团队绩效改进的目标应该与质量、服务或者产量等竞争优势直接联系起来,因为,改进过程本身并不会直接产生竞争优势。     

Strategy Proof Scoring Rule Lotteries for Multiple Winners

We develop a lottery procedure for selecting multiple winners that is strategy proof. The rule assigns points to each candidate based on any standard scoring rule method, and then uses one draw to select a single winning set of candidates in proportion to their collective score. In addition to being strategy proof, the lottery rule is also shown to have several other attractive normative properties. Violations of some other important normative properties are noted as well.     

Een indelingsprobleem

Summary A branch and bound algorithm is given to solve the following problem: To each pair of elements (i,j) from a set X={l,…, n} a number r_ij with r_ij≥ 0, r_ij=r_ij and r_ij= 0 has been assigned. Find a prescribed number of disjoint subsets P₁…,P_m from X, such that Experiments indicate that an optimal solution is usually found in a small number of iterations, but the verification may be rather time consuming. The algorithm may be used to find the minimum value of m for which a partitioning of X with z= 0 exists. The algorithm appears to be efficient for finding this ‘chromatic number of a graph’.     

AID, ECONOMIC FREEDOM, AND GROWTH

Foreign aid has often been intended by donors to entice recipient nations into policy and institutional reforms favorable to private sector economic development. In this study, we investigate the relationship between aid and changes to economic freedom in recipient nations over the 1990–2000 decade. The evidence is mixed. In general, we find that foreign aid has no significant effect on economic freedom overall. However, using a hedonic approach on the different categories of economic freedom, we find that aid has still managed to contribute toward a policy and institutional environment favorable to growth, as the different categories of economic freedom improved by aid more than offset those which are harmed by aid, in terms of their impact on growth .
