The problem with these descriptions, however, is that very few economic systems stick to one school of thought. Enter mixed economies, which combine a free market ethos with a socialist-shaped safety net. As a general rule, government intervention in mixed economies is present but falls short of deciding the goods and services that will be produced, how they will be produced, who will produce them, and how much people will pay for them. Instead, the government's primary role is to ensure some degree of social welfare is maintained.
Upsides and downsides of mixed economies
There are advantages and disadvantages to a mixed economy. Among the advantages:
- Resources are allocated more efficiently in a mixed economy, resulting in customer satisfaction. Consider, for example, the former Soviet Union (Union of Soviet Socialist Republics). The country prioritized military spending over consumer goods, eventually leading to unrest that caused its collapse when its leaders attempted to loosen political and economic control of its republics and satellite states.
- Innovation is rewarded, providing producers with greater profits. Consider Apple (AAPL -0.36%), for example, which has been the most valuable company in the world by market capitalization. The company has been valued at more than $3 trillion, largely on the strength of innovations such as the iPhone, iPad, and Apple Watch.
- Governments are able to raise revenues to cover the costs of less-profitable ventures, such as defense, education, and transportation. Although some segments may be wildly profitable, such as military contracting services, it's unlikely that any country could defend itself from external threats with private armies.
Disadvantages of mixed economies include:
- Potential lack of incentives for efficient production if government support is overemphasized. The cost of a college education in the United States has soared over the past decades, in part due to government programs that created a massive student loan market.
- Moral hazards created by large businesses that are aware governments won't let them fail. During the 2007-09 global financial crisis, for example, critics argued that banks weren't concerned about becoming overextended during a housing bubble since they knew the federal government would stage a bailout if necessary.
