|Description=An important aspect of TIMER is the endogenous formulation of technology development, on the basis of learning by doing, which is considered to be a meaningful representation of technology change in global energy models ([[Azar and Dowlatabadi, 1999]]; [[Grubler et al., 1999]]; [[Wene, 2000]]). The general formulation of 'learning by doing' in a model context is that a cost measure Y tends to decline as a power function of an accumulated learning measure: | |Description=An important aspect of TIMER is the endogenous formulation of technology development, on the basis of learning by doing, which is considered to be a meaningful representation of technology change in global energy models ([[Azar and Dowlatabadi, 1999]]; [[Grubler et al., 1999]]; [[Wene, 2000]]).

For technologies in early stages of development, other factors may also contribute to technology progress, such as relatively high investment in research and development ([[Wene, 2000]]). In TIMER, the existence of a single global learning curve is postulated. Regions are then assumed to pool knowledge and 'learn' together or, depending on the scenario assumptions, are partly excluded from this pool. In the last case, only the smaller cumulated production in the region would drive the learning process and costs would decline at a slower rate. | For technologies in early stages of development, other factors may also contribute to technology progress, such as relatively high investment in research and development ([[Wene, 2000]]).
