This paper models the attention allocation of portfolio investors. Investors choose the composition of their information subject to an information flow constraint. Given their expected investment strategy in the next period, which is to hold a diversified portfolio, in equilibrium investors...

This paper explores the joint determination of home bias and attention allocation. We overcome the typical challenge associated with evaluating attention allocation theories by using a new internet search query dataset to measure how much information investors decide to process. Employing an...

This paper shows that imperfect financial integration and informational asymmetries are not competing theories but rather complementary ideas to a single explanation of the home bias puzzle. We develop a rational expectations model of asset prices with investors that face informational...

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...

We add quality uncertainty to a two-country trade model with CES preference and monopolistic competition. There are two kinds of firms - low quality and high quality. Quality is perfectly observable in the domestic market but not in the foreign market. Exporters use price to signal their...

This paper explains financial contagion between two stock markets with uncorrelated fundamentals by fluctuations in international investors’ attention allocation. We model the process of attention allocation that underlies portfolio investment in international markets using investors who face...

Uncertainty about product quality is endemic in international trade. We develop a dynamic, two country model where home producers differ in terms of the quality of the products they sell. This quality is imperfectly observed by foreign consumers initially but known once the product is consumed....

We propose a model of delegated asset management that can explain the following empirical regularities in international markets: the presence of home bias, the lower proportion of mutual funds investing domestically, and the higher market value of mutual funds investing domestically. In the...
