Funding structure and technical efficiency: A data envelopment analysis (DEA) approach for banks in Ghana

Abstract: The purpose of this paper is to examine the effect of funding structure on technical efficiency of banks in Ghana, between 2011 and 2016.,Employing the random-effect and the truncated panel data of 25 banks, the results present new evidence.,The findings reveal that Ghanaian banks are less technically efficient, as the average efficiency scores generated is below the threshold of 1. Furthermore, the results show that banks in Ghana finance their operations mainly with deposit source of funding. The results reveal a significantly positive relationship between funding structure and technical efficiency. However, internally generated source of funds was negatively linked with technical efficiency. This is not surprising because banks that rely on external funds attract higher costs than internally generated funds, and this puts pressure on managers to perform. The results are relevant to emerging economies when the authors use additional macroeconomic factors.,Thus, a proportionally larger deposit base funding would typically lead to an overall increase in technical efficiency of banks in Ghana. Shareholders should put pressure on managers to plough back earnings in order to increase the use of internally generated funds, thus, increasing technical efficiency. Banks that are inefficient should make some adjustments to their weights of inputs and/or outputs combinations by following their benchmark banks (efficient banks) to improve their efficiency.,The results of this study have important implications for regulators, investors and policy makers, particularly an emerging economy. The implication of the study to investors is that investors should be able to identify an appropriate source of funds that can be used efficiently to maximize their wealth in emerging markets. It is important for regulators and managers of banks to improve technical efficiency by considering the role that macroeconomic and monetary environment play when identifying and using various sources of funds as a strategy to improve bank efficiency.,Consequently, future research should investigate the impact of funding structure on technical efficiency for other regions and considering their interactions with institutional quality, macroeconomic factors and financial stability.,To the best of the authors’ knowledge, the study is the first to fulfill an urgent need to explore a robust approach of measuring technical efficiency and funding structure within the context of banks over six-year period, prompting insightful avenues to the survival, growth and performance of financiers in emerging economy.

Risk and performance of non-bank financial institutions

Abstract: This study examines the risk levels of Non-Bank Financial Institutions (NBFIs) and their effect on performance. A panel data analysis of 42 NBFIs over the period of 2006-2010 is used for the study. The results show that NBFIs have been safe as far as bankruptcy is concerned, over the period under study. The risk index used as a measure of overall risk levels show a high mean risk level suggesting that the risk of insolvency of NBFIs in Ghana has been low. The results of the study also establish that lower risk levels lead to an increase in performance of NBFIs. It is further shown that the size of NBFIs has a positive relationship with performance. The results also show that further increases in size of NBFIs measured as the squared of size has a positive impact on performance.

Executive Compensation, Ownership Structure and Loan Quality of Banks in Ghana

Abstract: This paper analyses the effects of executive compensation and ownership structure on loan quality of banks. The study uses a panel data on 26 Ghanaian banks over the period, 2003–2011. Using a dynamic panel model, estimations are made using the Generalized Method of Moments. The results show that management is efficient when director shareholding is very prominent in banks. Institutional ownership and public listing of banks also have a significantly negative relationship with non-performing loans, while lag of non-performing loans, equity ratio, exchange rate depreciation and increases in net interest margins are seen to have a negative effect on loan quality. Executive compensation had no significant effect on loan monitoring.

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.
