Compétence et qualité des décisions de vérification*

Résumé. L'auteur étudie l'incidence de la compétence sur la qualité de la prise de décisions de vérification dans le contexte de la planification de la vérification. Contrairement aux chercheurs qui se sont, jusqu'à maintenant, penchés sur cette question, il mesure la compétence par rapport à des champs de connaissances précis. Il évalue la qualité de la prise de décisions de vérification en fonction de trois critères: la conformité aux normes de la profession, la conformité aux normes du cabinet et le degré de consensus parmi les vérificateurs. Dans l'ensemble, les résultats de l'analyse permettent de conclure que la qualité de la prise de décisions, au sens que lui donne l'auteur, est supérieure chez les vérificateurs expérimentés par rapport aux vérificateurs inexpérimentés. Plus particulièrement, il semble, en premier lieu, que les vérificateurs expérimentés comme les vérificateurs inexpérimentés possèdent un bagage de connaissances minimum et se conforment aux normes de la profession. En second lieu, les vérificateurs expérimentés se conforment davantage aux normes du cabinet, tant en ce qui a trait aux décisions relatives à la confiance à accorder au contrôle interne qu'aux décisions de corroboration, ce qui indique que les connaissances des vérificateurs expérimentés seraient plus approfondies que celles des vérificateurs inexpérimentés. Enfin, le degré de consensus chez les vérificateurs expérimentés est supérieur à celui qu'on retrouve chez les vérificateurs inexpérimentés en situation de vérification normale, bien que dans les situations plus inhabituelles, le degré de consensus soit plus faible chez les vérificateurs expérimentés.     

Breaking Collusion in Auctions through Speculation: An Experiment on CO2 Emission Permit Markets

The European Emission Trading Scheme (EU‐ETS) has chosen to adopt an auctioning procedure to initially allocate CO₂ emission permits. Free allocation of permits will become an exception for the third phase (2013–2020) and most firms will have to buy all their permits on the market or via auctions. The ability of bidders to collude is a key concern about the design of the auction format. To counter collusion, the auction can be open to bidders without compliance obligations (speculators). This paper aims at studying experimentally speculation as a collusion‐breaking device in two different auction mechanisms: the uniform‐price sealed‐bid auction and the ascending clock auction. Our results suggest that a uniform sealed‐bid auction open to speculators should be chosen from a revenue maximization point of view. In this mechanism, compliance agents adopt an aggressive strategy toward speculators. This strategy significantly increases the seller's revenue, compared to the more collusive clock auction. In the latter, on the contrary, bidders accommodate speculators, letting them buy permits in the auction and buying their necessary permits on the secondary market. However, as opening the auction to speculators deteriorates efficiency, the regulator faces a trade‐off between these two objectives.     

Where is the GE? Consumption Dynamics in DSGEs

We offer a partial equilibrium perspective on the behavior of consumption in dynamic stochastic general equilibrium (DSGE) models. We consider a benchmark dynamic general equilibrium model and show that a standard calibration implies that the real interest rate is essentially fixed. One manifestation of this feature is that, with separable preferences, the reaction of consumption to total factor productivity (TFP) shocks is flat: the random‐walk permanent income hypothesis holds almost exactly, pretty much as in a partial equilibrium consumption‐savings problem. These results help explain the prominent role of aggregate demand, and how it is achieved, in modern DSGE analysis.     

Debt Stabilizing Fiscal Rules

Unstable government debt dynamics can typically be stabilized around a certain target level of debt by adjustments in various fiscal instruments, like government spending, transfers, or taxes. This paper investigates properties of debt stabilizing rules which link the needed budgetary adjustments to the state of the economy. The paper establishes that the magnitude of the target level of long‐run debt is a key determinant of whether it is possible to find a rule of this type that can be implemented under all available fiscal instruments. Specifically, considering linear feedback rules, the paper demonstrates that there may well exist a critical target level of debt beyond which this is no longer possible. From an applied perspective, this finding is of particular relevance in the context of a monetary union with decentralized fiscal policies. Depending on the target level of debt, there might be a conflict between a common fiscal framework that tracks deficit developments as a function of the state of the economy and the unrestricted choice of fiscal policy instruments at the national level.     

Jury Decisions and Awards in Personal Injury Lawsuits Involving Foodborne Pathogens

A study of food poisoning jury verdicts in 32 states (1988–1997) revealed that plaintiffs won awards in food poisoning jury trials 31% of the time, and received a median award of $25,560. Multivariate analyses were performed to examine the effects of various factors on food poisoning jury verdicts and on the size of the award. The odds of a plaintiff victory increased if a foodborne pathogen or illness was specified, and decreased if defendants had “deep pockets”or used medical expert testimony. Illnesses involving hospitalization, death, or chronic complications received higher awards than other illnesses.     

Welfare to Well‐Being Framework for Research,Education, and Outreach

The proposed framework is intended to serve as a model for understanding the comprehensiveness of welfare assistance policies that contribute to the economic well‐being of individuals and families. The framework uses a systems approach to move thinking from a narrow focus on welfare assistance as welfare for the few to well‐being of the many. Such an approach provides a new way to understand policies and language related to welfare reform.     

A cross-cultural examination of the aetiology of attitudes towards money

Few cross-cultural studies have been conducted on the aetiology of attitudes toward money. Such research becomes more important with increased international economic exchange. This study compares attitudes towards money in Great Britain and the U.S.A. The purpose was to replicate Furnham's British study made in 1984 using the Money in the Past and Future Scale (MPFS) with an American sample to provide a cross-cultural comparison. Analysis of Variance (ANOVA) was used to determine which of the sociodemographic variables were related to respondent attitudes toward money in the past and future. Differences in the MPFS were found between the two countries. The origin or aetiology of these differences in attitudes towards money can be, in part, attributed to cultural differences that begin in the context of the family and are reinforced by society.
