This study assesses the relative performance of Greek equity funds employing a non-parametric method, namely Data Envelopment Analysis (DEA). Specifically, we evaluate the funds’ total productivity change using the DEA-based Malmquist Index. Our results reveal significant losses in funds’ productivity for the period of 2003–2009, which calls for the attention of domestic policy makers and market regulators. Significant implications for the investors’ fund selection process arise from our analysis since we are able to identify potential sources of operational inefficiencies. Employing a panel logit model we document a significant negative relationship between the probability of being efficient and funds’ size, a finding which may be related to the microstructure of the domestic stock market. Furthermore, we provide evidence against the notion of funds’ mean-variance efficiency.  相似文献

ABSTRACT

Portugal and Spain have reformed their national standards to adapt them to the International Public Sector Accounting Standards (IPSAS). This paper explains the process of implementing the IPSAS for consolidated reporting in the two countries and the advantages and disadvantages which have emerged. The results highlight the role of the IPSAS in improving the quality and use of consolidated financial statements (CFS) and will be of interest to other countries that are intending to implement the IPSAS.  相似文献

The paper studies salient features of systemic risk in a sample of 22 European (EU and non-EU) countries during January 2010–March 2016. Building on a novel dataset and conducting an empirical horse race, we determine pivotal systemic risk measures for the sample countries. SRISK and volatility indicator tend to lead other metrics, followed by leverage. In contrast to the conventional wisdom, composite systemic risk measures aggregated with the aid of principal and independent component analysis perform worse. The leading systemic risk measures exhibit a high degree of connectedness. The VIX index, TED spread, the Composite Index of Systemic Stress (CISS) and long-term interest rates underlie their dynamics. Two clusters within the sample are identified, with CISS and long-term interest rates being crucial to distinguish between them. There is only scarce evidence for causal linkages between systemic risk and industrial production in the sample countries, based on the concurring results of standard and nonparametric Granger causality tests.  相似文献

Comovement,information production,and the business cycle   总被引:1,自引:0,他引:1  
Recent theoretical research suggests that information production is a positive externality of aggregate economic activity (Veldkamp, 2005). Both the quantity and quality of information increase during periods of economic expansion and decrease during periods of contraction. Based on this insight, we hypothesize and confirm that time-varying information production drives the comovement patterns observed in stock returns. We examine stock return comovement in 36 countries from 1980 to 2007 and show that, consistent with the theory, comovement patterns are countercyclical; that is, when information production is high (low), comovement is low (high). We also find that the relation between comovement and the business cycle is stronger in countries that experience large intertemporal swings in information production. Finally, we show that the relation between business cycle and comovement is stronger in poor countries, countries with less developed financial markets, and countries with weaker accounting and transparency standards. These results suggest that financial development and transparency are conducive to a steady flow of financial information over the business cycle.  相似文献

Capital structure,equity ownership and firm performance   总被引:1,自引:0,他引:1  
This paper investigates the relationship between capital structure, ownership structure and firm performance using a sample of French manufacturing firms. We employ non-parametric data envelopment analysis (DEA) methods to empirically construct the industry’s ‘best practice’ frontier and measure firm efficiency as the distance from that frontier. Using these performance measures we examine if more efficient firms choose more or less debt in their capital structure. We summarize the contrasting effects of efficiency on capital structure in terms of two competing hypotheses: the efficiency-risk and franchise-value hypotheses. Using quantile regressions we test the effect of efficiency on leverage and thus the empirical validity of the two competing hypotheses across different capital structure choices. We also test the direct relationship from leverage to efficiency stipulated by the Jensen and Meckling (1976) agency cost model. Throughout this analysis we consider the role of ownership structure and type on capital structure and firm performance.  相似文献

Interorganizational new product development (NPD) teams with business customers are rapidly becoming more prevalent; yet the drivers of such cooperations at the team level remain unclear to practitioners and researchers alike. This study proposes an input–process–output model in which various characteristics of interorganizational teams affect NPD team effectiveness through the mediating construct of NPD team cooperation. Furthermore, various moderators, reflecting the supplier's dependence on the customers (customer power and customer participation) and the supplier's environmental uncertainty (market dynamism and technological turbulence), affect the strength of the underlying relationships. The results show that customer power positively affects the relationship between intrapersonal team characteristics and team cooperation. In addition, a negative moderation occurs in interpersonal characteristics. Customer participation exhibits opposing moderating effects. Regarding the supplier's environmental uncertainty, market dynamism and technological turbulence strengthen the relationships under consideration.  相似文献

This article explores the nature of the paradox inherent in coopetition; that is, the simultaneous pursuit of cooperation and competition between firms, and emanating tensions that develop at individual, organizational, and inter-organizational levels. We dissect the anatomy of the coopetition paradox to discover how it materializes by creating an external boundary (i.e., via unifying forces) and internal boundaries (i.e., via divergent forces). After explaining the coopetition paradox, we distinguish tension from paradox and submit that tension comprises both positive and negative emotions simultaneously, also known as emotional ambivalence. Finally, we recognize that emotional ambivalence in coopetition prevails at different levels, and vary in its level of intensity and persistency in relation to different contexts. We employ illustrative cases to ground our propositions empirically. This article provides understanding on concepts, expects to incite fruitful dialogue, and fuels further studies on inter-firm paradoxes.  相似文献

Research on analyst bias typically identifies affiliation with reference to a subset of the mandates that could give rise to incentives for bias in a multifunction investment bank. This paper develops a new measure of affiliation based upon the UK practice of corporate broking. An advantage of this approach is that affiliation is no longer restricted to isolated equity issuance events as it is an ongoing activity. This research shows that prior US evidence regarding the “Global Settlement” is robust to this new measure and application in the United Kingdom rather than solely the United States. The paper uses a hazard rate methodology focusing on the timeliness of revisions to address selection bias concerns.  相似文献
