Ubuntu: A transformative leadership philosophy

Leadership is about knowledge, skills, and abilities for transformation. It is also increasingly about worldviews or visions of life—beliefs, values, and principles. But worldviews are also ways of life, for beliefs direct us, values guide us, and principles motivate us to certain kinds of action and behavior. How, then, do worldviews have an impact on leadership for transformation? If worldviews are glasses or filters by which we view the world, mental models of the bigger picture, frameworks by which we make sense of the world, and narratives by which we orient our lives, then how do they influence human thoughts, ideas, and behaviors when it comes to transformative leadership? This was the subject matter of an International Leadership Association Conference panel discussion held in November 2009 in Prague, entitled Leadership for Transformation: The Impact of Worldviews. It is also the subject matter of this issue's symposium, in which we bring you the four papers and the response presented at the conference. Members of the panel were characterized by gender, disciplinary, religious, and global diversity. Nathan Harter, organizational leadership professor at Purdue University in the United States, begins the discussion with some preliminary remarks about worldviews. Ali Mohammed Mir, medical doctor and director of programs of Population Council, Pakistan, speaks of leadership from an Islamic perspective. Michael Jones, accomplished composer, pianist, and leadership educator, writer, and speaker from Orillia, Canada, reflects on how a “marriage of mythos and logos” can transform leadership today. Lisa Ncube, originally from Zimbabwe and currently assistant professor of organizational leadership at Purdue University, speaks about Ubuntu as an alternative leadership philosophy emerging from Africa. John Valk, associate professor of worldview studies at Renaissance College, University of New Brunswick, Canada, speaks of leadership for transformation from a Christian worldview perspective. Jonathan Reams, associate professor in the Department of Education at the Norwegian University of Science and Technology in Trondheim, responds to all of the papers and opens a venue for further discussion. We hope that you will find this symposium engaging. We hope it will give food for thought and that it might stimulate further thinking regarding the role worldviews play in leadership for transformation.     

The Real Exchange Rate and Growth in Emerging Markets: The Case of Zimbabwe

Zimbabwe has been facing growth and external competitiveness challenges, as shown by declining shares in global exports, high current account deficits, external debt and a widening productivity gap with South Africa. Estimates of the real equilibrium exchange rate reveal periods of sizeable misalignment, both prior to 2008 and under the current multicurrency regime. Misalignment has an asymmetric impact on growth. While overvaluation hampers growth, we have not found robust evidence that undervaluation would raise it. Replacing the multicurrency regime anchored in the US dollar by the South African rand would help reduce overvaluation and stimulate exports and growth. Under any currency regime, Zimbabwe needs to implement sound macroeconomic policies and an environment conducive to investment.     

The Statistical Properties of the Black–Scholes Option Price

This paper investigates the statistical properties of the Black–Scholes option price, considered as a random variable. The option is conditioned on the current price and/or the estimated volatility of the underlying security. In both cases, some exact results for the distribution functions of the true option price and the predicted option price are derived. Extensions to puts and American contracts are considered. Numerical results are presented for option prices based on parameters appropriate for the FTSE 100 Index.     

Competition and Efficiency in the Banking Sector in South Africa

Abstract: We analyse the evolution of competition and efficiency of the banking sector in South Africa using firm‐level data for the period 1999–2008. We adopt a three‐step estimation approach. First, we measure efficiency using the data envelopment analysis (DEA) methodology. Second, we use the Panzar–Rosse approach to derive the H‐statistic for competitive conditions in banking. In the third stage, we take into account the role of managerial ability in competition by re‐estimating the Panzar–Rosse model, with the DEA efficiency scores as an explanatory variable. Overall, the results show that although average efficiency was trending upwards over the period, the number of efficient banks was falling. Also, it is found that for the period 1999–2008, the structure of the South African banking industry was characterized by monopolistic competition. This result may reflect domination by five large banks, which together account for over 85 per cent of total banking assets.     

Political Economy of Service Delivery: Monitoring Versus Contestation

Many communities suffer limited public goods provision due to civil servants (doctors, teachers, etc.) supplementing their low income with moonlighting activities. Monitors of civil servants commonly also earn low salaries from monitoring and may prefer political contestation for power and prestige. We determine an internal equilibrium for how monitors strike a balance between monitoring and political contestation, and a corner solution where an unresourceful monitor does not monitor. Multiple characteristics, including the intensity of political contestation, are accounted for. Survey data from Tanzania and Senegal are used to show the significance of poor service delivery within education and healthcare services.
