Consumers frequently engage in pre-purchase search to extract up-to-date information for their purchase decisions. Search is an essential part of online comparison-shopping and decision-making process as it reduces purchase related uncertainty and increases the likelihood of purchase satisfaction. In this paper, we study how determinants of prepurchase search, purchase related uncertainty and t...

We construct an optimal execution strategy for the purchase of a large number of shares of a financial asset over a fixed interval of time. Purchases of the asset have a nonlinear impact on price, and this is moderated over time by resilience in the limit-order book that determines the price. The limit-order book is permitted to have arbitrary shape. The form of the optimal execution strategy i...

Customer lifetime value (CLV) measurement is challenging as it requires forecasting customers' future purchases. Existing stochastic CLV models for this purpose generally make the following assumptions: 1) purchase behavior of customers can be described by purchase frequency and the average monetary value of transactions, 2) customers keep the same purchase behavior pattern over time, 3) purcha...

an electronic health record system (EHR) for years but figured that it would be too costly and disruptive to your practice to actually buy one. You suspected that it would slow you down and force you to interact more with a computer than with the patient in front of you. You assumed that EHRs made sense only for technophile types who didn’t mind typing or fiddling with programs, and you were ri...

It is only an order quantity which is decided for a spot selling time in the classical newsboy problem. Both the purchase timing and the time-variant variance of the demand are neglected. When the vendor gives a price discount for early purchase, the buyer purchases the quantities of price discount at the cost of forecast bias. The buyer has to forecast the demand early before purchase ahead of...

Consumers have been spoiled by the quality of Halal products available on the market. However, existing literature has lacked recognition for consumer Halal cosmetic products. Therefore, this study enhances the body of knowledge about consumer attitude and intention to purchase Halal cosmetic products. Specifically, this article will discuss the moderating effect positioning has on attitude wit...

Large-scale datasets of consumer behavior might revolutionize the way we gain competitive advantages and increase our knowledge in the respective domains. At the same time, valuable datasets pose potential privacy risks that are difficult to foresee. In this paper we study the impact that the prices from consumers’ purchase histories have on the consumers’ location privacy. We show that using a...

T measurement of customer lifetime value is important because it is used as a metric in evaluating decisions in the context of customer relationship management. For a firm, it is important to form some expectations as to the lifetime value of each customer at the time a customer starts doing business with the firm, and at each purchase by the customer. In this paper, we use a hierarchical Bayes...

We propose a new topic model for tracking timevarying consumer purchase behavior, in which consumer interests and item trends change over time. The proposed model can adaptively track changes in interests and trends based on current purchase logs and previously estimated interests and trends. The online nature of the proposed method means we do not need to store past data for current inferences...
