A Prospect Theory Analysis of California's Initiatives in Implementation of its Zero Emission Vehicles (ZEV) Mandate1

In 1990, the state of California passed the pioneering mandate on zero emission vehicles (ZEV). This technology‐forcing regulation is aimed at improvement of air quality and protection of public health from the adverse effects of air pollutants from automobiles. Facing severe opposition from the auto industry, the mandate has been revised a number of times, most recently in 2003, whereby the requirement for ZEVs have been made to align with the pace of technology development. Review of strategies used in implementation of the mandate has revealed greater emphasis on the economic incentives for rather than on environmental merits of ZEVs. Using prospect theory as the framework for analysis, the reasons have been explored. The findings of the study help us to understand how decisions are made with respect with to deviations from a mental anchor point and through the process of evaluation of losses and gains.

Bounding the number of contributors to mixed DNA stains

We derive a simple inequality for the probability of observing a given DNA profile when assuming a fixed number of unknown persons have contributed to the mixed stain. We then show how this inequality can be used to obtain an upper bound for the number of unknown contributors needed to be considered.     

行政立法程序的民主与效率

行政立法程序既应追求行政行为的效率,又应追求立法行为的民主。在民主与效率之间,行政立法程序应以民主为更高的价值追求。针对我国目前的法律、法规及行政立法的现状,在行政立法准备制定阶段应建立更为民主的制度,但同时也不能忽略行政立法程序的效率。
