How to talk about how awesome your work is without sounding like a jerk (in an academic paper)

Being a woman, and a woman not at a top 10 institution, in a field in which there is little to no double-blind reviewing, I have to walk a very fine line when promoting what is novel and new about my work compared to previous work.  This is especially hard because I do really innovative work that ends up getting cited a lot and taught in classes but faces a huge amount of push-back from the people who don’t think that way.  (When I put it like that, maybe I’m not the best person for giving advice given my lack of top general interest journal publications.)

Anyway, don’t say that you’re the first person to do something unless you’re an asshole at a top school.  They are always wrong.  They have always not done enough literature review.  But that doesn’t kill them whereas it is the death knell for the rest of us.  Don’t do it.  (I review a lot of papers and see this dichotomy in action– asshole reviewers are so pleased to bring their work to the attention of the famous white dudes, but are insulted that junior scholars should not know their important paper published 30+ years ago.)

When you’re an asshole at a top school, a good strategy is to do an extremely light literature that only cites top general interest journals.  That makes it look like your paper is new and innovative.  And people believe it is because your work doesn’t get sent out to the other people (women, junior scholars, people not at top 10 schools) who have worked on the same question because the editor doesn’t know they worked on it and you didn’t cite them, so how is the editor supposed to know.  Yes I am still really bitter about this.

When you’re not that asshole, you have to do a really complete literature review because if you don’t cite someone, the reviewers take offense and think you haven’t done a thorough lit review.  You can get away with not citing things that aren’t in your field (but I cite people outside anyway because they do work I think economists should know about– this is part of why my way of thinking about things is so innovative– innovation in economics is what another field discovered 30-50 years ago…).  You can get away with not citing things that got published in second tier field journals or lower, but if it was in a top field journal, it needs to be in your list of works cited.

Now, if you’re a white male asshole at a top school, you can make your career out of proving another top economist’s top general interest paper was wrong.  Or, if it’s a female top economist, all you really have to do is harshly question it.  If you’re female and you do this, it can destroy your budding career unless you coauthor with a senior top male economist or two who will take the credit and shift the blame to the bad paper author.

All of that aside… and back to the topic that inspired this post.

If you are a woman/non-famous person, how do you make it clear that your paper is doing new stuff without insulting your potential reviewers?  The answer, my friend, is data limitations.  Or, if it is much older work, new technology.  They *couldn’t* answer the question you’re answering because their dataset wasn’t good enough.  No fault of theirs.  You have something new to add because of your great luck or your hard work.  This probably explains why I am forever amassing new datasets instead of writing papers with the sets I already have.  (That and I’m a dilettante).

So, is this good advice?  I don’t know.  My career looks like a glass ceiling– I am very good at publishing at top field journals, but have yet to hit a top general interest journal.  Some of this is because other than my job market paper I didn’t send my work to top field journals until after tenure, but some of it is that I still don’t know how to play the game perfectly and my reputation is not such that I get the benefit of the doubt.  I still get desk rejects with useless comments for papers that end up getting accepted with minor revisions at similar journals.  There’s a lot of crap shooting going on.

(Disclaimer:  #notalleconomists are assholes, #notalltopeconomists are assholes.  Some are really nice and are generous with their citations and work and try to write the best papers they can because they care about economics and policy.  Others care a lot about playing the publication game.  I’m sure it’s similar in many lines of work.)

Ask the grumpies: whether or not to purchase insurance

H.I.P. Person (Home Insurance Purchasing Person) asks:

How do you decide if you need insurance for something? We are updating our home owners coverage and they are peddling the following:

1) service line coverage –  up to $10,000 per event
2) systems coverage (a/c, hvac, water heater, furnace, and the like) – up to $50,000 per problem
3) sewer back up (?? not sure of max coverage)

We live < 75 miles from the coast; <20 miles from two major water coastal inlets but  not in a flood zone. What hurricane related insurance should we own? The policy comes with wind/water but not flood and they don’t really want to sell us flood (they are offering #3 instead).

Are any of these worth it?  What price point would make them worth it or not?

DISCLAIMER:  We are not financial advisors.  Get advice from real professionals or do your own research before making important monetary decisions.

