- Suppose that the current (fifi rst) generation consists of 1 million people, half of whom are women. If the total fertility rate is 1.3 and the only way people die is of old age, how big will the fourth generation (the great-grandchildren) be? How much smaller (in percentage terms) is each generation than the previous generation? How much smaller (in percentage terms) is the fourth generation than the fifirst generation? Are you surprised by how quickly the population declines?hy does a measure of labor productivity—the output produced per worker– rise for many firms during recessions? During the boom years period of 2005through November 2007, the annual average output per worker was lower in U.S.manufacturing than during the Great Recession of 2007–2009 as well during therelatively low-demand years since then through 2013.Firms produce less output during recessions as demand for their products falls.Consequently, firms typically lay off workers during recessions. Thus, whetheroutput per worker rises or falls depends on whether output or employment fallsby more. The labor productivity pattern over the business cycle differs across in-dustries. If we know about a firm’s production process, can we predict whetheroutput produced per worker will rise or fall with each additional layoff?Suppose you observe over the last 15 years that the percentage growthin output was 25%, percentage growth in capital was 10%, and percentagechange in labor was 20%. Assume elasticity of output with respect to capitalis 0.4 and elasticity of output with respect to labor is 0.6. Calculate thecontributions to output growth from capital and labor, and then solve forproductivity growth. Please show equation throughout the whole process
- Assume that a business firm finds that its profit is greatest when it produces $40 worth of product A. Suppose also that each of the three techniques shown in the table below will produce the desired output:a. With the resource prices shown, which technique will the firm choose? Why? Will production using that technique entail profifit or loss? What will be the amount of that profifit or loss? Will the industry expand or contract? When will that expansion or contraction end?b. Assume now that a new technique, technique 4, is developed. It combines 2 units of labor, 2 of land, 6 of capital, and 3 of entrepreneurial ability. In view of the resource prices in the table, will the fifi rm adopt the new technique? Explain your answer.c. Suppose that an increase in the labor supply causes the price of labor to fall to $1.50 per unit, all other resource prices remaining unchanged. Which technique will the producer now choose?

- Please no written by hand Suppose that in a country one-third of all females born die in infancy, one-third of all females die in infancy, one-third die at age 30, and one-third live to age 60. Women bear one child at age 25, one child at 28, one child at age 32, and one child at age 35. One-half of children are girls. b.) Suppose the mortality is reduced so that there is no infant mortality. Half of all women die at age 30 and a half at age 60. Compute the NRR.Let us assume that four plots of land is currently used for agriculture which are denoted as A,B,C and D where A is the most productive land while D is the least productive land (marginal land). Suppose that the profit rate of land D is 10%. a) What the investors of that country are expected to do in that case if the profit rate in industry is 12% according to Ricardo? Will the D continue to be the marginal land in that case? b) What the investors of that country are expected to do in that case if the profit rate of industry is 8%? Do this lead to a change in what will be the marginal land in that case?One of your clients, a mining company with operations in the Democratic Republic of Congo and Zambia, is concerned withthe current macroeconomic environment’s impact on their operations. Among their worries is the slowdown in global growth, which is expected to moderate from 5.9 in 2021 to 4.4 percent in 2022—half a percentage point lower for 2022 than in the October World Economic Outlook.You are required to critically discuss some of the major factors that drove the global growth trajectoryi) Pre-Covid-19 pandemic ii) at the height of the pandemic iii) going into 2022 and beyond.
- Show that, when using a traditional economic production function,doubling our population can double our output if capital stocks alsodouble. Use the production function: Q = AK L , where A representstechnology in an economy, K capital, and L labor. Double K and L andshow that Q also doubles, assuming α=β=1/2. Now show that, when we incorporate natural capital into thediscussion, doubling the population does not increase output in thesame way (since natural capital cannot also grow). Use theproduction function: Q = AK L N , where N is natural capital. DoubleK and L and show that Q less than doubles, assuming α=β=γ=1/3.In the United States, labor earnings are about what percent of total income?

Rest assured, you will receive an upvote if the answer is accurate.Consider the U.S. during the Great Depression and WWII –fertility rates were low (between 1929 and 1945 total fertility rate (TFR) was about 2.5 per woman aged 15-44). a.What does a fertility rate of 2.5 per woman mean? Through the 1960s, the U.S. saw a baby boom (TFR of 3.4 between 1946 and 1964). However, since 1980 the TFR has fallen below 2.1. b.What may explain the fall in fertility after the 1980s? c.Even though the fertility rate fell to replacement rate in 1980, population was still growing in the U.S. during the 1980s.
