Corporate environmental policy and abnormal stock price returns: An empirical investigation

This paper examines the correlation between the excess stock market returns and the adoption of an environmental protocol by companies. The underlying hypothesis that I test is whether evidence of the adoption of environmental policy, prosecution by an environmental agency or the routinized training of staff in environmental protocols, which proxies for the willingness of managers to invest for the long term, is associated with superior economic returns to shareholders. I find that both the adoption of an environmental policy and prosecution for breach of environment standards have significant explanatory power in an analysis of excess returns.

Economics and underdetermination: a case study of urban land and housing economics

Underdetermination, associated with the Duhem–Quine thesis,is a familiar if under-researched theme in economics. In thelight of this, we examine the development of urban land andhousing economics. Through its Cartesian dualistic delineationof theory and data, the contemporary mainstream approach appearsunable to circumvent the problem of underdetermination. In effect,it employs the strong version of Duhem–Quine in its retentionof the assumption of a single, unitary competitive market (andassociated access–space trade-off). Conversely, we highlightthe affinity of Ely's (and the later Columbia School's) approachto pragmatists Dewey and Peirce, which provides a more fruitfulbasis for explanation.
