This report provides estimates of the value of outputs, inputs, and markets served by elements of the transportation services industries in Washington State. The study is an extension of The Washington State Input-Output Study for 1982 by the inclusion of a detailed examination (by mode of transport) of purchase-sales relationships. Portions of the report address the conceptual and empirical problems in measuring regional interindustry flows in the transport sectors, and particularly the methodological limitations surrounding synthetic I/O models and survey approaches.
A gross flows matrix (62 x 64), direct requirements table (59 x 59), and output multiplier matrix with households endogenous are included. Impact multipliers (value added, earnings, jobs) for the transport sectors are included.
The study provides estimates of the economic importance of the transportation industry in Washington. The model facilitates the evaluation of the impact of autonomous changes in the demand for transportation services upon the rest of the regional economy, and the estimation of the impacts of changes in the rest-of-the-economy upon the demand for transportation services in Washington State.
