OBESITY AND NUTRIENT CONSUMPTION: A RATIONAL ADDICTION?

Recent research shows that the dramatic rise in obesity in the United States is due more to the overconsumption of unhealthy foods than underactivity. This study tests for an addiction to food nutrients as a potential explanation for the apparent excessive consumption. A random coefficients (mixed) logit model is used to test a multivariate rational addiction model. The results reveal a particularly strong addiction to carbohydrates. The implication of this finding is that price-based policies, sin taxes, or produce subsidies that change the expected future costs and benefits of consuming carbohydrate-intensive foods may be effective in controlling excessive nutrient intake.

The effect of phosphate detergent bans on consumer clothing expenditures

Metropolitan sales data from the 1977 Census of Retail Trade were analysed to test whether phosphate detergent bans increased consumer expenditure on clothing: positive effects were found for men's clothing and domestic fabrics (sheets and towels). In areas with medium water hardness the average annual cost in 1977 equalled $11·08 per household. For 1984, the equivalent cost was $14·17 per household. These results are consistent with laboratory studies that show decreased detergency associated with non-phosphate detergents and increased fabric wear associated with carbonate-built detergents, the principle substitute for phosphate detergents. The bans impose the largest cost on hard water areas. In both ban and non-ban areas in 1977 higher laundering costs were associated with higher water hardness. Analysis of 1972 data indicated that water hardness did not affect clothing expenditures significantly when detergents contained large amounts of phosphates.     

Do Central Bank Forecasts Influence Private Agents? Forecasting Performance versus Signals

Focusing on a set of central banks that publish inflation forecasts in real time, this paper aims to establish whether central bank inflation forecasts influence private inflation forecasts. The response is positive in the five countries studied: Sweden, the United Kingdom, Canada, Switzerland, and Japan. Three hypotheses may explain this central bank influence: central bank forecasts are more accurate than private ones, are based on different information sets, and/or convey signals about future policy decisions and policymakers’ preferences and objectives. We provide evidence that the source of these central banks’ influence is not linked to their forecasting performance.     

An investigation into some aspects of the efficiency of low-temperature laundering

The purpose of this research was to investigate the efficiency of laundering at low and recommended water temperatures using a heavy-duty biological detergent and a low-temperature detergent. The effectiveness of the process was measured in terms of the degree of stain/soil removal from laundered garments, and in the removal and transfer of bacteria from infected test pieces. The results indicate that with both detergents a reduction in washing efficiency occurs as the temperature of laundering is decreased, except when the difference between the recommended and low water temperature is small. Evidence was also obtained that shows that reducing wash temperatures decreases the degree of disinfection and increases the cross-infection of articles washed in the same load.     

OUTPUT,OUTCOME, AND QUALITY ADJUSTMENT IN MEASURING HEALTH AND EDUCATION SERVICES

This paper provides an overview of measuring price and volume changes of the output of health and education providers. In the national accounts, outputs should reflect the results of production and these cannot normally be captured by outcome, the state of health or education of the population. However, we show that outcome information is required when it comes to quality adjustment of output measures. The paper clarifies terminology, and discusses output measurement and quality adjustment methods with a focus on health and education services.     

ANOTHER LOOK AT THE RELATIONSHIP BETWEEN INNOVATION PROXIES*

Shortcomings in the treatment of intangible investment in company accounts imply that there is no statistical collection for innovative activity which abides by the logic used for other economic activity data. As a consequence, analysts rely on innovation proxies derived from administrative and survey data. However, it is still unclear exactly how the different proxies are correlated, and whether the choice amongst different proxies matters. In the light of the innovation measurement, this paper takes another look at the relationship between different proxies of firm innovation. The results show that firm‐level correlations between survey‐based indicators and other proxies for innovation are highest for manufacturing firms and for product innovations.     

Credit,reputation, and masculinity in British urban commerce: Edinburgh,c. 1710–70 1

This article draws on cases of public insult from the Edinburgh consistory court to explore constructions of credit and reputation during the eighteenth century. Scotland's unique legal context offers new insights into the honour of men and women, replacing the received view that female honour was almost entirely about sexual honour and complicating our understanding of male honour among the middling sort. In contrast to studies that view the credit of men and women as principally contradictory, this study instead identifies significant points of both overlap and divergence in male and female reputation and discusses honour as a family matter. Unlike in England, levels of defamation litigation in Scotland remained high through the eighteenth century, and both the social composition of defamation litigants and the types of insult they brought to court remained consistent. However, the forms and settings of disputes over honour changed, reflecting the interiorization of conflict as the eighteenth century progressed.     

Effects Of Obsolescence On Tax Depreciation Practice

To paraphrase an old saying: Everybody complains about the way obsolescence is handled in tax depreciation practice, but nobody has as yet found a solution that satisfies both the taxpayer and the tax collector. It is obvious that this problem is much too big to treat in detail in this short article, but an attempt will be made to discuss several aspects of the problem which the writer believes either have not been fully understood by most persons, or else have not been explained sufficiently by those who advocate certain procedures. In order to develop the subject adequately, it will be necessary to investigate certain matters not directly concerned with tax practice
