Some Forecasts

It’s been interesting to me to see how various economic groups assess the outlook. Here are a select few:

While rapid growth is projected for the end of the year, it’s of interest to note that output will still be below the pre-Covid19 trajectory.

It must be an unenviable task to forecast output in these times. Thinking about it a bit, on top of the usual challenges, these forecasts have to be conditioned on big question marks (so known unknowns as well and unknown unknowns).

  1. Scientific unknowns about degree of contagiousness, whether there’s seasonality, the ease of reinfection
  2. Political unknowns such as commitment to developing an infrastructure to test, track the epidemic, so that the economy can be restarted without large increments to fatalities.
  3. Unknowns regarding how the health infrastructure has been degraded by the scattershot administrative response, thereby constraining the readiness for restart
  4. Unknowns regarding administrative capacity of a Federal government that has many policy level positions still vacant.
