TRAVELING FOR SUNY BUSINESS - shared governance

10/12/2019

 
I have the honor of being "Faculty Senator" for Farmingdale State College, which means that I represent Farmingdale at the "University Faculty Senate" (UFS). UFS is the legal channel through which the faculty influences system-wide SUNY policy. It meets once per semester to vote on resolutions and get policy updates from administrators.

The UFS trips are always a joy for numerous reasons:
  1. The colleagues that attend are fantastic people. They are like-minded in their desire to make SUNY as great as it can be in about all dimensions: accessibility, quality, diversity, etc.
  2. The networking opportunity is fantastic, you will always meet someone new. This Plenary I met the Chancellor, the chair of the Board of Trustees, and a mission-oriented CDO from College at Brockport who I think has many tools to help some challenges facing our campus. 
  3. The travel - Meetings are upstate more frequently than not. I am totally fine with this because I currently love  just about anything upstate New York. UFS travel, so far, has allowed me to visit Syracuse, Saratoga Springs, Cooperstown, and most recently Albany.

A more centered view from the front shows there are flags for each campus decorating the plaza.

So naturally, I had to find where our flag is. It turns out we are right near the entrance!

What a building!

seNDING MY STUDENTS TO University of Chicago Law school FOR A DAY

10/10/2019

 
I have to travel to Albany today as Farmingdale State College's "Faculty Senator". It's a big honor and a very enjoyable aspect of my job. 

My "Game Theory for Business" students (ECO 372) will be "attending law school" for the day, as I will not be there to challenge them.

By "attending law school", I mean that they will be watching a lecture from the University of Chicago School of Law on the problem we have been studying for the past 2 weeks: supply chain holdup.

The video is embedded below, but can also be accessed at this link.
Many interesting examples come up in the video. We have been studying a particular example of an upstream firm holding up a downstream firm (e.g. the GM -vs- Fisher debacle of the 1920s).

What I like about this video is that it includes examples of an upstream firm, like a natural gas or oil supplier/refiner, being held up by a downstream firm, like whoever owns the pipelines to transport these resources.

The contract solution presented in those industries is the take-or-pay contract: the downstream firm has the obligation to pay the upstream in accordance with the terms of the contract, independent of whether they actually take delivery of the resource.

This commits the downstream firm to not hold up the upstream firm - it has to pay the agreed to amount whether or not it takes delivery. 

ECONOMETRICS IN ACTION: HARVARD DISCRIMINATION CASE - PART 2/? WHO LET THE ECONOMISTS IN?

10/8/2019

 
So the first tasty bits of economists starting to become more apparent in the Harvard case appears on page 50. 

It gets spicy QUICK.

LINK TO PAGE 50 
So the case is an argument about the appropriate econometric specification.

Or if you're a fan of the lingo in the profession, it's an argument about the preferred​ specification.

Why do different sides have different preferred specifications?

Well that's on account of greater philosophical concerns regarding econometrics and identification. Suffice it to say that, in practice, results can change wildly depending on the controls used in a specification. Which controls are "good" and which controls are "bad" is clearly a point of contention in this particular case. And in just about any empirical research, at the frontier there is an argument about the appropriate specification to use.

I need to read the case more thoroughly and read the expert witness report by David Card before I comment on the preferred specifications, but it seems to be as to whether or not to condition on personal rating and status in particular advantaged groups like athletes, legacies, children of faculty, etc.



EDITING a journal

10/7/2019

 
In 2017 I was elected Editor for the New York State Economics Association. (NYSEA)

Why?

I did this because it represented a tremendous opportunity, and being elected also felt like an honor, despite the fact that I believe I ran uncontested.

It's hard to say no to things as a junior faculty member. The nature of junior faculty life is also such that you get ample time to scheme, and this can lead you down all sorts of rabbit holes.

The previous Editor, Bill O'Dea @ Oneonta, provided big shoes to fill.

That said, there were numerous opportunities to improve the visibility of the journal.

