Explain and illustrate how the central bank from country A would react, everything else held constant. For simplicity, assume no time lag for policy to affect the economy, the economy is starting at potential output, and country B is a major trading partner.

Country B makes it harder for country A's investments to buy B's stock.

To illustrate that change, plot NCO and NX on one graph, and AE on the second graph. For your analysis, choose as a starting point (marked A), an economy operating at potential GDP (Y1=Y*). Mark initial curves as NCO1, NX1, and AE1, and every subsequent shift with a higher number, like NCO2, NX2, and AE2 and so on, and any subsequent point as B, C, D and so on (points need to be on both graphs).

There is a decrease in demand for country A's goods by the consumers of country B.

The study of economics is comprised of three general areas: microeconomics, macroeconomics, and econometrics. What is econometrics? Provide a comprehensive definition of econometrics. IB. What are the two general uses of econometric models? List and briefly discuss both of these. IC. The multiple linear regression model was argued, in general, to be superior to the uni-variate linear regression model for two reasons. Considering your response to IB, discuss the two reasons the multiple regression model is superior.The table below shows the distribution of each instruction type on a processor running with a 2 GHz clock frequency. Instr Proportion CPI (baseline) CPI (opt #1) CPI (opt #2) Load/Store 24% 5 2 3 Branch 30% Mul/Div 12% Other 34% Total 100% Question 3.A Baseline CPI (4 points) What is the average CPI of the baseline processor? Question 3.B Optimization (6 points) With some optimization, and the support of some extra logic, the microarchitecture can decrease the load and store CPI to 2 and branch CPI to 1 and decrease the mul/div logic to a CPI of 7 (option #1). Alternatively, the extra logic that can be spent can be used to optimize load and store CPI to 3 and the mul/div logic to support CPI of 1 (option #2). What is the CPI speedup of each optimization relative to the baseline design? Which optimization is better to improve performance
