An example of a good that is both non-rivalrous and excludable is

the source code for Microsoft Word. FEEDBACK: Page 140. Nonrivalry implies one person's use of a good does not reduce the usefulness to someone else. The park is rivalrous because you may go there to enjoy quiet, but if it is crowded and no park benches are available, the park has become less useful to you. Excludability is a restriction on the use of a particular idea. While, in principle, multiple consumers can use the same piece of software, access may be restricted by a license purchase requirement, for instance.

Structural Unemployment

obsolete job skill sets

The unemployment rate in Europe has been higher than that in the U.S. during the last two decades because:

of the combined effect of the inefficient unemployment insurance system and the productivity slowdown/high oil prices in the 1970s Page 192-194. In the 1970s European economies were hit by a productivity slowdown and high oil prices which caused an increase in unemployment. Additionally, the existence of very generous social programs in terms of size and duration coupled with a high implicit tax rate associated with returning to work encourage individuals to remain unemployed.

Why is the growth in the combined Solow-Romer is faster than the growth in the Romer model?

The effects of changes in technology are amplified by changes in the capital stock. Technological change changes output, the change in output changes savings, the change in savings changes investment, the change in investment changes the capital stock, and the change in the capital stock changes output again (subject to diminishing returns).

In the standard production model, the productivity parameter enters the equation with an exponent of one, while in the Solow model it is greater than one because:

Summarise The Principle of Transition Dynamics...

The farther below its steady state an economy is, (in percentage terms), the faster the economy will grow. The closer to its steady state, the slower the economy will grow. Allows us to understand why economies grow at different rates

Explain the history and Beginning of sustained growth

The first sustained economic growth occurred in England in the late 1700s and spread across western Europe over the next few decades. A thousand years ago, living standards were quite equal across countries—incomes differed by a factor of maybe 2. Today, living standards differ by a factor of 30, perhaps as high as 50, across countries.

What is an explanation for why an economy eventually settles in steady state?

The first two arguments taken together imply the third argument. Diminishing returns implies the slope of the investment curve becomes smaller, while depreciation remains constant. At the intersection of the two curves, net investment is zero.

Consider an economy described by the combined Solow and Romer model. If this economy is on its balanced growth path when an exogenous permanent increase in the depreciation rate occurs:

There will be an immediate growth effect Changing any parameter of the model creates transition dynamics. According to equation 6.23, an increase is the rate of depreciation immediately decreases the level of output per capita on the new balanced growth path but current income levels are the same. The economy is above its balanced growth path level of income and its growth rate will rapidly decrease in order for the economy to reach the new lower level of output per person on the balanced growth path.

What is nonrivalry?

Nonrivalry exists when one person's use of a good leaves just as much of that good for someone else. A nonrivalrous good can't be "used up."

Explain the link between Increasing returns to scale and non-rivalry

Nonrivalry: Objects are rivalrous, One person's use reduces the usefulness to someone else. BUT Ideas are nonrivalrous, National defense is nonrivalrous. This means that with Increasing returns to scale, once one person pays the cost of creating it, many people can use it without paying any extra cost. As the scale grows larger, the average cost of producing the nonrivalrous good always falls.

The influences of institutions on economic performance can be easily contrasted using:

North and South Korea

The production function of the Romer model has increasing returns to scale in . . .

Objects alone.

In Romer's influential paper he divided the economic world into . . .

Objects and ideas.

What is the rivalry of objects and ideas?

Objects are rivalrous One person's use reduces the usefulness to someone else Ideas are nonrivalrous One person's use does not reduce the usefulness to someone

Ideas vs. Objects

Objects: physical things, constant returns to scale, rival. Ideas: inspiration, don't have constant returns to scale, in the public goods sector, nonrival, public goods.

How does nonrivalry lead to increasing returns?

Once one person pays the cost of creating the good, many people can use it without paying any extra cost. As the scale grows larger, the average cost of producing the nonrivalrous good always falls.

In the Solow model, with population growth:

the economy eventually settles down to a steady state in output per person

If net investment is negative,

the economy is above its steady state and growth of output is negative.