So in economics, you purchase insurance when the expected utility of the insurance is greater than the cost of the insurance.  So, assuming you knew how your utility function was shaped (the important part for this purpose is that you know your coefficient of risk aversion, in this case specifically how much you hate the possibility of loss), and you know the probability of a bad thing happening, you just multiply that probability by your expected utility plugging in the amount you’d be out if the bad thing happens and then add the probability that the bad thing doesn’t happen and multiply that by your expected utility plugging in the amount you’d have if the bad thing didn’t happen.  Problem is… in reality, we usually don’t know the probabilities of these negative events occurring (or even what those negative evens could be!) and we definitely have no clue about what our utility functions look like.

So how does one decide what to get insurance on in reality?  Well, if you have rough ideas of probabilities, you can look at the expected value of something happening.  Expected value is like expected utility, but it tells you what the break-even point is assuming you have no emotions.  You’re neither a gambler nor risk averse.  But risk averse you can look at those numbers and think to yourself, “How do I feel about this calculation?”  In general, the insurance company is out to make money, so they’ll be charging more than the expected value of the thing happening, but does the amount more that they’re charging seem reasonable to you?

If you don’t know the probabilities of something bad happening, you can still play with worst case scenarios:  If the bad thing happens, what would you have to pay out of pocket to fix it without insurance?  What would you have to pay out of pocket with their insurance?  Is the peace of mind for the difference between those two numbers worth what they’re charging?  (And again, if you have rough ideas of how probable these events are, you can factor that in as well).

Another thing to do is to google around, preferably with reputable sites, to see what kinds of insurance are usually a good idea and what kinds are generally scams.  You can ask people around you too, though people often do things that don’t make sense if there’s good marketing on the part of the insurance company or if they’re more credit constrained or risk seeking than you are.

An important thing to note is that you want insurance to insure against risk.  You don’t want it as a pre-payment for things you’re going to pay for eventually.  You don’t want a high monthly cost if you can avoid it by sharing some of the pain should disaster strike through a higher deductible.  The goal isn’t to save money, it’s to smooth your consumption over good and bad states of the world.  Don’t try to beat insurance– in the best states of the world you give them money and they never give you money.  But you want it there when disaster strikes if you can’t handle the disaster on your own.

If it were me, I’d definitely eschew the service line coverage unless it was really cheap– we can afford a 10K emergency.  Since the limit is capped, it is not actually useful insurance unless paying up to 10K would be devastating.  (Capped insurance is often a red flag– if they stop paying after a certain amount is spent you may be better off self-insuring because if something really terrible happens they’re not going to be much use, and self-insuring means you’re not paying for the additional administrative costs of going through them.)

Systems coverage again, we probably wouldn’t pay… replacing a/c, hvac, water heater, furnace etc. is all stuff that has to get done some time anyway (and none of these should cost 50K, unless that’s including the damage after a water heater explodes or something) so paying them is like pre-paying for bills you’re going to have, but it is likely you’re going to have less choice about how to make those replacements and you’ll be paying their administrative costs over what you’d be paying if you did these things yourself.  And, again, it’s capped.  This is unlikely to be good insurance.

Sewer back-up is the only one of these that doesn’t sound 100% scammy.  Check all your other insurances to see if this is covered under them.  Estimate how much a sewer backup could destroy.  Make sure that it’s unlimited covered and not capped and there are no other strings attached.  Think about the probability of this happening.  Look at how much they’re charging for it.  Then go with your gut.

We have no idea about hurricane insurance.  The internet has a bunch of pages about it, noting you should get wind and flood on top of home, but I’m not getting a good idea of what numbers you should be looking at or even how to make that calculation.  You may also want to look into the different deductibles they offer, because none of these sound particularly cheap, but it may be that if you have a high deductible the insurance cost will be more reasonable (assuming you can afford the deductibles).

Good luck!

Grumpy Nation, do you have any better advice for H.I.P.?

 

Ask the grumpies: Private vs. public colleges

Sandy L. asks

Cost benefit of public vs private college. What is the value of the network, etc.

The question isn’t really about public vs. private.  Berkeley is going to open a lot more doors and have a much more impressive network than the expensive small regional private liberal arts college one of my sisters-in-law went to.  The question is really about the prestige of the school.  There’s a lot of interesting new research on that topic.  And the answer is that, first off, we don’t really know, and second off, it is nuanced.

