Martin Feldstein on the U.S. economy in 2014 and the risks of the U.S. Federal Reserve tackling the economy on its own with monetary policy, without Congress taking on the task of policies to promote economic growth. Feldstein points out the 3.6% GDP growth estimate for the third quarter 2013 does not look that good considering that half of this is from buildup of inventory. GDP growth is about 2% as net result. With paralysis of Congress and the Executive branch the Fed's policy of huge buildup of long term bonds to reduce short term interest rates to zero and stimulate stock and home prices, he describes as the only game in town. The problem is that the size of the effect of increase in consumer spending from this increase in household wealth is small and not enough to contribute to significant GDP growth. The risks of this approach are that it contributes to destabilizing the economy as investors buy risky securities and bid up prices. He suggests a five year $1 trillion infrastructure development program, including defense, as a stimulus Congress should consider. Not the kind of stimulus that happened after the 2008 crisis. If not enough investment ready projects are available as in 2008 that will contribute to future growth, Congress should take another one year to prepare for this before moving forward. Debt reduction is key, and debt as a percentage of GDP should be reduced and set on a path to go where it was before 2008 to about 40%, deficits to below 2% of GDP. This should be done by slowing growth of Social Security and Medicare, and increasing revenues by limiting subsidies in the tax code that Feldstein as pushed for since 2010....