If net investment is negative:

the economy is above its steady state and growth of output is negative.

If net investment is negative:

the economy is above its steady state and growth of output is negative. Negative net investment implies depreciation is greater than investment. Thus, the economy has a capital stock that is decreasing because it is above steady state.

If net investment is negative:

The level of consumption is largest when:

the economy is above its steady state.

The quantity theory states that the nominal GDP is equal to

the effective amount of money used in purchases.

Starting from steady state, a permanent increase in the rate of depreciation in the Solow model causes

the growth rate of output to fall temporarily and the level of GDP to fall permanently. An increase in the depreciation rate causes the depreciation curve to pivot upward, resulting in a new lower steady state. Thus, the growth rate of output is rapidly negative at first and converges to zero as it approaches steady state.

Starting from steady state, a permanent increase in the rate of depreciation in the Solow model causes

the growth rate of output to fall temporarily and the level of GDP to fall permanently.An increase in the depreciation rate causes the depreciation curve to pivot upward, resulting in a new lower steady state. Thus, the growth rate of output is rapidly negative at first and converges to zero as it approaches steady state.

An economy starts in steady state. A war causes a massive destruction of the capital stock. This shock will cause

the growth rate of output to rise initially as the economy begins to converge to the old steady state.

An economy starts in steady state. A war causes a massive destruction of the capital stock. This shock will cause

the growth rate of output to rise initially as the economy begins to converge to the old steady state. The diagram in Figure 5.1 indicates that if the capital stock is below the steady-state level of capital, the economy will proceed to the old steady-state level. Note that a shock to the level of capital will not shift any of the curves, and that the steady state remains unchanged in the long run. Because the economy is below steady state, growth is positive.

If a country is on its balanced growth path, then

the growth rates of the number of workers engaged in research and the number of researchers engaged in producing output are constant The growth rate of output is constant The growth rate of the stock of ideas is constant Page 151. Along a balanced growth path, the growth rates of all endogenous variables are constant.

In 1994 your parents made an investment of $4,000. By 2015 the investment grew to $32,000. Assuming a constant rate of growth, what was the average annual growth rate of this investment?

10 percent The data above are plotted using a ratio scale. Since this is a straight line we can conclude that the growth rate is constant. We see that the investment doubles every 7 years (i.e. for 1994 - 2001 the investment grew from $4,000 to $8,000; or use formula 3.9 to verify). Therefore, we can estimate the growth rate using the rule of 70: 70/7 = 10%

consider a perfectly competitive economy with a production function Y=AK 1/3 L2/3. There are 27 workers who produce cream cheese (a numeraire good) with 125 units of capital. If the productivity parameter is equal to 1 and the economy produces 40 tons of cream cheese in equilibrium, what is the sum of the total payments to capital and labor?

40 tons of cream cheese Since the numéraire good is cream cheese, all prices are expressed in tons of cream cheese. Total payments to capital and labor (w*L + r*K) are also expressed in tons of cream cheese. In equilibrium the sum of payments to capital and labor is equal to total production.

Solving the Solow Model

Combine the investment allocation and capital accumulation equation Substitute the fixed amount of labor into the production function If the amount of investment > depreciation - capital stock will increase until intersection -- Here, the change in capital is equal to 0. -- The capital stock will stay at this value of capital forever. -- This is called the steady state. If depreciation is greater than investment - the economy converges to the same steady state as above.

The growth rate of per capita GDP in the Romer model depends on the number of workers engaged in research. However, the country of Luxemburg, which has far fewer researchers than the U.S., grows at a rate faster than the U.S. and has a higher per capita GDP. How can the Romer model explain this difference in growth rates?

Due to the nonrivalry of ideas, the economy of Luxemburg grows because the model is based on ideas created throughout the world not just within that country. FEEDBACK: Pages 151-152. All countries benefit from all the ideas created in the world not just those created within their own borders because of the existence of international trade, multinational corporations, licensing agreements, international patent filings, the open flow of information, and migration.

