The Welch book has been used at many top-tier and not-so-top-tier finance departments, for example, at Harvard, Yale, Columbia, Brown, Berkeley, UCLA, and many others. It has also been used by many mid-tier and non-ranked universities, at undergraduate and graduate levels. In direct competition, students have always preferred this textbook to its peer alternatives.
