As for why higher teacher salaries lead to improved academic outcomes, the researchers speculate that increased pay attracts higher-quality candidates, boosts retention, and heightens morale and enthusiasm for the job.
while that still means that a general pay raise wouldn't be reflected one to one in test scores, it'd still improve education overall, and likely turn bad or mediocre / unmotivated teachers into better ones - and not "just be paying bad teachers more":

Prior research has shown that increased teacher salaries prompt higher quality students to seek careers in education. Additional pay also lowers teacher turnover, keeping talented, experienced teachers in their jobs and resulting in more educator continuity for students, which builds trust between teacher and pupil.
