We provide a representation theorem for risk measures satisfying (1) monotonicity, (2) positive homogeneity and (3) translation invariance. As a simple corollary to our theorem, we obtain the usual representation of coherent risk measures (i.e., risk measures that are, in addition, sub-additive; see Artzner et al. in Math Finance 9:203–228, 1999).  相似文献

We show that the standard condition for MSFE encompassing is no longer valid when the forecasts to be compared are biased. We propose a simple modification of such a condition and of tests for its validity. The theoretical results are illustrated by an empirical example on inflation and deficit forecasts, key variables for the formulation of monetary and fiscal policy.  相似文献

In this paper, we evaluate the role of a set of variables as leading indicators for Euro‐area inflation and GDP growth. Our leading indicators are taken from the variables in the European Central Bank's (ECB) Euro‐area‐wide model database, plus a set of similar variables for the US. We compare the forecasting performance of each indicator ex post with that of purely autoregressive models. We also analyse three different approaches to combining the information from several indicators. First, ex post, we discuss the use as indicators of the estimated factors from a dynamic factor model for all the indicators. Secondly, within an ex ante framework, an automated model selection procedure is applied to models with a large set of indicators. No future information is used, future values of the regressors are forecast, and the choice of the indicators is based on their past forecasting records. Finally, we consider the forecasting performance of groups of indicators and factors and methods of pooling the ex ante single‐indicator or factor‐based forecasts. Some sensitivity analyses are also undertaken for different forecasting horizons and weighting schemes of forecasts to assess the robustness of the results.  相似文献

Dynamic Asymmetric Multivariate GARCH (DAMGARCH) is a new model that extends the Vector ARMA‐GARCH (VARMA‐GARCH) model of Ling and Mc Aleer (2003) by introducing multiple thresholds and time‐dependent structure in the asymmetry of the conditional variances. Analytical expressions for the news impact surface implied by the new model are also presented. DAMGARCH models the shocks affecting the conditional variances on the basis of an underlying multivariate distribution. It is possible to model explicitly asset‐specific shocks and common innovations by partitioning the multivariate density support. This article presents the model structure, describes the implementation issues, and provides the conditions for the existence of a unique stationary solution, and for consistency and asymptotic normality of the quasi‐maximum likelihood estimators. The article also presents an empirical example to highlight the usefulness of the new model.  相似文献

Although economies, business practices and living standards have converged since WWII, corporate structures continue to differ among the advanced economies of the world. Looking at the diversity of corporate structures of large-sized firms around the world (and over time) would fascinate Charles Darwin. This work develops a critical review of the literature on political determinants of corporate governance through the Darwinian theory (including some Lamarckian aspects). As Darwin, in his work On the Origin of Species, explicates the diversity of species of tortoises, finches and iguanas of the Galapagos Islands, so Darwinism may contribute in understanding the origin and the persistence of corporate diversity. In particular, this paper takes into account politics-driven variations, their inheritances, and the subsequent selection of advantageous ‘corporate’ attributes.  相似文献

The main objective of this paper is to investigate the way subsidization mechanisms affect the cost efficiency of public transit systems, taking into account the role played by the environmental characteristics of each network. A cost frontier model is estimated for a seven-year panel of 44 Italian transit companies run under two different regulatory schemes (cost-plus or fixed-price), using the approach proposed by Kumbhakar et al. (1991), Huang and Liu (1994) and Battese and Coelli (1995). The main evidence is that, given network characteristics, transit operators with high-powered incentive contracts (fixed-price subsidies) exhibit lower distortions from the minimum costs. Environmental conditions (network speed levels) also have a significant impact on inefficiency differentials and influence the efficacy of incentive regulation. Overall, these results highlight a scope for transport policy to increase X-efficiency. Furthermore, they stress the importance of incentive theory and modern regulatory economics for the production analysis of regulated utilities.  相似文献

There has been limited coverage of the corporate responsibility (CR) practices of small and medium-sized enterprises (SMEs) in the mainstream CR literature. Furthermore, there has been no systematic analysis of the responsibilities of the high value jewellery industry and jewellery SMEs in particular. This study explores the potential for harm and value creation by individual stakeholders in fine jewellery production. Using the harm chain and institutional theory to frame our investigation, we seek to understand how small businesses within the fine jewellery industry respond to the economic, social and environmental challenges associated with responsible jewellery production, and to investigate how they perceive and negotiate the tensions between responsibility and the resistance derived from the operational norms of secrecy and autonomy within the industry. Our exploratory research provides illustrative examples of how complex harm networks operate within and across the fine jewellery industry, and demonstrates the inter-relationships that exist across the different stages of the fine jewellery harm chain. Findings suggest that institutional forces are coalescing towards a more responsible agenda for the fine jewellery industry. Moreover, while CR is a tool to disrupt harmful institutional norms and practices within such an industry, it requires the co-creation of new transformative business models and multi-stakeholder involvement including firms (SMEs and MNEs), trade associations, non-governmental organisations and consumers. Solutions include national and international legislation, price adjusted certification routes for small firms, harmonisation of industry CR standards to reduce overlap in certification and regulation and gem and precious metal “track and trace” schemes.  相似文献

ABSTRACT

Recently, social media have emerged as key marketing communication channels. In this context, consumers are increasingly gathering in online communities which have been identified as social-media-based brand communities (SMBBCs). However, notwithstanding scholars' attention towards SMBBCs, the role of consumers' gender in developing brand loyalty intention (BLI) has been scarcely explored by literature. Moreover, scant attention has been given to the analysis of whether gender is related to different propensities towards brand recommendation—identified as a proactive behavior towards a positive electronic word of-mouth diffusion (E-WOM)—in the social media context. Hence, this research aims to explore the antecedents of BLI and E-WOM by focusing on consumers' gender differences. A structural equation model has been created based on 250 surveys collected among SMBBCs of an American sportswear brand. The results showed that male consumers' BLI is influenced by engagement in SMBBCs. Instead, brand trust was the main antecedent of females' BLI.  相似文献

We discuss the issue of how schools should be financed, concentrating on the role of private funding and public funding via subnational governments as accountability mechanisms in the provision of educational services. The historical evolution of school regulation in Italy and Spain has created differences in the percentage of pupils who attend private schools, the percentage of private school funding coming from public and private sources and the percentage of public school funding that comes from central or local government sources. We take advantage of these institutional diversities rooted in history to estimate the disciplining role of these different sources of funding in the context of an educational production function using Programme for International Student Assessment (PISA) data. Our results provide support to both accountability mechanisms and point to the presence of an important interplay between them.  相似文献
