This paper develops and estimates a dynamic model of consumer demand for deposits, in which banks provide di¤erentiated products, and product characteristics evolve over time. Consumers choose their banks based on the utility received from using their services, and incur a …xed cost when they switch banks. Consequently, consumer choices include which bank to use and when to switch. Utilizing th...

Bank is one of the example of institute that using Information Technology (IT) in its daily task to fulfill the organization’s and customers’ need. Business transaction, money transfer, ATM, credit card, and loan are some tasks that were done every day. Customers’ personal information stored by the bank is also considered as private and should not be disclose to anybody with no authorization. O...

To test if simultaneous spectral and temporal processing is required to extract robust features for automatic speech recognition (ASR), the robust spectro-temporal two-dimensional-Gabor filter bank (GBFB) front-end from Schädler, Meyer, and Kollmeier [J. Acoust. Soc. Am. 131, 4134-4151 (2012)] was de-composed into a spectral one-dimensional-Gabor filter bank and a temporal one-dimensional-Gabor...

News is a pertinent source of information on financial risks and stress factors, which nevertheless is challenging to harness due to the sparse and unstructured nature of natural text. We propose an approach based on distributional semantics and deep learning with neural networks to model and link text to a scarce set of bank distress events. Through unsupervised training, we learn semantic vec...

In this paper, various algorithms for designing quadrature mirror filter are reviewed and a new algorithm is presented for the design of near perfect reconstruction quadrature mirror filter bank. In the proposed algorithm, objective function is formulated using the perfect reconstruction condition or magnitude response condition of prototype filter at frequency (ω = 0.5π) in ideal condition. Th...

We examine the role of macroeconomic ‡uctuations, asset market liquidity, and network structure in determining contagion and aggregate losses in a …nancial system. Systemic instability is explored in a …nancial network comprising three distinct, but interconnected, sets of agents – domestic banks, international …nancial institutions, and …rms. Calibrating the model to advanced country banking s...

It is a well documented empirical fact that …rm level investment is lumpy rather than smooth. In the present paper we …nd that the aggregate consequences of lumpy investment in general equilibrium are quantitatively important. Earlier results stressing the irrelevance of lumpy investment in general equilibrium are therefore an artefact of assuming perfect competition combined with fully ‡exible...

The aim of this paper is to estimate the efficiency of the Slovak commercial banks employing the Data Envelopment Analysis (DEA) window analysis approach during the period 20032012. The research is based on unbalanced panel data of the Slovak commercial banks. Undesirable output was included into analysis of banking efficiency. It was found that most efficient banks were Postovabanka, UniCredit...

In this paper, the detection of a fault in the Global Positioning System (GPS) measurement is addressed. The class of faults considered is a bias in the GPS pseudorange measurements. This bias is modeled as an unknown constant. The fault could be the result of a receiver fault or signal fault such as multipath error. A bias bank is constructed based on set of possible fault hypotheses. Initiall...
