Extrapolative households and strategic firms: Evidence from China’s land and housing market
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 transac…
