According the Harrod-Domar and Solow models, what should countries do if they want to grow?
According to the Solow-Swan model, for a country that is initially in steady state, if the technology
parameter A rises, then:
the per capita capital stock initially increases, then returns to its initial steady state level
the per capita capital stock decreases and the country moves to a new, lower steady state level of per capita
income
the per capita capital stock initially decreases, then returns to its initial steady state level
O the per capita capital stock increases and the country moves to a new, higher steady state level of per capita
income
When a country adds capital what is it doing to its productivity and GDP? Which variable in the Solow Model equation is it changing?

Let the saving rate θ = 0.75. Per capita output (y) is equal to 100 and the percapita capital stock (k) is 1000. For Solow to be in steady state: a.the depreciation rate is 0.025 and the population growth rate is 0.05 b.the depreciation rate is 0.25 and the population growth rate is 0.5 c.the sum of the depreciation rate and the population growth rate must be less than 0.075 d.the depreciation rate and population growth rate must sum to 0.75arrow_forward
- in the solow model with no population and technological progress what happensarrow_forwardwhen a country adds capital what is it doing to its productivity and GDP? Which variable in the Solow Model equation is it changing?arrow_forwardI have to change the savings rate, but trying to figure out how to start. Let’s work out 5 periods of a Solow model with labor augmenting productivity (Z) growth. In your toy economy, the savings rate is 10%, and the depreciation rate is 50% (the high depreciation rate will get us to steady-state faster--think of each period as a decade). The population is fixed (treat it as one worker, N=1 forever). You always start off with 1 unit of capital, and TFP = Z = 1 during the first period. Since TFP and population never change, output each period is created this way: Yt = Kt(1/3)Zt(2/3) Consider two worlds: One where labor augmenting productivity (Z) grows 20% per period, and one where labor augmenting productivity (Z) grows 10% per period Answer the following questions for each of the two worlds What is capital each year, in years 1-5? What is GDP each year, in years 1-5? What is the marginal product of capital each year (MPK) in years 1-5? What is the wage in each period? In a steady…arrow_forward
- QUESTION 4 The Solow model says that the faster productivity grows, the slower the K/AL ratio grows. This is because: Productivity growth increases output, but does not directly increase the capital stock Productivity growth increase the size of the capital stock directly, but does not directly increase output Productivity growth has no effect on output, but does increase the capital stock directly Productivity growth decreases the size of the capital stock directly, but does not directly increase output O O O Oarrow_forwardGood Evening My name is Helen here's the problem A country is described by the solow model, with production function of y=k1/2, Suppose that k is equal to 400. The fraction of output invested is 50%. the depreciation is 5%. Is the country at its steady-state level of output per worker, above the steady state, or below the steady state? Show how you reached your conclusion.arrow_forwardWhich of the following two countries A and B ceteris paribus do you expect to have the higher steady-state level of GDP per capita? Moreover, which country do you expect to grow faster? For this, you may assume that both countries will initially start their growth paths below their corresponding steady states. a) The two countries have initially the same levels of GDP per capita but country A has a higher savings rate . b) The two countries have initially the same levels of GDP per capita but population in country A grows at a rate of 10% while in country B population grows at a rate of 8%. c) The two countries have initially the same levels of GDP per capita but the average educational attainment of workers in country A is about 1.2 times higher than in country B.arrow_forward
