This study proposes a political interference hypothesis to explain how political considerations depress government banks performance. In here, we define the political interference as the situation in which the executives of government banks are replaced within 12 months after the presidential elections. We classify government banks into political and non-political banks when the government bank...

This tutorial reviews the theory, structure and design methods for M-channel perfect-reconstruction (PR) lter banks. Some of the lter banks being considered here are the two-channel orthogonal lter bank; biorthogonal linear-phase lter banks; M-channel cosine-modulated lter banks and M-channel linear-phase lter banks. The connection with wavelet transform will be elaborated on the case of discre...

We study an oligopoly model of banking that allows us to evaluate the two leading explanations for banks’ ability to earn rents. In the model, banks can either invest in information acquisition, or in market power (through product differentiation). The two versions generate different predictions that are tested using panel data on Finnish local banks. We find that banks’ investments in branch n...

This paper explores the issue of banking efficiency in Central Europe by applying the Fourier functional form and the stochastic cost frontier approach in calculating inefficiencies for a large sample of German, Austrian, Swiss and Luxembourg banks between 1997 and 2003. The findings suggest that the largest sized banks are generally the least efficient banks and the smallest sized banks are th...

This paper addresses a polyphase structure of spectral graph wavelets and filter banks. We consider two-channel critically sampled graph filter banks. In classical signal processing, polyphase structure of filter banks is very useful since downsampler (upsampler) can be placed before analysis filtering (after synthesis filtering). We theoretically derive that a similar structure is also possibl...

In this paper we investigate whether banks that borrow from other banks have lower risk levels. We concentrate on a large sample of Central and Eastern European banks which allows us to explore the impact of interbank lending when exposures are long-term and interbank borrowers are small banks. The results of the empirical analysis generally confirm the hypothesis that long-term interbank expos...

This paper examines the internationalisation of Chinese state-owned commercial banks in London's financial centre from 2010s onwards. These have transformed primarily servicing enterprises to making up four largest globally by balance sheet and undertaking a range operations including RMB clearing cross border settlement yet their future international trajectory remains uncertain. My analysis p...

We define the notion of almost $n$-layered $QTAG$-modules and study their basic properties. One of the main result is that almost 1-layered modules are almost $(omega+1)$-projective exactly when they are almost direct sum of countably generated modules of length less than or equal to $(omega+1)$. Some other characterizations of this new class are also established.

This review reports recent advances in the field of polymer–layered silicate nano composites. Thesematerials have attracted both academic and industrial attention because they exhibit dramaticimprovement in properties at very low filler contents. Herein, the structure, preparation andproperties of polymer–layered silicate nanocomposites are discussed in general, and finally the effectof clay na...

SN SOME of its public statements in recent years, the Federal Deposit Insurance Corporation (FDIC) has stressed the objective of promoting market discipline of the risks assumed by banks through the influence of uninsured depositors.’ The FDIC has attempted to accomplish this by allowing the uninsured depositors of some failed banks to suffer losses. In practice, the cases in which uninsured de...
