Endogenous Land Supply Policy, Economic Fluctuations and Social Welfare Analysis in China

Motivated by the observation that land supplied by the Chinese government is highly counter-cyclical with GDP fluctuations, this paper constructs a DSGE model to study the relationship between China’s land supply policy and economic fluctuations, and further evaluate the welfare effects. By way of counterfactual exercises, this paper finds that endogenous land supply policy has “direct effect (production input channel)” and “indirect effect (intermediate goods channel)” on GDP fluctuations, and both tend to dampen economic fluctuations in China’s macroeconomy. Specifically, GDP fluctuations increase by 63.35% without the “indirect effect”, increase by 66.75% without the “direct effect”, and increase by 66.79% without both effects. In addition, endogenous land supply policy can increase social welfare by about 1.38%. Verifying by the stylized facts in China, this paper argues that endogenous land supply is an efficient macro-control policy to smooth the economy and increase social welfare.
