The valuation of American options in a multidimensional exponential Lévy model

We consider the problem of valuation of American options written on dividend‐paying assets whose price dynamics follow a multidimensional exponential Lévy model. We carefully examine the relation between the option prices, related partial integro‐differential variational inequalities, and reflected backward stochastic differential equations. In particular, we prove regularity results for the value function and obtain the early exercise premium formula for a broad class of payoff functions.     

Return Migration from Nineteenth Century Australia: Key Drivers and Gender Differences

This paper sheds new light on return migration from Australia to the UK in the latter nineteenth century. It uses data from shipping records, and from a random sample of the 23,000 Australian‐born in the 1911 Census of England and Wales. Based on these sources, it estimates some 20% of migrants to Australia returned: higher among the wealthy, but still 12% of semi‐ and unskilled working class migrants returned. There was a preponderance of women among returnees. From that, and other evidence such as the geographic spread of returnees across England, the paper argues that social networks played critical roles in decisions to return.     

Do gender identities of femininity and masculinity affect the intention to buy ethical products?

This study shows that gender identity affects ethical intentions. We investigate the intention to purchase ethical products through a survey study among young consumers in Italy. Measures of planned behavior, internal ethics, self-identity, and moral harm, together with proxies for individual gender identities of femininity and masculinity are included in our model of intention to purchase ethically. Results show that femininity significantly increases ethical intent, whereas masculinity has an opposite effect. These findings are robust to gender. In fact, the relations of femininity and masculinity on the intention to consume ethical products hold when the subsamples of males and females are considered. This study relates to the ongoing debate regarding the determinants of ethical decision-making and the feminine stereotype by extending the understanding of the attitude-intention gap in ethical consumption among young consumers in Italy. Finally, implications and avenues for further research are discussed.

中国农村地区时间贫困的性别差异研究

经济发展所提供的就业机会与社会性别分工所规定的家庭责任,使女性面临工作与家庭责任的双重压力。本文运用时间贫困的概念,即工作时间超过某一特定时间并且得不到足够休息与闲暇的情况,度量了农村地区男性与女性受时间这种稀缺资源的约束程度。通过分性别的时间贫困的回归分析,本文发现,农村已婚女性是最容易遭受时间贫困的人群,当地劳动力结构转移对男性与女性发生时间贫困的概率影响有所不同,女性受到的边际影响更大。     

Women's bodies,menstruation and marketing “protection:” interpreting a paradox of gendered discourses in consumer practices and advertising campaigns

This essay explores the various associations, conflicts, and resolutions that converge in consumer research to produce an advertising campaign for a feminine hygiene product. Ethnographic research identified a correspondence in beliefs and values among women who discuss menstruation as a natural process of rhythms and flow in their changing bodies. Building off the work of gender discourses in advertising, this paper claims women's “natural” discourse located in research differs from “protection” discourse in advertising, which holds a binary view of menstruation and associates menstruation socially with shame and secrecy. The research reveals that while women adopt a “natural” discourse of menstruation, discourses of “protection” still dominate marketing. Paradoxically, women incorporate both discourses in assemblages of constructing “feminine identities.” This research proposes a correspondence model that regards the consumption of consumer personal-care products in terms of embodiment rather than binary categories as a way to interpret such paradoxes.     

Communicating brand gender through type fonts

The marketing literature suggests that positioning a brand in terms of brand gender (i.e., brand masculinity and brand femininity) generates favorable consumer responses, yet there is little research on how brand gender perceptions arise. This research examines whether type font can be employed to create brand gender perceptions in the context of unfamiliar brands. Building on the theoretical framework of personality inferences based on static cues, three studies involving a range of type fonts, brand names, and product categories demonstrate that type font influences consumers’ perceptions of brand gender. Type font effects emerged for brand names presented in isolation (Study 1), brand names presented on signage (Study 2a), and brand names on product labels (Studies 2b and 3). Importantly, type font effects on brand gender persisted in the presence of a competing brand gender cue (i.e., brand name with gender associations), and type font and brand name influenced brand gender perceptions independently. A fourth study demonstrates that type fonts representing the brands influence consumers’ likelihood to recommend the brand. The article concludes with a discussion of theoretical and brand management implications.     

The sibling effect on the consumption of phone services

The peer effect is a relevant issue in studies on consumption habits and consumers’ behaviour. Indeed, the extant literature shows that peers and siblings affect individual decisions and choices, as people generally follow peers’ and siblings’ examples. In other words, people imitate their peers. Starting from the existing theoretical models and empirical evidence that suggest a relevant impact of peers on one's decisions, this article analyses how the presence and the gender of siblings affects one's consumption of phone services. I consider a sample of 500 European undergraduate students. In order to isolate the peer effect, I restrict the analysis to the use of the phone for talking with friends. The results show highlight a strong sibling effect, whose magnitude and whose sign depend on both the gender of the siblings and on that of the interviewee.     

The effects of body image and self‐esteem on frequency of closet cleaning

The purpose of this study was to examine divestment of clothing and its relationship to psychological characteristics (body image and self‐esteem) and demographic characteristics (gender and age) of the consumer. The relationship between frequencies in closet cleaning to categories selected for body image (Appearance Orientation, Appearance Evaluation, Body Areas Satisfaction, Subjective Weight, and Weight Preoccupation) were calculated using Pearson's Correlation and Analysis of Variance. Frequencies in closet cleaning were also compared to the overall score from responses to the Rosenberg Self‐Esteem Scale. The relationship between disposal frequency and Appearance Orientation was statistically significant for both gender groups, particularly among groups 18–25 years. Individuals with a higher Appearance Orientation tended to dispose clothing more frequently than others. When comparing men to women, body image accounted for garment disposal more among men, suggesting women have more varied reasons to dispose of clothing. Self‐esteem measures were not related to disposal frequency among all groups. The findings contribute to knowledge and have implications related to self‐concept and consumption behavior post purchasing. For example, results were similar between young men and women suggesting men may have similar clothing and appearance oriented behavior to women. In another example, those with high appearance orientation could be targeted for campaigns related to sustainable disposal strategies.     

Political Skill,Gender, and Social Network Positioning of Chinese Employees

We collected data from 156 Chinese hospital employees to investigate how political skill and gender affect their advice and friendship network positioning. We found employees with high levels of political skill are more likely to proactively seek friendship ties, while political skill does not affect employees’ advice networks overall. In addition, results show that for men, those with high levels of political skill have lower in-degree centrality in advice and friendship networks than those with less political skill. Political skill does not affect women’s network positions.
