24
Q

what are three different ways to estimate GDP?

A
  • spending: households, firms, gov and residents of other countries on home economies products
  • Production: total produced by the industries value added by each industry (COGS subtracted from value of output)
  • income: sum of all the incomes received as wages, profits and the incomes of the self employed

national accounts can be taken at any stage, if measurement accurate should be the same whichever stage (any spending is income for whoever sold it, which must have also been produced)

25
Q

what is the circular flow of the economy?

A

money flows from the spender to the producer, from the producer to their employees and then is spent again on further output, continuing the cycle, using monetary value to contrast GDP

26
Q

what is the interaction between firms and households in terms of economic flow?

A

households spend on firms
households provide labour
firms provide value to households, income as wages
firms provide goods and services to households

27

A

households pay taxes to gov

gov then use tax for schools to households

28
Q

government can be considered a product like a firm, but under what assumptions ?

A
  • that the value added is the same as its cost, this is because they are not sold in the market
  • that taxes paid by each household may not correspond with the goods and services they use

house pays £15 that is £15 income to gove which is £15 worth to public sector (value)

29
Q

recession is defined as negative output growth, but if spending, income and production are all the same what does this mean?
