- Jack and Jill both obey the two-period Fisher model of consumption. Jack earns $200 in the first period and $200 in the second period. Jill earns nothing in the first period and $410 in the second period. Both of them can borrow or lend at the interest rate r. a. You observe both Jack and Jill consuming $200 in the first period and $200 in the second period. What is the interest rate r? b. Suppose the interest rate increases. What will happen to Jack’s consumption in the first period? Is Jack better off or worse off than before the interest rate rise? c. What will happen to Jill’s consumption in the first period when the interest rate increases? Is Jill better off or worse off than before the interest rate increase?Nick and Steve both obey the two-period Fisher model of consumption. Nick earns $300 in the first period and $300 in the second period. Steve earns nothing in the first period and $620 in the second period. Both of them can borrow or lend at the interest rate r. Nick and Steve both consume $200 in the first period and $200 in the second period. What is the interest rate r?In the context of the Irving Fisher two-period model, if a person is a saver (i.e., C1 < Y1), a fall inthe real interest rate causes: (a) C1 to rise; C2 to fall(b) C1 ambiguous; C2 to fall(c) C1 to fall; C2 ambiguous(d) C1 to fall; C2 to rise
- Consider the intertemporal model of consumption studied in class, with two possible periods. Consider initially that an individual is a borrower. If the interest rate increases: (a)The individual will never become a saver. (b)The individual will always remain a borrower. (c)The individual will be worse off, provided she remains a borrower. (d)The individual can be better off, but only if she becomes a saver. Both c and d.Elaborate on how one or more of the microeconomic components, namely consumption, investment, supply and demand for money influence macroeconomic outcomes and formulations of the following macroeconomic theories: Solow Growth Model The Mundell-Fleming model Neoclassical Model of Investment Use mathematical equations and graphs where necessary.The Clark-Fisher model explains the significant shift within the economy over time by emphasizing: a. The breakthroughs in Artificial Intelligence (AI) and Machine Learning (ML) systems. b. Mechanization, modernization, and Automation (MMA). c. The movement of labor force from high productivity sectors to low productivity sectors. d. The movement of labor force from low productivity sectors to high productivity sectors.
- Question : Fisher's two period model implies that as long as consumption in both periods is as a normal good, then an increase in income in period two: a- increases consumption in period 1 only. b-increases consumption in period 2 only. c. does not increas consumption in either period. d. increases consumption in both periods. e. increases consumption in period 1 and reduce consumption in period.In January 2017, a report from the National Retail Federation said that “Holiday retail sales during November and December increased 4 percent over 2015 to $658.3 billion.” The NRF’s chief economist “noted that average hourly earnings were up in 2016 over 2015 … home values have also increased and the rising stock market has increased the value of consumers’ investments.” Which models of consumption behavior was the economist referring to? Precautionary savings model and Friedman’s permanent income model Keynesian consumption model and Modigliani’s life cycle model. Inventory cycle model and Modigliani’s life cycle model. Keynesian consumption model and precautionary savings model.Piketty (2014) argues that a fall in the growth rate of the economy is likely to lead to an increase in the difference between the real interest rate and the growth rate. This problem asks you to investigate this issue in the context of the Ramsey Cass Koopmans model. Specifically, consider a Ramsey Cass Koopmans economy that is on its balanced growth path, and suppose there is a permanent fall in g. (a) How, if at all, does this affect the k = 0 curve? (b) How, if at all, does this affect the c = 0 curve? (c) At the time of the change, does c rise, fall, or stay the same, or is it not possible to tell? (d) At the time of the change, does r - g rise, fall, or stay the same, or is it not possible to tell?
- Briefly explain how one or more of the microeconomic components, namely consumption,investment, supply and demand for money influence macroeconomic outcomes and formulations of the following macroeconomic theories:a. Solow Growth Model b. The Mundell-Fleming model c. Neoclassical Model of Investment Use mathematical equations and graphs where necessary.The following Mundell-Fleming model of a small, open economy will be used in all numerical exercises. It assumes a short-run framework in which prices are constant and output is demand-determined. C = 200 + 0.8(Y − T) I = 500 − 30r NX = 10 − 100e M/P = 50 + Y − 60r r = 2 G = 200 T = 100 M = 4000 P = 2 a.)Suppose that households become less confident about the future and reduce their autonomous level of consumption from 200 to 150. Solve for the new values of e, Y and NX. With the help of graphs, explain very carefully the mechanisms by which a new equilibrium is reached. b.) Suppose that with all exogenous variables at their original values, the autonomous part of money demand increases to 70. Solve for the new values of e, Y and NX. With the help of graphs, explain very carefully the mechanisms by which a new equilibrium is reached. c.) Based on your answers to parts (a) and (b), evaluate the role of floating rates as automatic stabilisers when exogenous shocks hit the economy.Let’s analyze the rational behavior and well-being of 3 different individuals in regards to their saving and borrowing behavior. I recommend drawing the intertemporal consumption model graph for each of the following situations. We will be analyzing three individuals; Charlie is saving at the current interest rate, Allison is borrowing at the current interest rate, and Chris is neither saving nor borrowing at the current interest rate. (a) Charlie is currently saving money (spending less than his current income) at the current interest rate. Will he be made better off if the interest rate subsequently increases? (b) Allison is currently borrowing money (spending more than her current income) at the current interest rate. Will she be made better off if the interest rate subsequently increases? (c) Chris is currently neither saving nor borrowing (spending exactly his current income) at the current interest rate. Will he be made better off if the interest rate subsequently increases?…