In general, for your white upper-class/upper-middle-class kid, it doesn’t really matter where they go.  Harvard, top flagship, regional state school– it just doesn’t matter.

For your lower income family, minority, etc. etc. etc. student, it can matter quite a bit.

But even with that mattering, some schools are better than others at elevating kids into higher socioeconomic status.  And some schools (like Harvey Mudd) are phenomenal at elevating low SES kids, but don’t actually admit very many of them (that $72K/year sticker fee and all).

I’m too lazy to source and cite this, but if you’re interested in finding out more, flip through the NBER working papers abstracts for the education group.  If you need to narrow your search window down, Carolyn Hoxby is a good place to start– she’s written extensively on this topic and cites a lot of the other work that has been and is being done.

Ask the grumpies: Better political and economic systems?

Solitary Diner asks:

Working in an inner-city clinic, I think a lot about the political and economic systems that contribute to the poverty and marginalization of my patients. What do you think can/should be done to make the world’s systems more fair to everyone?

Yeah, these aren’t hard questions at all.

Most economists favor socialism-lite.  We think government should intervene in cases of market-failure when the benefits of intervention outweigh the costs of intervention.  In practice that usually means something like what Europe has (not entirely though), with a lot of focus on making sure that the social safety net is high for everyone and even more focus on early childhood equality.

Of course, the rational-actor model is blind to structural inequalities stemming from racism, and many of our models seem to think that sexism is a feature, not a bug (they start out with the assumption that women are differently-abled and that’s why they get paid less… even in jobs for which they have comparative advantage).  I don’t know how to get rid of -isms.  I can tell you that Marxism doesn’t do it.  Nor monarchy.  I presume a benevolent dictatorship would even have difficulty, though maybe it would have a shot depending on how long the dictator can stay in power and how good they are at forcing behavior.  If we could somehow manage to get rid of segregation, that might also help since so many of our policies use geography as a way to discriminate.  Though perhaps changing those policies to be less local could help.  There’s no reason, for example, for local property taxes to fund schools.  Of course, we would no doubt still see inequalities from “voluntary” requested donations.  Paradise requested a $500 donation from every parent at the beginning of the year, and got it from many– less wealthy areas are not able to do that.

So… what should be done?  More socialism with a focus on the children.  What can be done?  Beats me.  :(  If I knew the answer to that, I’d tell it to one of the economists who hangs out with Bill Gates and they’d get to work!

 

Ask the grumpies: Privatizing nation’s air controllers?

Crone asks:

opinion on privatizing our nation’s air controllers. I oppose but was told the whole system should be moved to computer based GPS system and then Highways in the Sky for planes could be free form making flights faster and private industry can do this more rapidly than government. (I was in social situation so could not say I have never known a single computer system that did not ‘go down’ or ‘have ‘undocumented features ‘ so how would that work…) The topic of pipelines that ‘will not fail but ALL LEAK at some time’ had already come up.~~ I had been assured I was wrong on that point and ignorantly female. SO, back to air controllers: If this would be profitable for private companies to do why isn’t it done profitably or better by public government?

OMG, the WORST IDEA. OMG OMG OMG.

Well, it’s only the WORST IDEA if you think that airplane passengers are more important than prisoners. If you think prisoners are people too and should have rights, then privatizing prisons is actually the worst idea and this is only second worst. I guess there’s also privatizing foster care systems… if you think all people are equal then that might be slightly above air traffic control but still below prisons in potential harm done by privatization. (Foster care systems empirically aren’t as bad as prison systems, even though the potential is there to be as bad. This has to do with better state oversight.)

I had a section on privatizing public systems in one of my classes last semester and students brought in stuff– if I’d known it would come up as an ask the grumpies I’d have taken a picture of the whiteboard commonalities of when it works and doesn’t that we came up with. It can be ok, but it depends on a lot of stuff and it really shouldn’t be something where you know, people could die.

Ugh, so no, not you being ignorantly female. There’s a reason there’s a role for government for various systems.

