This study aims to test the validity of the Rajan theory in South Africa and other selected emerging markets (Chile, Peru and Brazil) during the period 1975–2019.

In this study, the researchers used time-series data to estimate a Bayesian Vector Autoregression (BVAR) model with hierarchical priors. The BVAR technique has the advantage of being able to accommodate a wide cross-section of variables without running out of degrees of freedom. It is also able to deal with dense parameterization by imposing structure on model coefficients via prior information and optimal choice of the degree of formativeness.

The results for all countries except Peru confirmed the Rajan hypotheses, indicating that inequality contributes to high indebtedness, resulting in financial fragility. However, for Peru, this study finds it contradicts the theory. This study controlled for monetary policy shock and found the results differing country-specific.

The findings suggest that an escalating level of inequality leads to financial fragility, which implies that policymakers ought to be cautious of excessive inequality when endeavouring to contain the risk of financial fragility, by implementing sound structural reform policies that aim to attract investments consistent with job creation, development and growth in these countries. Policymakers should also be cautious when implementing policy tools (redistributive policies, a sound monetary policy), as they seem to increase the risk of excessive credit growth and financial fragility, and they need to treat income inequality as an important factor relevant to macroeconomic aggregates and financial fragility.

Validation of the Teachers' Sense of Efficacy Scale (TSES) for use with teachers in Macao (SAR) was undertaken to determine its usefulness as a measure of teacher self-efficacy for inclusive education. This paper discusses the results found by analyzing various versions of the TSES and TSES-C in a Chinese format with 200 pre-service teachers in Macao (SAR). Psychometric analyses were undertaken to investigate the validity of the existing scales and the three and two factor solutions. The results indicated a preferred 9-item version that produced improved factor loadings and reliabilities. The use of a relatively quick and short scale to measure such a complex phenomenon as teacher self-efficacy is discussed. Issues are raised regarding generalizability of scales and the impact of culture, demographics, and edifying issues that may impact on the usefulness of such scales.

This study aims to examine whether the internal locus of control, self-esteem and leadership self-efficacy can predict differences in self–other rating agreement on leader effectiveness. First, the authors predicted that the greater the internal locus of a leader the more their self-rating will be in agreement with others' rating of them (1a). Second, the authors proposed that the greater the self-esteem of a leader the more their self-rating will be in discrepancy with others' rating (1b). Third, the authors hypothesized that the greater the self-efficacy of a leader the more their self-rating will be in agreement with others' rating (1c).

To test the hypotheses, multisource data were collected from 128 banking leaders (who responded about different aspects of leadership self-efficacy, internal locus of control, self-esteem and leadership effectiveness) and 344 subordinates (who rated their leaders' effectiveness in performing leadership tasks).Multivariate regression was performed by jointly regressing both leaders' self-ratings and subordinates' ratings as a dependent variable on internal locus of control, self-esteem and leadership self-efficacy as predictor variables.

Self-esteem of a leader the more their self-rating will be in discrepancy with others' ratings.

The study tried to investigate the leader-subordinate dis(agreement) on leaders’ effectiveness taking banking leaders in the Ethiopian Context. The finding of the results is crucial and important for leadership development programs.

The paper aims to disentangle the physiological credit risk from the credit risk coming from the inefficient screening and monitoring management process. The analysis is conducted on a sample of 338 Italian banks–56 joint-stock banks (SpA), 23 cooperative banks (Popolari) and 259 mutual banks (BCCs)–over the time period 2006–2017.

The authors use the maximum likelihood method to estimate the efficient frontier, as a set of best management credit practices, which minimises the credit risk defined on the basis of the level of loans granted, the technical structure of the loan portfolio (such as credit lines, mortgages, consumer loans and other technical loan categories) and the interest rate charges.

The empirical results show that the increase in non-performing loans (NPLs) is related both to the severe and protracted recession in Italy, which significantly reduced borrowers' capacity to service their debt, and to other factors, such as banks' lending monitoring policies with limited capacity to work-out defaulted loans.

The authors propose a new approach to the study of the performance of the credit process. With the stochastic frontier, the physiological credit risk, assumed by the bank according to its lending activity and management choices, is separated from the credit risk resulting from an inefficient management of the screening and monitoring process. In addition, the authors analyse the determinants of the excess of NPLs. This aspect is considered particularly original because the scientific contributions which consider the causes of NPLs have largely focused on the level of NPLs not considering the physiological part, linked to the structure of the bank's loan portfolio and its operational strategy and therefore not compressible and in any case not attributable to mismanagement or moral hazard.

