Realization and accumulation in a Marxian model of the circuit of capital

A mathematical model of Marx's circuit of capital is presented, whose elements, the composition of capital, the rate of surplus value, the rate of capitalization of surplus value, and production, sales and financial time lags, are measurable from the accounts of capitalist firms. The model is solved for exponential paths. A solution with a positive rate of accumulation generally exists. On paths with positive rates of accumulation and positive time lags in the recommital of realized value to production an expansion of credit is required to permit the sale of commodities. A model of demand pull inflation is incorporated in the framework.     

Consumers' surplus and the demand for cigarettes

This paper examines the demand for cigarettes in South Africa over a 20-year period from 1970 to 1989. Consumption per capita was found to be significantly determined by price and disposable income per capita; but not by advertising. Price and income elasticities and consumers' surplus were computed from the demand model. The question was raised as to whether or not consumers' surplus should be regarded as having been inferred from a health-hazard-discounted demand schedule. The answer depends on the degree to which smoking decisions are taken with full information or, conversely, are influenced by habit. Given the latter assumption, the consumers' surplus measured for cigarette consumption is nevertheless substantially higher than the estimated health costs of smoking as computed by the Medical Research Council.     

Teamwork,Skill Development and Employee Welfare

There has been a sharp divergence in the literature about the benefits of teamwork. Some have claimed that it is solely in the interests of management, others that it is beneficial for employees and yet others that it makes little difference to either productivity or well‐being. This article draws upon the British Skills Survey Series. It shows that while teamwork did expand between the early 1990s and 2006, this was due primarily to the growth of the type of teamwork that allowed employees little in the way of decision‐making power. Indeed, there was a decrease in the prevalence of self‐directive teamwork. At the same time, our evidence shows that the benefits of teamwork, in terms of both enhancing work motivation and employee welfare, are confined to self‐directive teams, while non‐self‐directive teams suppress the use of personal initiative and discretion at work.     

Environmental evaluation of agri-environment schemes using participatory approaches: Experiences of testing the Agri-Environmental Footprint Index

The Agri-Environment Footprint Index (AFI) has been developed as a generic methodology to assess changes in the overall environmental impacts from agriculture at the farm level and to assist in the evaluation of European agri-environmental schemes (AES). The methodology is based on multi-criteria analysis (MCA) and involves stakeholder participation to provide a locally customised evaluation based on weighted environmental indicators. The methodology was subjected to a feasibility assessment in a series of case studies across the EU. The AFI approach was able to measure significant differences in environmental status between farms that participated in an AES and non-participants. Wider environmental concerns, beyond the scheme objectives, were also considered in some case studies and the benefits for identification of unintentional (and often beneficial) impacts of AESs are presented. The participatory approach to AES evaluation proved efficient in different environments and administrative contexts. The approach proved to be appropriate for environmental evaluation of complex agri-environment systems and can complement any evaluation conducted under the Common Monitoring and Evaluation Framework. The applicability of the AFI in routine monitoring of AES impacts and in providing feedback to improve policy design is discussed.     

Using Segmentation and Prototyping in Engaging Politically-Salient Climate-Change Household Segments

Targeting messages to the different segments of a population is necessary to achieve support for policy addressing climate change. Finer segmentation and archetypal prototyping may be advantageous to provide an in-depth understanding of the most politically-salient segments. The research, conducted in Australia, used quantitative analysis to identify subsegments and prototypical respondents, followed by Jungian-style in-depth interviews to reveal the responses of segment representatives to different marketing stimuli. The results suggest that there are challenges in achieving majority support for action against climate change, but there are archetypal words and images that may garner action.
