I makes commercal sense o use he smar hones as anoher laform for adversng. Many surveys redc bllons of dollars n revenues for moble adversng. One of he key benefs of moble adversng s he ably o be n he momen and o connec wh consumers wherever hey are locaed. Imagne ha you no only have he ably o reach consumers wherever hey are, bu now you can also undersand her surroundngs. Cone awareness echnology, based on he clues from a consumer's surroundngs, can hel you delver your message o your arge cusomers n a much more ersonalzed and valuable way. Mobly and LBS combned wh cone aware adversng creaes oorunes for argeed markeng and revenue generaon. LBS are a class of comuer rogram servces, ncludng he secfc locaon and me daa as conrol feaures n comuer rograms, whch s accessble wh moble devces and whch uses nformaon on he geograhcal oson of he moble devce. Ths servce has become more and more moran as he growh of he marke of smar hones and ables. LBS are used n a varey of suaons, such as adversng, eneranmen, healh, ndoor obec search, ec. 1
There are many moble adversng laforms n he marke, such as AdMob, AD, InMob, Facebook, and Von ec. Through hese laforms, he alcaon develoers can easly add adversng elemens no as and share adversng revenue. The adversers can adverse n-a ads whn he alcaons. Comared wh radonal dslay ads, hs form of adversng more emhasze on audo, vdeo, and s desgned accordng o he characerscs of moble devces. The user can enoy he neracve adversng ourney. Wh LBS, hese laforms can rovde moble ads whch are hghly relevan o he user s locaon. The adversers can rovde he sore s nformaon, adverse n he assgned locaons and realze onlne o offlne. For eamle, Aud use InMob s locaon-enabled ads n Jaan o arac consumers o local car dealers ha delver ersonalzed ads o moble consumers wh GPS locang caables. The GPS locaor ma shows he neares sore o oenal consumers and dslays he nformaon and hone number of he sore. Anoher case s T.G.I. Frday s resauran, hrough LBS osonng adversng mechansm of Von, consumers can enoy oyful adversng vdeos, whch can mmedaely dslay he neares sore and allow consumers o share nformaon o socal webses. Consumers can go o he neares resauran va moble ma navgaon or use he call funcon o call he resauran. The combnaon of moble adversng, brand, and he roduc aracs consumers no he raccal sream of locaon based commerce. Some as feaures, such as LBS adversng, mac he comeon sraeges of he hyscal sores. In hs aer, we develo a model of wo geograhcally dfferenaed sores whch sell homogeneous roducs. In addonal o he orgnal way of nformng cusomers, he sores can use LBS adversng o arac more consumers. To nduce more vss of cusomers, he sore has o some eer adversng effor. From he vew of he cusomers, he benefs of he moble as nclude boh search value creaon (such as value-added nformaon and servce, dscoun, eneranmen) and search cos reducon (e.g. he suor of GPS and LBS). Neverheless, even hough he oulary of moble devces s connuously ncreasng, some rooron of he eole sll have no own one ye. In hs aer, we consder wo yes of consumers: users wh a moble devce and users whou a moble devce. ach consumer s locaed a a dfferen geograhc oson. For hose cusomers whou a moble devce, hey don know eacly her geograhc locaon and he dsance o he sores. For hose cusomers wh a moble devce, hey have a chance o be nformed by a sore s LBS adversng and know her curren locaon. Wh he avalably of LBS as, how o develo he arorae LBS adversng level and roduc romoon dscoun rae o ence more cusomers and generae hgher rof becomes a new challenge. Mos of he esng LBS sudes are conduced from he echncal and sysem desgn ersecve, he works on he economc analyss and comeon sraegy of LBS are sll lle. In hs aer, we wll also nvesgae he mac of moble echnology on he comeng adversng and rcng sraeges of hyscal sores, and analyse he mac of marke srucure (he frs mover nvasve enry and he second mover defensve enry) on he moble LBS adversng adoon. The remander of he aer s organzed as follows. In secon 2, we revew he relaed leraures. Secon 3 we descrbe he model of hs aer. In secon 4, we dscuss he mlcaons of our analycal resuls. Fnally, secon 5 rovdes concludng remarks and offers fuure research drecons. 2 LITRATUR RVIW Adversng s an moran way for sores o nform cusomers he roducs. Sores can use nformave adversng o le cusomers o know he roducs and so ha cusomers can choose he bes o mee hey need (Soberman, 2004). Trole (1988) dsngush wo vews on adversng. One s he aral vew, ha adversng s rovdng roduc nformaon o he consumers and ncreasng comeon. The oher s he adverse vew; adversng s ersuadng he consumers 2
