Consider a market with the following supply and demand. (It may help to draw a graph for these questions.)

If there is an external cost of $3, what is the efficient quantity? 500 (already answer)
If there is an external benefit of $3, what is the efficient quantity? 700 (already answer)
For the remaining questions assume that there is a $3 external COST.
If the government wants to get the efficient quantity with a per/unit tax, how much should the tax be? 3 (already answer)
Now imagine that they use tradable allowances. If they cap the quantity at 400 what would the value of these allowance be in the market? (Assume the market is
What will they be worth if the quantity is capped at 500?
What if it is capped at 700?

- 1. Consider a pure exchange economy with two goods and two consumers. Let F denote food and C denote clothing. Lacy has the utility function U(F, C) = F 1/3 C 2/3 . Roy has the utility function V (F, C) = F 2/3 C 1/3 . Each consumer has an initial endowment consisting of 9 units of F and 9 units of C. Normalize the price of F to one. Let P denote the price of C. (a) Is the initial endowment a Pareto efcient allocation of F and C between the two con sumers? Explain briefy. (b) What is each consumer’s demand for F and C as a function of P? [Hint: the wealth of each consumer is 9 + 9P.] (c) What is the price of C in a competitive equilibrium? (d) What is the allocation of F and C between the two consumers in a competitive equilibrium?arrow_forwardIndustry is evaluating two different manufacturing systems (Alpha and Beta): Possible Outcome Probability Rate of Return Alpha System Rate of Return Beta System Optimistic .35 .40 .15 Most likely .45 .25 .30 Pessimistic .20 (.10) (.20) Which manufacturing system provides the lowest expected return? why? Alpha System Beta System Not enough informationarrow_forwardThe spread is a function of a variety of factors. You can think of the spread as a function of these factors. For example: Spread = f(Order Costs, Inventory Costs, Competition, Volume, Currency Risk) All else equal, if the volume increases then the spread will most likely increasearrow_forward
- A consumer's utility only depends on the consumption of goods A and B according to the following Cobb - Douglas utility function: U(A, B) = A3/5 B 2/5. The price of goods A and B are $10 and $10, respectively. The consumer has a budget of $1500 that he can use to consume the two goods. a) Calculate the optimal bundle and maximized utility for the consumer. b) A new tax of $5 is imposed on the price of good B. Compute the new optimal bundle of good A and B for the same consumer. What is the utility loss due to the tax? c) Show that the consumer would prefer a lump sum income tax that raises the same revenue of $200 as the tax on good B.arrow_forwardConsider the following duopoly model and determine profit - maximizing output and price for q_1+ q 2 TC_1 = 10 q_(1) TC_2 = 10 q_2 each firm.
