Short‐run subsidies for health products are common in poor countries. How do they affect long‐run adoption? A common fear among development practitioners is that one‐off subsidies may negatively affect long‐run adoption through reference‐dependence: People might anchor around the subsidized price and be unwilling to pay more for the product later. But for experience goods, one‐off subsidies could also boost long‐run adoption through learning. This paper uses data from a two‐stage randomized pricing experiment in Kenya to estimate the relative importance of these effects for a new, improved antimalarial bed net. Reduced form estimates show that a one‐time subsidy has a positive impact on willingness to pay a year later inherit. To separately identify the learning and anchoring effects, we estimate a parsimonious experience‐good model. Estimation results show a large, positive learning effect but no anchoring. We black then discuss the types of products and the contexts inherit for which these results may apply. 相似文献

Are ‘statistical households’, as defined in national censuses, able to describe the family environment in Africa? Do they correspond to the family units that individuals identify with? To address this issue, we build on a follow-up survey in south-east Mali, which links national censuses with local censuses at the individual level (N?≈?28,000 census observations). Three cross-sectional snapshots of family arrangements are compared: households recorded in national censuses, and family economic units and residential units recorded by local censuses. The national census household data appear poorly suited to documenting family living arrangements. They do not account for family economic units or residential units, but are highly conditioned by a normative representation centred on the nuclear family. Therefore, they fail to describe the complexity and diversity of people’s living spaces, making particular types of living arrangements invisible and increasing the likelihood of omitting individuals who do not fit into a nuclear model. 相似文献

The Gambling Attitudes and Beliefs Survey (GABS) is a questionnaire which explores gambling-related dysfunctional beliefs in an unidimensional way. The present research aims to investigate the dimensionality of the scale. 343 undergraduate student gamblers and 75 pathological gamblers seeking treatment completed the GABS and the south oaks gambling screen. Exploratory and confirmatory factor analyses revealed that the original one-factor structure of the GABS did not fit the data effectively. We then proposed a shorter version of the GABS (GABS-23) with a new five-factor structure, which fitted with the data more efficiently. The comparisons between students (problem vs. non-problem gamblers) and pathological gamblers seeking treatment indicated that the GABS-23 can discriminate between problem and non-problem gamblers as efficiently as the original GABS. To ensure the validity and the stability of the new structure of the GABS-23, analyses were replicated in an independent sample that consisted of 628 gamblers (256 non problem gamblers, 169 problem gamblers who are not treatment-seeking and 203 problem gamblers seeking treatment). Analyses showed satisfactory results, and the multidimensional structure of the GABS-23 was then confirmed. The GABS-23 seems to be a valid and useful assessment tool for screening gambling-related beliefs, emotions and attitudes among problem and non-problem gamblers. Moreover, it presents the advantage of being shorter than the original GABS, and of screening irrational beliefs and attitudes about gambling in a multidimensional way. The five-factor model of the GABS-23 is discussed based on the theory of locus of control. 相似文献

Level and type of impulsivity are essential variables to be taken into consideration during the initial evaluation of a pathological
gambler. The aim of this study was to measure the score for 4 impulsivity-related traits (Urgency, (lack of) Premeditation,
(lack of) Perseverance and Sensation seeking) in a sample group of at-risk and pathological gamblers, and to highlight any
links with certain elements of clinical data. The UPPS Impulsive Behaviour Scale was administered to 84 problem gamblers seeking
treatment. The severity of gambling disorders was evaluated using the diagnostic criteria of the DSM-IV. Psychiatric and addictive
comorbidities were also explored. The results indicated that the score for the Urgency facet had a positive correlation with
the severity of gambling disorders. It appeared that participants displayed different clinical profiles according to the level
and type of impulsivity. Several of the UPPS scales were identified as risk factors for mood disorders, risk of suicide, alcohol
use disorders, and Attention Deficit/Hyperactivity Disorder (ADHD). The results confirm both the complexity of the multi-dimensional
concept of impulsivity and the reason why the UPPS is of interest for a more in-depth study of the subject. 相似文献
