Multiple safety net regulators and agency problems in the EU: is Prompt Corrective Action a partial solution?
Prompt Corrective Action (PCA) provides a more efficient mechanism for dealing with problem banks operating in more than one European country. In a PCA framework, a bank’s losses are likely to be substantially reduced. This reduction in the losses to deposit insurance and governments will improve the problem of allocating those losses across the various insurance schemes and make it less likely that any deposit insurer will renege on its obligations in a cross-border banking crisis. This paper explores the institutional changes needed in Europe if PCA is to be effective in resolving the cross-border agency problems that arise in supervising and resolving cross-border banking groups. The paper identifies these changes starting with enhancements in the availability to prudential supervisors of information on banking groups’ financial condition. Next, the paper considers collective decision-making by prudential supervisors with authority to make discretionary decisions within the PCA framework as soon as a bank of a cross-border banking group falls below the minimum capital standard. Finally, the paper analyses the coordination measures that should be implemented if PCA requires the bank to be resolved.banking supervision; European Union; Prompt Corrective Action
Multiple safety net regulators and agency problems in the European Union: Is prompt corrective action partly the solution?
This paper discusses the institutional changes needed in Europe if prompt corrective action (PCA) is to be effective in supervising and resolving cross-border banking groups. The paper identifies these changes starting with enhancements in the availability of information on banking groups’ financial condition to prudential supervisors. Next, the paper considers the collective decision making by prudential supervisors with authority to make discretionary decisions within the PCA framework as soon as a bank in a cross-border banking group falls below the minimum capital standard. Finally, the paper analyzes the coordination measures that should be implemented if PCA requires the bank to be resolved.
Public Perceptions of the Dioxin Crisis in Irish Pork
In early December 2008, a global recall of Irish pork was initiated as a result of a subset of the national pork output being contaminated with dioxin. In this study, members of a panel from an internet-based longitudinal monitor of public opinion on food and health, was used to assess public perceptions about the dioxin incident in late December. A larger proportion of respondents reported that that there was a 'very high' health risk from pork (8.6 %) than any other food of animal origin. The risk posed to human health from dioxins was considered to be relatively high compared to a broad range of potential food and non-food risks. The majority of respondents (70.5 %) accepted that the way in which the authorities managed the crisis was 'adequate' or 'very efficient'. These findings should be considered in light of the following facts: the European Food Safety Authority and the Irish authorities announced that there was no risk to human health from the dioxins in pork, there was extensive media attention about the dioxin incident, and the Irish Government had to introduce a 200 million euro compensation package for the Irish pork industry which was funded by the Irish taxpayer.food risk, dioxins, consumer risk perception
Model of Transcriptional Activation by MarA in Escherichia coli
We have developed a mathematical model of transcriptional activation by MarA
in Escherichia coli, and used the model to analyze measurements of
MarA-dependent activity of the marRAB, sodA, and micF promoters in mar-rob-
cells. The model rationalizes an unexpected poor correlation between the
mid-point of in vivo promoter activity profiles and in vitro equilibrium
constants for MarA binding to promoter sequences. Analysis of the promoter
activity data using the model yielded the following predictions regarding
activation mechanisms: (1) MarA activation of the marRAB, sodA, and micF
promoters involves a net acceleration of the kinetics of transitions after RNA
polymerase binding, up to and including promoter escape and message elongation;
(2) RNA polymerase binds to these promoters with nearly unit occupancy in the
absence of MarA, making recruitment of polymerase an insignificant factor in
activation of these promoters; and (3) instead of recruitment, activation of
the micF promoter might involve a repulsion of polymerase combined with a large
acceleration of the kinetics of polymerase activity. These predictions are
consistent with published chromatin immunoprecipitation assays of interactions
between polymerase and the E. coli chromosome. A lack of recruitment in
transcriptional activation represents an exception to the textbook description
of activation of bacterial sigma-70 promoters. However, use of accelerated
polymerase kinetics instead of recruitment might confer a competitive advantage
to E. coli by decreasing latency in gene regulation.Comment: 30 pages, 2 figure
