Lecture 1

GDP

 Total expenditure on domestically-produced final goods and services

 Total income earned by domestic households spent on final goods and

services

 Expenditure = Income

 Value of the final good OR sum of value added at all stages of

production

 Value of the final goods already includes the value of intermediate

goods (DO NOT DOUBLE COUNT)

 Y = C + I + G + NX (Value of total output = Aggregate expenditure)

Households + Firms

 Households do labour

 Firms pay households income

 Households use income as expenditures

 Firms give households goods and services for these expenditures

 Expenditure = Income

Value Added

 Must add values based on price, not on total amount of goods

(aggregate value of goods)

 Must add values of increase in production (DO NOT DOUBLE COUNT)

Document Summary

Total expenditure on domestically-produced final goods and services. Total income earned by domestic households spent on final goods and services. Value of the final good or sum of value added at all stages of production. Value of the final goods already includes the value of intermediate goods (do not double count) Y = c + i + g + nx (value of total output = aggregate expenditure) Firms give households goods and services for these expenditures. Must add values based on price, not on total amount of goods (aggregate value of goods) Must add values of increase in production (do not double count) Sale of used/transferred/inventoried goods reflects transfer of an asset not addition to gdp. The value of all goods and services bought by households. These include: durable goods (car), nondurable goods (food), services (air travel) Spending on capital, a physical asset used in future production.

What is the market for factors of production?

What is the market for factors of production?
1. The market for factors of production is where households and firms interact to trade factors of production for factor payments. For example this is where people provide firms with labor and firms pay them with wages.
What is the money market?
1. The money market is where households, firms, and the government may save and/or invest their money to earn interests. Money market includes banks, stock market, bonds market, and other financial institutions where economic actors can buy and sell financial assets to earn interests and/or dividends.
Who are the three economic actors in the circular flow model?
1. In a circular flow model, the three main economic actors are the households, firms, and the government. Households include the typical individual consumers. Firms include businesses and similar producers in the economy. Finally, the government refers to the whole government system from federal to local level.
How is the national income of an economy determined?
1. The national income of an economy is determined by measuring the total value of the output produced in an economy or the total income earned by the actors in the economy. In a circular flow model, we can see that the value of total output produced should equal the total value of income generated and earned in the economy. This is because every dollar spent by someone in the economy is received by another person in the economy as income.
What is GDP?
1. The gross domestic product or GDP represents the sum total of the value of the final goods and services produced within the economy for a given year. It is the most commonly used measure of its economy’s productivity and income.

An improvement in technology causes the production possibilities frontier (PPF) to

	shift to the right.
	pivot upward.
	shift to the left.
	pivot downward.

Which of the following is not shown by the circular flow model?

	The flow of resources in one direction and money in the other
	The equality of aggregate spending and aggregate income
	The interaction of households, firms, and the government
	The total amount of goods and services the economy can produce

(8)

Gross domestic product (GDP) is defined as

	the market value of all final goods and services produced in an economy in a given period of time.
	the market value of all consumption goods and services produced in an economy in a given period of time.
	the market value of all investment goods and services produced in an economy in a given period of time.
	the real value of all investment goods and services produced in an economy in a given period of time.

(9)

Real GDP

	includes all domestic and foreign transactions.
	includes the dollar value of domestic transactions only.
	tries to isolate the effect of changing output, holding prices constant.
	measures GDP in terms of prices of goods and services produced.

(10)

When economists talk about economic growth, they are usually referring to

	the percentage change in nominal GDP.
	the percentage change in real GDP.
	the percentage change in nominal investment.
	the percentage change in real investment.