24. Suppose we calculate the percent change in real GDP from year 1 to year 2 using both the Laspeyres and the Paasche indices. With the Laspeyres index we get 12 percent and with the Paasche index we get 9 percent. The chain-weighted growth of real GDP is: a. 1.5 percent d. 9.5 percent b. 9.75 percent e. 10.5 percent c. 1.33 percent

The era of modern economic growth began about: a. the time of the Egyptian pharaohs d. the time of the Renaissance b. 500 years ago e. 300 years ago c. the time of Caesar

The law of diminishing marginal product to capital means that as we add additional units of capital: A And labor, output will increase but at a constant rate B And labor, output will increase but at a decreasing rate C But hold labor constant, output will increase but at an increasing rate D But hold labor constant, output will increase but at a constant rate E But hold labor constant, output will increase but at a decreasing rate

E But hold labor constant, output will increase but at a decreasing rate

One explanation for the difference between the predicted output per person and the observed per capita GDP in Table 4.1 is the differences in:

Factor productivity

If a variable is growing at a positive constant rate, when plotted on a ratio scale, the slope of the plot will be becoming steeper over time.

False

If an economy has a higher investment rate and a higher depreciation rate, the economy will have a higher level of output.

False

If output is above potential, so that (Y~t) is positive, the change in the inflation rate will be negative, so inflation will fall over time

False

If the marginal product of capital is less than the rental rate of capital, the firm should rent more capital.

False

If the production function is given by Y = K^1/3 x L^2/3, then labor's share of GDP is one-third. True False

False

If an economy has a higher investment rate and a higher depreciation rate, the economy will have a higher level of output.

False Imagine an economy with a given rate of depreciation and investment. An economy with higher rates will have depreciation and investment curves that are both higher in the Solow diagram. Whether the steady state is higher or lower depends on the magnitudes of the parameters. Thus, we cannot determine the output definitively—it may be higher, lower, or the same.

The Solow model is a static model and thus can only tell us the levels of our endogenous variables in steady state.

False The Solow model is a dynamic model. Although we can only mathematically solve for the endogenous variables in steady state, they are subscripted by time because the model holds at all points in time.

The investment rate in a particular economy is a function of the amount of output (income) an economy generates each year. T/F

False Although rich and poor countries often have different investment rates, the investment rate is an exogenously given parameter in the Solow model. Unless shocked, it does not change over time.

Patents are unambiguously beneficial to society because they create profits for firms, which generate incentives to produce new ideas

False Page 144. Patents also distort the economy by generating welfare loss

During the era of the new economy, growth accounting shows that the increase in growth during the era is accounted for in roughly equal parts by capital and TFP growth.

False Page 161. Capital and TFP growth were both important to the new economy. New inventions related to computer technology and purchasing new computers were both important.

Bob is not employed by anyone, and he does not care about finding a job and is not searching for a job. Bob is unemployed.

False Page 182. To be considered unemployed, a person must be actively looking for a job in the four weeks prior to measuring the unemployment rate.

The natural rate of unemployment can be reduced to zero percent

False Page 189. The natural rate of unemployment includes frictional and structural unemployment. Even if structural unemployment is eliminated, frictional unemployment will remain because it stems from workers changing jobs in a dynamic economy.

Increasing wages beyond the wage rate needed to retain a worker will definitely decrease a firm's profit.

False Page 193. The theory of efficiency wages implies that a firm may increase profit by raising wages. One reason for this is that the firm will attract workers that are more able.

According to the quantity theory of money, increases in the money supply and in real GDP will cause inflation.

False Page 219-220. After solving the quantity theory of money model, we realize that increases in the money supply and decreases in real GDP will cause inflation.

Empirically, money is neutral in the short run as well as the long run.

False Page 222-223. The neutrality of money fails in the short run, because nominal prices do not respond immediately to changes in the money supply.

If price equals marginal cost, firms will have adequate incentives to produce new ideas.

False Pages 143-144. As long as a fixed cost to producing the idea exists, firms will then have no incentive to create an idea because they must recover this fixed cost in order to stay profitable.

The Solow and Romer models explain why countries have different TFP levels and investment rates.

False Pages 163-164. The Solow and Romer models leave this question unanswered. Perhaps institutions or other factors not in the model may explain these concepts.

