We told you so - the two graph version
The Market Monetarist "textbook" will tell you two things: 1) The Friedman yield dictum: Credible monetary easing will push up bond yields as the market price in higher NGDP growth and higher inflation 2) The Sumner Critique: The fiscal multiplier is zero when the central bank in some way targets aggregate demand (inflation targeting, price level targeting NGDP targeting etc.) Here are two graphs that will tell you that we are right. We start 10-year Japanese bond yields. Look at the spike in yields since Bank of Japan governor Kuroda announced his new measures to achieve the BoJ's new 2% inflation target. This is exactly what Market Monetarists have been saying all along - a credible easing of monetary policy will push up NGDP growth expectations and hence push up bond yields. And if you are getting nervous about either the rise in yields "killing the recovery" or threathening debt sustainability in Japan let me just say that one never should reason for a (one!) price change. The increase in yields exactly reflect the expectation of a recovery rather than the other way around. Regarding debt sustainability remember that the rise in yields reflects that monetary easing is increasing NGDP. Hence, debt ratios in Japan will likely decrease rather than increase even if yields are rising. On to the next graph. The Keynesian fiscalists have been screaming about the risks of the fiscal cliff sending the US economy back into recession. On the other hand than the Market Monetarist position has been clear - monetary policy dominates fiscal policy if the Federal Reserve in anyway targets aggregate demand. The Bernanke-Evans rule is doing exactly that. That is why Market Monetarists like myself has been fairly upbeat about the outlook for the US economy since September when the BE rule was announced. US macroeconomic data now seem to confirm the MM position. Take a look at US retail sales. I find it very hard to spot any negative effect of the fiscal cliff, but it is pretty clear that the Bernanke-Evans rule has boosted retail sales in the US. Since the begining to the crisis Market Monetarists have been arguing that monetary policy is highly potent even if interest rates are close to zero. I think the evidence now is very clear and it shows that we have been right. I wonder whether the ECB will start to listen soon... Update: David Beckworth tells essentially the same story as me on the Market Monetarist bias of US macrodata.