So far, I have done the following:
  1. Get the journal listed on EconLit, the indexing service of the American Economic Association
  2. Get the journal back on Cabell's Whitelist (paywall, sorry!)
  3. Make the journal entirely open access via CC-BY-NC-ND licensing. (I'm a big fan of open educational resources)

Econometrics in action: harvard Discrimination case - Part 1/?

10/3/2019

 
Click here for a link to the expert witness report filed on behalf of Harvard by David Card (labor economist)

Click here for a link to the Judge's Opinion hosted on my Google Drive.


It's always refreshing to see that tools you teaching to students are regularly used in their daily lives.

Perhaps the best and most recent example of applications of econometrics is in the case filed against Harvard for discrimination against Asian-American students.

Any empirical economist is going to have a mega complex regarding his quantitative skillset, by which he means his prowess in econometric analysis. It is our comparative advantage over fields like sociology or other liberal arts. Anything they say you can't measure, you probably can, and we probably are arguing over it at this very moment.

Econometrics has the wonderful ability to quantify just about any social science phenomena one is interested in, so naturally this lends to understanding whether, statistically, there is evidence of segregation.

I plan to write more on this soon, but my favorite passage so far is on p. 34

"Mr. Hansen's models could lead a casual observer to conclude that race plays a
significantly larger role in Harvard s admissions process than it actually does...
 The models
incorporate far fewer variables than those prepared by the parties economic experts for this
litigation and omit many variables that are important to the admissions process. Compare [PX12
at 33 ] , with [ PD38 at 26 ]. Even Mr. Hansen's most complete model almost certainly suffers
from considerable omitted variable bias in light of the likely correlation between race and
important variables that Mr. Hansen did not include. Most notably, his models contain no
controls for socioeconomic and family circumstances that correlate with race and also affect
admissions decisions. See [PX12 at 33] . Given these deficiencies in the models, they are
entitled to little weight for the purpose of determining whether Harvard discriminates against
Asian American applicants, particularly given the availability of the experts far more
comprehensive models and the testimony offered by fact witnesses in this case. See Oct 19 Tr.
19: 19– 20:8...
 Hansen's models do suggest, consistent with other evidence, that Asian
Americans applicants excel in academic metrics; that tips for legacies and recruited athletes
result in more white students being admitted; that a projection of Harvard' s class based only on
the profile ratings, academic metrics, and athlete and legacy statuses is incomplete and results in
a projected class that is vastly less racially diverse than the one Harvard achieves; and that ,
absent any consideration of race,Harvard s classes would have drastically fewer African
American and Hispanic students."

open educational resource Survey Data

6/28/2019

 
A few colleagues and I have interests in pedagogy research, and started to explore open educational resources. To dip our toes in the water, we wrote a brief survey about students perception of open educational resources as it pertains to their educational experience. You can find a copy of the survey in the box below. 
In the spirit of open access, the survey data from Qualtrics (with all identifiers removed) is available in the file below.

I may write further about this project here on the blog in the future.

THE Sunk Costs Fallacy as an evolutionary mechanism

3/6/2019

 
A group of colleages and I have been thinking about the sunk cost fallacy a lot lately, contemplating at its prevalence and the possibility that it may be a features rather than a flaw.

So I wrote a cute story about it.
 
Assumption -> in caveman times, life expectancy for infant born with n guardians (parents/elders etc) is higher than life expectancy for infant born with n-1 guardians.
 
(written in my finest caveman dialect)
___________________________________________________________________________________________________________
Grog and Urg are male and female cave-persons, respectively, who share cave. They are part of local tribe, where each member serves distinct role. Grog is hunter for tribe, Urg is gatherer. Grog and Urg are familiar with birds and the bees, and are expecting baby Grug in many moons.
 
Suppose, in waiting for Grug to arrive, things between Grog and Urg deteriorate. Grog begins long think about Grog, Urg, and baby Grug.
 
