- 30. Given this model, what would be the change in equilibrium level of income were G to increase to 250? 31. Given this model, what would be the new equi8librium level of income were Investment spending to decline by 50?The firm you work for wants you to provide some insight into the investment environment in Mexico before deciding to enter the market. You conduct some research and find a large dispersion of MRPK across firms in Mexico. You also notice that state-owned firms have lower MRPK. Which of the following observations can you make? (there can be more than 1) Firms in Mexico have a hard time expanding due to constraints on the labor market Private firms are at an advantage in Mexico as they face lower capital costs than those owned by the state Resources are likely misallocated because capital is not flowing from firms with low MRPK to firms with high MRPK Your firm may find it more costly to borrow than its state-owned competitorsRefer to Figure 1. Injections = leakagesA) when income = zero.B) when consumption = saving.C) at equilibrium.D) when output = investment.
- You are given data on the following variables in an economy: Government spending 300 Planned investment 200 Net exports 50 Autonomous taxes 250 Income tax rate 0.1 Marginal propensity to consume 0.5 Use the data above to answer the following questions. Consumption (C) is 600 when income (Y) is equal to 1500. Solve for autonomousconsumption. Solve for the equilibrium level of output in the following two scenarios: there isan income tax t=0.1, there is no income tax in the economy. Denote these two variablesby and respectively.

Assume that we can view this as a negative shock to private investment, due to a combination of lockdowns and uncertainty about the world. In under 150 words, answer the following question: Was government consumption expenditure used as stabilisation policy following the slow-down during 2020 and 2021?

- Consider an economy that works acoording to the classical model, and the Fisher equation holds for the money market. In this economy the consumption function is C(Y-T)=250+0.75(Y-T), the investment function is I(r)=1000-50r, where Y is income, T is net taxes and r is real interest rate. The government spends 1100 units of output on goods and services and coolects 1000 units as taxes. The labor supply is 1000, while the capital stock is 2500 units. The production function of this economy can be described as Y=K0.5L0.5. The economy is in its long-run equilibrium. The velocity of money is 2, while nominal supply of money is 6000. a) Calculate the equilibrium interest rate of this economy. b) Calculate the price level. c) What is the real wage at which the labor market is at equilibrium? What is the nominal wage? Plzzz give answer of all questions.1. Induced consumption is: (a) the part of consumption which is independent of the level of income.(b) the minimum level of consumption that is financed from sources otherthan income.(c) The maximum level of consumption that is financed from sources otherthan income.(d) shown by the slope of the consumption function.2. In the Keynesian model, an introduction of a proportional tax will: (a) increase the slope of the consumption function.(b) reduce the multiplier.(c) increase the equilibrium level of income.(d) increase the multiplier.3. A decrease in the price level will: (a) shift the AS curve to the left.(b) shift the AD curve to the left.(c) shift the AS curve to the right.(d) leave both the AD curve and the AS curve unchanged.Consider the following model of an economy operating with fixed wages, prices and interest rates and hasexcess capacity. Adsume all figures are I Zambian kwacha. C=100+0.8yd, T=100+25Y, G=980 and I= 500 Where c is consumption, yd is disposable income, T is taxes net of transformers, G is government spending on goods and services and I is investments. A. Calculate the equilibrium level of national income B. Illustrate your equilibrium in the keyneasian cross diagran C. What is the value of the multiplier D. Is governnent running a surplus or a deficit E. Show the impact of a reduction in government spending by 80 on the equilibrium level of national income F.
