Still, we must reach the gifts. Some psychology studies have found that people place inescapable conclusion that the spent on the gift was a very high premium on the worth of things they have almost entirely wasted. received as gifts. If this is indeed the case, then gift giving The loss in value described above — the difference could at times be a form of “value creation.” At the very least between what was paid for the gift and what the gift is there may still be social reasons to engage in gift giving, even worth to the recipient — is one example of the economic if it does result in a deadweight loss. concept of “deadweight loss.” Technically, deadweight loss Certain government actions may also produce dead- is defined as the waste resulting from economic inefficien- weight losses.
