Provision Point Mechanisms and Field Validity Tests of Contingent Valuation

Past field validity tests of contingent valuation have relied on voluntary contribution mechanisms to elicit actual willingness to pay, and may overestimate hypothetical bias because of free riding in the actual contributions. This paper argues that provision point mechanisms are a preferred alternative for field validity tests of contingent valuation because they increase the proportion of demand revealed in cases in which public goods can be provided in a step function. The results of a contingent valuation validity study of participation in a green electricity pricing program that uses a provision point mechanism are reported, and hypothetical open-ended and dichotomous choice responses are compared to actual participation. Calibration of hypothetical responses is also explored.     

Integrating science and local knowledge in environmental risk management: A decision-focused approach

This paper explores how a structured decision process, based on methods from the decision sciences, can contribute to the integration of local and scientific knowledge in environmental decision making. Emphasis is placed on the use of key decision structuring steps and analytical tools to help ensure the systematic treatment of both fact-based and value-based knowledge claims. Practical methods are discussed for communicating and evaluating values and technical information across participants and cultures in ways that are methodologically rigorous and encourage different sources of credible knowledge to be considered on equal footing. Examples are presented from water use planning in British Columbia, Canada, where stakeholder consultations at 22 hydroelectric facilities demonstrate specific techniques that can be used to clarify values, to explore hypotheses, to clarify uncertainties, to identify and evaluate options, to make value-based choices, and to facilitate mutual learning.     

Streets, Malls, and Supermarkets

We develop a model of competition between shopping centers, comparing competitive outcomes in three alternative modes of retail organization, namely: streets (in which neither developers or retailers internalize agglomeration effects between products); malls (in which developers internalize); and supermarkets (in which both developers and retailers internalize). For a fixed number of centers: (i) converting streets to malls intensifies developer (but not retailer) competition, which increases product range (i.e., the number of shops built by the developers) and consumer surplus, reduces profits, and has ambiguous effects on welfare; (ii) converting streets to supermarkets intensifies retailer and developer competition, has ambiguous effects on product range (number of shops), reduces profits, and increases social welfare. With free entry both conversions reduce the number of centers and, if there is excess entry, conversion to supermarkets (but not malls) unambiguously increases welfare.     

An analysis of some aspects of regulatory risk and the required rate of return for public utilities

This paper uses a modification of the continuous time asset pricing model of Cox, Ingersoll, and Ross to analyze the effect of regulatory risk on the cost of capital. Analysis shows that random errors in setting the allowed rate of return can either increase or decrease the cost of capital depending on other regulatory parameters. However, the analysis suggests that regulatory risk is not material.     

Developing Theories of Strategy Using Dominance Criteria

This article identifies key features of the strategy concept as a basis for reviewing existing theories of strategy. It also provides an agenda for future research. the article argues that there is a decision hierarchy in a firm, and defines strategy as the highest-level decision in the hierarchy. Consequently, strategy has to exhibit what may be called three features of dominance: vertical dominance, horizontal dominance, and dynamic dominance. A vertically dominant strategy is one that determines, directly or indirectly, other decisions of a firm. A horizontally dominant strategy seeks to optimize the value of the firm according to some criteria. Dynamic dominance implies that strategy should affect the subsequent decisions of a firm over a relevant period of time. With few exceptions, existing theories of strategy are issue-oriented and focus largely on horizontal dominance. More research should, therefore, be directed towards vertical and dynamic dominance criteria. If a comprehensive theory of strategy which satisfies the three dominance features cannot be developed, it is suggested that development should be directed towards integrating behavioural and economic approaches.     

Unemployment Duration and Inflows onto the Disability Support Pension Program: Evidence from FaCS LDS Data

From the administrative data of the Australian Department of Family and Community Services it is found that a large proportion of Disability Support Pension (DSP) recipients transferred from unemployment benefits. Among those who transferred to DSP from unemployment benefits, a large proportion experienced multiple spells of income support receipt prior to the transition and a majority had more than a half‐year pre‐transition unemployment duration, with the average pre‐transition unemployment duration being more than one year. These findings suggest that the unemployment benefit is not simply a‘hold‐on’ benefit for those who experienced the unemployment—DSP transition. This article further examines what factors are associated with the transition. It is found that, among other things, the probability of transition to DSP from unemployment increases with duration on unemployment benefits.     

Institutional Dynamics on the U.S. Court of Appeals: Minority Representation Under Panel Decision Making

This article assesses how the institutional context of decisionmaking on three-judge panels of the federal Court of Appealsaffects the impact that gender and race have on judicial decisions.Our central question is whether and how racial minority andwomen judges influence legal policy on issues thought to beof particular concern to women and minorities when serving onappellate panels which decide cases by majority rule. Properanalysis of this question requires investigating whether womenand minority judges influence the decisions of other panel members.We find that the norm of unanimity on panels grants women influenceover outcomes even when they are outnumbered on a panel.     

Retroactive Liability or the Public Purse?

The article addresses the question of whether responsibility for pollution created in the past should be retroactively applied to firms, or if the costs of cleaning up existing pollution should be financed by the public. We show that making firms liable for retrospective environmental costs can weaken the incentive to take precautions against future environmental costs. This follows since public financing of these costs can lead to greater prospective risk deterrence by allowing firms to more fully internalize the costs of future environmental risks. However, an analysis of existing public financing approaches highlights a set of dangers associated with their practical use.
