Midterm Cancellation and Paper Assignment: Econ 115, Fall 2009

I really do not want to give up November 19 as a lecture day--and bitter experience has taught me that an afternoon lecture on the Tuesday before Thanksgiving, the 24th, simply does not work.

Therefore: the midterm scheduled for November 19 is cancelled.

In its place is substituted:

Due Friday December 11, 5 PM: 2500 words. Take one of your short papers for this course--I hope the one you liked most--and expand it and its argument to about 2500 words.

This assignment substitutes for the November 19 midterm in all respects.

Midterm 2, Part III Answers

1. Government spending must be increased by an amount x, such that x*1.5 = 10 percent. Thus x = 10/1.5 = 6.67 percent. 

2. 6.67 percent of 14 trillion is (roughly) 900 billion. (1 trillion was also a perfectly acceptable answer.)

3. Very low. 

4. Different answers possible.

No calculators allowed, You won’t need them. All you will need is simple arithmetic (the ability to multiply things by two, and to divide) and the rule of 72—the fact that a quantity growing at 1% per year doubles in 72 years, a quantity growing at 2% per year doubles in 36 years, a quantity growing at 0.5% per year doubles in 144 years, et cetera, a quantity growing at 1% per year grows by 41.41% in 36 years, etc…

PART 3 (25 MINUTES): Calculations

Consider the 144 years between 1866 and 2010…

1. World population grew from about 1.1 billion to 6.4 billion. About how many doublings did population undergo? What is the average growth rate of world population over those 144 years?
2. World total real GDP (on one somewhat arbitrary set of assumptions, at least) grew from $875 billion of today’s dollars in 1866 to $56 trillion of today’s dollars today. What was the average growth rate of world total real GDP over those 144 years?
3. If world total real GDP growth continues to grow at its average 1866-2010 rate, what will world total real GDP (in today’s dollars) be in 2155? Do you think this is possible? Reasonable? Absurd? Why?
4. By contrast, total world GDP (on one somewhat arbitrary set of assumptions, at least) grew from $437.5 billion of today’s dollars in 1794 to $875 billion of today’s dollars in 1866. Suppose total world real GDP growth had continued at its 1794-1866 pace from 1866-2010. What would total world real GDP be today?
