This paper studies how search friction and spatial pricing can impact the taxi market in New York City. We use a mean field model, in which the taxi drivers strategically search for customers in different neighborhoods across the city, taking into account the spatial and temporal distribution of...

We study the relative effectiveness of administrative regulations, criminal enforcement, and civil lawsuits for combatting health care fraud. Between 2003 and 2017, Medicare spent $7.7 billion on 37.5 million regularly scheduled, non-emergency ambulance rides for patients traveling to and from...

This paper investigates different dynamics of two competing services, namely Uber, the app-based ride services and Borough (Green) Cab taxis, in the outer boroughs of New York City (NYC), focusing on the space and time distribution of their pick-up patterns. Uber is a new entrant to the taxi...

Self-employed workers provide useful evidence about the nature of flexible labor supply and possible reference-dependence. Many previous studies analyzed taxi cabdrivers. Newer rideshare platforms provide greater work hour flexibility and use surge pricing, making future marginal wages salient....

This study constructs a novel measure that aims to capture face-to-face private communications between firm managers and sell-side analysts by mapping detailed, large-volume taxi trip records from New York City to the GPS coordinates of companies and brokerages. Consistent with earnings releases...

We examine the impact of Articial 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...

Designing benefits for the growing platform workforce in the U.S. poses significant challenges. While platform workers need protection against unforeseen shocks, work that is often part time and spread across multiple platforms makes the traditional benefits model untenable. This paper reports...

In recent years, the rapid growth of peer-to-peer (p2p) ridesharing has significantly cut the market share and profitability for taxis, but taxis remain a major service provider in the personal-transportation service industry. This paper analytically examines a market with two segments of...

The disruptive effects of the sharing economy have received considerable attention from the press, researchers and policymakers. We empirically study whether and to what extent the entry of ridesharing programs (e.g., Uber) in a city changes the outcomes and behaviors of taxi drivers in that...
