Entry of Free mobile in France
Mobile market in France in 2011 Q4:• Three incumbent network operators: Orange, SFR & Bouygues Telecom• Highly concentrated: top 3 operators hold 87% market share• No new entry since Bouygues Telecom in 1996
Entry of Free Mobile• Obtained a 3G license in 2009• Entered in January 2012 with low cost voice/large data plan
Incumbents’ reaction: each launched its own low-cost product line:• Orange → Sosh• SFR → Red• Bouygues→ B&You

Fighting brands
Definition• Incumbent’s subsidiary brands targeting the segment entered by low-priced
competitor• Introduced as the incumbent’s strategic response to entry (Johnson & Myatt, 2003)• Distinguished from price discrimination• Intel’s Celeron to fight AMD• Lufthansa’s Germanwings against easyJet & Ryanair
Distinguishing marks of fighting brands• Large scale entry with low-end products• Positioning of fighting brand comparable to entrant’s quality• Without entry, the low quality not supplied by incumbents due to cannibalization

Free mobile’s entry: a fighting brand story?
Free mobile’s entry in 2012• Low prices: unlimited SMS for AC2, unlimited calls & data for AC20• Large scale entry: national coverage with established brand
Incumbents’ reaction• Simultaneously introduced subsidiary brands right before entry• Imitate the price & quality of Free mobile• Under brands sufficiently differentiated from the existing premium products

Research objectives
1. Empirically test the theory of fighting brand in mobile telecom industry• Strategic incentives of the subsidiary brands• Incentives noncooperative or collective?
2. Measure welfare impacts of entry by sources• New product/variety effect: has Free as a low cost operator created large
consumer welfare gains?• Traditional competition effect: did entry reduce the incumbents’ prices?• Indirect competition effect: did entry lead to fighting brand strategy by
incumbents?

1. Fighting brands• Under monopolist incumbent (Johnson & Myatt, 2003)
2. Competition & product variety• Strategic product positioning to deter entry (Berry & Waldfogel, 2001)
3. Impact of market structure in telecom market• Only variety effect on consumer welfare (Economides, Seim & Viard, 2008)• On price & investment (Genakos, Valletti & Verboven, 2017)

Wholesale & retail profits
Total profit of MNO f ∈ F :
Πf =∑l∈Lf
(pl − cl)sl (p)M + (wf0 − cf0 )sf0 (p)M,
and total profit of affiliated MVNO f0:
Πf0 = (pf0 − wf0 )sf0 (p)M.
Two-stage pricing game
1. MNOs set the wholesale price for their affiliated MVNOs.
2. MNOs & MVNOs set retail price.

Incentives for unilateral deviation from the Nash equilibrium,aggregated across all 20 regions during 2011-2014.
Unilateral introduction of FB raises variable profits by more in the absence of entry thanin the presence of entry.
⇒ No increased unilateral profit incentives for FB after entry
⇒ No level of fixed costs can rationalize why FBs were introduced after entry

Profit changes during 2011–2014 in euros
Joint introduction of FB raises variable profits by more in the presence than in theabsence of entry.
⇒ Increased joint profit incentives for FB after entry
⇒ Fixed costs can rationalize why FB introduced after but not before entry.
⇒ Semi-conclusion: incumbents do not invest in low-cost brands, until entry of Freeforces them to do so

Changes in surplus generated by the counterfactual actions labeled in thecolumn. It is measured by subtracting the counterfactual surplus from thevalue in the observed market. The figures are measured in million euros forall 20 regions during 2011-2014.
• Most of consumer gains due to variety effect• Additional consumer gains from incumbent’s prices and FB response• Total welfare gains from variety and FB effects

Conclusions
Fighting brands• More evidence for partial coordination
Welfare gains from entry• Mainly from new product/variety of cost efficient entrant• Additional gains from traditional price competition effect• Extra indirect gains from fighting brands
Future research• Study how entry affects investment
