One type of systematic error arises because people tend to think of benefits in percentage terms rather than in absolute dollar amounts. As an example, Samir is willing to drive 20 minutes out of his way to save $4 on a grocery item that costs $10 at a local market. But he is unwilling to drive 20 minutes out of his way to save $10 on a laptop that costs $400 at a local store. In percentage terms, how big is the savings on the grocery item? On the laptop? In absolute terms, how big is the savings on the grocery item? On the laptop? If Samir is willing to sacrifice 20 minutes of his time to save $4 in one case, shouldn’t he also be willing to sacrifice 20 minutes of his time to save $10?

3. Consider a world in which production of a good or service consists of a number of definitive tasks, which must all be performed correctly for the product to have positive value. Each task is filled by a single worker i whose skill level qirepresents the probability the worker performs her task correctly. Mathematically, if there are n tasks in the production of a good, and average production per worker with one unit of capital is 1 when all tasks are performed correctly, the production technology can be represented as:
A) Give an example of an industry for which this might be a good model of production. What does this production function imply about the tradeoff between quality and quantity of labor in a given task? In this, how does it differ from a Cobb Douglas production function?
B) Find the marginal product of increasing the skill of the ith worker. Suppose now there were two firms in the same industry that will bid for workers, and can pay them differentially according to…

- 3. Suppose that individuals with a strong enthusiasm for technology are willing to pay $500 now for the latest iPhone, but only $350 if they must wait a year. Normal people are willing to pay $250, and their desire to purchase does not vary with time. Assume for simplicity that there are equal numbers of each customer type (strong enthusiasm and normal), that the MC of the iPhone is $100, ignore the time value of money, and there are only two years. (Hint: With discrete problems consider all the different options and evaluate each of them to determine the optimal strategy. In this case, there are only three prices given and two time periods, so a total of 6 pricing strategies exist but some of them will.) What is the highest profit level that can be achieved if the price for an iPhone is fixed for both years (uniform pricing)? What is the highest profit level that can be achieved if the price for an iPhone can be altered across the two years?arrow_forward1.

They know from the last time they did these chores that it takes Verania 2 hours to vacuum and 1 hour to wash dishes. It takes Josimar 3 hours to vacuum and 2 hours to wash dishes. Josimar says it does not matter which task each of them performs because Verania is faster at both tasks. Josimar’s reasoning a. is wrong. Because Verania has a comparative advantage in washing dishes, she should wash dishes, and Josimar should vacuum. b. is correct. Because Verania is faster at both tasks, there is no benefit in each volunteer specializing in one task or the other. c. is wrong. Because Verania has an absolute advantage in both tasks, she should perform both tasks herself. d. is wrong. Because Josimar has a comparative advantage in washing dishes, he should wash dishes, and Verania should vacuum.arrow_forward(Last Word) The government can overcome the asymmetric information problem regarding pollution abatement by Multiple Choice placing an outright ban on gasoline. placing a carbon tax on any firm that reveals its emissions. none of the above. implementing mandatory vehicle smog checks.arrow_forward

Her objective is to maximize the savings she will have in the bank five years from now. If she goes directly to work, she will earn $22,000 per year for each of the next five years. If she goes to junior college, for each of the next two years she will earn nothing—indeed, she will have to borrow $6,000 each year to cover tuition and books. This loan must be repaid in full three years after graduation. If she graduates from junior college, in each of the subsequent three years, her wages will be $41,000 per year. Joanne’s total living expenses and taxes, excluding tuition and books, equal $15,000 per year. Instructions: Enter your responses as whole numbers. a.
