Do US Student Loan Problems Produced As The Results of Systematic Errors?

Before answering the above question, one needs to understand what is systematic error in the education industry, who are the producers and sources of these errors as the first step to understand the issues.  There are four major players (1). Regulators; (2). Administrators; (3). College decision makers and (4). American public i.e., students and their family.  The first-three group, as it has discussed in this BLOG are endogenous to the system, while students are exogenous, i.e., they do not have the power to influence the outcome.

When the regulator permits the for-profit institutions and the student loans servicing companies to go-public or selling their stock in Wall Street then we have another entity added as an exogenous force.  Therefore, all together there are 4 endogenous and one endogenous variable.

Let us define what could be the systematic errors in the education industry?  This type of errors are well known in the Physic research area where researchers collect information, data or events, based on tainted equipment that consistently produces biased outcomes.  One needs to know what is the desirable or optimal outcome before she or he is able to make the inference that other than the optimal outcome is the undesired or tainted results.  In the education industry the equivalent of “tainted outcome” are numerous such as lower graduation rate, pilled up student loans, unaffordable tuition, lower delivered education qualitys, higher operating cost, inefficiency and many others.

Now, let us take the following important questions:  Who are among these subsystems (endogenous variables) are the instruments that could have direct impact to generate the tainted outcomes?  The first-three members of the endogenous group have the power to make the public policy, while the fourth member of the group may have the power to affect the public interests through corporates’ policies.

  • Regulator/law makers’, government and college administrator’s objectives should be consistent with the tax payers’ interests.  If not then they potentially are the sources and producers of the systematic errors.
  • The Wall Street’s interests are leaning toward the corporates’ objective is to make profit.  Therefore, it may generate conflict with the tax payers’ interests.  This group will have higher probability to make systematic errors.

Things are out-of control if all these endogenous forces directly or indirectly working against the public interests.  The $1.5 trillion piled-up of current student loans which show no sign of slow down is nothing but showing the results of different policies that have been implemented by these endogenous groups caused the systematic errors.  Therefore, there is no cure for the current US student loans issue, until after these systematic errors are managed, minimized or eliminated.

What Is The Guiding Principle To Manage An Institution?

The answer to this question is, it depends.  For public companies who sell their stock in the Wall Street—the CEOs often use the EPS (earning per share).  These companies are trying to beat the Wall Street analysts on the estimated EPS each quarter.  Otherwise, their stock price will be punished. Therefore, the motivation for these companies is profit margin.  This makes perfect sense for the for-profit entities.  The questions one may ask, will this EPS always has a positive correlation with time?  The answer is yes, so long there is a new innovation that will drive to the new product developments.  Otherwise, it will stagnant.

Let us turn our discussion to the education industry.  As the public may know–there are for-profit higher learning institutions and non-profit Colleges and Universities.  The for-profit certainly follows the Wall Street’s example.  Especially those institutions who are selling their stock in the Market.  Therefore, there is no surprise when the data show that attendees of these institutions are experiencing difficulties related to their student loans.  This may imply whoever permits these type of institutions to operate has made a suboptimal decision.

What about the non-profit higher educations?  What are the guiding principles that they look and apply in managing their institutions?  Do they have any guidelines?  Well, the School Board has the final say about a school policy.  Therefore, members of this Board also have to apply some sort of principles.  Did they?

If the current student loans data are the reflection of the results of these collective principles that have been applied in the industry for ages, then the answer is no.  Majority of the School Board and, therefore US Higher Learning institutions may not have a clear guideline when managing the school, except for using traditional metrics such as enrollment growth.  This student enrollment growth is equivalent with the EPS in the Wall Street.  Now that public may have a better picture what has happened.  This situation even more dire in the absence of strong regulations.

However, Adam Smith who is considered to be the Father of Capitalism has argued that including moral consideration when making strategic decisions produced results that are far superior than those of produced merely based on ratio or rational expectation.  Your thoughts?

2018 Nobel Prize Recipients and IRI V.2 On Simulation

2018 Nobel prize go to Yale and NYU, where one of the recipients, Laureate William Nordhaus’ research on the impacts of climate change on economic growth is based on simulations.  The world has spoken that simulation is a useful tool to predict uncertain future events, such as the impacts of student loans on economic growth.  The answer to this question is pretty straight forward–negatively affect not just the economic growth, but also income inequality.  The politicians love to use the DOW to measure how well the US current economy has grown in recent years.  This positive growth is welcomed mostly by the investors in the Wall Street.  Or few companies such as Apple or Amazon, and their shareholders are enjoying it too.  What about the working class?  Have their wages or take-home pay going up, parallel to the DOW increases?.  What about those who still have to pay their student loans?  Given the real problem facing the nation and the world, this is a life time opportunity for anyone to study this issue, and chances may not be that bad (stated with disclaimer) for those researchers to potentially be the future of Nobel prize winner.  The American public is eager to see which economist(s) represents, either the Freshwater of the Saltwater will win this important race.

