taxes

economic models are most often composed of _______ and _______
diagrams, equations

disposable income
people are considered to be unemployed if they:
do not have a job but have looked for work in the past four weeks
what is true about economic models?
economists use different models to address different economic phenomena
3 important characteristics of macroeconomic models:
endo/exogenous variables, simplifying assumptions, implicit/explicit consistency with microeconomic foundations
expenditure on the economy's output of goods and services
exactly equal to the total income of everyone in the economy
the core inflation rate:
excludes food and energy prices
in an economic model, ____ affect ______ variables
exogenous; endogenous
macroeconomic models are used to explain how _____ variables influence ______ variables.
exogenous; endogenous

expected to be between zero and one
