This will cause major oil exporters to run either smaller budget surpluses or bigger budget deficits. In the aggregate, the swing from oil producers to consumers is quite large. For example, a $ per barrel decline in global oil prices results in an income transfer of about $ billion per year from producers to consumers.2 This understates the total effect because it does not include any knock-on reductions in other energy prices – such as for natural gas – that, outside the U.S., often are linked to oil prices. Obviously, if the oil price declines were to both intensify and persist, this would have negative implications for oil and gas investment in the U.S. At a minimum, as cash flows fall, some producers will cut back on their drilling activity rather than plug the shortfall with outside financing. Nevertheless, there are several reasons why I don’t think this risk should be overstated, especially if oil prices stabilize around current levels. First, even after the large gains in recent years, oil and gas investment remains a small fraction of GDP. Second, domestic natural gas investment should be relatively unaffected because U.S. natural gas prices are largely insensitive to global energy price developments. This reflects the high costs associated with exporting natural gas and the fact that most of our oil production is used for transportation purposes. Thus, the ability to substitute lower cost natural gas for oil is limited. Third, extraction costs vary appreciably across the different major oil fields.
In addition, household net worth has recovered sharply, boosted primarily by higher financial asset valuations, but also by some recovery in home prices. Third, the fiscal restraint that has held back growth in recent years has ended, with the federal budget deficit now at a level consistent with a stable to slowly declining federal debtto-GDP ratio. In the aggregate, state and local governments have also ended their retrenchment. One important piece of evidence in this regard is the fact that state and local  1  See, for example, the latest Blue Chip consensus survey (volume 39, no. 11, November 10, 2014). The median real GDP forecast for 2015 (fourth quarter over fourth quarter) is 2.9 percent.

Now that these headwinds have subsided, buoyant financial market conditions spurred, in part, by a very accommodative monetary policy should do more to support economic activity. In particular, compared to historical patterns, the current household net worth-to-income ratio is high relative to the personal saving rate. This suggests some scope for a decline in the household saving rate. If this were to occur, consumption growth would outstrip income growth. Similarly, financial market conditions are conducive to sustained gains in business fixed investment. Equity prices are high, borrowing costs are low, cash flows are strong and corporate balance sheets are healthy.