It may not be a coincident why AAEA has just published an article on September 21, 2018 which urged the analytics community to think ahead of the curve, ie., a way from IRI V.1 to IRI V.2. Most people are amazed how predictive analytics can solve their business problems, especially in the education industry. That is obsolete–that was the things of five years ago.  Many months ago, the Association of American Education Analytics and Data Scientists has proposed to move away from IRI V.1, which is statistical based approach toward stochastic simulation, that combined the estimates from statistics, feed into mathematical programming to find optimal solutions.

Decision makers cannot just make strategies based only on one option, but need to see results of different scenarios, before the final decisions are made.  Statistical based business analytics just gives what the optimal solution, given the past events that have occurred.  In other words, a data scientist makes inference based on past or historical data.  The question is what next?  A college decision maker can make strategic decision based on the results, assuming the “world” that produced the data did not change.  In reality the world changes every nanosecond. The environments where the organizations are operating, changing constantly.  For example, the CEOs of any companies who are exporting their products to the world market, need to anticipate what is the impact of stronger US dollars and what is going to happen when the administrators ignite the trade war?  Past data cannot answer this question in totality, because there is no data that have simultaneously capture these two events.  The impacts can be accessed with n possibilities using simulation–IRI V.2.

Graduate Students and Future Data Science Professionals: Notes On Career Path

Now that you may have or have not read the following article which we have shared and written in our BLOG many years ago.  Apparently, there may have some correlations why you have chosen to attend a Masters degree program in Business Analytics or to become a future data science professional with the information that we have shared in the past several years.  This article has confirmed AAEA’s early hypothesis, in that the US is experiencing serious shortages for data science professionals.  This is the reason why many higher ed institutions are offering the program, starting in the past a couple of years.

To the current graduate students, the Association has a little suggestion while you are still in your program.  It may help you to take useful classes or are thinking on doing a summer internship before finishing your graduate program.  First and foremost, your classes only fill a-half of the knowledge and expertise in preparing you as the future data scientist.  The other half is coming from the real world.  How can you fill and get the experience from the real world in data science, unless you have been or are employing in the industry or your current company.

If you start fresh the second career as a data scientist, a few things that will increase the odd (with disclaimer) that your dream will come true are:

  1. Capitalize the real-world knowledge that you may have had in the past or currently.  For example, if you are, for whatever reason have received your undergrad in “soft” science which have forced you to work at a minimum wage company such as at one of the fast-food chain stores, you can and need to capitalize your past experience in the fast food industry.  Therefore, concentrate to understand what kind of data which you can analyze differently which will help the corporate office of that chain store may see your experience as important core competency.
  2. If you never been working, fresh after your undergrad graduation to attend the grad school, you need to think what do you want to specialize in?  For example, after the second and third year, a medical student has a pretty clear idea what he wants to specialize in and where he wants to work and live.  Becoming a brain surgeon, while making the top dollars, may not be fun for those who cannot cope with the work related stress, plus it took extra years to finish the residency program.  If you are unsure, a good start is looking at a grocery store shelf.  The next time when you go shopping at one of your favorite stores, look what are available on the shelf.  This may give your some future ideas what industry or even a company you wanna to specialize in?  Great grocery stores have a wide range of products from the pharmaceutical to fresh produce.  From breakfast cereal to jewelry.
  3. Do not avoid hard classes such as advanced econometrics or advanced mathematical statistics.  You got to have those, plus various programming classes where you can learn how to code using Python, R, SQL, C++, JavaScript,  etc.
  4. You got to have advanced managerial/microeconomics, managerial finance, and if possible managerial accounting.  Depending on what the super-super specialist that you wanna to be?  Think what a fellow in medical school training meant.
  5. You need mathematical programming classes where you will be taught how to model and run a stochastic simulation modeling.
  6. If your have a two-year program, try to do a summer internship after finishing two semesters of your first year.
  7. Be certified.  Example, SAS offers various options.
  8. Write and present manuscripts at various professional annual meetings.  Net working with others in your area of interests.  A data scientist has to know how to write efficient reports – and most likely the readers may not have rigorous background in stat or math.
  9. Try to teach undergrad classes–this is good training to be a great presenter and a public speaker.  Data scientists need to know how to present their works to others, which usually non-technical users of your findings.
  10. Yes, you need to take 2 semesters qualitative theory, psychometric, survey design and advanced marketing research & consumer behavior courses.
  11. Last, but certainly not the least important, work as hard as you can and avoid or minimize taking student loans 🙂

