Diminishing marginal utility (DMU) is a basic tenet of economic and psychological models of judgment and choice, but its determinants are little understood. In the research reported here, we tested whether insensitivities in valuations of dollar amounts (e.g., $40, $100) may be due to inexact mappings of symbolic numbers (i.e., "40," "100") onto mental magnitudes. In three studies, we demonstra...

Issues around water – its quality, use, availability and environmental value – can be a major point of tension between mineral projects and local communities. Failure to manage these issues appropriately can jeopardise the obtaining of regulatory approvals for new projects and place at risk the ‘social licence to operate’ of existing operations. Conversely, there may also be significant opportu...

This paper explores the idea that a proper valuing of natural environments is essential to (and not just a natural basis for) a broader human virtue that might be called ʻappreciation of the goodʼ. This kind of valuing can explain, without any commitment to a metaphysics of intrinsic values, how and why it is good to value certain natural phenomena for their own sakes. The objection that such a...

The IT productivity paradox has largely been resolved at the industrial level. At the firm level however, there is still much to understand regarding how IT contributes to firm performance. This paper investigates the performance impacts of two modes of IT valuation – efficiency and KM (Knowledge Management), by taking two external environmental factors – dynamism and hostility – into account. ...

This paper examines the capability of firm fundamentals in explaining the cross-sectional variation of credit default swap spreads. We start with the Merton (1974) model, which combines two major credit risk determinants into a distance-to-default measure. We convert the distance-to-default measure into a raw CDS valuation based on a constant hazard rate assumption and then map the raw CDS valu...

The aim of this paper is to present a framework to bank valuation based on two generally acceptable valuation models that are not specific to banks: the model of discounted Equity Cash Flow to Equity (ECF) and the model of discounted Residual Income (RI). As emphasized by Koller, Goedhart and Wessels (pp. 663, 2005) [1] in a bestselling book on the valuation of firms, the valuation process of a...

This study examines the valuation relevance of greenhouse gas emissions under the European Union Carbon Emission Trading Scheme (EU ETS). We posit that carbon emissions affect firm valuation only to the extent that a firm’s emissions exceed its carbon allowances under a cap and trade system and the extent of its inability to pass on carbon related compliance costs to consumers and end users. We...

This article describes an innovative e-business strategy planning e-valuation approach, based on adaptive algorithmic modeling methods for solving a wide class of e-business and strategic management problems. The proposed methodology is based on basic ideas and concepts of four key-field interrelated sciences, i.e. Computing Science, Applied Mathematics, Management and Economic Sciences. Furthe...
