Summary of Market Assumptions Sensitivity Cases.

This table shows how the different market actor behaviors were combined into four different cases. Case Name corresponds to the names used in Figure 9, and Run refers to the run number, which may be used to view run results in the supporting information file (Data S1). Occasional User Price Response and Regular User Price Response represent consumer behaviors that address how occasional ethanol users and regular ethanol users responded to ethanol price. The model variable names are “Occasional User Price Attractiveness Weighting” and “Regular User Price Attractiveness Weighting.” Station Owner Investment (New Tank) and Station Owner Investment (Repurpose Old Tank) represent dispensing station owner behaviors that reflect the likelihood that a station owner would invest in a new tank or in repurposing an old tank in order to offer high-blend. In the model, these are two functions called “Investment ‘Hit Rate’” and “Investment ‘Hit Rate’ (RP)” for new and repurposed tankage, respectively. Conversion Capacity Investment Price Response represents conversion capacity investment behavior, measuring the responsiveness of upstream investment to ethanol price. In the model, this is called, “Impact of Price on Cellulosic Growth Rate.”
