Suppose that North Korea is a closed economy.
A war breaks out abroad and, as a result, North Korean consumers become uncertain about the future and increase their saving rate.
1) Explain what effect this event would have on the North Korean economy. You do not need to draw the graph, but you do need to describe which curves move and in what direction. No points will be given for answers without an explanation.
2) How would the following variables change as a result of this event?

A new refrigerator is being designed. Magnets will be used to hold the door closed, and the rubber seal thickness can be selected to adjust the separation between the magnets (and therefore the force). The total length of rubber seal required to go around the door is 6m, and the cost of rubber seal is given equation 2. The pull force when opening the door should be 12N. Determine which of the magnet combinations should be used, and the combined cost of the magnets and seals per refrigerator.

A dead body was found within a closed room of a house where the temperature was a constant 70° F. At the time of discovery the core temperature of the body was determined to be 80° F. One hour later a second measurement showed that the core temperature of the body was 75° F. Assume that the time of death corresponds to t = 0 and that the core temperature at that time was 98.6° F. Determine how many hours elapsed before the body was found. [Hint: Let t1 > 0 denote the time that the body was discovered.] (Round your answer to one decimal place.)

One of the big differences between the functioning of a closed versus an open economy is the way fiscal policy affects an economy that fixes its exchange rate. Explain with the aid of charts what those differences are.

Following a closed traverse, the sum of the interior angles was found to vary from the calculated sum by 2 degrees, 30 minutes. The angles were balanced by adding 30 minutes to each of five internal angles. This would be an example of: A. an arbitrarily balanced field angle adjustment. B. mathematical polygon balancing. C. an equally balanced field angle adjustment. D. a poorly conducted traverse.

Consider a simple financial market for a closed economy with government, such as might be crudely representative of the world as a whole. a) Construct a diagram to represent this market and note and explain your choice of the variables on the vertical and horizontal axes.
b) Draw the saving supply curve and the investment demand curve, indicating and explaining which variables shift them to the right and left and why.
c) Imagine that this market faces simultaneous pessimism shocks. There are declines in what level of future income is expected by households and in the net rate of return on new physical capital that is expected by investors. Illustrate and explain how these shocks change the diagram and how you would expect the yield on long maturity assets to change.
d) Then use your diagram to further explain how this result might be affected in the short run by a rise in government spending, and hence a decline in government saving or an increase in sovereign debt.
