Prevention versus Treatment under Precautionary Regulation: A Case Study of Groundwater Contamination under Uncertainty

Policy discussions on agricultural pollution problems characterize prevention as more cost effective and precautionary than ex post treatment. We derive conditions under which treatment alone is more cost effective in situations involving multiple sources of emissions, multiple sites affected, and a commonly used precautionary approach to uncertainty. We also show that a greater degree of precaution can result in less reliance on prevention. An empirical case study indicates that treatment alone is the most cost-effective means of dealing with nitrate in most Maryland community water system wells. The use of leaching prevention measures is restricted to the most intensive poultry producing areas. The incremental cost of precaution is substantial.     

Market and institutional forces in industrial relations: the development of national collective bargaining, 1910–1920

This article reviews recent trends in the historiography of British industrial relations, and highlights a growing emphasis on the influence of employers and impersonal economic forces. In response, the article argues for a renewed recognition of trade unions as a proactive force in the development of industrial relations systems. This view is supported by analysis of the influence of market and institutional forces upon the spread of national collective bargaining. The conclusion is that commercial pressures on employers were relatively unimportant in a process driven by human agency, institutional forces, and wider economic pressures.

对商誉的再探讨

商誉是无形资产中最为特殊的组成内容，过去人们封其性质和构成有不同的看法。在知识经济时代的今天，无形资产的性质和范畴认识得到深入，商誉的构成内容与无形资产的泉多组成内容有很多相同之处，商誉的实质就是多项未入账无形资产的总和。商誉的确认与计量问题也就转换为对企业自创无形资产的确认与计量，知识经济下应确认和计量对描述企业财务状况起关键作用的自创无形资产。但在不确定和充满风险的经济环境下，应积极稳妥地确认自创无形资产。自创无形资产的计量可按不同特点选择采用成本基础定价法、市场基础定价法、经济定价法。     

DEFAULT RISK AND DIVERSIFICATION: THEORY AND EMPIRICAL IMPLICATIONS

Recent advances in the theory of credit risk allow the use of standard term structure machinery for default risk modeling and estimation. The empirical literature in this area often interprets the drift adjustments of the default intensity's diffusion state variables as the only default risk premium. We show that this interpretation implies a restriction on the form of possible default risk premia, which can be justified through exact and approximate notions of "diversifiable default risk." The equivalence between the empirical and martingale default intensities that follows from diversifiable default risk greatly facilitates the pricing and management of credit risk. We emphasize that this is not an equivalence in distribution, and illustrate its importance using credit spread dynamics estimated in Duffee (1999) . We also argue that the assumption of diversifiability is implicitly used in certain existing models of mortgage-backed securities.
