Although the performance measures employed in our study are proper scoring functions, conveying their implications using business-friendly terminologies will advance the importance of this study and in general the problem of modeling seller behavior.

We propose to evaluate an action based on the change in sale-through rate, the ratio of successful sales over all listings, and the seller’s average revenue per listing. Given that listings created at time t may affect sales of formerly created listings that are still active, it is non-trivial to compute these measures of effectiveness. We decided to include items sold within 2 weeks from time t in the calculation of a ¯t ’s effectiveness, while including items sold after 2 weeks from their original listing date in the computation of a ¯t ’s effectiveness, where t is the time interval where they are sold.

Second, traders are constantly moving between markets, which means that the equilibrium point of all the markets is constantly changing (recall the transaction prices of Fig. 2 (b)). We know from [9] that zip takes several trading days to identify market equilibrium, and since this is changing every day, zip is always Table 3. The global efficiencies of sets of market with different connection topologies from left to right, chain, ring, star and fully connected networks. The table gives results for markets using both zi-c and zip traders, and for both cda and ch markets.
