Technological innovation in medical services can improve health, but its ability to reach patients often depends on price signals for downstream providers, which can also be discordant across production inputs. We examine such a context when Medicare sharply revises facility fees--while holding...

Reducing gender-specific commuting barriers in developing countries has complex and diverse effects on women's labor dynamics. We study a program that offers free bus rides for women in several Indian states (the Pink Slip program) using a synthetic difference-in-differences approach to shed...

Following Uber-initiated fare increases, drivers make more money per trip and, initially, more per hour-worked. Drivers begin to work more hours. However, this increase in hours-worked--combined with a reduction in demand from a higher fare--has a business stealing effect, with drivers spending...

This paper considers the evolution of global transportation usage over the past half century and its implications for supply chains. Transportation usage per unit of real output has more than doubled as costs decreased by a third. Participation of emerging economies in world trade and...

We examine the impact of Artificial Intelligence (AI) on productivity in the context of taxi drivers. The AI we study assists drivers with finding customers by suggesting routes along which the demand is predicted to be high. We find that AI improves drivers' productivity by shortening the...

The social costs of pollution and climate change hinge critically on humans' ability to adapt. Based on transaction records from the world's largest payment network, this research compiles daily travel flows and documents that China's rapid expansion of high-speed railways (HSR) facilitates the...

We quantify the commute time savings associated with work from home, drawing on data for 27 countries. The average daily time savings when working from home is 72 minutes in our sample. We estimate that work from home saved about two hours per week per worker in 2021 and 2022, and that it will...

Economic activity is highly unevenly distributed within cities, as reflected in the concentration of economic functions in specific locations, such as finance in the Square Mile in London. The extent to which this concentration reflects natural advantages versus agglomeration forces is central...

The sharing economy for a wide range of goods and services is expanding across the world. To direct the benefits from sharing capital services towards small-scale producers, governments in the developing world are increasingly intervening in fast-growing mechanization rental markets. However,...
