Stated-preference surveys for the economic valuation of environmental resources typically assume no uncertainty in the hypothetical valuation scenarios. However, the outcomes of environmental policies are uncertain. We explored the effects of including information on probabilities of attribute improvement and provision in choice experiments. Our results suggest that stating explicitly a high pr...
Environmental risk assessment is an essential element in any decision-making process in order to minimize the effects of human activities on the environment. Unfortunately, often environmental data tends to be vague and imprecise, so uncertainty is associated with any study related with these kind of data. Essentially, uncertainty in risk assessment may have two origins – randomness and incompl...
In this paper, we consider a problem in environmental policy design by applying optimal stopping rules. The purpose of this paper is to analyze the optimal timings at which the government should adopt environmental policies to deal with increases in greenhouse gas concentrations and to reduce emissions of SO2 or CO2 under the continuous-time Knightian uncertainty. Furthermore, we analyze the ef...

The current paper presents a theoretical framework on the assimilation of Green IS in organizations. The assimilation of Green IS comprises three stages, namely, Green IS initiation, adoption, and routinization. The different stages of assimilation are proposed to be affected by different groups of factors. Based on institutional theory, organizational information processing theory and organiza...
Shogren, J.F. and Crocker, T.D.. 1990. Adaptation and the option value of uncertain environmental resources. Ecol. Econ., 2 : 301-310. Just as ecology has benefited from the economic theory of optimizstion, economics can benefit from the ecological theory of adaptation. We examine the impact of short-term, non-genetic adaptive self-protection on the values individuals attach to uncertain prospe...
This paper investigates the relationship between contingency factors, strategic management accounting and firm performance. Due to the development and expansion of organizations and their connections to the industrial competition, it is usable that the organization rely more on non-financial information than financial. The management accounting and financial accounting literature have highlight...
The concept of adaptive management has, for many ecologists, become a foundation of effective environmental management for initiatives characterized by high levels of ecological uncertainty. Yet problems associated with its application are legendary, and many of the initiatives promoted as examples of adaptive management appear to lack essential characteristics of the approach. In this paper we...
This paper addresses the question of how uncertainty in costs and benefits affects the difficulty of reaching a voluntary agreement among sovereign states. A measure of “difficulty” is constructed relating to side-payments necessary to make an agreement a Pareto-improving move. Using a simple model, it is shown that uncertainty actually makes agreement easier. * Donald Bren Professor of Environ...
As awareness of deep uncertainties in many disciplines has grown over the last half-century, researchers have developed frameworks, typologies, and taxonomies to understand, analyse, communicate them. Uncertainty analysis is critically important fields study that deal with large, complex, societally-coupled problems, such as those dealing environmental change. However, yet, no wide-ranging revi...
