It’s a bit early for me to be giving advice (I’m only on the cusp of non-Assistant status), but I found myself asked for advice the other night by a table full of newly minted PhDs on to their first academic jobs. I also give advice, unasked, to my graduating students.

So, early or not, here’s what I passed on. Mainly of relevance, I suspect, to economists and political scientists.

Learn to say no to new projects. Opportunities will start crossing your desk faster than you expect. It’s tempting to take the first ones, even though they’re likely the worst. There’s a big opportunity cost here: every project you take on now crowds out a potentially better one in a year or two. Have a higher bar for projects with big exit costs. It’s one thing to start a historical data collection project or a new theoretical model. You can always stick it in a file drawer if it goes poorly. But if you commit to a field experiment or a project with an eminent person, you are stuck with it to the bitter end. Make sure they are worth it. Book chapters and reviews are a waste of time. David Romer told us this in my first macroeconomics class, and I have come to agree. Few people read these, especially when they are buried in a $200 book no library buys. Unless you’re invited to do a Handbook chapter or an especially high profile book, it’s almost always better to put your article in a field journal. If it doesn’t merit publication in a decent field journal, probably it’s crowding out something more important to you and the world. Get your dissertation papers or book out. I see so many people too busy starting new projects to finish the old ones. This is the kiss of tenure death. Send menuscipts out soon after the job market, and make revisions your first priority when they come back. Seek out mentorship. Ask your dissertation committee and colleagues in your new department to read your abstracts and introduction, and strategize about framing, titles, and generally how to sell your work to a general audience. This is an art that takes years to learn, and personal advice can make a big difference in where you publish your early work.

A word of caution: almost all professional advice is either “here’s the mistakes I made” or “how to be more like me” in disguise. In this instance, it’s more of the former than latter.

For someone with real experience, you should read Greg Mankiw’s advice. I agree with all, except for “do not start a blog”, as “that will only establish your lack of seriousness as a scholar”. This may have been good advice in 2007 (when I defied the advice to start this website). Maybe it is good advice still and I don’t realize it yet. But here’s my estimate of the impacts so far:

Blogging has made me a better writer

It has meant I and my papers are much better known and cited by colleagues than otherwise

Opportunities cross my desk more often than otherwise

And, maybe most of all, I hold this blog almost directly responsible for several million dollars in research and program funding so far (paying for a lot of serious scholarly stuff). This number is exaggerated by the fact that I typically need to raise large sums for interventions as well as the research, but the basic point holds–for me blogging has (unexpectedly) paid back a hundredfold in scholarly work.

Yes there are costs and risks, but I think social media is too important for young academics to ignore. Accordingly:

If you want to tweet or blog under your research name, be serious. Let your research interests influence your blogging. Become a professional resource for people in your subfield. Be constructive and thoughtful not critical, and never use social media to attack colleagues. This will be a public good that pays back privately.
