Is It a Honeymoon? An Empirical Investigation of the President's First Hundred Days

This paper tests the hypothesis that presidents are more successful in Congress during their first hundred days in office. Analyzing an original dataset composed of the bills on which presidents took official positions, it finds that presidents indeed have higher success rates during the first hundred days of their first year than they do later during their first year or during the first hundred days of noninaugural years. This effect is strongest for presidents who face divided government.
