Semi-continuous data comes from a distribution that is mixture of the point mass at zero and continuous with support on positive real line. Such appear in several real-life situations like blind signal separation problems, modeling loss finance insurance, sales consumer goods, daily precipitation data, to name few. In this paper, we present novel algorithm estimate density function for semi-con...

Multi-store ...rms are common in the retailing industry. Theory suggests that cross-elasticities between stores of the same ...rm enhance market power. To evaluate the importance of this e¤ect in the UK supermarket industry, we estimate a model of consumer choice and expenditure using three data sources: pro...t margins for each chain, a survey of consumer choices, and a data set of store chara...

Consumers value keeping some information about them private from potential marketers. E-commerce dramatically increases the potential for marketers to accumulate otherwise private information about potential customers. Online marketers claim that this information enables them to better market their products. Policy makers are currently drafting rules to regulate the way in which these marketers...

We estimate a random utility model of demand to measure consumer response to package downsizing in consumer goods markets. To our knowledge this paper provides the first estimates of consumer response to package size. We perform the analysis using Nielsen Homescan data on bulk ice cream purchases of a panel of households in Chicago, between 1998 and 2007. The estimation framework involves model...

I today’s multibrand, multichannel marketplace, optimal channel design involves issues such as distribution intensity, channel exclusivity, vertical and horizontal coordination, and online–offline mixed structures. We investigate how a firm’s choice in these design issues affects its profitability under varying levels of brand and outlet differentiation. Our spatial model explicitly captures he...

People actively attempt to create and maintain positive moods and to escape from negative moods by engaging in various consumption activities. The principle of homeostasis explains the essence of this mood-management behavior: that consumers adjust their mood and activities to preserve constant the conditions of life. We model the dynamics of consumer mood and mood-management behavior through a...

This work carries out a hedonic price analysis in the Italian grappa market. We use a dataset composed of around 15.576 observations of retail chain prices (related to transactions taken place in Italy in the period 1997-2004) and product characteristics. We estimate the implicit price of the main product attributes. Results show that particularly bottle format, high alcohol content and brand a...

Online consumers must burrow through vast piles of product information to find the best match to their preferences. This has boosted the popularity of recommendation agents promising to decrease consumers' search costs. Most recent work has focused on refining methods to find the best products for a consumer. The question of how many of these products the consumer actually wants to see, however...

The objective of this study has been to develop a typical specification of the Almost Ideal Demand System (AIDS) for Iran’s composition of imports including capital, intermediate and consumer goods. Accordingly, we first test the hypotheses that import demand is homothetic, homogeneous, symmetric, and depends on domestic prices. Then, we estimate the long-run elasticities of the composition o...
