The primary difference lies in ownership: market economies are characterized by private ownership of the means of production and decentralized decision-making, while command economies feature state or public ownership and centralized planning.

The informal economy encompasses all economic activities that are not regulated, taxed, or monitored by the government. This includes a wide range of activities, from street vending and day labor to domestic work and home-based production. Because these transactions occur outside the formal legal and institutional framework, they are often excluded from official GDP calculations. Understanding the informal economy is essential for analyzing labor markets, poverty, and the survival strategies of marginalized populations in both developing and developed nations.

Gross National Income (GNI) is a standard economic metric used to measure the total domestic and foreign output claimed by residents of a country. It is a vital tool in sociology for analyzing global stratification, poverty levels, and the economic development of nations.

Adam Smith, an 18th-century Scottish philosopher and economist, is famously associated with the concept of laissez-faire, which advocates for minimal government interference in economic affairs. In his seminal work, 'The Wealth of Nations,' Smith argued that individual self-interest and competition in a free market naturally lead to economic prosperity and social benefit, a mechanism he famously described as the 'invisible hand.' His theories laid the groundwork for classical liberal economic thought.

Transnational corporations (TNCs) play a dominant role in the global economy. Estimates suggest that approximately two-thirds of international trade is either directly conducted by TNCs or involves their subsidiaries and supply chains, highlighting their significant influence on global economic integration and market dynamics.

In a market economy, the law of supply and demand dictates that when the demand for a product is higher than the available supply (a shortage), the price typically increases as consumers compete for the limited goods available.
