Introduction Definitions and Basics

●      Efficiency, by Paul Heyne, from the Concise Encyclopedia of Economics

●      To economists, efficiency is a relationship between ends and means. When we call a situation inefficient, we are claiming that we could achieve the desired ends with less means, or that the means employed could produce more of the ends desired….

●      New Keynesian Economics, by N. Gregory Mankiw, from the Concise Encyclopedia of Economics

●      The heart of the new synthesis is the view that the economy is a dynamic general equilibrium system that deviates from an efficient allocation of resources in the short run because of sticky prices and perhaps a variety of other market imperfections….

●      Efficient Capital Markets, by Steven L. Jones and Jeffry M. Netter, from the Concise Encyclopedia of Economics

●      Who Loses from Efficiency?, by Bryan Caplan. EconLog.

●      During last night’s debate, Robin repeated an argument many economists have made: In the long-run, maximizing efficiency is actually better for everyone.� If we consistently adopt any policy with benefits greater than costs, then the times that you win will outweigh those that you lose, so you’ll be better off on net.� Optional escape hatch: Even if you don’t happen to win on net, you can still ex ante expect to win on net; efficiency raises everyone’s expected well-being.

●      When I give my lecture on efficiency, I always point out how crazy this claim is.� “Everyone” means everyone.� The world has over six billion people.� Some of them have really weird preferences; a subset of these people with weird preferences are already extremely satisfied.� Is it really likely–or even credible–that every single one of these people would be better off if we junked all inefficient policies?…

A Little History: Primary Sources and References

●      Lionel Robbins, biography, from the Concise Encyclopedia of Economics

●      Robbins’ most famous book was An Essay on the Nature and Significance of Economic Science, one of the best-written prose pieces in economics. That book contains three main thoughts. First is Robbins’ famous all-encompassing definition of economics that is still used to define the subject today: “Economics is the science which studies human behavior as a relationship between given ends and scarce means which have alternative uses.”…

●      Who coined the phrase “the dismal science”? The Secret History of the Dismal Science: Economics, Religion, and Race in the 19th Century, by David M. Levy and Sandra J. Peart. Econlib, January 22, 2001.

●      Everyone knows that economics is the dismal science. And almost everyone knows that it was given this description by Thomas Carlyle, who was inspired to coin the phrase by T. R. Malthus’s gloomy prediction that population would always grow faster than food, dooming mankind to unending poverty and hardship.

●      While this story is well-known, it is also wrong, so wrong that it is hard to imagine a story that is farther from the truth. At the most trivial level, Carlyle’s target was not Malthus, but economists such as John Stuart Mill, who argued that it was institutions, not race, that explained why some nations were rich and others poor….

●      … I have been a believer in the repeal of the estate tax for a long time. I wrote a Fortune column on that probably seven or eight years ago. I favor repeal for two reasons. One is just simple economic efficiency. I’m a believer that we should try to move towards a consumption tax and the estate tax which is a tax on capital is fundamentally inconsistent with that. So from the standpoint of efficiency it’s a bad thing….
