermaye piyasaları üzerinde yüksek bir volatilite oluşturduğu, sonuçta buna bağlı olarak piyasaların finansal olarak daha kırılgan ve dışa bağımlı hale gelmesine neden olduğu görülmüştür. Bu nedenle ülkeler ortaya çıkan bu olumsuz durumu bertaraf etmek için sermaye kontrolü kuralları altında bir dizi düzenleme ve denetleme mekanizması geliştirmişlerdir. Bunlar içerisinde en yaygın yöntem Tobin vergisi uygulaması olup, birçok ülke tarafından farklı zamanlarda kullanılmıştır. Bu çalışmada ise 1992 yılından günümüze kadar uygulanmış sermaye kontrolleri incelenmiştir. Genel olarak sonuçlara bakıldığında farklı ülkelerde uygulanmış sermaye kontrolleri kısmen başarı sağlamış olsa da Malezya ve Şili dışında birçok ülkede başarısızlıkla sonuçlanmıştır. Birçok çalışmanın sonucunda ise; uygulamaların her ülkenin kendi ekonomik, finansal ve coğrafi dinamikleri dikkate alınarak yapıldığında başarıya ulaşmaya daha yakın olunacağı belirtilmiştir.

Accordingly, the increase and decrease in a country's trade openness directly and indirectly affects macroeconomic indicators. In short, it is important to know the expected relationship between trade openness and inflation for a country's economy. Investigating the relationship between trade openness and inflation is important in keeping inflation under control, along with foreign trade policy practices. On the other hand, the theoretical basis of the association between trade openness and inflation is known with the Romer (1993) Hypothesis. According to the Romer Hypothesis, it is argued that an increase in trade openness will negatively affect inflation. However, although there are findings supporting this theory for the studies done so far, there are empirical studies expressing the opposite. This study has investigated this relationship in MIKTA countries. Kónya (2006) panel causality test was used in the study using annual data between 1960 and 2020. In result of the paper, it is found that there is no causal linkage between trade openness and inflation in countries. These results do not coincide with the Romer (1993) Hypothesis.

Methodology-It was preferred for unit root tests of series the Zivot-Andrews Unit Root Test, which takes into account structural breaks. Depending on the stagnation of the variables at different levels, the Toda-Yamamoto (1995) causality test was applied by using weekly data in period 19.02.2017 and 07.02.2021. Findings-One-way causality was found on the indices of cryptocurrency price uncertainty and cryptocurrency policy uncertainty from bitcoin energy consumption. In addition, it is understood from the Chi-Square Test Statistic (13.16980) coefficient that the change in bitcoin energy consumption is more dominant on the crypto money policy uncertainty. It was reached that changes in bitcoin energy consumption have an effect on both price and crypto money policies in all crypto markets. Conclusion-In line with these results, it is concluded that the uncertainties in the crypto markets are under the influence of many external political factors. This study investigated the effect of price and political uncertainty on bitcoin energy consumption in the entire cryptocurrency market, but it was concluded that bitcoin energy consumption is not only linked to crypto markets, but also under the influence of government interventions, bans, ill-recognition, and developments and movements in other financial markets.

The data obtained from Germany, Iceland, Italy, Japan, Mexico, New Zealand, Portugal, Turkey, and the United States of America, which consume wind and geothermal energy, were utilized in the research study. To this end, after determining the cointegration relationship between the variables, the long-term elasticity coefficients were estimated by employing the FMOLS (2000) and DOLS (2001) models. As a result of the analysis, it was determined that geothermal energy consumption had a positive impact on financial development. Nonetheless, wind energy had no impact on financial development, whereas it had a negative impact on economic growth. According to the Dumitrescu–Hurlin causality test results, it was determined that a unilateral causality existed from wind and geothermal energy consumption to economic grow...

From this basic view, the relationship between the economic size of public sector and macroeconomic stability was examined in the study, in which Turkeyˈs data for the period 1980-2019 was used. According to the causality test results of Toda and Yamamoto (1995), it was concluded that there is a causal relationship from public expenditures to economic growth and inflation, but there is no causality relationship to unemployment. These results provide important evidence that changes in the size of the public sector are the cause of changes in economic growth and inflation.

