This study provides a survey of recent advances in the literature on proposed African monetary unions. The survey comprises about 70 empirical papers published during the past 15 years. Four main strands are discussed individually and collectively. They comprise the proposed: (i) West African Monetary Zone (WAMZ), (ii) East African Monetary Union (EAMU), (iii) Southern African Monetary Union (SAMU) and (iv) African Monetary Union (AMU). We observe a number of issues with establishing the feasibility and/or desirability of potential monetary unions, inter alia, they are variations in: choice of variables, empirical strategies, sampled countries and considered periodicities. We address this ambiguity by reviewing studies with scenarios that are consistent with Hegelian dialectics and establish selective expansion as the predominant mode of monetary integration. Some proponents make cases for strong pegs and institutions as viable alternatives to currency unions. Using cluster analysis, disaggregating panels into sub-samples and distinguishing shocks from responses in the examination of business cycle synchronisation provide more subtle policy implications. We caution that for inquiries using the same theoretical underpinnings, variables and methods just by modifying the scope/context and periodicity may only contribute to increasing the number of conflicting findings. Authors should place more emphasis on new perspectives and approaches based on caveats of, and lessons from the European Monetary Union (EMU) and CFA zones.  相似文献

This paper aims to investigate the influence of organizational structure on service innovativeness by testing the moderating roles of learning orientation and inter-functional coordination. This helps to understand how organic structure influences service innovativeness when it is effectively leveraged with favorable organizational factors. Data were collected from 178 hotel managers and executives in Japan and moderated regression analysis was performed to analyze the data. Findings of the study suggest that higher levels of service innovativeness are positively related to higher levels of hotel business performance. In addition, organic structure makes a positive influence on service innovativeness and an increase in the levels of learning orientation boost the effectiveness of organic structure on service innovativeness. Moreover, the positive association between organic structure and service innovativeness become stronger when all firm’s functions make an attempt to cooperate and contribute to disseminating customers and competitors’ information in the hotels. These findings contribute to understanding how hotel service innovation is affected by service innovativeness, organizational structure, learning orientation and inter-functional coordination.  相似文献

This paper aims to analyse the feasibility of policy coordination among the ASEAN-5 economies. This is done by determining whether they experience symmetric responses to common shocks. Given that the problem of dimensionality plagues large-scale macroeconomic modelling, a Global VAR model by Pesaran, Schuermann, and Weiner (2004) and Dees, Mauro, Pesaran, and Smith (2007) is used. The results in this paper provide some weak evidence of symmetric responses to the common (global) shocks of interest: a US monetary policy shock, a US output shock, a Chinese output shock; an oil price shock. Shocks from the US produced the most symmetric responses. The lack of symmetry in some cases has implications for further policy coordination. Since migrant remittances could provide an adjustment mechanism, further labour market integration is needed as it currently lags behind trade and financial integration in the region.  相似文献

This paper discusses how small technology-based firms (STBFs) effectively manage vertical alliances by choosing proper alliance structures to both manage challenges and pursue higher performance. We consider the main challenges of STBFs’ vertical alliances as opportunistic risk and coordination concern between partners, and derive four types of vertical alliance portfolios with different extents of risk and return based on the relational perspective. We then examine the impact of each portfolio on performance and the moderating effect of STBFs’ age and technological capability. The results show the portfolio focusing on bilateral alliances is not helpful for STBFs, while the others are useful. The portfolio focusing on unilateral alliances promises young firms better performance, while hybrid portfolios of unilateral and bilateral alliances are more helpful for older STBFs. In hybrid portfolios, bilateral alliance in the upstream is beneficial to specific technology-focused firms, while bilateral alliance in the downstream is recommended to STBFs whose technology covers a wider range.  相似文献

We examine whether stress tests distort banks' risk‐taking decisions. We study a model in which a regulator may choose to rescue banks in the event of concurrent bank failures. Our analysis reveals a novel coordination role of stress tests. Disclosure of stress‐test results informs banks of the failure likelihood of other banks, which can reduce welfare by facilitating banks' coordination in risk‐taking. However, conducting stress tests also enables the regulator to more effectively intervene banks, coordinating them preemptively into taking lower risks. We find that, if the regulator has a strong incentive to bail out, stress tests improve welfare, whereas if the regulator's incentive to bail out is weak, stress tests impair welfare.  相似文献

