In the finance literature, statistical inferences for large-scale testing problems usually suffer from data snooping bias. In this paper we extend the "superior predictive ability" (SPA) test of Hansen (2005, JBES) to a stepwise SPA test that can identify predictive models without potential data...

In an economy with time-varying investment opportunities, the changes in technology prospects affect aggregate consumption and individual firm's future dividends, and lead to systematic technology risk. We construct a technology factor to track the changes in technology prospects measured by...

In this paper, I propose that technological innovations increase expected stock returns and premiums at the aggregate level. I use aggregate patent data and research and development (R&D) data to measure technological innovations in the U.S., and find that patent shocks and R&D shocks have...

In this article we reexamine the profitability of technical analysis using White's reality check and Hansen's SPA test that correct the data snooping bias. Compared to previous studies, we study a more complete "universe" of trading techniques, including not only simple rules but also complex...

One unique feature of the emerging economies in Asia is the rich variation in the development of financial systems and technological sectors across different geographical areas. This unbalanced evolution provides us a potentially more powerful setting to investigate the dynamics among banking...

In this paper, we re-examine the profitability of technical analysis using the Reality Check of White (2000, Econometrica) that corrects the data snooping bias. Comparing to previous studies, we study a more complete “universe” of trading techniques, including not only simple trading rules...

According to conventional wisdom, family ownership, which signals a lack of social capital and trust in an economy, may impede innovation. This argument, however, fails to recognize that modern family firms can benefit from capitalist institutions that promote innovation. Using a comprehensive...

We propose that owing to limited investor attention and skepticism of complexity, firms with greater innovative originality (IO) will be undervalued, especially for firms with higher valuation uncertainty, lower attention, and greater sensitivity of future profitability to IO. We find that IO...
