Where does share collide?

In marketing and economics, a share is a firm's or a brand's sales expressed as a fraction of the total sales in its market: it locates a competitor against the rest of the field rather than describing anything a person owns. Buzzell, Gale, and Sultan, in their 1975 study Market Share: A Key to Profitability, tracked how a business's market share moved with its return on investment across dozens of companies. The referent is a ratio of one seller's sales to the market's, measured over a period and a defined market, and it shares only the word with a unit of stock, a networked resource, or an amount given away in an experiment.[1]

Unit

A firm's or brand's sales as a fraction of total sales in a defined market

Recovery means

Measured by

Computed as a firm's sales, in units or revenue, divided by total market sales over a period

In behavioral and experimental economics, a share is the portion of an endowment that one person allocates to another, as when a proposer divides a fixed sum in a dictator or ultimatum game. Forsythe, Horowitz, Savin, and Sefton, in their 1994 study Fairness in Simple Bargaining Experiments, used these games to test whether fairness alone explains why proposers give any of the money away. The referent is an act of allocation, a behaviour recorded as the fraction of a pie handed over, and it is a different kind of thing from a unit of stock, a market ratio, or a resource on a network.[2]
