Scholars of voting behavior are often confronted with poor data availability or unsuitably large units of aggregation for reported turnout. We demonstrate a big-data solution to this challenge, using fine-grained cell-phone mobility data on millions of GPS locations for more than 300,000...

The Simultaneous Multiple Round Ascending Auction (SMRA) pioneered by Milgrom, Wilson and McAfee in 1994 has become a defacto standard auction mechanism for the award of radio spectrum for commercial mobile services around the world. The winning bid price in such SMRA spectrum auctions is of...

It is generally accepted that a "global chain"-orchestrated by a lead firm-is the relevant unit of analysis for research on contemporary global industries. However, our research shows that value chains (GVCs) and supply chains (GSCs) are only segments of the massively complex "ecosystem of...

Digital technologies (DTs) are becoming an important mechanism for unleashing inclusive development, particularly across Africa. The rollout of mobile broadband internet (3G) coverage has expanded substantially in several African countries; however, digital divides persist across various groups....

Estimating the extent to which transportation contributes to air pollution levels has been hampered by the difficulty in separating the relative degree of ambient nitrogen dioxide generated by transportation, power generation, and industrial activity'all of which play roles. This paper addresses...

Can mobile phone data improve program targeting By combining rich survey data from the baseline of a "big push" anti-poverty program in Afghanistan implemented in 2016 with detailed mobile phone logs from program beneficiaries, this paper studies the extent to which machine learning methods can...

Digital technologies can expand access to health services to underserved populations. This paper leverages mobile network expansion and survey data spanning two decades to study the impact of access to mobile phones on infant mortality in Africa. Using plausibly exogenous variations in lightning...

The deep economic transformation of India will be accompanied by rapid growth in passenger and freight demand and require a transition to more sustainable transport solutions. In this context, electric mobility (e-mobility) is anticipated to play a major role in India's transport transition...
