ABSTRACT
This chapter examines the question of how sensitive the Ecesis system is to the particular type of demographic model used. An alternative version of the model is created when all the gammas are set to zero. Because the Ecesis economic models expect some age and sex detail, some extensions to the Bureau of Economic Analysis's (BEA) procedure are made in BEA demographic model in order to make comparisons to the other demographic models. Age and sex specific births and deaths are set to the control solution values and treated as exogenous. The control solution, however, is certainly a function of the starting point and that starting point was derived mechanically rather than by considering the particulars of each region. For example, in 1995, the control solution shows increased employment of 85.19 thousand persons, increased real income of $764.3 million and an unemployment rate that is.064 points lower than in the gammao solution.
