Did Hayek have a monetary theory of business cycles?

Joseph Schumpeter, a careful reader of Hayek, categorized Hayek??s theory of economic cycles as non-monetary. Almost every other source, including Hayek himself, categorized the theory as monetary. The issue turns on the concept of causality being used. The question of what causality concept to apply to complex phenomena has substantive implications for economic theory. A simple concept of causality, appropriate to the study of some physical phenomena, will mislead when applied to complex phenomena. We provide examples of errors in analysis that follow from the wrong choice of a causal paradigm.     

Profiling emerging contractors for effective transformation in the South African construction sector

South Africa's construction industry is transforming. Its economy requires a wider base of contracting entities. Much of this growth is expected to be delivered by ‘emerging’ contractors. Yet these companies face significant obstacles. Targeted interventions that foster companies need a better picture of these firms and their core members. A survey of the civil engineering sector, targeting emerging contractors, showed that the owners of these companies lack training and experience, and that there are gender-related differences. Classifications according to company turnover, contract sizes or employee numbers alone do not reflect circumstances. Combining these data with the core members' backgrounds gives a clearer picture. Most companies hover between the ‘Existence’ and ‘Survival’ stages of business development. Development initiatives that assume companies require knowledge must accommodate large cognitive distances between sender and receiver. Initiatives thus need to focus on the owners, considering the status and background of their companies.     

Financial Education and Counseling—Still Holding Promise

This article reviews the evaluation literature on financial education and counseling for adults in order to synthesize implications for research and practice. Most evaluations report positive impacts, but the findings are often small when compared with valid comparison groups. Many evaluations use self-reported measures, measure outcomes over short time periods and cannot rule out selection bias due to nonrandomized designs, all of which may bias results. Although future research and practice in this field hold promise, more attention to theory-based evaluations and further investment in randomized field experiments may be fruitful.     

Effects of ideal image congruence and organizational commitment on employee intention to leave

The purpose of this study was to investigate the relationships among employee self-image/store image congruence, employee–store commitment, and employee intention to leave within the context of retail stores. Data were collected using a survey method. Usable questionnaires were completed by 276 retail store employees. Path analysis was used to test the hypotheses. Results revealed employee self-image/store image congruence was positively related to store image attractiveness. In turn, store image attractiveness was positively related to employee–store commitment both directly and indirectly through intrinsic job satisfaction. Lastly, both intrinsic job satisfaction and employee–store commitment were negatively related to employees’ intention to leave.     

Interrelations between the dynamics of oil prices and demand: Contemporary characteristics

The article shows that the unprecedented rise in oil prices was in recent years accompanied by an increase in oil consumption. The author considers the growth that was seen in the magnitude of oil sales despite multiple increases in price to be, along with the buying up of oil as a high liquidity asset, a phenomenon that indicates an approaching crisis and allows us to create new approaches to its forecasting.     

Supply Chain Management Competency and Firm Financial Success

Supply chain management (SCM) plays a major role in creating (or destroying) shareholder value by influencing the three major drivers of firm financial performance: revenue, operating costs, and working capital. Yet, the relationship between SCM competency and firm financial performance is not well‐established. Drawing on the resource‐based view of the firm, this study assesses this relationship using Delphi‐style opinion data from AMR Research’s Supply Chain Top 25 rankings to assess SCM competency and Altman’s (1968) Z‐score statistic as the measure of financial success. The study findings show that firms recognized by industry experts for SCM competency have significantly higher Z‐scores than their close competitors and industry averages.     

May the course of the tuberculosis-mortality chiefly be explained by the movements of the infection-curve (tuberculin-curve)?

Abstract

Let us suppose that we have a population which is kept constant by the birth of 10,000 children annually, and that this has been the case for a number of years.
