Both policy makers and scholars frequently use monthly industrial production index series in their econometric predictions. In this paper, the stationarity properties of level, logarithm, seasonally adjusted level and seasonally adjusted logarithm of the Turkish industrial production index (TUIK) are investigated using both traditional unit root tests and unit root tests that have more power in small samples. Additionally, unit root tests that determine structural breaks endogenously are also employed. The traditional and relatively more recent tests seem to contradict each other Furthermore, there are structural breaks in the series. Therefore, model choices based on traditional unit root tests and policy implications derived from such models may not be correct. This study can help studies that employ the Turkish industrial production index in assessing the stationarity properties of the index.

The Relationship between the composite index and industrial stock indexes Hacıhasanoğlu, Erk; Soytaş, Uğur (2011-07-01) Makroekonomi ile hisse senedi piyasalarındaki ilişki yazında çok sayıda çalışma tarafından ele alınmıştır. Yazındaki çalışmalarda kullanılan değişik makroekonomik değişkenler arasında yüksek korelasyon olduğundan, istatistiksel modellerde çoklukolineerlik problemi ortaya çıkabilmektedir. Ayrıca yazında çoğunlukla hisse senedi piyasalarına genel olarak bakılmış ve makroekonomik dinamiklerin sektörel endekslere etkileri ayrıntılı olarak incelenmemiştir. Bu çalışmada TCMB’nin yayınladığı bileşik öncü göst...
The Effects of bank specific, industry specific and macroeconomic factors on bank profitability in OECD countries between 2000-2009 Maltaş, Zeynep; Ayaydın Hacıömeroğlu, Hande; Department of Business Administration (2013) This thesis analyzes the bank-specific, industry-specific and macroeconomic determinants of bank profitability (ROA) in 31 OECD Countries between 2000 and 2009 using a panel data. Each country‟s banking sector is treated as a single representative bank. Fixed effects model is used in the study. Deposits, capitalization, non-interest income, GDP growth are found to have a positive impact on bank profitability while non-performing loans, operating expenses and financial sector development have negative effect...
The effects of domestic and international news and volatility on integration of Chinese stock markets with international stock markets ÖZTEK, MEHMET FATİH; Öcal, Nadir (2016-03-01) This paper provides a comprehensive and up-to-date analysis of time-varying return co-movements between Chinese stock markets and stock markets in the USA, UK, France and Japan by employing smooth transition conditional correlation (STCC-GARCH) and double smooth transition conditional correlation (DSTCC-GARCH) models with specific emphasis on the role of domestic and international news and volatility. Unlike earlier literature, we reveal that there are noticeable rising trends in conditional correlations am...
The characteristics of financial innovation in developing countries : the case of Turkey Kılıçaslan, Seda; Cömert, Hasan; Department of Science and Technology Policy Studies (2019) Financial innovations are one of the important factors affecting the development of financial markets and have attracted more attention in the literature especially after the 1980s. In the existing literature, only a few studies investigate financial innovation processes in developing countries. The main purpose of this study is to investigate the factors influencing the emergence and development processes of financial innovations in Turkey. Thus, it is aimed to fill the gap in the development process of fi...
The importance of occupations in the Turkish labor market: job and wage polarization Akçomak, İbrahim Semih (2013-12-01) Recent literature has identified three trends in the labor markets of the industrialized countries: (i) employment share of services sector has increased, (ii) employment share in low and high skilled occupations has increased (job polarization), (iii) and similarly wages in the low and high skilled occupations have increased relative to middling jobs (wage polarization). In this paper, we investigate the existence of such findings in the Turkish labor market for the 2004-2010 period using Labor Force Surve...