On Analytics: What Are the Consequences of the Systematic Errors

Now that everyone is talking about analytics.  When the Association introduced the approach for the first-time, different interest groups are rushing—try to take advantage of it.  The software companies are racing to get their first product in the market–try to get the competitive advantage to be the analytics product leader.  In 2013, there was only one institution which offer formal training in data analytics.  Now, there are more institutions offering Business Analytic programs than, may be the applicants.  They are mushrooming every where. This current development is paralleled with the booming of the MBA program back in the 80’s.  The Association glad be able to share and contribute to the development of the curricula not just in the US, but all over the world.

But, the business consideration and profit motive alone is not enough-companies need to educate their users.  Selling analytics is not just another hamburger store–try to sell as many burgers as possible.  It is more than that.  Most of the users think, analytics is just a point-and-click kind of thing which gives amazing results without knowing how the capabilities are structured and built. It is not just something one can produce and visualize, and show the output to their supervisor without knowing what is going on, and how the algorithm works, and what the assumptions are in finding those solutions. Weather the solution is unique or multiple?  In other words, it is not a canned software driven profession–rather the other way around.  The need to solve the real world problems dictates what kind of software needs to be built.  It is not software that derives the needs!  On other account, it is pretty funny that some users think data visualization and data analytics are equivalent.  However, they are not.  For example, an article written about a couple of years ago using the words “data czars“, yet some of them use data visualization and canned programs which is a bit of inflated to portray them as the “czar”.  However, the Association is glad as the innovator–the first entity to promote the application of analytics in higher ed, which then followed by the laggards.  The use of analytics may not exist, limited, unpopular or never been known or applied until after the article was presented and published.  By the way, predictive analytics is just only one component among many of the IRI-Education Analytics.

These are the flaws, facing most of the users who are lack of understanding about the statistical theory or mathematics behind the software.  Most of the analytics, not data visualization, is built, based on the unwritten assumptions in that the Central Limit Theorem is satisfied and that the data are random and the residual terms behave normally plus some other basic assumptions either for univariate or multivariate regression theory.

Sadly, our previous BLOG has mentioned pretty clear that majority of the events are not random, but systematic.  For example, a college administrator may constantly have made sub-optimal decision (in other words, wrong decision) simply because she or he does not apply any historical data to support her of his decision or using the :best guess” or because the past data are generated by the wrong or suboptimal policy.  In such a case we heard what has been mentioned as GIGO-or Garbage In, Garbage Out. If one applies any type of analytics based on tainted data that contained systematic errors, what kind of results will they produce?  Only garbage. A wise man suggests that knowing your data is the first step to use any analytics applications. Test if the events that generate those data satisfy and are consistent with the Central Limit Theorem.

Can a-non decision maker such as Business analytics or IR professionals make a correction or validating the tainted data pulled from Oracle or any database system?  If you are an analytics user, think about it, before getting too excited in applying point-and-click canned program in your cubical 🙂

 

IR Intelligence (Education Analytics): Random and Systematic Errors On The Student Loan Debt

Let us bring our discussions on student loans (SL) to the next level.  There are many sub-system entangled one-to-another that affect the student loans which all the American public has seen these days. If the System is broken, then one needs to know what are the reasons or what factors have caused the problems.  To avoid the unproductive discussions, let us approach this important scholarly work by using the real data with approaches that are academically sound, justifiable and verifiable by who ever that have the interest on one of the gigantic tasks to be solved in the modern history of the USA.  We will apply econometrics and multivariate statistics in these efforts.  To do that, let us bring what the possible relationship among the subsystems may look like Figure 1, as shown below.  Basically, there are four main elements–the US lawmakers, US regulator, the US higher ed institutions and the American public and students.  The first three are endogenous to the system, while the student (American public) sub-system is exogenous.  Therefore, the public sub-system is excluded in Figure 1.  So, none of the students has the ability to shape up the policy directly, but through the representative/lawmakers that they may have voted for, iff (if only if) these lawmakers truly represent them on such an important issue.

  • The lawmakers who have the power to set the general policy has almost a full-control which direction for Uncle Sam to move to, for example NDEA. If things works as planned, this subsystem supposed to operate for the interests of the students or the public as their constituents.  Did they? may be not, read here.
  • The legislator, based on the purpose why this country is established as stated in the Declaration of Independence, is also to work for the people of the country?  Did they?  May be not.  Read here for detail.
  • Higher ed, especially at public universities and colleges are supposed to be managed for the interest of the tax payers.  Did they?  May be not.  Click here.

