Neighbourhood effects,preference heterogeneity and immigrant educational attainment

This paper investigates differences between the educational attainment of immigrants, children of immigrants and native-born individuals in Australia by using Australian Youth Survey (AYS) data combined with aggregate Australian Census data. Differences in educational attainment are decomposed into: (i) typical demographic and socio-economic sources common to all ethnic groups; (ii) unobserved region of residence and region of origin effects; and (iii) neighbourhood effects such as degree and ethnic concentration of particular ethnic groups in different neighbourhoods. A theoretical model incorporating these effects is proposed but structural estimation is not possible for lack of appropriate data. Instead, a reduced form methodology is proposed and employed. The empirical results identify positive ethnic neighbourhood effects in high school completion and university enrolment for some immigrant groups in Australia, in particular first and second generation immigrants from Asia. The results indicate that it is not just the size of the ethnic network but the ‘quality’ of the network that is important.     

International cattle ID and traceability: Competitive implications for the US

Global standards for animal identification and traceability are evolving rapidly. Major world animal health, trade, and food safety organizations have formally recognized the importance of, and actively promoted, animal identification and traceability system development. Advanced animal traceability systems have been deployed by major beef exporters and are increasingly being adopted by important beef importing countries. This study summarizes and compares animal identification systems across major export and import countries. Results reveal that the United States lags behind both major export and import countries in development and adoption of cattle identification and tracing systems. As such, the United States has placed itself in a vulnerable position relative to competing export countries with respect to demonstrated animal traceability. This status could adversely affect market access in the future for US beef exports.     

Big brands,big cities: How the population penalty affects common,identity relevant brands in densely populated areas

The population density of a geographical area has a well-known and strong positive effect on sales in the area. Yet, for some brands, there may be factors that affect the strength of this density-sales relationship. The present research shows that for product categories that consumers use to signal their identities (e.g., clothing, restaurants and cars), the strength of this relationship varies with brand commonness. Consumers residing in densely populated areas are motivated to express their distinctiveness by reducing their preference for identity relevant brands that are common, such as large chains and brands owned by many people. Thus, as identity-relevant brands become more common, they suffer from a “population penalty” – a weakening of the positive effect of population density on sales. We show this effect with three experiments and two empirical analyses of automobile and alcohol sales. Our findings extend literature on distinctiveness theory by demonstrating these effects at the community level and provide insights for marketers on accounting and adjusting for this effect.

Healthy lifestyle and safety: An expected net benefit approach to seat belt use

This paper examines the relationship between motorist safety belt use and three lifestyle behaviors affecting health. A healthy lifestyle affects benefits of seat belt use because it indicates a greater value on safety. If individuals are rational in their behavior, we expect consistency across health and safety choices. Using a nationwide survey sample and logit analysis we find lifestyle has expected effects on belt use holding constant individual and vehicle characteristics. Illustrations for two different lifestyles are considered: (1) smoking 1 pack per day, 2 years between dental visits, and no regular exercise and (2) no smoking, 1 year between dental visits and regular exercise. Healtiher lifestyle increases the probability of seat belt use by more than 50% for typical individuals     

Beyond the Return on Advertising: Elasticity of the Return on Advertising as a Diagnostic Metric to Maximize Profit

With increased marketing expenditures, managers need to be equipped with valid and reliable measures capable of showing links between marketing investments and a firm's profitable performance. In this paper we demonstrate that traditional return on advertising (ROA) can be a misleading metric if a firm's goal is profit maximization. Then, we introduce a new diagnostic tool: the elasticity of ROA and show how this metric can help marketing managers to choose more profitable levels of advertising. This new measure has the same virtues as other traditional measures of elasticity and provides real advantages over the conventional metrics.     

The Market Value of Reducing Cancer Risk: Hedonic Housing Prices with Changing Information

In this paper, we use housing price changes occurring after the release of a regulatory agency's environmental risk information to estimate the value people place on cancer risk reduction. Using a large original data set on the repeal sales of houses, matched with detailed data on hazardous waste cancer risk and newspaper publicity, we find that housing prices respond in a rational manner to changes in information about risk. Since the new information indicated that the sites in our sample pose relatively low cancer risk, the informational release led residents to lower their risk beliefs, resulting in an average housing price increase of $56 to $87. This price change implies a statistical value per case of cancer of $4.3 million to $8.3 million, which is similar to the estimates obtained in labor market studies of the value of a statistical life. Newspaper publicity about the local sites increased housing prices, suggesting that residents perceived the news as good.     

Shifting sands? trade unions and productivity at Rover Cars

This article examines the impact of trade unions on productivity at Rover Cars. Intra-organisational variables which influence productivity levels at Rover are also considered. It concludes that the positive approach by both management and unions to collective bargaining in the late 1980s yielded significant gains in performance. This endorses the view of the Harvard School of economists who argue that unionism can be a force for greater economic efficiency.
