Online product ratings offer consumers information about products. In this dissertation, I explore how the design of the rating system impacts consumers’ sharing behavior and how different players are affected by rating mechanisms. The first two chapters investigate how consumers choose to share their experiences of different attributes, how their preferences are reflected in numerical ratings and textual reviews, whether and how multi-dimensional rating systems affect consumer satisfaction through product ratings, and whether and how multi-dimensional rating systems affect the interplay between numerical ratings and textual reviews. The identification strategy of the observational study hinges on a natural experiment on …

近些年来,我国城市化进程不断加快,到2020年我国常住人口城镇化率将达到60%左右,户籍人口城镇化率将会达到45%左右。伴随着我国城市化进程的高速推进以及经济水平的不断提高,公共物品及服务的需求程度加大,政府单独出资建设公共项目会导致资金不足、经营管理效率低下等问题。与此同时,我国当前不同层级地方政府的政府性债务都达到了一个非常高的水平,截至2017年末,中国地方政府债务16.47万亿元,债务率(债务余额/综合财力)为76.5%,其中地方负有偿还责任的债务约12.9万亿,地方政府性债务的控制和转化成为经济新常态下重要特征之一。在地方债务压力较大的情况下,PPP将替代土地财政和地方政府融资,为我国新型城镇化建设提供可持续的资金支持,PPP模式成为当前城市建设领域融资的重要选项。 据此,本文基于实证研究方法探讨在债务约束的背景下,在地方政府债务约束下,PPP模式的引入,对城市规划中建设用地面积、人口规划规模与容量、建设用地属性等的城市规划变量的影响;与此同时,考虑到地方政府的政策很大程度上受到是由地方官员,特别是受到作为地方政府党政“一把手”的市委书记和市长的晋升压力和激励的影响,讨论市委书记/市长的晋升压力和激励对PPP模式引入效果的影响。研究发现,在地方政府债务约束下,PPP模式的引入,显著增加城市规划中建设用地面积、人口规划规模与容量、建设用地属性等的城市规划变量;同时,地方政府官员存在利用PPP放大城市建设和规划规模的行为,反映了PPP项目在引入和使用的过程中很大程度上受政府官员的激励的影响。 Dissertation/Thesis
