Document Summary

Ec 140- lecture 3: measuring national income; chapter 20. Gdp is total production in a country. If a production was sold and consumer, gdp would be easy to measure. Outputs of one company are inputs to another. Measuring value of output counts some output more than once. To avoid double counting- measure value added by all firms. Value added is sales revenue- cost of intermediate goods. Value added is definitionally equal to wages paid to workers plus profits paid to owners. Total value added in the economy is a measure of total output. Gdp is the total value of final goods and services produced. Wide range of approaches to measuring gdp: value of final goods and services produced, value added by all firms in the economy, value of expenditure on output. Production, expenditure and income are all equal by definition. Consumption expenditure: goods and services sold to final users. Investment expenditure: goods not for current consumption.

Gross Domestic Product (GDP) only measures the value of marketed goods and services for a country during a given period of time.

Is the GDP measure underestimating or overestimating national production and total income in the economy? Why?

What are the limitations of the GDP in measuring total output and national welfare? What products (services) are excluded from the GDP computation?

Intermediate goods are goods and services that are purchased for resale or for further processing or manufacturing. Final goods are consumer goods, capital goods, and services that are purchased by their final users, rather than for resale or for further processing or manufacturing. Including the value of intermediate goods in the measure of real GDP would amount to multiple counting, and therefore distort the value of GDP. Value added is the market value of a firm’s output less the value of the inputs the firm has bought from others.

Using the table below, calculate the total sales values, value-added, and fill in the missing boxes. The product is assembled for sale is a fancy wool suit.

Stages of Production	Sales Value of Materials or Product	Value Added
	$0
Firm A: Sheep Ranch		$120
Firm B: Wool Processor	$180
Firm C: Suit Manufacturer	$220
Firm D: Clothing Wholesaler		$50
Firm E: Retail Clothier (Market)		$80

The table below shows the price of inputs and the price of outputs at each step in the production process of making a shirt. Assume that each of these steps takes place within the country.

	Cotton farmer	Fabric maker	Sewing and printing
Inputs	$0	$1.10	$3.50
Value of output	$1.10	$3.50	$18.00

a. Using the standard expenditure method, the total contribution of this shirt to GDP is $_____.

b. If we use a value-added method (i.e., summing the value-added by producers at each step of the production process, equal to the price of inputs minus the price of outputs), the contribution of this shirt to GDP is $_____.

c. If we mistakenly added the price of both intermediate and final outputs without adjusting for value-added, we would find that this shirt contributes $_____ to GDP and this overestimates the true contribution by $_____.
