The R package quantreg.nonpar implements nonparametric quantile regression methods to estimate and make inference on partially linear quantile models. quantreg.nonpar obtains point estimates of the conditional quantile function and its derivatives based on series approximations to the...

We analyze how the legal enforceability of Noncompete Agreements (NCAs) affects labor markets. Using newly-constructed panel data, we find that higher NCA enforceability diminishes workers' earnings and job mobility, with larger effects among workers most likely to sign NCAs. These effects are...

We exploit the 2008 Oregon ban on non-compete agreements (NCAs) for hourly-paid workers to provide the first evidence on the impact of NCAs on low-wage workers. We find that banning NCAs for hourly workers increased hourly wages by 2-3% on average. Since only a subset of workers sign NCAs,...

We study whether firms value court enforceability of their workers’ noncompete agreements (NCAs), leveraging a 2020 Washington law that made NCAs unenforceable for workers earning less than a threshold of $100k per year (indexed to inflation), covering approximately 79% of Washing-ton workers....

Platforms often use fee discrimination within their marketplace (e.g., Amazon, eBay, and Uber specify a variety of merchant fees). To better understand the impact of marketplace fee discrimination, we develop a model that allows us to determine equilibrium fee and category decisions that depend...

This paper investigates the impact of price transparency on equilibrium prices and fees by considering a policy change implemented by Airbnb that affected the transparency of cleaning fees for IP addresses from the European Union (EU). Using a difference-in-differences approach, we find a...

We challenge the dichotomy of network effects and highlight that they are not an exogenous characteristic of networks, but endogenous to the decisions of network users. When users choose which activities to perform in a network, multi-activity users transform indirect into direct network...

Governments increasingly use changes in tax rules to combat evasion. We develop a general approach to point-identify tax compliance along with supply and demand elasticities; identification requires data on prices and quantities before and after changes in tax enforcement and a demand or supply...

We develop a model for two-sided markets with consumers and producers, who interact through a platform. Typical settings for the model are the market for smartphones with phone users, app producers, and smartphone operating systems; or the video game market with game players, video game...
