Some thoughts on accounting education ...

I often teach MBA students who have had (traditional) courses in accounting before taking a somewhat more advanced course in an MBA program.  I can tell from my many interactions with tudents that their basic thought coming into the course is, Oooooh Yeeeeaaagghh, I've had accounting before so this course will be an easy A!  It turns out that this thought seems to be what prevents them from earning a relatively easy A in a much more thought-provoking course in accounting than they are used to.  In fact, I've had a number of students who were actually furious: "You aren't teaching accounting they way I learned it before!"  There's a very good reason for this; let me explain.

Many who have taken traditional accounting courses are led to believe that learning how to do accounting—that is, learning accounting methods—is the same thing as understanding accounting.  This is, unfortunately, not true.  In accounting and related disciplines there are concepts, principles, and methods.  Concepts are things that can be defined.  Principles are fundamental relationships between concepts.  Methods are ways of applying concepts and principles to the relevant domain of the concepts and principles (e.g., accounting methods are ways of applying accounting concepts and accounting principles to economic events).  The relationship among concepts, principles, and methods suggests that an understanding of methods alone is far from adequate; concepts and principles must be understood before the methods can even be developed.  The courses I teach in financial accounting tend to be designed to focus on accounting concepts and principles for precisely this reason.

Learning “how to do accounting” means learning how accounting methods are applied to economic events.  Given the limited time available in any course, this means learning how to apply accounting methods to a relatively small set of economic events.  The educational theory presumably underlying such traditional courses is that students will learn accounting concepts and accounting principles by inference while studying accounting methods.  Unfortunately, experience in the U.S. has shown that neither future accountants nor managers generally understand accounting concepts and principles adequately; they need "real world experience" with accounting to understand it.  Moreover, given the current development of computerized accounting systems, it is generally unnecessary for managers to understand much in the way of accounting mechanics at all: Substantially all accounting mechanics are automated via software in any modern computerized accounting system, and such software is written by IS programmers based directly on accounting concepts and principles.  (Many readers will no doubt disagree with this statement, but I can clearly show that accounting mechanics/methods flow directly from more basic concepts and principles.  Trust me on this for the time being.)

What does it mean to say that accountants or managers do not understand basic accounting concepts and principles? The question is best answered indirectly through an example. Ask any accountant the following question:

If my company pays $100 cash for an ordinary pen that can easily be purchased for $1 at any office supply shop in the area, how should my company record the exchange?  

Most accountants will simply answer the question by saying the acquired pen should be recorded at the amount paid for it.  When asked why the exchange should be recorded in this way, most accountants answer that it is a simple application of the historical cost principle.  It turns out that neither answer is correct:  The proper accounting measurement of the pen depends on certain economic characteristics of the exchange and of the buyer and seller, and the “historical cost principle” actually does not suggest the pen be measured at $100 for accounting purposes.  So, the accountant (or manager) knows how to record the exchange given that the measurement is correct, but actually does not know how to determine the proper measurement.  This is but one simple example of how understanding accounting mechanics—so-called, “debits and credits”—does not provide accountants or managers with an adequate understanding of accounting concepts and principles, which is in fact a necessary prerequisite for understanding accounting methods in general.

I realize the argument is somewhat skeletal, but I will fill in the details later!

So you want to pass the CPA examination ...


... the easy way.  After all, who wants to pass it the hard way, eh?  When I was finishing my undergraduate degree in accounting at Indiana University, I was quite apprehensive about the CPA exam.  Several of my friends were a year ahead of me and, although they were pretty much straight-A/A- types, they had horror stories about how hard and how long the CPA exam was.  So, not being the straight-A type I decided to postpone writing the CPA exam until I got out of school and had plenty of time to study.  Everyone told me this was a Bad Idea: "You'll forget everything you studied in school and the CPA exam is a textbook exam."  Nonetheless I waited ...

