Geography,demography, and economic growth in Africa

This paper presents the effects of climate, topography, and natural ecology on public health, nutrition, demographics, technological diffusion, international trade and other determinants of economic development in Africa. The goal of this paper is to emphasize the need for intensified research on the issues at the intersection of ecology and human society. Geography was given emphasis because of three reasons: the minimal gain from another recitation of the damage caused by statism, protectionism and corruption to African economic performance; negligence of the role of natural forces in shaping economic performance; and tailoring of policies to geographical realities. The paper also discusses the general problems of tropical development and the focus of Africa's problems in worldwide tropical perspectives; demographic trends in Africa; use of standard cross-country growth equations with demographic and geographic variables, to account for the relative roles of geography; and the future growth strategies and the need for urban-based export growth in manufacturing and services. Lastly, the authors provide a summary of conclusions and discuss the agenda for future research.     

Emotion As Well As Reason: Getting Students Beyond "Interpersonal Accountability"

The paper notes the recent spread of business ethics courses in American higher education, observing that teachers trained in economics have not readily incorporated ethical notions or theory into regular courses, such as finance, management, accounting, and marketing. The presumed ethically neutral, value-free approach of economists, who dominate business courses, is increasingly inadequate to meet the needs of business managers – or of business students. Technological and political changes, creating an interdependent environment within which managers operate, have eroded older ethics based on tradition and common backgrounds. They have also raised ethical issues of new orders of complexity. With corporate business managers finding ethical concerns more pressing matters than do many teachers, the paper offers some tentative answers to three questions about how to interest business students in ethical issues: What Approach to Business Ethics Gets student's Attention? What Is the Value of Simulations and Games? What Can Be Said About the Business System And Its Values? The answer to the first question is simulations and games. Case method analysis is serviceable, engaging students' intellect, but all too often without emotional involvement or self-revelation. Experiential learning through class-room games accomplish both engagement and involvement in ways that are exceedingly helpful to business students, who have had "less occasion for critical reflection on self and world than have others of their age." The answer to the second question is: They engage the whole student, stimulating the player to examine the source of her ethical strengths and the reasons for ethical lapses. Generating emotional involvement the games leverage and enhance reasoning, allowing students to learn more about their own values and question their own behavior. The answer to the third question is: A socially justifiable (community-legitimated) competitive market system requires of its managerial participants an emotionally informed response – as well as a rational analysis and use of business techniques. Business operates with enhanced effectiveness efficiency at appropriate levels of such virtues as loyalty, trustworthiness and cooperativeness; they ensure externality benefits as well as promote justice for its own ultimate social justification.     

A new mandate for human resources

Should we do away with HR? In recent years, a number of people who study and write about business--along with many who run businesses--have been debating that question. The debate arises out of serious and widespread doubts about HR's contribution to organizational performance. Dave Ulrich acknowledges that HR, as it is configured today in many companies, is indeed ineffective, incompetent, and costly. But he contends that it has never been more necessary. The solution, he believes, is to create an entirely new role for the field that focuses it not on traditional HR activities, such as staffing and compensation, but on business results that enrich the company's value to customers, investors, and employees. Ulrich elaborates on four broad tasks for HR that would allow it to help deliver organizational excellence. First, HR should become a partner in strategy execution. Second, it should become an expert in the way work is organized and executed. Third, it should become a champion for employees. And fourth, it should become an agent of continual change. Fulfilling this agenda would mean that every one of HR's activities would in some concrete way help a company better serve its customers or otherwise increase shareholder value. Can HR transform itself on its own? Certainly not--in fact, the primary responsibility for transforming the role of HR, Ulrich says, belongs to the CEO and to every line manager who works with the HR staff. Competitive success is a function of organizational excellence, and senior managers must hold HR accountable for delivering it.     

Debt, Leases, Taxes, and the Endogeneity of Corporate Tax Status

We provide evidence that corporate tax status is endogenous to financing decisions, which induces a spurious relation between measures of financial policy and many commonly used tax proxies. Using a forward-looking estimate of before-financing corporate marginal tax rates, we document a negative relation between operating leases and tax rates, and a positive relation between debt levels and tax rates. This is the first unambiguous evidence supporting the hypothesis that low tax rate firms lease more, and have lower debt levels, than high tax rate firms.     

Real Rates, Expected Inflation, and Inflation Risk Premia

This paper studies the term structure of real rates, expected inflation, and inflation risk premia. The analysis is based on new estimates of the real term structure derived from the prices of index-linked and nominal debt in the U.K. I find strong evidence to reject both the Fisher Hypothesis and versions of the Expectations Hypothesis for real rates. The estimates also imply the presence of time-varying inflation risk premia throughout the term structure.
