This study explores the empirical validity of long run Real Interest Parity (RIP) for a set of Asian countries for the period of January 1984 and August 2016 by taking Japan as a base country. We apply unit root test of Christopoulos and Leon-Ledesma (2010) which enables us to measure infrequent smooth temporary breaks and nonlinear mean reversion in the real interest rate differential (rid) series simultaneously. We model the smooth breaks by Fourier function while nonlinearity in rids series are model by modified versions of the most recently developed exponential smooth transition autoregressive (ESTAR) models of Kapetanios et al. (2003) and Kılıç (2011). The results provide strong evidence in favor of RIP for Asian countries when smooth breaks are taken into consideration and nonlinearity in the rids series are correctly specified. Our findings also reveal that for most of the countries Fourier functions have one frequency which is associated with 1997 Asian Crisis.

Interactions between macroeconomic fundamentals and term structure of interest rates be stronger according to the way of changes in structure of worldwide economy. Combined macro-finance analysis determines the joint dynamics of term structure of interest rates and macroeconomic fundamentals. This thesis provides analysis of two existing macro-finance models and an original one. Parameter estimations for these three macro-finance term structure models are done for monthly Turkish data by use of an efficient...
Smooth breaks and nonlinear mean reversion in real interest parity: evidence from East Asian countries
Gülcü, Abdullah; Yıldırım Kasap, Dilem (2018-11-03)
This study aims to explore the empirical validity of the real interest rate parity (RIP) hypothesis for East Asian countries using Japan as the base country. To this end, we employ the recently proposed unit root tests of Christopoulos and Leon-Ledesma (2010) that account for both multiple smooth structural breaks of unknown form and nonlinear mean reversion in the series. Our empirical results uncover overwhelming evidences in favor of the RIP hypothesis for the whole countries in our sample. More spe...

Nonlinearity in the real interest parity hypothesis
Kadakal, Zeynep Şeyma; Yıldırım Kasap, Dilem; Department of Economics (2013)
This study examines Real Interest Parity (RIP) hypothesis for some old and present members of European Free Trade Area (EFTA). The analysis entails the application of nonlinear unit root tests proposed by Kapetanios, Shin and Snell (2003) and Kılıç (2011) for January 1967 and August 2012 period, which coincides with some stages of Balassa’s (1961) economic integration classification. The results show that nonlinearity in real interest rate differentials is significant for most cases and more supportive evid...
Macroeconomic announcements and intraday stock market volatility
Yılmaz, Berna Nisa; Danışoğlu, Seza; Department of Financial Mathematics (2017)
This study examines the effects of interest and inflation rate announcements on stock market volatility by using a standard event study methodology. The BIST-30 Index volatility is modelled and forecasted by the multiplicative component GARCH model. This is one of the first studies where the announcement effects are analyzed on the basis of volatility forecasts produced by the multiplicative component GARCH. The announcement effects are observed clearly with the advantage of using high-frequency data. While...
