Presumably, the majority of users consume cocaine on a quasi-controlled basis, whereas only a small fraction of consumers is likely to take advantage of available treatments [ 6].
A tiny fraction of consumers has the knowledge to discriminate among the entire range of available stereo components, and to make an informed choice based on assessments of cost and performance.
These numbers are hard to reconcile with decision costs alone; it appears that unless a sizeable fraction of consumers place large values on plan features other than cost, they are not optimizing effectively.
In a related interpretation, this fraction of consumers refers to the group of consumers that are liquidity and credit constrained or to agents that display adaptive learning behavior or other types of imperfect information; see, e.g., Milani (2009) or De Grauwe (2009).
This methodology builds on a useful feature of the theoretical model where consumers differ in their expost equilibrium behaviour - a fraction of consumers do not search, a fraction of consumers search and switch and a fraction of consumers search but refrain from switching.
To avoid this less interesting possibility, we concentrate on the case where some positive fraction of consumers do search beyond their local firm in equilibrium.
This review empirically demonstrates significant relationships between lower ACT prices and their increased availability at retail outlets, between increased ACT availability and a higher fraction of consumers who receive them, and, transitively, between lower ACT prices and their increased use.
Aside from advertising linked to search engine results, paid online ads have been less successful, with only tiny fractions of consumers actually clicking on them.
Even if 3view takes a fraction of the consumer market, winning over mind share for its brand and technology could open up all sorts of other market opportunities, says Blackwell.
However, this is only a small fraction of all consumer contracts, which include medical services as well.
