An Interoperability Framework for Payment Systems
Novel payment systems based on blockchain networks promise to redesign financial architecture, but a notable concern about these systems is whether they can be made interoperable. This concern stems from the concept of the “singleness of money”—that payments and exchange are not subject to volatility in the value of the money itself. Volatility and speculation can arise from the payment medium, which may have speculative characteristics, or from frictions that undermine the ability of one or more payments systems to interoperate. In this two-part series, we outline a framework for ...

Expanded GDP for Welfare Measurement in the 21st Century
The information revolution currently underway has changed the economy in ways that are hard to measure using conventional GDP procedures. The information available to consumers has increased dramatically as a result of the Internet and its applications, and new mobile communication devices have greatly increased the speed and reach of its accessibility. An individual now has an unprecedented amount of information on which to base consumption choices, and the “free” nature of the information provided means that the resulting benefits largely bypass GDP and accrue directly to consumers. ...

Foundational Processes and Growth
This paper studies the interaction between process and product innovations and their distinct role in firm growth dynamics. We differentiate empirically and theoretically two types of process innovations: foundational processes that advance production technology and cost-reducing processes that enhance existing production efficiency. We develop an innovation model of product varieties with quality heterogeneity to illustrate how these innovations affect firm growth differently and highlight how process innovation induces product innovation. By analyzing millions of patent texts from 1900 to ...

Evidence of Accelerating Mismeasurement of Growth and Inflation in the U.S. in the 21st Century
Corporate equity market values, profitability, and intangible investment have reached high proportions of income. Are these investments and their outcomes evidence of a wellfunctioning society? We do not see the rapid growth in aggregate measures of output that would justify these investments and rewards. And why did the yield curve invert as the U.S. federal funds rate reached 2⅜ percent in early 2019, if the inflation rate was near 2 percent? We present the broad case that mismeasurement of growth and prices accelerated in the U.S. during the 21st century and may be responsible for the ...

Measuring the “Free” Digital Economy Within the GDP and Productivity Accounts
We develop an experimental methodology that values ?free? digital content through the lens of a production account and is consistent with the framework of the national accounts. We build upon the work in Nakamura, et al. (2016) by combining marketing- and advertising-supported content and find that the impact of ?free? digital content on U.S. gross domestic product (GDP) has accelerated in recent years, particularly since 2005. However, the explosion in ?free? digital content is partially offset by a decrease in ?free? print content like newspapers. Including these, real GDP growth would grow ...

Transitional Dynamics in Aggregate Models of Innovative Investment
What quantitative lessons can we learn from models of endogenous technical change through innovative investments by firms for the impact of changes in the economic environment on the dynamics of aggregate productivity in the short, medium, and long run? We present a unifying model that nests a number of canonical models in the literature and characterize their positive implications for the transitional dynamics of aggregate productivity and their welfare implications in terms of two sufficient statistics. We review the current state of measurement of these two sufficient statistics and ...

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 ...

Technology Adoption and Leapfrogging: Racing for Mobile Payments
Paying with a mobile phone is a cutting-edge innovation transforming the global payments industry. However, some advanced economies like the U.S. are lagging behind in mobile payment adoption. We construct a dynamic model with sequential payment innovations to explain this puzzle, which uncovers how advanced economies' past success in adopting card-payment technology holds them back in the mobile-payment race. Our calibrated model matches the cross-country adoption patterns of card and mobile payments and also explains why advanced and developing countries favor different mobile payment ...

What Is the Equity-Efficiency Tradeoff when Maintaining Wells in Rural Haiti?
This paper quantitatively compares water infrastructure interventions that prioritize equity with those that prioritize efficiency. The community-based model developed by Haiti Outreach (HO) trains communities to operate and maintain wells, and has clear effi ciency gains over the status quo aid model in Haiti that gives communities wells: HO?s wells were 8.7 percentage points more likely to be functioning after one year than similarly-constructed wells managed under the status quo model. Because HO?s model includes user fees, which raise concerns about equity, I quantify the ...

Barriers to Creative Destruction: Large Firms and Nonproductive Strategies
This working paper reviews recent empirical evidence on large firms and nonproductivestrategies that hinder creative destruction and reallocation. The focus is on three types ofnonproductive strategies: political connections, nonproductive patenting, and anticompetitiveacquisitions. Across different contexts using granular micro data sets, we overwhelmingly see that asfirms gain market share, they increasingly rely on nonproductive strategies but reduce theirproductive, innovation-based strategies. I also discuss theoretical channels, aggregate implications,and potentials for some policies.
