After Modigliani,Miller, and Hamada: A new way to estimate cost of capital

In this article, we discuss the impact of financial debt on shareholder value using a new approach that aims: (a) to explain the effect that leverage from debt has on a stock’s systematic risk, or what we shall call here “the systematic cost of leverage,” and (b) to account for default risk in the cost of equity, or what we shall call here “the cost of default.” Our assessment of systematic risk is based on a stochastic approach that is materially different from the one proposed by Hamada: the risk premium remunerates the investor for the probability of equity (expressed as market value) generating a return below that of the risk‐free rate. Furthermore, the approach we use to account for default risk is derived from reduced‐form models, but in this case, (a) we use real probabilities of default and not risk‐neutral probabilities, and (b) we extend the approach to stocks.     

The price of sanctions: An empirical analysis of German export losses due to the Russian agricultural ban

The aim of this paper is to contribute to the vivid political discussion on the consequences of the Russian agricultural import ban on the German export market by quantifying export losses that German agri-food exporters encountered on the Russian market due to the agricultural import ban of 2014. A gravity-type approach is used to measure the sanction effect in a panel of German agri-food exports covering the period from January 1999 to June 2018. The ban effect is disentangled from a sequence of different geopolitically- and economically driven episodes. Once macroeconomic developments of the Russian economy as well as individual stages of decreasing trade cooperation in the preban period are accounted for, the import ban reduced German agri-food exports significantly but was not the major cause. Therefore, a simple elimination of the ban will not be enough to restore trade to the presanctions level.     

Do they always say no? German consumers and second‐generation GM foods

European consumers and, in particular, German consumers are known to be very critical toward the introduction of genetically modified (GM) foods. It is analyzed here whether German consumers do reject second-generation GM foods, too. Whereas first-generation GM crops induced producer-related benefits, second-generation GM crops are associated with consumer-oriented benefits like an improvement of nutritional quality. The determinants of demand for second-generation GM rapeseed oil are investigated within an online survey of 1,556 German consumers. It is elaborated how two functional properties of the product matter; that is, long-chain omega-3 fatty acids and the cholesterol-lowering effect of phytosterols. It turns out that GM rapeseed oil is neglected by 74% of all respondents. Output traits, however, will increase the probability of purchases of GM rapeseed oil. This is more the case for long-chain omega-3 fatty acids than for phytosterols.     

Stakeholder value analysis: a methodology for intergrating stakeholder values into corporate enviromental investment decisions

Increasingly, decision‐makers in industry are being faced with complex investment decisions created and made emotive by diverse stakeholder expectations. Investments with the potential to have an impact on a company's environmental performance are a prime example of this since they are driven by multidimensional impacts, many of which are difficult to quantify in scientific and monetary terms. This paper presents a stakeholder value analysis (SVA) model, which can be used to address such problems, using a multiple‐attribute decision methodology. This decision tool has been developed and validated through a series of industrial applications, one of which is outlined here. This application describes the use of the tool in a company context whereby stakeholders from within the company are canvassed for their priorities and views. The SVA tool is used not only to guide and support this process but also to analyse the data and consequently produce output decision metrics, which express the preferences of all relevant stakeholders and which can therefore be more confidently used to support the final decision.

Optimizing joint production of timber and carbon sequestration of afforestation projects

Optimizing harvesting decisions has been a matter of concern in the forestry literature for centuries. However, in some tropical countries, growth models for fast-growing tree species have been developed only recently. Additionally, environmental services of forests gain importance and should be integrated in forest management decisions. We determine the impact of a joint production of timber and carbon sequestration on the optimal rotation of a fast-growing species in north-western Ecuador, comparing different optimization approaches and taking the latest developments of the Kyoto Protocol into account. We find that payments for carbon sequestration have substantial impact on the rotation length: in contrast to an optimum of 15 years when focusing on timber production only, joint production leads to a doubling of the rotation length, which means that timber harvest should be postponed until the end of the carbon project.     