We generally think that there is a potential role for government intervention when there is market failure in the competitive markets.  One form of market failure comes from monopolies.  Something like air-traffic control is what we call a “natural monopoly”– natural monopolies occur when it just doesn’t make sense for more than one company to be in one market.  A lot of utilities are in this kind of situation– where it doesn’t make sense for two companies to lay down pipes or what-have-you.  (You can also have government-private partnerships, where, for example, the government owns the rail-lines but allows different companies to pay to use them.)  Air traffic control is an example of a natural monopoly.  At an airport, it makes sense for only one company to do the air-traffic control.  Any more could lead to planes, for example, hitting each other.

The government in this situation could still allow private contractors to bid on the ability to be that one company doing all the air traffic controlling.  Unfortunately, air traffic control benefits a lot from experience and there are switching costs when an old company leaves and a new one takes its place.  Those switching costs could lead to not just inefficiency but also death.   Finally, oversight is really important with privatization.  Unlike the government, companies can just go out of business when they cut costs so much that people die, so they don’t have as much of an incentive to stay safe when it means cutting into profits.  Government can combat that by making it costly for them to cut corners before someone ends up dead, but that oversight comes at a cost.  Those costs could be large enough (and the possibility of bribes could be high enough) that it makes sense for the government just to do it itself.

 

Conversation with a friend about political economy: Two economists lament

In case you wonder what economists talk about when they get together…

Economist 1: I have a friend who is not speaking to me because I sent hir an article by Alan Krueger saying that a $15 min wage is probably too high (after zie made a big deal on social media about attending a “fight for 15” rally). And I have another friend who is avoiding me because zie voted for Trump and knows I think that’s despicable. I think I quit.

Economist 2: Don’t quit! Can you tell hir 15 is probably right for [expensive city]? You’re better off without the Trump supporter in your life. Keep fighting for evidence based policy, even if you only get to see people who truly understand once a year and at work…

Economist 1: I told hir I thought it was right for [other expensive city]. I was nice about it (I thought) and I sent it to hir over email – not publicly on Facebook. But zie’s ticked off anyway. And yes – I probably am better off without the Trump supporter but I’m so disappointed in hir and I’m sad about it.

Economist 2: Maybe if we lived in a different world with more social support and greater support of people getting education and also more automation…

Economist 1: Yes. Exactly. I don’t like arguing with people who are on the same side but… This friend was a strong Bernie supporter [#notallberniesupporters], which I guess explains a lot. Sigh.

Economist 2 [still imagining a theoretical world in which a $15 minimum wage is imposed across the US]: Probably what would happen though is we would have a highly functioning black market with little to no worker protections. *sigh* Reality just doesn’t care about ideals and opinions.

Economist 1: The side that *supposedly* cares about science and evidence won’t listen when the science doesn’t perfectly support their ideals. And everyone hates economists :(

Economist 2: We were briefly listened to under Obama… Everybody should love us– we have a hand for everyone! There are very few one handed economists!

Economist 1: Exactly!!! But instead we get crap from BOTH sides.

Economist 2: It really makes one not believe the median voter model. What bunk! (To think I so strongly believed in it prior to the Gore v. Bush election. How naïve I was.)

Economist 1: Maybe if we didn’t have gerrymandering and the electoral college…

Economist 2: Excellent point.

Have you lost (or gained) friends over politics recently?

Ask the Grumpies: Where to learn economics?

Leah asks:

I’d love to learn some basic econ. Where’s a good place to start that is not too arduous but is also accurate?

I know there are a lot of Econ for laypeople books out there (Freakanomics being the most famous), but when people ask me this question I always stick to two textbook recommendations.  The first is the Intermediate Microeconomics by Robert Frank called Microeconomics and Behavior.  The second is Public Finance by Jonathan Gruber.

I love Frank because he discusses microeconomics in a way that contrasts how the rational person would behave with how people actually behave.  This I think makes the theory more believable and more powerful.

Public Finance I really think ought to be taught in high school.  If you want to understand the role for government, it is a must read.  So much of what is going on with healthcare right now violates basic economic principles and after reading about adverse selection, you, too, will understand why.

Note for these that you do not at all need to buy the most recent edition.  The 1998 edition of Frank is fine for understanding the basics.  The first edition of Public Finance by Gruber is still a fantastic read.  Get whatever is available and cheap.

What economics tomes/videos do you recommend, Grumpy Nation?
