How sensitive are economic sentiments as measured by the University of Michigan survey, depending upon party affiliation? Apparently, over the period of the Biden administration, it\u2019s higher for Democrat and lean-Democrat.<\/p>\n

In other words, it\u2019s a little harder to link Republican\/lean Republican sentiment to a text-based news index.\u00a0 The constant is statistically significant, whereas the slope coefficients are not significantly different, using the 5% significance level (F-test).<\/p>\n I also show a nonparametric smoother (nearest neighbor, window=0.7):<\/p>\n Figure 2:<\/strong> University of Michigan sentiment by Democrat\/lean-Democrat (blue circles), by Republican\/lean Republican (red circles) vs. Shapiro-Sudhof-Wilson SF Fed news sentiment index, 2017M02-2024M02.

(The slope coefficient for Democrat\/lean-Democrat is statistically significantly different from zero using HAC robust standard errors.)<\/p>\n<\/p><\/div>\n![\"\"](\"https:\/\/econbrowser.com\/wp-content\/uploads\/2024\/03\/umcsent_partisan.png\")
