A preliminary theoretical examination of the targeted public distribution system in India

A theoretical model of targeting in the public distribution system is set out. In any system of targeting there could be inclusion and exclusion errors. These errors could be reduced by search by the state. The state aims to minimise the costs of food administration subject to keeping the magnitude of the exclusion error bounded. Targeting involves a consideration of the objective poverty level, the official poverty level and the targeted poverty level by the state. The targeted poverty level could be less than the official poverty level if the extent of search is not adequate. The objective poverty level is an increasing function of the above poverty line issue price of food due to exclusion errors, a decreasing function of the procurement price of food and by definition the below poverty line issue price of food. The instruments in the hands of the state are the official poverty level, the above poverty line issue price for food, the procurement price of food and the extent of search. The comparative static implications of the model are set out.     

Examining the influencing factors of intention to share accommodations in online hospitality exchange networks

ABSTRACT

CouchSurfing is a free social-network-based online hospitality exchange network, aptly representing a new sharing economy phenomenon. Based on social capital theory and previous literature, this study attempts to answer why hosts help strangers without any expected economic benefit within online hospitality exchange networks. An empirical study based on a Web survey conducted with CouchSurfing hosts reveals that the most identified antecedents (enjoy helping, shared narratives, desire to make friends, and reciprocity) are significantly related to hosts’ intention to share accommodations. Interestingly, the overshadowing effect of trust in CouchSurfing on the intention to share accommodations is also found.     

Identification of Web User Segments Based on Beliefs about Online Ads

Online advertising has been one of the fastest growing industries worldwide, due to the increased number of Internet users. From the perspective of marketing management, identifying the profile of web users who click online ads will enable designers to create better online advertising campaigns. Hence, the main objectives of this article are (1) to segment web users based on their beliefs about online ads, (2) to identify personality traits of each segment, and (3) to investigate attitudinal and behavioral differences across segments about online ads. Data were collected through an online survey and by using cluster analysis, web users were segmented into three groups based on their beliefs about online ads: “Supporters,” “Neutrals,” and “Opponents.” Personality trait differences as well as attitudinal and behavioral differences among three segments were examined and significant differences were found in terms of their personality traits, such as variety seeking, market mavenism, and innovativeness.

Choice modelling with search and sort data from an interactive choice experiment

We present a highly structured, online, interactive choice environment containing a large number of alternatives, a search tool that eliminates alternatives that fail specified criteria, and a sort tool. A conceptual framework is developed that links tool usage and preference heterogeneity, and tested in the context of long-haul flight choice. Individuals who sort on price are more price sensitive; individuals who search on certain attributes have a greater marginal (dis)utility for that attribute; and individuals who perform certain non-price searches have a lesser price disutility. The method shows promise as a means for providing a richer picture of preference heterogeneity.

网上商品热销的影响因素探析——基于分位数回归的实证研究

本研究从网上销售的影响因素出发,采用搜索程序获取了淘宝网的4059个货架1周的销售数据,通过分位数回归方法对不同热门程度产品的价格、信誉、保障标记以及口碑的需求弹性进行了实证分析。研究结果表明,随着产品热门程度的提高,信誉的需求弹性不断增强,而价格、保障标记以及口碑的需求弹性却不断减弱。由此表明,产品的价格降低,保障标记级别和口碑的提升都能使销售趋于分散,而提高商家的信誉却能加速销售向热门产品集中,使得"热门更热"。

基于非线性效应的第三方支付平台兼容性研究

本文在设定网络外部性效用为符合梅特卡夫法则的非线性函数条件下，构建双寡头支付平台兼容和不兼容两种情况下的优化模型，探讨双寡头支付平台的兼容性策略选择问题。研究发现，规模对称的双寡头支付平台兼容之后，两家支付平台的利润、消费者效用及社会福利均会增加；银联成立后中国工商银行的银行卡业务利润得以提升也验证了模型结果。建议政府借鉴银联的成功经验，使银联在线成为各支付平台的聚合型平台，提高第三方支付清算系统的效率。
