This microsite contains teaching materials for most of my courses: revised chapters of my textbook (last edition, 2013), PowerPoint presentations, cases and exercises; in Spanish (mostly) and/or English. Cases and exercises are at different degrees of completion. Some include an analysis (but not a solution), while others only propose additional questions. Some of these analyses are publicly available but others are reserved for teachers, for use in exams. Registered teachers can also add their own comments in a blog-like manner. Interested teachers may contact me at email@example.com.
