The Context
Research Objective
“Disentangle the direct and cross-media effects of four specific outlets on purchase behavior across online and offline channels.”
Data Sources
Econometric Approach
| Variable | Online Effect | Offline Effect | Primary Impact |
|---|---|---|---|
| 0.0628*** | 0.0211* | E-commerce Driver | |
| Catalog | 0.0342** | 0.0573*** | Omnichannel Driver |
| Television | 0.0381** | 0.0707*** | Strong In-Store Driver |
| Radio | 0.0094 (ns) | 0.0152** | Local Store Traffic |
Synergy Observation: Ignoring cross-media effects leads to understating personalized media and overstating mass media impact.
Cognitive Overload
Exposure to too many personalized media types simultaneously (e.g., both Email and Catalog) may reduce effectiveness due to consumer information fatigue.
Channel Priorities
The Role of Catalogs
While often seen as “old school,” catalogs are highly effective omnichannel tools, showing stronger offline impact than email and significant online spillover.
Mass Media’s Role
Television remains a powerful anchor for driving high-volume offline traffic, often serving as a foundation for personalized campaigns.
