We aim to raise awareness of the benefits of conducting international research rather than just single-country studies (which tend to be dominated by U.S. data). We outline the key challenges in terms of data collection and empirical design and propose various data sources for country-level variables, including formal and informal institutions. We also describe several hands-on approaches that are suitable in a crosscountry setting.

Data Availability: Data are available from sources indicated in the paper.
