Managerial Economics: Demand Analysis

This assignment focuses on analyzing the demand for Good 1 using a linear-linear regression model. Students estimate the model and analyze various elasticities, including price, cross-price, and income elasticity. They interpret the results to determine if Good 1 is elastic or inelastic, a substitute or complement, and classify it as a normal or inferior good. The assignment also includes forecasting Q1 given specific values for P1, P2, and INCOME.

Given the demand data answer the following questions after estimating your regression model of
demand for Good 1. Quantity demanded of Good 1 is given by Q1 and the price of Good 1 is
given by P1. The price of Good 2 is given by P2. Use a linear-linear functional form (i.e., do not
transform the variables in anyway, such as with natural logarithms). Many economists refer to
this as a “lin-lin” functional form. Evaluate elasticities at the sample means of the data.
1. What is the change in Q1 given a change in P1? -27.08
2. Is it statistically significant at the 95% level? yes
3. What is the mean of Q1? 56.33
4. What is the mean of P1? 3.05
5. What is the price elasticity of demand for Good 1? -1.47
6. Is the demand for Good 1 elastic or inelastic at the sample means of the data? Elastic
7. To increase revenue, the firm selling Good 1 should raise or lower price? lower
8. What is the change in Q1 given a change in P2? 12.24
9. Is it statistically significant at the 95% level? yes
10. What is the mean of P2? 1.24
11. What is the cross price elasticity of demand of Good 1 given a change in the price of
Good 2? 0.27
12. Are Goods 1 and 2 substitutes or complements? Substitutes
13. What is the change in Q1 given a change in INCOME? 0.002
14. Is it statistically significant at the 95% level? Yes
15. What is the mean of INCOME? 32291.76
16. What is the income elasticity of demand for Good 1? 1.15
17. Is Good 1 a normal or inferior good? normal If normal, what type? luxury
18. What is the adjusted R2? 0.788

19. Given P1 = $3.75, P2 = $1.65, and INCOME = $38000 what is the forecasted value of Q1?
58.76
20. Given P2 = $1.65 and INCOME = $38000 what is the revenue-maximizing level of Q1?
79.9 What is the corresponding level of P1 that maximizes revenue? 3.995
