It is known from a previous paper [3] that Katona’s Intersection Theorem follows from the Complete Intersection Theorem by Ahlswede and Khachatrian via a Comparison Lemma. It also has been proved directly in [3] by the pushing–pulling method of that paper. Here we add a third proof via a new (k,k+1)-shifting technique, whose impact will be exploared elsewhere. The fourth and last of our proofs ...

Do higher wages elicit reciprocity and hence higher productivity? In a field experiment with 266 employees, we find that paying above-market wages, per se, does not have an effect on productivity relative to paying market wages. However, structuring a portion of the wage as a clear and unexpected gift (by offering a raise with no further conditions after the employee has accepted the contract –...

W HERE A WILL CONTAINS A GIFT to the "children" of a named person, a question of construction arises with regard to the right of an adopted child to participate in the distribution.' Where recognized, this right has been upheld on either or both of two grounds: (a) that the testator intended that he share in the gift,2 or (b) that adoption legally vested him with the status of a natural child. ...

How does one decide on the perfect gift? We look at an important tradeoff between desirability and feasibility in gift giving using construal level theory as a framework. We propose that givers construe gifts abstractly, and therefore choose gifts high on desirability attributes over gifts high on feasibility attributes. Support for these propositions emerges in studies examining giver and rece...

The impact of gifts on deposit balances and customer satisfaction was examined in a longitudinal field experiment conducted at a commercial bank. Gifts increased deposit balances, survey response rates, and customer satisfaction compared to the no-gift control. Several factors were manipulated within the gift treatment: gift type, the accompanying message, and the sequence of gift value, which ...
