In Japan, most goods and services are exchanged through a market system. In the market economy, firms produce and sell goods in order to maximize their profits, consumers buy goods and services to maximize their utility. It is only for private goods and services that resource allocation is efficiently achieved by an invisible hand in a competitive market. But public goods-national defense, diplomacy, education, national enviromental service and so on-are not traded in a competitive market system. Social capital (SC) is defined as the basic source that supplies public goods and services. In this paper, we attempt to analyze in the static and dynamic fields efficient resource allocation. In the static analysis, we first assume that only the SC is used in the production sector, so production function is formed of some factors such as private input, SC service, total SC service, and SC stock. The efficient allocation of resources is obtained through the way that SC service is used until the marginal product of SC service is equal to social marginal cost (SMC). Therefore the rent of SC service must be equal to SMC. The second assumption is that consumers also demand SC service. Then the efficient resource allocation is achieved when the new SMC is adjusted and equal to the production sector's SMC plus consumers' marginal rate of substitution of private goods for SC service. In the dynamic analysis of resource allocation, the same assumptions as for the static analysis are required for every period. It goes without saying that this analysis has some crucial assumptions that utility and SMC are able to be measured and that the operating cost of the rent system is not involved. The next time, I will try to report the optimum growth path.
