ECON MACRO TEST 2

Based on the growth accounting​ equation, equal percentage increases in capital and labor will leave output per worker unaffected only if ak+an =

1

Higher saving rate means

higher capital-labor ratio, higher output per worker, and higher consumption per worker

Time to maturity - Because long-term interest rates usually exceed short-term interest rates,

a risk premium exists: the compensation to an investor for bearing the risk of holding a long-term bond

Which of the following best completes the definition of money as used by​ economists?

a special set of assets that are widely accepted as payments for goods and services.

During the period​ 1973-1975, the United States experienced a deep recession with a simultaneous sharp rise in the price level. Would you conclude that the recession was the result of a supply shock or a demand​ shock?

a supply​ shock, because if it was a demand​ shock, the price level would have declined

Endogenous growth theory attempts to

explain, rather than assume, the economy's growth rate - The growth rate depends on many things, such as the saving rate, that can be affected by government policies

An increase in population growth rate, n, causes long run output, consumption, and capital per worker to

fall more output must be used to equip new workers with capital leaving less output available for consumption or to increase capital per worker

In the quantity theory of​ money, velocity is assumed to be highly

stable

US has had ___ recessions usually lasting___ months

11 10.2

What is​ comovement?

Macroeconomic variables that tend to move in the same direction over time.

How is the price level related to nominal money​ demand?

They are directly related- the higher the price​ level, the higher the demand for money.

money has ____ risk level, return, and time to maturity

lowest

Asset market equilibrium—an aggregation assumption

- Assume that all assets can be grouped into two categories, money and nonmonetary assets • Money includes currency and checking accounts - Pays interest rate im - Supply is fixed at M • Nonmonetary assets include stocks, bonds, land, etc. - Pays interest rate i = r + πe - Supply is fixed at NM

Problems with the leading indicators

- Data are available promptly, but often revised later, so the index may give misleading signals - The index has given a number of false warnings - The index provides little information on the timing of the recession or its severity - Structural changes in the economy necessitate periodic revision of the index Research by Diebold and Rudebusch showed that the index does not help forecast industrial production in real time - In real time, the index sometimes gave no warning of recessions

• Should a policy goal be to reduce population growth?

- Doing so will raise consumption per worker - But it will reduce total output and consumption, affecting a nation's ability to defend itself or influence world events

Basic assumptions and variables of Solow Model

- Population and work force grow at same rate n - Economy is closed and G = 0

• In equilibrium, productivity improvement increases the capital-labor ratio, output per worker, and consumption per worker

- Productivity improvement directly improves the amount that can be produced at any capital-labor ratio - The increase in output per worker increases the supply of saving, causing the long-run capital-labor ratio to rise

The business cycle is _______, but not _______

- Recurrent means the pattern of contraction- trough-expansion-peak occurs again and again - Not being periodic means that it doesn't occur at regular, predictable intervals

The fundamental determinants of long-run living standards

- The saving rate - Population growth - Productivity growth

Velocity and the quantity theory of money

- Velocity (V) measures how much money "turns over" each period V = nominal GDP / nominal money stock = PY / M

Other factors affecting money demand

- Wealth: A rise in wealth may increase money demand, but not by much - Risk • Increased riskiness in the economy may increase money demand Liquidity of alternative assets: Deregulation, competition, and innovation have given other assets more liquidity, reducing the demand for money - Payment technologies: Credit cards, ATMs, and other financial innovations reduce money demand

Money demand affected by

-price level -real income -interest rates

Burns and Mitchell (Measuring Business Cycles, 1946) makes five main points about business cycles:

1. Business cycles are fluctuations of aggregate economic activity, not a specific variable 2. There are expansions and contractions 3. Economic variables show comovement—they have regular and predictable patterns of behavior over the course of the business cycle 4. The business cycle is recurrent, but not periodic 5. The business cycle is persistent

leading, lagging, or coincident 1. business fixed investment 2. residential investment 3. inventory investment 4. stock prices 5. money supply 6. nominal interest rates

All else being​ equal, how would each of the following affect the demand for M1​? For M2​? 1. The maximum number of checks per month that can be written on money market mutual funds​ (MMMFs) and money market deposit accounts is raised from three to thirty. 2. Home equity lines of credit that allow homeowners to write checks against the value of their homes are introduced. 3. The stock market​ crashes, and further sharp declines in the market are widely feared. 4. Banks introduce overdraft​ protection, under which funds are automatically transferred from savings to checking as needed to cover checks. 5. A crackdown reduces the illegal drug trade​ (which is carried out largely in​ currency).

Cash; Savings​ Account; U.S. Savings​ Bond; Land

- The M2 monetary aggregate

M2 = M1 + less money like assets - Additional assets in M2: • savings deposits • small (< $100,000) time deposits • non-institutional MMMF balances • money-market deposit accounts (MMDAs)

Endogenous growth theory has constant

MPK Increases in capital and output generate increased technical knowledge, which offsets decline in MPK from having more capital

According to the Solow​ model, how would each of the following events affect​ long-run living​ standards? An increase in the savings rate would ​__________ long-run living standards. An increase in the population growth rate would ___________ long-run living standards. A​ one-time improvement in productivity would _________ ​long-run living standards.

