A new fair electronic cash system is proposed based on group blind signature and secret sharing scheme. Our proposed system is dynamic: we propose a method to delete the dishonest banks that maybe attack the system, which was not mentioned in the previous literatures. Our proposed scheme does not need a trusted third party to trace users: a shop owning suspicious ecoin and the bank having issue...

An unrelentingly challenging business environment has also prompted corporate banking clients to take measures to ensure that they have an efficient working-capital ecosystem to support their local treasuries. This trend is also forcing banks to consider new transaction banking models, especially around cost optimization. These circumstances have made e-invoicing an increasingly popular topic o...

Electronic purse systems can be an alternative for cash payments as well as PIN payments or credit card payments. For retailers as well as banks, this is attractive for reasons of cost and speed. One common system seems feasible, but in The Netherlands there have been two competing systems for several years. The common banks started with one system, but one of these banks introduced a competing...

Several theoretical studies suggest that only uninsured depositors have an incentive to discipline their banks, i. e. react with changes in deposit volumes or in required interest rates as a reaction to changes in banks’ risk. This paper empirically investigates whether German savings banks are disciplined by their depositors although these should be regarded as fully insured due to public guar...

This paper analyses structural and cyclical determinants of banking profitability in 16 Western European countries. We find that financial structure matters, particularly through the beneficial effect of the capital market orientation in the respective national financial system. Furthermore, higher diversification regarding banks’ income sources shows a positive effect. The industry concentrati...

1. Introduction and Executive Summary This paper analyses the role of the central bank in the modern world, focusing in particular on its involvement in the payments and …nancial systems. I provide an overview of the functions of central banks. I then focus on the role of the central banks in promoting an e¢ cient payments system and I disucuss their role in supervising and regulating the payme...

We present a model of …nancial crises that stem from endogenous complexity. We conceptualize complexity as banks’uncertainty about the …nancial network of cross-exposures. As conditions deteriorate, cross-exposures generate the possibility of a domino e¤ect of bankruptcies. As this happens, banks face an increasingly complex environment since they need to understand a greater fraction of the …n...

Due to the burgeoning development of electronic commerce (e-commerce),the broader applications of emerging service—Internet baking (e-banking) services have been introduced and provided by financial holding companies or banks at an accelerating rate in recent years since they can provide efficient, reliable, securable, and convenient financial services, such as online payment, deposit/loan, tra...

Wavelet and short-time Fourier analysis is introduced in the context of frequency decompo-sitions. Wavelet type frequency decompositions are associated with lter banks, and using thisfact, lter bank theory is used to construct multiplicity M wavelet frames and tight frames. Theway in which lter banks lead to decomposition and recomposition of arbitrary separable Hilbertspaces is...

Banks use over-the-counter derivative (OTCD) contracts for sharing the risks of their asset streams. OTCDs are composed of an optimal combination of interbank loans, asset swaps and credit default swaps (CDS). The settlement of ex-post realized claims are renegotiated by participating banks after defaults by one or more banks to minimize the systemic impact of the default. The bailout by a solv...
