2.1 - 2.2

  • circular flow model

    • 2 economic actors: households and businesses

    • 2 markets in economy

      • product market: businesses provide goods and services to households, households provide sales to business

      • factor market: resources are bought and sold; land, labor, capital, and entrepeneurship are sold to businesses from households; businesses provide wages, rent, interest, and profit in return

    • money flow - dollars flowing around being used to purchase goods and services

    • real flow - economy

    • money flow helps real flow move more freely

    • for a free market economy

    • us has the government involved - gov buys goods and services and factors of production. provides public goods to all and charges taxes to pay for them

    • leakages:

      • when money exits the circular flow

      • imports, savings (not being spent), taxes to gov (pulls money out)

    • injections:

      • when money enters the circular flow

      • exports, loans, government spending

    • spending in product = income in factor

  • gross domestic product

    • total value of all goods and services produced within a country in a calendar year (only final goods, not intermediate goods)

    • value added approach:

      • adds contributions a country’s firm makes to the final goods

      • sales from domestic minus payments to foreign firms

    • income approach:

      • rent, wages, interest, and profit added together

      • sum of all payments for factors of production

      • disposable income: personal income minus taxes

    • output expenditure model:

      • c + i + g + nx (exports minus imports)

      • c | consumption — all goods and services purchased by consumers

      • i | gross investment — primarily business purchases of physical capital and changes in inventories. unexpected increase = probably a recession. houses r investment. net investment = gross investment minus depreciation

      • g | government purchases — expenditures where the gov receives a good or service from their spending (i.e. no social security etc)

      • n | net exports — x minus m, exports minus imports

    • what isnt counted?

      • used goods

      • intermediate goods (no double counting)

      • financial transactions (e.g. stocks and bonds, grants and loans)

      • transfer payments (e.g. food stamps)

    • limitations

      • per capita gdp = gdp / population

      • higher per capita gdp = higher standard of living

      • underground economy: illegal transactions are not counted, cash, etc

      • non market activities / household production

      • bads counted as goods - pollution of natural resources and clean up will count as positive

      • income distribution - not reflected in gdp


2.3
