A couple of factors make my Ph.D. experience unique.
One, I am doing a Ph.D. on something I never practised before in the field — not without considering marketing is actually applied microeconomics or treating communications as a signalling device. After 14 years of working in marketing and communications, diving straight into a Ph.D. in Economics is deemed by many a crazy move. In the first place, it is also a shift from full-time work to full-time studies.
Two, I often find myself in the company of classmates who are mostly way younger than I am. As some classes are shared by masters and doctoral students, the diversity in age and personalities is very pronounced. These heterogeneous classes would have, in some cases, a 20-year gap between the youngest and oldest students in class (I happen to have a 15-year gap with the youngest; so even then, there’s still someone older than me most of the time). This diversity has mostly positive effects that I appreciate; one of which is that young guns and the old ones seem to share complementary roles in understanding issues where the old ones provide some wisdom, the young ones would easily and confidently assemble in mathematically superior arguments. What the older students like me lack in mathematical tools is compensated by real-world experience. Conversely, what the young ones lack in real-world experience is compensated by their strong mathematical dexterity.
