Question
Chapter 19, Problem 1.1P
To determine
The expected years that the per capita income of the Democratic Republic of Congo will take to surpass the per capita income of the United States of America.
Concept Introduction:
The per capita income index is an indicator of how much an individual earns in comparison to his peers in an economy during a specific period of time. This indicator helps to understand the standard of living of individuals in different countries by comparing their average per capita income with one another.
Expert Solution & Answer
Explanation of Solution
Currently the per capita income of United States is 160 times greater than the per capita income of Congo. The per capita income growth of United States is 3% per annum in comparison to 6% per annum per capita growth of Congo. Thus, we can understand that Congo’s per capita income growth is 3% faster per annum than the United States.
To calculate the number of years that Congo requires for surpassing the per capita growth of United States:
Where,
g = growth rate
t = number of years required
n = per capita income
Hence, in 171.70 years, the Democratic Republic of Congo’s per capita income will surpass the per capita income of the United States of America, if both the countries continue to grow at the current growth rate annually.

"Whether the regulator sells or gives away tradeable emission
permits free of charge, the quantities of emissions produced by
firms are the same."
Assume that there are n identical profit-maximising firms where
profit for each firm is given by π(e) with л'(e) > 0; π"(e) <
0 and e denotes emissions. Individual emissions summed over
all firms gives E which generates environmental damages
D(E). Show that the regulator achieves the optimal level of total
pollution through a tradeable emission permit scheme, where
the permits are distributed according to the following cases:
Case (i) the firm purchases all permits;
Case (ii) the firm receives all permits free; and

- Suppose there are two firms 1 and 2, whose abatement costs are given by c₁ (e₁) and C2 (е2), where e denotes emissions and subscripts denote the firm. We assume that c{(e) 0 for i = 1,2 and for any level of emission e we have c₁'(e) # c₂' (e). Furthermore, assume the two firms make different contributions towards pollution concentration in a nearby river captured by the transfer coefficients ε₁ and 2 such that for any level of emission e we have C₂'(e) # The regulator does not know the resulting C₁'(e) Τι environmental damages. Using an analytical approach explain carefully how the regulator may limit the concentration of pollution using (i) a Pigouvian tax scheme and (ii) uniform emissions standards. Discuss the cost-effectiveness of both approaches to control pollution.arrow_forwardBill’s father read that each year a car’s value declines by 10%. He also read that a new car’s value declines by 12% as it is driven off the dealer’s lot. Maintenance costs and the costs of “car problems” are only $200 per year during the 2-year warranty period. Then they jump to $750 per year, with an annual increase of $500 per year.Bill’s dad wants to keep his annual cost of car ownership low.

The corporation is a profitable one that has a 22% combined incremental tax rate. At the end of 5 years the mining company changed its method of operation and sold the production machinery for $40,000.
