Circular-Flow diagram, revisited: underlying principle
the inflow of money into each market or sector = outflow of money coming from that market or sector
simple world has households and firms
Households:
Govt borrowing
total amt of funds borrowed by federal, state and local govts in the financial markets (along with tax revenues, $ borrowed is used to buy goods/services)
Govt purchases of goods and services
total expenditures on goods/services by federal, state and local govts (ie military spending on ammunition, local public schools expenditures)
Exports
goods/services sold to other countries
imports
goods/services bought from other countries
inventories
stocks of goods/raw materials held to facilitate business operations
Investment spending
spending on productive physical capital (ie machinery and construction of buildings, and on changes to inventories (an increase in inventory produced changes the ability of a firm to make future sales.) Conversely, a drawing down of inventories is counted as a fall in investment spending because it leads to lower future sales. Construction of homes is included because a new house produces a future stream of output – housing services for it’s occcupants.
Another way to define GDP
consumer spending + investment spending + govt purchases + value of exports – value of imports = measure of overall market value of goods/services the economy produces.
Final goods/services
those sold to the final or end user
Intermediate goods/services
bought from one firm by another firm that are inputs for production of final goods/services
YEt another way to define GDP
total value of all final goods/services produced in the economy during a given year
Aggregate spending
the sum of consumer and investment spending, govt purchases of goods/services, and – imports = total spending on domestically produced final goods/services in the economy
