Purpose: The study aims to compare the credit risk minimization between Islamic and conventional banks in Yemen. Approach/Methodology/Design: This paper is limited a homogeneous sample that includes banks' coverage as they represent most significant part of Yemeni banking sector. Using descriptive-analytical method, data has been collected by questionnaire sent post each bank separately located...

Development of E-banking has modified the structure of banking business and banking performance, efficiency, risk and challenges which have also been articulately recognized based on the international best practices. E-banking brazenly expedites and streamlines financial transactions via enhancing technology and expanding the bank services in comparison with conventional banking. Accordingly, o...

This paper concerns the construction of highly symmetric compactly supported wavelets for hexagonal data/image and triangle surface multiresolution processing. Recently hexagonal image processing has attracted attention. Compared with the conventional square lattice, the hexagonal lattice has several advantages, including that it has higher symmetry. It is desirable that the filter banks for he...

The views expressed in this Working Paper are those of the author(s) and do not necessarily represent those of the IMF or IMF policy. Working Papers describe research in progress by the author(s) and are published to elicit comments and to further debate. This study examines how depositors decide among different banks and over time in Colombia, with particular attention to the issue of market d...

A new approach to implement computationally efficient reconfigurable filter banks for software defined radio receivers is presented in this paper. If the coefficients of a finite impulse response (FIR) filter are decimated by M, i.e., if every M-th coefficient of the filter is kept unchanged and remaining coefficients are replaced by zeros, a multi-band frequency response will be obtained. The ...

We design lter banks that are best matched to input signal statistics in M-channel sub-band coders, using a rate{distortion criterion. Recent research has shown that unconstrained{ length paraunitary lter banks optimized under various energy compaction criteria are principal-component lter banks and satisfy two fundamental properties: total decorrelation and spectral majorization. We present se...

We show that in stark contrast to conventional wisdom, maturity transformation does not expose banks to significant interest rate risk. Aggregate net interest margins have been near-constant over 1955–2013, despite substantial maturity mismatch and wide variation in interest rates. We argue that this is due to banks’ market power in deposit markets. Market power allows banks to pay deposit rate...
