Suppose that a group of consumer activists claims that drug companies earn excessive profits because of the patents they have on drugs. The activists advocate cutting the length of time that a drug company can hold a patent to five years. They argue that this will lead to lower prices for drugs because competitors will enter the market after the five-year period. Do you see any drawbacks to this proposal? A. It will reduce the incentive for drug companies to invent new drugs. B. It will result in only induced innovation. C. It will promote "creative destruction," as outlined by Joseph Schumpeter. D. All of the above.
A. It will reduce the incentive for drug companies to invent new drugs.

What are some of the factors that would explain why the innovative restaurants are found in big cities? (Check all that apply.) A. Larger cities allow for the specialization of labor, which can lead to greater creativity among chefs. B. Restaurants in large markets don't have to invest in human capital and can instead focus on the creativity of their dishes. C. In larger markets, restaurants have more incentives to come up with innovative and creative new dishes. D. These awards are strategically given to a restaurant in large markets to attract more growth to these megacities. E. There are more chances to have face-to-face interactions, which can lead to increased innovation and creativity.
A. Larger cities allow for the specialization of labor, which can lead to greater creativity among chefs. C. In larger markets, restaurants have more incentives to come up with innovative and creative new dishes. E. There are more chances to have face-to-face interactions, which can lead to increased innovation and creativity.

A. True Governments can play a key role in designing institutions that promote economic growth, including providing secure property rights.
Education can contribute to economic growth by A. complementing physical capital and developing new ideas. B. enhancing technology and raising wages. C. increasing wages and employment. D. providing employment and literacy.
A. complementing physical capital and developing new ideas.
Computers have revolutionized banking for consumers through the growth of ATMs and electronic bill paying capabilities. All of these improvements for consumers might not be counted as technological progress because technological progress A. is defined by economists as an increase in output with no additional increases in inputs. B. cannot be counted. C. occurs only in some sectors and not in others. D. is defined by economists as an increase in buildings and equipment.
A. is defined by economists as an increase in output with no additional increases in inputs. Technological progress is an increase in output with no additional increases in inputs. Not all technological innovations constitute technological progress. Some add convenience rather than the ability to increase output with no additional increases in inputs.
Suppose that GDP is $18 trillion in year 1, and $19 trillion in year 2. Which of the following statements is true? A. The growth rate of GDP is 4.25%. B. It will take 12.6 years for GDP to double. C. The growth rate of GDP is 5.26%. D. It will take 16.5 years for GDP to double.
B. It will take 12.6 years for GDP to double. - The growth rate of a variable is the percentage change in that variable from one period to another. Real GDP per capita is GDP/population. GDP is $18 trillion in year 1, and $19 trillion in year 2. Growth rate of GDP = (19 - 18 / 18) x 100 = 5.55%. Years to double for GDP = 70 / 5.55= 12.6 years. REMEMBER: when referring to doubling, use 70
Suppose a country makes substantial investments to improve its roads. Give an example(s) of how this would improve productivity in the economy as a whole. (Check all that apply.) A. The government's total tax revenue as a proportion of GDP would increase. B. Substantial investments to improve the roads would encourage private investment. C. The total employment elasticity of the economy would increase. D. Total transportation costs would be reduced.
B. Substantial investments to improve the roads would encourage private investment. C. The total employment elasticity of the economy would increase. Substantial investments in a country's roads reduce transportation costs and result in an improvement in infrastructure. This in turn encourages private investment.
Governments can play a key role in designing institutions that promote economic growth, including providing secure property rights. A. False B. True
B. True
Some economists are concerned about the "brain drain," the phenomenon in which highly educated workers leave developing countries to work in developed countries. Other economists have argued that "brain drain" could create incentives for others in the country to secure increased education and many of the newly educated might not emigrate.

When highly educated workers leave, more high paying jobs become available. C. When highly educated workers leave, the direct out-of-pocket costs of education decrease. D. All of the above. How would you test this theory? A. Compare wages in developing countries with and without significant "brain drain." B. Compare the types of jobs in developing countries with and without significant "brain drain." C. Compare labor productivity in developing countries with and without significant "brain drain." D. All of the above
B. When highly educated workers leave, more high paying jobs become available. D. All of the above

We can measure the effects of technological progress by measuring GDP convergence across countries. B. We can measure the effects of technological progress directly by tracking capital deepening. C. We can measure the effects of technological progress by comparing labor productivity over time. D. We can measure the effects of technological progress indirectly using growth accounting methods.
D. We can measure the effects of technological progress indirectly using growth accounting methods.
Modern theories of growth that try to explain the origins of technological progress are known as A. classical theories. B. technology theories. C. employment theories. D. new growth theories.
D. new growth theories.
Capital deepening comes to an end because of the A. reality principle. B. marginal principle. C. principle of opportunity cost. D. principle of diminishing returns.
D. principle of diminishing returns. The process of capital deepening must eventually come to an end. As the stock of capital increases, output increases, but at a decreasing rate because of diminishing returns. The process of capital deepening will come to a halt as depreciation catches up with total saving.
Growth accounting is a useful tool for A. determining comparative GDP per capita. B. examining personal income and disposable income. C. identifying the shares of consumption and investment in GDP. D. understanding different aspects of, or contributions to, economic growth.
D. understanding different aspects of, or contributions to, economic growth.
A worldwide patent and copyright system would ??? the incentive to be innovative.
Increase A worldwide patent and copyright system would increase innovation by allowing firms that invent new products and more efficient ways to produce to earn monopoly profit, protecting intellectual property rights both domestically and worldwide.
A higher saving rate leads to a permanently higher rate of growth. - true or false
false A higher saving rate will lead to a higher stock of capital in the long run. A higher saving rate will promote capital deepening. If a country saves more, it will have a higher output. But eventually, the process of economic growth through capital deepening alone comes to an end, even though this may take decades to occur.
Higher saving leads to ??? gross investment and will tend to ??? the stock of capital available for production and result in ??? depreciation because there is ??? capital to depreciate.
higher, increase, more, more
Suppose a government places a 10 percent tax on incomes and spends 60 percent of the money from taxes on investment and the rest on public consumption goods, such as military parades. Individuals save 20 percent of their income and consume the rest. In this case, total investment (public and private) - increases or decreases
increases Since the government invests a larger portion of the money than individuals, total investment increases.
??? and ??? are the two factors that determine how the stock of capital changes over time.
saving, depreciation The stock of capital depends on two factors: investment (or saving) and depreciation. The stock of capital increases with any gross investment spending (or saving) but decreases with depreciation. New capital stock − old capital stock = (gross investment −depreciation). Gross investment depends on saving, so: Change in the stock of capital = saving − depreciation
Once we account for changes in the labor force, ??? is the next biggest source of the growth of GDP in the United States. - capital growth, international trade, or technological progress
technological progress Behind increases in the labor force, technological progress has been the second-largest factor contributing to real GDP growth, accounting for roughly 35 percent of the growth in output between 1929 and 1982.
