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 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 use textual analysis of high-dimensional data from patent documents to create new indicators of technological innovation. We identify significant patents based on textual similarity of a given patent to previous and subsequent work: these patents are distinct from previous work but are...

We develop a general equilibrium model that delivers realistic fluctuations in both the level as well as the dispersion in executive pay as a result of changes in the technology frontier. Our model recognizes that executives add value to the firm not only by participating in production...

Using administrative data from the United States, we document novel stylized facts regarding technological innovation and the riskiness of labor income. Higher rates of industry innovation are associated with significant increases in labor earnings for top workers. Decomposing this result, we...

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...
