汇率制度选择理论的回顾与展望

汇率制度选择一直是国际金融领域备受关注的一个问题.文章对汇率制度选择的研究方法及视角进行了总结,并对传统的汇率制度选择理论和汇率制度的新进展进行了论述,进而对未来汇率制度选择的研究进行了展望.认为:由于存在"恐浮",应该依据实际实行的汇率制度而不是官方宣布的汇率制度进行研究;从动态角度进行汇率制度转换的研究也是很重要的发展方向;应该对中间与两极汇率制度进行统一的界定,建立支持或反对"中空论"的严格理论框架.     

Do depicted suggestions of portion size on‐pack impact how much (un)healthy food children consume

In previous decades, portion and pack sizes of many foods tended to increase while, more recently, some foods started to downsize. These changes in actual portion sizes typically get coverage but less attention is given to the suggested portion sizes for multi‐serving food packages, and to what the impact is of the depicted portion sizes on‐pack. Using two studies with a mixed experimental design among young children, this paper examines the effects of depicted suggestions of portion size manipulation (regular vs. large—‘large’ corresponds to how brands typically depict portions). Both studies used a 2 × 2 × 2 crossover design, with the suggested portion size and food type as within‐ and order as between‐subjects manipulation. In Study 1, we used snacks (grapes and chocolate nuts). In Study 2, we compared two bread spreads (chocolate and cheese). In both the studies, we found that children ate more when presented with the larger depiction of the suggested portion size compared to the regular one. In Study 1, however, we found that children consumed more calories from the chocolate nut than the grape snack, while children did eat more grams of this healthier grape snack. We also showed that consumption in grams only differed between portion sizes when given grapes, which might be due to a possible ceiling effect of chocolate nut consumption. In Study 2, we also found a main effect for spread type as children ate more of chocolate compared to cheese spread. Our results indicate that this subtle on‐pack cue is persuasive. Moreover, policy makers and also marketers could use these insights to stimulate healthy eating in children.     

Fast food,ads, and taste in a Russian child’s mind

Research demonstrates that brands can influence children’s food preferences and potentially contribute to unhealthy consumption patterns. This article extends this line of research by investigating the complex and interacting effects of food brand marketing on experienced taste. The empirical field in a remote Russian town enabled the assessment of branding effects when entering a newly established market. Examining the combination of various advertisement features with emotional brand elicitation, we derive hypotheses about the interplay of brands and advertisement components linked to the perceived taste of a fast food meal. In Novosibirsk, Russia, 778 children and adolescents aged 10–18 years were exposed to fast food advertisements with real and imaginary brand logos and varying advertising claims. The advertisements consisted of a warning, an exaggerated credence claim, or both. A subsequently offered fast food meal—a portion of French fries—was experimentally varied and prepared to be either healthier but less tasty and unsalted, or less healthy but tastier and salted. The findings verify strong and positive brand effects on children’s taste satisfaction. Warnings in advertisements “worked” only for novel fast food brands by negatively affecting taste satisfaction, but increased taste satisfaction when applied in advertisements for established brands. Single credence claims did not improve the taste experience, but counteracted the negative effects of warnings for novel brands. Finally, the established brand influenced taste satisfaction positively when the fries were saltier. The findings reveal various opportunities for fast food marketing to artificially create taste satisfaction for potentially unhealthy food. Public health strategies that focus on advertising claim restrictions should be reconsidered in the context of possible evasion strategies of the food industry and counter‐effects of warnings among strong fast food brands.     

Land fragmentation,women empowerment and school dropout of children in Vietnam

This study examines the effect of land fragmentation on school dropout of children in Vietnam. To address the endogeneity issue, the study proposes an instrumental variable – that is land per capita at the commune level. The study also uses another instrumental variable – the percentage of land plot acquisition before 1993 – to check the robustness of the results. The findings are that higher land fragmentation decreases child school dropout. Land fragmentation has significant impacts on school dropout of children aged 10–15, however, it does not have any impact on school dropout of children aged 6–10. We explain these findings through one particular mechanism – that is women empowerment. A higher level of land fragmentation increases women empowerment in deciding to visit family, friends or relatives, the purchase of daily goods, large purchases, their own health, and their children’s health. A variety of robustness checks corroborate these findings.     

Vertical transmission of overweight: Evidence from a sample of English adoptees

Vertical influences can significantly shape children overweight by affecting both genetics and the environment children are exposed to. This paper examines the vertical (parental) transmission of child overweight drawing upon a fifteen year sample of English adults and their children, both adopted and biological, for which we can retrieve clinical measures height and weight. We find that, when both parents are overweight, children exhibit an increased likelihood of overweight, irrespective of whether they are adopted or biological children. When both parents are obese as opposed to overweight the picture is different. We find that the likelihood of child overweight increases by 16.7 percentage points among natural (non-adopted) children but only by 4.5 percentage points among adopted children. This suggests that the transmission of overweight when both parents are obese is not merely genetic, and what has been called vertical or parental transmission plays a non-negligible role. Our findings are validated by are a battery of robustness checks.
