3. What’s the Difference? Durable investments in complementary assets
Hardware
Software
Wetware
Supplier wants to lock-in customer
Customer wants to avoid lock-in
Basic principle: Look ahead and reason back Kierkegaaard: “it is perfectly true, as philosophers say, that life must be understood backwards. But they forget the other proposition, that it must be lived forwards.”
Kierkegaaard: “it is perfectly true, as philosophers say, that life must be understood backwards. But they forget the other proposition, that it must be lived forwards.”
4. Examples Bell Atlantic and AT&T
5ESS digital switch used proprietary operating system
Large switching costs to change switches
Computer Associates
Aircraft repair and cargo conversion Bell Atlantic: 1995 suit for monopolization
15 year life of switch
Computer Associates: $3.5 billion, behind Microsoft and Oracle
Computer Associates: $432,000 per employee
Microsoft: $422,000 per employee
Oracle: $180,000 per employee
Don’t want to switch OS or applications or vendors.
Peru bought Soviet aircraft at deep discounts
Didn’t buy manuals or spare parts!

5. Small Switching Costs Matter Phone number portability
Email addresses
Hotmail (advertising, portability)
ACM, CalTech
Look at lockin costs on a per customer basis
6. Valuing an Installed Base Customer C switches from A to "same position" w/ B
Total switching costs = customer costs + B's costs
Example
Switching ISPs costs customer $50 new ISP $25
New ISP make $100 on customer, switch
New ISP makes $70 on customer, no switch
Disruption costs
Example: ILECs v CLECs
Competitive market
Profit=switching costs
e.g. ILEC profits=customer + CLEC switching costs
7. Profits & Switching CostsIn General: Profits from a customer = total switching costs + quality/cost advantages
In commodity market like telephony, profit per customer = total switching costs per customer
Use of this rule of thumb
How much to invest to get locked-in base
Evaluate a target acquisition (e.g., Hotmail)
Product and design decisions that affect switching costs
8. Classification of Lock-In Durable purchases and replacement: declines with time
Brand-specific training: rises with time
Information and data: rises with time
Specialized suppliers: may rise
Search costs: learn about alternatives
Loyalty programs: rebuild cumulative usage
Contractual commitments: damages
9. Durable Purchases Aftermarket sales (supplies, maintenance)
Depends on (true) depreciation
Usually fall with time
Watch out for multiple pieces of hardware
Supplier will want to stagger vintages
Contract renewal
Technology lock-in v. vendor lock-in
10. Brand-specific Training How much is transferable?
Software
Competitors want to lower switching costs
Borland and Quattro Pro help
Word and WordPerfect help Wordperfect help in Microsoft WorldWordperfect help in Microsoft World
11. Information & Databases Datafiles
Insist on standard formats
12. Specialized Suppliers Advertising, legal, accounting firms
Pentagon
Dual sourcing
Intel and AMD
Adobe PostScript
Java
13. Search Costs Transactions cost in finding new supplier
Also costs borne by new supplier
Promotion, clsoing deal, setting up account, credit risks
Example: Credit Cards
$100 million in receivables sells or about $120 million
Market valuation of “loyalty”
14. Loyalty Programs Constructed by firm
Frequent flyer programs
Frequent coffee programs
Personalized Pricing
Gold status
Example: Amazon and Barnes and Noble
Amazon Assocates Program v. B&N's Affiliates program
Add nonlinearity?
15. Contractual Commitments “Requirements contract”: Purchase supplies from one supplier
Beware of “evergreen contracts”
16. Suppliers and partners Railroad spur lines
Customized software
17. Follow the Lock-in cycle Selects brand: comparison
Sampling phase: try the product
Entrenchment: makes the durable investments
Lock-in: costly to changeSelects brand: comparison
Sampling phase: try the product
Entrenchment: makes the durable investments
Lock-in: costly to change
18. Lessons Switching costs are ubiquitous
Customers may be vulnerable
Value your installed base
Watch for durable purchases
Be able to identify 7-types of lock-in
