Innovation and growth with financial, and other, frictions
The generation and implementation of ideas, or knowledge, is crucial for economic performance. We study this process in a model of endogenous growth with frictions. Productivity increases with knowledge, which advances via innovation, and with the exchange of ideas from those who generate them to those best able to implement them (technology transfer). But frictions in this market, including search, bargaining, and commitment problems, impede exchange and thus slow growth. We characterize optimal policies to subsidize research and trade in ideas, given both knowledge and search externalities. ...

Should Central Banks Worry About Facebook's Diem and Alibaba's Alipay?
Alibaba — an e-commerce platform in China similar to Amazon — has created its own payment system (Alipay) to provide currency-like services: facilitating transactions, supporting peer-to-peer transfers and paying interest.

What drives platforms to develop their own digital currency rather than use existing cash and card options? And should central banks and financial regulators worry about platforms issuing their own currency?

Payments on Digital Platforms: Resiliency, Interoperability and Welfare
Digital platforms, such as Alibaba and Amazon, operate an online marketplace to facilitate transactions. This paper studies a platform’s business model choice between accepting cash and issuing tokens, as well as the implications for welfare, resiliency, and interoperability. A cash platform free rides on the existing payment infrastructure and profits from collecting transaction fees. A token platform earns seigniorage, albeit bearing the costs of setting up the system and holding reserves to mitigate the cyber risk. Tokens earn consumers a return, insulating transactions from the ...

What Is a Crypto Conglomerate Like FTX? Economics and Regulations
We explain the economics behind the rise and fall of FTX. We view FTX and its associates as components making up one large entity: a crypto conglomerate. Understanding the economics of crypto conglomerates is crucial for designing effective regulations.
