We have released the latest version of the Institutional Grammar (IG) 2.0 Codebook.

The IG 2.0 is a revised version of the original Grammar of Institutions by Crawford and Ostrom (1995; 2005) that aims at coding so-called institutional statements (e.g., norms, rules) found in policy documents. IG 2.0 allows the coding on multiple levels of expressiveness that serve different analytical purposes and furthermore facilitates the coding of regulative and constitutive statements. More details can be found here.

Specific changes in this release of the Codebook include:

• Revision of selected coding examples
• Updated study design guidance in appendix

The Codebook is available under https://arxiv.org/abs/2008.08937
