By Sonali Das and Philippe Wingender Recessions wreak havoc and the damage is often long-lived. Businesses shut down, investment spending is cut, and people out of work can lose skills and motivation as the months stretch on. But the recession brought on by the COVID-19 pandemic is no ordinary recession. Compared to previous global crises, […]
By John Bluedorn The COVID-19 pandemic’s destruction of jobs was sure and swift. The lasting effects of the crisis on workers could be just as painful and unequal. Youth and lower-skilled workers took some of the hardest hits on average. Women, especially in emerging market and developing economies, also suffered. Many of these workers face […]
The output gap is a key concept in macro. Students in my courses have asked about the characteristics of some of the proxies. Here are some representative examples. Figure 1: Cyclical component from Hodrick-Prescott filter (blue), from Baxter-King band pass filter (red), Hamilton filter (green), and output gap from CBO (gray), all in logs, estimated […]
The goods production side of the economy continues to recover, consumption jumps, while other indicators faltered. Some key indicators followed by the NBER Business Cycle Dating Committee.

I talked through some issues regarding the competing recovery plans in this Wisconsin Public Radio interview. Here are some graphs to buttress my point that the Senate Republican plan is underpowered. First, where is the economy? Facing a big output gap, even after all that previous fiscal stimulus. Figure 1: GDP (black), CBO projection (red), and […]
Title of an article a few days ago: The problem is the economy isn’t crashing and burning — just the opposite. The pandemic lockdowns flattened the economy earlier this year, and there’s lots of heavy lifting to do to get all the jobs back. But they are coming back, and Trump will be bequeathing to […]
And the recovery is well under way.
Real gross domestic product (GDP) increased at an annual rate of 33.1 percent in the third quarter of 2020 (table 1), according to the “advance” estimate released by the Bureau of Economic Analysis. In the second quarter, real GDP decreased 31.4 percent.
This is from a news release from the U.S. Department of Commerce’s Bureau of Economic Analysis, October 29, 2020.
A 33.1 percent annual rate of increase means that that would be the rate if the rate of increase of the summer quarter continued for 3 more quarters. Of course, that won’t happen. To put it in perspective, a 33.1 percent annual increase implies that real GDP in the summer quarter increased by 7.4 percent. That’s a record increase for a quarter.
Of course it comes after the huge decline of 31.4 percent (annual) in the spring quarter, which happened due to Covid-19 and the lockdowns.
That doesn’t make it even. If a number falls by 31.4 percent, then to get back to where we where, we need an increase of 45.8 percent.
To help with the math on the second point a little, here’s how I put it after a tutorial during which I watched myself on video in prepping for my first distance-learning class way back in 2002: “The camera loses 1/4 of my energy; therefore I need to increase my energy by 1/3.”
Here’s the math on both if you’re interested and, for that matter, even if you aren’t interested.
Let x be the quarterly rate of growth.
Then (1+x)^4 = 1.331.
4 ln(1+x) = ln(1.331) = 0.2859
ln(1+x) – 0.2859/4 = 0.07148
1+x = e(0.07148) = 1.074
Therefore x = 0.074. Growth rate = 7.4 percent.
On the second one.
If a number falls by 31.4 percent, it falls to 68.6 percent of what it was.
To get from 68.6 percent to 100 percent, it must rise by 1/0.686 = 45.8 percent.
Just in time for the module on fiscal policy in my macro policy course, multipliers in a time of Covid-19. From a CBO working paper by Selsiki, Betz, Chen, Demirel, Lee, and Nelson, “Key Methods That CBO Used to Estimate the Effects of Pandemic-Related Legislation on Output”. Table 2 reports the ranges for a period […]
Given apparent gridlock in Washington – that is the gap between the administration and Senate Republicans on phase 4 recovery package – Wall Street economists and academics see the recovery somewhat differently. From the Initiative on Global Markets/FiveThirtyEight Covid panel round 10 survey (released October 12). Figure 1: GDP actual (black bold), WSJ October survey […]
Deceleration continues, according to some key indicators noted by the NBER’s Business Cycle Dating Committee (BCDC).
