CONTEMPLATING MACROECONOMICS.

Lynne Kiesling has a useful summary of the macroeconomics of stimulus failure, with numerous links.  The Say's Law she invokes is the same accounting identity I refer to as the Say Aggregation Principle, which E. J. Mishan demonstrated in 1963 is the same identity students of general equilibrium learn as Walras's Law (the aggregate value of excess demands is zero, in and out of equilbrium; that trailing prepositional phrase is not always fully appreciated by novice economists).