Why are some lean workfloor teams able to improve their already high performance, over time, and others not? By studying teams' and leaders' behaviour-value patterns, this abductive field study uncovers a dynamic capability at the team level.

Various methods were employed over three consecutive years to thoroughly examine five initially high-performing lean workfloor teams, including their leaders. These methods encompassed micro-behavioural coding of 59 h of film footage, surveys, individual and group interviews, participant observation and archival data, involving objective and perceptual team-performance indicators. Two of the five teams continued to improve and perform highly.

Continuously improving high lean team performance is found to be associated with (1) team behaviours such as frequent performance monitoring, information sharing, peer support and process improvement; (2) team leaders who balance, over time, task- and relations-oriented behaviours; (3) higher-level leaders who keep offering the team face-to-face support, strategic clarity and tangible resources; (4) these three actors' endorsement of self-transcendence and openness-to-change work values and alignment, over time, with their behaviours; and (5) coactive vicarious learning-by-doing as a “stable collective activity pattern” among team, team leader, and higher-level leadership.

Since lean has been undertheorised, the authors invoked insights from organisational behaviour and management theories, in combination with various fine- and coarse-grained data, over time. The authors uncovered actors' behaviour-value patterns and a collective learning-by-doing pattern that may explain continuous lean team performance improvement. Four theory-enriching propositions were developed and visualised in a refined model which may already benefit lean practitioners.

The growing availability of wireless internet services and the great popularization of smartphones and other mobile devices means a greater challenge for mobile service companies that need to identify the factors influencing the use behavior of mobile services. So considering that the level of consumer involvement can lead to differences in service outcome evaluations, this study aims to examine whether consumer involvement with information and communication technologies (ICTs) has a moderating influence on consumer behavior in mobile services

The authors propose an integrative model of the usage of mobile services to examine the moderating role of involvement with ICTs. Drawing on a sample of 493 users, two levels of involvement with ICTs were examined; and data were analyzed through multiple-group structural equation modeling.

Findings show that the level of consumer involvement with ICTs influences the behavior in the mobile services. Further, the findings support that mobile services’ perceived quality, followed by the service perceived value are the factors with a stronger influence in satisfaction with mobile services, regardless the level of consumer involvement with ICTs. However, the mobile company corporate image has a lower influence. In addition, the results support the partial moderating role of involvement with ICTs in the loyalty toward mobile service providers, suggesting that consumers lowly involved with ICTs experience a greater impact of the service quality on their loyalty.

The main contribution of this study is the examination of the influence of involvement with technologies in consumer behavior in the mobile services

La disponibilidad creciente de los servicios internet inalámbrico y la gran popularización y adopción de los smartphones y de otros dispositivos móviles supone un gran desafío para las compañías de servicios móviles que necesitan identificar aquellos factores que influyen en el comportamiento de uso de los servicios móviles. Así, considerando que el nivel de implicación del consumidor puede llevar a diferencias en las evaluaciones de los resultados de los servicios, este estudio analiza si la implicación del consumidor con las tecnologías de la información y la comunicación (TICs) tiene una influencia moderadora en el comportamiento del consumidor en los servicios móviles.

Se propone un modelo integrador sobre el uso de los servicios móviles para examinar el rol moderador de la implicación del consumidor con las TICs. Sobre la base de una muestra de 493 usuarios, se analizaron dos niveles de implicación con las TICs; y los datos fueron analizados mediante un modelo multigrupo de ecuaciones estructurales.

Los resultados muestran que el nivel de implicación del consumidor con las TIC influye en su comportamiento hacia los servicios móviles. Además, nuestros resultados respaldan que la calidad percibida de los servicios móviles, seguida del valor percibido de estos servicios son los factores con mayor influencia en la satisfacción con los servicios móviles, independientemente del nivel de implicación del consumidor con las TIC. Sin embargo, la imagen corporativa de la compañía de servicios móviles tiene una influencia menor. Adicionalmente, nuestros resultados muestran el rol moderador parcial de la implicación con las TIC en la lealtad hacia los proveedores de servicios móviles, sugiriendo que los consumidores poco implicados con las TIC experimentan un mayor impacto de la calidad del servicio en su lealtad.

La principal contribución de este estudio es el análisis de la influencia de la implicación del consumidor con las tecnologías, en su comportamiento hacia los servicios de comunicación móvil.
