Assignment 2: Coase Theorem For our purposes, assume we can define the Coase Theorem as “if property rights are well defined, and there are not significant transaction costs, an efficient allocation of resources will occur, even if externalities exist.” Page 57 in Harris begins a discussion of the Coase Theorem. A description and example applications are shown. Your assignment is to make up your own hypothetical scenario for the application of the Coase Theorem. Describe your scenario (in your own words) and create a distribution of benefits table under different rights. Your results should look something like Table 3.3 (page 59) in Harris. Submit your scenario description and be sure it includes your table. Up-load your paper as pdf or MSWord file. Include your name in the file name. For example “gsewellAssign2.pdf”. Assignment 3 Now that we have studied the common pool issue as illustrated by the fisheries example, lets apply our efforts to another natural resource. Aquifers can behave as common pool resources, even in states like Oklahoma where they are technically private property. As you might guess, Ronald Coase (and I) could attribute this to incompletely defined property rights (i.e. How much is mine). For our example we will use a discrete aquifer used for irrigation/agriculture. Assume that the electricity costs $10 a day to pump a well. We will simplify the agriculture part and just say that a gallon of water produces $0.003 worth of profits from the crops grown. If that seems low that is about what citizens in Ada pay for municipal water. In this example (see assignment spreadsheet) total water output (gal/day) would be analogues to the total catch per season. 1. I have plotted aquifer output (gal/day) for you. Define the zones of constant returns, diminishing returns, absolute diminishing returns. 2. Plot the total cost, water value and profits (per day) vs number of wells 3. Plot the marginal cost per well, marginal revenue per well, and average revenue per well vs number of wells. 4. Based on your findings: a. what # of wells yields the production maximum (total gallons) of the aquifer? b. What is the maximum number of wells that yields profits (open access equilibrium)? c. What number of wells yields maximum profits? d. Based on marginal cost and marginal revenue, what number of wells yield the efficient outcome? 5. What could you do to achieve an efficient outcome? Outline your plan. Assignment 3 Now that we have studied the common pool issue as illustrated by the fisheries example, lets apply our efforts to another natural resource.

1. I have plotted aquifer output (gal/day) for you. Define the zones of constant returns,
diminishing returns, absolute diminishing returns.
The zone of constant returns is the point where the returns do not change as business contracts
or expand (Gupta, Bahri, Cotter, & Canini, 2018). Each extra investment of capital and labor
yields the same returns as before. The cost of the product per unit remains the same whatever
the production scale. The returns increase when the business moves towards the optimum and
the returns decrease when it goes past the optimum. The returns continue to remain the same
after an optimum point is reached, at that output level, the industry is stabilized and they are
said to be constant. The constant return from the graph is 800,000 gallons of water. As the
number of the amount of producing wells is incrementally increased, there is a decrease in the
marginal production process output while the quantities of all other factors of production
remain the same. This is the diminishing returns and it is a point where the number of producing
wells is 150 and the total groundwater produced is 800,000 gallons from the graph. The
absolute diminishing return is the point at which outputs start to decrease (Gupta, Bahri, Cotter,
& Canini, 2018). From the graph, this point is where the number of producing wells is 175
while the total groundwater produced is 800,000 gallons.
2. Plot the total cost, water value and profits (per day) vs the number of wells (excel)
3. Plot the marginal cost per well, marginal revenue per well, and average revenue per
well vs a number of wells. (Excel)
