THE COST STRUCTURE OF MICROFINANCE INSTITUTIONS IN EASTERN EUROPE AND CENTRAL ASIA

Microfinance institutions are important, particularly in developing countries, because they expand the frontier of financial intermediation by providing loans to those traditionally excluded from formal financial markets. This paper presents the first systematic statistical examination of the performance of MFIs operating in Eastern Europe and Central Asia. A cost function is estimated for MFIs in the region from 1999-2004. First, the presence of subsidies is found to be associated with higher MFI costs. When output is measured as the number of loans made, we find that MFIs become more efficient over time and that MFIs involved in the provision of group loans and loans to women have lower costs. However, when output is measured as volume of loans rather than their number, this last finding is reversed. This may be due to the fact that such loans are smaller in size; thus for a given volume more loans must be made.http://deepblue.lib.umich.edu/bitstream/2027.42/40195/3/wp809.pd

Effizienz und Wettbewerb im deutschen Bankensektor

In diesem Papier geben wir einen Überblick über den Wettbewerb und die Effizienz im deutschen Bankensektor. Wir nehmen dabei die Entwicklung in den letzten 15 Jahren in den Blick. Frühere Studien für Deutschland weisen darauf hin, dass das deutsche Bankensystem durch monopolistische Konkurrenz und durch moderat hohe Kosteneffizienz gekennzeichnet ist. Zudem scheinen Wettbewerb und Effizienz positiv miteinander verbunden. Des weiteren bestanden deutliche Unterschiede zwischen großen und kleinen Banken. Kleine Banken bevorzugten mehr das traditionelle Bankgeschäft, geringere Risiken und haben eher auf regional segmentierten Märk ten agiert. Die gegenwärtige Krise könnte zu tieferen Änderungen im Bankensystem führen, mit möglichen Folgen für Wettbewerb und Effizienz.In this paper we review the main findings on competition and efficiency for the German banking sector. Our aim is to give a bird view of the evolution during the past 15 years. Previous studies on Germany point to a banking system dominated by monopolistic competition and moderate cost efficiency. Competition and efficiency seem to be positively related. Furthermore significant differences existed between small and large banks. The business model of small banks was often more traditional, they preferred less risk and they acted on more segmented regional markets. The current crisis may lead to deep changes of the banking system, potentially with consequences for competition and efficiency

The Threat of Capital Drain: A Rationale for Public Banks?

This paper yields a rationale for why subsidized public banks may be desirable from a regional perspective in a financially integrated economy. We present a model with credit rationing and heterogeneous regions in which public banks prevent a capital drain from poorer to richer regions by subsidizing local depositors, for example, through a public guarantee. Under some conditions, cooperative banks can perform the same function without any subsidization; however, they may be crowded out by public banks. We also discuss the impact of the political structure on the emergence of public banks in a political-economy setting and the role of interregional mobility

Fintech governance and performance: Implications for banking and financial stability

This paper explores the relationship between governance and performance of Fintech firms recalling Resource-Based View and Upper Echelons Theory principles. Using a pooling model, we identify key characteristics of Chief Executive Officers (CEOs) and Boards of Directors (BoDs) that can improve profitability and lower risk in Fintech firms. The findings highlight that an older BoD increases risk and profitability, while a larger BoD reduces returns and risk. Furthermore, having a female CEO impacts the likelihood of default, while CEOs with expertise in management or law are associated with lower profitability. The study provides empirical evidence that governance structures can decrease Fintech risk and increase financial stability, addressing a previously overlooked research area. Informed decisions by banks about Fintech partnerships, based on enhanced governance, can mitigate risks, and improve the overall stability of the financial system

The COMPASS Experiment at CERN

The COMPASS experiment makes use of the CERN SPS high-intensitymuon and hadron beams for the investigation of the nucleon spin structure and the spectroscopy of hadrons. One or more outgoing particles are detected in coincidence with the incoming muon or hadron. A large polarized target inside a superconducting solenoid is used for the measurements with the muon beam. Outgoing particles are detected by a two-stage, large angle and large momentum range spectrometer. The setup is built using several types of tracking detectors, according to the expected incident rate, required space resolution and the solid angle to be covered. Particle identification is achieved using a RICH counter and both hadron and electromagnetic calorimeters. The setup has been successfully operated from 2002 onwards using a muon beam. Data with a hadron beam were also collected in 2004. This article describes the main features and performances of the spectrometer in 2004; a short summary of the 2006 upgrade is also given.Comment: 84 papes, 74 figure

