Understanding Metro

Prince George’s County has updated its transportation plan to include an extension of Metro’s Green Line to Fort Meade (which, one imagines, would be a step toward its eventually extension to BWI). Matt has some good comments on the plan: [T]he key thing to keep in mind is that when you’re talking about new heavy […]

Paper of the Day

I’ve previously linked to research showing that while it’s not clear that sprawl leads to obesity, it does seem to be the case that the obese opt to live in sprawl, such that there is a correlation between the two. Here‘s something more on the connection: In this paper, we examine the effect of changes […]

On Geoengineering

Brad DeLong links to an interview with Ken Caldeira. It includes this: e360: Right. Well, a lot of people think of geoengineering as a quick and cheap fix for global warming. Is it? Caldeira: Let’s pretend for a moment that putting dust in the stratosphere is easy to do and works reasonably well… and that […]

The Need to Cut Emissions

Will Wilkinson quotes me arguing that geoengineering should be our last hope, for use after other plans, including emission cuts, have failed, and he writes: I’ve thought the matter through, but I still don’t understand this ordering of priorities.  I understand the strategic political motivation to make all potential technological fixes to global warming seem like wacky, […]

And he says: Why does Krugman keep doing this?  Why does he […]

Hydraulic Macro

I think these guys present some plausible scenarios about the way a downturn might unfold, and I […]

Paper of the Day

Available here. This is the abstract: This paper suggests a cause of low density in urban development or urban sprawl that has not been given much attention in the literature. There have been a number of arguments put forward for market failures that may account for urban sprawl, including incomplete pricing of infrstructure, environmental externalities, […]

Encouraging News of the Day

From Richard Layman: It happened that Matt Johnson was at the ACT monthly meeting on Tuesday, so we talked after. Matt is a blogger, both on his own blog, Track Twenty-Nine, and within Greater Greater Washington. Although Matt is “young,” he’s already probably forgotten more about fixed rail transit especially railroads, than I will ever […]
