Achieving most goals demands cognitive control, yet people vary widely in their success at meeting these demands. Although motivation is known to be fundamental to determining success at achieving a goal, what determines motivation to perform a given task remains poorly understood. Here, we describe recent efforts toward addressing this question using the expected-value-of-control model, which simulates the process by which people weigh the costs and benefits of exerting mental effort. This model functionally decomposes this cost-benefit analysis and has been used to fill gaps in understanding of the mechanisms of mental effort and to generate novel predictions about the sources of variability in real-world performance. We discuss the opportunities the model provides for formalizing hypotheses about why people vary in their motivation to perform tasks, as well as for understanding limitations in researchers’ ability to test these hypotheses using a given measure of performance.

Addiction Care

INTRODUCTION:Due to their chronic nature and high prevalence, alcohol and cannabis addiction leads to a significant (disease) burden and high costs, both for those involved and for society. The latter includes effects on health care, quality of life, employment, criminality, education, social security, violence in the public and private domain, and traffic accidents. In the Netherlands, a considerable number of people with an alcohol or cannabis addiction currently do not receive addiction care. Cognitive Behavioral Therapy (CBT) is effective as a treatment for both alcohol and cannabis addiction and is widely used in specialized addiction care centers. This social cost-benefit analysis (SCBA) models costs and benefits of increasing the uptake of CBT for persons with an alcohol addiction and for adolescents with a cannabis addiction, taking into account a wide range of social costs and effects (1).METHODS:The method follows general Dutch guidance for performing SCBA. A literature search was conducted to evaluate efficacy of CBT for alcohol and cannabis dependence. In addition, the social costs of alcohol and cannabis addiction for society were mapped, and the costs of enhancing the uptake of CBT were explored. Costs and benefits of increased uptake of CBT for different social domains were modeled for a ten year period, and compared with current (unchanged) uptake during this period. Compliance problems (about 50 percent of clients do not finish CBT) and fall-back to addiction behavior (decrease of effects of CBT over time) were taken into account in model estimations.RESULTS:Per client treated with CBT, the estimated benefits to society are EUR10,000-14,000 and EUR9,700-13,000, for alcohol and cannabis addiction, respectively. These benefits result from reduced morbidity and mortality, improved quality of life, higher productivity, fewer traffic accidents, and fewer criminal activities.CONCLUSIONS:This SCBA shows that not only treated clients but also society will benefit from an increase in people treated with CBT in specialized addiction care centers.

To the Editor.— I would like to commend Walker and colleagues1 for their comprehensive examination of the costs and benefits of neonatal intensive care for infants weighing less than 1,000 grams. However, examining only one group of infants served by a tertiary neonatal intensive care unit (NICU) can be misleading. By definition, a tertiary level NICU is designed to provide a broad range of services to infants with a wide variety of illnesses. As is true for any system expected to provide a broad range of services, some services will result in a more favorable cost-benefit ratio than others.

This paper offers a general guide on how to conduct a proper economic analysis for community-based intervention projects. Identification and quantification of costs and benefits are the focus of the cost benefit analysis. We categorize costs and benefits from human and physical perspectives and pay special attention to the measures of saving human lives accompanied by the proposed calculation methods. We recommend net present value and benefit-cost ratio as the criteria to assess projects and highlight some challenges remaining in the analysis.

AbstractObjectives:To determine whether the cost of a statewide smoking cessation program in Pennsylvania could be justified by the benefits.Methods:A cost-benefit analysis of statewide access to smoking cessation programs. We compared three treatment alternatives, both with and without counselling: nicotine replacement therapy, bupropion and varenicline.Results:While the retail price of a pack of cigarettes in Pennsylvania is on average US$4.72, the combined medical costs and productivity losses in Pennsylvania attributable to each pack of cigarettes sold are approximately US$23.78 per pack of cigarettes. The ratio of benefits to cost varied from US$0.97 to US$2.76 saved per dollar spent on smoking cessation programs, depending upon the type of intervention.Conclusions:For most smoking cessation treatments, the benefits of a statewide smoking cessation program in Pennsylvania would greatly outweigh its costs.

The Cost

This paper presents the operational procedures involved in incorporating the environmental costs in the cost–benefit analysis of a hydro-electric project. The proposed project, if implemented, would result in the loss of 2,800 hectares of tropical forests and dislocation of two settlements of about 200 families who are currently dependent on the forests for their livelihood. The forests are mainly used for extracting reed – a material used both by traditional artisans and the paper-pulp industry. The potential environmental costs and benefits of the project are identified and approximate estimates of some of these costs are made for items such as carbon sequestration, bio-diversity, and so on, based on similar estimates made elsewhere. These estimated environmental costs are incorporated into the analysis, and the hypothetical estimate of the non-use value, which would make the project's net benefit zero, is estimated under different discount rates. The analysis brings into sharp focus some crucial factors that have a direct bearing on the social trade-off involved in the project choice.