First, picture a version of Grog that “thinks at the margin”. His decision to leave the cave (and Urg) would be made by weighing the benefits of leaving Urg against the costs of leaving Urg. Among the benefits may be more disposable income, and possibly more leisure time. Among the costs would be the possible disutility of living alone, and the uncertainty regarding baby Grug’s survival. If Grog doesn’t care much about baby Grug’s life expectancy, and therefore doesn’t care about passing his genes to offspring, then his assessment may be that the benefits of leaving Urg exceed the costs of leaving Urg, and they separate. Grug is raised with one less guardian. If baby Grug really does have a lower probability of survival with one less guardian, then the probability of Grog’s genes surviving in the long-run is low if he thinks this rationally.
 
Let’s now imagine a Grog that falls for the sunk cost fallacy. This would be Grog looking back on all the time invested in the relationship. The time spent fending off wolves from cave to protect sleeping Urg, the times Grog went without food so that Urg could eat, etc. These sentiments make him overestimate the cost of leaving, at the margin. So Grog continues to invest in the relationship: continues to fend off wolves, give Urg his gruel, etc. The result of his continued investment in the relationship is that Grog and Urg do not separate and raise baby Grug together. So, it’s possible that Grog falling for this sunk cost is really his lizard brain trying to commit Grog to propagating his genes- the child has a better shot at making it past infancy with both Grog and Urg together. So he falls for the sunk cost fallacy and baby Grug has a better shot at survival. Furthermore, Grug has better odds at surviving long enough to have a child and pass the genes responsible for this behavior to the next generation. Probability of Grog’s genes surviving in the long-run is higher than the case above.
___________________________________________________________________________________________________________

So what is this story really saying? Alexander McQuoid paraphrases my story in the following way:
Sunk cost fallacy helps overcome inefficiencies associated with externalities? If I only think about my private forward looking utility, I will systematically undervalue actions that impose externalities on the community, which leads to long-term inefficiencies that can lower my ability to pass on my genes? So systematic selection of genes based on those that make decisions thinking about sunk costs, not just on the margin. 

UNDERGRADUATE ECONOMICS RESEARCH

11/1/2018

 
Related to the following post on reddit.com/r/academiceconomics

Q: I'm a freshman at a not so great school for economics (didn't get into the big name schools and this was cheapest option), but I really like economics. In high school I won a bunch of awards in economic competitions. Not trying to brag, just to prove that I'm interested and have some aptitude.I've reached out to my current professor and other professors in the department but none of them are really doing any research. The few that are just want upperclassmen to do data entry work for a long term project. Most people at my school just take economics to work in business. I was recommended to do the MA in four years but that seems like a long term thing.

A: 

​My perspective as a tenure-track faculty member doing empirical research at a small public 4 year degree granting school:
 
You are a freshmen, so unless you are a significant outlier, you've not been exposed to econometrics.
 
Many faculty may hesitate to have you do anything other than data entry if you haven't taken econometrics. Why? Econometrics is a language that you need to learn to speak fluently before you can really add value beyond simple tasks like data entry and literature reviews. Don't forget, having you involved isn't costless, many of us are quicker at these tasks on our own or with colleagues, rather than having a student involved.
 
So given I have to invest time in the relationship, I need to invest that time in an optimal way. What is not optimal is for me to attempt to teach you econometrics just for the sake of having you as an RA. You'll take the class, it's a requirement, so this just wouldn't make sense. This is absolutely nothing personal, it's just prudent time management.
 
I poach the top 2-3 econometrics students as research assistants and co-authors on wild ideas we have a common interest in, but wouldn't really consider students early in their career because they need to develop their intuition more through exposure to the coursework. If you think you can add value beyond just data entry tasks, then signal it, show them you can add value. It would definitely shut up my concerns if you walked in with some code and preliminary attempts at addressing an interesting question.
 
You shouldn't discount the experience of doing simple tasks like data entry at the very start of your career. You signal your interest in the field and that you are serious about the profession, you may form great bonds with professors or other RAs, you will do a lot of reading that will help you write better, you will learn nuances of cleaning data, etc etc etc.
 
My guess is the regional Fed would send you info about one of their public outreach programs, the Fed challenge, etc, as ways of being exposed to economics and research. It's not reckless to reach out, but I wouldn't hold your breath.
