We analyze the supply-side disruptions associated with Covid-19 across firms and workers. To do so, we exploit differences in the ability of workers across industries to work remotely using data from the American Time Use Survey (ATUS). We find that sectors in which a higher fraction of the...

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 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 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...

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 present a model of optimal allocation over liquid and illiquid assets, where illiquidity is the restriction that an asset cannot be traded for intervals of uncertain duration. Illiquidity leads to increased and state-dependent risk aversion, and reduces the allocation to both liquid and...

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...

This paper provides evidence that risk aversion leads pharmaceutical firms to underinvest in radical innovation. We define a drug candidate as novel if it is molecularly distinct from prior candidates. Using our measure, we show that firms face a risk-reward tradeoff when investing in novel...

We provide new evidence that a disruption in credit supply played a quantitatively significant role in the unprecedented contraction of employment during the Great Depression. To analyze the role of financing frictions in firms' employment decisions, we use a novel, hand-collected dataset of...
