who is primarily responsible for making economic decisions in a market economy
Market economy A market economy is an economic system in which the decisions regarding investment, production, and distribution are guided by the price signals created by the forces of supply and demand. The major characteristic of a market economy is the existence of factor markets that play a dominant role in the allocation of capital and the factors of production.[1][2]
Supply-side economics Supply-side economics is a macroeconomic theory that argues economic growth can be most effectively created by lowering taxes and decreasing regulation.[1][2] According to supply-side economics, consumers will then benefit from a greater supply of goods and services at lower prices and employment will increase.[3] It was started by economist Robert Mundell during the Ronald Reagan administration.
