We explain how the common practice of size-discovery trade detracts from overallfinancial market efficiency. At each of a series of size-discovery sessions, traders report theirdesired trades, generating allocations of the asset and cash that rely on the most recent exchangeprice. Traders can...

Laboratory experiments reporting on shortfalls from allocative efficiency of allocation mechanisms depend on the induced-values methodology, which cannot be extended to the field. Harstad [2011] proposes to observe efficiency of allocation mechanisms without knowing motivations via behavior in...

Economic experiments conducted in laboratories employing an induced-values methodology can report on allocative efficiencies observed. This methodology is limited by requiring the experimenter to know subjects' motivations, an impossibility in field experiments. Allocative efficiency implies a...
