ADJUSTMENT, LONG-RUN AGGREGATE MARKET: Disequilibrium in the long-run aggregate market induces changes in the price level that restore equilibrium. If the price level is above the long-run equilibrium price level, economy-wide product market surpluses cause the price level to fall. If the price level is below the long-run equilibrium price level, economy-wide product market shortages cause the price level to rise. In both cases long-run equilibrium is restored. Price level changes induce changes in aggregate expenditures but NOT changes in real production. The reason is that long-run aggregate supply is full-employment real production, which is unaffected by the price level.

Demand
This lesson on demand offers a little insight into the purchases of a wide range of goods. In fact, this demand topic is does more than offer insight into buying behavior. It's also one half of the market analysis -- the other half being supply. And market analysis is one of the most widely used tools in the study of economics. Economists explain a lot of economic phenomenon using markets. But to use markets, we need demand. And that brings us back to this lesson. - In the first unit of this lesson we examine the basic concept of demand. While you've likely come across the term demand before, we'll see the specific way the term is used in economics.
- The second unit then takes a look at the law of demand, which is one of the most important and most fundamental economic principles that we'll encounter.
- As we more on to the third unit, our attention turns to the demand curve, which is the graphical embodiment of the demand concept.
- In the fourth unit, we examine how the five basic demand determinants cause the demand curve to shift from one location to another.
- And finally in the fifth unit, we make a connection between demand and the fundamental problem of scarcity.

ALTERNATIVE UNEMPLOYMENT RATES The official unemployment rate estimated and reported monthly by the Bureau of Labor Statistics (BLS) using data from Current Population Survey is one of six alternative measures of unemployment tracked and reported by the BLS, officially labeled sequentially U1 through U6. The "official" unemployment rate is U3. The other five measures seek to document different ways in which labor can be under utilized, including unemployment duration, job losers, discouraged workers, marginal workers, and part-time workers.
