By thoroughly describing and contrasting:

A. The pre world war one gold standard and so-called interwar gold standard between 1919 and 1933/35 and

B.the four major changes that had occurred during WWI and right after that made a return to the the Pre World war one gold standard impossible.

Starting from a long run equilibrium show the short run impact of COVID 19 (short term temporary supply shock) on output and price level graphically and explain the mechanism of these changes. Suppose in the initial long run steady state equilibrium output is 22 trillion dollars and the price level is 100.

“Protein A” is phosphorylated at one amino acid by a kinase, “protein B”, and dephosphorylated by a phosphatase, “protein C”.

You have purified all three of these proteins and want to determine the structural changes that occur when protein A is phosphorylated or dephosphorylated. Explain in detail how you would go about designing and conducting this investigation.

Choices: True or False.

If velocity is zero then acceleration must be zero too.

If speed is constant then acceleration is zero.

If velocity is constant then speed must be constant too.

If speed changes then velocity must change too.

Object slows down if it's acceleration is negative.

If speed is constant then velocity must be constant too.

Who does the demand side of the market represent? Who does the supply side of the market represent? How does movement in the demand curve and the supply curve affect market equilibrium? Your response to the last question should reference the shifts in the supply and demand curves and changes in the equilibrium price and equilibrium quantity.

Studies indicate that net exports and net capital outflows tend to be equal.

a) Why do net exports and net capital outflows tend to be equal? How does an increase in the price level change interest rates?

b) How does this change in interest rates lead to changes in investment and net exports?

A bond with a $1,000 par, 6 years to maturity, a coupon rate of 4%, and annual payments has a yield to maturity of 3.6%. What will be the actual percentage change in the bond price if the yield changes instantaneously to 4.3%? Round to the nearest 0.001%, drop the % symbol (e.g., if your answer is, e.g., 1.1234%, enter it as 1.123.)

A project that costs $3000 to iinstall will provide annual cash flows of $800 for each of the next 6 years. The firm accepts projects with a discounted payback of 5 years or less. Should this project be pursued if the discount rate is 2%? What if the discount rate is 12%? Will the firm's decision change as the discount rate changes?
