- Evaluating the relationship between R&D expenditures and net income is an example of the diagnostic analytics of __________. Multiple Choice determining relations/patterns/linkages between variables through statistical analysis performing drill-down detailed analytics identifying anomalies/outliers performing descriptive analyticsConsider a macroeconomy where the current population is 800 thousand people. Gross domestic private investment is constant $2500 million while consumer expenditure is described by the equation: C = 580+ 0.8DI. The government is fairly active, with a total expenditure of $2000 million and net taxes of $2550 million. Further investigation of the macroeconomy reveals that imports are constant at $3000 million while exports are constant at $2500 million. Currently, the overall price level (GDP deflator) is 118 and the potential GDP level is $13.5 billion. What is the current equilibrium level of real GDP? (report your answer at 2 decimal places and in millions of dollars) 1. What is the current equilibrium level of real GDP 2. what is the current real GDP per capita? 3. what is the value gap?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…

Note: Qda is the quantity demanded for product “a”, Pa is the price of product “a”, Pb is the price of product “b”, Pc is the price of product “c” and Y is the income, ln means natural logarithm. A. the demand for product “a” is price inelastic B. the demand for product “a” is price elastic C. a 1% increase in the Pa will cause a 0.12% decrease in the demand for product “a” D.
