Forms of Governments

Types of Government are based on one key question: Who governs and what is the citizen participation ? We will only be discussing three types of government: Democracy, Monarchy, Communism

Democracy In a democracy, the government is elected by the people. Everyone who is eligible to vote has a chance to have their say over who runs the country. It is distinct from governments controlled by a particular social class or group (aristocracy; oligarchy) or by a single person (despotism; dictatorship; monarchy). A democracy is determined either directly or through elected representatives.

Monarchy A monarchy has a king, queen, emperor or empress. The ruling position can be passed on to the ruler’s heirs. In some traditional monarchies, the monarch has absolute power. But a constitutional monarchy, like the UK, also has a democratic government that limits the monarch's control.

Communism In a communist country, the government owns property such as businesses and farms. It provides its people's healthcare, education and welfare.

Traditional Economy Traditional Economy - is a system in which the allocation of resources and other economic activities are affected by ritual, custom, or habit. Example: The Tuareg of the Sahara in northern Africa are nomadic herders who travel about the region in search of food and water for their animals. They produce most of the things they need and trade with others for what they need and cannot produce.

Command Economy Command Economy - is a system organized around a central authority which makes most of the major economic decisions. The government decides what products are made, how much is produced, and what the goods cost. Example: Cuba’s economy

Cuba’s Command Economy Most of the means of production are owned and run by the government and most of the labor force is employed by the state. In the year 2000, the public sector employment was 76% and the private sector at 23%. The Cuban government sets most prices and rations goods to citizens.

Market Economy Market Economy – individuals depend on supply, demand, and prices to determine the answers to the four economic questions of "what to produce," "how to produce," "how much to produce," and "for whom to produce.” In a market economy, most businesses are privately owned. When a company sells its products, it earns a profit. Owners decide how to use profits and how much to pay workers. Why would consumers be important to a market economy?
