Constrained allocation problems with single-peaked preferences: An axiomatic analysis 总被引:1,自引:0,他引:1
Özgür Kıbrıs 《Social Choice and Welfare》2003,20(3):353-362
We introduce a new class of problems that contains two existing classes: allocation problems with single-peaked preferences
and bankruptcy problems. On this class, we analyze the implications of well-known properties such as Pareto optimality, strategy-proofness,
resource-monotonicity, no-envy, equal treatment of equals, and two new properties we introduce, hierarchical no-envy and independence
of nonbinding constraints. Unlike earlier literature, we consider rules that allow free-disposability. We present characterizations
of a rule we introduce on this domain. We relate this rule to well-known rules on the aforementioned subdomains. Based on
this relation, we present a characterization of a well-known bankruptcy rule called the constrained equal awards rule.

It is well known that the unimodal maximum likelihood estimator of a density is consistent everywhere but at the mode. The authors review various ways to solve this problem and propose a new estimator that is concave over an interval containing the mode; this interval may be chosen by the user or through an algorithm. The authors show how to implement their solution and compare it to other approaches through simulations. They show that the new estimator is consistent everywhere and determine its rate of convergence in the Hellinger metric. 相似文献

The liberalization of international financial flows and foreign direct investment has induced countries to use diverse measures to attract inflow of foreign capital and foreign direct investment, which is expected to have a positive effect on the growth of GDP and thus a positive effect on social welfare. Tax exemption, reduction of tax rate, tax holiday, or diverse subsidies are some of the most important measures used. In this paper we study international tax cooperation, i.e., countries change and especially reduce tax rate for corporate income or for asset revenues to attract inflow of foreign direct investment. Both theoretical and empirical studies have shown the sensibility of foreign direct investment decision with respect to tax rate differences between home countries and host countries. In general, more inflow of foreign direct investment can be expected if the tax rate of the home country is lower than that of foreign countries. This is the main reason for international tax cooperation. In this paper we propose a simple model to prove the sub-optimal Nash non cooperative solution in a two-country tax-competition game. The model shows that international tax cooperation can improve welfare of the participating countries. How to reach a cooperative solution for an international tax competition game (ITCG) is therefore an important issue for further discussions and studies. International institutions can play a crucial role to reach international tax cooperation or international tax harmonization. 相似文献

自我思想道德建设是个体发展和完善自己主观世界的思想道德活动,而不是传统意义上的思想道德教育方法或原则.作为相对独立的思想道德活动,自我思想道德建设具有自己的运动发展规律,也因之具有独特的研究论域.自我思想道德建设的学科依据、结构、过程和效益等是自我思想道德建设研究论域的基本构成. 相似文献
