I generalize a benchmark model of directed technical change in order to reconcile it with the historical experience of energy transitions. I show that the economy becomes increasingly locked-in to the dominant sector when machines and energy resources are substitutes, but a transition away from...

Pigouvian taxes can fully correct for market failures due to externalities, but actual policies are commonly forced to deviate from the Pigouvian ideal due to administrative or political constraints. This paper derives sufficient statistics, which require a minimum of market information, that...

We designed and conducted three randomized control trials in partnership with a large biopharmaceutical company operating over 160 plasma donation centers, with the aim of promoting sustainable behaviors in a workplace setting. Specifically, we focused on reducing operational errors that led to...

Society's transition toward more sustainable energy sources is well underway. But substantially reducing the use of fossil fuels to generate electricity, to power vehicles, and to manufacture the stuff of everyday life will profoundly disrupt the communities that currently dedicate themselves to...

Can simple government programs effectively promote voluntary initiatives to reduce greenhouse-gas emissions? This paper provides an evaluation of how the Connecticut Clean Energy Communities program affects household decisions to voluntarily purchase "green" electricity, which is electricity...

"Nudges" are being widely promoted to encourage energy conservation. We show that the popular electricity conservation "nudge" of providing feedback to households on own and peers' home electricity usage in a home electricity report is two to four times more effective with political liberals...

Our new analytical general equilibrium model is used to study effects of tightening state Renewable Portfolio Standards (RPS) on electricity price, CO2 emissions, fossil fuel electricity generation, and two kinds of renewable generation. We show how those outcomes depend on key state...

We analyse the importance of climate-related investment using a large economy-wide survey of UK firms. Over half of firms expect climate change to have a positive impact on their investment in the medium term, with around a quarter expecting a large impact of over 10%. Around two-thirds of these...

Energy efficiency and conservation are considered key means for reducing greenhouse gas emissions and achieving other energy policy goals, but associated market behavior and policy responses have engendered debates in the economic literature. We review economic concepts underlying consumer...
