Significant drivers of growth in Africa

We employ bootstrap techniques in a production frontier framework to provide statistical inference for each component in the decomposition of labor productivity growth, which has essentially been ignored in this literature. We show that only two of the four components (efficiency changes and human capital accumulation) have significantly contributed to growth in Africa. Although physical capital accumulation is the largest force, it is not statistically significant on average. Thus, ignoring statistical significance would falsely identify physical capital accumulation as a major driver of growth in Africa when it is not.

A Review of: THE EVALUATION OF RISKY INTERRELATED INVESTMENTS by Frederick S. Hillier

The flood of publications and seminars on activity costing in the last few years suggests that companies suddenly encountered a need for better management accounting information in the 1980s. In fact, management accounting's relevance to most business decision-making deteriorated steadily since the 1950s. However, most companies did not perceive these inadequacies in management accounting until the early 1980s. Current interest in activity management and activity costing reflects the convergence around 1980 of two forces: a long-undetected set of problems in management accounting that seems to originate in the 1950s; and the growth of new competitive pressures in the 1970s that made companies acutely aware of these problems. Although these two forces arose independently, their interaction in the 1970s led to the rise of activity-based management thinking. This paper describes the past, present, and future of activity-based management: past uses of financial accounting information that confounded companies' efforts to plan marketing strategies and to control operations after the 1950s; present ideas for solving these problems with activity-based management concepts such as activity costing; and the likely future direction of activity-based management thought.     

Rational Choice in Strategic Environments: Further Observations

This note clarifies some aspects of Bernheim's (1986) characterization of Nash and correlated equilibria.     

Rationalisierung und Rationierung im Gesundheitswesen aus ethischer Perspektive

Demographic ageing and technological progress leads to rising health care costs. Under the assumption that the solidarity-based financing of the German Statutory Health Insurance System will reach its limits, the authors discuss how and on which level questions about rationing should be answered. From an ethical point of view, rationing should be based on general and consistent rules at the governance level rather than on case by case decisions by healthcare providers. Moreover, transparency is inevitable to maintain the relationship of trust between physicians and patients and to improve the patient’s wellbeing.     

Boredom in Free Time: Relationships with Personality,Affect, and Motivation for Different Gender,Racial and Ethnic Student Groups

The propensity to experience boredom in free time was investigated by exploring relationships with the individual's demographic characteristics, personality, motivational orientation, and affective style assessed through group-administered questionnaires to 999 university students. The self-as-entertainment personality attribute consistently predicted the likelihood that students would be bored, and inverse relationships with extraversion and intrinsic motivational orientation were found for all student groups. Multiple regression analyses revealed that race, ethnicity, and gender were the only significant demographic predictors of the likelihood an individual would be bored in free time. Group similarities and differences in depicting students who were prone to experience boredom in free time are described.     

Same Same But Different: Dialects and Trade

Language is a strong and robust determinant of international trade patterns: Countries sharing a common language trade significantly more with each other than countries using different languages, holding other factors constant. In this article we present the first analysis of the effect of language on trade in an intra‐national context. Analyzing unique data for a single‐language country, Germany, we find that similarities in the local dialect have a significantly positive impact on regional trade. We interpret this finding as evidence for the trade‐promoting effect of culture, because linguistic similarities likely reflect cultural ties across regions, rather than lower costs of communication or similar institutions.
