The purpose of this paper is to analyze the impact of the Bank of Japan's official interventions on the JPY/USD parity during the period 1992–2004. The novelty of our approach is to combine two recent advances of the empirical literature on foreign exchange interventions: (i) drawing on over-the-counter option prices to characterize more precisely the distribution of market expectations; (ii) redefining interventions in terms of events as they tend to come in clusters. Moreover, in order to deal with the features of the data (small sample size, non-standard distribution), we use bootstrap tests.We show that interventions have a significant impact on the mean expectation (the forward rate). The results are more ambiguous for variance. Additionally, we find that the effect of interventions on skewness is significant, robust to different definitions of skewness, and consistent with the direction of interventions. On the contrary, our results clearly show that kurtosis is not affected by interventions. We finally show that: (i) coordination increases effectiveness of interventions; (ii) results are not altered when controlling for other economic and political news.  相似文献

On the basis of historical data aggregated over the period 1973 to 2000, we have experimented with four different approaches to estimate the synthetic euro's equilibrium exchange rate. Using a number of competing models with the same data set, variable definitions and sample period offers the possibility to assess the uncertainty surrounding such equilibrium levels, both from an empirical (different estimates) and a theoretical viewpoint (different specifications). In this exercise, the 'Rest of the World' is proxied by the US, the UK, Japan and Switzerland, aggregated on the basis of trade weights.
We employed reduced form co–integration models, a structural VAR, a NATREX model (estimated in structural form) and the ECB's small–sized euro area wide macro–econometric model. In this order the approaches feature an increasing degree of 'structure', in the sense of the constraints based on economic theory embedded in the econometric models that were estimated. The results confirm the high likelihood for the euro having been undervalued in Q4 2000, while stressing the significant empirical and theoretical uncertainty with respect to the equilibrium exchange rate level.  相似文献

Election forecasting has become a fixture of election campaigns in a number of democracies. Structural modeling, the major approach to forecasting election results, relies on ‘fundamental’ economic and political variables to predict the incumbent’s vote share usually a few months in advance. Some political scientists contend that adding vote intention polls to these models—i.e., synthesizing ‘fundamental’ variables and polling information—can lead to important accuracy gains. In this paper, we look at the efficiency of different model specifications in predicting the Canadian federal elections from 1953 to 2015. We find that vote intention polls only allow modest accuracy gains late in the campaign. With this backdrop in mind, we then use different model specifications to make ex ante forecasts of the 2019 federal election. Our findings have a number of important implications for the forecasting discipline in Canada as they address the benefits of combining polls and ‘fundamental’ variables to predict election results; the efficiency of varying lag structures; and the issue of translating votes into seats.  相似文献

Regulators often do not regulate all firms competing in a given sector. Due to product substitutability, unregulated competitors have incentives to bribe regulated firms to have them overstate their costs and produce less, thereby softening competition. The best collusion-proof contract entails distortions both for inefficient and efficient regulated firms (distortion ‘at the top’). But a contract inducing active collusion may do better by allowing the regulator to ‘team up’ with the regulated firm to indirectly tax its competitor. The best such contract is characterized. It is such that the unregulated firm pays the regulated one to have it truthfully reveals its inefficiency. We finally compare those contracts.  相似文献

We characterize the set of communication equilibrium payoffs of any undiscounted repeated matrix-game with imperfect monitoring and complete information. For two-player games, a characterization is provided by Mertens, Sorin, and Zamir (Repeated games, Part A (1994) CORE DP 9420), mainly using Lehrer's (Math. Operations Res. (1992) 175) result for correlated equilibria. The main result of this paper is to extend this characterization to the n-player case. The proof of the characterization relies on an analogy with an auxiliary 2-player repeated game with incomplete information and imperfect monitoring. We use Kohlberg's (Int. J. Game Theory (1975) 7) result to construct explicitly a canonical communication device for each communication equilibrium payoff.  相似文献

