Mobile internet devices reduce trading frictions and information search costs for investors, but also introduce attention-competing activities,such as social networking. We use exogenous nationwide and city-level outages of the Blackberry Internet Service (BIS) to investigate the effect of...

Does mobile internet distract “connected investors” from participating in financial markets? We examine this limited attention hypothesis using exogenous outages of the Blackberry Internet Service (BIS). We find that trading volume and trading frequency surge by 6% on days when BIS...

Under fairly general assumptions, expected stock returns are a linear combination of two accounting fundamentals ― book to market and ROE. Empirical estimates based on this relation predict the cross section of out-of-sample returns in 26 of 29 international equity markets, with a highly...

We provide the first large-scale study of the performance of expected-return proxies (ERPs) internationally. Analyst-forecast-based ICCs are sparsely populated and not robustly associated with future returns. Earnings-model-forecast-based ICCs are well-populated, but are unreliable outside the...
