In a microeconomic model, how would you differentiate between an 'exogenous' variable and an 'endogenous' variable? Endogenous variables are those determined within the model, while exogenous variables are given from outside the model. Exogenous variables are those which economists do not study, while endogenous variables are heavily studied. Exogenous variables are variables that economists cannot measure, while endogenous variables are measurable. Exogenous variables cannot influence endogenous variables in any economic model. More than one of the above.
