Durable Goods Orders and Personal Income and Consumption Reports
Durable goods orders rose 1.9 percent in November, reversing October’s decline of 8.2 percent. However, if transportation is excluded, total durable goods orders fell 1.1 percent. Analysts often exclude transportation to discern the underlying trend in orders. Aircraft, which are part of transportation, are very expensive. If large numbers are ordered, as sometimes happens, the industry can dominate the series. For example, the October number was big and negative, primarily because of hefty aircraft orders in September. The figure below illustrates aircraft’s effect on total durables.
It shows durable goods excluding transportation orders (the dark blue line) as a smoothed version of total durable goods orders. The red line represents transportation orders alone.
Personal Income and Consumption
Personal income, which rose 0.3 percent in November, and consumption, which increased 0.5 percent, are used as inputs in constructing the GDP series.
Over the past five years, personal income as a fraction of GDP has fallen fairly steadily from a high of nearly 87 percent to slightly over 82 percent.
This decline is consistent with observed increases in corporate profits as a share of GDP. Although personal income accounts for a huge fraction of GDP, the quarterly growth rates for personal income and the GDP series behave quite differently.
The personal income series seems more volatile than the GDP series. The chart above suggests the need for caution when using monthly personal income data to estimate quarterly GDP growth.