and ncreasng barrers o enry. In he suaon of no well dfferenaed roducs, he revous leraures on nformave adversng show ha he effec of adversng n ncreasng rce comeon s domnaed he effec of decreasng comeon. Ghosh and Sock (2010) show ha enhance adversng level may be assocaed wh hgher rofs and hgher rces for comeng sores. Wh he ncreasng growh of smar hones and ables, locaon-based servce becomes very oular. Many surveys forecas ha moble adversng revenue wll grow very quckly. For eamle, Garner says ha global moble adversng revenue s eeced o reach $11.4 bllon n 2013 (Garner, 2013). Accordng o IAB (Ineracve Adversng Bureau) and ech researcher Ovum, n he ne wo years, 19% of US moble markeers wll ncrease moble adversng sendng and lan o u her moble adversng budges by 50% or more (emarkeer, 2013). So ha moble adversng s an moran ssue for emergng moble commerce. The feaure of ubquy of moble devce rases he roles of locaon, me, and ersonalzaon o become more moran. I makes sores o rovde more suable adversemens o cusomers (Shoab & Rassan, 2012). In hs sudy, we wll consder he sores offer LBS adversng o ncrease her revenue n he roosed model. Cone can be any nformaon ha can be used o descrbe he suaon of any eny. Dey (2001) roosed hree knds of feaures for cone-aware alcaons are resenaon, eecuon and aggng. Coneual adversng s he argeed delvery of adversemens; aears on many meda, such as webses, moble browsers, and moble as. Many webses have offered coneual argeng as her man rooson (Zhang & Kaona, 2012). Wh argeed adversng, he consumers who have a srong reference o he frm s roduc are he argeed consumers, and frms have adversng more o hs segmen of consumers (Iyer, Soberman, & Vllas-Boas, 2005). The moble devces can receve real-me nformaon and many alcaons are coneaware, he ads can dslayed based on consumer s rofles and references. The hyscal sores can resen he nformaon and servces o cusomers. However, as consumers have dfferen references for roducs, he frms don have ably o adverse and sell her roducs o all knds of consumers. So ha he frms mus lm her range of adversng o he arge grou of consumers (Shy, 1996). Addonally, he consumer can choose he knds of ads ha he or she wan o receve on he moble devces (Dhar & Varshney, 2011). Through he moble devce wh GPS, he hyscal sores can ush he dscoun nformaon o nearby cusomers and arac hem o vs he sores. Laer we wll develo he omal dscoun rcng sraegy and a adversng level for he comeng sores. 3 TH MODL Wh he growh of smar hones, here s a new form of adversng ha negraes moble adversng wh LBS. The LBS echnology s used o non consumer locaon and rovde locaon-secfc adversemens or nformaon on her moble devces. Ths form of moble adversng s hghly argeed and ersonalzed. No only does serve cusomers well, s also good for he hyscal sores. LBS nclude servces o denfy a locaon of a erson, such as dscoverng he neares resauran or a frend. Ths knd of servces can reduce he searchng cos and ransacon cos. LBS can eede moble commerce hrough akng he form of couons or adversng dreced a cusomers based on her curren locaon. Nowadays, brck and morar busness owners have made an effor o ake advanage of moble commerce by ulzng moble caables, such as locaon based servces, and barcode scannng o mrove he cusomer eerence of shong n hyscal sores. Moble-commerce can ransform busness rocesses n erms of effcency and servce qualy as well as creae new consumer markes ha nvolve hghly argeed servces because of s unque characerscs, such as locaon and cone 3
awareness, ersonalzaon, and ransacon orenaon (Varshney, 2008). Adversng s gradually becomng a ar of he modern eole's daly lfe. Besdes radonal adversng, hyscal sores can choose LBS adversng o arac cusomers. We wan o know under wha knd of condons a hyscal sore ges more rof. Wha s he omal adversng and romoon dscoun rcng sraegy of he hyscal sores when a LBS adversng a s mlemened? How does he varaons n rofs for he hyscal sores, and how o choose he LBS adversng sraegy under comeon? Suose ha here are wo geograhcally dfferenaed sores S, { AB, }, sellng homogeneous roducs wh rce, he un cos of roducon s c. Assume he sze of he oenal marke s normalzed o 1; he cusomers are connuously locaed a a lne and ndeed wh [ 0,1] and φ ( 0< φ < 1) rooron of he consumers who have a moble devce (such as smarhone GPS). The wo hyscal sores are locaed a wo end ons of he lne. If a cusomer doesn own a moble devce or are no aware of any LBS a adversemen, he robably ha he/she wll vs sore S s α ( αa + αb < 1 ). Ths knd of cusomers does no know recsely he sores locaons. They vs one of he wo sores arbrarly, or don vs any one of he sores. The cusomers vs a sore f hey receved radonal adversng or worh-of mouh nformaon. The uly funcon of he consumer who s no aware of he LBS adversng s defned as n δ U = v, where v s value of he roduc and δ s he cos for user o search and ravel from hs/her locaon o sore S. We assume he cos δ s a random varable wh a value drawn from he nerval [ 0,δ ], whou any LBS (ma) suor. For hose cusomers wh a moble devce, he benef ganed from he moble adversemen ncludes wo ars: dscoun couon and LBS suor.

