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...

This paper considers the evolution of global transportation usage over the past half century and its implications for supply chains. Transportation usage per unit of real output has more than doubled as costs decreased by a third. Participation of emerging economies in world trade and...

Economic policies often involve dynamic interventions, where individuals receive repeated interventions over multiple periods. This dynamics makes past responses informative to predict future responses and ultimate outcomes depend on the history of interventions. Despite these phenomena,...

The phasedown of coal for electricity generation is considered vital to meeting global climate targets. Many countries have pledged to stop using coal, with some as early as 2030. While the United States has no target currently in place, several states do. In this paper, we examine the...

Advocates in several countries have promoted a "green recovery" from the pandemic, with an emphasis on measures to address climate objectives. We evaluate proposals for the United States and find that as stated, ambitious plans to further cut emissions from transportation and electricity will...

Efforts to reduce carbon emissions significantly will require considerable improvements in energy intensity, the ratio of energy consumption to economic activity. Improvements in energy intensity over the past thirty years suggest great possibilities for energy conservation: current annual...

Improving end-use energy efficiency--that is, the energy-efficiency of individuals, households, and firms as they consume energy--is often cited as an important element in efforts to reduce greenhouse-gas (GHG) emissions. Arguments for improving energy efficiency usually rely on the idea that...

Utilizing theory and empirical insights from psychology and behavioral economics, this paper examines individuals' cognitive and motivational barriers to adopting climate change adaptation and mitigation measures that increase consumer welfare. We explore various strategies that take into...

Building energy efficiency has been a cornerstone of greenhouse gas mitigation strategies for decades. However, impact evaluations have revealed that energy savings typically fall short of engineering model forecasts that currently guide funding decisions. This creates a resource allocation...

Transportation infrastructure is vital for the smooth functioning of international trade. Ports are a crucial gateway to this system: with more than 80% of trade carried by ships, they shape trade costs, and it is critical that they operate efficiently. Yet ports are susceptible to disruptions,...
