What is the Euler equation for consumption, and what is its economicinterpretation?
Linear equations for the consumption and saving schedules take the general form C = a + bY and S = -a + (1 - b)Y, where C, S, and Y are consumption, saving, and national income, respectively. The constant a represents the vertical intercept, and b represents the slope of the consumption schedule.a. Use the following data to substitute numerical values for a and b in the consumption and saving equations. b. What is the economic meaning of b? Of (1 - b)? c. Suppose that the amount of saving that occurs at each level of national income falls by $20 but that the values of b and (1 - b) remain unchanged. Restate the saving and consumption equations for the new numerical values, and cite a factor that might have caused the change.

Consider a national income model as: Y= C + I0 + G Y= National Income C= (Planned) Consumption Expenditure I0= Investment G= Government Expenditure Consider Y= 20trillion, G= 4.2trillion, I0= 3.8 trillion. Explain the key elements missing from the National Income model. Add a new endogenous variable to represent that missing element or endogenize one of the exogenous variables to address this issue. C= a+ b(Y-T0) (a>0, 0<b<1) G= gY (0<g<1)
Consider a simple macro model with a constant price level and demand determined output. The equations of the model are c=90+0.36y I=155 G=290’T=125 and IM=0.06Y. A national income of 1100 results in desired aggregate expenditure of…
Suppose an economy produces only 2 products that will also be used for directconsumption, as per the article at the end of the exam: chicken wings and donuts. Inthe second quarter of 2021 (the base period), 180,000 pounds of chicken wings wereproduced, at a value of $3.50 per pound, while in the second quarter of 2022,production of chicken wings increased to 200,000 pounds, at a value of $3.75 perpound. In the second quarter of 2021 (the base period), 85,000 donuts were producedat a value of $0.85 per donut, while in the second quarter of 2022, donut productionincreased to 100,000 donuts, each at a value of $0.95 per donut. The population inthis economy is 1000 individuals in 2022, while the number of hours worked in 2022is 5000. Also, the quantities that were produced in 2021 represent the quantities thatwere purchased by the typical household, meaning that everything that was producedwas sold.d. Solve for the amount of labor productivity in the second quarter of 2022.e. Solve for the…
Assume that the average or mean monthly household consumption expenditure for Malaysia rose from RM3,578 in 2018 to RM4,033 in 2020, growing 6% per annum at nominal value, according to the statistics department. However, in terms of real value — which refers to the constant price using the Consumer Price Index with the base year 2014 as the deflator — annual growth rate is 3.9% for the same period, mentioned on its Household Expenditure Survey Report 2020. a) Suppose that consumer spending initially rises by RM5 billion for every 1 percent rise in household wealth and that investment spending initially rises by RM20 billion for every 1 percentage point fall in the real interest rate. Also, assume that the economy’s multiplier is 4. i. If household wealth falls by 5 percent because of declining house values, and the real interest rate falls by two percentage points, in what direction and by how much will the aggregate demand curve initially shift at each price level? ii. In what…
