I urge my graduating IB economic students to read it (or, at least save it and read it sometime later). This is just a short quote to whet your appetite:
While Adam Smith has recently been much quoted, even if not much read, there has been a huge revival, even more recently, of John Maynard Keynes. Certainly, the cumulative downturn that we are observing right now, which is edging us closer to a depression, has clear Keynesian features; the reduced incomes of one group of persons has led to reduced purchases by them, in turn causing a further reduction in the income of others.The article is found here.
However, Keynes can be our savior only to a very partial extent, and there is a need to look beyond him in understanding the present crisis. One economist whose current relevance has been far less recognized is Keynes's rival Arthur Cecil Pigou, who, like Keynes, was also in Cambridge, indeed also in Kings College, in Keynes's time. Pigou was much more concerned than Keynes with economic psychology and the ways it could influence business cycles and sharpen and harden an economic recession that could take us toward a depression (as indeed we are seeing now). Pigou attributed economic fluctuations partly to "psychological causes" consisting of variations in the tone of mind of persons whose action controls industry, emerging in errors of undue optimism or undue pessimism in their business forecasts. It is hard to ignore the fact that today, in addition to the Keynesian effects of mutually reinforced decline, we are strongly in the presence of "errors of...undue pessimism."
