Nine stimulus studies

We've talked about several of these on here before, but Dylan Matthews reviews nine stimulus studies - six of which say it had a positive effect, one which says it had a modest effect, and two that said it didn't work.

I've got a few broad thoughts on these. I don't like inter-state studies. I doubt we can really say anything about any one recession, unfortunately - I think it's better to just look at the impact of fiscal policy in a recession in general. Papers that don't deal with endogeneity aren't really worth your time. Papers that do deal with endogeneity often have trouble focusing on impacts during recessions. And it's been six or seven years so I have to take another time series class before I express an opinion on VAR studies.


  1. Nine is a natural number. The circles of hell in Dante's most famous work (though not my favorite of his) is nine. Nine is also the most common number of assorted Greek muses. That is all I have to say about nine this morning.

  2. " three conclude the stimulus had a significant positive effect, and two conclude it did not have much of an effect at all."

    Significant meaning "important and meaningful" or non-random?
