But such quibbles are for another time. Here I want to join the market monetarists’ happy dance, and point out several moral benefits of NGDP targeting.
The most plain moral benefit of NGDP targeting is that it is activist. Relative to the status quo, it demands a serious effort to combat the miseries of depression. This is a big improvement over our current strategy, which is to shrug off and rationalize mass deprivation and idleness.
A second moral benefit is that under (successful) NGDP targeting, any depressions that occur will be inflationary depressions. Ideally, we’ll find that once we stabilize the path of NGDP, the business cycle is conquered and there will be no more depressions ever again. But that probably won’t happen. If depressions occur even while the NGDP path is stabilized, then they will reflect some failure of supply or technology. Our aggregate investment choices will have proved misguided, or we will have encountered insuperable obstacles to carrying wealth forward in time. It is creditors, not debtors, whom we must hold accountable for patterns of aggregate investment. There always have been and always will be foolish or predatory borrowers willing to accept loans that they will not repay. We rely upon discriminating creditors to ensure that funds and resources will be placed in hands that will use them well. Creditors allocate capital by selecting the worthy from innumerable unworthy petitioners. An economic downturn reflects a failure of selection by creditors as a group. It is essential, if we want the high-quality real investment in good times, that creditors bear losses when they allocate funds poorly. When creditors in aggregate have misjudged, we must have some means of imposing losses without the logistical hell of endless bankruptcies. Our least disruptive means of doing so is via inflation.