In racce, he sores adverse n he assgned locaons by he moble adversng laforms, and could change he LBS adversemen range conngen on her own comeon sraegy.

Obvously, when he oulaon of consumers who are aware of LBS adversng from sore S ncreases, he sore S s rof wll decrease.

As we can observe when rce s hgh and LBS adversng cos s low, he sores have hgher nenon o ado LBS adversng. In he gray regon, he sore wll ado LBS adversng and gan more rofs. In Fgure 2, he lgh gray regon (one enered) shows he suaon of only one sore mlemens he LBS adversng, n whch s romoon dscoun rae of he enran s r = ( c+ v) /2. We can fnd ha he hgher he rce, he lower romoon dscoun rae. Therefore, when he rce s hgh, he sore gves more benefs o he consumers, whch dmnshes he rof generaed from he LBS adversng marke. The rof of he sore whch ado he LBS adversng s π, ha conans he orgnal cusomers who buy a roduc whou 9

In Fgure 2, he dark gray regon (wo enered) shows he enry sraegy of he wo hyscal sores n adong LBS adversng. Comarng he gray blocks of Fgure 2, a he same rce level, he LBS adversng cos n he dark gray regon s lower han ha n he lgh gray regon. When here are wo sores mlemenng LBS adversng n he marke, he comeon becomes more nense, s harder for hyscal sores o make more rof from he LBS cusomers. r 1 β 0.5 0.8 0.4 0.6 0.3 0.4 0.2 0.2 0.1 0 0 r (only r (nvadng one sore enry) wh LBS ads) β (only (nvadng one sore enry) wh LBS ads) r (wo r (defendng sores wh enry) LBS ads) β (wo (defendng sores wh enry) LBS ads) (a) The mac of on romoon dscoun (b) The mac of on adversng level β Fgure 3.The mac of rce on dscoun and LBS adversng level.

In hs aer, ulzng he mehodology of game heorec and economc modellng, we analyze he romoon dscoun sraegy and LBS adversng level for comeng wo hyscal sores. The mac of 10
LBS on he hyscal sores s eamned n varous yes of comeve envronmens. We analyze enry sraegy of a hyscal sore n mlemenng LBS adversng when he frm has he ooruny o be he frs mover or have o face he challenge o be he second mover. We fnd ha he hyscal sores wll adverse more bu gve hgher dscouns o her cusomers when he rooron of consumers wh a moble devce s ncreasng. The rce and LBS adversng cos wll affec he sores decson on he adoon of LBS adversng. We fnd ha he economc nenon o ado LBS adversng s hgher for a frs mover han a second mover. There are several ssues whch can be furher suded. Frs, we assume ha he robably of a cusomer aware of a sore s LBS add s he same. I would be neresng o develo a model ha he cusomers have dfferen robably of beng aware. Second, he roduc rce s redeermned n our model. The decson of roduc rce can be furher analyzed by consderng dfferen suly chan scenaros. Thrd, he role of radonal adversng can be ncororaed no he model.
