A MULTIREGIONAL ECONOMETRIC MODEL OF OHIO*

Abstract

This was produced fro m a co p y o f a docum ent sent to us for microfilming.While the m ost advanced technological m eans to photograph and reproduce this docum ent have been used, th e q u ality is heavily dependent upon the quality o f the material subm itted.The follow ing ex p lanation o f techniques is provided to help you understand markings or n o tatio n s which m ay appear on this reproduction.1.The sign or " ta rg e t" fo r pages apparently lacking from the docum ent p h o tographed is "M issing Page(s)".If it was possible to obtain the missing page(s) or section, th ey are spliced into the film along with adjacent pages.This m ay have necessitated cutting through an image and duplicating adjacent pages to assure you o f com plete continuity.2. When an image on th e film is obliterated with a round black mark it is an indication th a t th e film inspector noticed either blurred copy because of m ovem ent during ex p o su re, or duplicate copy.Unless we m eant to delete copyrighted m aterials th a t should n o t have been filmed, you will find a good image of th e page in th e adjacent frame.If copyrighted materials were deleted you will find a targ et n o te listing the pages in the adjacent fram e.3. When a m ap, draw ing or chart, etc., is part of the material being photo graphed th e photo g rap h er has followed a definite m ethod in "sectioning" th e m aterial.It is cu sto m ary to begin filming at the upper left hand corner of a large sheet and to c o n tin u e from left to right in equal sections with small overlaps.If necessary, sectioning is continued again-beginning below the first row and co n tin u in g on until com plete.
