Economists do care about inequality, and do support policies to reduce it. They don't believe markets are perfect, or even that markets should be used at all in some cases. A large fraction of our work is on these topics. Spread the word, and reduce some of these misperceptions!
Why can't the Australian government make rational decisions about anything to do with Covid-19 vaccinations?
Latest case: you can't register overseas vaccinations unless the vaccine was approved in Australia *at the time of vaccination*, regardless of whether it is approved now.
π’In mid-2023 I will be leaving the Michigan, and joining the Australian National University.
More below but TLDR:
1. I will miss UM and its people. It's been a fantastic place to launch my career.
2. At the same time, I'm very excited to join a very exciting new group at ANU!
πππ§πππ¦π’π π₯ππ¬π¬π¨π§. No one should be allowed to leave school without showing they understand Bayes rule. Whatever the cost. Next pandemic, people will be ready to understand the statistics they are seeing.
A take on the minimum wage I think is uncontroversial. Economists who say they don't want to raise it are not saying that they don't care about helping low income workers or reducing inequality. They are saying *they* think there are better ways of achieving those ends.
Nice to see my JMP come out after years of work! π

π§΅:
PSA: When economists say a policy is "optimal", that means it maximizes a particular objective in the model they wrote down. That's not interchangeable with "you should adopt the policy". It does not even imply you could actually *get* the policy adopted.
ππππ¬:
1. Many factors affect your JM outcome beyond the quality of work β you cannot infer much re: its quality from outcomes
2. It says even less about your ability as a researcher
3. It says NOTHING about your value as a person
4. 1-3 more true this year than ever
Message from Esther Duflo (AER Editor): Referees need to be more positive, and top journals would publish more papers. "There's no page constraint on journal issues."
People in our (or any) profession would be happier and healthier if we didn't imply to each other that doing things other than work is a waste of time.
Dear (mainly Aussie) non-economists,
The following are not contradictory.
1. Economists care a lot about unemployment, GDP etc, inequality etc.
2. We don't think overruling the RBA helps with all that, and probably makes things worse in the long run. It has in other countries.
Reasons to do a PhD in economics:
1. Itβs intrinsically rewarding.
2. It leads to jobs that are intrinsically rewarding.
3. Great job prospects in other ways. High pay, option to have influence.
Reasons not to do one:
1. Most find it stressful.
2. Other paths are also good.
Real, non-trollish life advice:
If you're a smart young person and you really want to go to graduate school, then by all means go. But if you're on the fence, probably don't. That's not where the action is. And it's not where the action is going to be for the foreseeable future.
Our pre-birth *hospital-run* course told us that breastfeeding -> baby iq higher by 7 pts.
I looked up the study. It had motherβs IQ and did not control for it. When they did it went away.
Even for researchers more honest than that, controlling for observables is not enough.
Thread of bad maternal health research that caused needless panic.
1. Breastfeeding was linked to higher offspring IQ. But the effect disappears in sibling control studies (same mother breastfeeds one child but not the other)
Some non-contradictory things:
(1) You can get into an econ PhD without real analysis
(2) Those who do have other apparent strengths
(3) Doing it will help you get in, ceteris paribus
(4) For some people it's useful during the PhD and after; for others it's not
Subtweet (1/2). Some of you, whom I respect a lot, have a flaw. While professing to welcome conservatives to economics, you post tweets that disparage people or their research if that research conflicts with what you think (in a way you wouldn't if it aligned with your views).
It's frustrating to see people attack economics for being something that bears no relationship to how I experience it.
People misuse economics. Sometimes that is academic economists. Mostly it isn't.
There are *plenty* of valid criticisms of econ. Focus on those instead!
Plenty of new evidence today that straw versions of economists and economics live rent-free in some peoples' heads. If only real economists could live rent-free too...
Dear media friends,
*Please* donβt cite economists as being renowned, leading, great, or anything like that. Especially if they arenβt those things, but the point is more that you should explain arguments, not appeal to authority.
Thanks. βΊοΈ
More than two years after I completed my PhD, I have regained access to the data required to publish my second dissertation chapter!

Hateful attacks on Russians in the US & elsewhere are misguided. We should welcome them & invite more. Especially (not only) if they have useful skills to poach! Reverse boycotts, deliberately going to Russian restaurants, help Russian immigrants etc., seem better than boycotts.

I find this discussion about which fields are smartest based on GRE scores particularly annoying on so many levels.
(1) The GRE is a silly narrow test.
(2) Selectivity based on GRE tells you nothing without lots more info.
(3) Even if it did, who cares??
Plz stop.
Always nice to see a paper come out in print.

This paper is unusual in that it proved simpler than expected. We draw parallels between the economics of tax evasion and tax misperception, and provide what we hope is useful policy analysis for both.

IMO, the accusations donβt need to be proven for this to be a very bad decision.
Itβs not a court. Itβs a decision to promote someone who may pose a major risk to others, and will rationally deter them from participating in an important institution. It also signals indifference.
Roadmap paragraphs at the end of the introduction are useless. In fact, I am not sure I have ever heard someone say they liked them, but know many who say they feel they have to be there because other people think they should be. Do some of you actually like roadmap paragraphs?

