Effectiveness of Monetary Incentives in Modifying Dietary Behavior: A Review of Randomized, Controlled Trials

NUTRITION REVIEWS, Issue 12 2006
FAFPHM, Joanne Wall MBChB
To review research evidence on the effectiveness of monetary incentives in modifying dietary behavior, we conducted a systematic review of randomized, controlled trials (RCTs) identified from electronic bibliographic databases and reference lists of retrieved relevant articles. Studies eligible for inclusion met the following criteria: RCT comparing a form of monetary incentive with a comparative intervention or control; incentives were a central component of the study intervention and their effect was able to be disaggregated from other intervention components; study participants were community-based; and outcome variables included anthropometric or dietary assessment measures. Data were extracted on study populations, setting, interventions, outcome variables, trial duration, and follow-up. Appraisal of trial methodological quality was undertaken based on comparability of baseline characteristics, randomization method, allocation concealment, blinding, follow-up, and use of intention-to-treat analysis. Four RCTs were identified as meeting the inclusion criteria. All four trials demonstrated a positive effect of monetary incentives on food purchases, food consumption, or weight loss. However, the trials had some methodological limitations including small sample sizes and short durations. In addition, no studies to date have assessed effects according to socioeconomic or ethnic group or measured the cost-effectiveness of such schemes. Monetary incentives are a promising strategy to modify dietary behavior, but more research is needed to address the gaps in evidence. In particular, larger, long-term RCTs are needed with population groups at high risk of nutrition-related diseases [source]

Equity in Toxic Tort Litigation: Unjust Enrichment and the Poor,

LAW & POLICY, Issue 2 2004
ALLAN KANNER
This paper proposes to explore the current and prospective role of equitable theories and remedies in toxic tort litigation. The argument is for an unjust enrichment remedy in certain property pollution cases. The idea is to remove the monetary incentive for polluting economically depressed areas. Two specific areas of investigation come immediately to mind. First, courts have already embraced equitable remedies to address pollution damages. Under Ayers and its progeny, many states have allowed the equitable remedy medical monitoring. What is important to understand is how legal relief for increased risk claims would have been inadequate and also the propriety of finding an equitable approach. Second, moving from personal injury to real property damage claims, we see a similar opportunity for use of equitable relief under an unjust enrichment theory. Currently, there is much debate about the propriety of restoration damages as opposed to fair market value (FMV) damages for the landowners whose property is damaged by the pollution of another. Each approach has various strengths and weaknesses. A better approach might be to use unjust enrichment on a law and economics basis as a remedy to force polluters to internalize the cost of pollution. For instance, take a polluter who pollutes the neighboring environs in lieu of paying one million dollars in disposal and storage costs. Assume the neighboring properties are only worth three hundred thousand dollars on a FMV approach. Assume further that restoration costs are ten million dollars, but that the relevant government agency would accept a natural attenuation clean-up approach. How should the remedy be set, and should one consider allowing a de facto pollution easement? [source]

Determinants of mail-survey response: Survey design factors and respondent factors

PSYCHOLOGY & MARKETING, Issue 3 2002
James G. Helgeson
With the use of a hierarchy-of-effects model, the decision to complete a mail survey was modeled as a process moving through several stages. A set of variables thought to influence the survey-completion decision process was examined. These variables include survey design factors, which were manipulated by the researchers, and respondent factors, such as attitudinal and personal constructs. Based on the research findings, the hierarchy-of-effects model is an appropriate way to model the mail-survey-response process. The data indicate that among the survey design factors included in the study, the monetary incentive had the most effect on the decision process, with a pervasive impact throughout the process. Importantly, respondent factors such as attitude toward research were of critical importance in moving respondents through the survey-response process. Research into the response-rate phenomenon is likely to benefit by considering how both survey design and respondent factors affect specific stages of the response process and enhance participation in surveys. © 2002 Wiley Periodicals, Inc.

Improving substance abuse treatment enrollment in community syringe exchangers

ADDICTION, Issue 5 2009
Michael Kidorf
ABSTRACT Aims The present study evaluated the effectiveness of an intervention combining motivational enhancement and treatment readiness groups, with and without monetary incentives for attendance and treatment enrollment, on enhancing rates of substance abuse treatment entry among new registrants at the Baltimore Needle Exchange Program (BNEP). Design Opioid-dependent study participants (n = 281) referred by the BNEP were assigned randomly to one of three referral interventions: (i) eight individual motivational enhancement sessions and 16 treatment readiness group sessions (motivated referral condition,MRC); (ii) the MRC intervention with monetary incentives for attending sessions and enrolling in treatment,MRC+I); or (iii) a standard referral condition which directed participants back to the BNEP for referral (standard referral,SRC). Participants were followed for 4 months. Findings MRC+I participants were more likely to enroll in any type of treatment than MRC or SRC participants (52.1% versus 31.9% versus 35.5%; ,2 = 9.12, P = 0.01), and more likely to enroll in treatment including methadone than MRC or SRC participants (40.4% versus 20.2% versus 16.1%; ,2 = 16.65, P < 0.001). MRC+I participants also reported less heroin and injection use than MRC and SRC participants. Conclusions Syringe exchange sites can be effective platforms to motivate opioid users to enroll in substance abuse treatment and ultimately reduce drug use and number of drug injections. [source]

