MOOC Review: Wharton’s An Introduction to Corporate Finance
I recently completed a four-course sequence from the University of Pennsylvania’s Wharton School which included courses on operations management, marketing, financial accounting, and corporate finance. I’m happy to say the courses were fulfilling and have provided substantial support to my professional career.
I fully expected An Introduction to Corporate Finance, taught by Professor Franklin Allen, to be a challenge. In many ways, MBA-level corporate finance is equivalent to organic chemistry for chemistry and biology majors, dynamics for mechanical engineers, and quantum physics for physics majors. It’s the course that separates students with a firm grasp of foundational material from those who don’t.
That’s not to say that someone who wants to be a marketer isn’t qualified if they don’t ace corporate finance, but anyone who wants to be taken seriously as an elite-level financial analyst must do well in this course and its successors.
Course Overview
This six-week MOOC took participants through the mid-term exam of the on-campus course FNCE 611. There were five problem sets worth a total of 25% of the grade, a business case worth 25%, and a final exam worth 50%. MOOC students had to earn 60% of available points to receive a certificate, based on our best results from three attempts on each problem set, the case, and final. At least, that’s the way things ended up (more on that later).
Each week added skills to our analytical toolbox, starting with determining the object function for corporations, calculating present values, valuing stocks and bonds, using net present value to analyze cash flows, measuring risk, pricing assets, and applying the Capital Asset Pricing Model (CAPM).
I’m familiar with net present value and bond calculations from my work with Excel, but I gained a deeper understanding of the mathematical mechanisms underlying those basic methods from Professor Allen’s explanations. I must admit that I struggle with geometric explanations of indifference curves, production, possibility curves, and other concepts. I knew the course would start with those topics, so I buckled down and did my best with them. The rest of the material came…I won’t say easily, but the insights I gained from that first week helped quite a bit.
Production Notes
One of the alleged benefits of MOOCs is that it allows instructors to move away from the “sage on the stage” paradigm, where the professor lectures from a podium, often with the help of visual aids. In An Introduction to Corporate Finance, Professor Allen allowed the University of Pennsylvania to record his classroom lectures. The reason for this choice is quite simple: his lectures consist of meticulously prepared and explained motivational examples that he works through in detail. I’m not certain how he could have provided the same content without essentially rerecording his lectures in a different format.
As I mentioned earlier, we had to earn 60% of the available points to pass and had multiple, untimed attempts at the weekly assignments, case, and final exam. When the course launched, those terms were 70% or more to pass and a single attempt at each graded activity. I don’t mind admitting that my eyes started crossing and uncrossing when I realized what I expected to be the e-learning equivalent of a harder-than-normal Wednesday New York Times crossword puzzle had turned into a serious academic endeavor. I imagine a significant push-back against these requirements led to their relaxation, but it did water down what might have been a significantly more rigorous test of our abilities.
My commentary might make it sound like Professor Allen is a demanding, unfriendly presenter, but that’s not the case. He adopted a matter-of-fact delivery with an emphasis on clarity, but whenever a student raised a hand or asked a question, he looked at them, smiled, nodded his head, and said “Yes?” His manner indicated the query was welcome because, as he noted in the first lecture, it was likely the questioner wasn’t the only person in the room who needed a point clarified.
He also shone when discussing student life and the history of the Wharton School. In particular, his eyes lit up when discussing the Wharton Olympics, a now-discontinued competition where student teams, each with a faculty participant, ran relay races, threw paper balls into trash cans, and performed other bits of office-related skill in a day that must have been a welcome break from the rigors of the coursework.
I’ve no doubt Professor Allen demands great work from his pupils, but I’m equally certain he wants them to succeed.
Conclusions
Based on my experience in An Introduction to Corporate Finance, I’m not sure I have the skill set and temperament to do this sort of work on a high level. Perhaps I’ve psyched myself out after a poor showing in my undergraduate microeconomics class at Syracuse, but some concepts just haven’t stuck. That’s not to say I didn’t benefit greatly from Professor Allen’s course. I certainly did, and believe I could make a solid run at passing the on-campus version of this class. I’ll go into more depth on why that’s the case in my final, summary post on the Wharton MOOCs.
In the end, An Introduction to Corporate Finance turned out to be a highly challenging and eminently rewarding course. To my knowledge it hasn’t been offered since I took it in Fall/Winter 2013, but I hope it will be soon.
I’ll wrap up my discussion of the Wharton MOOCs with a final post on my overall impressions of the courses and how they represent the school in the online learning milieu.
MOOC Review: Wharton’s An Introduction to Financial Accounting
I recently completed a four-course sequence from the University of Pennsylvania’s Wharton School which included courses on operations management, marketing, financial accounting, and corporate finance. I’m happy to say the courses were fulfilling and have provided substantial support to my professional career.
Course Overview
Professor Brian Bushee note that his goal in creating his course, An Introduction to Financial Accounting, was to give students the ability to understand information provided in company financial statements. Accounting is a complex and at times arcane practice area, but I thought Professor Bushee did a great job of breaking the topics into manageable chunks and providing detailed explanations of each segment.
Bushee starts out with the standard statement that debits go on the left and credits on the right, but of course it’s much more complicated than that. Some accounts have their balances increased by credits, some by debits, and how some intermediate accounts serve as bridges to relieve the tensions inherent in double-entry bookkeeping. As the course progressed, he described the tools accountants use to document corporate operations for managers, financial analysts, and tax authorities. It might not surprise you that these various audiences don’t always desire the same information.
Each week’s lectures ended with a tour of 3M’s annual report, allowing the professor to demonstrate how the document’s contents reflected the accounting practices taught during the week. I thought these segments provided useful context for the material and helped me get a better handle on concepts I didn’t grasp during the initial presentation.
Production Notes
Professor Bushee spent most of his time switching between a “talking head” single shot of the professor and screen grabs of either Excel or PowerPoint, but he also used computer-animated “students” to be the voice of the viewer. He had his virtual students ask questions that were alternatively probing, wondering, insightful, and (occasionally) stupid. At first I thought the virtual students would be hokey and horrible, but they grew on me quickly. Each virtual student had a distinct personality with likes, dislikes, and preferences based on their background. The students ranged from a grumpy old man to a surfer dude to international students from Hong Kong and the U.K., which allowed the professor to address the differences between accounting practices in the U.S. and much of the rest of the world. Their interactions also developed along an internal narrative, which pleased my inner storyteller.
Material was divided into eight main modules, each of which had an associated quiz, plus two exams covering the first and last halves of the class, respectively. We could drop our two lowest quiz scores, which made reaching the passing threshold of 60% much easier. Professor Bushee also offered a certificate “with distinction”, which could be earned by scoring over 90%. I appreciated the possibility of earning a more prestigious credential, but I fell just short of that mark.
I laughed a bit to myself when the professor said that the material on the time value of money would be the hardest because it involved math beyond addition and subtraction. I actually found this material to be the easiest to grasp, both because of my extensive use of Excel and relative unfamiliarity with accounting principles. Accounting is a formal language that is no doubt comfortable to individuals who have spent their adult lives mastering it, but I felt safest when able to retreat to my NPV formulas.
Final Thoughts
Professor Bushee is, like his colleagues who taught the other Coursera MOOCs, an engaging presenter. He also revealed some details about the production process in his 20-minute goodbye video and posted detailed statistics about the course participants’ demographics and engagement levels. I think this kind of information adds substantial value to students who complete a MOOC. Knowing that I was part of the 6% of students who signed up for the course to successfully complete it is worth almost as much as the certificate.
I just finished An Introduction to Financial Accounting, so Wharton hasn’t had the opportunity to offer it again as of this writing. Professor Bushee indicated that he planned to rerun the course in the future, so it should be available to anyone looking to improve their financial knowledge and gain a better understanding of the accounting practices that help us document our businesses.
MOOC Review: Wharton’s An Introduction to Operations Management
An Introduction to Operations Management
I’m lucky that MOOCs (massive open online courses) came along when they did. I’ve had the opportunity to sample content from a wide variety of institutions and topics either for free or, if I wanted to receive a slightly spiffier “signature track” (from Coursera) or “identity verified” (from edX) certificate, a small fee.
I recently completed a four-course sequence from the University of Pennsylvania’s Wharton School which included courses on operations management, marketing, financial accounting, and corporate finance. I’m happy to say the courses were fulfilling and have provided substantial support to my professional career.
Course Overview
I started the sequence by taking Professor Christian Terwiesch’s course An Introduction to Operations Management. This course combined analytical techniques from operations research and process management, with specific movies showing students how to identify bottlenecks, evaluate the effects of potential changes to a process, estimate customer wait time, and build production errors and rework loops into our process models.
Terwiesch starts out each module with a conceptual overview of the topics to be covered before moving to detailed analysis in Microsoft Excel. I spend many hours in Excel for my writing and online course development projects, so I had no trouble following him as he worked through the formulas. I assume students of an MBA-level course, even one offered for free, will bring some spreadsheet skills to the table, so I believe anyone approaching the course in a serious manner could follow along easily.
I haven’t seen a syllabus for the full intro to operations management course at Wharton, but the professor noted that he covered about 60% of the material in his book (co-authored with G. P. Cachon) Matching Supply with Demand: An Introduction to Operations Management. The most recent (third) edition runs at least $96 used from Amazon, but the publisher created a custom ebook students could buy for $30. I purchased a previous edition of the book for reference, but I got along just fine with the free materials provided through Coursera.
Production Notes
This course is offered in the MOOC-standard format of switching between a “talking head” single shot of the professor and screen grabs of either Excel or PowerPoint. Professor Terwiesch is an engaging speaker who has tremendous command of this course’s material, so he was able to cover the topics efficiently while explaining concepts and applications clearly.
Material was divided into five main modules, each of which had an associated homework assignment, and a comprehensive final. Each homework was worth 10% (with essentially unlimited attempts) and the final exam 50% (two attempts allowed). The passing threshold was set at 50%, which I thought was too low. It’s hard to strike a balance between enticing students to stay and challenging those who do, but for future sessions the professor might consider raising the bar to 60% so even a student who misses a homework would have to score at least 20% on the final to earn a certificate.
Final Thoughts
As with the other Wharton courses I took through Coursera, I found An Introduction to Operations Management to be engaging and interesting. Professor Terwiesch is a solid presenter who comes across well. Even though his production values didn’t extend beyond good video and audio quality, he held my attention with well-executed movies of appropriate length for each topic.
Wharton has re-run this course through Coursera at least once since I took it, though future sessions haven’t been announced as of this writing. If you work in a manufacturing or customer service-oriented firm where knowing the heartbeat of your operations would help you improve your business, or if you’d like to sample Wharton’s MBA courses, I highly recommend taking An Introduction to Operations Management.
Perceived safety increases risk-taking
In many senses, life is a series of risk/reward calculations. Choosing which school to attend, buying a house, and choosing a spouse are all risky endeavors. According to the Peltzman effect, also known as risk compensation, people have a tendency to take greater risks when perceived safety increases.
I’m sure this conclusion comes as no surprise to you. Toddlers learning to walk soon start to run, or go down stairs, with the expected results. Teen drivers (particularly teen boys) get comfortable behind the wheel and dart off in a burst of testosterone, occasionally ending up in dire circumstances. This phenomenon was very common the Formula 2 racing series. Formula 2 is a development series for the global F1 competition, which is viewed as the pinnacle of motor racing. The problem is that the Formula 2 series was plagued with multiple accidents resulting from brash moves made by the young drivers. The reason? Analysts, including current F1 drivers, argued that Formula 2 racers were overly aggressive because their cars are so safe. Romain Grosjean, a Formula 2 driver who now competes for the Renault F1 team, was fined several times and sat out for an F1 race after being at fault in repeated incidents following his promotion.
Investors make similar risk/reward calculations. Wall Street investment bankers often take significant risks because their compensation schemes reward short-term success far more than they punish failure. Why would they take such risks? Because it’s part of their overall strategy. In the Wharton School’s corporate finance MOOC I’m taking on Coursera, Professor Franklin Allen argues that one’s sense of risk is inverted when you think of investing in a portfolio of stocks rather than in a single stock. For example, imagine that you buy stock in an oil company that finds oil in 1 out of 20 wells, and each producing well returns $100. You have a hit rate of 5% which, multiplied by the return of a good well, yields an expected value of $5. Now imagine that you have a separate investment in a research company that has a 1 in 50 chance of returning $250, otherwise gaining you nothing. This investment has a similar expected value to the previous example, because 2% (1 in 50) of $250 is $5.
Which of the two investments is less risky? If you look at the expected values, they’re equally risky. However, Professor Allen argues that, when considered as part of a portfolio, the latter investment is less risky because of its higher potential return. The crux of the argument is that a diversified portfolio with numerous independent risks will tend to have a higher return than a collection of pedestrian investments with relatively low risk. The end result is safety in numbers. Just as a fair coin flipped 1,000 times will tend to show heads in about 50% of the trials, investments with independent risks will tend to earn out at their expected rate, assuming you adjudged the risks correctly in the first place. Statistics on investment return since the year 1900 bear out his argument.
Improvisers can and should take risks to make great scenes. We can do it without fear because we know our fellow players will be there to make what we say and do the right thing. Similarly, businesses can take risks as part of a diversified portfolio of ideas. Just as you wouldn’t invest in a single stock such as, I don’t know…Enron, you shouldn’t discourage experimentation and risk. That said, you must understand that risks taken within a scene or business are dependent, not independent. There’s only so much we can do to fix things if you go too far overboard. If you can’t spread out your risk, you must moderate it to be successful.
A Playful Attitude Makes Life Easier
News flash: life ain’t easy. I used to hear that being an adult wasn’t easy, but with the piles of homework and outside activities heaped on kids these days it’s fair to apply the statement to everyone. George Carlin opined that every kid’s daily schedule should include a couple of hours staring out the window — I think that’s a terrific idea.
Having time to yourself gives you the freedom to think about whatever comes to mind and combine ideas in new ways. In other words, to play. This attitude can become a habit, letting you see the unconventional and humorous sides of issues even though you take them seriously.
I discovered a terrific example of this approach in the description of the Wharton School of Economics’s course An Introduction to Operations Management on Coursera.org. The FAQ list contains this bit of whimsy:
What is the coolest thing I’ll learn if I take this class?
You will look at the world with different eyes – you will start to detect bottlenecks, identify productivity wastes, and come up with ideas to improve business processes. A known side effect of these skills is that you might drive friends, family, or co-workers crazy when you point to their improvement opportunities…
The descriptions for the other three Wharton classes contain similar humorous elements. This approach should appeal to casual learners the Wharton School wants to engage with (it certainly caught my attention) and makes the prospect of taking a MOOC offered by a prestigious MBA program a little less imposing. I like their thinking and can’t wait to get started.
