- Using the arbitrary max for a Gas Limit vote for as a discontinuity around private benefit. This is similar to what the paper mentions, but I suspect that any gas limit vote for max increase or decrease provides a semi-arbitrary cutoff.
Not sure what you mean by this. If you mean, using situations where the gas limit was suddenly upvoted or downvoted to examine what happens when supply is changed but demand is unchanged, and by doing so estimate the private benefit curve, that is exactly what Estimating cryptocurrency transaction demand elasticity from natural experiments is doing.
