7. Deriving and exploring the total expenditures curve
The following graph shows total production (TP) and the level of Natural Real GDP (NRGDP) for a hypothetical economy. When Real GDP is $325
billion, consumption is $275 billion, government purchases are $50 billion, and investment is $25 billion. When Real GDP is $375 billion, consumption
is $300 billion, government purchases are $50 billion, and investment is $25 billion.
Use the blue line (circle symbol) to plot the economy's total expenditure function within a simplified Keynesian framework.

. In the “complete Keynesian model”, the investment functions was I = I0 - f(i). An analyst now proposes the following investment function: I = I0 - f(i) + qY, where “q” is a parameter and Y is national income = GDP. Provide two different arguments, i.e. explanations as to why this investment function makes sense. The focus is on the new term, qY (q times Y), in the function.
What happens in the simple Keynesian model if households expect lower income in the future and decide to save more today?
Adjust the graph and answer the question.
Assume that investment varies directly with aggregate income.

- Q.1.7 In the Keynesian macroeconomic model, the equation for the savings function is given as: S = -420 + 1/4Y. Based on this information, which of the following statements is correct? (1) The marginal propensity to consume is 1/4; (2) The marginal propensity to save is -420;arrow_forwardExplainarrow_forwardThe consumption and saving functions in the Keynesian model Suppose we observe that a person's disposable income (DI) is 50,000 in 2019 and 63,000 in 2020. Suppose we observe that this person's consumption (C) is 47,000 in 2019 and 58,700 in 2020. Assume that this person's consumption obeys the Keynesian consumption function, so that C = A + MPC*DI. Finally, assume that A and MPC are unchanged between 2019 and 2020. (a) Calculate the values of A and MPC for this consumer, and graph the consumption function. (Hint: subtract the C function in 2019 from the C function of 2020). (b) In general, saving is given by the formula S = DI - C. Calculate this person's saving in 2019 and 2020. Assuming that this person's wealth (net worth) on January 1, 2019 was 80,000, what is their wealth on January 1, 2020? on January 1, 2021? (c) In general, if consumption is given by the function C = A + MPC*DI, then saving will obey the saving function S = -A + (1 - MPC)*DI. Plot the saving function…arrow_forward
