- 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.Suppose, a country X has a GDP level of 4, 50,000 and a growth rate of 10% in 2007(calculated at the end of the fiscal year 2007). The experts predict that the growth ofthe economy of Country X will gradually slowdown in the coming years. Moreprecisely, they foresee the following growth rates for the future:2007 – 2010 = 10%2010 – 2013 = 9%2013 – 2016 = 7.5%2016 – 2019 = 5%2019 – on = 1% Hint: The list above should be read as saying that, for instance, the growth rate fromthe end of the fiscal year 2007 until the end of 2010 will be 10 %, then from the end of2010 until the end of 2013 it will be 9% and so on. Assuming that the predictions of the experts listed above are accurate, when in thefuture will Country X’s GDP double compared to the GDP level of 2007? Consider now the more optimistic scenario in which the economy does not slow downand the current growth rate of 10% remains constant in the coming years. How longwill it take for the GDP level to double in this scenario? Express…Forecasts for Sa’s economic growth rate have been droppingconsistently in 2023, from 1.2% year on year at the start of thefirst quarter to 0.7% in March, 0.6% in April and now 0.4% inthe outcome of the May survey (all Bloomberg).A more recent survey from Reuters in May places the outlookfor economic growth even lower, at 0.2% for 2023.Market perceptions of the global outlook have also dimmed, withChina’s economic recovery proving weaker than anticipatedafter its 2022 lockdowns, as recent production data disappoints,including that on household spending, investment and tradeactivity.Global trade defragmentation is also weakening sentiment, withrisks of limitations on trade competitiveness growing. Theseconcerns, along with US recession fears and disappointment overChina’s ability to lead the global economy stronger in 2023, haveweakened sentiment, reflecting in the recent fall in oil prices.Markets had expected a ramp-up in economic activity in Chinain the second quarter, but has also…

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…Although 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. Discuss the sources of economic growth on the demand side.
- Computing growth rates (II): Suppose k, l, and m grow at constant rates givenby g k, gl , and gm.

What was the average of these growth rates in Econoland over these 5 years? What term would economists use to describe what happened in year 3?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?

What was the average of these growth rates in Econoland over these five years? What term would economists use to describe what happened in year 3? If the growth rate in year 3 had been a positive 2 percent rather than a negative 2 percent, what would have been the average growth rate?Suppose, due to the effects of a military conflict that has ended, that a country experiences a large reduction in its capital stock.
