The choice of monetary policy tool(s) and relative price variability: evidence from Turkey
Berument, Hakan; Sahin, A.; Saracoglu, B. (A N S I Network, 2009)The aim of this study is to assess any regularity relative price dispersion for the effect of monetary policy tool selection. Central banks use tools such as interbank rate and exchange rate when pursuing their (monetary) ... -
Day of the week effect on foreign exchange market volatility: evidence from Turkey
Berument, Hakan; Coskun, M. N.; Sahin, A. (Elsevier Inc., 2007)This paper assesses the day of the week effect of the daily depreciation of the Turkish lira (TL) against the US dollar (USD) and its volatility. The empirical evidence from Turkey presented here suggests that Thursdays ... -
Design of dynamically adjustable anamorphic fractional Fourier transformer
Erden, M. F.; Özaktaş, Haldun M.; Sahin, A.; Mendlovic, D. (Elsevier BV * North-Holland, 1997-03-01)We form optical systems by using only free space portions and cylindrical lenses, and consider these systems as anamorphic fractional Fourier transformers. We dynamically adjust the transform order, scale factor and field ... -
Effectiveness of the reserve option mechanism as a macroeconomic prudential tool: evidence from Turkey
Sahin, A.; Dogan, B.; Berument, Hakan (Routledge, 2015)This article assesses the effectiveness of a novel macroprudential tool – the reserve option mechanism (ROM) – which Turkey’s central bank developed during the post-2008 period and has employed to control the risk associated ... -
Identfying the liquidity effects of monetary policy shocks for a small open economy: Turkey
Berument, Hakan; Togay, S.; Sahin, A. (Springer New York LLC, 2011)This paper proposes a new liquidity measure for a small open economy. The new measure includes the net liquidity provided to the system by a central bank after accounting for the central bank's involvement in the foreign ... -
Nonseperable two-dimensional fractional Fourier transform
Sahin, A.; Kutay, M. A.; Özaktaş, Haldun M. (Optical Society of America, 1998)Previous generalizations of the fractional Fourier transform to two dimensions assumed separable kernels. We present a nonseparable definition for the two-dimensional fractional Fourier transform that includes the separable ... -
Optical implementation of the two-dimensional fractional Fourier transform with different orders in the two dimensions
Sahin, A.; Özaktaş, Haldun M.; Mendlovic, D. (Elsevier BV * North-Holland, 1995-10-15)Previous optical implementations of the two-dimensional fractional Fourier transform have assumed identical transform orders in both dimensions. We let the orders in the two orthogonal dimensions to be different and present ... -
Optical implementations of two-dimensional fractional Fourier transforms and linear canonical transforms with arbitrary parameters
Sahin, A.; Özaktaş, Haldun M.; Mendlovic, D. (Optical Society of America, 1998-04-10)We provide a general treatment of optical two-dimensional fractional Fourier transforming systems. We not only allow the fractional Fourier transform orders to be specified independently for the two dimensions but also ... -
The relative effects of crude oil price and exchange rate on petroleum product prices: evidence from a set of Northern Meditteranean countries
Berument, Hakan; Sahin, A.; Sahin, S. (Elsevier, 2014)This paper provides a set of empirical evidence from five Northern Mediterranean countries that are subject to similar refinery reference prices regarding the relative sensitivity of crude oil prices and exchange rate ... -
RuO2 supercapacitor enables flexible, safe, and efficient optoelectronic neural interface
Karatum, O.; Yildiz, E.; Kaleli, H. N.; Sahin, A.; Ulgut, Burak; Nizamoglu, S. (Wiley-VCH Verlag GmbH & Co. KGaA, 2022-08-01)Optoelectronic biointerfaces offer a wireless and nongenetic neurostimulation pathway with high spatiotemporal resolution. Fabrication of low-cost and flexible optoelectronic biointerfaces that have high photogenerated ... -
Seasonal patterns of inflation uncertainty for the US economy: an EGARCH model results
Berument, Hakan; Kose, N.; Sahin, A. (IUP Publications, 2010)The purpose of this paper is to assess the seasonal inflation uncertainties for a big open economy, the US, for the period from January 1947 to April 2008. The paper uses EGARCH model which includes volatility in the ... -
Seasonality in inflation volatility: evidence from Turkey
Berument, Hakan; Sahin, A. (Universidad del CEMA, 2010)This paper assesses the presence of seasonal volatility in price indexes where a similar type of pattern has been reported in asset prices in financial markets. The empirical evidence from Turkey for the monthly period ...
