The effects of soft drink taxes on child and adolescent consumption and weight outcomes

Childhood and adolescent obesity is associated with serious adverse lifetime health consequences and its prevalence has increased rapidly. Soft drink consumption has also expanded rapidly, so much so that soft drinks are currently the largest single contributors to energy intake. In this paper, we investigate the potential for soft drink taxes to combat rising levels of child and adolescent obesity through a reduction in consumption. Our results, based on state soft drink sales and excise tax information between 1989 and 2006 and the National Health Examination and Nutrition Survey, suggest that soft drink taxation, as currently practiced in the United States, leads to a moderate reduction in soft drink consumption by children and adolescents. However, we show that this reduction in soda consumption is completely offset by increases in consumption of other high-calorie drinks.     

International environmental policy and poverty alleviation

We investigate how alternative national and international policies and circumstances impact the Clean Development Mechanism’s (CDM) contribution to sustainable development and the pursuit of poverty eradication goals in developing countries. In particular, we focus on the importance of technology-specific versus technology-neutral environmental regulations in the project host regions. We also consider alternative CDM benefit-sharing arrangements between the host and client regions. An analytical impure-public-good model is developed which considers CDM projects as a conditional transfer exerting price and income effects. These, in turn, induce changes in the use of environmental technologies, and with it global and local environmental protection levels. Aided by model simulations using empirical data for China and the European Union, we seek to assess conditions in which CDM transfers are more favourable towards improved environmental protection and welfare in developing regions.     

Subcontracting,Posted Migrants and Labour Market Segmentation in Finland

Using evidence from the shipbuilding and construction industries in Finland, this article shows how trade union responses to the introduction of migrant workers can be conditioned by product markets. Growing numbers of ‘posted workers’, or intra‐European Union work migrants employed via transnational subcontractors, are segmenting the labour market, by competing with domestically domiciled workers whose employment is more tightly regulated. In Finland, the construction worker's union has had a far more assertive and successful approach to enforcing wage norms than the union in shipbuilding. This appears to be related to the greater exposure of shipbuilding to international product market competition.     

Overlooked issues in the conceptualization and measurement of counterproductive work behavior

The current paper addresses three important yet generally overlooked issues regarding the conceptualization and measurement of counterproductive work behaviors (CWBs). First, we argue that the field would benefit from the adoption of situation-specific CWB measures that are tailored to the organization or occupation being studied. Such an approach would ensure that CWB measures include sample-relevant behaviors and exclude irrelevant behaviors. Second, we discuss several potential sub-dimensions of CWBs that should be examined in future research. These sub-dimensions include: 1) legal vs. illegal activities, 2) hostile vs. instrumental aggression, and 3) task-related vs. non-task-related counterproductive behaviors. Finally, we consider the relevance of the bandwidth-fidelity principle to the measurement of CWBs.     

Labour,leisure, poverty and protest: the 1968 Poor People’s Campaign as a case study

Social movements exist in a liminal space between labour and leisure. Movements require an inordinate amount of work – mobilising communities, studying policy issues, raising funds, organising events and participating in direct action – but protesting can also be fun. Demonstrations engender community through singing, shouting, marching and confronting authority figures. Activists often pass up typical leisure activities and take time off of work to protest. This article examines the 1968 Poor People’s Campaign (PPC) to understand how people engage in both labour and leisure when participating in social movements. During the summer of 1968, a racially, geographically and politically diverse coalition of poor people caravanned to Washington, DC, and built a temporary city where they lived in wooden A‐frame huts for over six weeks in an attempt to expose poverty. Volunteers provided participants with social services and basic necessities they lacked at home, while participants conducted daily protests at nearby government agencies, demanding assistance for the basic needs of housing, food and jobs. While participants suffered under gruelling conditions – living in the summer heat and muddy conditions due to torrential rains – many have recounted how pleasurable the experience was. Most participants had never travelled beyond their home state, and the PPC provided participants with a free trip to the nation’s capital, three square meals a day, a chance to meet new people, and the opportunity to unite with other poor people and demand justice.     

