Estimating the economic impact of the 1973 Navy base closing: Models,tests, and an ex post evaluation of the forecasting performance

In 1973 the Defense Department made plans to close many Navy bases in the United States. Hardest hit was Rhode Island which would suffer a loss of 45.61% of the total cutback of 42,812 jobs. This paper describes two models which were built to forecast the severity of the economic impact in Rhode Island: one used the reduced form equation approach, and the other the simultaneous equations system approach. Tests on multicollinearity, specification, and serial correlation were conducted. An ex post evaluation of these two models' performance in forecasting then concludes the paper.
