Can Mitigating Global Climate Change be a Free Lunch?

September 30, 2014 by Matthew Stepp

Krugman and Climate Change Mitigation Costs

Paul Krugman launched the latest salvo in the battle over the economics of climate change when he recently announced: “Saving the planet would be cheap; it might even be free.” But he ignores critical nuances on policy and technology that lead him to the wrong conclusion that climate mitigation is a free lunch.[read more]

Krugman: In The Real War On Coal, The Mining Industry Won And Workers Lost

June 14, 2014 by Joseph Romm

The War on Coal and the War on Workers

If conservatives truly cared about coal miners they wouldn’t work so hard to block coal dust reforms — an action that United Mine Workers President Cecil Roberts said in 2012 “amounts to nothing more than a potential death sentence for thousands of American miners.”[read more]

Krugman: Climate Action Is 'Remarkably Cheap,' New EPA Rules Would Give 'U.S. Economy A Boost'

June 1, 2014 by Joseph Romm

Climate Action at Low Cost

What would be the cost to the U.S. of moderate carbon pollution reductions, such as the emissions standards for existing power plants that the EPA will be announcing shortly? It’s a question that we always had to answer since the EPA is legally obligated to issue rules regulating CO2.[read more]

When Economic Recovery Collides with Flat Oil Production

January 11, 2011 by Robert Rapier

A theme that I commonly discuss in articles and presentations is the problem of economic recovery when oil prices are high. If the market is well-supplied and there is ample excess oil production capacity, oil prices tend to be moderate and stable, and economic growth can proceed without much headwind. However, the world has now had...[read more]

Drill, Baby, Drill: Drill the bottomless well

May 5, 2010 by A Siegel

Paul Krugman’s Drilling, Disaster, Denial is both a great OPED piece to see in the traditional media and, well, a troubling read. Great because of its focus on how one of environmentalism greatest problems might, in fact, have been its successes which could have helped lead to complacency in the public, undermining efforts to build...[read more]

Krugman explains environmental economics

April 8, 2010 by Lou Grinzo

Paul Krugman, a man whose work I admire for its pedagogical value as well as its chance of being the one thing on this planet that makes economics and economists cool, has a long piece in the NY Times about environmental economics. To say it’s worth your time to read the whole thing would be a laughable understatement. So ignore...[read more]

Crude oil prices in 2008: Was the spike a bubble?

March 31, 2010 by Michael Giberson

In the physical world, spikes and bubbles are quite different things that don’t generally get mistaken for one another.  Curiously, in economic metaphor, the same phenomena can be called a spike and a bubble.  Argument among economists continues on the issue of whether the oil price spike in 2008 was or wasn’t a bubble. A few...[read more]

Benefits and costs of energy efficiency investments

December 31, 2009 by John Whitehead

Ryan Avent and Paul Krugman are ripping Ted Gayer over his recognition of the costs of energy efficiency investments. Here is Krugman:Ryan Avent takes on Ted Gayer so I don’t have to. Mr. Gayer tries to dismiss some of what I’ve said about the cost of climate-change policy by mocking a McKinsey study showing that a substantial amount of...[read more]

Energy gaps - Paul Krugman Blog

December 30, 2009 by John Whitehead

Ryan Avent takes on Ted Gayer so I don’t have to. Mr. Gayer tries to dismiss some of what I’ve said about the cost of climate-change policy by mocking a McKinsey study showing that a substantial amount of conservation would actually save money, that is, have a negative cost. But Ryan is actually too kind. Gayer doesn’t just have a...[read more]

That's not quite right, is it? (part 1)

December 7, 2009 by John Whitehead

I agree with this from today's Krugman:...cutting greenhouse gas emissions is affordable as well as essential. Serious studies say that we can achieve sharp reductions in emissions with only a small impact on the economy’s growth. However:Action on climate, if it happens, will take the form of “cap and trade”: businesses won’t be told...[read more]

Nobelist Krugman on Copenhagen: “A deal there would save the planet at a price we can easily afford — and it would actually help us in our current economic predicament.”

December 7, 2009 by Joseph Romm

Still, should we be starting a project like this when the economy is depressed? Yes, we should — in fact, this is an especially good time to act, because the prospect of climate-change legislation could spur more investment spending. Consider, for example, the case of investment in office buildings. Right now, with vacancy rates soaring...[read more]

How to create 1.7 million clean energy jobs

December 2, 2009 by Joseph Romm

The challenges facing President Obama and the U.S. Congress have not gone away. Paul Krugman worries that “unemployment is likely to stay near its current level for a year or more,” because “much of the political establishment now sees stimulus as having been discredited by events, so that it’s very hard to come back and scale the...[read more]

Harvard Business Review: SuperFreakonomics Ignores the Business Case for Sustainability

October 28, 2009 by Joseph Romm

The error-riddled book Superfreakonomics got the economics dead wrong, too, as Nobelist Krugman and others have noted.  Now Harvard Business Review weighs in on how they got the business side wrong.  I’m reposting an HBR piece by Andrew Winston, co-author of the best-seller Green to Gold and the author of the new book Green...[read more]

Economists Debate Waxman-Markey. Yuck.

September 29, 2009 by John Whitehead

Ah! Liberals versus conservatives, economists criticized for their politics … don’t you love the economic debate over … the cap-and-trade part of Waxman-Markey. Did you think I was going to say “economic stimulus” or “health care”?Paul Krugman, in his September 24th column (“It’s easy being green”), rips those he disagrees with...[read more]

Is Krugman being completely above board?

September 28, 2009 by Tim Haab

In reference to Paul Krugman's NYTimes piece yesterday on the basic economics of cap and trade, I received this e-mail from a colleague in Statistics at Ohio State:Is Krugman being completely above board?My reply:First, I'll state I'm not a big fan of Krugman's political commentary.  With that said, he pretty much nails this basic...[read more]
