China’s high household savings rate has been continually debated in the past three decades. The wave of existing literatures has provided a considerable innovative theoretical ideas and empirical estimates. In recent years, there has been a trend that Chinese young generations are delaying their marriage and childbirth. This study aims to find out whether the delayed marriage has posted an effect on the savings rate and how the mechanism behind the potential correlation. In this paper, we first exert a standard overlapping generation model (OLG) to match a society in which households start their marriage and childbirth at the age of 40. Next, we construct a modified OLG model to represent another society when generations get married and have a child in their 20s. According to these two forms of model, we calculate and compare the corresponding steady-state values in the economy. In comparison with the benchmark, it predicts that a late marriage and childbirth made no difference on the steady-state values. That is to say in the long run the household savings rate would be in the same level under the economy with or without delayed marriage and childbirth. After algebraically solving the identical steady-state values, this paper considers a compounded economy that agents suddenly decide to have a later marriage and childbirth. Assume agents initially give birth to a baby at the age of 20 than in any given period they abruptly get married and have children at the age of 40. Regarding the economy, it is clear that this decision immediately led to a lack of labor force in the society. The reduced participation of labor force had posed an important effectt on the whole economy. In order to find the unambiguous change of output, capital accumulation, wage rates, interest rates as well as saving rates during the transition, the numerical analysis is processed with Excel. The dissertation has assigned values to the parameters and simulated out time paths of the variables under the compounded economy. It is concluded that the suddenly delayed marriage has a temporary effect and the savings rate will fluctuate during the transition. The household savings rate would back to the pre-shock steady-state level over time.
