The current real-world economics review is now available free online. There are a couple of provocative short papers I liked by Nobel Laureates Ken Arrow and Joe Stiglitz. The Arrow piece argues that controversy over choice of the discount rate does not bring into question the conclusions of the Stern Review - for discount rates less than 8.5% the Stern's Review's conclusion that the benefits of mitigation exceed the costs are valid*. Stiglitz's piece builds on earlier attempts to build the Iraq war into a picture of the likely development of the global economy. He argues that a repeat of the stagflationary experiences of the 1970s and 1980s is a likely consequence of the war.
This is becoming a classy, readable, generalist journal and, as it is free, I recommend subscription to anyone vaguely interested in the economic view of our world.
*In the same issue an Aussi Ted Trainer takes issue with the Stern Review's estimates of the required extent of mitigation (Arow accepts this as accurate) claimimg it is a gross underestimate. To the contrary Trainer argues for a global abandonment of affluent enery-intensive lifestyles.
