How well do unemployment and inflation explain presidential approval ratings?
Core argument: The Michigan Consumer Sentiment Index, inflation, unemployment, and noneconomic factors together provide a relatively complete explanation of the variance in US presidential approval ratings since 1956, with the combined unemployment-and-inflation contribution negative except briefly in 1999.
The combination of MCSI [the Michigan Consumer Sentiment Index], the two economic indicators [inflation and unemployment], and the set of noneconomic factors provides a relatively complete explanation of the variance in Presidential approval ratings since 1956. The separate roles of the sets of explanatory variables are captured by Figure 8. At the top the combined contribution of the unemployment and current inflation indicators, which is always negative except briefly in 1999. The role of the two oil shocks of the 1970s in making unemployment and inflation worse together dominates the blue frame, with additional negative contributions coming from high unemployment in the 2008-09 recession and its aftermath, and from high inflation in 2022-23. Once non-economic effects are taken into account, the advantage of the MCSI over the economic variables disappears, and in fact only unemployment and current inflation are significant. There is a continuous negative orange area after 2000 representing the post-Millenium decline in average approval, together with extra negative orange boxes for the last term of Bush junior, for all of the Trump Presidency, and for Biden’s last two years.
