Additionally, experimental errors that provide observations not representative of the true underlying behaviour, mean that observations obtained from these experiments cannot be regarded as always valid. To combat the problem of erroneous ...

Under common scenarios, i.e., when there is the opportunity to learn by "starting small" or when "no-compete" clauses cannot be enforced ex-post, we show that nancing experimentation can become harder precisely when it is more pro table, i.e., for lower valu...
