“…Though this review is primarily focused on quantitative cross‐national research, qualitative research, and single‐country research is intentionally under‐examined in this article, it is important to emphasize the cross‐pollination across research modes. Corruption research is highly interdisciplinary (Jancsics, 2014), and case‐study and qualitative work on the subject is both vast and detailed (see Busgnell, 2020; Goh, 2008; Toma, 2015; Zhang, 2020). While a cross‐national measure of corruption cannot capture all of the nuance and depth from the qualitative and case study research, we can at least be more specific in the measures we use, while also grounding our operationalizations, measurements, and mechanisms of corruption in case‐study and qualitative work.…”
