- The small economy of Pizzania produces three goods (bread, cheese, and pizza), each produced by a separate company. The bread and cheese companies produce all the inputs they need to make bread and cheese, respectively. The pizza company uses the bread and cheese from the other companies to make its pizzas. All three companies employ labor to help produce their goods, and the difference between the value of goods sold and the sum of labor and input costs is the firm’s profit. The accompanying table summarizes the activities of the three companies when all the bread and cheese produced are sold to the pizza company as inputs in the production of pizzas.
Bread company Cheese company Pizza company Cost of inputs $0 $0 $50 (bread) 35 (cheese) Wages 15 20 75 Value of output 50 35 200 Question

- Eastland College is concerned about the rising price of textbooks that students must purchase. To better identify the increase in the price of textbooks, the dean asks you, the Economics Department’s star student, to create an index of textbook prices. The average student purchases three English, two math, and four economics textbooks per year. The prices of these books are given in the accompanying table.

The consumer price index, or CPI, measures the cost of living for a typical urban household by multiplying the price for each category of expenditure (housing, food, and so on) times a measure of the importance of that expenditure in the average consumer’s market basket and summing over all categories. However, using data from the consumer price index, we can see that changes in the cost of living for different types of consumers can vary a great deal. Let’s compare the cost of living for a hypothetical retired person and a hypothetical college student. Let’s assume that the market basket of a retired person is allocated in the following way: 10% on housing, 15% on food, 5% on transportation, 60% on medical care, 0% on education, and 10% on recreation. The college student’s market basket is allocated as follows: 5% on housing, 15% on food, 20% on transportation, 0% on medical care, 40% on education, and 20% on recreation. The accompanying table shows the September 2012 CPI for each of the relevant categories.
Calculate the overall CPI for the retired person and for the college student by multiplying the CPI for each of the categories by the relative importance of that category to the individual and then summing each of the categories. The CPI for all items in September 2012 was 231.4. How do your calculations for a CPI for the retired person and the college student compare to the overall CPI?CPI September 2012 Housing 223.9 Food 234.2 Transportation 221.7 Medical care 418.0 Education 134.6 Recreation 115.0 Question
