Endogenizing Consumption In The Input†Output Model: Theory And Application

Since the basic model of input†output analysis does not take into consideration the income effect on consumption expenditure, we constructed a model which endogenizes consumption and breaks down integrated production inducement into Leontief and Keynesian effects in a generalized context and in two solution approaches. Using short†term marginal consumption propensities, we estimated that Keynesian effects make up about 14% of the integrated inducement effects for Japan. The public services sector, which is not influential in the basic model, becomes very influential in consideration of Keynesian effects. Manufacturing and service sector products are the main targets of the expanded consumption. The impact of a change in exogenous final demand can be easily simulated by applying the suggested apparent input coefficient matrix to the integrated inverse matrix.
