  1. Reflections on 3 Cases Scott Swinton AAEA Case Study Workshop, Long Beach, CA, July 27, 2002

  2. RAE Case Publishing(A Brief Commercial Interlude) • Guidelines for RAE Case Studies • How to differentiate RAE from IFAMR? • Types of cases we’d like to see more of: • Public policy (esp. environmental) • Quantitative • Research cases of all stripes • Creative submissions on teaching methods also encouraged

  3. What makes a decision case current & provocative? • Concise writing, brevity • Exhibits in Zeneca vs. Apples • Real people • Engaging, journalistic writing style • Chronological sequence • Ends with decision to be made in the present • Ending of Zeneca vs. Apples

  4. What creates learning opportunities in a decision case? • Incomplete analysis • Leaves room for the enterprising student to make a mark • Contrast analysis process described for Steve (Zeneca) vs. Becky (Apples) • Unresolved outcome  fertile discussion • No “right” answer

  5. Pioneer Argentina IPR • Research case • Presents complete objectives & analysis, rather than withholding as teaching cases often do • Deductive reasoning • Sequence • Introduced problem & identifies research gap • Theory & empirical lit overview • Method: Natural paired comparison single case • Results & discussion (21 of 31 pages) • Conclusions • Bibliography

  6. How does case persuade that its inferences can be extrapolated? • Natural paired comparison: Hybrid corn guards IP; open-pollinated soy does not • Paired IPR regimes: Argentina (weak IPR) vs. USA (strong IPR) • Single firm  Homogeneous management • Thorough lit review • Structured interview method & text analysis

  7. Does IPR case succeed? • At thoughtfully comparing firm-level soy vs corn seed marketing management? • At proving the effect of weak IPRs on corn & soy seed market in Argentina? • At measuring welfare effects of weak IPRs on host country? (primary objective of case)

  8. Zeneca, PLC • Teaching case • Clear focus on brand strategy • Versatile potential for teaching strategy • “Soft” strategy analysis for class discussion • “Hard” quantitative calculation of brand value (e.g., for homework assignment) • Concise & decision-focused

  9. Zeneca (2): Exhibits • Exhibits provide useful detail • Use of exhibits for background detail (Steve’s research into brand value) keeps flow & decision-focus of case undiluted • All exhibits useful & cited

  10. Zeneca (3): Teaching Note • Well structured: • Summary • Teaching objectives • Analysis (incl. numerical calculations) • Supplementary info for teacher (gives semblance of greater expertise) • Concisely written

  11. When Apples Come In • Teaching case • Clear focus; excellent content; innovative integration of statistics into a case • Style didactic & not exciting • Protagonist Becky Lee does all the work

  12. Apples (2): Exhibits • No exhibits (but tables & figures proxy) • Exhibits that might have been: • Quote a statistics text on sample size formula (Did Becky really know it, or did she look it up?) • Apple size distribution data: • Give data on Top Red strain numbers and let students calculate Z-statistics

  13. Apples (3): Teaching Note • Teaching note was included in text • This tips the hand of the teacher • RAE policy now to exclude note from text • Teaching note: What might have been • Intro page opens note (summary, teaching objectives, lit contribution on stat case) • Let students calculate alternative confidence intervals (with last 2 figures given in teaching note, or only parts included in case)

  14. Cases by the numbers
