Q

What is the crowding out effect?

A
  • Increase in government borrowing, leads to increase in int. rates, firms then reduce spending and borrowing as a result. This decreases the impact of aggregate demand of deficit spending.
  • Known as crowding out b/c gov. borrowing takes place of private borrowing.

    1. What is an import license?
  2. What is a tariff?
  3. What is an export subsidy?
  4. What is a voluntary export restraint
A
  1. limit on amnt imported.
    1. right to export to domestic country. Gov. can sell these.
  2. tax on imported good collected by gov.
  3. Gov pymnt to firm that export goods.
  4. Country voluntary limits amount of a good exported. Often in hope of avoiding tariff or quotas imposed by trading partner.
  • case of quota, if gov gets full value of import license, result =same as tariff.

Q

What is a recessionary Gap?

What are good/bad investments during this time?

A
  • excess supply. Business will see build up inventory and decrease P and Q and result.
  • Long term bonds and commodities are good investments
    • int. rates will decrease. So long term bonds P will increase.
    • Commodities will decrease in p. so bad.

Q

real exchange rate (d/f) =?

A
  • nominal exchange rate (d/f) * (CPI f/CPI d)
  • Ex: At a base period, the CPis ofthe U.S. and U.K. are both 100, and the exchange rate is $ 1 .70/£. Three years later, the exchange rate is $ 1 .60/£, and the CPI has risen to 1 1 0 in the United States and 1 1 2 in the U.K. What is the real exchange rate?
  • A: 1.60* (112/110) = $1.629

Q

No arbitrage relation, int. rate parity =?

A

Forward/Spot = (1+ int. ratedomestic) /(1+int. rateforeign)

  • If spot and int expressed as domestic/foreign, then domestic int. rate goes in numerator on right hand side of eqn. If given as foreign/domestic, then foreign goes in numerator in right side.
  • Ex: Consider two currencies, the ABE and the DUB. The spot ABE/DUB exchange rate is 4.5671, the 1-year riskless ABE rate is 5o/o, and the 1-year riskless DUB rate is 3o/o. What is the forward exchange rate that will prevent arbitrage profits?

Answer:

Rearranging our formula, we have:

forward = spot [1 +IABE] and we can calculate the forward rate as l +Ious

forward=4.5671 (1.05)=4.6558(AB%uB) 1.03

Note that the forward rate is greater than the spot rate by 4.65 58 I 4.5671 - 1 = 1 .94%. This is approximately equal to the interest rate differential of 5o/o - 3o/o = 2o/o. The currency with the higher interest rate should depreciate over time by approximately the amount o f the interest rate differential.

37
Q

Neoclassical Economics

A
  • Shifts in aggregate supply/demand are primarily driven by changes in technology.
  • Economies have a strong tendency toward full-employment equilibrium.
  • Recessions put downward pressure on the money wage rate.
  • Over-full employment puts upward pressure on the money wage rate.
  • Business cycles are temporary deviations from long-run equilibrium.
38
Q

Keynesian Economics

A
  • Wages and prices of productive inputs (other than labor) are “downward sticky”.
  • Use monetary and fiscal policy to increase aggregate demand.
39
Q

Monetarist Economics

A
  • Variations of aggregate demand are caused by inappropriate decisions made by monetary authorities.
  • Recessions can be created by inappropriate decreases in the money supply or external shocks.
  • Central bank should increase the money supply steadily and predictably.
40
Q

Austrian Economics

A
  • Business cycles are caused by government intervention in the economy.
41
Q

New Classical Economics

A
  • Real Business Cycle Theory (RBC)
  • Emphasizes effect of real economic variables such as changes in technology and external shocks.
  • Applies Utility Theory to Macroeconomics.
  • Individuals and firms maximize utility.
  • Policymakers should not try to counteract business cycles.
42
Q

Frictional Unemployment

A

The time lag necessary to match employees who seek work with employers needing their skills.

43
Q

Structural Unemployment

A

Caused by long run changes in the economy that eliminate some jobs while creating others for which unemployed workers are not qualified.

44
Q

Cyclical Unemployment

A

Caused by changes in the general level of economic activity. Positive when the economy is operating at less than full capacity and can be negative when employment is over the full employment level.

45
Q

second price sealed bid auction

vickrey auction

A

bidder submitting highest bid wins item and pays amount bid by second highest bidder.

46
Q

descending price auction

dutch auction

A
  • begins with highest price anyone willing to pay, and price reduced until bidder agrees to pay it.
  • If many units, then each bidder specifies how many units they want and offer price reduced until a bidder agrees to pay it.
  • modified dutch auction - winnig bidders pay same price which is reservation price of bidder whose bid wins the last units offerred.

47
Q

taxes

subsidies

quotas

A

INCREASE PRICE BUYER PAYS, and decrease amount sellers recieve

increase amount sellers receive and decrease the price buyers pay, leading to production of more than efficient quantity of good.

government imposed production limits, resulting in production of less than efficient quantity of good.

48
Q

external costs

A

costs imposed on others by the production of goods which are not taken into account in the production decision.

ex- costs associated with fisherman polluting ocean while fishing.

49
Q

statutory incidence

A
  • who is legally responsible for paying the tax.
50
Q

Price elasticity

A
  • measure of responsiveness of quantity demanded to a change in price.
  • %►Qd/%►P
  • when quantity demanded is responsive to change in price - elastic
  • when quantity demanded not responsive we say - inelastic
  • unitary elasticity % change in price = % change in quantity so change in price will not effect total revenue.
51
Q

income elasticity of demand

A
  • sensitivity of quantity demanded to change in income.
