1. Optimal choice of capital Eleanor makes sweaters in her home. Starting with just some knitting needles and yarn, she was able to knit 60 sweaters per year. Now some local stores have expressed interest in her designs and offered to buy her sweaters for $10 each. This makes it worthwhile for her to invest in some capital; in particular, she could produce many more sweaters if she invested in one or more looms, as shown in the following table. Assume that Eleanor's sweater business is a perfectly competitive firm. Complete the following table by calculating the marginal physical product (MPP) of each loom and the marginal revenue product (MRP) of each loom. Quantity of Input (Looms) Output (Sweaters per year) MPP of Each Loom (Sweaters) MRP of Each Loom (Dollars) 0 1 2 3 4 5 60 110 150 184 213 238 50 40 34 29 25 If the rental price of a loom is $270 per year, Eleanor should use 500 400 340 290 250 Suppose the demand for sweaters is very elastic, while the demand for cigarettes is very…

QUESTION 18 The following table shows the DVDS production. Study the table and answer the questions? Labor (L) Total Marginal Product Average Product of MRPL product of labor (TPL) W (MPL) labor (APL) 20 20 30 36 4 40 42 42 1. Based on the above table, how much is the marginal product (MPL) of the 3rd labor? 2. Based on the above table, which labor has the largest marginal product?

4. A decision at the margin Raphael is a hard-working college senior. One Saturday, he decides to work nonstop until he has answered 100 practice problems for his math course. He starts work at 8:00 AM and uses a table to keep track of his progress throughout the day. He notices that as he gets tired, it takes him longer to solve each problem. Time Total Problems Answered 8:00 AM 9:00 AM 40 10:00 AM 70 11:00 AM 90 Noon 100 Use the table to answer the following questions. The marginal, or additional, gain from Raphael's first hour of work, from 8:00 AM to 9:00 AM, is problems. The marginal gain from Raphael's third hour of work, from 10:00 AM to 11:00 AM, is problems. Later, the teaching assistant in Raphael's math course gives him some advice. "Based on past experience," the teaching assistant says, "working on 15 problems raises a student's exam score by about the same amount as reading the textbook for 1 hour." For simplicity, assume students always cover the same number of pages…
