The aim of this paper is to survey the Miyazawa model, which incorporates the Keynesian-Kaleckian multiplier analysis with the Leontief's model, and to analyze the dynamic and structural aspects of the Miyazawa Model. In section 2, we examine the multiplier analysis from the Keynes-Kalecki-Leontief perspective. In section 3, we present the Miyazawa model with a focus on the income-distributional multiplier. In section 4, we present an inter-industry expansion on the post-Keynesian perspective. Finally, in section 5, we present the concluding remarks that include comments regarding the current economic policy implications of public policy and private investment. One of Miyazawa's main contributions to economics was the creation of the full inter-relational income multiplier from the rather simplified Keynesian structure.Kalecki (1971) and Keynes (1936) considered a capitalist economy as a demand-constrained system, based on the principle of effective demand. According to this principle, the relationships among income, employment and capital stock in a given year was adjusted according to the expected final demand.Trigg (1999) attempted to integrate Marx with Keynes through Miyazawa's multiplier framework as a starting point. In a similar manner, we can also integrated Keynes with Kalecki through Leontief's output multiplier. We then used the input-output model to estimate the economic damage repercussion of voluntary self-restraint on recreation industries following the Great East Japan Earthquake by the use of the 2005 Input-Output table of Japan. The estimate was 2.8105 trillion yen for the decrease in the private consumption demand. Economic repercussion effects summed up to minus 5.6895 trillion yen by means of an endogenous consumption model.In such an economic situation, the structural Keynesian policies play important roles in private consumption and public policy investments when macroeconomic impacts are of interest.JEL Classification: E21, E22
