Transaction Sequencing and House Price Pressures
利用挪威住房交易数据，研究发现搬家房主临时改变交易顺序（先买后卖或先卖后买）会暂时推高当地房价和卖方流动性，并首次估计出房价对市场紧度的弹性约为0.1。
We use a unique data set of individual housing transaction histories from Norway and a novel shift-share design to show that temporary changes in the transaction sequencing decisions of moving homeowners—whether to buy first and then sell or vice versa—cause temporary local increases in house prices and seller liquidity. Our findings are consistent with a simple theory of how transaction sequencing decisions impact house prices in a frictional housing market. We also provide the first causal estimate of the elasticity of house prices to market tightness, which is around 0.1. Overall, our findings highlight the importance of trading frictions and supply-demand imbalances for housing market dynamics. This paper was accepted by Bo Becker, finance.
