【报告摘要】
Consumers increasingly start their online price searches from a specific retailer. This paper aims to determine the impact of such a prominent retailer on channel members and consumers. We establish a search model within a distribution channel, where consumers sequentially search for prices across retailers. The results show that search prominence has two effects: First, it de-escalates price competition among retailers under duopoly but intensifies competition under oligopoly; second, it worsens the channel coordination between the manufacturer and the prominent retailer. Compared with the scenario without prominence, (1) in a duopoly, all channel members’ prices decrease in search costs. The manufacturer (prominent retailer) is worse (better) off, whereas the non-prominent retailer is better off if the proportion of costly search consumers is low. (2) In an oligopoly, (a) whereas the wholesale price decreases in search costs, the prominent retailer’s price first increases and then decreases in search costs; (b) non-prominent retailers are always worse off; and (c) prominence can lead to either win-win or lose-lose outcome for the manufacturer and the prominent retailer. (3) Although search prominence does not necessarily hurt the channel profit or social surplus, it always results in a decrease in consumer surplus.

【报告摘要】
Using Yu’s (2011) bottom-up approach, we show that U.S. aggregate disagreement is a strong predictor of macroeconomic conditions. Whereas conventional uncertainty measures rise in bad times, U.S. aggregate disagreement peaks around nine months before recessions. In non-U.S. global markets, an increase in U.S. aggregate disagreement is associated with long-lasting declines in economic activities, whereas non-U.S. aggregate disagreement does not have the predictability. Further, U.S. aggregate disagreement significantly predicts future stock market returns in the U.S. and non-U.S. markets, whereas non-U.S. aggregate disagreement displays limited predictive ability. The results highlight a leading role of U.S. aggregate disagreement on global economy and financial markets.

【报告摘要】
A key challenge for retailers is deciding whether to sell only the excellent coproducts (i.e., a dedicated sales strategy) or offer both excellent and good coproducts (i.e., a diverse sales strategy). We explore a scenario in which a retailer sells vertically differentiated coproducts—either excellent or good quality—to quality-sensitive consumers, ordering inputs of excellent initial quality from the supplier. The supplier determines the production and wholesale prices, while the retailer decides on the product line design, purchase quantities, and retail prices. Our analysis shows that the retailer will only offer premium products (excellent quality) if the proportion of excellent coproducts is sufficiently small and the supplier’s cost is at an intermediate level, or if the proportion of excellent coproducts is large enough and the supplier’s cost is low enough. In all other cases, the retailer will opt to sell products with heterogeneous quality levels. Furthermore, we explore how the retailer’s choice of sales strategy impacts product wastage and consumer surplus.

【报告摘要】
股利政策是公司财务理论研究的核心话题之一。Lintner(1956)指出,企业采用稳定、增长的股利政策,以迎合投资者的偏好。以此为前提,股利的变动才有经济意义,如信号传递效应。我国资本市场股利政策不断变化,从早期无管制到后来强制分红,上市公司股利政策也在发生改变,相应的研究从最初公司股利政策的决定因素、经济后果,到股利政策的信号效应等。但是,对我国资本市场股利政策的讨论,仍然缺乏对股利基本特征的研究,使得相关结果的支撑不足。本文在总结我国制度背景的基础上,分析了上市公司的股利特征。数据表明,股利政策逐渐成为一项正式的财务政策。结合股利的市场反应等,研究发现目前股利的信号作用有限。
