A Comment on Weak Disposability in Nonparametric Production Analysis

In his 2005 paper in this journal, Kuosmanen argues that Shephard's specification of weak disposability in activity analysis (DEA) models is not correct. We show that Shephard's specification does satisfy weak disposability and is the "smallest" technology to do so.     

Why economic sanctions always fail — the case of Rhodesia

Demands for the imposition of economic sanctions under UN auspices on South Africa have been voiced for quite some time. Rhodesia was the first country ever to be subjected to a full obligatory embargo by the UN Security Council. An analysis of the embargo against Rhodesia will therefore help to answer the question whether an embargo on South Africa stands a chance of success.     

The Relationship Between Leaders’ Group-Oriented Values and Follower Identification with and Endorsement of Leaders: The Moderating Role of Leaders’ Group Membership

In this article, we hypothesize that leaders who display group-oriented values (i.e., values that focus on the welfare of the group rather than on the self-interest of the leader) will be evaluated more positively by their followers than leaders who do not display group-oriented values. Importantly, we expected these effects to be more pronounced for leaders who are ingroup members (i.e., stemming from the same social group as their followers) than for leaders who are outgroup members (i.e., leaders stemming from a different social group than their followers). We tested our hypotheses in two studies. Results of a field study (N = 95) showed the expected relationship between leaders’ group-oriented values and followers’ identification with their leaders. A scenario study (N = 137) replicated the results and extended it to followers’ endorsement of their leaders. Overall, these findings suggest that displaying group-oriented values pays off more for ingroup than for outgroup leaders.
