Estimating census and survey undercounts through multiple service contacts

Abstract

During the past decade a tremendous amount of work has been done on studying the homeless. The 1980s saw many disconnected city‐specific counts of the numbers of homeless that sought to obtain some information on their characteristics. As these studies began to be published, there was a growing awareness of the inadequacy of the methods available and the variety of interests that prompted the studies. The 1980s also saw the growth of new methods and models for counting and the coordination of efforts for multidisciplinary studies. This paper describes the development of new models for counting and new methods of sampling in time and space.     

Illegal markets and the social costs of rent-seeking

This paper argues that making goods or services illegal results in an increase in the social costs associated with rent-seeking. The increased social cost is in the form of negative externalities that result from market participants use of coercion and violence in attempts to control trade in the illegal good. Consequently, the social costs of rent-seeking will exceed the value of resources dissipated in rent-seeking competition. And, where the external costs exceed the undissipated portion of the Tullock cost, the social cost of rent-seeking is greater than the sum of Tullock and Harberger costs.     

论非法证据的证据能力

非法证据的证据能力问题,涉及犯罪控制和人权保障、实体公正与程序正义的价值选择。对其证据能力的不同选择,直接关系到刑事诉讼目的的能否实现。在我国,对于非法证据的证据能力如何,理论界说法不一。从两大法系主要国家立法及实践,并结合我国立法现状及国情来看,非法证据排除规则的建立是我国诉讼民主化的必然要求。     

遏制行政不作为违法的途径

行政不作为违法是指行政主体能够履行而不履行或不及时履行,从而使公民、法人或其它社会组织合法权益受到侵害的行为.从制度层面完善责任行政机制,是遏制和惩治行政不作为违法现象的关键.
