Agency Conflict and Bank Interest Spreads in Ghana

Abstract: This study examines the relationship between interest rate spreads in the Ghanaian banking industry and variables that reflect convergence/divergence between managerial goals and corporate goals of which the key variables are executive compensation and bank ownership structure. Using data covering the period 1999–2011, this study employs a panel regression to examine how agency factors affect interest rate spreads in Ghana. The results of the study indicate that executive compensation is associated with higher net interest margins, suggesting that managers operate on higher margins since they can extract excess rents. The findings of the study also show that asset size, the level of concentration in the banking industry, the level of capital held by banks, the reserve requirement, and the level of inflation all positively contribute to the observed high interest spreads. Our results are robust to the control of several bank-specific, industry-specific, regulatory and macroeconomic factors.

Predicting corporate failure: some empirical evidence from the UK

Abstract: Purpose – The purpose of this paper is to use relevant financial information of private medium‐sized failed and non‐failed manufacturing firms in the UK, during the period 1994‐2004 to determine whether corporate failure can be predicted by developing a Z‐score model.Design/methodology/approach – Multiple discriminant analysis is used to develop the Z‐score to support the notion that Z‐score is an innovation to overcome the numerous difficulties associated with using single ratios to measure companies' health or risk of failure.Findings – This paper advances the notion that the net profit margin is superior to the gross profit margin in discriminating between failed and non‐failed UK manufacturing companies in terms of its significant contribution to the Z‐score, though the latter exceeds the former slightly using the univariate analysis.Originality/value – This research contributes to the area of benchmarking by providing a method to more accurately predict corporate failure.

Enhancing the Economic Growth of Africa: Does Banking Sector Efficiency Matter?

Abstract: Purpose – The purpose of this paper is to examine the relationship between banking sector efficiency and economic growth in Africa. Methodology/approach – The paper used the stochastic frontier approach stating the banking sector cost function as a Fourier flexible to estimate bank efficiency. We then used the Arellano–Bond GMM estimator to investigate the relationship between banking sector efficiency and economic growth. Annual data for banking sector financial statements were used in estimating efficiency scores. Findings – The study found banking sector efficiency in the sample to be 69%. We also found a positive relationship between banking sector efficiency and economic growth, confirming the critical role banks play in the economy. Practical implications – Banking sector efficiency score of 69% implies banks in Africa could save up to 31% of their total cost if they were to operate efficiently. Policy direction should therefore focus on policies and incentives that will improve the efficiency of the banking sector and hence economic growth. The study brings to the fore the importance of the qualitative aspect of the banking sector in allocating financial resources in the real economy. Focus in the real economy should not be only on the size of the banking system but also on the quality with which resources are allocated. Originality/value of paper – This study is among the first dedicated solely to African countries. It does set the pace for future research in the area and also confirms in Africa the Schumpeterian hypothesis that the banking sector is key in allocating resources in the real economy.

Nudge: Improving Decisions about Health, Wealth, and Happiness

Abstract: NUDGE: IMPROVING DECISIONS ABOUT HEALTH, WEALTH, AND HAPPINESS by Richard H. Thaler and Cass R. Sunstein Penguin Books, 2009, 312 pp, ISBN 978-0-14-311526-7This book is best described formally as a general explanation of and advocacy for libertarian paternalism, a term coined by the authors in earlier publications. Informally, it is about how leaders, systems, organizations, and governments can nudge people to do the things the nudgers want and need done for the betterment of the nudgees, or of society. It is paternalism in the sense that "it is legitimate for choice architects to try to influence people's behavior in order to make their lives longer, healthier, and better", (p. 5) It is libertarian in that "people should be free to do what they like - and to opt out of undesirable arrangements if they want to do so", (p. 5) The built-in possibility of opting out or making a different choice preserves freedom of choice even though people's behavior has been influenced by the nature of the presentation of the information or by the structure of the decisionmaking system. I had never heard of libertarian paternalism before reading this book, and I now find it fascinating.Written for a general audience, this book contains mostly social and behavioral science theory and models, but there is considerable discussion of structure and process that has roots in mathematical and quantitative modeling. One of the main applications of this social system is economic choice in investing, selecting and purchasing products and services, systems of taxes, banking (mortgages, borrowing, savings), and retirement systems. Other quantitative social choice systems discussed include environmental effects, health care plans, gambling, and organ donations. Softer issues that are also subject to a nudge-based approach are marriage, education, eating, drinking, smoking, influence, spread of information, and politics. There is something in this book for everyone.The basis for this libertarian paternalism concept is in the social theory called "science of choice", the study of the design and implementation of influence systems on various kinds of people. The terms Econs and Humans, are used to refer to people with either considerable or little rational decision-making talent, respectively. The various libertarian paternalism concepts and systems presented are tested and compared in light of these two types of people. Two foundational issues that this book has in common with another book, Network of Echoes: Imitation, Innovation and Invisible Leaders, that was also reviewed for this issue of the Journal are that 1 ) there are two modes of thinking (or components of the brain) - an automatic (intuitive) process and a reflective (rational) process and 2) the need for conformity and the desire for imitation are powerful forces in human behavior. …

The Human Side of Enterprise.

Abstract: \"What are your assumptions (implicit as well as explicit) about the most effective way to manage people?\" So began Douglas McGregor in this 1960 management classic. It was a seemingly simple question he asked, yet it led to a fundamental revolution in management. Today, with the rise of the global economy, the information revolution, and the growth of knowledge-driven work, McGregor's simple but provocative question continues to resonate-perhaps more powerfully than ever before. Heralded as one of the most important pieces of management literature ever written, a touchstone for scholars and a handbook for practitioners, The Human Side of Enterprise continues to receive the highest accolades nearly half a century after its initial publication. Influencing such major management gurus such as Peter Drucker and Warren Bennis, McGregor's revolutionary Theory Y-which contends that individuals are self-motivated and self-directed-and Theory X-in which employees must be commanded and controlled-has been widely taught in business schools, industrial relations schools, psychology departments, and professional development seminars for over four decades. In this special annotated edition of the worldwide management classic, Joel Cutcher-Gershenfeld, Senior Research Scientist in MIT's Sloan School of Management and Engineering Systems Division, shows us how today's leaders have successfully incorporated McGregor's methods into modern management styles and practices. The added quotes and commentary bring the content right into today's debates and business models. Now more than ever, the timeless wisdom of Douglas McGregor can light the path towards a management style that nurtures leadership capability, creates effective teams, ensures internal alignment, achieves high performance, and cultivates an authentic, value-driven workplace--lessons we all need to learn as we make our way in this brave new world of the 21st century.