Workers in Europe work fewer hours than in the United States, and thus per capita GDP is lower in Europe. Because per capita income is lower in Europe, Europeans are clearly worse off in terms of welfare than Americans.

False Pages 194-195. If working less is voluntary (Europeans prefer leisure more than Americans do), then this decision is likely to be welfare enhancing.

The inflation tax will affect an individual who holds all his assets in artwork.

False Pages 228-229. Holders of currency only pay the inflation tax. Because all prices in the economy are influenced by the inflation tax, the value of the artwork changes proportionately with all other prices.

If an economy has a higher investment rate and a higher depreciation rate, the economy will have a higher level of output. T/F

False We cannot tell where the steady states are from this info

Give 3 useful mathematical properties of growth rates...

Growth rates obey mathematical operations that are a level simpler than the operation on the original variable Variables divided => growth rates subtracted Variables multiplied => growth rates added Variable taken to a power number => growth rate multiplied by that number

The neutrality of money says that changes in the money supply...

Have no real effects on the economy and Only affect prices Empirically, this Holds in the long run buy Does not hold in the short run. nominal prices do not respond immediately to changes in the money supply

According to the Solow model, in the steady state, countries with high saving rates should have a . . .

High capital-output ratio.

What is higher steady state production caused by?

Higher productivity (Abar) and investment rate (s).

Labor demand is a function of the marginal product of labor, changes in output prices, and labor regulation. A heavily regulated labor market reduces the demand for labor. Removing these restrictions would increase the demand for young labor and commensurately increase their wages.

Historically, young French workers (under age 25) have had relatively high unemployment rates: 21 percent in 2005. In 2006, the French government proposed to allow employers to fire young employees without cause (eliminating a labor restriction). How should this policy improve employment prospects for young French workers? What would the impact be on their wages? Use a graph to guide your analysis.

What does a production function tell us?

How much output can be produced given any number of inputs, laborers, and machines.

Liquidity is a measure of:

How quickly an asset can be converted to currency

What explains TFP differences?

Human capital Technology Institutions Misallocation

4 factors impact TFP, what are these and how do they work?

Human capital - Stock of skills that individuals accumulate to make them more productive - Education and training Technology - Richer countries may use more modern and efficient technologies than poor countries. - Increases productivity parameter Institutions - are in place to foster human capital and technological growth by... - Property rights - The rule of law - Government systems - Contract enforcement Misallocation - Resources not being put to their best use e.g. - Inefficiency of state-run resources - Political interference

Why are some countries more efficient at using capital and labor?

Human capital, technology, and institutions.

If the price level in year 1 was equal to 100 and the price level in year 2 was equal to 1,000, in year 2 the country is experiencing:

Hyperinflation Pages 212-213. The inflation rate is measured with the annual percentage change in the price level . In this case, the inflation rate is 900%. An episode of extremely high inflation is known as hyperinflation.

To recap, in the Solow Model, what is the allocation of resources equation?

I = sbar x Y

You want to deposit $625 in a savings account. If you choose bank A, your balance will be $756 in two years (bank A pays interest annually). However, you know that banks B and C also offer savings accounts: bank B pays an annual interest of 9% while bank C pays an annual interest of 10%. Assuming that you plan to keep your money in the bank for two years, which bank should you choose? Round to 1 decimal place.

I am indifferent between Bank A and Bank C Page 195. Given that bank B pays annual interest of 9%, bank C is preferred to bank B. To find the interest rate paid by bank A, use formula 7.7 where the present discounted value is $625, the future value is $756, and T=2, then solve for the interest rate:

Use the Solow model to explain what happens to the economy with a decrease in the investment rate.

In period 1, consumption increases and investment decreases resulting in negative net investment, but capital stock and output (income) do not change. In period 2, the capital stock will start falling toward its new steady-state level. At first, the drop in capital stock will be rapid (net investment is the most negative), but eventually it will come to rest at the new, lower level of capital stock.

What is the principle of transition dynamics in the combined Solow-Romer model?

