2. [Macroeconomics: The Big Picture – Measuring Production, Income, and the Spending of Nations] Charles has a new small business that makes and sells amigurumi—crocheted stuffed animals. Charles already has crochet tools such as needles and a yarn ball winder, but needs to rent studio and retail space, as well as purchase project-specific supplies. These are his revenues and costs for his first week of operating.
Revenue = $5,000
Costs:
Rental Fee For Studio Space = $800
Rental Fee For Retail Space/Equipment = $1,000
Yarn = $900
Stuffing = $200
Wages = $1,200
a) Calculate the value added by this firm. (Hint: what are the intermediate goods?)
b) Show that value added equals capital income plus the labor income paid by the amigurumi firm. (Hint: what comprises capital income?)
c) Suppose that there is a sudden increased interest in amigurumi. This causes two things. First, the firm’s revenue rises from $5,000 to $6,500. Second, there is an increased demand for yarn. The firm must now pay $1000, instead of $900. Please repeat (a) and (b) with these new values.
Answer:
Revenue = $5,000
Costs:
Rental Fee For Studio Space = $800
Rental Fee For Retail Space/Equipment = $1,000
Yarn = $900
Stuffing = $200
Wages = $1,200
a)
Value added=Revenue of the firm-Cost of intermediate goods=$5000-($900+200)=$3900.
Intermediate goods are Yarn and stuffing.
b)
Capital income= Rental Fee For Studio Space $800+ Rental Fee For Retail Space/Equipment $1,000+Profit $900=$$2700.
Wage Income=$1200.
Capital income+Wage income=$2700+$1200=$3900=Value added.
Profit is calculated as Revenue-Cost of goods sold=$5000-$(800+1000+900+200+1200)=$900.
c)
Revenue is increased to $6500, Yarn=$1000
Value added=Revenue of the firm-Cost of intermediate goods=$6500-($1000+200)=$5300.
Capital income= Rental Fee For Studio Space $800+ Rental Fee For Retail Space/Equipment $1,000+Profit $2300=$$4100.
Wage Income=$1200.
Capital income+Wage income=$4100+$1200=$5300=Value added.
Profit is calculated as Revenue-Cost of goods sold=$6500-$(800+1000+1000+200+1200)=$2300.
