Market economy

A market economy is an economic system in which decisions about investment, production, and the distribution of goods and services to consumers are guided by price signals created through the forces of supply and demand. A key characteristic of a market economy is the presence of factor markets, which play a major role in allocating capital and other factors of production such as labor and land.

Market economies exist along a spectrum, ranging from minimally regulated to highly regulated systems. At the least regulated end are free-market and laissez-faire systems, where government involvement is largely limited to providing public goods and services and protecting private property rights.

At the other end of the spectrum are interventionist market economies, where governments take a more active role in correcting market failures and promoting social welfare. In state-directed or dirigiste systems, the government guides the broader development of the economy through tools such as industrial policies or indicative planning. In these systems, the state influences economic direction without completely replacing market-based allocation, a structure often described as a mixed economy.

Market economies are contrasted with planned economies where investment and production decisions are embodied in an integrated economy-wide economic plan. In a centrally planned economy, economic planning is the principal allocation mechanism between firms rather than markets, with the economy's means of production being owned and operated by a single organizational body.
