Many analysts had anticipated that a dramatic drop in oil prices such as we’ve seen since the summer of 2014 could provide a big stimulus to the economy of a net oil importer like the United States. That doesn’t seem to be what we’ve observed in the data.
There is no question that lower oil prices have been a big windfall for consumers. Americans today are spending $180 B less each year on energy goods and services than we were in July of 2014, which corresponds to about 1% of GDP. A year and a half ago, energy expenses constituted 5.4% of total consumer spending. Today that share is down to 3.7%.
