史綱教授於1992年在本期刊所發表的論文，將預售屋定價的學術研究帶入一個新的里程碑。本文擴展該文理論模型設定，允許預售屋的買方在支付頭期款或訂金後，擁有放棄履約的權利，並以本文模型重新檢視該文實證結果，結果發現出本文模型預測結果優於史綱教授之模型。另外，就本文分析結果也證明了史綱教授該文結論的頑強性。

This journal published Shyy’s pioneering research on pricing model for the per-sales housing in 1992. The purpose of this study is to extend Shyy’s model and allows buyers have rights to give up the contract after paying their initial up-front payment. Using Shyy’s data, we find that our model’s prediction power is better than Shyy’s model. In addition, our results support Shyy’s comparative static results.