The purpose of this study is to examine how credit rating agencies’ decisions impact the stock market using a systematic and quantitative review of existing empirical studies. Specifically, we employ a meta‐regression analysis (MRA) to investigate the extent and nature of the effect of rating agencies’ decisions on the stock market. We survey 62 studies published between 1978 and 2015. Our first finding is that the cumulative average abnormal returns calculated from this empirical literature are affected by publication bias. After controlling for publication bias, the main findings of our meta‐analysis indicate that negative rating decisions cause statistically significant negative abnormal returns. This evidence suggests an informational effect. Our results also indicate that positive rating decisions do not have a significant effect. Finally, the MRA results reveal the importance of several factors related to primary study design, as well as to the nature of the data.  相似文献

Alternative consumption schemes require the selection of producers and traders according to criteria and through processes that should make alternative values concrete. The way values turn concrete is crucial for the effectiveness of such projects. This paper investigates the ways criteria and processes are defined and their real meanings and uses through the case of associative local currencies. Drawing on the framework of proximities, it analyses local currency schemes as combining proximities (geographical and non-geographical) and selection processes set up for providers wishing to join. Selection processes may be based on a charter, an approval committee and screening criteria. The objectives of the selection, its measures in principle, the way in which it is applied as well as the practical consequences are discussed. Even when charters and formal participatory schemes for selecting providers are established, proximities appear as the keystone of selection and trust.  相似文献

This paper argues that the process of economic globalisation is to remain partial, because of its continued reliance upon the national institutions in charge of the definition and enforcement of private property rights. Emerging economies often face critical enforcement problems, but the experience of the European Single Market also suggests that, in this respect, institutional convergence remains extremely slow. Second, the globalisation process since 1990 has seen a sharp growth in private inter‐temporal contracts, exemplified by private financial transactions and by contracting on intellectual property rights; both are much more vulnerable to local institutional failures than trade in tangible goods and sovereign credits, which were the hallmark of previous phases of international liberalisation. Thus the ‘frontier’ of globalisation now makes markets more exposed to the underlying fragmentation of national property institution than before. This suggests that multilateral negotiation, as an instrument for the coordination of State institutions, will remain the backbone of international economic integration.  相似文献

Research summary : Recent research rooted in the resource‐based view of the firm suggests that resources are more likely to create value if they are effectively managed. An underlying assumption of the literature is that firms manage their resources on their own. However, many firms hire consultants to help them do so. In this study, I develop and test hypotheses regarding the impact of technical consultants on the quality of their clients' products. Using data from the Bordeaux wine industry, I find evidence that the use of technical consultants has a positive impact on relative product quality and a negative impact on the extremeness of relative product quality. Moreover, the positive impact of technical consultants on relative product quality is stronger at lower levels of relative resource quality. Managerial summary : Findings from a study in the Bordeaux wine industry indicate that the decision to hire consultants should depend on a firm's strategy. If a firm wants to improve its performance, it should hire consultants. Indeed, the “best practices” of technical consultants are generally more valuable than internally generated knowledge. If a firm wants to achieve outstanding performance, hiring consultants may not be the right decision. Because the “best practices” of technical consultants have more certain performance implications than internally generated knowledge, they decrease the likelihood of extremely low performance. However, their lack of uniqueness also decreases the likelihood of extremely high performance. Finally, the decision to hire consultants should depend on the quality of a firm's resources. Firms with low‐quality resources tend to benefit more from the “best practices” of technical consultants. Copyright © 2016 John Wiley & Sons, Ltd.  相似文献

Based on a long-term ethnographic study of a group of French boxers, this article retraces the biography of one of its members. Éric was an average boxer who never truly mastered the art of dodging his opponents. He never left the ranks of amateur boxing either, although in fact he never truly hoped he would step into the limelight reserved for the very few champions who make it. His anonymous and relentless commitment to boxing was in fact filled with a different meaning that his ethnobiography brings to light. His commitment to boxing can be better understood in light of the trials he faced in “the poor life”, a life he described as flavorless, mired in unemployment and survival delinquency. Despite his repeated defeats in the ring, for him boxing was the only part of his identity that elevated his status and set him apart from those who only had the streets to hang out on. By revealing the meaning he gave to his pugilism, Éric’s ethnobiography offers a new perspective on the links between boxing, violence, and poverty. It also paves the way for exploring the dark side of a leisure activity and its struggles that extend far beyond the ring itself.  相似文献
