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.

Consider an economy characterized by the production function Y= AK 1/2L1/2 where the productivity parameter is equal to 1.2. How many units of output can be produced with 25 units of capital and 64 workers?

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.

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

is also in the steady state.

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

In the Solow model, in every period, a fraction of total output ________, which ________ next period's capital stock.

is saved; adds to

When comparing shares of consumption in GDP it is best to use ( ___ ) variables. When comparing real rates of economic growth it is best to use ( ___ ) variables.

nominal; chain-weighted

The difference between economic profits and normal profits is that:

normal profits are earnings based on the normal competitive return to one's own labor; economic profits are the above-normal returns associated with prices that exceed competitive prices

Which of the following is an exogenous variable in the Solow model?

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.

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.

How quickly GDP doubles will depend on:

the growth rate of GDP

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.

true

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.

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:
