They're determined by supply and demand, as the others have said. It's not at all true that supply is unlimited---there are production costs for a champion: artwork, game code, balancing, lore, etc. That's why some skins/champions cost more than others upon release. A champion is likely to be reduced in price once demand drops off. However, there's a few special cases---Riot keeps all the "Recommended" champions at a low price so new players can easily afford them. This ensures a smoother learning curve because it encourages players to try simple champions before complicated ones.
