INTRODUCTION: More than two decades after the initiation of agricultural market reforms in eastern and southern Africa (ESA), governments in the region are increasingly using parastatal grain marketing boards (GMBs) and/or strategic grain reserves (SGRs) to directly influence the prices faced by farmers and consumers (Jayne Chapoto, and Govereh 2007). In Zambia, the government through the Food ...

Research on materialism has burgeoned in the last two decades, yet little is known about how people higher versus lower in this consumer values orientation differ in their dayto-day spending habits and in their emotional reactions to spending on purchases. The present study used an event-sampling method over a 3-week period to address these questions in a community adult sample. Results showed ...

We develop a behavioral axiomatic characterization of Subjective Expected Utility (SEU) under risk aversion. Given is an individual agent’s behavior in the market: assume a finite collection of asset purchases with corresponding prices. We show that such behavior satisfies a “revealed preference axiom” if and only if there exists a SEU model (a subjective probability over states and a concave u...

With the advent of e-commerce, opportunities have arisen for students to obtain course textbooks from sources other than the traditional campus bookstore(s). This research seeks to understand the factors motivating students to select e-commerce or traditional vendors for their textbook purchases. It surveys student perceptions of e-commerce textbook purchases from the perspectives of product pe...

Storable products allow consumers to time their purchases to exploit price fluctuations. It has been documented that during promotions consumers buy more. The additional purchases are potentially intended not only for current use, but to be stockpiled for future consumption. This paper discusses the predictions of a consumer inventory model and reviews the available evidence. We then discuss th...

Despite the intensifying debate over the taxation of Internet commerce, the relevant issues have not been given a systematic treatment in the context of the literature on optimal taxation. This article presents such an analysis and investigates separately the taxation of business purchases of intermediate goods, the taxation of consumer purchases of final goods and services, and the various iss...

When one field is used to define the observational unit in a dataset, it becomes difficult to alter the dataset to define a different observational unit. For example, customer drug purchases are usually defined by the purchase rather than by the customer. The Association Node in Enterprise Miner uses a customer identifier to link purchases when the purchase is the observational unit. However, t...

We show how third-party web trackers can deanonymize users of cryptocurrencies. We present two distinct but complementary attacks. On most shopping websites, third party trackers receive information about user purchases for purposes of advertising and analytics. We show that, if the user pays using a cryptocurrency, trackers typically possess enough information about the purchase to uniquely id...

Growth in the number of food products and brands carried by grocery stores implies a preference for diversity. We examine the factors that affect the variety of food purchases across U.S. markets. Three measures of variety, based on market-level sales of both grocery categories and RTE cereal brands, are regressed on various population and market characteristics. We find that markets with a hig...