The overwhelmingly evidences show that none of these subsystems actually directed or managed for the benefit of the American public.  Therefore, the student loans are ballooning.  The real world evidences show that all the errors are non-random, but systematic or Bias E(β)≠β head. 

From the statistical theory, random errors, can always be fixed by adding the observations.  In statistical, mathematical concepts or measurement’s theory, there is no cure for systematic errors.  For example, in industrial engineering (IE) field, if a machine, say B that is used to produce the final product name A, consistently yield an output (product A) that cannot pass the quality control standard, then the factory manager got no choice, but to replace that particular machine (B).  But IE and the system of government is not a comparison apple-to-apple.  So, the readers can find their own answers….

Student Loans And Adam Smith’s On The Theory of Moral Sentiments

The quotes below are taken from the Adam Smith Institute on The Theory of Moral Sentiments, authored by Adam Smith–the Father of Capitalism.

Main themes of the book:

“The Theory Of Moral Sentiments was a real scientific breakthrough. It shows that our moral ideas and actions are a product of our very nature as social creatures. It argues that this social psychology is a better guide to moral action than is reason. It identifies the basic rules of prudence and justice that are needed for society to survive, and explains the additional, beneficent, actions that enable it to flourish.

Self-interest and sympathy. As individuals, we have a natural tendency to look after ourselves. That is merely prudence. And yet as social creatures, explains Smith, we are also endowed with a natural sympathy – today we would say empathy – towards others. When we see others distressed or happy, we feel for them – albeit less strongly. Likewise, others seek our empathy and feel for us. When their feelings are particularly strong, empathy prompts them to restrain their emotions so as to bring them into line with our, less intense reactions. Gradually, as we grow from childhood to adulthood, we each learn what is and is not acceptable to other people. Morality stems from our social nature”

Yesterday, the Association has posted a discussion on student loans, and why moral should be in the equation when decision makers apply a policy which will impact the general public.  Adam Smith which is considered as the Father of Capitalism, as quoted above, in the first paragraph, argued that without considering moral, the society will not survive (Read here how much pain the loans has inflicted the borrowers).  Unfortunately, when more economic schools, both Freshwater or Saltwater are leaning toward “rational expectation” type of approach, then the society may suffer.  The reason has been provided by Adam Smith on the third sentence in the first paragraph.  We are hopeful that all the players of which their decisions may impact student loans have a chance to read this post.

Student borrowers need to be morally responsible in their actions as well.  Taking the loans with a clear purpose, and not for supporting luxury life style or any thing that is less important and unrelated with their degree program.  Rather, to get through college and to graduate on time.  It is often heard the other side of the story, where student borrowers spent their loans for spring break vacations. This is not what the loans meant to be.  Of course, this group of students are the outliers.

Why Do US Higher Ed Institutions Need to Worry About Student Loans Pile Up?

The short answer to the question is because it potentially may negatively affect them, both directly or indirectly.  However, it is difficult to find the honest answer on this question.  Try to think reasons why one needs to visit a dental office periodically?  The answer is not for fun, but to avoid potentially bigger and costly dental treatments in the future.  Therefore, for a better future.  But any person has a free will not to (1). Buy dental insurance; (2). Bought, but never use it; (3). Did not buy any or maybe worse yet (4). Only brush his or her teeth on every other weekend, with the hope nothing is going to happen.  Any institution’s decision makers have the free will.

The challenge to this hypothesis is that anything that deal with the future requires the decision makers to think beyond his own interest.  But, not everyone has that kind of wisdom.  People often think that, in the long-run we all will be dead, so why should they care?  Why should I concern of doing jobs for the larger stake holders’ (students and the public) interests, if the School Board will ax my contract when the time has come?

But, those decision makers who stick with the ideas to serve the public will get their reward, may not be in the short-term, but this genuine idealistic attitude is rare nowadays.  The reason is simple, self-interests and egocentric attitude. A simple example, is how often one finds a motorist is driving at the left lane 50 miles per hour, while the speed limit is 70?.  It is annoying, but the driver just does not have the ethical self-govern attitude.  People cannot think how their attitude could effect others’ in negative ways.  Instead of social or common value used on everyday life, some people used her or his own egocentric value.