Business model and ESG pillars: The impacts on banking default risk

The recent banks' failures have highlighted the importance of improving banking sector supervision, emphasizing the need to adopt a holistic approach to risk assessment based on an evaluation of a bank's business model (BBM) that combines financial (e.g., bank's balance data) and non-financial information (e.g., bank's ESG performance). In this study, we explore the joint effect of BBM and their environmental (ENV), social (SOC), and governance (GOV) pillars performance on banks' riskiness profile. The study uses a sample of 639 EU banks from 2013 to 2022 and applied a random effects model. Our findings suggest wholesale and retail banks could mitigate default risk, enhancing their ENV pillar performance. Differently, investment banks are encouraged to improve their governance best practices and structure to take advantage in terms of riskiness reduction. These results remain consistent after a series of robustness tests, including the 2SLS model and the Arellano coefficient estimation. Our paper offers practical implications for banking supervisory authorities and practitioners, encouraging to adopt a diversified ESG investment strategy according to bank-specific business models

Measurement of the Spin Structure of the Deuteron in the DIS Region

We present a new measurement of the longitudinal spin asymmetry A_1^d and the spin-dependent structure function g_1^d of the deuteron in the range 1 GeV^2 < Q^2 < 100 GeV^2 and 0.004< x <0.7. The data were obtained by the COMPASS experiment at CERN using a 160 GeV polarised muon beam and a large polarised 6-LiD target. The results are in agreement with those from previous experiments and improve considerably the statistical accuracy in the region 0.004 < x < 0.03.Comment: 10 pages, 6 figures, subm. to PLB, revised: author list, Fig. 4, details adde

Transverse Spin Structure of the Nucleon through Target Single Spin Asymmetry in Semi-Inclusive Deep-Inelastic (e,e′π±)(e,e^\prime \pi^\pm) Reaction at Jefferson Lab

Jefferson Lab (JLab) 12 GeV energy upgrade provides a golden opportunity to perform precision studies of the transverse spin and transverse-momentum-dependent structure in the valence quark region for both the proton and the neutron. In this paper, we focus our discussion on a recently approved experiment on the neutron as an example of the precision studies planned at JLab. The new experiment will perform precision measurements of target Single Spin Asymmetries (SSA) from semi-inclusive electro-production of charged pions from a 40-cm long transversely polarized $^3$He target in Deep-Inelastic-Scattering kinematics using 11 and 8.8 GeV electron beams. This new coincidence experiment in Hall A will employ a newly proposed solenoid spectrometer (SoLID). The large acceptance spectrometer and the high polarized luminosity will provide precise 4-D ($x$, $z$, $P_T$ and $Q^2$) data on the Collins, Sivers, and pretzelocity asymmetries for the neutron through the azimuthal angular dependence. The full 2$\pi$ azimuthal angular coverage in the lab is essential in controlling the systematic uncertainties. The results from this experiment, when combined with the proton Collins asymmetry measurement and the Collins fragmentation function determined from the e$^+$e$^-$ collision data, will allow for a quark flavor separation in order to achieve a determination of the tensor charge of the d quark to a 10% accuracy. The extracted Sivers and pretzelocity asymmetries will provide important information to understand the correlations between the quark orbital angular momentum and the nucleon spin and between the quark spin and nucleon spin.Comment: 23 pages, 13 figures, minor corrections, matches published versio

The risk‐taking channel in the United States : A GVAR approach

Using a panel of large U.S. banks, we examine banks' risk‐taking behaviour in response to monetary policy shocks. Our investigation provides support for the presence of a risk‐taking channel: banks' non‐performing loans increase in the medium to long‐run following an expansionary monetary policy shock. We also find that banks' capital structure plays an important role in explaining bank's risk‐taking appetite. Impulse response analysis shows that shocks emanating from larger banks spill over to the rest of the sector but no such effect is observed for smaller banks. These findings are confirmed for banks' Z‐score

The impact of deregulation and re-regulation on bank efficiency: evidence from Asia

Following the 1997 crisis, banking sector reforms in Asia have been characterised by the emphasis on prudential regulation, associated with increased financial liberalisation. Using a panel data set of commercial banks from eight major Asian economies over the period 2001-2010, this study explores how the coexistence of liberalisation and prudential regulation affects banks’ cost characteristics. Given the presence of heterogeneity of technologies across countries, we use a stochastic frontier approach followed by the estimation of a deterministic meta-frontier to provide ‘true’ estimates of bank cost efficiency measures. Our results show that the liberalization of bank interest rates and the increase in foreign banks' presence have had a positive and significant impact on technological progress and cost efficiency. On the other hand, we find that prudential regulation might adversely affect bank cost performance. When designing an optimal regulatory framework, policy makers should combine policies which aim to foster financial stability without hindering financial intermediation
