Conventional random-coefficients models of conditional brand choice using panel data ignore the dependence of the random-coefficients distribution on the purchase frequencies. We show that this leads to biased estimates and propose a conditional likelihood approach to obtain unbiased estimates. Unlike alternative approaches that require observation of “no-purchase” occasions, our proposed metho...

With the rapid development of the Internet and e-commerce, the Internet has become an important channel for consumers to purchase goods. Because online shopping has characteristics of virtual and remote presence, consumers take greater psychological risks while they purchase online and they will make more cautious purchasing decisions. So they build their confidence and reduce the perceived ris...

Because online shopping has characteristics of virtual and remote presence, consumers take greater psychological risks while they purchase online and they will make more cautious purchasing decisions.

Multiple studies have attempted to explain the online shopping behaviour of consumers both in Information Systems (IS) and Marketing literature. However, given the widening gap between actual and expected increase in Internet-enabled or web-based consumer purchase transactions, the need to investigate the underlying factors for on-line purchase behaviour assumes increased significance. Also, th...

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...

This paper aims to incorporate the diffusion of innovation theory and conformity theory to explain consumers’ green purchase intentions. To this end, a conceptual model has been proposed and subjected to empirical verification with the use of a survey method. Using a sample of Taiwanese consumers who had the actual purchase experience of green detergents, this study employed structural equation...

The cliché " once a homeowner, always a homeowner " is not true. We study the causes of terminations of spells of first-time homeownership. Using a national panel data set, we find that the likelihood of a household terminating a spell of homeownership is predictable at the time of purchase. Specifically, the lower the probability score that a household becomes an owner at the time of purchase,...

Trust and satisfaction are essential ingredients for successful business relationships in business-toconsumer electronic commerce. Yet there is little research on trust and satisfaction in e-commerce that takes a longitudinal approach. Drawing on three primary bodies of literature, the theory of reasoned action, the extended valence framework, and expectation-confirmation theory, this study syn...

A field study was conducted to examine if purchase behavior was systematically related with which segments of consumers who differ in their cognitive and sensory innovativeness, and instrumental and expressive expectations, respectively. Hypotheses are developed concerning the relationship with consumer innovativeness and expectations with purchase behavior, and these hypotheses were tested aga...

In this paper, we propose an efficient algorithm for PC purchase decision model of PC hardware. Many people use computers in this decade, therefore, how to purchase the PC that meets individual requirements becomes crucial. According to the results of literature review, we propose the four phases theory basis those construct the process of PC purchase decision model. The four phases are: Phase ...
