On the estimation of stock-market reaction to corporate layoff announcements

This study investigates the stock-market reaction to layoff announcements where more than 1000 workers are affected. We employ a dummy variable regression (DVR) version of the market model and compare the results obtained using ordinary least squares (OLS) versus exponential GARCH (EGARCH), and value-weighted (VW) versus equally weighted (EW) market index. We find that the stock market responds negatively to layoffs attributed to low demand. We also find that contrary to prior research, the market reacts positively to restructuring-related layoffs on the announcement date. This pattern of market reaction is observed regardless of the market index used or the parameter estimation methods employed, although the empirical results indicate that using EGARCH/VW market index tends to generate fewer statistically significant test results and smaller (in the absolute size of the cumulative) abnormal returns (ARs). Taken together, our study provides additional support for the claim that studies of stock-market reaction to corporate events must account for the time variation in return volatility. Ignoring these could result in erroneous inferences.     

The perceived probability of job loss and future labour market outcomes

Longitudinal survey data are used to test the degree to which worker expectations of future job loss are correlated with changes in labour market status. Three major findings are reported. First, perceived probabilities of expected job loss are only weakly related to both exogenous job separations and subsequent transitions to unemployment and inactivity. Second, while fears of job loss tend to persist across time and job spells, they do so at a highly diminishing rate. Third, quit intentions are strongly correlated with both voluntary separations and transitions to alternative employment, and do not diminish greatly across successive employment spells.     

A NOTE ON SEMIPARAMETRIC ESTIMATION OF FINITE MIXTURES OF DISCRETE CHOICE MODELS WITH APPLICATION TO GAME THEORETIC MODELS*

We view a game abstractly as a semiparametric mixture distribution and study the semiparametric efficiency bound of this model. Our results suggest that a key issue for inference is the number of equilibria compared to the number of outcomes. If the number of equilibria is sufficiently large compared to the number of outcomes, root‐n consistent estimation of the model will not be possible. We also provide a simple estimator in the case when the efficiency bound is strictly above zero.     

The comprehensive business exam: Usefulness for assessing instructional and student performance outcomes

The authors explore the results of the Comprehensive Business Exam (CBE) administered to business majors during their senior-year business capstone course. The study results identified students' SAT and grade point average as a predictor of CBE performance, and variables that explain the correlation between CBE performance, SAT score, and grade point average are discussed. This study expands the research stream by demonstrating how faculty can use CBE information to more deeply assess student learning at both the course and instructor level than is possible with the Major Field Test for Bachelor's Degree in Business.     

Genetische Untersuchungen im Versicherungsbereich – Offene Fragen im Rahmen von § 18 GenDG

The paper refers to legal questions that arise in connection with the collection and use of genetic data in the context of private insurance. The content and meaning of § 18 GenDG is described. Then, § 18 GenDG is set in relation to notification requirements out of the VVG. The paper exemplarily emphasizes that, despite the codification of GenDG, specific legal problems arise. Accordingly, the paper provides solutions to overcome these problems. Particular problems refer to the role of genetic data of third parties and according relations to the family history, possibilities to communicate genetic data by the insured in case of medical indication, the ratio of predictive and diagnostic genetic testing and the range of the total limits of § 18 I 2 GenDG.     

Legitimizing Negative Aspects in GRI-Oriented Sustainability Reporting: A Qualitative Analysis of Corporate Disclosure Strategies

Corporate sustainability reports are supposed to provide a complete and balanced picture of corporate sustainability performance. They are, however, usually voluntary and thus prone to interpretation and even greenwashing tendencies. To overcome this problem, the Global Reporting Initiative (GRI) provides standardized reporting guidelines challenging companies to report positive and negative aspects of an organization’s sustainability performance. However, the reporting of “negative aspects” in particular can endanger corporate legitimacy if perceived by the stakeholders as not being in line with societal norms and values. Starting from the theoretical lenses of economics-based disclosure theories and socio-political theories of disclosure, the focus of this study therefore was to analyze the communicative legitimation strategies companies use to report “negative aspects,” i.e., negative ecological and social impact caused by corporate activity. Using qualitative content analysis of GRI-oriented sustainability reports from companies listed on the US Dow Jones Industrial Average Index and on the German DAX Index, we identified six legitimation strategies. We discuss these strategies regarding to symbolic and substantial management of legitimacy. We show that symbolic legitimation strategies aiming at modifying the perception of legitimizing stakeholders dominate in the reports at hand. Such persuasion, however, does not meet the requirement of impartiality as postulated by the GRI guidelines. Building upon this conclusion we propose a concise characterization of “negative aspects” and develop a GRI-compliant schema of reporting about them. In doing so, we offer a way to improve the overall “balance” of sustainability reporting contributing to a true and fair view in sustainability disclosure.     

Inclusive business,human rights and the dignity of the poor: a glance beyond economic impacts of adapted business models

In recent years, a considerable amount of research on adapted business for developing countries focused on the impact such endeavours have on the respective companies as well as on the affected people. However, the main emphasis within management sciences was on the economic outcomes or (even more distinct and often) on the question of how to integrate the poor into business models and value chains. Until now, further aspects of a dignified human existence were merely covered as a side note. The article focuses on the influence of inclusive business approaches on various aspects of human dignity and provides explorative insights as a basis for future theory building. The aim is to uncover how human dignity is affected by different business approaches for the poor including and beyond economic outcomes. After giving an insight into the essence and meaning of human dignity in connection to various human rights, the articles refers to a number of illustrative cases of inclusive business. The analysis culminates in the insight that dignity can be (and sometimes already is) assured and promoted by deliberately including the poor into relevant value‐added business processes. If this is the case, an enhanced dignity is not merely the result of increased incomes but stems from a variety of effects. However, such positive effects are not an inevitable outcome of any inclusive business initiative.     

Testing for profitability and contestability in banking: evidence from Austria

The paper investigates the determinants of banking profitability and banking market conditions in Austria. We conduct a panel econometric analysis which allows for testing the hypotheses which have become the most prominent in the literature on bank profitability: the structure–conduct–performance hypothesis, the efficient‐structure hypothesis and the relative market‐power hypothesis. Further, we test whether Austrian banking markets are, on average, contestable. A newly compiled dataset covering more than 700 Austrian banks ranging over the period from 1995 to 2002 is used to carry out these econometric analyses. The empirical findings support the view that the Austrian banks do exert, on average, some local market power. However, the gains in terms of excess profits are rather minor as a result of low deterrence powers of the incumbent banks.
