Asset Pricing with Spatial Interaction
提出了空间资本资产定价模型和空间套利定价理论，将空间互动纳入经典资产定价模型，并应用于欧元区股票指数和房价指数期货，发现空间互动显著解释了横截面相关性。
We propose a spatial capital asset pricing model and a spatial arbitrage pricing theory (S-APT) that extend the classical asset pricing models by incorporating spatial interaction. We then apply the S-APT to study the comovements of eurozone stock indices (by extending the Fama–French factor model to regional stock indices) and the futures contracts on S&P/Case–Shiller Home Price Indices; in both cases, spatial interaction is significant and plays an important role in explaining cross-sectional correlation.
