This paper examines households’ extrapolative behaviors and developers’ strategic responses in China's land and housing markets. Our stylized model predicts that when households extrapolate in the housing market, developers with nearby land holdings strategically bid higher, anticipating rising housing prices to boost the value of their existing stock. Using the exogenous timing of land auctions, we show that higher land premiums increase transaction prices and volumes of nearby houses. Furthermore, developers with nearby land stocks consistently pay higher premiums in land auctions. We exploit a policy reform and implement various tests to support the hypothesis that developers strategically influence homebuyers’ expectations.
本研究探讨了中国土地和住房市场中家庭的外推型预期以及开发商的策略性应对机制。理论模型表明,当购房者形成房价上涨预期时,持有邻近地块的开发商会有策略地抬高土地竞拍价格,预期未来房价上涨将提升其现有土地储备的价值。通过利用土地拍卖时间的外生性特征,我们发现土地溢价上涨显著推高了周边住宅交易价格和成交量。实证结果显示,拥有邻近楼盘的开发商在土地拍卖中支付更高溢价。借助一项政策改革,我们通过多维度检验验证了"开发商有策略地影响购房者预期"这一假设。
