We have heard much about the puzzle that US economic performance under President Joe Biden has been much stronger than voters perceive it to be. But the current episode is just one instance of a bigger historical puzzle: the US economy has since World War II consistently done better under...

"Since World War II, Democrats have seen
job creationaverage 1.7 % per year when in office, versus 1.0 % under the GOP. US GDP has averaged a rate of growth of 4.23 percent per annum during Democratic administrations, versus 2.36 per cent under Republicans, a remarkable difference of 1.87 percentage points. This is postwar data, covering 19 presidential terms—from Truman through Biden. If one goes back further, to the Great Depression, to include Herbert Hoover and Franklin Roosevelt, the difference in growth rates is even larger.
The results are similar regardless whether one assigns responsibility for the first quarter of a president’s term to him or to his predecessor. Relatedly, the average Democratic presidential term has been in recession for 1 of its 16 quarters, whereas the average for the Republican terms has been 5 quarters, a startlingly big difference."
"The
last five recessions all started while a Republican was in the White House (Reagan. G.H.W. Bush, G.W. Bush twice, and Trump). Readers can check out the
chronology for themselves. The odds of getting that outcome by chance, if the true probability of a recession starting during a Democrat’s presidency were equal to that during a Republican’s presidency, would be (1/2)(1/2)(1/2)(1/2)(1/2), i.e., one out of 32 = 3.1%. Very unlikely. The same as the odds of getting “heads” on five out of five consecutive coin-flips. Such a rejection of equality is said to be “statistically significant at the 95% level of confidence.”
What if we go back further? A remarkable 9 of the last 10 recessions have started when a Republican was president. The odds that this outcome would have occurred just by chance are even more remote: one out of 100. [That is, 10/210 = 0.0098.]"