In the Solow-Romer model, the economy has a balance rate of growth, where the capital stock, output, and total factor productivity grow at constant rates. A change in the underlying parameters of the model can alter the growth rate temporarily, but due to diminishing returns to capital the economy will transition back to a balanced rate of growth. The further it is below its balanced growth per capita output, the faster it will bounce back.

Solving mathematically for the steady state...

In the steady state, investment equals depreciation. Substitute into the production function: Solve for K* The steady state level of capital is: Positively related to the - investment rate - the size of the workforce - the productivity of the economy Negatively correlated with - the depreciation rate

Regarding The Rising Return to Education, what should happen theoretically and what has happened in actuality?

In theory: wages↑ → supply↑ → wages↓ In actuality: Wages↑ → supply↑ → demand↑ → ∆demand>supply → wages↑

The great inflation of the 1970s was partially caused by:

Increases in oil prices, and a money supply that was growing too quickly. Pages 232. Both B and C are correct. Increase in oil prices spurred inflation while the Federal Reserve made mistakes in running a monetary policy that was too loose.

Nonrivalry of ideas and the standard replication argument imply the production function will have

Increasing returns to scale Pages 142-143. The standard replication argument implies we can double output by doubling objects, but ideas are nonrivalrous and can be used in two duplicate factories simultaneously.

The Solow model experiences transition dynamics, The Romer model however does not. What occurs instead?

Instead, has balanced growth path Constant growth rates of all endogenous variables

What is the The marginal product of capital (MPK) and how is it found?

The additional output that is produced when one unit of capital is added, holding all other inputs constant. This is found by taking the derivative of the production function with respect to capital

Under the classical dichotomy, which of the following does not determine real GDP in the long run?

The aggregate price level Pages 218-219. In the long run, real GDP is only determined by real considerations and not based on variables, such as money or the aggregate price level.

What is the depreciation rate?

The amount of capital that wears out each period. Must be between 0 and 1 in Solow model. Usually between 7 and 10 percent.

In the Solow model, if capital is in the steady state, output is...

also in the steady state.

In "The cost of innovation has risen, and productivity has suffered", the Economist magazine discusses research by Bloom, Jones, Van Reenen, and Webb. They find evidence that productivity growth has been fairly constant in recent decades while the number of researchers has risen very sharply. How can the Romer model reviewed in class be reconciled with this empirical evidence? Hint: Use the equations of the Romer model to answer this question.

The fraction of researcher must be rising while their productivity is declining at the same time.

According to the principle of transition dynamics, which economy will grow fastest?

The same country 1 year after the natural disaster destroyed most of the capital stock The principle of transition dynamics says that an economy that is farther below its steady state will grow faster. The destruction of the capital stock places the economy further below its steady state 1 year after the destruction took place.

According to the principle of transition dynamics, which economy will grow fastest?

The same country 1 year after the natural disaster destroyed most of the capital stockThe principle of transition dynamics says that an economy that is farther below its steady state will grow faster.

In the Cobb-Douglas production function Y=KαL1-α, the α represents:

The share of income claimed by owners of capital

Explain the concept of wave rigidity

The workers are rendered unemployed because at a given wage rate supply of labour exceeds demand for labour. ... It may be noted that stickiness or rigidity of money wage implies that money wage rate will not quickly change, especially in the downward direction to keep equilibrium at full employment level.

Efficiency Wages

Theory that if you raise wages, people will become more productive.

If there are constant returns to all inputs together, then . . .

There are diminishing returns to each input by itself.

In the Solow diagram, an increase in the investment rate will cause a decrease in consumption for all levels of capital.

True Consumption is the difference between the production function and the investment curve. This distance is everywhere smaller as the investment rate increases.

Total factor productivity explains a larger amount of the difference in income per capita in the Solow model than in the production model.

True TFP explains a larger difference in the Solow model, because productivity influences output in both models but also influences capital accumulation in the Solow model.

In the long run, the real interest rate is equal to the marginal product of capital.

True The return to saving must equal the return to investment, which implies that the real interest rate equals the rental price of capital, which is equal to the MPK.

The change in the capital stock is a flow variable. T/F

True A flow variable is one that lasts only for one period. Capital alone is a stock variable, but the change in capital is a flow variable.

