Examples of unit tax superiority for a price-discriminating monopolist

This paper compares the welfare effects of per-unit and ad valorem taxes in four pervasive price discrimination schemes: quantity discounts, two-part tariffs, bundling, and package size price discrimination. The paper shows by example that per-unit taxes may welfare dominate ad valorem tariffs in a market with a monopoly that maximizes profits by engaging in second-degree price discrimination.     

Cross‐selling in the US home video industry

We identify significant cross‐selling effects in the home video industry: a 10% increase in the demand for a studio's old titles leads to a 4.7% increase in new title sales. We argue this is due to supply‐side effects: studios with strong titles are better able to “push” other titles through retailers; and the latter “push” these additional supplies to consumers by means of lower prices and/or heavier advertising. Our strategy for identifying causality is based on “star power” effects: increases in old movie demand caused by recent success of movies with a similar cast and/or director.     

‘Fair Value’ of Core Deposits in the EU version of IFRS: A Critical Review

The paper presents seven impacts of the introduction of core deposits models in credit institutions into International Financial Reporting Standards (IFRS). First, the equity of the credit institution will be higher for the core deposit premium adjusted for deferred tax. Second, the models make it possible for some financial instruments (e.g., interest rate swaps where the credit institution receives fixed payments and pays floating payments) to be designated as hedging instruments. Third, there is lower comparability of financial statements, as no standard business model of core deposits exists. Fourth, the models can be understood at the next step of relaxing of prudence (conservatism) and neutrality of IFRS. Fifth, there is inconsistency in the core deposit definition. By definition, these deposits should be stable for a long (infinite) period. Then, the present value of core deposits should be zero which is flawed. Sixth, there is inconsistency in the interest rate risk definition. Seventh, according to available information, the core deposits models have not been introduced into accounting in any national generally accepted accounting principles (GAAP) such as US GAAP. Thus the fair value of core deposits should be equal to the nominal value of these deposits. The accounting should not reflect the core deposits models. The carve‐out in the European version of IFRS should be removed.     

Consumers’ avoidance of information on red meat risks: information exposure effects on attitudes and perceived knowledge

In accordance with cognitive dissonance theory, individuals generally avoid information that is not consistent with their cognitions, to avoid psychological discomfort associated with tensions arising from contradictory beliefs. Information avoidance may thus make risk communication less successful. To address this, we presented information on red meat risks to red meat consumers. To explore information exposure effects, attitudes toward red meat and perceived knowledge of red meat risks were measured before, immediately after, and two weeks after exposure. We expected information avoidance of red meat risks to be: positively related to (1) study discontentment; and (2) positive attitudes toward red meat; and negatively related to (3) information seeking on red meat risks; and (4) systematic and heuristic processing of information. In addition, following exposure to the risk information, we expected that (5) individuals who scored high in avoidance of red meat risks information to change their attitudes and perceived risk knowledge less than individuals who scored low in avoidance. Results were in line with the first three expectations. Support for the fourth was partial insofar as this was only confirmed regarding systematic processing. The final prediction was not confirmed; individuals who scored high in avoidance decreased the positivity of their attitudes and increased their perceived knowledge in a similar fashion to those who scored low in avoidance. These changes stood over the two-week follow-up period. Results are discussed in accordance with cognitive dissonance theory, with the possible use of suppression strategies, and with the corresponding implications for risk communication practice.     

Is it all about awareness? The normalization of coastal risk

Coastal risk is already high in several parts of the world and is expected to be amplified by climate change, which makes it necessary to outline effective risk management strategies. Risk managers assume that increasing awareness of coastal risk is the key to public support and endorsement of risk management strategies – an assumption that underlies a common worldview on the public understanding of science, which has been named the deficit model. We argue that the effects of awareness are not as straightforward. In particular, awareness of coastal hazards might not lead to more technically accurate risk perceptions. Based on research on risk perception normalization, we explored the hypothesis that coastal risk awareness reduces coastal risk perception – in particular the perceived likelihood of occurrence of coastal hazards – through its effect on reliance on protective measures to prevent risk. Individuals can rely on protective measures, even when those are not effective, as a positive illusion to reduce risk perception. This effect might be stronger for higher probability hazards and for permanent residents of costal zones. Data from 410 individuals living in coastal zones corroborated most of our expectations. Global results demonstrated a risk normalization effect mediated by reliance on current measures. Additional analyses made clear that this effect occurred in 2 of the 5 high-probability hazards (flood and storm), and not in the low-probability hazard (tsunami). Normalization might be more likely among high-probability hazards which entail catastrophic and immediate impacts. This effect was also found among permanent residents, but not among temporary residents. Results imply that coastal risk management might benefit from (a) taking risk perception normalization effects into account, (b) tailoring strategies for permanent and temporary residents and (c) promoting a higher public engagement, which would facilitate a more adaptive and effective coping with coastal risk than the use of positive illusions.     