Globally, built-up development is taking place at unprecedented rates. To mitigate and limit its effects, recent scientific and spatial planning communities call for built-up management to be addressed on broader scales, from regional to national, and coordinated with multiple policy domains. In this paper, we aimed to analyze the evolution and impact of Romania’s national policies on built-up management during the entire period from the fall of the communist regime to the present. The new perspective offered by our study concerns the use of spatiotemporal built-up development assessment with policy analysis and visualization. Moreover, policies and built-up land changes are addressed in direct relationship with major political events and global economic influences. Our findings reveal that policies were influenced by the communist legacy, accession to the EU and the global economic crisis. Most effective were the policies adopted during the pre-EU accession period and after the economic crisis. The strongest impact on patterns of development came from policies in the domains of transportation, regional development, public administration and the environment.  相似文献

Multichannel retailing is a widely adopted strategy in the fashion industry. Companies in this industry find it a source of competitive advantage to invest in reverse logistics infrastructure. However, limited empirical studies investigate the enablers of the relationship quality between the retailers and their reverse logistics service providers. This study quantifies the impact of reverse logistics process coordination between retailers and logistics service providers on relationship quality. Moreover, it tests the mediating role of reverse logistics service quality and the moderating role of conflict frequency in this relationship. Data were collected through a survey using a purposive sample of 241 retail store managers from the fashion retail industry of Pakistan. For this purpose, a self-administered questionnaire was developed using a five-point Likert Scale to gauge the responses. Conditional process analysis was used to evaluate the moderated mediation model. The findings showed a significant positive impact of reverse logistics process coordination on the relationship quality with a logistics service provider, a significant positive mediation effect of reverse logistics service quality, and a significant moderation effect of conflict frequency on the indirect relationship. However, conflict frequency, contrary to the hypothesis in the study, strengthened the indirect relationship. Furthermore, the moderation effect of conflict frequency on the direct relationship was insignificant. This study will help managers better understand the best practices leading to effective management of reverse logistics processes, particularly product returns.  相似文献

The coordinated response to extreme events is critical as illustrated by recent disasters in Haiti and Japan. As a way for coordinated provision of international humanitarian assistance to disaster-hit countries, the Office for the Coordination of Humanitarian Affairs (OCHA) developed cluster coordination model (CCM). With content analysis and network analysis of OCHA situation reports, this study checked four premises regarding activation of CCM, interaction between national and international actors, roles of proximity country, and level of cluster coordination. This study found that there were meaningful variations in implementing the CCM for 2010 Haiti and 2011 Japan disasters. From the analyses, we found that the current CCM may be vulnerable to black swan disasters; thus, extensive and active estimation of national disaster management capacities should be conducted to prevent collapse of national disaster management system. However, the reconciliation of state sovereignty and international humanitarian assistance also should be considered.  相似文献

通过对自然权利相关概念的分析与界定,明确自然权利的提出绝对不是没有现实基础的单纯思辩,而是有一定实际基础的.它的现实基础讲起来很简单,日益恶化的生态危机让人的生存问题开始严峻起来了,一方面人们开始重视人与自然之间的关系问题,开始思索人在自然当中的角色定位问题;另一方面是人与自然之间的冲突问题,即自然权利问题.要解决自然权利的问题,建立人与自然的协调发展,实现人类与自然界关系的全面、协调关系是人类生存与发展的必经之路.  相似文献

Knoblock and Korf have determined that abstraction can reduce search at a single agent from exponential to linear complexity (Knoblock 1991; Korf 1987). We extend their results by showing how concurrent problem solving among multiple agents using abstraction can further reduce search to logarithmic complexity. We empirically validate our formal analysis by showing that it correctly predicts performance for the Towers of Hanoi problem (which meets all of the assumptions of the analysis). Furthermore, a powerful form of abstraction for large multiagent systems is to group agents into teams, and teams of agents into larger teams, to form an organizational pyramid. We apply our analysis to such an organization of agents and demonstrate the results in a delivery task domain. Our predictions about abstraction's benefits can also be met in this more realistic domain, even though assumptions made in our analysis are violated. Our analytical results thus hold the promise for explaining in general terms many experimental observations made in specific distributed AI systems, and we demonstrate this ability with examples from prior research.This research has been sponsored, in part, by the National Science Foundation under grants IRI-9015423 and IRI-9010645, by the University of Michigan Rackham Graduate School, and by a Bell Northern Research Postgraduate Award.  相似文献
