Low oil prices are good for 42 states ? and bad for the other eight - Vox

Taking into account the income losses for US oil companies, the net gain in US income will amount to $920 per year for each household. The average propensity to consume is around 90 percent, so the average US household could spend around an additional $825 per year.

Because low-income households spend a greater percentage of their income on energy consumption, and are less likely to own stocks in oil companies, such households will see larger gains and spend more. High-income households will spend less. The overall effect should amount to a one-time increase in US GDP of about 0.7-1.0 percent.
