RISK MEASURES: RATIONALITY AND DIVERSIFICATION

When there is uncertainty about interest rates (typically due to either illiquidity or defaultability of zero coupon bonds) the cash‐additivity assumption on risk measures becomes problematic. When this assumption is weakened, to cash‐subadditivity for example, the equivalence between convexity and the diversification principle no longer holds. In fact, this principle only implies (and it is implied by) quasiconvexity. For this reason, in this paper quasiconvex risk measures are studied. We provide a dual characterization of quasiconvex cash‐subadditive risk measures and we establish necessary and sufficient conditions for their law invariance. As a byproduct, we obtain an alternative characterization of the actuarial mean value premium principle.     

Short reports

In this study, we assessed the epidemiological patterns of suicide terrorism in the civilian population of Pakistan. Information about suicide terrorism-related events, deaths and injuries was extracted from the South-Asian Terrorism Portal (SATP) for the period from 2002 to October 2009. Of 198 events, civilians were involved in 194 events. Civilians accounted for 74.1% (N = 2017) of those who died and 93.8% (N = 6129) of those who were injured. In nine districts, mortality rates were more than one death per 100,000 inhabitants per year. The yearly trend showed a shift of attack targets from foreigners and sectarian targets in 2002–2005 to security forces or general public in 2006–2009. Attacks on public installations (mosques) or political gatherings resulted in a significantly greater (P ≤ 0.02) number of deaths (22 vs. 8) and injuries (59 vs. 24) per event compared with security installations. These results show that prevention might focus on political negotiation with armed groups and that appropriate measures should be taken to protect mosques and political gatherings.     

The Role of Stakeholders in Sustainability Reporting Assurance

The main purpose of this exploratory analysis is to understand whether, based on evidence gathered from international best practices selected among corporations which adopt the Global Reporting Initiative guidelines in sustainability reporting (SR), stakeholders are significantly consulted and involved—as international literature would indicate—by assurance providers, during assurance processes of SR. We aim at verifying if this practice—known as stakeholder assurance—is in fact widespread in SR assurance by carrying out empirical research, through content analysis, into a sample of 161 assurance statements of international corporations, in order to test characteristics of any stakeholder assurance implemented.     

Dividends, Values and Agency Costs in REITs

This study examines the market value of REIT dividends conditional on transparency of operating structure and effectiveness of boards. Results suggest that total, mandatory and discretionary dividends are valued by the market. Consistent with agency cost theory, results provide some evidence that discretionary dividends paid by REITs with greater principal-agent conflicts have greater market value. Specific results suggest an increased value of excess dividends paid by firms with more complex organizational structures (UPREITs) and, to some degree, less independent boards. This evidence implies the equity market recognizes REITs’ substitution of discretionary dividends for stronger governance.     

Tourist accommodation price setting in Australian strata titled properties

Strata title units (dwelling complexes in which individual units are owned by small investors) represent the vast bulk of Australian self-catering tourism units. In many areas, such as Australia's Gold Coast, strata title owned properties have overtaken hotels as the most popular form of tourist accommodation (Warnken, J., Russell, R., Faulkner, B., 2003. Condominium developments in maturing destinations: potentials and problems of long term sustainability. Tourism Management 24, 155–168).     

Gebrauchsanleitung für Expertenstandards

Probleme bei der Implementierung l?sen - Trotz der zunehmenden Akzeptanz von Expertenstandards im Pflegealltag zeigen sich bei der Implementierung immer noch deutliche Probleme. In den meisten station?ren und ambulanten Pflegeeinrichtungen sind daher die sieben bisher vom DNQP ver?ffentlichten Expertenstandards nur teilweise umgesetzt.     

Rating model arbitrage in CDO markets: An empirical analysis

We analyze whether information asymmetry between issuers and investors leads to rating model arbitrage in Collateralized Debt Obligation markets. Rating model arbitrage is defined as the issuer's deliberate capitalization of information asymmetry at the investor's cost on the basis of different rating processes. Using data from CDO transactions grouped by both rating agencies and underlying rating methodologies, we test for homogeneity of characteristic transaction features within the group and heterogeneity between the different groups. We find that the hypothesis stating non-existence of rating model arbitrage on the basis of information asymmetry does not hold as individual patterns of transaction characteristics within each group could be identified.
