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 ...

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.

International R&D Spillovers and Asset Prices
We study the international propagation of long-run risk in the context of a general equilibrium model with endogenous growth. Innovation and international diffusion of technologies are the channels at the core of our mechanism. A calibrated version of the model matches several asset pricing and macroeconomic quantity moments, alleviating some of the puzzles highlighted in the international macro-finance literature. Our model predicts that country-pairs that share more R&D have less volatile exchange rates and more correlated stock market returns. Using data from a sample of 19 developed ...

The Making of an Economic Superpower―Unlocking China’s Secret of Rapid Industrialization
The rise of China is no doubt the most important event in world economic history since the Industrial Revolution. The institutional theory of development based on a dichotomy of extractive vs. inclusive political institutions cannot explain China?s rise. This article argues that only a radical reinterpretation of the history of the Industrial Revolution and the rise of the West (as incorrectly portrayed by the institutional theory) can fully explain China?s growth miracle and why the determined rise of China is unstoppable. Conversely, China?s spectacular and rapid transformation from an ...

Valuing \"Free\" Media in GDP: An Experimental Approach
?Free? consumer entertainment and information from the Internet, largely supported by advertising revenues, has had a major impact on consumer behavior. Some economists believe that measured gross domestic product (GDP) growth is badly underestimated because GDP excludes online entertainment (Brynjolfsson and Oh 2012; Ito 2013; Aeppel 2015). This paper ntroduces an experimental GDP methodology that includes advertising-supported media in both final output and business inputs. For example, Google Maps would be counted as final output when it is used by a consumer to plan vacation driving ...
