The role of power for distributive fairness

We employ an experimental labour setting to study fairness in the division of gains from productive activity. The focus is on the impact of power structures on allocation decisions and on fairness perceptions. Two types of actors are involved in generating a gain, but only one contributes actively by completing a real-effort task. In three treatments, decision power to divide the gain is assigned (1) to the inactive, (2) jointly to the inactive and the active, and (3) to the active. Results show that the impact of power goes beyond changing final allocations: it also significantly alters fairness perceptions. Decision power - in particular absolute power – mediates and significantly enhances self-serving biases. Results complement studies on the psychology of fairness perceptions. Moreover, the paper discusses implications for organizational design.

Towards an Efficient Evaluation of General Queries

Database applications often require to evaluate queries containing quantifiers or disjunctions, e.g., for handling general integrity constraints. Existing efficient methods for processing quantifiers depart from the relational model as they rely on non-algebraic procedures. Looking at quantified query evaluation from a new angle, we propose an approach to process quantifiers that makes use of relational algebra operators only. Our approach performs in two phases. The first phase normalizes the queries producing a canonical form. This form permits to improve the translation into relational algebra performed during the second phase. The improved translation relies on a new operator - the complement-join - that generalizes the set difference, on algebraic expressions of universal quantifiers that avoid the expensive division operator in many cases, and on a special processing of disjunctions by means of constrained outer-joins. Our method achieves an efficiency at least comparable with that of previous proposals, better in most cases. Furthermore, it is considerably simpler to implement as it completely relies on relational data structures and operators

HAR-TRU Sports: Serving Up Growth in 2011

Randy Futty, the General Manager of HAR-TRU Sports (HTS), a division of the Luck Companies set a deadline of mid August, 2011 to develop a five year strategic/growth plan for his business. In fiscal 2010, the division had achieved net sales of $10 million and Futty\u27s objective was to grow the business to$15 million by fiscal 2015. On the positive side, growth opportunities existed geographically in both the western U.S. and in global markets although it would be organizationally challenging to service such markets. Also, various new tennis accessory products and services were being developed by HTS to complement a myriad of existing products

Power accretion in social systems

We consider a model of power distribution in a social system where a set of agents plays a simple game on a graph: The probability of winning each round is proportional to the agent’s current power, and the winner gets more power as a result. We show that when the agents are distributed on simple one-dimensional and two-dimensional networks, inequality grows naturally up to a certain stationary value characterized by a clear division between a higher and a lower class of agents. High class agents are separated by one or several lower class agents which serve as a geometrical barrier preventing further flow of power between them. Moreover, we consider the effect of redistributive mechanisms, such as proportional (nonprogressive) taxation. Sufficient taxation will induce a sharp transition towards a more equal society, and we argue that the critical taxation level is uniquely determined by the system geometry. Interestingly, we find that the roughness and Shannon entropy of the power distributions are a very useful complement to the standard measures of inequality, such as the Gini index and the Lorenz curveWe acknowledge financial support from the Spanish Government through Grants No. FIS2015-69167-C2-1-P, No. FIS2015-66020-C2- 1-P, and No. PGC2018-094763-B-I0
