Early warning of systemic risk in global banking: eigen-pair R number for financial contagion and market price-based methods
2021
AbstractWe analyse systemic risk in the core global banking system using a new network-based spectral eigen-pair method, which treats network failure as a dynamical system stability problem. This is compared with market price-based Systemic Risk Indexes (SRIs), viz. Marginal Expected Shortfall (MES), Delta Conditional Value-at-Risk (Delta-CoVaR), and Conditional Capital Shortfall Measure of Systemic Risk (SRISK) in a cross-border setting. Unlike paradoxical market price based risk measures, which underestimate risk during periods of asset price booms, the eigen-pair method based on bilateral balance sheet data gives early-warning of instability in terms of the tipping point that is analogou…
ICT Barriers and Critical Success Factors in Developing Countries
2013
Since the early 1990s, Information and Communication Technology (ICT) has been perceived as a catalyst for development. However, the UNICEF State of the World’s Children Report 2011 acknowledges that the poor in many developing countries remain largely excluded from ICT and its benefits. This paper aims to address three issues. Firstly, identify ICT barriers in the literature from 2000 to 2011. Secondly, identify ICT barriers through empirical findings and thirdly, categorize these barriers into critical success factors. These aims are achieved by comparing the findings in the literature to our recent empirical results. Two methodologies are used in this study, namely, a systematic literatu…
The Value Relevance of Risk Disclosure: An Analysis of the Banking Sector
2020
The aim of this study is to test whether financial risk disclosures required by IFRS 7 and Pillar 3 are value relevant for investors to support them in their investment decisions. The sample in the...
Layering of IFRS and Dual Institutionality of Accounting Standards in Belarus
2017
Submitted version of an article published in the journal Accounting in Europe. There is an ongoing debate about the applicability and efficacy of International Financial Reporting Standards (IFRS) adoption in countries with diverse institutional infrastructures. We examine financial reporting in Belarus and factors that are shaping its development. In Belarus, IFRS has been adopted through layering where it is an additional requirement to the existing reporting specified by the national accounting regulations. We explore how global standards were transposed and function in a highly specific institutional context. Based on an examination of reporting in the banking sector, we conclude that d…
Banks’ business strategies on the edge of distress
2019
AbstractThe paper investigates the importance of banks’ business classification in shaping the risk profile of financial institutions on a global scale. We employ a rare-event logit model based on a state-of-the-art list of major global distress events from the global financial crisis. When clustering banks by their business strategies using a community detection approach, we show that (i) capital enhanced resilience only for traditional banks that were on average less capitalized than other banks; (ii) boosting ROE, usually associated with riskier exposures, improved resilience for stable funded and asset diversified banks; (iii) conversely, higher levels of ROA exacerbated banks’ vulnerab…
Using a hazard-independent approach to understand road-network robustness to multiple disruption scenarios
2021
Abstract A range of predictable and unpredictable events can cause road perturbations, disrupting traffic flows and more generally the functioning of society. To manage this threat, stakeholders need to understand the potential impact of a multitude of predictable and unpredictable events. The present paper adopts a hazard-independent approach to assess the robustness (ability to maintain functionality despite disturbances) of the Sioux Falls network to all possible disruptions. This approach allows understanding the impact of a wide range of disruptive events, including random, localised, and targeted link failures. The paper also investigates the predictability of the link combinations wh…
Signaling Reduction in 5G eV2X Communications Based on Vehicle Grouping
2019
Groups of users, sometimes referred to as clusters, have been exploited in several works to enhance wireless communications. Leveraging on previous ideas, the main goal of this paper is to take advantage of vehicle grouping in order to reduce uplink signaling in fifth generation (5G) vehicular communications. Several schemes to reduce uplink signaling are proposed and particularized in two specific 5G uses cases: the reporting of Channel Busy Ratio (CBR), and the reporting of beam measurements in beam management procedures. The achieved signaling reduction is analytically evaluated in an example of urban scenario with high vehicle densities for different group sizes. The signaling load can …
Simplified restructuring proceedings in Poland as an example of anti – crisis regulation due to the COVID-19 pandemic
2020
Summary The study discusses new legislative anti – crisis solutions adopted in Poland in connection with the COVID – 19 pandemic. The Polish legislator decided to introduce the so-called simplified restructuring procedure. This happened in the face of the expectations of both the jurisprudence of law and practice. On the one hand, the simplified restructuring procedure (the fifth independent type of restructuring procedure for an entrepreneur in Poland) allows for a quick, cheap and simplified conclusion of an arrangement with creditors outside the court, then approved by the court. On the other hand, the opening of such proceedings gives the debtor protection against enforcement at the cre…
Zastosowanie metody AHP do tworzenia rankingu kryteriów oceny wiarygodności witryn internetowych
2020
Wiedza w zakresie pozyskiwania, oceny i efektywnego wykorzystania informacji jest niezbędna nie tylko uczniom, studentom i nauczycielom (w tym akademickim), ale także projektantom i twórcom witryn oraz dostawcom treści internetowych. W szczególności dotyczy to możliwości oceny wiarygodności witryn internetowych. Problemem jest nie tylko wybór odpowiednich kategorii i kryteriów tej oceny, ale także uwzględnienie wszystkich tych kryteriów w końcowej ocenie. Celem artykułu jest ustalenie rankingu ważności kryteriów oceny wiarygodności witryn internetowych z punktu widzenia ekspertów. Wymagało to udzielenia odpowiedzi na następujące pytania: - Jak stworzyć ramy oceny wiarygodności witryn? - Któ…
Another "French paradox": explaining why interest rates to microenterprises dit not increase with the change in French usury legislation
2015
Conventional wisdom indicates that the growth of credit may not materialize if credit rates remain capped by usury laws, as had long been the case in France. France therefore abolished usury ceilings on loans to microenterprise in an effort to increase financing for microentrepreneurs. This should have led to an increase in interest rates and increase in microcredit. However, we do not find any increase in interest rates and this is therefore a paradox. The paper provides a brief literature review and the salient features of the legislative changes in France. It follows this up with a presentation of interest rate movements. The discussion of possible explanations of the paradox includes cl…
