Productivity Slowdown: Reducing the Measure of Our Ignorance
Growth accounting suggests that the bulk of the post-2004 slowdown in output growth in the U.S. is attributed to a residual called TFP. In this paper we provide a tractable accounting framework with firm heterogeneity to link this residual to innovations, markup dispersion, and potential measurement errors. Theories of creative destruction offer rich testable predictions of how the quality upgrading of products, the process efficiency of different firms, and markup dispersion in the market interact and therefore constitute a key approach to shed light on the slowdown in TFP growth.

Need for Speed: Quality of Innovations and the Allocation of Inventors
This paper studies how the speed-quality tradeoff in innovation interacts with firm dynamics, concentration, and economic growth. Empirically, we document long-run trends in the increasing speed of innovation alongside declining quality at large firms. Leveraging variation from an exogenous policy change, we document the existence of the speed-quality tradeoff both at the firm and aggregate level. We develop an endogenous growth model that incorporates the speed-quality tradeoff and show that allocating less labor towards speed increases growth, particularly in the presence of private ...
Technological Innovations and Global Trade of Services
Technological innovations may give the U.S. a significant advantage in the global trade of services, which could potentially help the U.S. close its trade deficit.

Goodfriend Memorial Lecture: Knowledge Creation and Diffusion
On May 11, 2023, Hugo Hopenhayn delivered the inaugural Marvin Goodfriend Memorial Lecture with a presentation of his paper "Knowledge Creation and Diffusion with Limited Appropriation," which was co-authored with Liyan Shi. The paper highlights how intellectual property rights must trade off incentives for innovation and knowledge diffusion and considers the optimal assignment of property rights as a Ramsey problem in a dynamic model where knowledge diffusion takes place under random matching. Hopenhayn is a professor of economics at UCLA, a Guggenheim Fellow and a long-term Richmond Fed ...

Connecting to Power: Political Connections, Innovation, and Firm Dynamics
How do political connections affect firm dynamics, innovation, and creative destruction? To answer this question, we build a firm dynamics model, where we allow firms to invest in innovation and/or political connection to advance their productivity and to overcome certain market frictions. Our model generates a number of theoretical testable predictions and highlights a new interaction between static gains and dynamic losses from rent-seeking in aggregate productivity. We test the predictions of our model using a brand-new dataset on Italian firms and their workers. Our dataset spans the ...

The Monetization of Innovation
We develop a dynamic model for digital service firms, which invest in monetization to generate revenues from services provided to customers for free. Our model captures and explains why such firms often build a large customer base and become highly valued while continuing to suffer losses—traditional models would struggle to explain this pattern. Counterfactual analysis reveals that monetization uncertainty slows technological advancement by diverting resources away from innovation. We also show that regulation aimed at protecting user privacy has sizable adverse effect on firm size and the ...

A Tax Plan for Endogenous Innovation
In times when elevated government debt raises concerns about dimmer global growth prospects, we ask: How can the government provide incentives for innovation in a fiscally sustainable way? We address this question by examining the Ramsey problem of finding optimal tax and subsidy schemes in a model in which growth is endogenously sustained by risky innovation. We characterize the shadow value of growth and entry in the innovation sector. We find that a profit tax is required to replicate the first-best in order to balance the externalities associated with innovative activity. At the ...

The Agglomeration of American Research and Development Labs
We employ a unique data set to examine the spatial clustering of about 1,700 private research and development (R&D) labs in California and across the Northeast corridor of the United States. Using these data, which contain the R&D labs? complete addresses, we are able to more precisely locate innovative activity than with patent data, which only contain zip codes for inventors? residential addresses. We avoid the problems of scale and borders associated with using fixed spatial boundaries, such as zip codes, by developing a new point pattern procedure. Our multiscale core-cluster approach ...

From Population Growth to TFP Growth
A slowdown in population growth causes a decline in business dynamism by increasing the share of old businesses. But how does it affect productivity growth? We answer this question by extending a standard business dynamics model to include endogenous productivity growth. Theoretically, the growth rate of the size of surviving old businesses is a “sufficient statistic" for determining the direction and magnitude of the impact of population growth on productivity growth. Quantitatively, this effect is significant across balanced growth paths for the United States and Japan. TFP growth in the ...
