In this work, we consider a utility function that is influenced by the value of network externality function at the consumer’s expected market size/share. Using this utility function, a market share adjustment function is introduced and is utilized to develop dynamic models of existing rational and static expectation processes. In addition, the role and scope of dynamic models of market share a...

The study aimed at analyzing the structure, conduct and performance of fish market in Lake Zeway, Central part of Ethiopia. A total of 24 traders from 6 markets were selected for the study purposively. Data analysis was carried out using descriptive statistics, for Structure, Conduct and Performance (SCP) approach. According to the results, there were five kinds of fish marketing chains in the ...

We characterize the evolution of market share when agents freely observe past shares and also engage in costly private learning. We show that popular options may remain unchosen. Even among chosen goods, long run market shares skew toward ex ante popular items. This rationalizes market share policies that encourage experimentation. We show that an outside observer with rich data may be better a...

This paper presents an empirical assessment of movie theatre attendance in two major metropolitan markets and provides strong support for the importance of spatial characteristics in determining attendance. We consider the hypothesis that attendance at a particular movie theatre reflects a tension between two effects: a negative competition effect and a positive agglomeration effect. We find ev...

Abs t r ac t . We propose the share-confidence framework for knowledge discovery from databases which addresses the problem of mining itemsets from market basket data. Our goal is two-fold: (1) to present new itemset measures which are practical and useful alternatives to the commonly used support measure; (2) to not only discover the buying patterns of customers, but also to discover customer ...

In this paper we demonstrate how the global dynamics of an economic model can be analyzed. In particular, as an application, we consider a market share attraction model widely used in the analysis of interbrand competition in marketing theory. We analyze the local and global dynamic properties of the resulting two-dimensional noninvertible dynamical system in discrete time. The main result of t...

Data-acquisition involves gathering signals from measurement sources and digitizing the signal for storage, analysis and presentation on a PC. Analysis and prediction is very necessary in today’s market for the accurate utilization of funds at hand. For analysis, there has to a proper system where in the required data is first acquired from the destination. This data then needs to be analysed u...

We develop a consumer-level model of vehicle choice to shed light on the erosion of the U.S. automobile manufacturers’ market share during the past decade. We examine the influence of vehicle attributes, brand loyalty, product line characteristics, and dealerships. We find that nearly all of the loss in market share for U.S. manufacturers can be explained by changes in basic vehicle attributes,...

I explore the effects of on-net / off-net differentiation on network sizes in mobile telecommunications when both rational and non-rational consumers coexist in the market. In particular, three different types of consumers are modeled: (1) fully informed rational (FIR) consumers who are perfectly informed about the true market shares of all networks and choose the network with the lowest expect...
