SCARCE GOOD: A resource with an available quantity less than its desired use. Scarce resources are also called factors of production. Scarce goods are also termed economic goods. Scarce resources are used to produce scarce goods. Like the more general society-wide condition of scarcity, a given resource is scarce because it has a limited availability in combination with a greater (potentially unlimited) productive use. It's both of these that make it scarce. In other words, even though an item is quite limited it will not be a scarce resource if it has few if any uses (think pocket lint and free good).

Lesson 8: Market Shocks | Unit 3: Single Shifts Page: 12 of 20

Topic: Summary <=PAGE BACK | PAGE NEXT=>

  • The four basic changes in the market caused by increases or decrease in demand or supply.
  • The six steps sequence to analyze any market shock: (1) a determinant changes, (2) a curve to shifts, (3) a shortage or a surplus occurs, (4) the price changes, (5) the quantities demanded and supplied change, and (6) the market imbalance is eliminated and equilibrium is restored.
  • That an increase in demand causes an increase quantity and an increase in price.
  • That a decrease in demand causes a decrease quantity and a decrease in price.
  • That an increase in supply causes an increase quantity and a decrease in price.
  • That a decrease in supply causes a decrease quantity and an increase in price.

AGGREGATE DEMAND CURVE

A graphical representation of the relation between aggregate expenditures on real production and the price level, holding all ceteris paribus aggregate demand determinants constant. The aggregate demand (AD) curve is one side of the graphical presentation of the aggregate market. The other side is occupied by the long-run aggregate supply curve and/or the short-run aggregate supply curve. The negative slope of the aggregate demand curve captures the inverse relation between aggregate expenditures on real production and the price level. This negative slope is attributable to the interest-rate, real-balance, and net-export effects.

This isn't me! What am I?

Potato chips were invented in 1853 by a irritated chef repeatedly seeking to appease the hard to please Cornelius Vanderbilt who demanded french fried potatoes that were thinner and crisper than normal.
"Whatever course you decide upon, there is always someone to tell you that you are wrong. There are always difficulties arising which tempt you to believe that your critics are right. To map out a course of action and follow it to an end requires...courage."

-- Ralph Waldo Emerson
