Generally-speaking, on polls I've seen in the past, Trump is more-highly-regarded than Biden on economic issues among Americans.

I've seen inflation referenced as a factor. Relative to recent decades, the Biden administration saw relatively-high inflation, and the Trump administration slightly below the norm. Inflation is a pretty visible indicator to people -- you see gasoline prices every time you refill the tank -- so a lot of public opinion of how a president performs economically hinges on what inflation is doing while they're in office.

I don't know about any recent shifts in the last few months, but Biden polling poorly on economic issues is more-or-less what I'd expect.

I don't know how quickly that fades. Inflation has fallen off, but prices have already risen. Probably possible to look at past polling data to see how sticky perceptions are after periods of high inflation.

The public prefer a recession to inflation

Did I say the public hate inflation? I meant they really hate inflation. It’s old, but this study by Nobel laureate Bob Shiller examined how much people disliked prices rising and why. Posing detailed questions to respondents in the US, Germany and Brazil, he first found people didn’t really worry about recessions and prized low inflation. In the US, 75 per cent of his survey preferred a world with 9 per cent unemployment (12mn) and 2 per cent inflation to one with high inflation and low unemployment. Germans took the same view, with 72 per cent favouring the recessionary world, while the results in Brazil were closer, but still 54 per cent wanted to avoid high inflation. On deeper probing, Shiller found that people think inflation is something done to them by government or companies (they really believe in greedflation), but if their wages rise, they earned it all by themselves.