On my first job as an auditor I traveled pretty much all over the US (except for Las Vegas and Salt Lake City ... my employer wanted us to avoid the extremes, I suppose) and traveled a lot; I was gone 39 weeks in my first year.  Because I didn't want to watch TV at night in the hotel, I decided I would take the Becker CPA Review course and be productive instead.  This didn't work well at all.  First, I almost killed myself and other drivers trying to get from the client to where the course was meeting at some unknown strip mall in New Jersey (for example) by the 7:30pm start time.  Then, I immediately noticed the course went far too quickly through things I didn't understand and far too slowly through things I did.  Finally, there was the problem of spending, as I recall, six hours on Saturday back in Chicago studying accounting in the same fast/slow way after an exhausting week in Great Bend, Kansas (my boss, Keith, was there to "help" and pour beer over my head at the restaurant that week).

So, I quickly dropped the Becker course, got about a 75% refund of the course fee, and decided to use Gleim CPA Review instead.  Being the obedient quasi-Catholic accountant I am, I followed the studying recommendations of Gleim religiously ... for about a month and a half.  Then after a several month study sabbatical, I recommenced my studies two weeks before the exam.  Perhaps no one in the world was more shocked than I when I got my exam scores indicating I passed all parts of the exam except Business Law (the only thing I hadn't studied at all).  Needless to say, this stunning turn of events after all my straight-A friends had said the CPA exam was so hard made me think: Why was the exam easy for me?

Being the social scientist and educational psychologist I am, I spoke with my friends quite a bit about their CPA experiences and delved in to how they studied and understood accounting.  After a series of conversations with my friends and other accountants, and after much reflection and introspection, I realized there was only one possible explanation for why the CPA exam had been so easy for me and so difficult for others:  I had never been taught or burdened with The Great Anachronism of Accounting Education, the "T account".  Instead I had learned accounting when I was 16 from my first instructor at Indiana University, Jamie Pratt, as applied algebra; and I had always put financial accounting into an algebraic structure ever after.

Because eschewing "T accounts" is nigh on blasphemy in accounting, I will not try to sway the Esteemed Reader with rhetoric but will resort instead to the Socratic Method to make my point.  Consider the following problem adapted from a prior year CPA exam problem published in Wiley's CPA Exam Review; a fairly common type of problem that tests whether one understands basic accounting concepts and relationships among the concepts, and can apply the understanding in solving an accounting problem:
PROBLEM
Accounting data:
Accounts receivable--gross ........ $1,000 (1/1/09) and $2,000 (12/31/09)
Allowance for uncollectible accts ..... $100 (1/1/09) and $300 (12/31/09)
Cash receipts on receivables .............. $27,000 (year ended 12/31/09)
Uncollectible customer accounts written-off .................... unknown
Sales revenues .................... $30,000 (for the year ended 12/31/09)
Given the above, determine the accounting entry to recognize uncollectible accounts expense for the year ended 12/31/2009.
There, of course, is no unique way of solving the problem; I can think of at least three ways.  But there is one really fast, easy way to solve the problem.  To make things more interesting and suspenseful-, nd because the Socratic Method kind of requires one to actually think about the problem without being presented with the solution, DO NOT LOOK AT THE SOLUTION BELOW BEFORE YOU CONSIDER THE "T-account" METHOD OF SOLVING THE PROBLEM.

Step 1: Determine how net accounts receivable change over time ...



Step 2: Substitute the data into the equation and solve for the unknown ...


I've watched many students who understood the algebraic approach, and those who didn't (those who used the "T-account" method), solve this type of problem.  The algebraic approach usually gets to a correct solution in less than five minutes with no problems; the T-account method usually takes 10-15 minutes and usually requires rework due to "problems with pluses and minuses".  But I'll let the reader be the judge as to which method is best!  MMc

The case for pirates ...

... is an interesting, preliminary digression from the main purpose of the site.   Consider the relationship between average global temperatures and the number of pirates roaming the high seas.  I first became aware of the relationship while reading www.venganza.org (a, no doubt, respectable website!) and then did my own econometric analysis on the data published there; the results of which include the following graph:

Those interested in econometric methods might be interested in the following equation estimated using OLS:

So, what does it all mean?  Let's just say the results are consistent with the following hypotheses:
  • There is generally a negative relationship between pirates and average global temperatures (GT); as active pirate counts increase, GT begins increasing again. decreases until there are approximately 36,000 active pirates, after which
  • The optimal number of active pirates on our high seas is approximately 36,000 in the sense that GT reaches its minimum at that level.
I know:  It's also consistent with all kind of other hypotheses as well (e.g., like I've misapplied econometric methods and violated the Gauss-Markhov Theorem, which is true).  But it really is not completely unreasonable that pirates (and for that matter, terrorists and terrorism) reduce average global temperature:  Maybe pirates make oil super-tanker shipping more dangerous, costly, and slower, thus reducing oil consumption ... .  You get the idea.