Niche products, generic products, and consumer search

We endogenize product design in a model of sequential search with random firm-consumer match value à la Wolinsky (Quart J Econ 96:493–511, 1986) and Anderson and Renault (RAND J Econ 30:719–735, 1999). We focus on a product design choice by which a firm can control the dispersion of consumer valuations for its product; we interpret low-dispersion products as “generic” and high-dispersion products as “nichy.” Equilibrium product design depends on a feedback loop: when reservation utility is high (low), the marginal customer’s match improves (worsens) with more nichy products, encouraging high (low) differentiation by firms. In turn, when firms offer more nichy products, this induces more intense search; depending on search costs, this could raise or lower consumers’ reservation utility. Remarkably, when the match distribution satisfies a hazard rate condition, firm and consumer interests align: equilibrium product design always adjusts to the level that maximizes utility. When this condition is not met, either multiple equilibria (one nichy, the other generic) or one asymmetric equilibrium (generic and nichy firms coexist) can arise; we argue that the former is more likely for common specifications of consumer preferences.     

Forecasting annual water demands dominated by seasonal variations: the case of water demands in Mecca

Water usage in Mecca is dominated by trends and cyclical variations in the number of foreign pilgrims visiting for the annual Hajj Pilgrimage. Time series regressions show that the mean temperature in Mecca at the time of the Hajj affects the number of pilgrims, inducing a long-term cyclical pattern for this variable and therefore water usage. The cointegrating relation between water usage, number of external pilgrims and temperature produces long-run forecasts of Mecca water demand.     

Grouped coefficients to reduce bias in heterogeneous dynamic panel models with small T

We propose the grouped coefficients estimator to reduce bias in dynamic panels with small T that have a multilevel structure to the coefficient and factor loading heterogeneity. If groups are chosen such that the within-group heterogeneity is small, then the grouped coefficients estimator can lead to substantial bias reduction compared to pooled GMM dynamic panel estimators. We also propose using a Wald test that can be used to assess whether pooled estimators suffer from heterogeneity bias. We illustrate the usefulness of grouped coefficients with an application to labour demand in which the coefficients are grouped by sub-sector. Our results suggest that the standard pooled estimates are substantially biased.     

Functioning, Capability and Freedom: A Framework for Understanding Workplace Disabilities

Work-related disability issues have been central in many of the U.S. public policy debates since the late 1970s and early 1980s. Although there is a robust business, legal, and public policy literature dealing with such issues philosophical analyses are not common. Accordingly, the paper examines, from a broadly philosophical perspective, some of the issues associated with restricted workplace employment opportunities due to the presence of one or more real or perceived disabilities. Following a review of the concept of disability, the paper examines disabilities and impairments using the concepts of functionings and capabilities developed by Amartya Sen and Martha Nussbaum. The paper then connects the capabilities approach to disabilities with the concepts of negative and positive freedom developed by Isaiah Berlin. The paper concludes by suggesting how to address employment and workplace discriminations of disabled people.     

Worldviews and leadership: Thinking and acting the bigger pictures

Leadership is about ideas and actions. Put simply, it is about implementing new ideas into creative actions to achieve desired results. Doing so, however, is far from simple. We know leadership requires considerable skills and abilities. It requires knowledge and insight—about one's organization or entity, its people, goals, strengths and market niche. Yet, something more is needed. Leadership also requires a kind of awareness beyond the immediate, an awareness of the larger pictures—of paradigms that direct us, beliefs that sustain us, values that guide us and principles that motivate us, our worldviews. This article will, first, briefly examine how the concept of worldviews is used in leadership study and the contexts in which it arises. Second, it will critically look at worldviews, recognizing that they are not always coherent and that our belief systems are often fragmented and incomplete. Third, it will argue for the relevance of the concept worldview in leadership study as a way to explore various visions of life and ways of life that may be helpful in overcoming the challenges we face today. Fourth, it will examine how national and global issues impact worldview construction, especially among the millennial generation. Our conclusions set some directions for leadership action in light of worldview issues.
