There are four types of mixed economies: welfare state capitalism, state capitalism, market socialism, and social market economy.
Welfare state capitalism involves a capitalist economy with extensive welfare and social services provided by the government. In Zambia, from 1964 to the early 1990s, there was a focus on welfare programs and social services, such as healthcare and education, to alleviate poverty and inequality.
State capitalism involves government ownership or control of key industries. In Zambia, there was a period of state capitalism in the 1970s and 1980s when industries such as copper mining were nationalized.
Market socialism combines elements of a market economy with socialist principles, such as public ownership of key industries. In Zambia, there has been a shift towards market socialism since the 1990s, with privatization and liberalization of the economy while still maintaining some government intervention in certain sectors.
Social market economy combines a market economy with a strong social welfare system. This model emphasizes social welfare, but also promotes free markets and competition. Zambia has been moving towards a social market economy since the early 2000s, with efforts to balance economic growth with social development.
The production possibility frontier is bow-shaped because of the concept of increasing opportunity costs. As an economy specializes more in the production of one good, resources must be shifted away from the production of another good, leading to a higher opportunity cost. This results in the curve of the production possibility frontier being bowed outward, reflecting the diminishing returns of resources as they are reallocated between different goods and services.
