(b) Given that nothing else is borrowed in the near future, the length of time it will take a government to completely eliminate its stock of debt will be entirely dependent on how much more annual repayments exceed the annual interest expenses. The interest expense portion of the debt is a function of the present stock of debt, y, and is given by i(y) = y – y² The amount of money that the government repays to reduce its debt stock is assumed to be a fraction, a, of the present stock of debt. Repayment is done at the end of each financial year. (i) (ii) Solve for the present stock of debt, y, as a function of t. What will happen to government debt as t → ∞? Justify your response.

1. Over a period of 10,000 years, the population of Brobdingnag is estimated to have increased from 4 million to 170 million. Assuming that the level of income per worker was constant, there are only two factors of production, Land (X) and Labour (L), and the exponent on land in the production function is one-third, what was the annual growth rate of productivity, A? a) 0.17% b) 0.42% c) 0.03% d) 0.01%

The economic activity of a country is often quantified as the gross domestic product (GDP), which is the sum of private and government consumption, investments, and net exports (the value of exports minus the value of imports). For a developed country such as the United States, economists might see a GDP growth rate of 3% a year as reasonable. However, production and consumption create some pollution. By how much would pollution per dollar of GDP have to decline for pollution levels 50 years from now to be the same as current levels, assuming a 3% annual growth rate of GDP? In 75 years? In 100 years? (Hint: Let the current pollution level be 1 and find out what the future pollution level would be).
Common Property and Public Goods Problem To water their vine yards, a group of farmers in Cyprus drill identical wells and draw irrigation water from an underground aquifer. This aquifer has a natural maximum recharge rate of 340,000 liters per day (in others words, a maximum of 340,000 liters of water per day filter into this underground reservoir from natural sources). The table below shows the relationship between the daily total water output (total product) and the number of wells operating. Number of Wells Operating Total Water Output (in 1000s of Liters/Day) Total Revenue (TR) Total Cost (TC) Average Revenue (A VR) Profit 0 0 0 0 0 0 10 100 20 200 30 280 40 340 50 380 60 400 70 400 80 380 90 340 (a) The cost of operating a well is €60/day and the value of water to each farmer is €0.1/liter.

"Population, Resources, and the Environment Much of the concern over environmental issues stems from the perception that we may reach a limit to the number of people whose needs can be met by the earth’s finite resources. We may or may not reach this point, given the potential for new technological discoveries, but it is clear that continuing on our present path of accelerating environmental degradation would severely compromise the ability of present and future generations to meet their needs. A slowing of population growth rates would help ease the intensification of many environmental problems. However, the rate and timing of fertility declines, and thus the eventual size of world population, will largely depend on the commitment of governments to creating economic and institutional conditions that are conducive to limiting fertility." What is the meaning of this statement?
