2. Issues and Data Then (my AMA)
One short-term market of interdependent consumers facing aggregated communications
Now (your AMA)
Multiple markets of linked and interacting consumers and firms over long horizons facing customized communications
Longer-term
Interactivity / Network Effects
Customer-Customer / Network effects
Customer-Firm
Spatial Demand
CRM/Lifetime Value
3. Estimation Then EM/Mixture models
Simulated maximum likelihood
Dynamic programming and control
Stochastic models
Meta-analyses
4. Estimation Now EM/Mixture models
Simulated maximum likelihood
Dynamic programming and control
Stochastic models
Meta-analyses
MCMC/Bayesian
Time series (VAR, DLM, etc.)
Spectral methods
Learning models
Spatial statistics
Empirical I/O models
Non-parametrics
Method of moments
5. 1. Long-term Erosion of Brands
6. Erosion of Brands Customers are more price sensitive.
75% of CPG retailers and manufacturers rank pressure to reduce price as single largest threat in the next 3 years - IRI/EIU Survey
Sales elasticities have increased 1 point in past 25 years (Bijmolt et al. 2005)
7. Erosion of Brands
8. DLM
9. 2. Customer – Customer Interactivity
10. Network Effects Often related in economics and sociology to adoption, pricing, etc.
In marketing many new contexts to study centrality and social influence across individuals as well as populations
Peer-peer networks
Internet chat
Internet auctions
11. New Data
12. New Tools Structural orientation with multiple agents
Auctions
Goal is to infer latent costs of seller and bidder (e.g., opportunity costs of bidding and acquisition costs) and bidder value distribution
Bidders bid if expected return is positive
Sellers list number of items to max profits
Imply bidder and lister likelihoods for MCMC
Can infer effect of fee change when none exists

14. Modeling Network Effects
15. 3. Customer Firm Interactivity
16. Media Proliferation Phil s2Phil s2
17. Interactive, Addressable and Customizable Media
Internet
MSN Ad -- $1MM for 24 hours ($25 K 4 Years Back)
Interactive TV
10MM US HH
Media are now merging
So may the research streams Interactivity
18. E-Customization Approach
19. Modeling Heterogeneity Finite Mixtures Continuous Mixtures
20. Optimization Results
21. 4. Spatial Effects
22. New Issues/Methods Spatial Demand Demand and equilibrium prices used to inform apartment location decision
23. Set Up Moment Conditions
Demand side (location demand errors independent of instruments)
Supply side (price markup errors independent of instruments)
MCMC Estimation (Romeo 2006)
Replace typical MOM e’Z = 0 with e’Z ~ N(0,S)
Allows for Bayesian inference
Spatial correlation in demand and supply errors Estimation
24. Policy Simulation No spatial covariation understates profit variation and leads to parameter bias.
Spatial model yields 65% increase in profits (to $35,010).
25. 5. Customer RelationshipManagement (CRM)
26. CRM Lifecycle Acquisition/Birth
Lifetime Value > Cost of Acquisition
Growth
Cross selling and upselling
Retention/Death/Churn
Predict churn
Loyalty programs
27. CRM Information Sets Many observations and variables
Multiple data sources to merge
Many customers and variables, but incomplete sets
Scalability (e.g., SML v. MCMC)
Rare events
Churn, cross-selling, acquisitions
Inward focused data
28. Internal Data
29. Holdout Sample Performance
30. Rare Events, Many Variables
31. Summary New Issues
Brands in decline, proliferation of media, interactivity, spatial demand, CRM
New Data
Log files, call records, CRM systems
Massive files
New Approaches
Non-parametrics, spatial statistics, EIO
