What impact is the COVID crisis having on the global economy? How long will it last? What are the current policy responses around the world and how effective will they be?

Below is a short video from the respected weekly magazine "The Economist" and a link to a Harvard panel on this topic. Please watch these videos and share your thoughts.

8) Answer all three parts: (a) Why has inequality increased over the last 50 years and why does it continue to increase? Is there a logical end point to this or are we headed back towards a period when the world had a handful of aristocrats and their workers/peasants/servants? (b) Do you consider income and wealth inequality to be a problem in the world today? If so, what do you think can be done about it? If you don't think growing inequality is a problem, explain why. (c) Can unions play a role in reducing inequality? How?

Ryan likes to listen to music while studying at home. His brother Isaac, however, needs peace and quiet in which to work. They both get an allowance and so have some money. To deal with arguments over whether music is played or not the parents decide that on Monday, Wednesday, Friday and Sunday peace and quiet must reign, but that on Tuesday, Thursday and Saturday it’s ok to play music. Note that the parents set this rule just to avoid quarrels between the two brothers; hence they do not need to stick to the rule as long as there is no quarrel. Note further that no headphones are allowed. Isaac values peace and quiet at $10 per day. Ryan values the ability to play music at $7 per day. If the boys are allowed to negotiate between themselves on which day(s) does music get played? Explain.

Explain the various perspectives one can have on public budgeting and how each perspective can affect the definition of public budgeting. What should this mean to you as a person putting together a government budget?

Suppose Potential GDP is $15 trillion. Further suppose that the short-run aggregate supply (SRAS) curve intersects the aggregate demand (AD) curve at a level of Real GDP of $18 trillion and a Price Level of 120 as measured by a price index

a. Draw the Aggregate Demand – Supply Graph for this situation. (Call this point A).

b. Is there an inflationary or a recessionary gap?

c. Assuming no fiscal policy is used, show the long run equilibrium by completing this graph. Show this long run result due to this short run macroeconomic situation in part b. (Call this point B).

d. Will nominal wages change between points A and B? Will they rise, fall, or stay the same?

e. For this question draw a separate graph (drawing the situation in part A of this question). Suppose that instead of the economy self adjusting, the correct fiscal policy in this situation is used. Complete the graph showing the new long run equilibrium after the correct fiscal policy is used in this situation.

1. With the aid of an example, explain how product differentiation can act as an entry barrier and influence a firm’s demand in monopolistic competition?        
2. Monopolistic competition is sometimes criticized for displaying excess capacity. Using a fully labelled diagram, explain how product diffrerenciation can lead to excess capacity in long run equilbrium.                                                                        
3. With reference to your answer in a) and b) above, evaluate whether excess capacity is good or bad for society.

The Tree Top Airline (TTA) is a small feeder-freight line started with very limited capital to serve the independent petroleum operators in the arid Southwest. All of its planes are identical, although they are pointed different colors. TTA has been contracting its plane overhaul work to Alamo Airmotive for $63,000 per plane per year. TTA estimates that, by building a $200,000 maintenance facility with a life of 6 years and a residual (market) value of $35,000 at the end of its life, they could handle their own overhaul at the cost of only $39,000 per plane per year. What is the minimum number of planes that they must operate to make it economically feasible to build this facility? The MARR is 27 % per year. (Enter your answer as a number without the dollar $ sign.)

Question 1
The core elements of the Growth Employment and Redistribution (GEAR) strategy of the South African government in 1996, under the leadership of the then finance minister Trevor Manuel were amongst other things:
i) budget reform to strengthen the redistributive thrust of expenditure
ii) monetary policy to prevent a resurgence of inflation
iii) a reduction in tariffs to contain input prices and facilitate industrial restructuring, compensating partially for the exchange rate depreciation

1.1 With reference to the above, identify the macroeconomic objectives in these elements.
1.2 Identify and define the macroeconomic variables that can be used to measure whether the strategy was successful or not.
1.3 With each tool in 1.2, provide a detailed explanation on how it can be measured.
