The impacts of product-harm crises on other firms in the same category are complex considering the combined spillover and customer encroachment effects. With responding to both effects, non-focal companies may adjust their social media strategies to attenuate the negative influence from product-harm crises and to exploit the benefit from their competitor’s misfortune. Using daily social media a...

Longitudinal studies of white female headship over the past few decades do not find significant welfare effects but do find a positive relationship between state fixed effects and welfare benefit levels. In other words, although white female headship does not respond to the year-to-year changes in welfare benefit levels, states with the most generous welfare benefits tend to be the states with ...

The Health Implications of Social Pensions: Evidence from China’s New Rural Pension Scheme* This paper estimates the causal effect of income on health outcomes of the elderly and investigates underlying mechanisms by exploiting an income change induced by the launch of China’s New Rural Pension scheme (NRPS). Using this policy experiment, we address the endogeneity of pension income by applying...

There is still much uncertainty about the impact of income inequality on health and mortality. Some studies have supported the original hypothesis about adverse effects, while others have shown no effects. One problem in these investigations is that there are many factors that may affect both income inequality and individual mortality but that cannot be adequately controlled for. The longitudin...

In this paper, we study the economic impact of user generated contents (UGC) in twitter on movies’ box offices. In contrast to other UGC such as online reviews, twitter more truthfully documents a product’s word of mouth (WOM) among ordinary consumers. We develop a new text mining technique to extract and analyze the movie conversations among twitter users. This mining technique is specially-de...

With the rapid development of social network and multimedia technology, customized image and video stylization has been widely used for various social-media applications. In this paper, we explore the problem of exemplar-based photo style transfer, which provides a flexible and convenient way to invoke fantastic visual impression. Rather than investigating some fixed artistic patterns to repres...

Theories about neighbours’ influence on children based on social capital, cohesion and disorganisation stress the importance of neighbourhood stability. However, amongst the vast number of studies on the effect of neighbours on a child’s education, none has tested whether neighbourhood stability matters. We fill this gap by estimating the causal effect of residential turnover on student test sc...

The study analyses the gender pay gap in private-sector management positions in Germany based on data from the German Socio-Economic Panel Study (SOEP) for the years 20012008. It focuses in particular on gender segregation in the labor market, that is, on the unequal distribution of women and men across different occupations and on the effects of this inequality on earnings levels and gender wa...

This paper develops and tests a simple model of parental allocations which stresses the effi ciency-equity tradeoff they face when investing in children of varying ability. The empirical component of the paper focuses on inequalities in schooling and child labour. Using siblingbased fixed effect models, I show that large differences in IQ test scores between siblings do not translate into large...

Social network data often involve transitivity, homophily on observed attributes, community structure, and heterogeneity of actor degrees. We propose a latent cluster random effects model to represent all of these features, and we develop Bayesian inference for it. The model is applicable to both binary and odel-based clustering mall world network cale-free network non-binary network data. We i...
