Although spatial techniques have been used to capture the spillovers in asset returns across different regions, they have not yet been applied in an asset pricing context. Combining asset pricing models and equilibrium spatial models can be a good way to disentangle spillover effects across assets thereby accounting for systemic risks. We use an innovative approach and estimate a four-factor ‘Spatial’ Capital Asset Pricing Model (SCAPM) which allows us to account for correlations in the error terms. We can account for direct or indirect spillover effects in the presence of increased spillovers through the idiosyncratic component or of increased spillovers through the market respectively. We find that contagion dramatically increases during the global financial crisis and the spillover effect can explain up to 40% of total asset variation. In the rest of the time, idiosyncratic risks have been the predominant type of risk in real estate stocks. Our results have implications for investors showing that the market can channel asset volatility leading to contagion during crisis periods and therefore residual linkages between country indices need to be accounted for as a means of assessing the diversification benefits of a global portfolio.
