Rules of k names are frequently used methods to appoint individuals to o¢ ce. They are two-stage procedures where a …rst set of agents, the proposers, select k individuals from an initial set of candidates, and then another agent, the chooser, appoints one among those k in the list. In practice, the list of k names is often arrived at by letting each of the proposers screen the proposed candida...

Rankings of schools, scholars, and journals emphasize ordinal rank. Journal rankings published by Journal Citation Reports (JCR) are widely used to assess research quality, which influences important decisions by academic departments, universities, and countries. We study refereed law journal rankings by JCR, Washington and Lee Law Library (W&L), and the Australian Research Council (ARC). Both ...

We analyze the e¤ects of family ties “the fetters of the sib”on the incentives for productive e¤ort. A family is here modelled as a pair of mutually altruistic siblings. Each sibling exerts e¤ort, or makes an investment, to produce output under uncertainty, and siblings may transfer output to each other. We show that altruism has a nonmonotonic e¤ect on e¤ort. Equilibrium e¤ort decreases (incre...

Abstract Although it has been established that excessive daily calorie intake contributes to the development of hypertension, relation between energy consumption and blood pressure in patients on stable antihypertensive therapy is not yet known. The aim study was evaluate 24 hours control therapy. Materials methods Cross-sectional included 141 hypertensive with age median 56.5 (45.00 ÷ 63.70) y...

We propose an evolutionary theory of institutional persistence and change. Many institutional changes are decentralized, with a large number of private actors informally adopting new practices that are later confirmed by changes in formal governance structures. For example, land tenure norms, conventional crop shares, inheritance practices, and traditional property rights all are informal insti...

Abstract. Seasonal forecasts have the potential to substantially improve water management particularly in water-scarce regions. However, global seasonal are usually not directly applicable as they provided at coarse spatial resolutions of best 36 km and suffer from model biases drifts. In this study, we therefore apply a bias-correction spatial-disaggregation (BCSD) approach precipitation, temp...

Current network access protocol stacks consist of a number of layers and components that are only loosely aware of each other. While this provides flexibility, it also results in a number of limitations, including high signalling latency due to duplicated tasks at multiple layers, security vulnerabilities, and deployment problems when new components and protocols are added. Most of currently on...

We study decentralized mechanisms for allocating firms into search pools. The pools are created in response to noisy preference signals provided by consumers, who then browse the pools via costly random sequential search. Surplus-maximizing search pools are implementable in symmetric Nash equilibrium. Full extraction of the maximal surplus is implementable if and only if the distribution of con...
