Consumption in Contemporary Capitalism: The Backward Art of Living

Western economies have undergone a significant transformation over the last half a century as they have moved away from a commitment to full employment, going from activist fiscal policy to its abandonment with the adoption of budgetary austerity. This is not because of any technical or physical incapacity to achieve full employment. Analyzing the broad macroeconomic experience of Canada and the United States in the post-WWII era, the article finds that this growing unemployment has essentially resulted from a deliberate policy choice not to stimulate sufficiently demand via fiscal measures. Learning from the experience of the Great Depression, Michal Kalecki had offered an explanation for this type of policy response in favor of rising long-term unemployment. This article recognizes the relevance and appropriateness of Kalecki's analysis and seeks to determine whether the Minskian institutional proposal for achieving effective full employment (via government as the employer of last resort) would withstand an original Kaleckian critique.

A preliminary comparative analysis of 3D body scanner,manually taken girth body measurements and size chart measurements

In an attempt to provide a technological solution to the influx of cheap imports in South Africa and bridging the technology divide between Africa and the rest of the world, the Council for Scientific and Industrial Research procured a three‐dimensional body scanner from the Textile and Clothing Technology Corporation, in the US. The pilot study was aimed at introducing the technology to the South African consumers, and to compare the scanned data with the manually taken measurements. A convenience sample of 56 females in South Africa was interviewed using a structured questionnaire. Interviews were used to capture views on acceptance of the technology, prior to being scanned. Scanning garments made from a stretchy fabric were designed and sewn in four sizes of small, medium, large and extra large. A covariance, one sample t‐test and paired t‐ tests were used for data analyses. Almost all respondents felt comfortable with the designed scanning garments and the scanning process. The scanner measurements were generally more numerical in value than the manual measurements for a body part as expected, although the disparity was on the higher side than expected. The discernible difference between means of scanned data and standard values in the currently used sizing charts highlighted the long overdue need to update the sizing charts using a national anthropometric database generated locally.
