We consider manufacturer rebate competition in a supply chain with two competing manufacturers selling to a common retailer. We fully characterize the manufacturers’ equilibrium rebate decisions and show how they depend on parameters such as the fixed cost of a rebate program, market size, the redemption rate of rebate, the proportion of rebate‐sensitive consumers in the market and competition intensity. Interestingly, more intense competition induces a manufacturer to lower rebate value or stop offering rebate entirely. Without rebate, it is known that more intense competition hurts the manufacturers and benefits the retailer. With rebate, however, more intense competition could benefit the manufacturers and hurt the retailer. We find similar counterintuitive results when there is a change in some other parameters. We also consider the case when the retailer subsidizes the manufacturers sequentially to offer rebate programs. We fully characterize the retailer's optimal subsidy strategy, and show that subsidy always benefits the retailer but may benefit or hurt the manufacturers. When the retailer wants to induce both manufacturers to offer rebate, he always prefers to subsidize the manufacturer with a higher fixed cost first. Sometimes the other manufacturer will then voluntarily offer rebate even without subsidy. 相似文献
The methodological issues of using self-reported human immunodeficiency virus (HIV) testing history to determine HIV infection status are understudied. This study aimed to assess the disparities between HIV testing history and self-reported HIV status, with a specific objective of estimating the prevalence of self-reported HIV-negative status in sexually active students who had never had an HIV test (inaccurate self-disclosure). Participants were recruited from four Hong Kong universities; 255 students were included in the analysis, with 16.1% of participants being men who have sex with men (MSM). Overall, 81.6% of participants reported they never had been tested for HIV, with inaccurate self-disclosure by 65.9% of participants. Among participants who used condoms inconsistently, only 20.2% had had HIV tests, with inaccurate self-disclosure by 66.7% of subjects. Among MSM students, only 36.6% had had HIV tests, with inaccurate self-disclosure by 61.0% of participants. Among MSM students who used condoms inconsistently, only 35.1% had had HIV tests, with inaccurate self-disclosure by 62.2% of participants. The findings raise concerns about the use of self-reported HIV status in clinical practice and research. The low prevalence of HIV testing found suggests that interventions to promote HIV testing should be continued. 相似文献
This paper empirically examines the disparities over time across six dimensions of poverty (monetary, education, health, housing, basic services, and durable assets) between ethnic minority and majority households in rural Vietnam. Using the five-wave panel data of the Vietnam Access to Resources Household Survey (VARHS) 2008–2016, we observe improvements in most non-monetary dimensions of poverty for both ethnic groups, while the monetary dimension shows the highest degrees of deprivation and the lowest rate of decrease during the studied period. Health is the only dimension in which ethnic minority households are not only better off than those of majority households during the studied period, but also report improvement. We further explore the role of social capital in ethnic minorities and non-minorities at household and community levels in multiple dimensions of poverty by employing multilevel models. Our study reports the significant effects social capital have at the community level on reducing poverty in the monetary, education, housing, and basic services dimensions for ethnic minorities, while social capital at the household level shows significant effects on monetary, basic services, and durable assets. These findings indicate that policy makers ought to consider the role of social capital when designing poverty alleviation strategies for the country.
