More on Laffer's math
I guess that most of my readers have noticed that I have been somewhat upset by Arthur Laffer's attempt to demonstrate that fiscal stimulus doesn't work. While I am certainly very skeptical about how fruitful fiscal stimulus will be I was not impressed with Laffer's "evidence" that fiscal stiumulus does not work. I did, however, not plan to write more on this - as I certainly do not want to promote fiscal easing anywhere and find this fiscal issue somewhat boring and irrelevant for understanding the present crisis - but then I got an interesting email from Jim Allbery. Jim is not an economist, but a software developer with a degree in math. Jim had been equally upset by the bad math in Laffer's Wall Street Journal piece as I had been and Jim actually has taken a closer look at Laffer's math. Jim sent me a note on his considerations about Laffer's math. I think Jim's note is rather interesting and Jim has kindly allowed me to publish it. So here is Jim's comment on Bad Math in the WSJ Finally, just to get my position clear. I believe there is a rather significant need for fiscal consolidation in both the US and the euro zone. There is therefore no room for fiscal easing in the US or in most euro zone countries. However, the fiscal position is being made worse by overly tight monetary policy, which seriously depresses growth in both the US and the euro zone. I therefore agree with Laffer that fiscal stimulus is not the way forward in the present situation. However, I am no Calvinist and I do not believe that our present problems are due to bad fiscal policies, but rather due to overly tight monetary policy. ---- Related posts: Arthur Laffer you’re embarrassing yourself More on Laffer and Estonia – just to get the facts right “Meantime people wrangle about fiscal remedies” There is no such thing as fiscal policy David Glasner's posts on Laffer's math: Arthur Laffer, Anti-Enlightenment Economist A Laffer Postscript
