Partly Artificial Data on the U.S. Economy

These are partly contrived data from Kmenta (1986), constructed to illustrate estimation of a simultaneous-equation econometric model. The data are an annual time-series for the U.S. economy from 1922 to 1941. The values of the exogenous variables D, and F, and A are real, while those of the endogenous variables Q and P are simulated according to the linear simultaneous equation model fit in the examples.
