The characteristics of a world market where global competition prevails include A. a market situation where competitive conditions across national markets are linked strongly enough to form a true world market and where leading competitors typically compete head to head in many different countries. B. minor cost variations from country-to-country (as concerns production, distribution, sales and marketing, and other primary components of the industry value chain) and minimal cross- country trade restrictions. C. a competitive environment comprised of so many competitors that no company has a sizable worldwide market share. D. many companies racing for global market leadership, with most contenders using the same basic type of competitive strategy and positioned in the same strategic group. E. low barriers to entry, such as large number of rivals that the actions of any one rival have little impact on the sales and market shares of other rivals, and key success factors that vary from country to country.