Output per person in the long run can be higher than before a shock occurs, even if the shock causes the level of output per person to fall immediately.

True Page 154. Notice in Figure 6.4, the level of output per person is higher in the long run even though the shock initially causes a decrease; this will be the case when a positive-growth effect happens in addition to the level effect.

If real GDP is growing at a rate of 2 percent, the central bank should grow the money supply at a rate of 2 percent to keep prices unchanged.

True Page 220. Prices are stable if the inflation rate is 0 percent and this occurs when the growth rate in the money supply is equal to the growth rate of real output.

If the real interest rate is 3 percent and the nominal interest rate is 1 percent then the economy is experiencing deflation according to the Fisher equation.

True Page 223. The inflation rate is equal to the nominal interest rate minus the real interest rate, which is negative in this example.

High inflation leads to inefficient resource allocation.

True Page 226. When inflation is high, some prices adjust faster, and other prices adjust more slowly. This leads to a distortion of relative prices, which leads to an inefficient allocation of resources.

Nonrivalry of ideas implies that per capita GDP depends on the total stock of ideas and not on ideas per person.

True Pages 140-141. Because ideas are nonrival, a new idea can be used by all and thus need not run into diminishing returns like capital does in the Solow model.

The labor demand curve slopes downward because the marginal product of labor is diminishing as we add additional labor.

True Pages 184-185. The labor demand curve is derived from the firm's maximization problem. As we add more workers and other inputs are fixed, each additional worker produces less.

If a tax is imposed on labor supply and wages are rigid, wages and the employment-population ratio will be lower than the market clearing level after the shock.

True Pages 185-188. A tax on labor supply will shift the supply curve to the left and equilibrium wages will rise. However, if wages are rigid, they will remain low and employment will decrease as fewer people are willing to work.

Let us suppose that you open a savings account at the campus credit union. Into this savings account, you place $100 in savings. The interest rate is 5 percent. The future value of this account in two years is $110.25.

True Pages 195-196. Manipulating equation 7.7 implies that the future value is equal to 100*(1 + .05)^2.

High inflation may result if central banks are not independent from the branches of government responsible for spending and taxation,

True Pages 220, 229. If the government is able to finance its spending mainly through an expansion of the money supply, the result will be higher inflation (equation 8.4). Therefore, limiting the government's ability to print money will limit inflation.

Total factor productivity explains a larger amount of the difference in income per capita in the Solow model than in the production model.

True TFP explains a larger difference in the Solow model, because productivity influences output in both models but also influences capital accumulation in the Solow model.

In the long run, the real interest rate is equal to the marginal product of capital. T/F

True The return to saving must equal the return to investment, which implies that the real interest rate equals the rental price of capital, which is equal to the MPK.

hyperinflation ages 206-207. The inflation rate is measured with the annual percentage change in the price level . In this case, the inflation rate is 900%. An episode of extremely high inflation is known as hyperinflation.

Consider the Solow model exhibited in Figure 5.4. Which of the following is/are true? i. For any single country, the movement from point a to b is due to an increase in the saving rate, s1 > s2.ii. For any single country, the movement from point c to b is due to an increase in capital stock for the saving rate, s2.iii. If s1 and s2 stand for the saving rates in Countries 1 and 2, respectively, Country 2 has a lower saving rate.

i,i,iii

If there are large fixed or research and development costs, such as in the pharmaceutical industry, production can be characterized by:

increasing returns to scale

Nonrivalry of ideas and the standard replication argument imply the production function will have

increasing returns to scale. FEEDBACK: Pages 142-143. The standard replication argument implies we can double output by doubling objects, but ideas are nonrivalrous and can be used in two duplicate factories simultaneously.

