The asymmetric response of the economy to tax changes before and after 1980

This paper explores the asymmetry in the response of GDP to tax shocks before and after 1980 as first noted in Romer and Romer (2010). I find that there are two main reasons why output responds more strongly to tax shocks before 1980 than after. First, a greater sensitivity of the effect of tax shocks on output to the state of the economy before 1980 explains about half of the difference between periods. Second, before 1980 the effect of tax shocks on households is indirect and lowers total personal income and nondurable goods consumption. After 1980 tax shocks affect personal tax payments directly, causing disposable income and savings to change. This finding affirms Romer and Romer’s hypothesis that households are more likely to consumption smooth. However, I find that households after 1980 consumption smooth in response to a change in their direct tax burden not, as Romer and Romer posit, because they have greater access to financial services.
