What You (Really) Need to Know--Decision Science

From former Harvard President and U.S. Treasury Secretary Larry Summers in the NY Times on coming changes in higher education:

"It is not possible to make judgments about one’s own medical care without some understanding of probability, and certainly the financial crisis speaks to the consequences of the failure to appreciate “black swan events” and their significance. In an earlier era, when many people were involved in surveying land, it made sense to require that almost every student entering a top college know something of trigonometry. Today, a basic grounding in probability statistics and decision analysis makes far more sense."

 As a decision analysis professional and teacher, that's good to see.

MBA Math Workshop at Forté Chicago Event June 18

For the third year, I'll be teaching a morning quantitative skills workshop at the Forté Foundation MBA Women's Conference, held this time in Chicago on Friday, June 18. Students admitted to Forté Sponsor schools are welcome to attend.

Here's a workshop description:

This two-hour workshop will build on the pre-work coverage of finance and accounting basics to develop insight into the ongoing credit market crisis. Rather than do a broad but shallow survey of quant skills needed in the MBA first year, I've picked a few tools and a relevant topic from the current business press. We'll dig into the basics of bond valuation and balance sheet leverage with two goals in mind:

  1. Whet your appetite for your upcoming MBA coursework
  2. Provide a status check on your quantitative proficiency.

To learn more about the broader conference, visit the Forté conference site. As of this posting, the site has information about last year's event. Information about this year's event will appear as the event planning comes together. If this link becomes obsolete, then you can start at the Forté events page.

To learn more about the workshop or to take a look at the pre-work material on finance and accounting as an example of the MBA Math lecture material, visit the MBA Math workshop site.

Fear the Boom and Bust

This video is just incredibly creative and educational, highlighting different approaches of the economists John Maynard Keynes and F.A. Hayek to managing the economy. 

I've devoted years to teaching and designing learning materials.  If you come to my classroom or online course motivated to learn then I can help you.  But creating the motivation?  I don't focus on that because it's already there for my students. 

The brilliance of this video is that it has the capacity to generate the motivation to learn about economics in a very broad, and potentially young, general audience.  I hope that the video's creators John Papola and Prof. Russ Roberts do more.

Monday MBA Math: Normal Distribution

The Monday MBA Math series helps prospective MBA students to self assess their proficiency with the quantitative building blocks of the MBA first year curriculum.

The normal distribution is essentially the familiar symmetrical bell curve that characterizes many phenomena.  Even when distributions of interest are asymmetrical, the normal distribution is central to sampling and confidence intervals that help guide efforts to make sense of massive data sets by working with representative data samples.  Working with the normal distribution highlights the importance of thinking about intervals measured by units of standard deviations away from the mean.

Hal Varian, Chief Economist at Google, was recently quoted in the New York Times from a McKinsey Quarterly interview as saying "that the sexy job in the next 10 years will be statisticians."  Perhaps more on point for MBAs, Tom Davenport and Jeanne Harris are releasing "Analytics at Work: Smarter Decisions, Better Results" this month as a follow up to their influential 2007 book Competing on Analytics.  Understanding normal distributions is a core skill in developing the statistical numeracy required to apply analytics to strategy.

Exercise:

Suppose the daily customer volume at a call center has a normal distribution with mean 4,600 and standard deviation 950. What is the probability that the call center will get fewer than 3,400 calls in a day?

Monday MBA Math: Supply and Demand

The Monday MBA Math series helps prospective MBA students to self assess their proficiency with the quantitative building blocks of the MBA first year curriculum.

The market interaction of supply and demand is one of the classic business concepts that people encounter from school snack swaps to shopping at the mall, from start ups to too-big-too-fail banks, and from subprime real estate to U.S. Treasury bond auctions.

The concepts can be used qualitatively and quantitatively.   Like much in economics, supply and demand can be introduced equivalently in pictures or with equations. 

Here, we use equations for a situation involving a perishable agricultural commodity market.

Exercise:

Assume that the demand curve D(p) given below is the market demand for apples:

Q = D(p) = 270 - 15p, p > 0

Let the market supply of apples by given by:

Q = S(p) = 42 + 15p, p > 0

where p is the price (in dollars) and Q is the quantity. The functions D(p) and S(p) give the number of bushels (in thousands) demanded and supplied.

What is the consumer surplus at the equilibrium price and quantity?

Monday MBA Math: Journal and T-Accounts

The Monday MBA Math series helps prospective MBA students to self assess their proficiency with the quantitative building blocks of the MBA first year curriculum.

The first MBA Math accounting exercise explained that balance sheets provide a snapshot of a firm's financial condition at a moment in time, with "balance" referring to the equality between the left side's assets and the right side's combination of liabilities and equity.  The second accounting exercise introduced transactions as the means by which the balance sheet changes over time.  As long as the balance sheet equation (assets = liabilities + equity) is maintained for each transaction then the new balance sheet that results from a large sequence of transactions will remain in balance. 

This exercise introduces journals and t-accounts as recording systems to handle the volume of transactions that companies generate.  Modern accounting recording systems are automated, of course, but putting pencil to paper with journals and t-accounts helps beginning students to internalize the logic of accounting.

Spending time in the accounting trenches working with transactions is critical to developing an informed understanding of the financial statements that MBAs will analyze in their classes and careers. 

Exercise:

Ruston Company
Balance Sheet
As of January 4, 2009
(amounts in thousands)
 
Cash 9,300 Accounts Payable 2,500
Accounts Receivable 5,000 Debt 2,300
Inventory 5,500 Other Liabilities 6,500
Property Plant & Equipment 15,900 Total Liabilities 11,300
Other Assets 1,400 Paid-In Capital 5,700
    Retained Earnings 20,100
    Total Equity 25,800
Total Assets 37,100 Total Liabilities & Equity 37,100

 

Transfer the journal entries to T-accounts for the transactions below, compute closing amounts for the T-accounts, and construct a final balance sheet to answer the question.

Journal amounts in thousands

Date Account and Explanation Debit Credit
Jan 4 Accounts Payable 8  
     Cash   8
  Paid money owed to supplier    
Jan 5 Property, Plant & Equipment 49  
     Cash   49
  Paid cash for machine    
Jan 6 Cash 70  
     Paid-In Capital   70
  Issued stock    
Jan 7 Cash 20  
     Inventory   16
     Retained Earnings   4
  Sold and delivered product to customer    
Jan 8 Cash 51  
     Debt   51
  Borrowed money from bank    
Jan 9 Inventory 14  
     Accounts Payable   14
  Bought manufacturing supplies on credit    
Jan 10 Cash 10  
     Accounts Receivable   10
  Received customer payment    

 

What is the final amount in Total Assets?
