渇水時の水消費行動のモデル分析

Abstract

This paper presents a households' behavior model in drought time.In drought time, the difficulty of gaining the required amount of water increases and households are forced to reallocate their resources to produce water-dependent in-house services.In this paper, the difficulty induced by drought is expressed in terms of increased time to obtain a unit amount of water.A demand model is proposed to theoretically analyze the demand substitutions between different services as the time to gain water increases in drought time.It is shown that both the preferences for in-house services and the characteristics of households technology to produce in-house services determine the substitution patterns of the services and factor demands for inputs for the in-house services' production.
