A welfare analysis of "junk" information and spam filters
No full textThis paper analyses the equilibrium effects of individual information filters. Information is modelled as advertisements which are distributed across a population of consumers with heterogeneous preferences. An advertisement that provides knowledge about a product with little or no utility for a consumer is considered junk. Filters are characterised by their level of tolerance. The quality of the filter is measured in terms of the share of useful items in the total set of items passing the filter. It is shown that in conditions of decentralised competition, multiple equilibria arise. A social optimum can be achieved by demanding each consumer to reject a certain percentage of advertisements, leaving the choice of what is rejected up to the consumer him/herself.global information society, advertising, junk information, spam filter, Internet regulation

Space junk: Behavioural economics and the prioritisation of solutions
No full textThe use and exploration of outer space is, according to the Outer Space Treaty (OST), to be carried out for the benefit and interest of all parties. Outer space is critically important to the defence and national security interests of many nations, none more so than the United States. Over time, a significant space junk problem has emerged. There is growing recognition of this problem and reason to believe that it will only get worse if current activities continue. Space junk presents a threat to the national security interests and economic interests of spacefaring nations. Various solutions are being proposed and developed. This paper presents an economic perspective and, in a particular, a behavioural economics perspective, on the space junk and national security problem. As various potential technological solutions emerge, we are interested in the obstacles that may stand in the way of an optimal prioritisation of the alternatives
Moral Good, the Beatific Vision, and God’s Kingdom Writings by Germain Grisez and Peter Ryan, S.J.. Edited by Peter J. Weigel
No full textFor close to half a century, the work of Germain Grisez has been highly influential, and his writings continue to receive considerable attention from philosophers and theologians of diverse viewpoints. His co-author for this work is the professor and noted moral theologian Fr. Peter Ryan, S.J., currently the executive director of the Secretariat of Doctrine and Canonical Affairs of the United States Conference of Catholic Bishops (USCCB).

This work is an ideal source for students, scholars, ministers and lay persons interested in basic questions of Christian theology, the philosophy of religion, ethical theory, and Catholic doctrin
