Most other economic indicators also reveal a deterioration in the economy, although the rate of decline has slowed, as of course had to happen at some point. The media tend to focus on month to month percentage changes in the indicators, but a more illuminating comparison is with the same month in the last pre-depression year, which was 2007. If some indicator, like employment or housing starts, was 100 in May 2007, 70 in May 2009, and 80 in June 2009, the May-June change is strongly positive at plus 14 percent; but the indicator is still 20 percent below its pre-depression level. Similarly, the DJIA has risen by about 5 percent since the close on January 20, but is 42 percent below its 2007 peak of 14,200. The unemployment rate was 5.7 percent last June (before a mild recession became a depression), the underemployment rate was 10.3 percent, and the aggregate number of hours worked per week was 107.
The Gross Domestic Product (the market value of all goods and services produced in the economy) is unchanged since the end of 2007; since the inflation rate in 2008 was 3.8 percent, and average annual real growth in the economy is about 3 percent, the economy is operating at almost 7 percent below trend. On the one hand, this exaggerates the real decline in potential economic output, because unemployment and underemployment shift some resources from market to nonmarket output; for example, people eat at home more, substituting home production of meals, which is not included in estimates of GDP, for the purchase of restaurant meals, which is. On the other hand, and of vastly greater significance from the standpoint of utility (welfare, happiness, preference satisfaction), a severe economic downturn produces great anxiety on the part of all who lose their jobs, suffer a loss of income, or fear such losses.
Another statistic of significance is the increase in the personal savings rate: from 4.6 percent to 6.9 percent since January of this year--but in 2007 it was less than 1 percent. The significance of these increases lies in the fact that money saved is diverted from money spent to buy goods and services, and the decrease in spending results in reduced production and therefore employment, and reduced employment leads to a further reduction in spending. Low personal savings rates in the early 2000s, coupled with the housing and stock market booms, meant that people's savings were heavily concentrated in housing and stock. When the market value of those assets plummeted, people found themselves with inadequate assets relative to debt, and curtailed spending. The ensuing recession became a depression when the financial crisis of last September froze credit, resulting in further reductions in spending. The banks were saved, but credit remains extremely tight.
There are some indications of incipient recovery, including upticks in manufacturing and sales of durable products and housing starts. But as long as unemployment (and underemployment) is rising and housing prices (a major store of value) and personal consumption expenditures are depressed, the economic prospects are uncertain. There have been too many false dawns and overoptimistic predictions, including by government officials. An example is the emphasis on unemployment as a "lagging indicator" of depressed economic conditions. It is true that unemployment often continues increasing after an economic recovery begins. The standard explanation is that firms prefer not to incur the cost of hiring or rehiring workers until they are sure that demand for goods and services is increasing. An alternative explanation is tacit collusion: firms may hesitate to expand output as demand rises, hoping their competitors will follow suit, since the more slowly supply rises in response to rising demand, the faster prices and profits will increase. But it is only after a depression is over that one can recognize an increase in unemployment as a lagging indicator. It would have been ridiculous to observe the steep decline in employment in 1930 and be reassured that, since unemployment is a lagging indicator, the depression was over. It had just begun.
