A generalized economic-uneconomic boundary for short run product and cost curves

Conclusions It has been found that for any production function homogeneous of degreem, the tangency point between theLRAPL curve and theSRAPL curve will provide a demarcation between those points that are economic, and hence relevant, and those that are uneconomic and hence irrelevant. As a special case, for a linear homogeneous function, the intersection ofSRAPL withSRMPL also coincides with this boundary.     

Effects of Child Health on Sources of Public Support

We estimate the effects of having a child in poor health on the mother's receipt of Temporary Assistance for Needy Families (TANF), Supplemental Security Income (SSI), and public support in the form of food (Special Supplemental Nutrition Program for Women, Infants, and Children [WIC] or food stamps), health insurance (Medicaid), and housing. We find that mothers with unhealthy children are between 2 and 8 percentage points (8-33%) more likely to rely on TANF than those with healthy children. There are stronger effects for mothers with older children than for those having first births. Mothers of children in poor health are also more likely than those with healthy children to receive SSI, Medicaid, and housing assistance but not WIC or food stamps. Given the restrictive new welfare environment, mothers who rely on TANF to cope with the burden of caring for unhealthy infants may soon encounter difficulties making ends meet and have insufficient resources to invest in their children's health.     

Consumer knowledge of the world wide web: Conceptualization and measurement

User‐directed technologies such as the Web are becoming more prevalent. To understand the usage of these technologies the characteristics of users need to be studied. The focus here is on one user characteristic: consumer knowledge content. Based on qualitative and quantitative analyses, four scales are developed to measure common declarative, common procedural, specialized declarative, and specialized procedural knowledge content of the Web. In addition, an illustration is provided to show how these scales might be used for segmenting consumers. The procedures used may be of value in a wide range of studies where the focus is on investigating users of user‐directed electronic technologies. © 2004 Wiley Periodicals, Inc.     

Ricardian Consumers With Non-Keynesian (And Possibly Ricardian) Propensities

Barsky, Mankiw and Zeldes (1986) have argued that uncertainty about future income can generate strong ‘Keynesian’ responses to tax changes by consumers who have far‐sighted ‘Ricardian’ preferences. The paper argues that this conclusion relies on an inappropriate treatment of future tax policies. Using a more appropriate framework generates behaviour which may instead be approximately Ricardian, and which, if it deviates from the Ricardian benchmark, usually does so in an anti‐Keynesian direction. If Keynesian behaviour is observed, therefore, it requires a different explanation.     

Social Partnership Agreements in Britain: Labor Cooperation and Compliance

This article reviews evidence on the outcomes of British social partnership agreements using matched comparisons. It concludes that in industries marked by employment decline, partnership firms often have shed jobs at a faster rate than nonpartnership firms. However, in expanding sectors, partnership firms have created jobs at a faster rate than nonpartnership rivals. There is no discernible impact of partnership on either wage settlements or union density. It is argued that we need evidence on information sharing, trust, and power and suggested that partnership agreements are unlikely to contribute significantly to union revitalization.     

A fisherian analysis of individual retirement accounts

Conclusions This paper has employed a Fisherian analysis of intertemporal choice to evaluate the use of IRA's. The analysis shows that with perfect capital markets assumptions, the presence of IRA's will generate no other effect on savings than would a simple tax rabate. Further, it shows that if the tax revenue loss due to IRA's is not accompanied by an expenditure reduction, but is financed with taxes or borrowing, rational households will still employ IRA's, but their effect on intertemporal choice will be nil. The analysis also shows that IRA's do act as a savings incentive to the extent that there are market imperfections, specifically to the degree that transactions costs are important. However, empirical evidence from the literature does not lend firm support to this possibility. The conclusion is that a market imperfection is not a firm basis on which to construct savings incentives. Finally, one can note that the same analysis applies to any tax-based savings incentive that is designed to operate by lowering the tax on interest income. The reason for this finding is that the provision of tax sheltered interest income, along with the deductibility of interest on borrowing, creates general tax arbitrage opportunities for households and that tax arbitrage opportunities do not, in general, generate greater savings in an intertemporal choice model. It follows that significant restriction or elimination of the deductibility of interest on borrowing is a prerequisite for IRA's and other tax based savings incentives to produce their intended effect.     

Multidimensional accounting and distributed databases: Their implications for organizations and society

The motivation behind multidimensional accounting is elaborated and extended to an accounting system built upon a database. This system may serve as the predecessor to a national system of distributed databases that integrates micro-accounting and macro-accounting systems. Two implications for organizations and society are examined: first, the need to standardize information requirements, and second, the need to protect privacy. Recent advances in the application and development of cryptosystems are examined. These advances enhance security and the protection of privacy within a database in a simple and inexpensive fashion.     

The New Barbarians: The Continuing Relevance of Henry George*

Abstract . The world's peoples are demanding: who should be the Lords of the Land or—should anyone be? By what right does anyone acquire the privilege of monopolizing that which should be the heritage of all? A century ago Henry George saw the nature of this question, the land question, outlined the solution and foresaw the consequences if we failed to address it. The rioting in the slums, the looting and other crime in the cities and rural areas, the tension of our time, the rising fears, paranoia and greed bear testimony to the legacy George foresaw. Against monopoly and privilege, George raised the banner of Justice and Liberty, achievable only by taxing the land and untaxing labor and its products. The failure to act upon the land question is at the bottom of the threat of a new barbarism. But the Intellectual Revolution fostered by the new computer technology promises to undermine myths that have enslaved the human mind.
