Unlikely journey towards the PhD

Twenty-five years ago, I started the most unlikely of journeys towards a PhD. My path was rather random and improbable: I was born on the streets of a third-world country to peasants; raised in poverty in Toronto; arrested twice and spent a brief time in prison as a teenager. Higher education was the last thing on my mind when I was expelled from high school. Nevertheless, I eventually managed to earn the highest academic degree -- and under a Nobel laureate supervisor. I am not supposed to be a holder of a doctorate. The PhD is, in many ways, a luxury for the well-off. The median time to acquire a PhD in economics at North American universities is about 5.5 years and with a 40 percent incompletion rate. (Median time from completion of bachelors to PhD is about 8 years, and median age at graduation is 31.) Years of forgone/reduced income and career progression is a steep price for a person trying to escape penury – especially if academia is not the goal. Moreover, insomuch as there is a thing as the opposite of a “tiger family”, that would be mine. We were part of the Cantonese immigrant underclass in…

Losing life’s keepsakes

All my life’s meaningful physical possessions – including my high school diploma -- were contained in a shoebox when I was a young adult. Yet, I threw them all away in my early 20s in a feeling of anger and worthlessness. Growing up I had lived in the attic of my parents’ house. It was a threadbare room with just a mattress, an unusable desk and some steel shelves. I stored my clothes in a few cardboard boxes. I had little in the way of physical possessions. The few that I owned, I had accumulated in a shoebox. They included old gifts and cards from my first girlfriend, a signature from Doug Gilmour (the captain of the Toronto Maple Leafs from the 1990s), my high school diploma, and other keepsakes. I moved out to live on my own in my first year of university as a result of my parents’ house having been foreclosed. My family would eventually regain possession of our home. But as I was no longer living there, I had given permission to them to rent out my room to help with expenses. Several years later I moved back in with my family and took over a…

Paul Krugman

Paul Krugman was my PhD advisor when I was a graduate student at Princeton. I first got to know him (in person) when he taught me the PhD course on international trade. I had many lively conversations with him in class, which inspired me to seek him out as my thesis supervisor. He accepted my request. However, given his status as a columnist for the New York Times and public intellectual, he was scarce on time. People often ask me what it was like having him as an advisor. Although he has a reputation in the profession as someone that can be abrasive and confrontational (especially with people with whom he disagrees), he was always nice to me. It was a routine when we met at his office for him to rifle through the many books sent to him for his critique and comments, and he would pass many of them on to me -- including copies of his own books. As a mind, he was amazingly brilliant and able to offer insights and solutions to problems in a matter of seconds, when I had struggled for days or weeks on them. Regardless of anyone’s opinions about his politics, the…

Daily Princetonian: The graduate student’s long march

Students of English literature might be acquainted with Alan Sillitoe's classic novel, "The Loneliness of the Long Distance Runner."  In that story, the protagonist, Smith, gains relief from his chaotic schedule in a well-heeled boarding school and time to muse about life in his daily runs.  As a runner myself — having competed in track and field, cross-country and marathons — I empathize with Smith. One of the simple pleasures of long-distance running is the seclusion that Sillitoe notes.  The solitude of running provides an opportunity to appreciate, inter alia, the beauty of the sun setting over rolling hills while hearing the sound of leaves crunching under one's feet.  However, sometimes the solitude is simply lonesome. This is why I sometimes think that Sillitoe was in fact writing about the doctoral adventure.  The Ph.D. is a very lonely pursuit, and it goes without saying that it is a long race, metaphorically speaking.  (The median time from matriculation to receiving a Ph.D. is 6.0 years.)  And the isolation of the Princeton graduate experience has given me an epiphany about life: It really is stranger than fiction. Though I don't run on the beach, I often imagine leaving tracks in the sand…
