While depression economics has many strange features, the most important one to remember is this: with slack in the economy, it’s possible to have an economic free lunch. If our economy were running at capacity, new government spending, for example, would tend to create inflation because the capacity (workers, raw materials, and equipment) would have to be bid away from someone else, thereby raising prices. But during a depression that doesn’t happen. Instead, new spending brings idle capacity into production. To put that another way, the single-most-important underpinning of a functioning economy is to ensure that there is sufficient aggregate demand. Federal K9 Grants
The third policy option is known as nominal gross domestic product targeting, the major proponent of which is the economist Scott Sumner. The idea is all about self-fulfilling expectations. Recall that the central bank owns the printing press, so it can create arbitrary quantities of dollars. By making a pre-commitment to keep the economy on a particular spending trajectory, self-fulfilling collapses in spending would not happen. Something similar to this policy seems to have kept Australia and Israel out of the Great Recession. But in order to sustain such a policy, the Fed might have to intervene in the economy quite frequently, and then the distributional consequences could be serious. Quantitative easing, for example, helps push up asset prices (the stock market has regained all the ground lost since 2009 and then some), which disproportionately benefits the wealthy.
