The purpose of this study is to investigate the effect of local macroeconomic indicators and global risk factors on the participation index in the Turkish stock market from May 2011 to April 2021. Using the quantile regression approach, we detect the impact of local macroeconomic indicators and global risk factors across different market conditions: bull, bear, and normal. The empirical results demonstrate that, among local macroeconomic indicators, monetary policy-related indicators, Consumer Price Index (CPI)(Slope of Government Bond [SGB]), merely influence participation 30 index (KAT30) return in bearish market (bullish market); however, credit default swap negatively affects KAT30 return across all quantiles. When it comes to global risk factors, results show that KAT30 return is negatively affected by the implied volatility index across all quantiles except Q0.75 and Q0.95. This means that the implied volatility index impact on KAT30 return is stronger during the bearish market. Yet, Oil Volatility Index (OVX) and Morgan Stanley Country Index (MSCI) positively impact the index return across upper quantiles. göstergelerin

Soft power is a new concept in international relations and its history has been a question of interest in recent years. The term has been also widely used in the studies of Turkish foreign policy in the last two decades. This study aims to demonstrate that the use of soft power in Turkish foreign policy was not new and has a history of its own which dates back to the Ottoman Empire. The study will not present a historical study of its own that focuses on a certain event or phenomenon but bring together examples of how the Ottoman Empire has used means of soft power in its relationship with other states. By comparing these examples over time, it hopes to call attention to how Ottoman soft power has changed over time depending on the shifts in the international balance of power.
