I am a teacher. That is how I describe myself to anyone who chooses to ask me what I do for a living. I am not a professor (sounds pedantic and pompous), definitely not an academic (how boring is that..) and don’t consider myself anything more than a dilettante on almost every topic that I hold forth on. It is in pursuit of my teaching mission that I have put my regular classes online for most of the last two decades, though technology has made that sharing easier. For those of you who have read my postings before, I usually announce a few weeks ahead of every semester, the classes that I will be teaching at Stern, what each class is about and how you can access it, as I did in January with my Spring 2017 valuation and corporate finance classes. As September 2018 approaches, I was going to skip that ritual, since I will be on sabbatical next year (and if you have no idea what a sabbatical is, more on that later..) but I will be teaching, nevertheless, during the year.
