By what proportion does per capita GDP change in the long run in response to each of the following changes? (a) The investment rate doubles (b) the depreciation rate falls by 10% (c) The productivity level rises by 10% (d) an earthquake destroys 75% of the capital stock (e) A more generous immigration policy leads the population to double.Based on the Neoclassical Growth Model explain in detail what are the critical determinants of economic growth. Also, specify related assumptions.
- The COVID-19 pandemic has caused an unprecedented increase in savings in many countries around the world. In the EU, the savings rate of households has jumped from 12.5% to 17%. In 2008-2009, it had moved from 12.5% to 14% (Dossche and Zlatanos 2020). Even if the source of 2020 surge in savings is different from the one of 2008, it is obvious that this increase does not result in more investment and growth. QUESTION: 1. With reference to the paradox of thrift discuss the appropriate approach by the government to get the economy out of economic downturn swiftlyAssume a hypothetical society that decides to reduce consumption (production of consumption goods) and increase investment (production of capital goods). How would this change affect economic growth? What groups in society would benefit from this change? What groups might be hurt?Q)If the economy is in a steady state, then A. both consumption per worker and capital per worker are decreasing. B. both consumption per worker and capital per worker are constant. C. consumption per worker is decreasing but capital per worker is constant. D. consumption per worker is constant but capital per worker is decreasing.
- What two variables are most important for sustained long-run growth? options: Increasing capital and increasing total factor productivity Decreasing taxes and increasing government expenditures Increasing money supply and decreasing interest rates Increasing consumption and increasing investment in inventoriesIn class we argued that if people could accumulate human as well as physical capital, the production function would look like the “AK” production function. • (a) If the production function is AK and the savings rate is constant at rate “s”, and the rates of depreciation and populati on growth are δ and n respectively, what would the growth rate of the economy be? • (b) What would be the macroeconomic consequences of decreasing the savings rate in this economy? • (c) What would be the consequences of an increase in fertility in this economy? • (d) Would the consequences of decreasing fertility be UNAMBIGUOUSLY GOOD? • (e) Can human capital grow without bounds? Explain why or why not (make sure you discuss the physical nature of human capital). • (f) What is the growth rate of the economy (in the absence of technological progress) if human capital cannot grow without bounds?In developed countries the phenomenon of population aging is happening because of longer life expectancy as well as lower birth rates and lower population growth rates. 1. Explain how the life-cycle theory can be used to deduce that while longer expected life increases individual and aggregate savings, a lower population growth rate may increase per capita saving in the short run but reduces it in the long run. 2. How does the LC theory suggest that immigration from developing countries maybe favorable for increasing aggregate consumption and savings in developed countries? In Pakistan there is currently a pensions crisis because the government did not plan pensions of public sector employees efficiently. Instead of raising funds from lifetime earnings of employees, and giving pensions as returns on savings, pensions currently require budgetary allocation in Pakistan, leading to financial burden on government. In developed countries like the US, where people plan their own…
- Consider 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.The steady occurs when the economy is in equilibrium. Specifically, the steady state refers to the situation where K/N and Y/N are constant. K/N will not change when investment per worker equals depreciation per worker. During the adjustment process, the growth rates of Y, Y/N, and K/N will all be negative. Once the steady state is reached, these variables are constant and the growth rates will be zero. True FalseThe long-run effects of an increase in the saving rate include...? a. a higher level of productivity. b. a higher growth rate of productivity. c. a higher growth rate of income. d. All of the above are correct.
