Application of Managerial Overconfidence

Capital budgeting errors:

  1. Ease of processing…
  1. Loss aversion…
  1. Affect…

Specifically, we consider

  1. the still wide-spread use of (patently inferior) payback as a project selection technique,
  2. the tendency to throw good money after bad (sunk costs),
  3. and the proclivity to allow irrelevant information to influence project adoption.

Conduct NPV, IRR and payback period

Capital budgeting and ease of processing

Latter two may be easier to process and more salient. For this reason, they may be compelling.

Capital Budgeting

Allowing Sunk Costs to Influence the Abandonment Decision

Capital budgeting and loss aversion

Say prior investment has not gone well.

Economic impact of ending the lockheed project would be too much

Allowing Affect to Influence Choices

Is it possible that emotion impacts capital budgeting decisions?

Since emotion plays a role in so many other realms, financial and otherwise, it would not be surprising to see it wield influence here. Direct evidence is likely to be anecdotal at best, since it is not clear how to calibrate a manager’s emotional state.

Academic Example

Kida, Moreno, and Smith (2001) surveyed a total of 114 managers (or individuals with similar responsibilities).

For example, in scenario 1, participants were told that they were divisional managers deciding between two product investments, each of which would require working with a different sister division run by two different managers.

Managerial Overconfidence

Ben-David, Graham, and Harvey (2007) found that managers tended to predict stronger performance for their operations than actually occurred. Excessive optimism in project cost forecasts is endemic. When CFOs predict market movements, only 40% of realisations fall within 80% confidence intervals.

There are two forces here. First, generous executive compensation (often only weakly related to firm performance) signals success. Greater overconfidence can result because of associated self-attribution bias. Second, the tendency for boards to be overly deferential and for investors to employ the “Wall Street rule” (sell if unhappy with management) also plays to managerial overconfidence.

For example, research indicates that overconfident managers tend to miss earnings targets in voluntary forecasts, and, as a result, display a greater proclivity to manage earnings.

Tendencies of overconfident managers

  1. Overinvestment.
  2. Sensitivity of investment to cashflows is higher
  3. More active in acquiring other companies.
  4. Too quick to start a new business.

Managerial Overconfidence: Overinvestment

Ben-David, Graham, and Harvey conducted a survey

Overconfidence measure – Malmendier and Tate

Managerial Overconfidence: Sensitivity of investment to cashflows is higher

Two traditional explanations for such investment distortions have been put forth.

  1. Free cash flow problem: It has been suggested that the potential misalignment of managerial and shareholder interests induces overinvestment when free cash is available, as managers are keen to empire build and provide themselves perks.
  2. An asymmetric information view purports that the firm’s managers, acting in the best interests of shareholders and noticing that the company’s shares are undervalued, will not issue new shares to undertake investment projects.

In both cases, investment and cash flows will be positively correlated

Managerial mistake stemming from overconfidence: Excess entry

Businesses, especially small ones, fail at an alarmingly high rate.

One possible reason for this is overconfidence.

Measurement for overconfidence

Excess entry: Experimental evidence

Profit=[10/(Nc)](cE) Profit = [10 / (N - c)] * (c – E)

Where:

Excess entry: Experimental evidence cont. ii.

  1. Subjects’ ranks depended on either a random device or skill, where skill was assessed after completion of experiment using either brain teasers or trivia quizzes (involving current events and sports).
  2. Subjects in some experiments (but not all) were told in advance that the experiment depended on skill.
  3. Subjects forecast the number of entrants in each period.
  4. Entry decisions were made in two rounds of 12 periods each, with ranking being skill-based in one round and random in the other.
  5. Market capacity was as follows: c = 2, 4, 6, and 8.

Experimental evidence – Key Issue

Are players more likely to enter when one’s profit is determined by perceived skill?

If people have true picture of their skill relative to the skill of others, there should be no impact:

Can Managerial Overconfidence have a Positive Side?

Conclusion

  1. Because of ease of processing, inappropriate capital budgeting techniques may be favored. Because of loss aversion, managers may throw good money after bad. And because of affect, emotion sometimes gets in the way of optimal managerial decision-making.
  2. There are many markers (measures) of managerial overconfidence. One is the tendency to hold on to in-the-money options too long.
  3. Managerial overconfidence likely leads to various forms of investment distortions or overinvestment.
  4. Aside from too much capital spending, overinvestment manifests itself in tendencies toward excessive M&A activity and to be too quick to undertake start-ups.
  5. An example of an investment distortion is allowing the availability of internal funds to dictate whether investment should go ahead.
  6. Overconfidence may have a bright side, though, in particular because it “corrects” excessive managerial risk aversion.
