One possible way to resolve certain types of conflicts of interest is to put a public official's assets under fiduciary management and curtail the owner's discretion over them.

In 2019-2021, a large-scale project to study corruption in Russian public procurement was conducted. One of its main results was a detailed catalog of 100 undue techniques used by unscrupulous customers to design corrupt tenders.
