Disposable income is the most impor

Disposable income is the most important economic attribute that creates distance between countries. Rich countries engage in proportionately higher levels of cross-border economic activity than poorer ones. The greater the economic distance between a company’s home country and the host country, the greater the likelihood that it must make significant adaptations to its business model. Wal-Mart in India, for instance, would be a very different business from Wal-Mart in the United States. But Wal-Mart in Canada is virtually a carbon copy of the U.S. Wal-Mart. An exception to the distance rule is provided by industries in which competitive advantage is derived from economic arbitrage, that is, the exploitation of cost and price differentials between markets. Companies in industries whose major cost components vary widely across countries, like the garment and footwear industries, where labor costs are important, are particularly likely to target countries with different economic profiles for investment or trade. Whether or not they expand abroad for purposes of replication or arbitrage, all companies find that major disparities
in supply chains and distribution channels are significant barriers to business. This suggests that focusing on a limited number of geographies may prove advantageous because of reduced operational complexity. This is evident in the home-appliance business, for instance, where companies—like Maytag—that concentrate on a limited number of geographies produce far better returns for investors than companies like Electrolux and Whirlpool, whose geographic spread has come at the expense of simplicity and profitability.
