a$.$ in globally competitive industries, a company's competitive position in one country both affects and is affected by its position in other countries.

b$.$ in global competition, rivals vie for worldwide market leadership and the leading competitors compete head$-$to$-$head in the markets of many different countries.

c$.$ in multidomestic competition, there is greater cross$-$country variation in market conditions and the nature of the competitive contest among rivals than tends to be the case in globally competitive markets.

d$.$ with multidomestic competition, the competitive contest is localized, with rivals battling for national market leadership; moreover, winning in one country market does not necessarily signal that a company has the ability to fare well in the markets of other countries.

e$.$ in global competition, the size of a firm's worldwide competitive advantage $($or disadvantage$)$ equals the sum of the competitive advantages $($or disadvantages$)$ it has in each country market where it competes.
