Decentralized Finance (DeFi): Transformative Potential and Associated Risks
Financial services in the crypto finance world are provided by a combination of centralized finance (CeFi) organizations and decentralized finance (DeFi). CeFi's are roughly similar to traditional financial intermediaries, but DeFi seeks to provide services using smart contracts (computer code) rather than an intermediary. DeFi's unusual structure creates some interesting potential but also raises new risks in addition to those already inherent in blockchains and crypto finance. This paper reviews some of the opportunities and risks.

Limited enforcement and the organization of production
This paper describes a dynamic, general equilibrium model designed to assess whether contractual imperfections in the form of limited enforcement can account for international differences in the organization of production. In the model, limited enforcement constrains agents to operate establishments below their optimal scale. As a result, economies where contracts are enforced more efficiently tend to be richer and emphasize large scale production. Calibrated simulations of the model reveal that these effects can be large and account for a sizeable part of the observed differences in the size ...

What makes a job better? Survey evidence from job changers
Changes in pay and benefits alone incorrectly predict self-assessed changes in overall job quality 30 percent of the time, according to survey evidence from job changers. Job changers also place more emphasis on their interest in their work than they do on pay and benefits in evaluating whether their new job is better. Parents particularly emphasize work-life balance, and we find some indications that mothers value it more than fathers. Improvements in pay are highly correlated with improvements in other amenities for workers with less education but not for workers with a bachelor's degree or ...

Financial Crises and the Global Supply Network: Evidence from Multinational Enterprises
This paper empirically examines the effects of financial crises on the organization of production of multinational enterprises. We construct a panel of European multinational networks from 2003 through 2015. We use as a financial shock the increase in risk premia between August 2007 and July 2012 and build a multinational-specific shock based on the network structure before the shock. Multinationals facing a larger financial shock perform worse in terms of revenue, employment, and growth in the number of affiliates. Lower growth in the number of affiliates operates through a negative effect ...

Heterogeneity in Work from Home: Evidence from Six U.S. Datasets
This article documents heterogeneity in work from home (WFH) using six nationally representative U.S. surveys. These surveys show consistent patterns indicating that pre-pandemic differences in WFH rates by sex, education, and state of residence expanded following the COVID-19 outbreak. The surveys also show similar post-pandemic trends in WFH by firm size and industry. We find that an industry’s WFH potential was highly correlated with actual WFH during the first year or two of the COVID-19 pandemic. However, this correlation was much weaker before and after, suggesting that WFH potential ...

Measuring Trends in Work from Home: Evidence from Six U.S. Datasets
This article documents the prevalence of work from home (WFH) using six nationally representative U.S. surveys. These surveys measure WFH using different questions, reference periods, samples, and survey collection methods. After constructing comparable samples and WFH measures across surveys, we find that the surveys show broadly similar trends in the trajectory of aggregate WFH since the COVID-19 outbreak. The most important source of disagreement in WFH levels across surveys is in WFH by self-employed workers; by contrast, WFH rates for employees are closely aligned across surveys. All ...

Measuring Trends in Work From Home: Evidence from Six U.S. Datasets
This paper documents the prevalence of work from home (WFH) in six U.S. data sets. These surveys measure WFH using different questions, reference periods, samples, and survey collection methods. Once we construct samples and WFH measures that are comparable across surveys, all surveys broadly agree about the trajectory of aggregate WFH since the Covid-19 outbreak. The most important source of disagreement in the level of WFH across surveys is in WFH by self-employed workers; by contrast, surveys closely agree on rates of WFH among employees. All surveys agree that in 2024 WFH remains ...

Mapping a Sector’s Scope Transformation and the Value of Following the Evolving Core
A surprisingly neglected facet of sector evolution is the evolutionary analysis of firms’, and thus a sector’s, scope. Defining a sector as a group of firms that can change their scope over time, we study the transformation of U.S. banking firms. We undertake a sectoral, population-wide study of business-scope transformation, with particular focus on which segments banks expand into. As financial intermediation evolved, a continuously shifting set of activities became associated with “core banking,” with scope changing and relatedness itself (measured through coincidence) evolving ...
