The determinants of productivity
Consider a simple economy whose only industry is fishing. In this industry, productivity—the amount of goods and services a worker can produce per hour—is measured by the number of fish one fisherman catches per hour.
In the following table, match each example to the productivity determinant it represents.
Examples
Human Capital per Worker
Natural Resources per Worker
Physical Capital per Worker
Technological Knowledge
The fertile waters in which the fish feed and breed
An advanced mapping system that determines the likelihood of finding fish schools in different depths and locations
The skills workers develop through training before working on and piloting boats
The boats in the fishing fleet
The production function for an economy can be expressed as Y= F(K,L), where Y is real
GDP, K is the quantity of capital in the economy, and L is the quantity of labor in the
economy.
If Y = K0.5 L0.5, what is real GDP if the quantity of capital is 900 and the quantity of labor is
а.
400?

- Consider an economy with a Cobb-Douglas production function. Assume that the labour income share parameter is 1/3. The economy is producing 100 units of output and the productivity parameter is equal to 1. f the depreciation rate for capital is 6%, investment rate is 6%, and there are 125 workers in the economy. The growth rate in the economy: Select one: a. is positive because the economy is below its steady state. b. is equal to zero because the economy is at its steady state. C. is negative because the economy is above its steady state. d. cannot be determined.arrow_forwardAssume that production in an agricultural economy takes place according to Y = AT0.5 L0.5 where Y is output, A is technology, T is the amount of land and L is the labour force. This means that growth in this economy can be decomposed as follows. gy = ga +0.5g7 + 0.5gL, where gy is the growth rate of output, ga is the growth rate of technology, gT is the growth rate of land and gr, is the growth rate of the labour force. Assume that everyone in this economy works and so the labour force is equal to the population, which grows at a rate n > 0. Assume that the quantity of land is fixed. Answer all parts below: (a) Find an expression for the growth rate of per-capita income. (b) Using this equation, explain why the Malthusian Trap could be present in this economy. (c) Why might the Malthusian Trap not apply in this economy? Carefully explain under what conditions the Malthusian Trap will and will not apply in this economy.arrow_forwardI am having a problem with these four problems webdav/pid-1221589-dt-content-rid-8618514_1/courses/1678.201780/Assign2.pdf + Automatic Zoom : 19. Technological progress helps increase the productivity of labor, defined as the number of units of output produced per hour of labor.

- 10. As an alternative to the story of Robinson Crusoe, macroeconomists use the "aggregate production function," written as Y = AF(L,K,H,N), to link economy-wide output Y to the number of workers L, the stock of physical capital K, the stock of human capital H, the stock of natural resources N, and stock of technological knowledge A. With reference to this aggregate production function, please indicate whether each of the following statements is true or false. (a) The aggregate production function exhibits "constant returns to scale" if doubling the four inputs - workers L, physical capital K, human capital H, and natural resources N – while holding the stock of technological knowledge A fixed leads to a doubling of output. (b) The aggregate production function exhibits "constant returns to scale" if tripling the four inputs - workers L, physical capital K, human capital H, and natural resources N – while holding the stock of technological knowledge A fixed leads to a tripling of…arrow_forwardSuppose a country has a population of 120 people, a working-age population of 100 people, its labor force participation rate is 0.5 (50%), and the quantity of output is 60 units. Suppose that the production function of the economy is given by Y=2N, where Y represents the quantity of output and N represents the number of workers needed to produce the output. I know the answer is 0.4 but I don't understand how to get it. Thank you!arrow_forwardConsider an economy with a Cobb-Douglas production function with α = 1/3 that begins in steady state with a growth rate of technological progress of g of 2 percent. Consider what happens when g increases to 3 percent. (a) What is the growth rate of output per worker before the change? What happens to this growth rate in the long run? (b) Perform a growth accounting exercise for the economy, decomposing the growth rate in output per capita into components contributed by capital per capita growth and technology growth. What is the contribution of the change in g to output per capita growth according to this formula? (c) In what sense is the growth accounting result in part b producing a misleading picture of this experiment? Explain why this is the case.arrow_forward
