“…While the empirical literature on this subject is quite extensive, the theoretical literature is relatively scarce. Indeed, most of the theoretical works on ETSs deal with the optimal number of allowances to be allocated on the market and on the related carbon prices (see, e.g., Grüll & Taschini, ; Fell, Burtraw, Morgenstern & Palmer, ; Kollenberg & Taschini, ; Perino & Willner, ). Several other studies (see, among others, Malueg, ; Milliman & Prince, ; Jung, Krutilla & Boyd, ; Unold & Requate, ; Requate, ) have focused on aggregate cost‐savings deriving from the adoption of new technologies in cap‐and‐trade systems.…”
