This paper presents an efficient method for the design of two-channel quadrature mirror filter (QMF) bank by polyphase representation of low-pass prototype filter and power optimization method for minimization of an objective function. The objective function is formulated as linear combination of pass-band error and stop-band residual energy of the low-pass analysis filter of the filter bank. O...

One of the most significant threats to the economy of a nation is the bankruptcy of its banks. This study evaluates the susceptibility of Nigerian banks to failure with a view to identifying ratios and financial data that are sensitive to solvency of the bank. Further, a predictive model is generated to guide all stakeholders in the industry. Thirty quoted banks that had published Annual Report...

When expanding abroad, a multinational bank faces a trade-o¤ between accessing a foreign country via cross border lending or a …nancial foreign direct investment, i.e. green…eld or acquisition entry. We analyze the entry mode choice of multinational banks and explicitly derive the entry mode pattern in the banking industry. Moreover, we show that in less developed banking markets, a trend towar...

We show that a competitive banking system is inconsistent with an optimum quantity of private money. Because bankers cannot commit to their promises and the composition of their assets is not publicly observable, a positive franchise value is required to induce the full convertibility of bank liabilities. Under perfect competition, a positive franchise value can be obtained only if the return o...

We propose a theoretical model based on the bank lending channel to assess the ability of lending facilities and swap programmes to a¤ect the credit interest rate. The model predicts the success of both unconventional monetary measures in reducing the credit interest rate under very general conditions. The comparison between measures reveals the outperformance of lending facilities over swap pr...

We show that the regulation of bank lending practices is necessary for the optimal provision of private liquidity. In an environment in which bankers cannot commit to repay their creditors, we show that neither an unregulated banking system nor narrow banking can provide the socially e¢ cient amount of liquidity. If the bankers provided such an amount, then they would prefer to default on their...
