how to find the model of each equation which variables are in a simultaneous equation? which type of variable is an exogenous variable? which of the following is an exogenous variable that is always in the model for a paired equation? how do you find the __________ in every equation what is the inverse equation that shows the relationship between an exogenous variable and an exogenous variable? which variables are exogenous variables what is the model of the parallel equation what variables are exogenous or exogenous if one has a pair of exogenous variables which type of model would be used to identify all the pairs of equations in the same equation? what is the exogenous variable in an equation what is the function of each exogenous variable how to find the corresponding equation how are the exogenous variables identified in a simultaneous equation? which model is not identifiable if the variables are all endogenous which of the exogenous variables is the same as the exogenous variable how to determine which endogenous variable is the same as any other variable how to tell when one equation is exogenous how to identify the equation of the sum of the exogenous variables which is an exogenous variable in an equation?
