We use several U.S. and euro‐area surveys of professional forecasters to estimate a dynamic factor model of inflation featuring time‐varying uncertainty. We obtain survey‐consistent distributions of future inflation at any horizon, both in the U.S. and the euro area. Equipped with this model, we propose a novel measure of the anchoring of inflation expectations that accounts for inflation uncertainty. Our results suggest that following the Great Recession, inflation anchoring improved in the United States, while mild de‐anchoring occurred in the euro area. As of our sample end, both areas appear to be almost equally anchored. 相似文献

This paper focuses on the development of a theoretical scheme describing the transformation of primary incomes into end consumption and savings in the Russian economy. This scheme is basically a system of interrelated tables reflecting the distribution of primary incomes across the institutional sectors and their further reallocation and use. The scheme makes allowances for the specific features of the Russian economy and existing statistics. In terms of methodology, it is coordinated with the interindustry balance in current buyer prices and, from the theoretical standpoint, describes the connection between Quadrant II and Quadrant III of the balance. Therefore, the proposed system of tables is treated in the paper as Quadrant IV of the interindustry balance. The theoretical scheme is used by the authors as a necessary basis for constructing an empirical model of the relationship between value added and end product, which will be published in the next issue of this journal. 相似文献
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. 相似文献
The general design for the real-time electricity market presented in this paper optimizes and prices both real and reactive
power simultaneously in an AC setting, where all assets—generation, load and transmission—are allowed to bid and are financially
settled at the locational price times energy consumed or produced. The result is that transmission lines are compensated for
both capacity and admittance, providing incentives for efficient operation of transmission-related assets such as FACTS devices,
if price-taking behavior is assumed. Losses are incorporated into the design and become an operating cost for transmission.
The market design is shown to be revenue neutral and, under some assumptions, nonconfiscatory.

We analyze how the market processes a signaling event by studying a sample of self-tender offers, events often viewed as signals
of firm value. By examining changes in the degree of informed trading, we find asymmetric information costs fall at announcement,
remain low throughout the event, and increase at offer expiration. By one month following expiration, informed trading returns
to a level not significantly different from that prior to the offer. Higher risk firms have significantly larger declines
in information asymmetry during the offer. Increases in information asymmetry persist one month following expiration for firms
with lower pre-offer informed trading. (JEL G14, G32) 相似文献
Background: Validation of overall survival (OS) extrapolations of immune-checkpoint inhibitors (ICIs) during the National Institute for Health and Care Excellence (NICE) Single Technology Assessment (STA) process is limited due to data still maturing at the time of submission. Inaccurate extrapolation may lead to inappropriate decision-making. The availability of more mature trial data facilitates a retrospective analysis of the plausibility and validity of initial extrapolations. This study compares these extrapolations to subsequently available longer-term data.
Methods: A systematic search of completed NICE appraisals of ICIs from March 2000 to December 2017 was performed. A targeted search was also undertaken to procure published OS data from the pivotal clinical trials for each identified STA made available post-submission to NICE. Initial Kaplan-Meier curves and associated extrapolations from NICE documentation were extracted to compare the accuracy of OS projections versus the most mature data.
Results: The review identified 11 STAs, of which 10 provided OS data upon submission to NICE. The extrapolations undertaken considered parametric or piecewise survival models. Additional data cut-offs provided a mean of 18 months of OS beyond the end of the original data. Initial extrapolations typically under-estimated OS from the most mature data cut-off by 0.4–2.7%, depending on the choice of assessment method and use of the manufacturer- or ERG-preferred extrapolation.
Conclusion: Long-term extrapolation of OS is required for NICE STAs based on initial immature OS data. The results of this study demonstrate that the initial OS extrapolations employed by manufacturers and ERGs generally predicted OS reasonably well when compared to more mature data (when available), although on average they appeared to underestimate OS. This review and validation shows that, while the choice of OS extrapolation is uncertain, the methods adopted are generally aligned with later-published follow-up data and appear appropriate for informing HTA decisions. 相似文献
