To determine
To determine: The GDP as the value added production, as spending on final goods and services and as factor income.
Concept Introduction:
Expert Solution & Answer
Explanation of Solution
a. GDP as the Value added in production.
The value addition can be calculated by the value of input from the value of output, in the given case the value addition can be calculated by summing up the value addition to the pizza company, bread company and the cheese company.
Formula to calculate value addition:
Value addition to bread company is $50
Value addition to cheese company is $35
Value addition to pizza company is $115
Substitute $50 for value addition to bread company, $35 for value addition to cheese company, and $115 for value addition to pizza company.
Therefore, GDP by value addition will be $200.
Conclusion:
Thus, GDP by value addition will be $200.
b. GDP as spending on final goods and services.
For the calculation of spending on final goods and services, only the output of pizza company is to be calculated because the output produced by other two companies will be the input for pizza company. Therefore, GDP as spending on final goods and services will be $200.
Conclusion:
Thus, GDP as spending on final goods and services will be $200.
c. GDP as factor income.
To calculate GDP as factor income, the factor income of all the three companies are needed to be calculated. In the given cases, factor income of all three companies is the sum of the wages and their profits.
Formula to calculate GDP as factor income:
Factor income of bread company is $50
Factor income of cheese company is $35
Factor income of pizza company is $115
Substitute $50 for factor income of bread company, $35 for factor income of cheese company and $115 for factor income of pizza company:
Conclusion:
Thus, GDP as factor income is $200.

Consider an economy that exhibits both population growth (L grows at rate n) and
technological progress (A grows at rate a) described by the production function,
Y = F(K, AL) = Ka (AL)¹-α
Here K is capital and Y is output.

(c) Find expressions for the steady-state capital-output ratio, capital stock per
effective worker, and output per effective worker, as a function of the saving rate
(s), the depreciation rate (8), the population growth rate (n), the rate of
technological progress (a), and the coefficient a. (You may assume the condition

- Wolfgang is a typical producer in a perfectly competitive piano industry (i.e., all other producers of pianos face the same costs as Wolfgang). The following production and cost data apply to the long run as well as the short run. Fixed costs (rent) are unrecoverable in the short run and are equal to $2400 per month. Variable costs consist of raw materials (wire, wood, plastic), which cost $1000 per piano, and the $40 per hour opportunity cost of Wolfgang's time. Wolfgang's production function is given in the table at right. Wolfgang will shut down if the price per piano is less than OA. $3000. B. $4000. O C. $5000. ○ D. None of the above.