The concept of metaverse refers to an alternative virtual universe in which individuals are represented by their avatars (virtual representation), they can create applications, socialize, buy and sell goods and services, and share. In addition, there are meta coins, i.e. local crypto coins, used in the metaverse. In this study, the concepts of metaverse and meta coin, which have become popular recently, are explained, and the existence of price bubbles in MANA, the meta coin of the Decentraland digital reality platform, which has the largest market value among meta coins, is investigated. Methodology-The existence of price bubbles is investigated by the newly developed GSADF multiple bubble test. Findings-According to the result of the analysis carried out with the GSADF test, the existence of price bubbles in MANA prices in different periods has been determined. Especially the bubbles that have formed in the recent period have been realized as a longer term. This situation shows the impression that significant speculative movements have occurred in the MANA token recently. Conclusion-According to the findings, MANA prices are open to speculation. It is important for those investing or considering investing in MANA and other meta coins to consider the existence of bubbles in the respective token prices.

In this context, the consumer confidence index and the geopolitical risk index have become increasingly popular in both econometric analyses and academic discussions. In this study, the effects of consumer confidence and geopolitical risk indices on food imports and exports in Turkey for the period between January 2013 and January 2021 were analyzed through symmetric and asymmetric causality analyses. The consistent results of the Toda Yamamoto causality and Hatemi-j asymmetric causality tests indicated that a decrease in the consumer confidence index in Turkey leads to a decrease in exports of processed food goods and an increase in geopolitical risk leads to an increase in imports of unprocessed food goods.

Bu çalışmada ise bu durumun iktisat literatüründe bir karşılığı olan Fisher Etkisi göz önünde bulundurularak incelenmiştir. Bu doğrultuda Ocak 2005-Ekim 2020 dönemleri arası aylık enflasyon ve faiz verileri kullanılarak Hatemi-J (2012) asimetrik nedensellik testi çalıştırılmıştır. Çalışmanın sonucunda ise genel itibari ile enflasyon oranları ile faiz oranları arasında nedensellik ilişkisinin olduğu yönünde bulgulara erişilmiştir. Değişkenlerin pozitif ve negatif şoklarına ayrılarak yapılan analizlerde ise enflasyondaki artış ile faizlerde ki artış arasında iki yönlü simetrik bir nedensellik ilişkisi tespit edilmiştir. Bununla birlikte, faizlerdeki artış enflasyonu hem simetrik hem de asimetrik etkilediği görülmüştür. Çalışmadan elde edilen bulgulara bakıldığında 2005-2020 yılları için Türkiye'de Fisher Hipotezi'nin geçerli olduğu sonucuna ulaşılmıştır.

The consistent results of the Toda Yamamoto causality and Hatemi-j asymmetric causality tests indicated that a decrease in the consumer confidence index in Turkey leads to a decrease in exports of processed food goods and an increase in geopolitical risk leads to an increase in imports of unprocessed food goods.

Bu çalışmada ise bu durumun iktisat literatüründe bir karşılığı olan Fisher Etkisi göz önünde bulundurularak incelenmiştir. Bu doğrultuda Ocak 2005-Ekim 2020 dönemleri arası aylık enflasyon ve faiz verileri kullanılarak Hatemi-J (2012) asimetrik nedensellik testi çalıştırılmıştır. Çalışmanın sonucunda ise genel itibari ile enflasyon oranları ile faiz oranları arasında nedensellik ilişkisinin olduğu yönünde bulgulara erişilmiştir. Değişkenlerin pozitif ve negatif şoklarına ayrılarak yapılan analizlerde ise enflasyondaki artış ile faizlerde ki artış arasında iki yönlü simetrik bir nedensellik ilişkisi tespit edilmiştir. Bununla birlikte, faizlerdeki artış enflasyonu hem simetrik hem de asimetrik etkilediği görülmüştür. Çalışmadan elde edilen bulgulara bakıldığında 2005-2020 yılları için Türkiye'de Fisher Hipotezi'nin geçerli olduğu sonucuna ulaşılmıştır.
