- Consider a one-period economy which experiences the destruction of some of the nation’s capital stock (say through a hurricane is de- stroyed). How should this effect equilibrium, consumption, output and labor supply? Now, let’s say the government tries to offset some of the declines in capital on output and hours worked by increasing govern- ment spending. What is the likely outcome of this policy intervention in terms of consumption? In our model, the affects of changes on wages are ambiguous because the income and substitution effects move in opposite directions. How do (many) macroeconomists deal with this ambiguity in terms of study- ing business cycle? How do economists resolve this ambiguity when studying long term economic development? Consider an economy with a straight line PPF. Show how an increase in government spending paid for by an increase in lump sum labor taxes affects outcomes. Do the same for an increase in government spending financed by a proportional income…A positive oil shock: Suppose scientists discover a new way to extract oil fromdeposits that were previously thought to be unrecoverable. Te extra supply ofoil leads oil prices to decline by $5 per barrel. Explain the efect on wages, theemployment-population ratio, and unemployment—all for the overall economy.A country has two regions, the North and the South, which are identical in all respects except the hourly wage and the number of workers. The demand for labor in each region iswN = $20 - .5EN and wS = $20 - .5ESwhere EN and ES are millions of workers. Currently there are 6 million workers in the North and 18 million workers in the South.a. What is the wage in each region?b. If there are no shocks to the economy, migration over time will result in an equalization of wages and employment. What would be the long-run wage and employment level in each region?c. Return to the original setup where there are 6 million workers in the North and 18 million workers in the South. As a policymaker, you decide not only to allow 2 million immigrants of working age to enter your country, but you have the authority to resettle the immigrants wherever you want. How should you distribute immigrants across the regions to maximize the country’s immigration surplus? Besides maximizing the immigration surplus…
- Using AD-AS analysis show graphically and explain the effect on the equilibrium level of price and income if: Increase in productivity of labour after attending the intensive course from their company. National per capita income has increased from RM40,713 in 2018 to RM42,777 in 2019. Dear experts, please explain me each of it seperately with full explanation so I could understand it better. Thanks in advadnce."The more sluggish wage and price adjustment is, the more variable output and price level are when an activist policy is pursued " is this statement ture, false, or uncertain? explain your answerWhen wage rates rise slower than the increase in labour productivity, the OA. output gap increasesOB. output gap fallsOC.

- Changes in macroeconomic indicators can often be of relevance to business decision-making. For instance, changes in macroeconomic performance reflected in indicators can impact things such as firms profit forecasts, expected sales growth, expansion plans, etc.Assume you are employed as a business analyst with the large Australian based mining company. Identify and discuss how each of thefollowing macroeconomic issues may be relevant to the firm:a) A world-wide economic slow-down.b) Appreciation of the Australian dollar relative to other major currencies.c) The government abolishes subsidies to the mining industry.In a country called Uncle Sam Land (USL), the labor demand curve is given by:W = K- 4LWhere W is the wage rate, K is a variabledetermined by accumulated capital stock in thecountry, and L is the labor force in the country.K= 50 is supplied by the capitalists.If the labor force in this country goes up from 10 to 11, what happens to the national income in USL?National Income = income of all workers + income of all capitalists.Select one:a. Does not changeb. Goes down by 44c. Goes up by 8d. Goes up by 26e. None of the above.Consider an economy in which the marginal product of labour is given by MPN = A(150 − N), where N is the amount of labor used. The amount of labour supplied is given by 60 + 5(1 − t)w, where w is the real wage and t is the tax rate on labour income. (a) Suppose A = 2 and t = 20%. Calculate the equilibrium levels of real wage and employment. (b) Suppose that the economy experiences an adverse supply shock and A = 1. Everything else remains the same as before. Calculate the equilibrium levels of real wage and employment in this case. (c) Suppose that the government lowers the labour income tax by 50% following the adverse supply shock, i.e., A = 1 and t = 10%. Calculate the equilibrium levels of real wage and employment in this case. (d) Use the labour market diagram to illustrate the adjustments from the original equilibrium in part (a) to the equilibrium in part (b) and then the adjustments from the equilibrium in part (b) to the equilibrium in part (c). Explain the adjustments from…
- 1. An economy's firms produce goods along the Cobb-Douglas production function: Y = A * K^0.5 * L^0.5 For it, the marginal product of a worker is MPL = 0.5 * A * K^0.5 / L^0.5, in which K = 16 Workers bargain for wage by looking at the rate of unemployment and inflationary surpise: w = 2 * EP/P *L^0.5 K = 16. The economy is in equilibrium at EP=P=1 and A=9. In it, the number of workers is L=9 and the wage is =6. Now, thanks to temporarily abundant oil, the productivity changed from A=9 to A=16. Find the new equilibrium number of workers. 2. Find the new equilibrium wage at A=16. 3. Graph the change in the labor market equilibrium. Mark the before and after equilibria with E0 and E1. Label axes and curves, map relevant values onto axes.Please only awnser this question I must give uou the previous question below it for context Please awnser this one: In the same model of the labour market as in the previous question,Select one or more:a. A rise in labour supply will lead to a rise in wagesb. Given a constant mark-up a rise in labour productivity will lead to higher wagesc. A rise in product market competition will lead to a higher mark-upd. Equilibrium employment is given by the intersection of the wage and profit curves This one is just for context so you can awnser the question: Given labour market equilibrium with identical workers, as set out in CORESelect one or more:a. Unemployment is always voluntaryb. Workers who are involuntarily unemployed cannot gain a job at any wagec. A Nash equilibrium existsd. Measured unemployment will be zeroThe IS-LM model is a simplification of the interrelationship between selected economic variables. The model consists of a number of en- dogenous variables (those variables whose values are determined inside the model) and a number of exogenous variables (those variables whose values are determined outside the model). The labour markets mostly consider the relationships between prices, expected prices, unemploy- ment among other macroeconomic variables. (a) Explain endogenous and exogenous variables in the IS-LM model as well as the labour markets, derive the AD-AS model.