Knowledge Market Design: A Field Experiment at Google Answers

JOURNAL OF PUBLIC ECONOMIC THEORY, Issue 4 2010
YAN CHEN
In a field experiment at Google Answers, we investigate the performance of price-based online knowledge markets by systematically manipulating prices. Specifically, we study the effects of price, tip, and a reputation system on both an answerer's effort and answer quality by posting real reference questions from the Internet Public Library on Google Answers under different pricing schemes. We find that a higher price leads to a significantly longer, but not better, answer, while an answerer with a higher reputation provides significantly better answers. Our results highlight the limitation of monetary incentives and the importance of reputation systems in knowledge market design. [source]

Access as a Motivational Device: Implications for Human Resource Management

KYKLOS INTERNATIONAL REVIEW OF SOCIAL SCIENCES, Issue 2 2003
Pablo Arocena
Summary In this paper we analyse the provision of incentives at work on the basis that the employment relationship is not solely an exchange of work for money. Particularly, in addition to a salary, a job also gives access to a working experience, which determines the potential for employee's human capital acquisition and for his social and professional recognition. Accordingly, we argue that the level of access defines the employee's opportunities for satisfying his self-actualisation and achievement needs. Further, given that the firm has the ability to regulate access by way of a number of organisational decisions, access becomes a powerful mechanism to activate the worker's internal motivation. In this respect, the main purpose of this paper is to study the effect of access and intrinsic motivation on employee's performance and job design. To that effect, we analyse the economic consequences of our arguments on access through a model of agency enriched with a number of psychological and organisational considerations. Our results and conclusions are consistent with much of the interdisciplinary research on the subject, as well as with the evidence emerging from the real business practice. They also provide a number of practical implications for personnel policies. First, in order to activate the individual's internal motivation, the job must reach a minimum value. Second, the positive effect of the employee's intrinsic motivation on effort decreases with the magnitude of monetary incentives. Third, the efficiency gains generated by the extension of job access increase with the employee's level of perceived risk. Finally, the costs of selection are a consequence of granting access.

Effectiveness of Monetary Incentives in Modifying Dietary Behavior: A Review of Randomized, Controlled Trials

The effects of objective feedback on performance when individuals receive fixed and individual incentive pay

PERFORMANCE IMPROVEMENT QUARTERLY, Issue 3-4 2008
Douglas A. Johnson
We examined whether objective feedback would enhance performance when individuals were paid monetary incentives. A two-by-two factorial design was used, with 123 college students assigned to incentive pay without feedback, incentive pay with feedback, fixed pay without feedback, or fixed pay with feedback. Participants attended six sessions and entered the cash value of simulated bank checks presented on a computer. Two-factor ANCOVAs were used to determine whether the number of checks completed correctly and time spent working differed. The number of checks completed correctly during a pretest was used as the covariate to control for keyboard proficiency. Incentives increased the number of checks completed correctly by 34 percent (p<.001, standardized effect size=.91); however, feedback had no effect (p=1.00). The incentives increased the time spent working by 31 percent (p<.001, standardized effect size=1.13); however, again feedback had no effect (p=1.00). Although speculative, the results imply that feedback per se, absent evaluation, is unlikely to increase performance even when correlated with performance-contingent rewards. [source]

Task-dependent changes in frontal brain asymmetry: Effects of incentive cues, outcome expectancies, and motor responses

PSYCHOPHYSIOLOGY, Issue 3 2001
Anita Miller
The current study was designed to clarify the psychological functions most closely associated with frontal brain asymmetry. Electroencephalography (EEG) was recorded from 60 participants while they performed a delayed reaction time (RT) task that included manipulations of incentive, expectancy, and response. Significant alpha asymmetry effects were reflected in topographic differences across anterior EEG sites. Variations in monetary incentives resulted in parametric changes in anterior frontal alpha asymmetry. Manipulations of outcome expectancies were related to mid-frontal EEG changes that differed for men and women. Varied response requirements were related to central asymmetry patterns. Taken together, the findings suggest that regionally specific patterns of frontal asymmetry are functionally related to particular aspects of approach,withdrawal tendencies involved in the temporal guidance and regulation of goal-directed behavior.
