Subpart (a):
The Investment and the loanable fund market of the economy.
Subpart (a):
Explanation of Solution
Investment is an asset or an item purchased today in the hope that it will generate income in the future. In that sense, the spending of capital on the purchase of new physical capitals refers to the equipment and the buildings and so forth.
When there is no possibility of loanable fund market between the students and each have to invest their own amounts, then each of the students will have the following returns after one year:
Thus, Harry will have $1,050 after one year. Similarly, the returns of Ron and Hermione can be calculated as follows:
Thus, Ron will have $1,080 after one year.
Thus, Hermione will have $1,200 after one year.
Concept introduction:
Investment: It is an asset or an item purchased today in the hope that it will generate income in the future.
Subpart (b):
The Investment and the loanable fund market of the economy.
Subpart (b):
Explanation of Solution
When there is a loanable fund market between the students at the rate of interest 'r', each student will compare the rate of their return with the rate of interest in the loanable fund market for loanable funds, which is 'r'. When the rate of returns is higher than the rate of interest, the student would borrow and if it is lower than the interest rate, then the student will lend.

Investment: It is an asset or an item purchased today in the hope that it will generate income in the future.
Subpart (c):
The Investment and the loanable fund market of the economy.
Subpart (c):
Explanation of Solution
When the rate of interest is 7 percent, Harry would want to lend the money with him because when he compares the
When the rate of interest increases to 10 percent, both Harry and Ron would turn out to be lenders because their rate of return is lower than the rate of interest but Hermione would still be the borrower, since the rate of return is higher than the rate of interest. Here, the quantity of loanable funds demanded is $1,000 and quantity of loanable funds supplied is $2,000.
Concept introduction:
Investment: It is an asset or an item purchased today in the hope that it will generate income in the future.
Subpart (d):
The Investment and the loanable fund market of the economy.
Subpart (d):
Explanation of Solution
The loanable fund market will be in equilibrium when the quantity of loanable funds demanded and supplied in the market becomes equal. At 8 percent rate of interest, Harry would like to lend and Hermione would like to borrow. Ron would use his own savings to invest because the rate of interest and rate of return to him is equal and he would not like to lend or borrow. Thus, the quantity of loanable fund supplied will become $1,000 by Harry and that which was demanded will also become $1,000 by Hermione. This would make the loanable fund

Subpart (e):
The Investment and the loanable fund market of the economy.
Subpart (e):
Explanation of Solution
When the rate of interest in the economy is 8 percent, Ron will use his own capital stock and Harry would lend the amount with him. Thus, both of them will earn the same rate of return which is 8 percent. This can be calculated as follows:
Thus, both of them would earn $1,080. So, the lender Harry would earn $30 higher than without lending a return to him. In the case of Hermione, he will borrow $1,000 from Harry and would invest but he has to repay the $1,000 and its 8 percent interest to Ron. Thus, the returns to Hermione can be calculated as follows:
Thus, Hermione will have a return of $1,320 which is $120 higher than no loanable fund market. Thus, since the borrower and lender are better off in the economy, no one is worse off.

- Just Part D please, this is for environmental economicsarrow_forward3. Consider a single firm that manufactures chemicals and generates pollution through its emissions E. Researchers have estimated the MDF and MAC curves for the emissions to be the following: MDF = 4E and MAC = 125 – E Policymakers have decided to implement an emissions tax to control pollution. They are aware that a constant per-unit tax of $100 is an efficient policy. Yet they are also aware that this policy is not politically feasible because of the large tax burden it places on the firm. As a result, policymakers propose a two- part tax: a per unit tax of $75 for the first 15 units of emissions an increase in the per unit tax to $100 for all further units of emissions With an emissions tax, what is the general condition that determines how much pollution the regulated party will emit? What is the efficient level of emissions given the above MDF and MAC curves? What are the firm's total tax payments under the constant $100 per-unit tax? What is the firm's total cost of compliance…arrow_forward2. Answer the following questions as they relate to a fishery: Why is the maximum sustainable yield not necessarily the optimal sustainable yield? Does the same intuition apply to Nathaniel's decision of when to cut his trees? What condition will hold at the equilibrium level of fishing in an open-access fishery? Use a graph to explain your answer, and show the level of fishing effort. Would this same condition hold if there was only one boat in the fishery? If not, what condition will hold, and why is it different? Use the same graph to show the single boat's level of effort. Suppose you are given authority to solve the open-access problem in the fishery. What is the key problem that you must address with your policy?arrow_forward
