Upfront Payment
Key features
Paid at signature of contract Not related to volume of purchases (lump‐sum) Term: slotting allowances
Examples
Grocery stores Drug stores Book stores, record stores
Manufacturer Retailer
Payment before any purchase Payment per unit of purchase
Upfront Payment
To get access to retailers’ (limited) shelf space ‐ just placement on shelves ‐ premium placements (eye‐level shelves, special displays) To have new products introduced in their stores To stay in retailer’s list of potential suppliers
Why do manufacturers (unwillingly) pay slotting fees?
Upfront Payment
If retailers are capable to demand slotting fees, why don’t they ask for lower wholesale prices instead? Why do manufacturers agree (perhaps unwillingly) to pay slotting fees? What is the impact of slotting fees on prices, and how do they affect market structure?
Main issues to address
Literature
R1 R 2 MA
Intra‐brand competition only Miklos‐Thal et al. 2010, Bedre 2009:
- 2. Monopoly prices are sustained
- 1. There always exist CA equilibrium
MA MB R1
Inter‐brand competition only Marx and Shaffer 2008: Caprice and Schlippenbach 2010 (consumer shopping costs):
- 3. Exclusion of less efficient R is always equilibrium
- 4. Prices are still at monopoly levels
- 1. There always exist CA‐SPNE
- 2. No marginal cost pricing
Aim of paper
Question Do we obtain the same results in a situation where oligopolistic competition exists both upstream and downstream?
Set up
MA MB R1 R 2
One link is missing; technical but
R2 delist MA and launch its
- wn‐label imitation
entry of R2 was initiated by MB
provided exclusivity
negotiations between MA and R2
ended in break‐down
Toy R Us Inc. v. FTC (1996)
Remark
No asymmetry of information No shopping costs intra‐brand competition inter‐brand competition inter‐brand competition between
retailers
Key features
Main Findings
1.
In all equilibria firms fail to sustain industry‐wide monopoly profit
2.
Use of slotting fees in equilibrium ‐ MB may use them to dampen intra‐brand competition ‐ MA may use them to compensate for negative impact of sales of its product on total profits from selling product B
3.
There do not always exist equilibria in which retailers carry products of all their respective suppliers

Order of Negotiations
Stage 1 MA and R1 negotiate Stage 2 MB and R1 negotiate Stage 3 MB and R2 negotiate If all negotiations succeeded, then Stage 4 If negotiations in some Mk‐Ri fail, then
MA MB R1 R 2
Each Ri decides on quantities to purchase from Mk Retail competition takes place All payoffs are realized Mk and Ri will never renegotiate

Negotiations start from beginning preserving same order

Second Result
If intensity of inter‐brand rivalry between retailers is sufficently strong, then MA may need to pay R1 a slotting fee. MA MB R1 R 2
MB pays upfront to suppress intra‐brand competition between R1 and R2 MA pays upfront to compensate for negative impact of A

Implication MA and R1 jointly prefer for MB and R2 to set higher wB2
Second Result: Intuition
Implication Exclusion of MA is no longer possible
The effect is stronger,
the stronger A and B compete at R1 and R2 R1 removes only B
MA MB R1 R 2

Third Result
In a framework of sequential contracting, there do not always exist SPNE in which retailers carry the products of all their respective suppliers
Main Result There always exist CA‐SPNE with all links being active
Contrast with literature
Intra‐brand competition only
MB R1 R 2 MA MB R1
Inter‐brand competition only
Third Result: Intuition
a party negotiating with two counterparties cannot fully
appropriate benefits of individual trade with each of them
this effectively increases that partyʹs outside option of
failing some negotiation
this makes it difficult to sustain equilibrium with all
trading links