Profitability in Banks Affiliated to a Business Group: Evidence from Mexico

In certain institutional contexts, where there are business groups, banks affiliated to these business networks are faced by incentives that might condition their profitability. The objective of this article is to test whether there is a difference between the performance of affiliated banks and that of banks not affiliated to groups, in the context of an emerging market. In particular, a study is made of the case of Mexico in the period 2007–11. Findings suggest that banks affiliated to business groups show less profitability than non-affiliated banks, which may be a consequence of the provision of loans in an internal capital market.     

Disentangling the role of variance and covariance information in portfolio selection problems

The covariation among financial asset returns is often a key ingredient used in the construction of optimal portfolios. Estimating covariances from data, however, is challenging due to the potential influence of estimation error, specially in high-dimensional problems, which can impact negatively the performance of the resulting portfolios. We address this question by putting forward a simple approach to disentangle the role of variance and covariance information in the case of mean-variance efficient portfolios. Specifically, mean-variance portfolios can be represented as a two-fund rule: one fund is a fully invested portfolio that depends on diagonal covariance elements, whereas the other is a long-short, self financed portfolio associated with the presence of non-zero off-diagonal covariance elements. We characterize the contribution of each of these two components to the overall performance in terms of out-of-sample returns, risk, risk-adjusted returns and turnover. Finally, we provide an empirical illustration of the proposed portfolio decomposition using both simulated and real market data.     

When Do Employees Cyberloaf? An Interactionist Perspective Examining Personality,Justice, and Empowerment

Cyberloafing—using the Internet for non‐work‐related activities—is a prevalent counterproductive work behavior in the workplace, but researchers have not yet paid sufficient attention to this issue, especially related to the role of personality in cyberloafing. Recognizing such a research gap, and using a trait activation theory framework, this study examines whether conscientiousness and emotional stability negatively relate to cyberloafing. We further investigate how organizational justice perceptions and psychological empowerment moderate the negative relationship between these personality traits and cyberloafing. Based on a sample of 247 employees, we find that those high in conscientiousness cyberloaf less when they perceive greater levels of organizational justice. In addition, highly conscientious individuals cyberloaf less when they have low, rather than high, levels of psychological empowerment. Implications for research and practice as well as future research directions are discussed. © 2015 Wiley Periodicals, Inc.     

Leaders and Laggards in Environmental Innovation: An Empirical Analysis of SMEs in Europe

The main purpose of this article is studying the factors influencing eco‐innovative intensity in the European SMEs. Building upon the 'innovation triangle model', business competences, environmental orientation and network involvement are considered as the main determinants of 'greenness' of innovation in a sample of 3852 SMEs. Four categories of eco‐innovators (leaders, followers, loungers and laggards) are identified, and their profiles/driving factors are described using a generalized ordinal logistic model. Our results confirm that the increasing demand for green products and the adoption of eco‐organizational innovation affect positively the level of environmental innovation, while technological lock‐ins have the opposite effect across all categories. Neither leaders nor laggards are influenced by environmental policies. Small firms and those who give importance to financial constraints tend not to achieve upper categories, while valuing technological capabilities, market power and networks are crucial determinants of being in upper categories of eco‐innovation intensity.

Knowledge management practices and absorptive capacity in small and medium‐sized enterprises: is there really a linkage?

Small and medium‐sized enterprises (SMEs) are more vulnerable to globalization and rapid technological change due to their scarcity of resources. SMEs' absorptive capacity allows them to access knowledge and plays a key role in their ability to explore and exploit opportunities in their environment. Therefore, this study aims to identify and categorize knowledge management practices which SMEs can adopt to develop absorptive capacity. From a population of 4,534 Portuguese SMEs, 260 usable completed questionnaires were returned. We concluded that Portuguese SMEs are engaged in knowledge management practices, through collaboration with business partners, favoring learning processes based on experience, knowledge transfer to employees and knowledge absorption by employees, reflecting the importance given by SMEs to the tacit nature of knowledge which helps them in efficiency improvements, strategic adaptation, and the launch of new products and services. Our study contributes to advancing theory in the fields of knowledge management and absorptive capacity. We combine and extend previous research which allows us to reconcile the sometimes contradictory findings concerning knowledge management practices which SMEs can adopt to reinforce absorptive capacity. Some theoretical and practical implications are also presented.
