MEASURING NATIONAL OUTPUT AND NATIONAL INCOME MEASURING NATIONAL OUTPUT AND NATIONAL INCOME National income and product accounts = Data collected and published by the government describing the various components of national income and output in the economy.

= The total market value of all final goods and services produced within a given period by factors of production located within a country. [1]? Principles of?? = Goods and services produced for final use. = Goods that are produced by one firm for use in further processing by another firm.

Wheels & Tires = $4,000. Suspension & Steering & Transmission & Brake & Body = $6,000 Interior = $5,000 Glass = $2,000 Assembly and Engine = $7,000 Retail Sale = $30,000

? = The difference between the value of goods as they leave a stage of production and the cost of the goods as they entered that stage. Value of Sales Value added Parts $17,000 $ Assembly and Engine $24,000 $ Retail Sale $30,000 $ In calculating GDP, we can either We do not use the value of total sales in an economy to measure how much output has been produced.

[2] Exclusion of used goods & Paper transactions Principle GDP is concerned only with?. House Stocks, bonds AFL

[3] Exclusion of Output Produced Abroad by Domestically Owned Factors of Production GDP is the value of output produced by factors of production located?. The output produced by US citizen abroad? counted in US GDP because the output is not produced within the US. Profits earned abroad by US companies? counted in US GDP. The output produced by foreigners working in the US? counted in US GDP because the output is produced within the US. Profits earned in the US by foreign-owned companies? counted in US GDP.

= The total market value of all final goods and services produced within a given period by factors of production owned by a country s citizens, regardless of where the output is produced. The output produced by US citizen abroad? counted in US GNP. Profits earned abroad by US companies? counted in US GNP. The output produced by foreigners working in the US? counted in US GNP. Profits earned in the US by foreign-owned companies? counted in US GNP.

For most countries, the difference between GDP and GNP is?. 2004: U.S. GNP = $11,788 billion, U.S. GDP = $11,734 billion. 2007: U.S. GNP = $13,937 billion, U.S. GDP = $13,841 billion.

CALCULATING GDP = A method of computing GDP that measures the amount spent on all final goods during a given period. = A method of computing GDP that measures the income wages, rents, interest, and profits received by all factors of production in producing final goods.

THE EXPENDITURE APPROACH Expenditure Categories [1] The? part of GDP. There are three main categories of consumer expenditures: (1)? = Goods that last a relatively long time. (2)? = Goods that are used up fairly quickly. (3)? = The things we buy that do not involve the production of physical things.

Expenditure Categories [2] THE EXPENDITURE APPROACH (1)? = Expenditures by firms for machines, tools, plants. (2)? = Expenditures by households and firms on new houses and apartment buildings. (3)? = The amount by which firm s inventories change during a period. Inventories are the goods that firms produce now but intend to sell later.

GDP is not the market value of total? during a period it is the market value of total?.

THE INCOME APPROACH? = The total income earned by the factors of production owned by a country s citizens.? = Includes wages, salaries, and various supplements employer contributions to social insurance and pension funds, for example paid to households by firms and by the government. Indirect taxes minus subsidies = Taxes such as sales taxes, customs duties, and license fees, less subsidies that the government pays for which it receives no goods or services in return.

The procedure that the BEA used prior to 96 was to pick a base year and to use the prices in that base year as weights to calculate real GDP. This is a fixed-weight procedure because the weights used, which are the prices, are the same for all years the prices that prevailed in the base year. New Procedure: Calculating Real GDP Growth [1] Split the difference. [2] Change of base year.

LIMITATIONS OF THE GDP CONCEPT GDP AND SOCIAL WELFARE Society is better off when crime decreases; however, a decrease in crime is not reflected in GDP. List of countries by murder rate United States cities by crime rate Highest Prison Population Rates An increase in leisure is an increase in social welfare, but not counted in GDP. Countries with highest work hours Nonmarket and household activities are not counted in GDP even though they amount to real production.

LIMITATIONS OF THE GDP CONCEPT GDP seldom reflects losses or social ills. GDP also has nothing to say about the distribution of output among individuals in a society. List of countries by income equality Neutrality about the kinds of goods an economy produces.? = The part of the economy in which transactions take place and in which income is generated that is unreported and therefore not counted in GDP.

HDI HDI Measure of Well-Being, Standard of Living Despite these limitations, GDP is a highly useful measure of economic activity and well-being. GROSS NATIONAL INCOME PER CAPITA Gross national income (GNI) = GNP converted into dollars using an average of currency exchange rates over several years adjusted for rates of inflation. Link
