JIM LINDGREN & ROSS STOLZENBERG: Retirement and Death in Office of U.S. Supreme Court Justices. “Computing robust standard errors with adjustments for clustering by justice, we find that the odds that a justice will retire (or resign or take senior status) in the first two years of the term of a president of the same political party as the president who first appointed him to the Court are about 2.6 times the odds of retiring under a president of the opposing party in the last two years of his presidential term.”
