Corporate social responsibility reporting: A comprehensive picture?

This study develops a content analysis framework that provides information on the comprehensiveness of corporate social responsibility (CSR) reporting, an important aspect of social and environmental accountability. Comprehensive reporting, as defined here, requires three types of information for each disclosed CSR item: (i) vision and goals, (ii) management approach, and (iii) performance indicators. The feasibility of the framework to assess the comprehensiveness of CSR reporting is demonstrated using the 2005 annual reports of a sample of publicly traded Belgian companies. The content analysis reveals a low level of comprehensive reporting. This finding complements those of prior studies on the completeness of CSR reporting and, therefore, feeds the debate regarding the extent to which CSR reporting can be considered a mechanism for discharging social and environmental accountability.

A collective,undifferentiated accounting profession: an Australian study

A study of 386 potential and current members of the accounting profession in Australia and South‐East Asia provides evidence of the importance of three attributes – brand/reputation, international recognition of qualifications and career opportunities – in the decision to join a professional accounting body. While these attributes are important, logit regression models indicate that they are not discriminatory in the choice of professional body and suggest a perception of a collective, undifferentiated accounting profession. The marketing of brand/reputation and membership benefits may be a more efficient and effective strategy in attracting members and differentiating the profession if undertaken by a combined or coordinated professional body.     

Signaling,network externalities,and subsidies

A signal may be more effective the greater the number of people who use the same signal, thereby creating a network externality and potentially generating multiple equilibria. A subsidy to the signal can increase efficiency, and the signalers may benefit from the subsidy even if they pay taxes to finance it. But people who benefit from the signal may oppose too large a subsidy, because a large subsidy could destroy the signaling value.     

Competition,transmission and bank pricing policies: Evidence from Belgian loan and deposit markets

This paper addresses the pass-through from market interest rates to retail bank interest rates. The paper advocates a heterogeneous approach and applies it to the Belgian banking market. A substantial proportion of the heterogeneity in bank pricing policies can be explained by the bank lending channel and the relative market power hypothesis. The results also suggest that the long-term pass-through is typically less than one-for-one, rejecting the completeness hypothesis. While there is no convincing evidence for asymmetry in retail rates, large deviations from equilibrium mark-ups are faster reduced than small deviations. Overall, conditions for corporate loans are more competitive compared to consumer loans. Demand and savings deposits have, by far, the most rigid prices.     

Mean–variance and mean–semivariance portfolio selection: a multivariate nonparametric approach

While univariate nonparametric estimation methods have been developed for estimating returns in mean-downside risk portfolio optimization, the problem of handling possible cross-correlations in a vector of asset returns has not been addressed in portfolio selection. We present a novel multivariate nonparametric portfolio optimization procedure using kernel-based estimators of the conditional mean and the conditional median. The method accounts for the covariance structure information from the full set of returns. We also provide two computational algorithms to implement the estimators. Via the analysis of 24 French stock market returns, we evaluate the in-sample and out-of-sample performance of both portfolio selection algorithms against optimal portfolios selected by classical and univariate nonparametric methods for three highly different time periods and different levels of expected return. By allowing for cross-correlations among returns, our results suggest that the proposed multivariate nonparametric method is a useful extension of standard univariate nonparametric portfolio selection approaches.