Enhancing Concept Test Validity by Using Expert Consumers

In standard concept testing practice, consumers may be invited to participate in a test if they use or possess the product. However, merely using or possessing a product is no guarantee that a consumer has the level of product knowledge that is necessary for judging the concept. Conducting a concept test with consumers who lack the necessary product knowledge may jeopardize the validity of the test results. That is, the results of such a concept test may not accurately indicate how consumers will evaluate the real product. To ensure the validity of concept test results, Jan Schoormans, Roland Ortt, and Cees de Bont suggest that consumers who are invited to participate in a concept test should possess a degree of product knowledge. When a consumer is asked to evaluate a concept, their product expertise allows them to understand product information faster, fill in missing information, and learn more easily. Consumers with product expertise are better able to discriminate between important and unimportant aspects of a product. They are also better able to infer benefits from a product's physical attributes. To explore the effects of consumer expertise on the quality of the evaluations provided by concept tests, the authors conducted two experiments, both of which resemble actual concept tests. The first experiment examines the effect of consumer expertise on the results of a concept test for a major innovation, Videotext. This experiment tests the hypothesis that the similarity between the evaluations of a concept and an actual product will be greater for consumers with a high level of product-category expertise than for consumers with low product-category expertise. The results of the experiment clearly support the idea that product-category expertise enhances a respondent's ability to evaluate concepts in a test of major innovations. From this, it is concluded that only respondents with high product-category expertise should be used for concept tests of major innovations. The second experiment explores the effects of product expertise on consumers' evaluations of a minor innovation, a redesigned coffee maker. This experiment tests two hypotheses. First, it is proposed that consumers with high product expertise give more consistent evaluations in a concept test than consumers with low product expertise. Second, it is suggested that consumers with product expertise generate more stable evaluations over time than consumers without product expertise. The results of this experiment clearly indicate that using consumers with moderate to high levels of product expertise is beneficial to the validity of the results from concept tests of minor innovations.     

Leading by Example: Values-Based Strategy to Instill Ethical Conduct

Years of research clearly shows that relying on traditional organizational power bases is not effective when companies want to promote business ethics and performance. It is not only that the use of legitimate power to establish ethics codes and coercive power to punish employees who do not comply does not work; this study—based on a multi-method research approach in the retail industry—indicates that the classic iron fist leads to unethical business values and lower service performance. But there is a light at the end of the tunnel for forward-looking managers. The ethical attitudes and behaviors of employees within international organizations is a dynamic variable that is possible to change by the use of values-based leadership. Our extensive study of a large grocery store chain owned by a multinational corporation indicates that managers who lead by example will boost team values and commitment.     

Aufschwung in Deutschland weiter kräftig — Anspannungen nehmen zu

The business cycle upswing in Germany has gained strength and breadth. In addition to private consumption, the expansion is now also supported by investment and foreign trade. The latter benefits from growing exports to the euro area, where the economy is gaining momentum. Since the euro area upswing rests on solid fundamentals, the ECB should be able to start tapering without putting the economy at risk.     

“Resistance is futile”: estimating the costs of managing herbicide resistance as a first‐order Markov process and the case of U.S. upland cotton producers

A 2012 survey of upland U.S. cotton producers was analyzed to determine the factors contributing to changes in weed management costs (WMCs) after the identification of herbicide‐resistant weeds. An ordered probit regression estimated changes in WMC as a first‐order Markov process. The most important determinants of post‐resistance cost increases were initial WMCs, adoption of labor‐intensive remedial practices, and wick application of herbicides. Cultivation and mechanical/chemical‐intensive practices did not increase WMCs. Post‐resistance changes in WMC ranged between $85 and $138 ha^?1, depending on the practices adopted. WMCs increased by $88 ha^?1 when cost‐neutral practices were adopted. The in‐sample aggregate costs of managing herbicide resistance ranged between $25 and $53 million, depending on the types of adopted practices.
