How not to measure sustainable value (and how one might)

Sustainability is a complex multidimensional concept that entails economic, environmental, and social aspects. The sustainable value (SV) method developed by F. Figge and T. Hahn [Ecol. Econ. 48(2004) 173-187] is one of the most promising attempts to measure sustainability performance of firms. SV measures corporate contributions to sustainability by valuing resource use based on the opportunity cost, which must be estimated. This paper critically examines Figge and Hahn's estimator for opportunity cost, and shows that the proposed estimator rests on a number of strong, unrealistic assumptions. Evidence from Monte Carlo simulations conducted by authors shows that the proposed estimator performs very poorly even under ideal conditions. Having identified shortcomings in the SV method, we review some econometric approaches with a proven statistical foundation, which might be usefully applied in the present context.     

Are women expected to be more generous?

This paper analyzes if men and women are expected to behave differently regarding altruism. Since the dictator game provides the most suitable design for studying altruism and generosity in the lab setting, we use a modified version to study the beliefs involved in the game. Our results are substantial: men and women are expected to behave differently. Moreover, while women believe that women are more generous, men consider that women are as generous as men.

Performance comparison of alternative stochastic volatility models and its determinants in energy futures: COVID-19 and Russia–Ukraine conflict features

This paper studies the volatility dynamics of futures contracts on crude oil, natural gas, and gasoline. An appropriate Bayesian model comparison exercise between seven stochastic volatility (SV) models is estimated using daily prices for our futures contracts between 2005 and 2023. Moreover, to assess the impacts of COVID-19 and the Russia–Ukraine conflict on volatility, we analyze these two subsamples. Overall, we find that: (i) the Bayes factor shows that the SV model with -distributed innovations outperforms the competing models; (ii) crude oil contracts with different expiry dates may require the introduction of leverage effects; (iii) the $$-distributed innovations remain the appropriate model for the COVID-19 subsample, while jumps are needed in the conflict period; and (iv) other Bayesian criteria more appropriate to short-term predictive ability—such as the conditional and the observed-date deviance information criterion—suggest other rank order to model our futures contracts, despite the agreements for the best models.     

International comovement of stock market returns: A wavelet analysis

The assessment of the comovement among international stock markets is of key interest, for example, for the international portfolio diversification literature. In this paper, we re-examine such comovement by resorting to a novel approach, wavelet analysis. Wavelet analysis allows one to measure the comovement in the time–frequency space. In this way, one can characterize how international stock returns relate in the time and frequency domains simultaneously, which allows one to provide a richer analysis of the comovement. We focus on Germany, Japan, UK and US and the analysis is done at both the aggregate and sectoral levels.     

Intersectionality of Ethnic and Entrepreneurial Identities: A Study of Post‐War Polish Entrepreneurs in an English City

An understanding of ethnic and immigrant entrepreneurship is developed in this paper by exploring how ethnic and entrepreneurial identities intersect. Bourdieu's concept of habitus frames the analysis of narratives of five post‐war Polish entrepreneurs in Leicester. The narrative analysis illuminates the multilayered and nuanced nature of identities. The Polish origin of these entrepreneurs’ habitus was interpreted in light of individual and collective experiences gained growing up in the United Kingdom. While Polish identity was pertinent, it did not define the narrative of entrepreneurship. Our contribution is a theoretically informed, rich qualitative study of what ethnic identity means to individuals and how it intersects with entrepreneurial identity.     

Mapping Biodiversity Indicators and Assessing Biodiversity Values in Global Forests

Biodiversity loss is a problem of global concern affecting ecosystem functioning and services provided to humans. The Millennium Ecosystem Assessment is built on a conceptual framework that links biodiversity with the services ecosystems provide to society and human welfare. Numerous empirical studies have measured ecosystem goods and services in terms of economic values; however, less evidence is available of the indirect effect of biodiversity on these values. Based on this, we first compile market and non-market forest valuation studies and, secondly, explore the potential of an econometric modelling exercise by conducting a worldwide meta-analysis. This exercise aims to highlight the role of biodiversity indicators on valuation. In this way, we can study the underlying transmission mechanisms that explain to what extent biodiversity is related to human welfare. Furthermore, we also propose to evaluate the magnitudes of the respective distributional impacts, including the different ecosystem goods and services under consideration. Our results show that biodiversity indicators may have an underlying effect on forest ecosystem values, which also depend on the type of ecosystem services. Lastly, the results are discussed and analysed with respect to their policy implications concerning biodiversity conservation.     

The effect of benchmarked performance measures and strategic analysis on auditors’ risk assessments and mental models

As the audit environment becomes more demanding and complex, so does the set of analytical tools available to an auditor. The purpose of this paper is to examine the effect of two complex audit technologies commonly used by auditors, benchmarking of performance measures and strategic analysis, on the risk judgments of auditors carrying out the initial planning of an audit. We conduct an experiment that utilizes a Balanced Scorecard for organizing and evaluating analytical evidence about the performance of business units within a large client. Our first principal finding is that external benchmarking can cause an auditor to focus on performance measures that are unique to a business unit and disregard performance measures that are common to multiple business units but not benchmarked. However, our second finding is that an in-depth strategic analysis completed prior to assessing a client’s business risk or risk of material misstatement allows an auditor to incorporate more information from performance measures in risk assessments regardless of whether the performance measures are benchmarked. Strategic analysis facilitates a more balanced and accurate assessment of the risks across the business units being evaluated. We also provide evidence that the latter result occurs because in-depth strategic analysis allows auditors to develop a more complete mental model of a client, which has been a long time belief of advocates of business risk audit methodologies and consistent with current and emerging auditing standards on risk assessment.

Predictors of organizational citizenship behavior in relation to environmental and health & safety issues

Abstract

Organizational citizenship behaviors (OCBs) in relation to the environment and health and safety, commonly shaped by individual and voluntary initiatives, are essential factors for a smooth and efficient organization in firms. Our research explores the factors affecting OCBs related to environmental and health and safety issues in a Multinational Enterprise (MNE) operating in the oil & gas sector. More in detail, we tested the influence of personal attitudes, self-efficacy, organizational support and social norm on OCBs related to environmental and health and safety issues. The results show that personal attitudes and self-efficacy positively influence OCBs related to environmental and health and safety issues and those factors are influenced respectively by perceived organizational support and social norm. Moreover, we found that attitudes play a full mediation between social norm and OCBs related to environmental and health and safety issues and that organizational support on organization citizenship behavior for the environment and health and safety that is partially mediated through the perceived self efficacy. Finally, the results of our investigation are contextualized in the theoretical and managerial frameworks pointing to a number of avenues for further research.     

Market Structure and the Environmental Implications of Trade Liberalization: Russia's Accession to the World Trade Organization

We investigate the environmental impacts of Russia's World Trade Organization (WTO) accession with a computable general equilibrium model incorporating imperfectly competitive firms, foreign direct investment and endogenous productivity. WTO accession increases CO₂ emissions through technique (?), composition (+) and scale (+) effects. We consider three complementary policies to limit CO₂ emissions: cap and trade, emission intensity standards and energy efficiency standards. With imperfectly competitive firms, gains from WTO accession result with any of these policies. If we assume perfectly competitive market structures, the negative environmental impacts of WTO accession are smaller and no net gains arise when environmental regulation involves energy intensity or efficiency standards.