But now we come to the main point:  We'll likely never know whether pirates are good or not for global warming.  We can only estimate these things, and our ability to estimate them depends on understanding econometric theory and methods adequately and--quite as importantly--our theory of the causal relationships between global temperatures, pirates, and all the other important causal factors influencing them.  The same is true about relationships between, say, equity prices and financial statement data.  So ... Rock on Econometrics!

Accounting, econometrics, and ... philosophy?

It's always best to start anything by considering one's philosophy. A lot of how and why I think what I think originates from my philosophy, which happily can be captured in a relatively small number of quotes. (I've never had a truly original thought in my life.) I actually read these quotes fairly often as a means of structuring my thinking, so--however strange it might seem for a site about accounting--this will give you a good idea of where the ideas come from at a basic level:

Quotes to live by (read daily for best effect) ...

“Life's but a walking shadow, a poor player that struts and frets his hour upon the stage, and then is heard no more: It is a tale told by an idiot, full of sound and fury, signifying nothing.”   
William Shakespeare (from "Macbeth")

“… I just cannot bear to be shut in. My endeavor shall be, in such future as stretches out its snowy and lilywhite arms to me before the nozh overtakes or the blood spatters out its final chorus in twisted metal and smashed glass on the highroad, to not get loveted again.”  Anthony Burgess (from "A Clockwork Orange")

" … I must despise the world for not perceiving that music is a higher revelation than any wisdom or philosophy … God is nearer to me than to others. I approach Him without fear, I have always known Him. Neither am I anxious about my music, which no adverse fate can overtake, and which will free him who understands it from the misery which afflicts others."
Ludwig von Beethoven

"Happiness is neither virtue nor pleasure, nor this thing nor that, but simply growth. We are happy when we are growing."  William Butler Yeats

"Who does nothing, makes no mistakes; who makes no mistakes, learns nothing."
Luca Pacioli

“Is't right, I ask, is't even prudence, to bore thyself and bore the students?”
Goethe (from “Faust”)

"From my childhood I lived in a world of books, and since I was taught by their help I could gain clear and assured knowledge of everything useful in life, I was eager to learn from them."  Rene Descartes

"Most people would rather die than think: many do."  Bertrand Russell

"Let us be up and doing with a heart for any fate, still achieving, still pursuing, learn to labor and to wait."  Henry Wadsworth Longfellow

Quotes to research by (read in order for best effect) ...

"It is theory that decides what can be observed."  Albert Einstein

"If you want literal realism, look at the world around you; if you want understanding, look at theories."  R. Dorfman

"Logic merely sanctions conquests of the intuition."  J. Hadamard

" … for intuition, unsupported by logic, habitually assumes that everything is much nicer behaved than it really is."  Ian Stewart

"What are called the operations of the mind are merely the operations of language … . "
John Horne Tooke

"If we spoke a different language, we would perceive a different world."
Ludwig Wittgenstein

"The limits of my language are the limits of my mind. All I know is what I have words for."
Ludwig Wittgenstein

"At a more advanced level, we have such tools as the equation or formula which enable [us] to learn in a few hours fundamental and pervasive features of the behavior of things which [we] could otherwise learn only imperfectly with great labor or not at all."  E. L. Thorndike

“It has been my experience that competency in mathematics, both in numerical manipulations and in understanding its conceptual foundations, enhances a person's ability to handle the more ambiguous and qualitative relationships that dominate our day-to-day financial decision-making.”  Alan Greenspan

"Mathematics … [is] a mirror, an incredibly pure mirror, of the relations that link the facts of our existence."  K. Knopp
"In science, what can be proved should not be believed without proof."  R. Dedekind

And a fascinating quote from a research colloquium ...

“We won’t solve this problem with theory, we need intuition and logic.”  Anonymous

That last one is a bit like “We don’t need a flashlight, we need batteries and a small light bulb.” don’t you think? :)
