This paper measures for the first time the economic efficiency effects of the taxation of wireless services, which are taxed by federal, state, and local governments at relatively high rates in the range of 14%-25%. The paper concludes such taxes are a much greater drain on the economy than...

We study the effect of information on technology adoption and productivity in agriculture. Our empirical strategy exploits the expansion of the mobile phone network in previously uncovered areas of rural India coupled with the availability of call centers for agricultural advice. We measure...

We calculate the social return on algorithmic interventions (specifically their Marginal Value of Public Funds) across multiple domains of interest to economists--regulation, criminal justice, medicine, and education. Though these algorithms are different, the results are similar and striking....

Fatal school shootings often spark support for stricter gun laws, threatening the gun lobby's influence and agenda. To prevent political fallout, do pro-gun Political Action Committees increase contributions after fatal school shootings? Leveraging a novel dataset of pro-gun PAC contributions...

This paper investigates the tradeoff between competition and financial inclusion resulting from the vertical integration between mobile network and money operators. Joining newly assembled data on mobile money fees through the WayBack machine, with sources on network coverage and financials, we...

Mental health disorders account for a significant share of the overall global disease burden. The economic losses from such disorders are staggeringly large, particularly in low-income countries, where people are faced with several unexpected shocks. We test whether improved communication can...

The combinatorial clock auction is becoming increasingly popular for large-scale spectrum awards and other uses, replacing more traditional ascending or clock auctions. We describe some surprising properties of the auction, including a wide range of ex post equilibria with demand expansion,...

This paper describes a field experiment in Oklahoma City Public Schools in which students were provided with free cellular phones and daily information about the link between human capital and future outcomes via text message. Students' reported beliefs about the relationship between education...

We evaluate the impact of a health information intervention implemented through mobile phones, using a clustered randomized control trial augmented by qualitative interviews. The intervention aimed to improve sexual health knowledge and shift individuals towards safer sexual behavior by...

Cellular technologies have become increasingly important in the developing world; infrastructure for mobile networks has expanded dramatically over the past two decades giving access to remote areas without previous phone service. Despite this expansion, relatively little is known about the...
