abstract = {Many new technologies exhibit clear generational changes. The empirical literature on technology diffusion traditionally analyses the spread of new technologies generically. We use data from the mobile phone industry, where first-generation (1G) and second-generation technologies (2G) can be clearly identified, to analyse the role of generational effects in diffusion. The results from a generation specific approach differ significantly from those of a generic model. There are positive within-generation network effects. 1G (2G) has a positive (negative) effect on 2G (1G) diffusion. Both generations are substitutes for fixed phones. Effects of competition and payment schemes are also analyzed. --  -- Useissa uusissa teknologioissa on selvi\"{a} sukupolvia. Teknologian diffuusion empiirinen kirjallisuus k\"{a}sittelee kuitenkin perinteisesti vain ns. geneeristen teknologioiden levi\"{a}mist\"{a}. T\"{a}ss\"{a} tutkimuksessa k\"{a}yt\"{a}mme aineistoa ensimm\"{a}isen (1G) ja toisen (2G) sukupolven k\"{a}sipuhelimista sukupolvien v\"{a}listen vaikutusten analysoimiseen. Geneerinen ja sukupolvien v\"{a}listen vaikutukset salliva malli tuottavat hyvin erilaisia tuloksia. Sukupolvien sis\"{a}lt\"{a} l\"{o}ytyy positiivisia verkostovaikutuksia. Tuloksemme osoittavat my\"{o}s, ett\"{a} 1G (2G) vaikuttaa positiivisesti (negatiivisesti) 2G (1G) levi\"{a}misnopeuteen. Molemmat sukupolvet ovat substituutteja kiinteille puhelimille. Tutkimme my\"{o}s kilpailun ja maksuk\"{a}yt\"{a}nt\"{o}jen vaikutuksia.},
