Accommodative competitive entry policies and telecommunications regulation Author(s): Mark Kolesar, Dennis L. WeismanJournal: infoISSN: 1463-6697Year: 2003 Volume: 5 Issue: 1 Page: 34 ? 40DOI: 10.1108/14636690310473872 Publisher: MCB UP LtdAbstract: Accommodative competitive entry policies (unbundling, resale and interconnection) yield contestable retail telecommunications markets. The combination of setting efficient prices for network elements and allowing competitors to choose their preferred level of wholesale quality renders the retail market self-regulating with respect to both price and quality. Any overhang of regulation at the retail level under these conditions is potentially harmful to fostering a competitive market outcome.Keywords: Competition, Control, Market entry, Telecommunications JKLVvw?????????????????????? ? ? ? ?  ?ε?????????????????????r??[,h?=Bh?=B>*B* CJKHOJQJ^Jph^<0h?=Bh?=BB*CJKHOJQJ^JaJo(ph'h?=BB*CJKHOJQJ^JaJph*h?=BB*CJKHOJQJ^JaJo(ph0h?=B5?B*CJKHOJQJ\?^JaJo(ph3h?=Bh?=B5?B*CJKHOJQJ\?^JaJph-h?=Bh?=BB*CJKHOJQJ^JaJph#Lw?????? 3 4 ??????????1$gd?=B 4 ?      1 3 4 ????????h?=Bh?=Bo(,h?=Bh?=B>*B* CJKHOJQJ^Jph^<-h?=Bh?=BB*CJKHOJQJ^JaJph01?82P??. ??A!?"?#??$??%????? ????N@??N ck?e $1$a$$CJKHPJ_HaJmH nHsH tH$A@???$ ؞???k=?W[SOBi@???B nf?h?*CJaJph^<4????Lw??????36?0???0???0???0???0???0???0???0???0???0??Lw??????36??0???0  4  4 4 \c66w???????66??=B?@J??/JJ?{4@@??Unknown????????????G??z ??Times New Roman5??Symbol3&? ?z ??Arial;???[SOSimSun q??hxպ?zպ?z?z?!-!),.:;?]}????    & 6"0000 0 000000??? ? ?????=?@?\?]?^???([{?  0 0 00000??;?[??????????r33 HX(??????????????????????????=B2??xrfxrf???????Oh??+'??0L??????? ??   ,4<D?xrfNormalxrf2Microsoft Office Word@??G@`s?D?@??.E?z?????՜.??+,??0?
