The 2018-19 shutdown was certainly not bad for investors. The S&P gained 10.3 percent during the last shutdown. During the 16-day shutdown in 2013, the S&P 500 experienced a gain of about 3.1 percent. If anything, the market seems to like shutdowns.

The effects on the economy, in any case, are likely to be so slight as to not matter. Certainly, lawmakers considering whether to vote for legislation or shut down the government should not worry about how this will impact jobs, wages, or growth. We will be just fine economically even if the government shuts down until Trump is sworn in to his second term.
