We apply a Regression Discontinuity based approach to screen for collusion developed in Kawai et al. (2022) to public procurement data from five countries. We find that bidders who win by a very small margin have significantly lower backlog than those who lose by a very small margin in the...

We examine the effect of school traffic pollution on student outcomes by leveraging variation in wind patterns for schools the same distance from major highways. We compare within-student achievement for students transitioning between schools near highways, where one school has had greater...

In this chapter we draw from existing literature and a range of statistics to describe economic, entrepreneurial and innovative activities in the transportation and warehousing sector of the U.S. economy. We suggest multiple avenues for future work, and argue for more research on the role of...

This is a comprehensive study of measurement and substantive issues that arise in determining the rate of multi factor productivity (MFP) growth in the transportation industry over the postwar period, 1948-87. Official data on output and employment are provided by two government agencies and...

We develop a spatial model of energy exploitation where energy sources are differentiated by their geographic location and energy density. The spatial setting creates a scaling law that magnifies the importance of differences across energy sources. As a result, renewable sources twice as dense,...

The United States consumed more petroleum-based liquid fuel per capita than any other OECD-high-income country - 30 percent more than the second-highest country (Canada) and 40 percent more than the third-highest (Luxemburg). This paper examines the main channels through which reductions in U.S....

We analyze the organization of corruption in a state agency. The dual mandate of the Democratic Republic of the Congo's traffic police agency is to manage traffic and to enforce the traffic code. We first document that, in the capital's branch, Kinshasa, traffic violation fines account for only...

Replacing fossil fuels in the name of decarbonization is necessary but will be particularly difficult due to their as-yet unrivaled bundle of attributes: abundance, ubiquity, energy density, transportability and cost. There is a growing commitment to electrification as the dominant...

We examine a statewide program that identifies police departments with large racial disparities in traffic stops and works with identified departments to reduce disparities. The intervention caused large (23.56%) and persistent (at least 12 months) reductions in the number of minorities involved...
