Q

List the direct relationship factors to shift demand curve upwards other than price

A
  • Price of substitute goods (Inc in P of hamburgers will inc demand for hot dogs)
  • Expectations of price change (tax in the future, buy more now)
  • Income for normal goods (as wealth inc, demand inc)
  • Extent of the market (more babies=more baby food demand)

Q

List the inverse relationship factors that shift demand curve downward

A
  • Price of a complement good (Inc in P of chips will cause less demand for salsa)
  • Income for inferior goods (when wealth inc, demand for used cars decreases)
  • Consumer boycott
  • Consumer tastes change
  • Contraction (less spending decreases equilibrium GDP)

Q

Explain effects when supply shifts to the right

A

Sellers will now supply more quantity at the same or lower price (At $20, now supply 70 instead of 50 units; for a quantity of 50, now charge lower price of $10 instead of $20)

A

Savings / Income

69
Q

Reducing the rate of monetary growth…

A

makes less money available, increasing interest rates as people compete for loans.

70
Q

government borrowing to finance large deficits has which of the following effects?

A

exert upward pressure on interest rates. With more demand and a supply that stays static or increases less than the increase in demand, the price increases

71
Q

To maintain a fixed exchange rate, a country may have to do all of the following

A
  1. Change its interest rates to match changes in the country whose currency it targets.
  2. Increase its interest rates if it has a higher inflation rate than the country whose currency it targets
  3. Increase its interest rates if it has a trade deficit with the country whose currency it targets
72
Q

Exchange rate influences

A

One currency will depreciate relative to another at a rate equivalent to the difference in their inflation rates

73
Q

Explain cyclical vs counter-cyclical businesses

A

Businesses or industries that perform much better than average during expansions and much worse than average during recessions are called cyclical; businesses or industry that that perform better during recessionary phases and worse during expansionary phases are called counter-cyclical or defensive (Replacement auto part industry = counter-cyclical)

74
Q

The labor market for masons is competitive and stable. What is the likely short-term result of an attempt to increase masons’ wages?

A

Decreased employment levels

75
Q

Comparative Advantage

A

Exists when the OC of producing that good is less than the cost of producing other goods in the same country, compared to another country.
- Whoever has lower OC should produce (when trying to find OC it goes on the bottom of the fraction)

76
Q

What is the primary reason for nations to devalue their currencies?

A

Improve the balance of trade- currency devaluation:

  1. Makes exports cheaper in foreign markets, increasing exports.
  2. Increase domestic inflation (money is worth less than it was before devaluation)
  3. Reduce foreign investment, as prices for foreign goods and investments become higher priced (in terms of local currency).
77
Q

Assumptions of Classical Economic Theory

A
  1. Full employment is an attribute of equilibrium
  2. Flexible wages allow self-correction of shortages and surpluses in labor markets
  3. Increase in money leads to an increase in aggregate demand
78
Q

What group would an import tariff on cars benefit most?

A

Import tariffs result in higher costs for the consumer of the imported product and, hence, lower quantity demanded

79
Q

What is the effect on prices of U.S. imports and exports when the dollar depreciates?

A

Import prices will increase and export prices will decrease (imports increase bc foreign sellers want more of the devalued currency; exports decrease bc nation’s goods are cheaper to foreign purchasers)

80
Q

Diminishing Returns

A

There is a point at which equal additional units of input add less to the output than previous units of input (decreasing efficiency)

81
Q

Lower inflation leads currencies to

A

Appreciate

82
Q

Increases in interest rates cause…

A

a country’s currency to appreciate because higher interest rates provide higher rates to lenders, thereby attracting more foreign capital, which causes a rise in exchange rates

85
Q

How can a company manage the risk of raising interest rates in the future

A
  • Replace LT bonds with ST bonds like high yields or floating rate bonds
  • Sell LT bonds, promote LT CD’s
  • Derivative swaps (interest rate futures, but fees will increase with rates)
  • Reduce mismatch between average maturities of its A and L (bc of mismatch interest exp will increase faster than interest income)
86
Q

When economy-wide interest rates climb substantially…

A
  1. In the short term, banks with many variable-rate loans perform better than banks with many fixed-rate loans
  2. Long-term loans will reprice to higher interest rates more slowly than short-term loans
