Suppose that 10 workers were required in 2010 to produce 40,000 bushels of wheat on a 1,000-acre farm. a. What is the average output per acre? Per worker? b. If in 2020 only 8 workers produce 44,000 bushels of wheat on that same 1,000-acre farm, what will be the average output per acre? Per worker? c. By what percentage does productivity (output per worker) increase over those 10 years? Over those 10 years, what is the average annual percentage increase in productivity?
Suppose an economy’s production function is Y = AKαL1−α. If the annual rate of economic growth is 3.5 per cent and labour and capital are both growing by 2 per cent annually, what contribution to growth is made by total factor productivity? You can assume that labour receives 75 per cent of the total income generated in this economy.
(Words apart) Per capita income most recently was about 160 times greater in the US that in Democratic Republic of the Congo. Suppose per capita income grows an average of 3 percent per year in the richer country and 6 percent per year in the poorer country. Assuming such growth rates continue indefinitely into the future, how many years would it take before per capita income in the Congo exceeds that of the US? (to simplify the math, suppose at the outset per capita income is $160000 in the richer country and $1000 in the poorer country.)

Thus, if Mexico’s real GDP per person is growing at 7 percent per year, it will take about 10 years (= 70/7) to double. Apply the rule of 70 to solve the following problem. Real GDP per person in Mexico in 2005 was about $11,000 per person, while it was about $44,000 per person in the United States. If real GDP per person in Mexico grows at the rate of 4 percent per year, about how long will it take Mexico’s real GDP per person to reach the level that the United States was at in 2005? (Hint: How many times would Mexico’s 2005 real GDP per person have to double to reach the United States’ 2005 real GDP per person?) Instructions: Enter your answer as a whole number.arrow_forward
- How can we measure growth over the very long run? Te poorest countries in the world have a per capita income of about $600 today. We can reason-ably assume that it is nearly impossible to live on an income below half this level (below $300). Per capita income in the United States in 2015 was about$51,000. With this information in mind, consider the following questions.(a) For how long is it possible that per capita income in the United Stateshas been growing at an average annual rate of 2% per year?(b) Some economists have argued that growth rates are mismeasured. Forexample, it may be difcult to compare per capita income today with percapita income a century ago when so many of the goods we can buy todaywere not available at any price then. Suppose the true growth rate in thepast century was 3% per year rather than 2%. What would the level of percapita income in 1800 have been in this case? Is this answer plausible?arrow_forwardWhy is per capita gross domestic product (per capita GDP) better than gross domestic product (GDP) as a measure of a country's wealth? O Location and land mass have a large effect on GDP and must be considered in assessing a country's economy. O Because per capita GDP takes population into account, it is more useful for comparing the standard of living in different countries. O Per capita GDP provides information on income, while GDP only provides information on investment. O Per capita GDP includes the value of land, minerals, and crops not counted by normal GDP. The advantages of the sole proprietorship include O ease of start-up © full control ob business decisions © exclusive rights to profits © all of the abovearrow_forwardAlthough economic growth is typically measured by calculating the rate of changein real GDP, there are a few problems associated with the use of GDP as ameasure of economic growth.Identify these problems.(4)Q.3.2 Economic growth can originate from the demand side or from the supply side ofthe economy.

- Country A and country B both have the production function Y = F(K, L) = K1/3L2/3 Does this production function have constant returns to scale? Explain. Find Solow’s production function, y = f (k)? Assume that neither country experiences population growth or technological progress and that 20 percent of capital depreciates each year. Assume further that country A saves 10 percent of output each year and country B saves 30 percent of output each year. Find the steady-state level of capital per worker for each country, then find the steady-state levels of income per worker and consumption per worker. Suppose that both countries start off with a capital stock per worker of 2. What are the levels of income per worker and consumption per worker? Remembering that the change in the capital stock is investment less depreciation, use a calculator (or, better yet, a computer spreadsheet) to show how the capital stock per worker will evolve over time in both countries.

What is New Zombie’s real GDP? If work hours increase to 210 in year 2 and productivity rises to $10 per hour, what is New Zombie’s rate of economic growth? Explain why sustained long-term economic growth comes from increases in labor productivity. Why do you think the trend rate of U.S. productivity growth has increased since the earlier 1973–1995 period? The quantity of labor and increases in labor productivity are important sources of economic growth. Between 1953 and 2015, in the US economy the labor force increased from 63 million to 158 million workers. Productivity growth has usually been the more significant factor. To calculate real GDP in a given year you have to multiply hours worked by productivity. Suppose that New Zombie has adopted the framework used by the US Bureau of Labor Statistics to calculate its labor force statistics. Following information is extracted from a…arrow_forward
