The effect of shopping goals and in-store mobile device use on purchase outcomes in brick-and-mortar stores

The present study examines the effect of using a mobile device on search and evaluation by a shopper in a brick-and-mortar store. A conceptual model that proposes inter-relationships between shopping goals, the amount and type of in-store mobile device use, and purchase outcomes is developed. Data from a national quota sample of 1034 mobile shoppers is used to test hypotheses derived from the proposed model. The findings provide several new insights into the impact of in-store mobile device use on the consumer decision journey in a brick-and-mortar store. Depending upon the shopping goals of the consumer, the use of a mobile device by shoppers in a brick-and-mortar store can either decrease or increase search, lead to more deferred purchases or in-store-now purchases, and more online or physical store purchases. The study is among the first to model the pathway to purchase for mobile device assisted shoppers in brick-and-mortar stores.     

The roles of multiple channels in predicting website visits and purchases: Engagers versus closers

In today’s online environment, consumers and sellers interact through multiple channels such as email, search engines, banner ads, affiliate websites and comparison-shopping websites. In this paper, we investigate whether knowing the history of channels the consumer has used until a point of time is predictive of their future visit patterns and purchase conversions. We propose a model in which future visits and conversions are stochastically dependent on the channels a consumer used on their path up to a point. Salient features of our model are: (1) visits by consumers are allowed to be clustered, which enables separation of their visits into intra- and inter-session components, (2) interaction effects between channels where prior visits and conversions from channels impact future inter-session visits, intra-session visits and conversions through a latent variable reflecting the cumulative weighted inventory of prior visits, (3) each channel attracts inter-session and intra-session visits differently, (4) each channel has different association with conversion conditional on a customer’s arrival to the website through that channel, (5) each channel engages customers differently (i.e., keeps the customer alive for a next session or for a next visit within a session), (6) the channel from which there was an arrival in the previous session can have an enhanced ability to generate an arrival for the same channel in the current session (channel persistence), and (7) parsimonious specification for high dimensionality in a low-velocity, sparse-data environment. We estimate the model on easy-to-collect first-party data obtained from an online retailer selling a durable good and find that information on the identities of channels and incorporation of inter- and intra-session visits have significant predictive power for future visitation and conversion behavior. We find that some channels act as “closers” and others as “engagers”—consumers arriving through the former are more likely to make a purchase, while consumers arriving through the latter, even if they do not make a purchase, are more likely to visit again in the future or extend the current session. We also find that some channels engage customers more than others, and that there are interaction effects between the channels visited. Our estimates show that the effect of prior inventory of visits is different from the immediate prior visit, and that visit and purchase probabilities can increase or decrease based on the history of channels used. We discuss several managerial implications of the model including using the predictions of the model to aid in selecting customers for marketing actions and using the model to evaluate a policy change regarding the obscuring of channel information.     

数据生产理论——数据资源权利配置的基础理论

人类正在进入数据驱动的时代,数据成为社会的基础资源,但数据一直被认为处于公共领域并妨碍着数据权利化,困扰着数据资源利用秩序的建立。描述特定对象的数据并不是天然存在的,而是被生产出来的,并将数据价值（预测分析、发现新知）的实现过程界分为原始数据生产（采集）、数据集生产（汇集性处理）和数据分析（分析性处理）三种行为,并将前两个行为称为数据生产,提出数据生产理论。数据生产理论首先应区分数据生产和数据分析,原始数据的生产是建立在分析原材料提供者基础之上,应承认其价值并配置适当权利,以满足各种分析目的的数据集的生产。同时,数据生产还应区别数据来源,来源于个人的数据并不一定是个人生产的,只有个人在提供或创制了数据时才是数据的生产者。因此,数据生产理论是在将数据视为一种资源的情形下为数据上权利配置提供理论支撑,通过配置相应权利,构筑从原始数据生产者到数据集生产者,再到数据分析者的数据利用秩序。

上山下乡经历与家庭风险金融资产投资——基于断点回归的证据

本文使用中国家庭追踪调查(CFPS)2010年家庭和个人层面数据,考察了户主的上山下乡经历对于家庭风险金融资产投资决策的影响。结果表明,上山下乡经历显著提高了家庭对于股票及广义风险金融资产的投资概率和投资规模。机制分析表明,此经历主要通过提升家庭投资的风险偏好和投资能力来影响家庭的风险金融资产投资。分样本讨论结果表明,上山下乡经历对家庭风险金融投资产生的正向影响在高人力资本、高收入和高社会资本群体中更为显著。
