US GDP fell for the second straight quarter according to statistics released this week by the Bureau of Economic Analysis. This means that by one common definition we’re now in a recession, which has ignited a debate about whether “two consecutive quarters of negative GDP growth” is the best definition (as opposed to ‘when the NBER says there’s one’, like I generally teach and Jeremy argued for here, or something else).
Naturally this debate has political overtones, since the party in power would be blamed for a recession, so we’ve seen the White House CEA argue that we’re not in a recession, many on the other side argue that we are, and plentiful hypocrisy from people who should know better.
But in political terms, the fight over the binary “are we in a recession” call won’t be the big economic factor in November’s elections- that will be inflation and GDP, especially 3rd quarter GDP. One of the oldest and best predictors of US elections is the Fair Model, which uses inflation and the number of recent “strong growth quarters”. Fair’s update following the recent Q2 GDP announcement states:
the predicted vote share for the Democrats is 46.70, which compares to 48.99 in October. The smaller predicted vote share for the Democrats is due to two fewer strong growth quarters and slightly higher inflation
By Election Day we’ll have 3 more months of economic data making it clear whether inflation is getting under control and whether economic activity is picking back up or continuing to decline. Monthly data releases on inflation and unemployment will be closely watched, but the most discussed release will likely be third quarter GDP. It will summarize 3 months instead of just one, it will be of huge relevance to the debate over how severe the recession is or whether we’re even in one, and it will likely be released less than two weeks before election day. The NBER almost certainly won’t weigh in by then; they tend to take over a year to date recessions, not adjudicate debates in real time.
So when BEA does release their Q3 GDP estimate in late October, what will it say? Markets currently estimate at least a 75% chance it will be positive (they had estimated a 36% chance of positive Q2 GDP just before the latest announcement). That sounds high to me, the yield curve is still inverted and I bet investment will continue to drag, but forecasting exact GDP numbers is hard. Its a much easier bet that whatever the number turns out to be will loom large in political debates just before the elections. Perhaps we’ll get the Q3 GDP growth number that would make for the most chaotic debate: 0.0%.
