TRADE BARRIER: A restriction, invariably by government, that prevents free trade among countries. The more popular trade restrictions are tariffs, import quotas, and assorted nontariff barriers. An occasional embargo will be even thrown into this mix. The primary use of trade barriers is to restrict imports from entering in country. By restring imports, domestic producers of the restricted goods are protected from competition and are even subsidized through higher prices. Consumers, though, get the short end of this stick with higher prices and a limited choice of goods. In that producers tend to have more political clout than consumers, it's pretty obvious why trade barriers are a "natural" state of affairs.

    Aggregate Demand

    This lesson introduces aggregate demand, the demand-side of the aggregate market. The aggregate market is the key model used to explain and analyze the workings of the macroeconomy and aggregate demand is a critical half of this model (the other is aggregate supply). Taking a clue from market demand, this lesson examines the nature of aggregate demand, including the relation between the price level and aggregate expenditures, the reason the aggregate demand curve is negatively sloped, and the assorted aggregate demand determinants that cause the aggregate demand curve to shift.

    • The first unit of this lesson introduces the concept of aggregate demand and how it fits into the study of macroeconomics in terms of the aggregate market and circular flow.
    • In the second unit, we example the four aggregate expenditures -- consumption, investment, government purchases, and net exports -- the make up aggregate demand.
    • The third unit then examines the aggregate demand curve that captures the aggregate demand relation between the price level and aggregate expenditures, especially the importance of the real-balance, interest-rate, and net-export effects.
    • A look at the assorted aggregate demand determinants that shift the aggregate demand curves is the topic of the fourth lesson.
    • We end this lesson in the fifth unit with a look how demand-management policies work to stabilize business cycles through aggregate demand.

    A social science that studies the allocation of limited resources used to produce the goods and services that satisfy unlimited consumer wants and needs. Economics is one of several social sciences (others are sociology, political science, and anthropology) which applies the scientific method to human behavior. The distinguishing feature of economics is a concern with the fundamental problem of scarcity--unlimited wants and needs and limited resources. Economics is commonly divided into two branches--macroeconomics and microeconomics.
