Briefly describe the two conclusions that can be drawn from an overview of Say’s Law with its emphasis on macroeconomic supply and Keynes’ Law with its emphasis on macroeconomic demand.

A large open economy has desired national saving of Sd = 1200 + 1000 rw, and desired national investment of Id = 1000 - 500 rw. The foreign economy has desired national saving of Sdfor = 1300 + 1000 rw, and desired national investment of Idfor= 1800 - 500 rw. The equilibrium world real interest rate equals a. 0.05. b. 0.10. c. 0.15. d. 0.20

Do you believe that the Hayek’s classical AD-AS model explain the factors that cause changes (shifts) in AS realistically? Why or why not?

Legislation proposes that the government should use macroeconomic policy to achieve an unemployment rate of zero percent, by increasing aggregate demand for as much and as long as necessary to accomplish this goal. From a neoclassical perspective, how will this policy affect output and the price level in the short run and in the long run? Sketch an aggregate demand/aggregate supply diagram to illustrate your answer.

A friend of yours (who has not taken macroeconomics) has just read that Keynesian theory represented a direct attack on Classical theory. They don't understand either theory and knows you (having just taken macroeconomics) are well-versed in both. They ask you to explain the basic differences between how Keynes and the Classics understood the business cycle and their respective policy prescriptions. Your answer should probably include: a) a basic explanation of what full-employment GDP means and how it relates to the stability condition S=| (or, equivalently, leakages = injections); b) an explanation of why the Classicals believed that any movement away from full-employment GDP would be quickly fixed/reversed; c) an explanation of why Keynes thought the Classicals* "auto-correcting" story was problematic, i.e., a detailed explanation of Keynes' multiplier concept (how did Keynes believe a recession would unfold (step-by-step) and why did he believe it could persist); d) an explanation…

What is the shape of a typical Hubbert Curve?

thanks in advance

Suppose we have the following information for the simple (fixed r, fixed P, fixed W) Keynesian model.               C = 400 + 0.8                                            I = 310                                                                               G = 140                = 400 + 0.8 (Y - T)                                T = 200,               where C is the consumption function, (Y - T)  is disposable income, I is investment, G is government spending, and T is taxes. What is equilibrium income ($output), Ye ? Group of answer choices A) $5,050 B) $3,450 C) $6,900 D) $2,050 E) $5,450

Contrast Say’s law with Keynes Law, do they provide completely different interpretations of macroeconomic behavior? Provide examples

A neoclassical economist and a Keynesian economist are studying the economy of Vineland. It appears that Vineland is beginning to experience a mild recession with a decrease in aggregate demand. Which of these two economists would likely advocate that the government of Vineland take active measures to reverse this decline in aggregate demand? Why?
