Communicating production outcomes as gains or losses,operator skill and their effects on safety-related violations in a simulated production context

In this study, violation-producing conditions from an organizational and individual point of view are investigated. In concrete terms, framing effects of production outcome displays in relation to production goals, the risk of a technical accident, as well as person-related variables and their impact on violations are investigated based on the theoretical assumptions of prospect theory and risk-taking. It is assumed that violations are more likely when performance is below the aspiration level associated with an anticipated loss. A 2?×?3 factorial experimental design (n?=?118) was selected in accordance with the ‘Asian Disease’ decision scenario in the form of a computer-simulated task environment Simulation Waste Water Treatment. Participants acted out the role of a production supervisor running a plant. Experimental conditions were (1) the framing of individual performance outcomes in relation to the production goals in terms of losses or gains, and (2) the risk (20, 35, and 5%) with which an accident (a deflagration) might occur through using a corner-cutting procedure. A significant main effect of the framing conditions and no effect of risk conditions or interaction effect emerged. An additional path analysis shows the influence of risky decision-making and acquired skills in terms of knowledge of the safety-related procedure on a violation. In summary, violations are strongly affected by (a) framing effects of production outcomes when the performance is below the aspiration level and (b) person-related variables, in particular risky decision-making and skill. Results strongly emphasize that we found violation-producing conditions over and above what has so far been proposed and give rise to our claim that communicating production outcomes as gains and the increase of skill increases the likelihood of compliance with safety-related procedures.     

Schumpeter 1911: Farsighted Visions on Economic Development

This paper presents to the English-speaking reader a sample of material contained only in Schumpeter's first German edition (1911) of Theorie der wirtschaftlichen Entwicklung , material subsequently omitted from later German editions and from the English translation. The newly-translated material, presented here for the first time in English, comprises a substantial part of the second chapter, only available in a completely rewritten version, and fully half of the famous seventh chapter, which has not been previously available at all in English. This material merits attention today because it contains remarkable and farsighted visions on economic theory that may inspire current efforts to devise models of economic and social evolution. In order to better appreciate the original text, we briefly introduce the "background" to Theorie and its revisions, briefly describing the social and intellectual environment of the time. We then discuss how the entrepreneur evolved over the three editions of Theorie (from 1911 to 1934) in view of the shift in Schumpeter's personal and intellectual life and outline the most important implications raised by the first German edition of 1911. Finally, we use Schumpeter's own statements to settle the obstinate confusion on the publication year of Theorie in favour of the year 1911.

Continuous rainbow options on commodity outputs: what is the real value of switching facilities?

We develop real rainbow option models to value an operating asset with the flexibility to choose between two commodity outputs. We provide a quasi-analytical solution and a numerical lattice solution to a model with continuous switching opportunities between two commodity outputs, taking into account operating and switching costs. The models are applied to an illustrative case, demonstrating that the quasi-analytical solution and the lattice approach provide near identical results for the asset valuation and optimal switching boundaries. We find that the switching boundaries generally narrow as prices decline. In the presence of operating costs and temporary suspension, however, the thresholds diverge for low enough prices. A fertilizer plant with flexibility between selling ammonia and urea is valued in an empirical section using our real option models. Despite the high correlation between the two alternative commodities, ammonia and urea, there is significant value in the flexibility to choose between the two. Both strategic and policy implications for stakeholders in flexible assets are discussed, with some generalisations outside the fertilizer industry.     

An empirical analysis of green supply chain management in the German automotive industry

The purpose of this paper is the empirical investigation of the status quo of green supply chain management in the German automotive industry from a practitioner's point of view. Several aspects of green supply chain management, such as the point of time of implementation, the driving forces, the relevance of intended goals and their particular realization and the adoption of eco‐programs with suppliers and customers as well as internal and external barriers are analyzed. Furthermore, the link to different performance criteria is tested by inductive statistics in order to show the potential of green supply chain management for competitiveness. For this study, managers from the automotive supply industry in Germany were asked about their estimations in this regard. The main conclusion is that managers express the need for green supply chain management on the one hand but also see corresponding problems in terms of required resources on the other hand. Furthermore, the analyses show that green supply chain management leads to higher performance in terms of several performance criteria.

Climate Change and Asset Prices: Are Corporate Carbon Disclosure and Performance Priced Appropriately?

This paper empirically assesses the relevance of information on corporate climate change disclosure and performance to asset prices, and discusses whether this information is priced appropriately. Findings indicate that corporate disclosures of quantitative greenhouse gas (GHG) emissions and, to a lesser extent, carbon performance are value relevant. We use hand‐collected information on quantitative GHG emissions for 433 European companies and build portfolios based on GHG disclosure and performance. We regress portfolios on a standard four factor model extended for industry effects over the years 2005 to 2009. Results show that investors achieved abnormal risk‐adjusted returns of up to 13.05% annually by exploiting inefficiently priced positive effects of (complete) GHG emissions disclosure and good corporate climate change performance in terms of GHG efficiency. Results imply that, firstly, information costs involved in carbon disclosure and management do not present a burden on corporate financial resources. Secondly, investors should not neglect carbon disclosure and performance when making investment decisions. Thirdly, during the period analysed, financial markets were inefficient in pricing publicly available information on carbon disclosure and performance. Mandatory and standardised information on carbon performance would consequently not only increase market efficiency but result in better allocation of capital within the real economy.     

Comparison of Methods for Evaluation of the Convolution of Two Compound R 1 Distributions

In the present paper we compare four methods for evaluating the convolution of two compound R 1 distributions by counting the numbers of elementary algebraic operations required. Two of the methods are applicable in general, whereas the remaining two are restricted to the case when the two compound distributions have the same severity distribution. This case is discussed separately. We consider in particular the special case when this common severity distribution is concentrated in one, that is, evaluation of the convolution of two R 1 distributions.
