We follow novel procedure of [4] to assess presence of unspanned stochastic volatility (USV) phenomenon in the Turkish lira interest rate swap (IRS) market. The estimations reveal that IRS yield curve dynamics fail to span volatility in IRS market and thus volatility risk cannot be hedged using only IRS instruments. The major implication of USV is then used to investigate the systemic volatility in domestic markets. In this scope, we employ USV condition as a specification for affine term structure (AFTS) models. Comparing AFTS models with stochastic and constant volatility, we find that three-factor constant volatility model provides more robust estimation results in terms of both volatility and yield fitting.

The inflation-hedging properties of Turkish REITs
Erol, Işıl; Tirtiroglu, Dogan (Informa UK Limited, 2008-01-01)
This study empirically tests the inflation-hedging abilities of Turkish REITs in comparison to the indices of common stocks listed on the Istanbul Stock Exchange (ISE) over the period December 1999 to December 2004. Two main factors motivate this study. First, compared to their counterparts in developed capital markets, Turkish REITs have some important tax incentives as well as flexibility in managing their portfolios. Second, the Turkish economy provides a rare and good opportunity to test the hedging beh...
A Closer look at mutual fund performance in Turkey based on active peer benchmarks
Şanap, Aybars Furkan; Küçükkaya, Halit Engin; Department of Business Administration (2017)
This master's thesis aims to evaluate mutual fund performance in Turkey on a risk-adjusted basis with various approaches. First, commonly used Capital Asset Pricing Model (CAPM) and Carhart Four-Factor Model are employed for performance analysis. Then, active peer benchmarks (APB) are utilized to account for market-capitalization characteristics of portfolio stockholdings and to control commonalities in unsystematic risk-taking of different mutual funds. The empirical results are mixed for the sampled fifty...
Investigating the effects of illiquidity on credit risks via new liquidity augmented stochastic volatility jump diffusion model
Gaygısız Lajunen, Esma; Hekimoglu, Alper (2021-12-01)
Liquidity is extremely important not only within the context of financial markets but also in every scale of economic transactions. In this study, within the realm of financial markets, we configure liquidity as an independent stochastic process moderating the fluidity of all transactions and hence dynamically changing asset values. This study's asset value process ignoring liquidity is modelled with a stochastic volatility jump-diffusion (SVJ) model and that model is augmented with the incorporation of a l...
A strength-biased prediction model for forecasting exchange rates using support vector machines and genetic algorithms
Ozorhan, Mustafa Onur; Toroslu, İsmail Hakkı; Şehitoğlu, Onur Tolga (2017-11-01)
This paper addresses problem of predicting direction and magnitude of movement of currency pairs in the foreign exchange market. The study uses Support Vector Machine with a novel approach for input data and trading strategy. The input data contain technical indicators generated from currency price data (i.e., open, high, low and close prices) and representation of these technical indicators as trend deterministic signals. The input data are also dynamically adapted to each trading day with genetic algorith...
An Empirical Analysis of the Bank Lending Channel in Turkey
Ozsuca, Ekin Ayse; Akbostancı Özkazanç, Elif (2013-07-01)
The purpose of this paper is to empirically analyze the role of the banking sector in monetary policy transmission in Turkey covering the period 1988-2009. By exploiting dynamic panel data modeling approaches, the heterogeneity in banks' lending response to changes in policy interest rates is analyzed. Given the changes in the policy stance and developments in the financial system following the 2000-01 crisis, the analysis is further conducted for the two sub-periods, 1988-2001 and 2002-2009, to examine whe...
