Do Incentives Crowd Out Motivation? A Feasibility Study of a Community Vector-Control Campaign in Peru.

Incentives are a useful tool in encouraging healthy behavior as part of public health initiatives. However, there remains concern about motivation crowd out-a decline in levels of motivation to undertake a behavior to below baseline levels after incentives have been removed-and few public health studies have assessed for motivation crowd out. Here, we assess the feasibility of identifying motivation crowd out following a lottery to promote participation in a Chagas disease vector control campaign. We look for evidence of crowd out in subsequent participation in the same behavior, a related behavior, and an unrelated behavior. We identified potential motivation crowd out for the same behavior, but not for related behavior or unrelated behaviors after lottery incentives are removed. Despite some limitations, we conclude that motivation crowd out is feasible to assess in large-scale trials of incentives.

Medicaid Expansions and Crowd-Out: Evidence from HIFA Premium Assistance Programs.

OBJECTIVE: To evaluate the effect of the Oregon and New Mexico Health Insurance Flexibility and Accountability (HIFA) demonstrations. HIFA is an optional state Medicaid expansion targeted at adults and children with incomes below 200 percent of the federal poverty level (FPL). The study has five research questions: What type of health insurance do HIFA enrollees self report in surveys? What are the demographic characteristics of these enrollees? What type of health insurance coverage, if any, did HIFA enrollees have just prior to enrollment in the HIFA program? Among those with prior coverage, what prompted participation in the HIFA program? What type of health insurance, if any, would HIFA enrollees have in the absence of HIFA? METHODS: Data were collected via telephone interviews with a total of 406 enrollees from Oregon and 409 enrollees from New Mexico. The survey was conducted between July 7 and September 20, 2009, for both states. The sample frame for the survey was based on administrative records of adults enrolled in June 2009. After completion of the survey, active enrollment status as of the date the telephone interview was confirmed. Respondents no longer enrolled at the time of the survey (7 cases in NM and 14 in OR) were excluded from the analysis. The final sample size was 794 verified HIFA enrollees. RESULTS: HIFA enrollees tended to be middle-aged, male, and relatively unhealthy. Employment status varied tremendously from the self-employed to retired to unable to work. HIFA enrollees were reasonably well educated with 80 percent having at least a high school education. Most HIFA enrollees (90 percent) reported being uninsured just prior to participation in HIFA. Of those who were uninsured, most reported having been uninsured for an extended time-a year or more. Most enrollees joined HIFA because they lacked access to health insurance or could not afford insurance on the private market. The overwhelming majority (76 percent) of respondents believed that they would be uninsured in the absence of HIFA, with few considering either an employer plan or private purchase to be a viable option. Over 90 percent of enrollees correctly indicated they had insurance coverage. However, characterization of the type of coverage was problematic, particularly in the absence of the program-specific name. CONCLUSIONS: HIFA enrolled a relatively sick, male, middle-aged population that tended to have been long-term uninsured--the kind of enrollees for which the programs were designed--with little apparent crowd-out of private insurance. The reported health status coupled with low incomes suggests that individual purchase is unlikely, a sentiment echoed by the respondents. In the absence of HIFA, most enrollees believed they would rejoin the ranks of the uninsured from where they came.

Informality and the expansion of social protection programs: evidence from Mexico.

Many countries are moving from employer-based to universal health coverage, which can generate crowd out. In Mexico, Seguro Popular provides public health coverage to the uninsured. Using the gradual roll-out of the system at the municipality level, we estimate that Seguro Popular had no effect on informality in the overall population. Informality did increase by 1.7% for less educated workers, but the wage gains for workers who switch between the formal and the informal sector were not significantly affected. This suggests that marginal workers do not choose between formal and informal jobs on the basis of health insurance coverage.
