Definition
Home Bias is the tendency for consumers to spend relatively more on their own country’s products than the world average, and relatively less on the products of other countries. This phenomenon also affects investors, who tend to hold relatively more of their own country’s bonds and shares than the global average, while holding fewer foreign bonds and shares.
Historical Context
Home Bias has existed as long as cross-border trade and investment opportunities have. Historically, geographic, cultural, and informational barriers made foreign goods and investments less accessible or appealing. As transportation and communication technologies advanced, these barriers have diminished, but Home Bias persists due to a combination of factors.
Types/Categories
- Consumer Home Bias: Preference for domestic goods and services over foreign alternatives.
- Investor Home Bias: Preference for domestic stocks, bonds, and other financial instruments over foreign ones.
Key Events
- Smoot-Hawley Tariff Act (1930): An example of government policy intensifying consumer Home Bias by imposing high tariffs on foreign goods.
- Global Financial Crisis (2008): Highlighted the risks of over-reliance on domestic investments and the importance of international diversification.