I rapidly learnt during my PhD that the answer to the usually silly question of "You have the same surname as X. Are you related?" was now usually yes.
A quick note on submission to the new JPE Microeconomics.
They really are efficient. Sample of 1 for me, but backed up by othersβ experiences, I think?
Folks, please stop trying to remove basic math from high school. Or from college entrance requirements. Youβre setting kids up for failure in the century in which they are going to live.
Malaria nets may have protected hundreds of millions of people from one of the most deadly diseases in human history. But they have also occasionally been used for fishing. So it's impossible to say whether they're good or not.
In our column, Matt Lilley and I argue 2 points:
(1) ATAGI totally ignores benefits to others from AZ vaccination now rather than Pfizer later
(2) Those benefits are very large
The benefits to others would be more than enough to convince us personally.
π§΅Time for a thread on my six amazing
@umichECON
job market candidates this year! They have a fascinating array of topics! Take a look, and you'll see why I think you should hire them.
How can we reduce hierarchy and the concentration of power in economics? Wherever you see people have power over others, it ends up getting misused by some, and in some horrifying ways.
Something for Australian (and other) journalists to learn here.
There is a perception that forecasting recessions etc. is a meaningful part of what economists do.
Virtually none of us try to do that. Aside from being very hard, itβs just not really what economics is about.
The right way to predict recessions: admit you can't.
Every year there is a 1 in 6 chance. Like rolling a die, get a 1 you have a recession, 2-6 you don't.
Can raise/lower that probability a little bit based on circumstances. But we don't know enough to change it very much.
Given how slow the TGA is at approving any of these, it rules out most people who got vaccinated overseas, in countries that (unlike Australia) did not totally bungle their vaccine rollouts.
3yo: I want 6 tomatoes
Me: That's a lot. How about 4?
3yo: No, I need 6.
Me: I'm not giving you six. How about 5 then?
3yo: No! I want 3 tomatoes.
Me: Ok, done.
Anyone got a theory of bargaining to explain this set of events?
An underrated point about externalities:
Suppose an action of mine benefits you. Even if I am perfectly altruistic in the sense that I value a $ of benefits to you on par with a $ of costs to me, that doesn't change the external benefit to you or the argument for a subsidy.
With vaccine passports etc., on the horizon, this is consequential.
It boggles the mind. Someone consciously added this rule in there. What could the logic be??
Q: Why are people so comfortable with discrimination when it's in the form of visa and other such restrictions which prevent the best employee from getting the job?
(2/2) I know conservatives who are deterred by this, from Twitter at a minimum, and in some cases from academia. They are good people whose views are valuable. And before people say we aren't hostile to them on here, this is about how they perceive it. Not how you and I do.
I hope all you job market candidates applied to the Australian places. It's a beautiful place to live, with wonderful landscapes and wildlife as well as great economists.
PSA: I am a public finance economist. I study the economics of tax and fiscal policy. Asking me to do your taxes is like asking an art history major to paint your room.

Long before your PhD, one has to be deeply incurious not to take a proof-based math course before starting your first pre-doc. That and a math GRE of 171 should be required to even be considered for one.
4. The govt has other tools to slow the economy, which have different distributional consequences. It chose not to use them, and in fact to be expansionary instead. The RBA now has to use the tool it has now to do the job.
I *think* Josh Angrist's class and papers have increased my knowledge of econometrics. But can I be sure??

The Djokovic saga was ridiculous. But rather than dedicating so much attention and news space to a rich sportsperson prevented from becoming richer by playing more sport, how about we focus on the refugees who have been locked in the same "dingy" hotel for months or even years?
I am being expertly trolled by my 2yo.
Me: What color is my hair?
2yo: Silver!!
Me: WHAT? There's another color.
2yo [looking carefully]: Yes! White! I see some white!
Me: WHAT? There's brown!!
2yo [looking even more carefully]: There is! There's a little bit of brown!
People make jokes about having wait to get healthcare in countries where it is government-run. But in my experience it's the opposite. Delays are much longer in the USA. Does that match others' experiences?
Since we Australians are ahead of the rest of you, I thought I'd provide a public service by letting you know from the future that Christmas this year is a nice 30Β°C (86Β°F). Happy holidays! πποΈ

Is OLS valid in your setting? DiD estimators? Regression discontinuities? Propensity score matching? We show that as tββ, one of us will show you're doing it wrong. An implication for applied work is that you should give up and do theory.

Most people donβt use calculus day to day, so we shouldnβt teach it. OK.
Most things taught arenβt used by most people day to day. Eliminate all sciences, math above basic numeracy. Most of your vocabulary. Art, physical education.
Cut it all and do school in 3 years I guess?

Dear journalist friends,
When you are covering academic work, please link to it or AT LEAST say whose work it is.
DO NOT only cite the most senior sounding author.
If at all possible, ask the authors to comment.
Pls RT / send to this to all journalists you know.

Public Finance people, consider this great workshop if coming to Australia is an option for you! The talks are great. More than that though, it is a lot of fun, with an unusual mix of academics and economists in government.

I think it goes without saying that we need to demand more from leaders in the economics profession than writing insightful papers, and not having been proven guilty of misconduct.
6. Back to caring about inequality, we do not favor profits over wages, rich over poor people, or anything like that. In fact, we study and care about inequality a lot. But we will argue hard for better policies to reduce it, and against ones we think will be ineffective or bad.
