We present evidence about the ways that school superintendents add value in Israel's primary and middle schools. Superintendents are the CEOs of a cluster of schools with powers to affect the quality of schooling, and we extend the approach used in recent literature to measure teachers' value...

We study the relation between product quality and worker quality using an economic model that, under certain conditions, provides a direct link between product price, product quality and work force quality. Our measures of product quality are the evolution in the detailed product price relative...

On-demand labor platforms make up a large part of the “gig economy.” We quantify the extent of monopsony power in one of the largest on-demand labor platforms, Amazon Mechanical Turk (MTurk), by measuring the elasticity of labor supply facing the requester (employer) using both observational...

Streaming music services have exploded in popularity in the past few years, variously raising optimism and concern about their impacts on recorded music revenue. On the one hand, streaming services allow sellers to engage in bundling with the promise of increasing revenues, profits, and consumer...

Online labor markets have great potential as platforms for conducting experiments, as they provide immediate access to a large and diverse subject pool and allow researchers to conduct randomized controlled trials. We argue that online experiments can be just as valid - both internally and...

In most cities, the taxi industry is highly regulated and utilizes technology developed in the 1940s. Ride sharing services such as Uber and Lyft, which use modern internet-based mobile technology to connect passengers and drivers, have begun to compete with traditional taxis. This paper...

The “net neutrality” principle has triggered a heated debate and advocates have proposed policy interventions. In this paper, we provide perspective by framing issues in terms of the positive economic factors at work. We stress the incentives of market participants, and highlight the...

In several markets, firms compete not for consumer expenditure but instead for consumer attention. We model and characterize how households allocate their scarce attention in arguably the largest market for attention: the Internet. Our characterization of household attention allocation operates...

The large literature on costly signaling and the somewhat scant literature on preference signaling had varying success in showing the effectiveness of signals. We use a field experiment to show that even when everyone can send a signal, signals are free and the only costs are opportunity costs,...

The economic literature on online auctions is rapidly growing because of the enormous amount of freely available field data. Moreover, numerous innovations in auction-design features on platforms such as eBay have created excellent research opportunities. In this article, we survey the...
