I do not agree with Hugh Cameron that Say's Law is a "fallacy" of economics but then again he doesn't list the statements so it is difficult to pass judgement as to whether or not we have a genuine fallacy or just a statement that needs minor qualifications. Please remember that a rise in the minimum wage does help some workers---those who keep their jobs! The same can be said of rent control---a leading libertarian who I knew quite well enjoyed a huge NYC apartment (6 rooms) most of his life do to the benefits of rent control. Without such amenities some of the most important writings of that last century might never have been written. Still, in keeping with the spirit of his project I recommend what Ludwig von Mises called the "lump of labor fallacy" be added to the list. At this time of intense debate about immigration reform, this fallacy keeps popping up. The claim is made that in any region (say, Alphaville) there is only so much work that needs to be done. When the immigrants come into to Alphaville they leave less work for the natives to do and that means the immigrants cause unemployment. Based on frequency with which many of hear this idea (I have economics majors in my class sharing this wisdom), I think it might indeed be not only a major fallacy but also one of the most pernicious doctrines in the social sciences. Another and perhaps more interesting question is to link the proposed fallacies to those economists who battled them in their lifetimes. I mentioned von Mises and of course there were many others. I forgot who described economics as a "defensive science," one that disarms those who might make our lives more tragic by ignorance or hubris. Laurence S. Moss
