10、ies' decisions regarding their strategic response to the EU ETS, we propose that there are three types of impact from the EU ETS that need to be taken into account in order to understand the incremental effect of the

11、 EU ETS. The first type is the impact from direct cost resulting from a company's need to buy allowances: The cost for covering its direct carbon emissions influences future investment decisions and technology choice

13、its direct carbon cost into its product prices: The company generates an indirect cost effect on other companies with positions in the value chain after the emitter. Thus the impact of indirect cost reflects the indirect

14、 emissions that a company generates with its demand for CO2-intense products further up the value chain.</p><p>　　Third, we argue that the impact from uncertainty surrounding the implementation of the EU ETS

15、 is an important factor that needs to be considered when studying companies' strategic decisions (compare Hoffmann and Trautmann 2006). Indeed there is little understanding of the relevance of uncertainty in the cont

17、ote that the third type of impact, uncertainty, cannot be viewed isolated from the impact from direct and indirect cost. Uncertainty can cause strategic reactions independent of cost effects (Aragón-Correa and Sharm

18、a 2003), but may also moderate the strategic response to cost effects (Marcus and Kaufman 1986). Hoffmann and Trautmann 2006 showed a correlation between the reported impact of the EU ETS on investment decisions and the

19、level of perceived uncertainty, indicating interdependence betwe</p><p>　　Some authors have argued that the role of uncertainty can only be understood when taking a company's industry specific context in

20、to account (Hrebiniak and Snow 1980). We argue that the industry specific context is a particularly important parameter as it reflects the relative importance of direct or indirect emissions and the local or global chara

24、to the incremental effect from the EU ETS. Thus we specifically analyze the effect that would not be there without the EU ETS. Technology strategy sets the focus on investment decisions rather than on decisions regarding

33、its cost from direct emissions. In the case of the power generation sector the cost from direct emissions may be reflected as opportunity cost in the electricity price. Consequently, the EU ETS has an indirect impact on

36、e in the first half of 2005. Of course this increase is driven by multiple factors such as the oil and gas price and cannot be assigned entirely to effects from the introduction of the EU ETS. However, according to the F

40、 results from the limited predictability and planning reliability that the trading system creates in investment decisions (Trautmann et al. 2006). This limited predictability results from both price uncertainty regarding
