Young people in the UK consume far above the maximum recommended levels of added sugar. It is likely that neither they nor their parents fully take account of the future health, social and economic costs of this high sugar consumption. This provides a rationale for policy intervention. The majority of young people's added sugar consumption occurs in the home, where purchases are typically made by parents. This means that understanding the purchase decisions of adults is important for policy design, even if the policies aim to reduce the consumption of young people. We discuss the merits of popular policies, including taxes, advertising restrictions and restrictions on the availability of specific foods, and we identify promising avenues for future research.  相似文献

We derive the sampling variances of generalized entropy and Atkinson indices when estimated from complex survey data, and show how they can be calculated straightforwardly using widely available software. We also show that, when the same approach is used to derive variance formulae for the independent and identically distributed case, it leads to estimators that are simpler than those proposed before. Both cases are illustrated with a comparison of income inequality in Britain and Germany.  相似文献

Many virtual project teams perform better when leadership is shared (rather than centralized with the formal team leader); however, team leaders are often neither prepared to identify shared leadership potential nor to actually share leadership responsibility. Based on a study of 96 globally dispersed software development teams we show that team leaders tend to underestimate the team members’ capacity to lead themselves. As a consequence, these leaders monopolize decision‐making authority and provide insufficient levels of autonomy for team members to tackle their tasks. Preventing the team members from unfolding their true potential, these leaders unconsciously jeopardize virtual team performance. Paradoxically, it is thus team leaders themselves hindering leadership effectiveness in virtual teams.  相似文献

In 1988 public sector steelmaking in Britain was extinguished by the sale of all shares in British Steel plc. Given the politicised history of steel, the ease with which the company floated is surprising. This article suggests explanations which lie in the character of the principal industrial actors and the main political parties.  相似文献

Abstract This paper provides evidence on the impact of company training, of post-compulsory education and of the UK Youth Training Scheme in the late 1980's on the earnings of 21-year-old employees in England and Wales. Earnings equations are estimated for each of seven groups of employees who have followed alternative routes from compulsory education into employment, allowing for selectivity into these routes. There are several findings, including: both high parental social class and better school qualifications help to channel people into higher status routes, while high local unemployment has the opposite effect; participation in company training in long spells substantially raises wages but short spells do not; YTS participation fails to raise, and possibly substantially lowers, wages even three years after graduation compared to those who left school at 16 and went to work and received no training; there is weak evidence that, even for those that do not enter higher education, it is better to stay on at school after 16 than go into YTS.  相似文献

This paper uses a macroeconomic model of investment behaviour to identify cyclical activity in UK investment. Various cycles are detected and their lengths are estimated. As a new contribution to the business cycle literature, we estimate the gestation lags inherent in investment projects (arising from capital adjustment, buildings construction etc.) that are considered central to the creation of fluctuations in economic activity. We find multiple and statistically significant cycles in our investment series, including a 3.1‐year Kitchin cycle, a 9.6‐year Juglar cycle and a 22.2‐year Kuznets swing, driven by gestation lags of 1.1 years, 2.4 years and 12 years respectively.  相似文献
