How has the financial crisis affected earnings management? A European study

The article aims to investigate whether and how in the European Union (EU), the burst of the 2008 financial crisis affected misrepresentation of financial information due to earnings management. By analysing a sample of 11 844 firm-year observations listed in the EU over the period 2006–2012, an event study methodology allows us to calculate and compare country-by-country abnormal accruals over the estimation period and over the event period. Our findings validate our research hypothesis and suggest a decrease of misrepresentation in the large majority of the European countries after the burst of the financial crisis. The results take part in the debate in the accounting literature about the change of earnings management over a financial crisis and have several implications for standard setters and regulators that could learn how the common incentives of entities to attract potential investors during a crisis could lead them to provide a high-quality financial reporting.     

Sparkling wine choice from supermarket shelves: the impact of certification of origin and production practices

We report the results of a study based on revealed and stated preference data on choice of Prosecco wines in retail stores close to the origin of production in Northern Italy. Emphasis is placed on ability to reconcile the utility structure of stated preference data with that underlying revealed preference data. We extend the analysis to cover nonattendance of key attributes, such as price and certification of origin, while controlling for the large range of brand effects.     

Anti-Waste Labeling and Consumer Willingness to Pay

ABSTRACT

Food waste is an important topic in the general context of food consumption sustainability and ethical consumption. Several studies have focused on environment-friendly labeling schemes based on different “ethical attributes,” such as organic, fair trade, and locally grown. However, the effect of a labeling scheme based on food waste prevention has never been studied. In the current work, experimental auctions were used to investigate the effect of a certification about containing food waste within a certain threshold on participants’ willingness to pay. The product chosen for the auctions was the French baguette (500 g) packaged with a paper wrapper. Furthermore, we examined whether the effect would be moderated by different communication strategies about the consequences of wasting. Specifically, two different frames of reference were used: the first is based on the carbon footprint, the other on the water footprint. Our results showed that waste prevention–based labeling positively affected participants’ willingness to pay and that this effect was enhanced by the carbon footprint frame of reference.     

Is It Good to Talk? Information Disclosure and Organizational Performance in the UK

The disclosure of information by management to employees varies significantly between workplaces. The effects of this variance on organizational performance are analysed using WERS98 data. The results show that the impact of information disclosure on organizational performance is more complex than is often assumed in the literature. Overall, there is a significant impact, both direct and indirect, and this varies depending on the level of employee organizational commitment, the type of information disclosed and the performance outcome involved. On the whole, the positive effects are less in union settings and in situations where unions are strong.     

Quality and Quantity in Test Validity: How can we be Sure that Psychological Tests Measure what they have to?

During the twentieth century, many authors have offered their contributions to the controversial subject of test validity. Thus, the concept of validity seems to be quite a simple idea until one looks at the literature on the subject. Validity can be defined as “the degree to which the test actually measures what it purports to measure,” but the question of how to define validity and how to test it is both an old question and a never-ending story. We have to deal with it every time we are asked to use a test that already exists or to construct a new one. Therefore, the article aims at dealing with test validity in order to point out the different (qualitative and quantitative) aspects of validity, which have emerged from empirical research and theoretical reflections. It is thought as a critical review which can be useful both to theoretically oriented and practically inclined psychologists.     

Organizational‐Level Gender Dissimilarity and Employee Commitment

This study explores the extent to which gender dissimilarity in the workplace affects employees' commitment to their organization, using data from the British (1998) Workplace Employee Relations Survey. The results showed that the effects of organizational‐level gender dissimilarity on organizational commitment were more complex than has commonly been assumed in the literature. The relationship between organizational‐level gender dissimilarity and employee commitment was U‐shaped for women whereas it was not significant for men. The relationship was moderated by the respondents' status as measured by their level of pay. For men, the relationship between gender dissimilarity and commitment was negative for high‐paid individuals but not for low‐paid ones, while for women the U‐shaped relationship was weaker for high‐paid individuals than for low‐paid individuals.     

Can you do the wrong thing and still be right? Hypothesis testing in I(2) and near-I(2) cointegrated VARs

In this paper, we investigate the small-sample performance of LR tests on long-run coefficients in the I(2) model; we focus on a comparison between I(2) and near-I(2) data, i.e. I(1) data with a second root very close to unity, and report the results of some Monte Carlo experiments. With near-I(2) data, the finite-sample properties of the tests are (i) similar to those found with genuine I(2) data, (ii) systematically superior to those of the analogous tests constructed in the I(1) model, even if the latter is, in principle, correctly specified and the former is not. Therefore, there seems to be strong support to the idea that, in practice, modelling near-I(2) data using the I(2) model may be a good idea, despite the inherent misspecification.     

Demand chain management: an integrative approach in automotive retailing

Recent reviews of the ‘operations management’ (OM) research literature have shown a surprising little shift towards empirical methodologies from traditional modelling solution methods. In addition, there is generally a lack of empirical testing and validation of manufacturing strategies. Coupled to this fact is that empirical work is rarely carried out in an inter-disciplinary manner, with the complete combination of OM, marketing, strategy, lean thinking and accounting approaches particularly poorly researched. Fully cross-functional integrative empirical research is required to help support the understanding of the applicability of OM practices within industry. This paper explores such an integration of approaches developed within the ‘lean thinking, strategic cost management, marketing and policy deployment areas’. In order to investigate the approach a single automotive retailer is used as an instrumental case. The results of the study show that the new approach stands up well as an integrative approach that can prove highly beneficial results. However, the pilot work also identified a number of limitations that are the basis of further refinement and testing of the method.     

Latent class count models of total visitation demand: <Emphasis Type="Italic">days out hiking in the eastern Alps</Emphasis>

We report preliminary results on the investigation of the hypothesis of the existence of latent classes in the total demand for days out in a vast section of the Italian Eastern Alps. Finite mixing is informed by socioeconomic variables and it is limited to the demand portion of a hurdle model of visitation. Gradually more flexible count models are estimated moving from the Poisson to the Negative Binomial -1 and -2, to the generalized negative binomial. The implications for expected consumers surplus, predicted visitation and choke prices are discussed for a plausible 2 class model where years of experience play an important role in class membership.      

Generating the efficient frontier of a class of bicriteria generalized fractional programming

In this paper, a particular class of bicriteria maximization problems over a compact polyhedron is considered. The first component of the objective function is the ratio of powers of affine functions and the second one is linear. Several theoretical properties are provided, such as the pseudoconcavity of the first criterium of the objective function, the connectedness and compactness of both the efficient frontier and the set of efficient points. The obtained results allow us to propose a new simplex-like solution method for generating the whole efficient frontier; to better clarify the use of the suggested algorithm, several examples are described and the results of a computational test are presented.
