This study aims to investigate the effects of health expenditure on economic growth in Turkey. For this purpose, time series data of Turkey over the period 1975–2018 were evaluated. Moreover, household consumption, life expectancy at birth, trade, and foreign direct investments were added as control variables. Cointegration analysis was performed to test whether all variables are cointegrated in the long term. Causality test was successfully employed to investigate the relationship between health expenditure and economic growth in the short term. The achieved results exhibited that Johansen Cointegration test results suggest the existence of cointegration among all variables in the long term. In addition, the Granger causality test results indicate unidirectional causality from health expenditure to economic growth in the short term. Existence of a long-term relationship among related variables and a short-term relationship between health expenditure and economic growth displays the importance of investments on health care services in Turkey. Therefore, investments in the health sector should be encouraged and the share allocated by the government for health expenditures from the budget should be increased in Turkey.

In addition to the fundamental macroeconomic indicators such as inflation and interest rate which are very important for foreign investors, the Credit Default Swap (CDS), that shows the credit risk level of the country, is an important research topic. Therefore, in this study, it is aimed to examine the effects of Turkey CDS and selected macroeconomic variables on the Istanbul Stock Exchange (ISE) 30 index (XU30). For this purpose, Granger Causality Relations, Impulse-Response Charts and Variance decomposition were made under the VAR model for 2010: 06 and 2020: 02 monthly periods. According to the results of the study, it was concluded that there was no Granger Causality relationship from variables to XU30 and XU30 stock returns toward selected macroeconomic indices either. However, it is found that shocks in CDS for two and a half months were responded negatively by XU30 returns at the significant beginning. Also, the positive and significant impact of the interest rate is worth to consider.

İslami hisse senedi endeksleri, İslami kurallara uygun olarak belirlenen alanlarda faaliyet gösteren şirketler baz alınarak oluşturulan endekslerdir. İslami finansal araçlara yatırım yapan yatırımların temel amacı, geleneksel finansal araçlara yatırım yapan yatırımcılara benzer şekilde minimum risk ile maksimum getiriyi sağlamaktır. Bu amaçla yatırımcılar karar süreçlerinde varlıklara ve piyasalara ilişkin analizler yapmaktadır. Bu analizlerden biri de varlıklar arasındaki oynaklık ilişkilerinin yapısının belirlenmesidir. Oynaklık ilişkileri sabit veya dinamik yapıda olabilmektedir. Bu durum ise yatırım stratejilerinin belirlenmesinde dikkate alınması gereken bir faktördür. Oynaklık ilişkilerinin yapısının belirlenmesinde kullanılan testlerden biri Engle ve Sheppard (2001) tarafından geliştirilen dinamik korelasyon model testidir. Bu bağlamda çalışmada 15.
