...there really is no problem with either investment or consumption. Investment in equipment and software has pretty much risen back to its pre-recession level as a share of GDP. This is actually quite impressive, since there is a huge amount of excess capacity in most sectors of the economy.
Consumption is actually high, not low. The saving rate is hovering near 5.0 percent. This is well-below its post-war average of 8.0 percent, before the wealth created by the stock and housing bubbles sparked a consumption boom.
So, if neither investment nor consumption is the problem, then why isn't the economy bouncing back?...The problem is that the country has a large trade deficit. It is close to 4.0 percent of GDP now, and would likely be in the 5-6 percent range if we were back at full employment. (Higher GDP increases imports, which would increase the size of the deficit.) This creates a huge shortfall in demand.
This shortfall was filled during the housing bubble years by a consumption boom and boom in residential construction and some categories of non-residential construction. With the loss of housing bubble wealth, there is no reason to expect consumption to return to its bubble levels. Nor would this be desirable, since it would mean that families are not saving adequately for retirement even as the nation's elite (e.g. the Washington Post, Peter Peterson, etc.) are planning to cut back their Social Security and Medicare.
The only way to get close to full employment in the short-term is through much higher levels of deficit spending. In the longer term we will have to lower the value of the dollar to get the trade deficit closer to balanced.
It really is that simple. The problem is not regulation, taxes, or uncertainty, the problem was that the stimulus was not big enough or long enough. [link]
