		| This paper updates the empirical evidence on the role of federal regulation and taxes in the well-known productivity slowdown of the 1970s, based on revised and extended data on federal regulation and marginal tax rates through 2016 in the U.S.  The analysis uses a time-series model derived from endogenous growth theory with regulation and taxes as policy variables.  Co-movement among the policy variables and productivity growth—during both the slowdown and the subsequent recovery—suggests regulation may have played a role.  Tax effects are small and statistically insignificant.  The updated results also suggest a new productivity slowdown is underway, since the early-2000s, and that regulation may once again have something to do with it. |
