Multi-agent modeling <strong>of</strong> economic innovation dynamics <strong>and</strong> its implications 335<br />
competition are related to each other triggering different modes <strong>of</strong> action one <strong>of</strong><br />
which is novelty creation. Due to the difficulty to anticipate the time dependent<br />
frequency <strong>of</strong> these modes <strong>of</strong> action, due to the unpredictable outcome <strong>of</strong> individual<br />
novelty creating endeavors, <strong>and</strong> due to unknown social acceptance <strong>of</strong> these<br />
outcomes (in terms <strong>of</strong> diffusion) there is no possibility to assess or even to plan<br />
such a process in advance. Rather it necessitates to confine political influence or<br />
regulation to a trial <strong>and</strong> error perspective. 23 Nevertheless the exemplary simulation<br />
analysis given above shows that any kind <strong>of</strong> political regulation has to face an<br />
innovation dilemma: If innovation is successful on the individual as well as on the<br />
social level there is a high probability that it generates growth <strong>and</strong> if it generates<br />
growth, it generates additional emissions. <strong>The</strong> only self-organized way to circumvent<br />
this dilemma seems to be economic stagnation <strong>and</strong> crisis.<br />
Against this background three general options for regulation can be distinguished:<br />
(i) blocking the core <strong>of</strong> the innovation dynamics, (ii) fostering differentiation in<br />
favor <strong>of</strong> establishing environmental benign technologies as well as products <strong>and</strong> (iii)<br />
redirecting the innovation dynamics. Option (i) seems to be unfeasible in that it is<br />
incompatible with a given market <strong>and</strong> competition environment. Option (ii) is <strong>of</strong>ten<br />
pursued by political authorities but faces the problem <strong>of</strong> establishing <strong>and</strong> protecting a<br />
niche or—to take it the other way round—it is confronted with the constraints <strong>of</strong><br />
path dependencies (cf. Nill 2009). Due to these constraints for options (i) <strong>and</strong> (ii) the<br />
following discussion focuses on option (iii). Without going into the details <strong>of</strong> an<br />
instrumental debate it is assumed that regulatory authorities are willing <strong>and</strong> firms are<br />
able to implement a predefined path <strong>of</strong> reducing emissions. This is more specific<br />
than the usual framing <strong>of</strong> the problem to reduce emissions (e.g. in the debate about<br />
climate research) in that economic agents as the main subject <strong>of</strong> these policy options<br />
are explicitly taken into account.<br />
<strong>The</strong> first regulatory regime to analyze more closely is a short term dynamic<br />
incremental dynamic abatement <strong>of</strong> emissions. Setting the initial change factor <strong>of</strong><br />
emission coefficient to 95% (i.e. in the beginning <strong>of</strong> the simulation, when creating an<br />
innovative product, a firm has to reduce the emissions per produced unit by 5%<br />
compared to the mean emission factor <strong>of</strong> the branch) the innovating firms have to<br />
comply with the obligation <strong>of</strong> reducing this change factor <strong>of</strong> emission coefficient<br />
(model parameter M; cf. section 5 (2)) by further 5% every 20 time steps (5 years).<br />
This means that the speed <strong>of</strong> technological progress in terms <strong>of</strong> the reduction <strong>of</strong><br />
emission factors is accelerated more <strong>and</strong> more over the whole simulation. This<br />
regime is depicted in Fig. 10.<br />
In formal terms this means<br />
Mt ðÞ¼0:95 for t < 20; Mtþ ð 20Þ<br />
¼ Mt ðÞ 0:05 for all t: ð18Þ<br />
Figure 11 indicates that it is not before t=100 (i.e. only after 5 regulation periods)<br />
that the emissions in two <strong>of</strong> the four sectors start to be reduced leading to an overall<br />
23<br />
For a specification <strong>of</strong> this perspective <strong>of</strong> political regulation cf. Kemp <strong>and</strong> Zundel 2007 <strong>and</strong><br />
Beckenbach 2007.