The same thing with the student loans.  Accumulation of student loans and rising default rate to a noticeable level may send a discouraging signal to the public in that a college education is expensive, unaffordable and, may be, useless.  If the general public has experienced difficulties to pay their loans, then it may scare other prospects away. This is one of many reasons why some colleges are experiencing enrollment drop.  College decision makers have a moral responsibility to the public, especially at a public entity, in addition to the institutional obligations.  Though, no one can enforce this moral responsibility, it does not mean there is none. It should be in the equation when making public policy that will affect young Americans.  One of my favorite line from the Indiana Jones movie–The Last Crusade is when the Knight says “You have chosen wisely“.

More Discussions on Student Loans Accumulations, Current US Macro Economics Policy and Budget Deficits

Some people may think it is no big deal, when regulator’s spending surpasses its inflows.  Think about your household income.  If ABC family spends more than what they make, somehow they need to cover that excess spending from, say, credit cards.  The same logic applies here in that the credit card company is parallel with buyers of US treasury.  The Fed Chairman, Jerome Powell blamed expensive healthcare delivery system and the aging of our population contributing to such a deficit.  Recently, it was reported the total US national debts is about $21.6 trillion.

One may think that spending has great impacts to the economy, and it does within certain boundaries.  Increasing in aggregate demand has a positive impacts on companies’ revenue from sales.  That makes the stake/stock holders (Wall Street) is happy.  The happiness of Wall Street even higher when the administration cut both the corporate and individual income tax.  These bring huge effects to the DOW (26,743.50 level on September 21, 2018)—the highest since 1929.  So, the economy will expand and unemployment is reduced to the lowest level as well.  In theory, all current macro economics policies will increase the standard of living of many, except those who got trapped with their student loans. In reality, it may not.  Please check if your monthly take home salary has increased this year surpassed the inflation rate, compared to a year ago.

However, if you own, 1 million Amazon’s (AMZN), Alibaba (BABA) or Apple (AAPL) shares, your wealth surely has increased tremendously.  So, you can make your own conclusion where the current economic policies are heading to or directed toward 🙂  But, one needs to be able to have the initial capital/fund/money to buy that 1 million shares at the first place.  We strongly believe that only a handful of US citizen will have that kind of investment money.

Cutting tax while it increases the aggregate demand, it surely will reduce government revenue from tax such that deficits will increase.  However, if the US can increase its export, the build ups may be slower.  Increasing export means winning the competition in the world market. This only happens if the US is able to produce high quality products and  cheaper than other sellers.

The trade skirmish that have been initiated by the administration to many of its trading partners may have lowered the US export.  But, at the same time, it also reduces the US import because of increasing imposed tariffs.  Depending which one is higher, the net effect will have final impact to the budget deficits.

So what did we learn from the discussions above?  It seems that managing the US Colleges and Universities are affected more by the administration’s policy in recent years.  Consequently, education industry is riskier and more challenging to be managed than before. The risk of financial failure does increase, especially to those who relied heavily on government support or aid programs, i.e., Pell Grants, Federal Student Aid, such as Perkins, Stafford, Parent Plus and others.  That is one of the main reasons, why efficiency nowadays, becomes an important vocabulary in managing a higher ed institution.

Scary: The Statistical Correlation Between The US Budget Deficits and Student Loan Build Ups

Interesting enough when one puts together the budget deficits and accumulated student loans side-by-side as shown in Figure 2, then one can start telling an interesting story. Without any formal training in IRI or Education Data Analytics, an individual will notice the two lines persistently are moving toward the same direction, in particular, after 2013.  The existence of a positive correlation between the two lines can be observed through Data Visualization (DV-Figure 2 upper side) or Data Analytics (DA-Figure 2 lower side).  What will be the possible circular and spiral implications of such a relationship?

  1. The American public will not see, at least in the near future that the accumulated student loans will decline, so long the country spending is higher than its fund inflows.
  2. For those who expect to have their loans are forgiven will soon realize that may be far from reality.  Simple reasons, where the government will get the resources to do so?  Especially if budget deficit continues.
  3. Prolong deficits will cause less funding is available from both federal and may be state agencies.
  4. US higher ed institutions will depends on tuition revenue to fund their operation.  That said, tuition will likely to creep up.
  5. Accumulation of student loans will keep going up.
  6. Less and less citizens of the country are able to afford a college education.
  7. College enrollment will be impacted in a negative way.
  8. With less money is available due to reduction on both federal and state funding, alumni’s donation, as well as from the tuition money, will finally force higher ed institutions to cut their research fund.  That will affect the innovation in the future.
  9. College down sizing, merger and closures will likely to continue occurring.
  10. The likelihood of universities and colleges employees lay-off will go up.

These circular and spiral effects will get larger impacts to the whole country. When they do, what will happen to the economy?  Your thoughts?
