Bank Monitoring and Environmental Risk

Abstract:  Loan announcement effects for 152 Canadian companies are examined to investigate the efficiency of monitoring by banks facing lender environmental liability. Market reaction to the announcement of bank debt to 'environmental' firms is more positive and significant than for 'non-environmental' firms and, for firms in industries with a higher likelihood of experiencing spill events, is more positive and significant, reinforcing earlier results that establish a relationship between specific loan/borrower characteristics and announcement period excess returns and providing further evidence on the 'uniqueness' of bank loans by demonstrating the superior ability of banks to monitor corporate borrowers exposed to environmental liability.     

Oppression and resistance: the powerless and the future

Relations between rich and poor (across and within countries) appeared in some questions in Images; there were clear differences between what the powerful and the powerless hoped and expected from the future. This is compared with what actually happened and a deeper analysis is made of ‘power’ as an organizing concept. It turned out that the pessimism associated with powerlessness tended to make better predictions.     

Optimal failure rates and penalty-bonus policies in the offshore petroleum sector

We characterize optimal time profiles of risk-reducing expenditures and wreck probabilities for petroleum platforms. The input to our analysis is the development of wreck cost, direct and imputed. Particular attention is paid to the question of how private companies deviating from socially optimal standards may be induced to comply with such standards by means of a) a time-variant penalty, b) a no-wreck bonus and c) a time-invariant penalty.     

Consumer safety in Greece: An analysis of the Consumer Protection Act 1991

In September 1991 the Greek Consumer Protection Act No. 1961 was enacted. Chapter 2 of this Act establishes a legal framework for product safety. This framework has the dual aim of securing deregulation in the Greek market while maintaining effective consumer protection. This paper analyses the main features of this framework and demonstrates its inadequacies. It also investigates the extent to which these inadequacies could jeopardise an effective protection of consumers' interests. The paper concludes by emphasising that effective protection of consumers can only be achieved by supporting the general safety requirement with adequate accident-surveillance systems, mechanisms for investigation of risks, unambiguous risk-assessment criteria, creation of a comprehensive set of supporting standards that offer a high level of protection, effective control of the safety of products by the authorities, and real possibilities for consumer organisations to participate in the whole process.

Zusammenfassung Die Sicherheit des Verbrauchers in Griechenland: eine Analyse des Verbraucherschutzgesetzes von 1991 Im September 1991 trat das griechische Verbraucherschutzgesetz in Kraft. Kapitel 2 des Gesetzes führt einen rechtlichen Rahmen für die Sicherheit von Produkten ein. Dieser Rahmen verfolgt das Ziel der Deregulierung auf dem griechischen Markt bei zugleich wirksamem Verbraucherschutz. Der Beitrag analysiert die wesentlichen Aspekte dieses Rahmens und stellt seine Schwächen dar. Er prüft, inwieweit diese Schwächen einem wirksamen Verbraucherschutz entgegenstehen können, und hebt hervor, da\ wirksamer Verbraucherschutz nur durch Stärkung der allgemeinen Sicherheitsbestimmungen erreicht werden kann. Dafür sind erforderlich ein angemessenes Unfallüberwachungssystem, Regelungen für die Untersuchung von Risiken, eindeutige Kriterien für die Bewertung von Risiken, die Entwicklung umfassender Kriterien zur Gewährleistung eines hohen Schutzniveaus, die wirksame Kontrolle der Produktsicherheit durch die Behörden, sowie für die Verbraucherorganisationen die faktische Mitwirkungsmöglichkeit an der gesamten Entwicklung.

Using an approximate kiefer-weiss solution for testing insect population densities

Summary A sequential testing procedure called 2-SPRT for the meanμ of the negative binomial distribution with known exponentk is presented. For any fixedμ ₀(μ ₁<μ ₀<μ ₂), the 2-SPRT provides an asymptotic solution to the modified Kiefer-Weiss problem. Determination ofμ ₀ such that the test provides an approximate solution to the Kiefer-Weiss problem is described. The behavior of the 2-SPRT and the Sequential Probability Ratio Test is investigated using Monte Carlo methods. The error probabilities and the average sample numbers are compared. All the computations were carried out on the Alabama Supercomputer.
