This study provides a first assessment of awareness of, attitudes toward, perceived norms regarding, and adoption of open science practices within a broadly representative sample of active economics researchers. We observe a steep increase in adoption over the last decade, with an accelerating trend: as of 2017, 93 percent of economists had used at least one such practice—including posting data, sharing study materials, and study pre-registration—rising from 33 percent a decade earlier. We document extensive variation in adoption across economics subfields. Notably, most economists appear to underestimate the trend toward research transparency in the discipline.
