I find the pre-doc discourse very depressing because I did a great master's (and ranked highly in my class), a great pre-doc, and didn't place in a top-5 program. I think people underestime the cost that comes from uncertainty, too.

I keep seeing this, and it's such a bad point. Shouldn't we let the people being invaded decide whether or not they want to resist, and offer our support if they do? Seems crazy paternalistic to me to say "oh, no, these guns will just prolong your suffering, just roll over".

It's shocking that a Prof of biostatistics - a fellow academic - would think that a prof of microecon would write a paper using DiD without implementing a D (or that a paper could make it through a dozen seminars + peer-review without somebody pointing out that a D is missing).

"Who is considered" does a lot of work here. If we're going by popular opinion, I think Einstein wins. No other person's name is as synonymous with genius. I'm not sure what other metric you would use for "who is considered" - are there experts on smart-ness?

My particular case was odd. I was told after finishing my master's at LSE that they would have funded my admission to the PhD (autom. based on grades), but they thought my chances of admission to a T5 would be high after the pre-doc. But nothing is guaranteed!

I am generally pro-predoc. I think the value of getting a signal of whether you like the day-to-day of research, w/o committing to a PhD, is high. There are costs to extending the time-to-market, sure, but there are also savings realized for those who learn what they want early.

I did/am doing a master's and a pre-doc; I think this is reductive. My pre-doc is teaching me far, far more about doing research than my MSc did. If you're 100% sure about wanting a PhD, a great pre-doc (w/ great prof) is a better path imo. If you're unsure, do a funded MSc first

Isn't it harder, though? The statistics on PhD origins of faculty in the USA are quite striking; going to a program outside the top 20 and wanting to be an academic economist seems like it would pretty much require topping your PhD cohort (and I'm just not that confident).

My sense is also that pre-docs democratize access to good programs, but that's an empirical question. Certainly, doing my undergrad at a lesser-known Canadian school, I would have had essentially zero opportunity to get RA experience w/o it.

Was thinking about this earlier this week. An LLM (that hallucinates a lot less, especially re basic math and stats) + a designed curriculum could completely change the traditional classroom.

Obv. as a y1 grad student, it's hard to know what my objective function should be, but so far I've found the best way to learn material = study hard, and that tends also to prod. reasonably good grades. Should goal 1 in y1 not be to maximize understanding of core material?
2. College grades matter for getting into econ/finance PhD. Some PhD students actually work hard in 1st year and try to ace their classes, not realizing that this basically has 0 direct effect on whether you'll find a job after PhD, it's all about writing papers

If your house is rented/flipped it is capital, but if you live in it, it is not capital? Seems to me that in both cases, the house is producing housing services, and whether the owner consumes those services or not, it is still a means of production.

If cost is a factor, Canadian MAs are dirt cheap relative to their American/UK counterparts (UBC, U of T). For more of a policy focus, PSE APP is a good option (I've heard). Oxford, LSE, UCL are good options, all much more expensive than Canada/France.

Leaving aside editorializing by presenter -
1) DICE stuff is very out of date. DICE w/ curr. dmg. models pushes SCC up around $60 (wouldn't call that close to 0). Can justify a wide class of policies at this number, incl. positive carbon tax. Yes, implies some warming optimal.
