This paper provides suggestive evidence of financial contagion between regions by fluctuations in international investors' attention allocation. Using Financial Times news stories about Thailand as a proxy for attention allocated to Southeast Asia, we find that the increase in uncertainty about...

This paper explains financial contagion between two independent stock markets by fluctuations in international investors' attention allocation. I model the process of attention allocation that underlies portfolio investment in international markets using rationally inattentive agents. Investors...

This paper presents a rational expectations model of asset prices with rationally inattentive investors that, unlike previous papers, can explain both the substantial amount of equity wealth invested domestically and the puzzling time series behavior of the home bias - an initial plateau before...
