By embedding a conventional static Leontief input-output model within an activity analysis framework. an activity-commodity system can be substantially said to be an extended input-output model. An activity-commodity framework can be expressed as two or more subsystems, and in this case household sectors can be treated as demographic activities and commodities. Assuming that there are two subsystems. the interaction between activities and commodities can be analyzed through the partitioned matrix. Where household sectors are described within an extended input-output model. the economic effects, which are very different from those of household-endogenous input-output model, can be given on the basis of the issues discussed above, the research objectives of this paper are :
1) To examine the role of the household sector in a traditional input-output model and an extended input-output model to compare their different economic effects; and,
2) To explain the interaction and feedback effects between the two subsystems. By combining two models which utilize the advantages of an input-output model and linear programming, a conceptual framework can be developed to solve the problem of resource allocation. The major research findings of this study can be summarized as follows.
1) There are two different ways to deal with the household sector in an input-output model: the first is open and the second is closed with respect to households. The open model assumes that a household is defined as outside of the system because the household is considered to be one of the unstable economic sectors. If a household is treated exogenously, the direct and indirect output requirements can be obtained only through the changes in final demand. Suppose thai a household is a kind of endogenous industry. Then, the direct, indirect, and induced output requirements are calculated, which takes into account both the impact of demand on supply and that of supply on demand. In spite of the merits which obtain the induced output requirements from this approach, there is a problem with this model. Because households have varied consumption patterns,it is unrealistic to treat households as a single row and column.
In such a treatment. if a household-endogenous model is used, the consumption
coefficients must be revised often to maintain the accuracy of the Leontief inverse.
2) Activity analysis is defined as a method of analyzing any economic transformation in terms of elementary units called activities. It is a comparatively simple matter to compare an input-output model with an activity-commodity framework. Instead of industrial sectors, we refer to industrial activities and industrial commodities. We also substitute gross output and final demand for activity levels and constraints, respectively.
Then the activity-commodity framework can be written as equations (3-3) and (3-7).
〔coefficients matrix〕〔activity levels〕 = 〔constraints〕 (3-3)
AX = B (3-7)
If there is only one activity for each produced commodity and no limitation on primary factors, the Leontief equilibrium system (3-13) may be understood as a special case of the system (3-7), because the Leontief matrix (I-A) can be expressed as a submatrix of the coefficients matrix, A, in activity analysis.
3) An input-output model can handle successfully the problems of capacity limitation of a specific industry and the allocation of fixed resources. Suppose that we wish to employ the entire labor force. Then the total amount of labor available, N, must be added to the input-output equilibrium system. In addition to the limited labor supply, suppose further that the output capacity of industry i is restricted to ?? units, only on the condition that we also wish to fully utilize the production capacity of industry i. In addition to these cases. the input-output method can obtain the set of final goods and services we ought to produce to maintain the full utilization of fixed resources, a case where n producing sectors is equal to m fixed resources. But we can also find many
feasible solutions instead of a unique one: cases where an input-output system involves an inequality and n is greater than m. In these cases, we find examples which require the optimization technique of linear programming to solve the problem of choosing among feasible solutions.
4) The interaction between two or more subsystems is effectively described by
partitioning the matrix within a generalized input-output framework. By representing a static input-output model by two subsystems. we derive an equation (4-2). which is identical with an equation (3-7) a typical activity analysis framework. Moreover. we specify households in an economic-demographic activity analysis system: this system then has four different submatrices of the coefficients matrix, as shown in figure (Ⅳ-1). The first quadrant, which is a demographic-economic interaction submatrix, contains the household consumption coefficients. Quadrant II is the Leontief (I-A) submatrix, whereas
quadrant Ⅲ includes labor demand coefficients expressing the number of workers
'consumed' per unit of gross output for each industrial activity. The fourth quadrant, a demographic interaction submatrix, sets forth the nature of household formation and generation of its labor supply.
In conclusion, this paper focuses on the role of the household sector within the conceptual framework of activity analysis. However, further work must be done on the empirical side. Furthermore, an additional research is required, because I am convinced that the fundamental model will become more useful as a tool of economic analysis through modifications and extensions.
