CHANGE IN AGGREGATE DEMAND: A shift of the aggregate demand curve caused by a change in one of the aggregate demand determinants. In essence, a change in aggregate demand is caused by any factor affecting aggregate demand EXCEPT the price level. This concept should be contrasted directly with a change in aggregate expenditures. You might also want to review the terms change in quantity demanded and change in demand, as well. The change in aggregate demand is comparable to the change in market demand. A change in aggregate demand is a change in ALL price level-aggregate expenditure combinations, meaning that each price level is matched up with a different aggregate expenditure (which is illustrated as a shift of the aggregate demand curve). This change in aggregate demand is caused by a change in any of the aggregate demand determinants. In contrast, a change in aggregate expenditures is a change from one price level-aggregate expenditure combination to the another (which is illustrated as a movement along a given aggregate demand curve).

SOCIALISM:

In theory, an economy, or economic system, that is a transition between capitalism and communism and is based on: (1) government, rather than individual, ownership of resources, (2) worker control of the government, such that workers, rather than capitalist, control capital and other productive resources, (3) income allocated on need rather than on resource ownership or contribution to production. In practice, socialism is a type of economy based on--(1) government ownership and control of the most crucial resources, like those for energy production, communication, transportation, and health care and (2) a heavy dose of central planning by government.
Although socialism represents the theoretical transition from capitalism to communism, the primary goals of modern real world socialism are: (1) to correct the inefficiencies of market failures, (2) to obtain more equal wealth and income distributions, and (3) to equalize economic opportunities. To accomplish these goals, government exerts a significant amount of government control, while less than communism, more than capitalism.

Perhaps more so than other economic systems, socialism comes in many different varieties. Some nations practice a form of socialism that comes very close to communism, with extensive government control. Socialism found in other nations has a distinctive capitalistic flavor, with a great deal of market activity.

Government Ownership and Control

A distinguishing characteristic of socialism is government ownership and control over key industries and resources. Government ownership and control generally begins with transportation, energy, and communication. Socialist governments generally view these industries and their associated resources as the ones most likely abused by private ownership.

More active socialist governments tend to exert greater control over other industries, such as health care, heavy manufacturing (such as steel production), and agricultural production. In the extreme, everything is owned and controlled by government, resulting in communism.

Central Planning

Government ownership of resources and control of industries under socialism necessitates control of allocation decisions. This is often accomplished through central planning. While less extensive than found in communism, detailed plans are needed to allocate resources in the absence of market exchanges. And while such planning generally lacks the efficiency incentives found in markets, it can improve the efficiency if the markets would otherwise fall victim to failures.

For example, transportation systems are usually owned and controlled by governments under socialism due to the possible market failure of market control, especially the emergence of natural monopoly.

A Mixed Economy

Socialism occupies a large section of the spectrum of economic systems, bounded by a pure market economy on one end and a pure command economy on the other. Socialism tends to lay closer to the pure command economy of the spectrum, but it can also edge toward the pure market economy side dominated by capitalism.

Socialism, like all other real world economic systems, is thus a mixed economy. Allocation decisions are undertaken by both governments and markets. Some socialistic nations rely more on governments and less on markets, while others rely a little more on markets and a little less on governments. But all rely on both to some degree.

The Politics of Socialism

The concept of socialism dates back almost to the beginnings of philosophical thought into the human prospect. Socialistic principles, for example, can be found in the works of Plato and the New Testament of the Christian Bible.

Over the centuries socialism has been as closely aligned with political thinking as with economic analysis. It has formed the foundation of numerous political parties and helped inspire scores of revolutions. On the spectrum of political thinking, socialism is more likely embraced by liberals and the political left than by conservatives and the political right.