Increase Reduce Increase

Which of the statements​ below, regarding the functions of​ money, is​ true?

Money serves as a medium of​ exchange, as a unit of​ account, and as a store of value.

How can saving be increased? •

One way is to raise the real interest rate to encourage saving; but the response of saving to changes in the real interest rate seems to be small • Another way is to increase government saving - The government could reduce the deficit or run a surplus - But under Ricardian equivalence, tax increases to reduce the deficit won't affect national saving

Quantity theory of money:

Real money demand is proportional to real income • Assumes constant velocity, where velocity isn't affected by income or interest rates

An increase in productivity causes long run output, consumption, and capital per worker to

Rise higher productivity directly raises output by raising income. also raises saving and capital stock

- Interest elasticity of money demand

Small and negative: Higher interest rate on nonmonetary assets reduces money demand slightly

___________________________ is the dominant factor determining how quickly living standards rise

The rate of productivity improvement

How is the level of real income related to money​ demand?

They are directly related- the higher the level of real​ income, the higher the demand for money.

How does the expected rate of return on an asset affect its​ desirability?

They are directly related​ - the higher the expected​ return, all else​ equal, the more attractive the asset.

How does the level of liquidity affect an​ asset's desirability?

They are directly related​ - the more liquid the​ asset, all else​ equal, the more desirable the asset.

How is the interest rate on other assets​ (stocks and bonds for​ example) related to money​ demand?

They are inversely related- the higher the interest rate on other​ assets, the lower the demand for money.

How does the level of risk affect an​ asset's desirability?

They are inversely related​ - the higher the level of​ risk, all else​ equal, the less attractive the asset.

Which of the following statements below describe what is meant by a steady​ state, in terms of the Solow​ model?​ (Assume there is no productivity​ growth)

Total​ output, total consumption and total capital all grow at the same rate​ (the growth of the labor​ force). Output per​ worker, consumption per worker and capital per worker are constant.

Why is equilibrium in the asset market described by the condition that real money supply equal real money ​demand?

When supply equals demand for​ money, demand must also equal supply for nonmonetary assets.

- The break-even inflation rate:

interest rate on nominal bonds minus real interest rate on TIPS bonds • The break-even inflation rate is a rough measure of expected inflation • TIPS bonds have lower inflation risk, so the break-even inflation rate may be too high • TIPS bonds do not have as liquid of a market, so the breakeven inflation rate may be too low • The net effect of the two effects is likely to be small, so the break-even inflation rate may be about right

According to the expectations theory of the term structure of interest rates

investors compare bonds with different times to maturity and choose the ones that yield the highest return.

The key factor in economic growth

is productivity improvement • Productivity improvement raises output per worker for a given level of the capital-labor ratio

Define the velocity of money.

it is the ratio of nominal GDP to the amount of money in circulation.

• Durable goods production is _________ than nondurable goods and services • Investment spending is__________ than consumption

more volatile more volatile

Money demand _______ as real income rises

rises, because more income means more transactions - But money demand isn't proportional to real income, since higher-income individuals use money more efficiently, and since a country's financial sophistication grows as its income rises (use of credit and more sophisticated assets) - Result: Money demand rises less than 1-to-1 with a rise in real income

Why​ isn't the expectations theory sufficient to describe the data on interest rates that we​ observe?

procyclical and countercyclical ​leading, coincident, and lagging

Nominal money demand is _________ to the price level

proportional because higher price means more money needed for transactions

Classical economists think prices adjust​ _____ and that antirecessionary policies are​ _____, whereas Keynesian economists think the opposite.

rapidly, not neccesary

An increase in saving rate causes long run output, consumption, and capital per worker to

rise because higher savings allows for more investment and larger capital stock

What is the relationship between the equilibrium price level and the nominal money​ supply?

the equilibrium price level is proportional to the nominal money supply.

Price elasticity of money demand is_________, so money demand is proportional to the price level

unitary

Coincident, leading, and lagging variables

• Coincident: industrial production, consumption, business fixed investment, employment • Leading: residential investment, inventory investment, average labor productivity, money growth, stock prices • Lagging: inflation, nominal interest rates • Timing not designated: government purchases, real wage

- How does the central bank of a country increase the money supply?

• Could also buy newly issued government bonds directly from the government (i.e., the Treasury) - This is the same as the government financing its expenditures directly by printing money - This happens frequently in some countries (though is forbidden by law in the United States)

The M1 monetary aggregate

• Currency and traveler's checks held by the public • Transaction accounts on which checks may be drawn - All components of M1 are used in making payments, so M1 is the closest money measure to our theoretical description of money

Should a policy goal be to raise the saving rate?

• Not necessarily, since the cost is lower consumption in the short run • There is a trade-off between present and future consumption

- Income elasticity of money demand • - Price elasticity of money demand is unitary, so money demand is proportional to the price level

• Positive: Higher income increases money demand • Less than one: Higher income increases money demand less than proportionately • Goldfeld's results: income elasticity = 2/3

- How does the central bank of a country increase the money supply? reduce?

• Use newly printed money to buy financial assets from the public—an open-market purchase • To reduce the money supply, sell financial assets to the public to remove money from circulation—an open-market sale