Consider an economy described by the textbook Solow model with a production function. The economy is producing 100 units of output and the productivity parameter is equal to 1. If the depreciation rate is 6%, the investment rate is 6%, and there are 125 workers, the growth rate of the economy_____:

is positive because the economy is below its steady state. Replace the given numbers in equation 5.7 and solve for the steady state level of capital: K* = 125. Therefore, Y* = 5 * 25 = 125. If the economy currently produces 100 units of output according to the Solow diagram it is below its steady state and the growth rate of the economy is positive.

is positive because the economy is below its steady state. Replace the given numbers in equation 5.7 and solve for the steady state level of capital: K = 125. Therefore, Y = 5 * 25 = 125. If the economy currently produces 100 units of output according to the Solow diagram it is below its steady state and the growth rate of the economy is positive

A government is more likely to utilize the inflation tax if

it is running a budget deficit. lenders worry that the government will not pay back its debts. politicians will not raise taxes, because they cannot be reelected if they do. Pages 221-222. The inflation tax is likely to be used as a last resort. If deficits are high and additional borrowing and taxing are impossible, the inflation tax will be used to raise revenue.

One problem with unexpected changes in inflation is that:

it often comes in surprising and unpredictable ways

The wholesale price of one pound of coffee was 8.25 cents in 1900 and $1.50 in 2015. If the CPI was 3.43 for 1900 and 100 for 2015, coffee was

less expensive in 2015 compared to 1900. Pages 208-209. We can find the equivalent 2015 value of the 1900 price using the equation: value in 1900* (CPI2015/CPI1900). Thus, the equivalent 2015 value of $0.0825 is $2.41, which makes coffee less expensive in 2015. FEEDBACK: Pages 208-209. We can find the equivalent 2015 value of the 1900 price using the equation: value in 1900*(CPI2015/CPI1900). Thus, the equivalent 2015 value of $0.0825 is $2.41, which makes coffee less expensive in 2015.

In the standard production model's production function, the productivity parameter enters the equation with an exponent of one, while in the Solow model's equation for the steady-state stock of capital it is greater than one because:

the endogenous level of the capital stock itself depends on productivity.

the equilibrium quantity of labor, L*, and wage, w*

The Cobb-Douglas Production Function has diminishing returns as...

the function is globally convex. We can also see this algebraically when taking the 2nd derivative with respect to both L and K and see that they are both < 0

The principle of transition dynamics can be summarized as...

the further below its steady state an economy is, the faster the economy will grow.

The principle of transition dynamics can be summarized as:

the further below its steady state an economy is, the faster the economy will grow.

The Great Inflation of the 1970s was partially caused by:

the inflation tax used to finance the Vietnam War. increases in oil prices. a money supply that was growing too quickly. Pages 225. Both "increases in oil prices" and "a money supply that was growing too quickly" are correct. Increase in oil prices spurred inflation while the Federal Reserve made mistakes in running a monetary policy that was too loose.

The relative wages of college graduates have been increasing as a result of:

the scarcity of highly educated workers in the global economy Pages 197-201. The relative wages of college graduates have been increasing due to (1) large shifts in the demand curve as a result of globalization (scarcity of highly educated workers in the global economy) and skill-biased technical change. The shifts in the market for college graduates have to be larger than the shifts in the market for high school graduates in order for the relative wage to rise.

To get increasing RTS using the production function Yt = At(Kt^1/3)(Lt^2/3), we need to replace TFP with:

the stock of ideas, At

To get increasing returns to scale using the production function, Yt = A Kt^1/3 Lt^1/3 we need to replace total factor productivity with:

the stock of ideas, At

Suppose we compare GDP per person in Uganda and the United States in two ways: first using the exchange rate method and second using the relative price-based conversion as well. Then, Uganda appears to be richer under the relative price-based conversion than with the exchange rate conversion.

true

The classical school does not believe in money illusion.

true

The monetary base equals bank reserves and currency in circulation.

true

true

The monetary base contains elements that are more liquid than M2.

true Page 210. The broader measures of the money supply (M2 is broader than the monetary base) contain accounts that are less liquid. Thus, the monetary base is more liquid.

If we define sbar1 and sbar2 as the saving rates in Countries 1 and 2, respectively, dbar1 = dbar2 as the depreciation rates in Countries 1 and 2, respectively, and Abar1 and Abar2 as productivity in Countries 1 and 2, respectively, in the Solow model, the equation ________ predicts that ________ differences contribute the most to differences in steady-state output per worker.
