The reasonbehind economic downturn causing problems for Chinese companies that borrowed heavily.
Expert Solution & Answer

Explanation of Solution
The reason for which economic downturn will cause problem for Chinese companies that borrowed heavily are as follows:
- In 2016, a reputed journal stated that number of big investors have invested in the future performance of China. If China economy crashes, then there will a major financial crisis in the world.
- Chinese economy had grown for almost 25 years. So, many economists believed that the boom period in China has ended and economic crisis was looming.
- The weak Chinese economy will lead to devastation as many investors have borrowed heavily during boom time.
- The downturn will lead to political instability in the country which will certainly affect the economical condition.
- It was also believed that the economical stats presented by Chinese government were officially manipulated which meant that the downturn has already begun.

Problem 3
You are given the following demand for European luxury automobiles:
Q=1,000 P-0.5.2/1.6
where P-Price of European luxury cars
PA = Price of American luxury cars
P, Price of Japanese luxury cars
I= Annual income of car buyers
Assume that each of the coefficients is statistically significant (i.e., that they passed the t-test).
On the basis of the information given, answer the following questions
1. Comment on the degree of substitutability between European and American luxury cars and
between European and Japanese luxury cars. Explain some possible reasons for the results in
the equation.
2. Comment on the coefficient for the income variable. Is this result what you would expect?
Explain.
3. Comment on the coefficient of the European car price variable. Is that what you would expect?
Explain.
Problem 2:
A manufacturer of computer workstations gathered average monthly sales figures from its 56 branch
offices and dealerships across the country and estimated the following demand for its product:
Q=+15,000-2.80P+150A+0.3P+0.35Pm+0.2Pc
(5,234) (1.29) (175) (0.12) (0.17) (0.13)
R²=0.68 SER 786 F=21.25
The variables and their assumed values are
P = Price of basic model = 7,000
Q==Quantity
A = Advertising expenditures (in thousands) = 52
P = Average price of a personal computer = 4,000
P.
Average price of a minicomputer = 15,000
Pe Average price of a leading competitor's workstation = 8,000
1. Compute the elasticities for each variable. On this basis, discuss the relative impact that each
variable has on the demand. What implications do these results have for the firm's marketing
and pricing policies?
2. Conduct a t-test for the statistical significance of each variable. In each case, state whether
a one-tail or two-tail test is required. What difference, if any, does it make to…
