This study considers a dynamic competitive general equilibrium when time preferences in life-cycle utility are endogenous. We examine how an individual perceives future utilities in a dynastic competitive economy and explore the characteristics of a competitive equilibrium. This paper will discuss the endogenous time preference issue from two different aspects. In the first model, we postulate that each household's time preferences are not only influenced by the parent's consumption and savings behavior in a dynastic intergenerational environment, but also affected by external consumption habits in young cohort households in an intra-generational environment. In the second model, we postulate that in old age, altruistic parents transfer a part of their income to their children, and allocate time for spending with them in order to make them patient and future oriented thus improving their lifetime utility and welfare. In this paper we demonstrate the existence of multiple steady states. The multiplicity of steady states suggests that income inequality arises among households in the dynastic economy.
