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 the economies of Hermes and Gobbledigook, both of which produce gobs of goo using only tools and workers. Suppose that, during the course of 20 years, the level of physical capital per worker rises by 4 tools per worker in each economy, but the size of each labour force remains the same.
first dropdown question options are (larger or smaller), second dropdown question options are (the brain drain, inward orietned growth, diminishing returns, constant returns, increasing returns), the third dropdown question oprions are (more diffucult or easier)
Consider the simple innovation model studied in class.
In this model, the society allocates a fraction "gamma" of workforce to innovation and the remaining fraction to production. Suppose that, for
simplicity, total workforce is normalized to unity: L = 1.
If the productivity growth rate is defined by
d A t/dt = "theta"* "gamma" * A_t
and real GDP per worker by
yt = At* (1 - "gamma"),
what is the long-run growth rate of y_t?

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.

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?

- Suppose that the annual rates of growth of real GDP of Econoland over a five-year period were sequentially as follows: 3 percent, 1 percent, −2 percent, 4 percent, and 5 percent. 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?arrow_forwardConsider the economies of Hermes and Gribinez, both of which produce gaggles of gop using only tools and workers. Suppose that, during the course of 10 years, the level of physical capital per worker rises by 5 tools per worker in each economy, but the size of each labor force remains the same. Complete the following tables by entering productivity (in terms of output per worker) for each economy in 2016 and 2026. **THE TABLE IS ATTACHED** Initially, the number of tools per worker was higher in Hermes than in Gribinez. From 2016 to 2026, capital per worker rises by 5 units in each country. The 5-unit change in capital per worker causes productivity in Hermes to rise by a _________ (LARGER/SMALLER) amount than productivity in Gribinez. This illustrates the _______ (CATCH-UP/NATURAL RESOURCES/TECHNOLOGY/HUMAN CAPITAL) effect. THANK YOU FOR THE HELParrow_forwardThe economy of Ghana is made up of three sectors namely: Agriculture, Industry and Services. These three sectors contribute to the national output. For decades, prior to the 2000s, the Agricultural sector contributed the most to the national output. Sadly, in recent years however, the sector has been the least contributor to national output. Trends in production of major food crops such as maize, rice and sorghum show that on-farm productivity has stagnated and the exploitable difference between the actual and the potential output of most of the crops (yield gap) has widened. Low and inadequate levels of usage of productivity enhancing technologies such as quality seeds of improved varieties and fertilizer, inadequate extension services and weak market linkages contribute to the poor agricultural performance. It was against this background that the NPP-led government implemented one of her flagship programmes “Planting for Food and Jobs”. The programme is primarily aimed at making…arrow_forward

Then find the steady-state levelof income per worker and steady-state level of consumption per worker. c) Is it possible to save too much? Why?arrow_forwardCountry A and country B both have the production function Y = F(K, L) = K^0,5L^0,5 A. Does this production function have constant returns to scale? Explain. B. What is the per-worker production function, y = f(k)? C. Assume that neither country experiences population growth or technological progress and that 5 percent of capital depreciates each year. Assume further that country A saves 10 percent of output each year and country B saves 20 percent of output each year. Using your answer from part (b) and the steady-state condition that investment equals depreciation, find the steady-state level of capital per worker for each country. Theen find the steady-state levels of income per worker and consumption per worker. D. 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 a computer spreadsheet…arrow_forwardExplain, using the OLG model, how an increase in the growth rate of technology affects welfare - specifically, argue how the intertemporal discount rate may change in response to an increase in technological growth and .