Adolescents' antisocial behavior and negative conflict management styles are each associated with adverse romantic relationship outcomes, yet little research exists on their associations. We investigated whether adolescents' antisocial behavior was associated with conflict management styles, and whether it predicted breakup 3 months later. In total, 91 adolescent couples (Mage= 16.43, SD = 0.99; 41.2% Hispanic/Latinx) participated in videotaped conflict discussions coded for negotiation, coercion, and avoidance. Actor–partner interdependence models suggest adolescents' antisocial behavior is associated with decreased use of negotiation (couple pattern) and increased use of coercion (actor pattern). No significant associations were found for avoidance. Neither antisocial behavior nor conflict management styles predicted breakup. Findings are discussed in light of the unique developmental importance of adolescents' romantic relationships. 相似文献
The current study uses an accelerated longitudinal design to examine the role of three dimensions of academic engagement (behavioral, relational, and cognitive) in explaining the influence of English language proficiency on newcomer immigrant youths' academic performance across adolescence. The sample included 354 youth from Central America, China, the Dominican Republic, Haiti, and Mexico. As established with other populations, the behavioral, relational, and cognitive dimensions of academic engagement were closely associated to one another and significantly contributed to academic performance. Mediation analyses revealed that immigrant youth with limited English language proficiency were more likely to experience low levels of relational and behavioral engagement, which contributed to lower levels of academic performance over time. 相似文献
This article examines the link between local institutional quality in the home country and locational choices of international return migrants. We scrutinize the locational choices of Vietnamese return migrants to the south central and the south regions of Viet Nam in 2014. Binary and multinomial regression models are fitted to identify the influence of migrants’ individual attributes and the characteristics of regional destinations within Viet Nam. Our analysis reveals that both individual‐specific and region‐specific variables are significantly related to Vietnamese return migrants’ choices when registering for permanent residency back in their home country. More remarkably, we provide compelling evidence of the positive role of institutional quality at the local level in these migration decisions. Moreover, the effect of institutional quality differs with the characteristics of migrants: regions with better institutional quality are more attractive both to younger return migrants and to those who returned from host countries with better institutional quality. 相似文献
An “inhabited” approach to the study of institutions examines how organizational actors produce locally distinctive meaning in response to similar institutional forces. Adopting inhabited institutionalism to the study of campus sexual life, this study draws on interviews with 54 undergraduate women at two four‐year universities in the United States—Ivy U and State U—to show campus cultures unique to a university inform women's decisions to engage in hookups and/or relationships. For women attending Ivy U, an elite institution where pressure to succeed is palpable, both hookups and long‐distance relationships alike are posited as advantageous for the time‐crunched, preprofessional student. At State U, a public school with a party reputation, women explain their engagement in hookups as part of the “fun” of college life, while women seeking or involved in committed relationships are obligated to negotiate the effects of the party culture in their partnerships. This study challenges the notion of a monolithic sexual culture across university settings by showing how campus cultures cultivated at the local level create unique organizational conditions within which undergraduate women forge and explain their engagement in hookups and relationships alike. 相似文献
The authors evaluated the extent to which the short‐term effect of late life widowhood on parent–child relationships is moderated by 5 personality traits—Extraversion, Agreeableness, Conscientiousness, Emotional Stability, and Openness to Experience—and how these interactive effects differ by gender. Data were from the Changing Lives of Older Couples Study (N = 1,532). The results indicated that the effects of widowhood on positive and negative interactions with children were significantly moderated by Agreeableness, Extraversion, and Openness to Experience. An agreeable personality helped widowed persons receive more positive interactions, whereas Openness to Experience reduced negative interactions. Widowed persons with higher Extraversion reported more negative interactions. Furthermore, moderating effects of Extraversion and Openness to Experience differed by gender; specifically, higher Extraversion scores predicted increased positive interactions with children for widowed women but decreased positive interactions for widowed men. The significant association between Openness to Experience and decreased negative interactions with children was more apparent among men than among women.相似文献
College women are at a high risk of sexual assault. Although programs that aim to change bystander behaviors have been shown to be potentially effective in preventing sexual assault on campuses in the United States, little is known about bystander behaviors outside of the United States. The purpose of this study was to explore and compare factors affecting bystander behaviors regarding sexual assault intervention and prevention among undergraduate students in the United States, Japan, India, Vietnam, and China. A total of 1,136 students participated in a self-reported survey. Results demonstrate substantial variations across countries. Bystander behaviors are associated with multilevel factors, including gender, knowledge of individuals who have experienced a sexual assault, and knowledge about campus or community organizations. 相似文献
