What a lame article. I don't even see what the point is. It's just random whining that people in a certain field don't know all the answers. There wouldn't be much point in studying economics (or anything, for that matter) if all the problems were solved and everybody knew all the answers. There was an article on HN just the other day about Voyager 1 entering some unknown region of the universe. The physicists involved had no idea what was going on and all of their predictions turned out to be incorrect. So why no whiny article titled "Physics is a Lost Field"? Macroeconomics is hard. It's nearly impossible to perform experiments validating large scale macroeconomic theories. If there were a way to accurately test the impact of the government borrowing and spending money, then it would be carried out. But realistically there's no feasible way to do that. What's more, the author doesn't propose any solutions. Anybody can say this or that is screwed up. But that doesn't help anything. I'm sure the econ world would love to hear his theories that unquestionably solve the problems once and for all, but of course he didn't offer any. Also, his mention of Freakonomics has me doubting his understanding of economics. The sumo example he mentions is a pretty straightforward application of microeconomics. He then goes on to say, "Freakonomics is, however, silent on monetary or fiscal policy." Monetary and fiscal policy are macroeconomic concepts. Economics is about making decisions and choosing between alternatives - how will people spend their money, what will they choose in this situation, etc. There's more to econ than just growing the national economy.
