We propose a new measure of the economic importance of each innovation. Our measure uses newly collected data on patents issued to US firms in the 1926 to 2010 period, combined with the stock market response to news about patents. Our patent- level estimates of private economic value are...

We develop a general equilibrium model of asset prices in which the benefits of technological innovation are distributed asymmetrically. Financial market participants do not capture all the economic rents resulting from innovative activity, even when they own shares in innovating firms. Economic...

Using a large sample of individual investor records over a nine-year period, we analyze survival rates, the disposition effect and trading performance at the individual level to determine whether and how investors learn from their trading experience. We find evidence of two types of learning:...

We provide a theoretical model linking firm characteristics and expected returns. The key ingredient of our model is technological shocks embodied in new capital (IST shocks), which affect the profitability of new investments. Firms' exposure to IST shocks is endogenously determined by the...

We explore the impact of investment-specific technology (IST) shocks on the crosssection of stock returns. IST shocks reflect technological advances embodied in new capital goods. Using a structural model, we show that IST shocks have a differential effect on the two fundamental components of...
