This paper studies the asset pricing implications of technology spillover, an important externality in innovation. While technology spillover enables firms to produce a variety of products that better satisfy their customers' love for variety, such benefits are procyclical, and investors...

We analyze the impact of international R&D spillovers on recipient countries in terms of social and private returns. We divide the aggregate R&D stock by the business, government and education sectors and examine the impact on Total Factor Productivity. We endogenize the accrual of the R&D...

We examine the effect of investor attention spillover on stock return predictability. Using a novel measure, the News Network Triggered Attention index (NNTA), we find that NNTA negatively predicts market returns with a monthly in(out)-of-sample R-square of 5.97% (5.80%). In the cross-section, a...

This paper empirically examines the effects of industrial and geographic innovations on firm-level profitability and stock returns due to spillovers. Using the data of U.S. patents and patent inventors, we propose empirical proxies for industrial and geographic spillovers and find a positive...

There is a large and growing literature on spillovers but no study that systematically evaluates the importance of spillovers for portfolio management. This paper provides such an analysis and demonstrates that spillovers are fully embedded in estimates of expected returns, variances, and...

We demonstrate that a firm's ability to innovate is predictable, persistent, and relatively simple to compute, and yet the stock market ignores the implications of past successes when valuing future innovation. We show that two firms that invest the exact same in research and development (R&D)...
