President-elect Trump is right: the economic recovery post-Crisis has been tepid. An academic paper I found in the process of writing our recently-published report to IOI members analyzing the investing implications of the incoming administration suggests that the amount of underperformance is about 12%. In other words, the economy would be more than a tenth larger if it were growing according to the historical trend.
This underperformance is very visible in one of the charts in the full report:
We believe that the notable underperformance since the Great Recession (marked by “Region D” in the figure above) relates to a period of deleveraging among American households.
However, the academic paper, written by a PhD candidate at New York University, Callum Jones, finds that an even larger effect is due to simple demographics. According to Jones’s model, roughly 50% of the output gap can be attributed to retiring Baby Boomers’ saving, spending, and working habits, and only roughly 20% to “real” effects, such as deleveraging.
The paper is wonkish (what academic paper is not), but it does raise an interesting point. Namely, that slowing GDP is a structural, rather than policy issue. While we think deleveraging has a greater impact (see the full IOI report for the reasons why), we realize that demographic effects are extremely powerful, so are likely adding to the malaise.
