This paper examines the relative merits of compact cities or urban sprawl (suburban settlement patterns) as a spatial solution to environmental problems (such as climate control), automobile dependence, economic development, infrastructure costs and the quality of urban life.

Scientific expertise suggests that mitigating extreme world-wide climate change damages requires avoiding increases in the world mean temperature exceeding 2° Celsius. To achieve the two degree target, the cumulated global emissions must not exceed some limit, the so-called global carbon...

I study climate policy choices for a 'policy bloc' of fuel-importers, when a 'fringe' of other fuel importers have no climate policy, fuel exporters consume no fossil fuels, and importers produce no such fuels. The policy bloc and exporter blocs act strategically in fossil fuel markets. When the...

We identify and examine a novel welfare channel of fuel economy standards through the in-teraction with public transit and households' location choices. A stricter emission standard for cars decreases the marginal cost of driving and triggers a shift in modal choice from public to private...

The long-term trend toward more work from home due to digitization has found a strong new driver, the Covid-19 pandemic. The profound change in urban mobility patterns supports the often-held view that reducing the number of commuting trips can lower carbon emissions to a certain degree. We...

Policy makers put great emphasis on the role of information about carbon emissions in achieving sustainable decisions by consumers. We conduct two studies to understand the optimal targeting of such information and its effects. First, we conduct an incentivized and representative survey among US...

The relative equity pricing of more climate-friendly ("green") versus less climate-friendly ("brown") companies is an open question in climate finance. Previous research comes to conflicting conclusions, documenting either a "carbon premium" with brown stocks yielding higher returns, or the...

Airline fuel consumption is costly for the firms and for society as well due to a climate-change externality. We study how fuel price changes affect cost-minimizing choices by airlines that have implications for the extent of this externality. The airline industry's capital stock can be easily...

We consider the question of how to integrate carbon emissions in comprehensive national accounts for the purpose of indicating whether countries' development is sustainable. We derive an expression for national saving which includes not only the national effect of current global emissions, but...

International trade is highly imbalanced both in terms of values and in terms of embodied carbon emissions. We show that the persistent current value trade imbalance patterns contribute to a higher level of global emissions compared to a world of balanced international trade. Specifically, we...
