Lose weight for a raise only if overweight: Marginal integration for semi‐linear panel models

Some studies have shown that body mass index (BMI), weight (kg)/height (m)², has a negative (or no) effect on wage. But BMI representing obesity is a tightly specified function of weight and height, and there is a room for weight given height (i.e. obesity given height) to better explain wage when the tight specification gets relaxed. In this paper, we address the question of weight effect on wage given height, employing two‐wave panel data for white females and adopting a semi‐linear model consisting of a nonparametric function of weight and height and a linear function of the other regressors. We find that there is no weight effect on wage up to the average weight, beyond which a large negative effect kicks in. Linear BMI models give the incorrect impression of the presence of a ‘wage gain’ by becoming slimmer than the average and of a ‘wage loss’ that is less than what it actually is when going above the average.

高龄人群移动信息终端产品设计研究

目前我国的消费市场上针对高龄人群所设计开发的移动信息终端产品非常少,这方面研究也极其有限。通过资料分析以及市场调查等手段对高龄人群的生理和心理两大方面进行研究,其中生理方面包括听力、视力、触觉和肌力,心理方面包括消费心理和认知心理。根据研究结果,分析归纳得出高龄人群移动信息终端产品设计的指导性设计原则。最后,以面向高龄人群的移动信息终端产品设计为实例,验证上述设计原则。     

Parents,migrant domestic workers and children's speaking of a second language: Evidence from Hong Kong

This paper explores the effects of different language home environments provided by English‐speaking and non‐English‐speaking migrant domestic workers (MDW) on Hong Kong children's ability to speak English. Results show that English‐speaking MDW in working‐mother households increase children's likelihood of speaking English by 12% if the mother in the household does not speak English but by 25% if the mother in the household is capable of speaking English. Non‐English‐speaking MDW, however, are found to have little such effects. Age and education are two qualities of English‐speaking MDW that are significantly associated with improvements in children's English‐speaking ability and their English school subject.

Residential mobility with job location uncertainty

This paper investigates the relationship between job changes and residential mobility. A job change may be prompted by reasons unrelated to factors associated with housing consumption. However, a job change may lead to an adjustment to housing consumption, i.e., residential relocation. Previous studies find that job relocations are positively associated with residential mobility. This paper departs from previous studies by looking at the effects of an uncertain future job location on residential mobility and mobility expectation. It is conjectured that with the existence of costs of residential mobility, a household head's likelihood for changing jobs in the future dampens the household's propensity to move, but encourages the formation of mobility expectation. These conjectures are examined empirically using data from the Panel Study of Income Dynamics and they are confirmed.     

Leader–member exchange and follower creativity: the moderating roles of leader and follower expectations for creativity

We examined leader and follower expectations for creativity as moderators in the relationship between leader–member exchange (LMX) and follower creativity. The results of a survey among 193 leader–follower dyads from two high-tech companies in mainland China show that LMX positively relates to follower creativity, and that leader and follower expectations for creativity moderate this relationship. Specifically, the relationship between LMX and follower creativity is positive and significant when either leaders or followers, or both leaders and followers, set high rather than low expectations for creativity, with the highest level of follower creativity observed when leaders and followers congruently hold high creativity expectations. In contrast, the LMX–follower creativity relationship is blurred when leaders and followers congruently hold low expectations for creativity. We discuss the relevance of these results from theoretical and professional perspectives.
