摘要：Many variables in governance are measured with uncertainty. This paper addresses this problem, showing that interval
variables are a suitable way to handle it, providing an application in corporate governance. We build two constructs,
one for Investor protection and the other for Constraints on shareholders based on the original dataset by La Porta et
al. (1998) and we find that for very low levels of investor protection, constraints are a suitable way to provide some
form of safeguard. We also provide evidence for the theoretical claim that investor protection and constraints on
shareholders work as substitutes under specific circumstances.
