The goal of this paper is to analyze the impact of annual earnings announcements on the market through the order flow data in addition to the usual transaction data. In this respect, examining order flow data can potentially reveal valuable information that is not available from transaction data. In fact, the data allow us to test hypotheses about asymmetric information and investor behavior and to test if the behavior varies with investor sophistication. In addition, the paper tries to identify the determinants of the impact on a firm's value using assumptions about investor behavior. 相似文献

We analyze the statistical properties of three price discovery measures: The variance ratio, the weighted price contribution (WPC), and the R2 of unbiasedness regressions. We find that, if the price process is a driftless martingale, only the WPC is an unbiased estimator for the return variance explained during a time interval. For autocorrelated processes with a drift, only the R2 of the unbiasedness regression is consistent, but it is biased for small samples. 相似文献

AbstractThis article analyses reforms to contracting and accountability for indigenous primary health care organizations in Canada, New Zealand, and Australia. The reforms are presented as comparative case studies, the common reform features identified and their implications analysed.The reforms share important characteristics. Each proceeds from implicit recognition that indigenous organizations are ‘co-principals’ rather than simply agents in their relationship with government funders and regulators. There is a common tendency towards more relational forms of contracting; and tentative attempts to reconceptualize accountability. These ‘frontier’ cases have broad implications for social service contracting. 相似文献

This paper shows how to solve global games applied to macroeconomics and finance. We ascertain the roles of public and private information for the determination of a unique equilibrium, and discuss the informative role of market prices. We examine the impact of public information on social welfare, comparing models with and without complementarities at the aggregate level. 相似文献

Justifying ridge regression from a geometrical perspective is one of the main contributions of this paper. To the best of our knowledge, this question has not been treated previously. This paper shows that ridge regression is a particular case of raising procedures that provide greater flexibility by transforming the matrix X associated with the model. Thus, raising procedures, based on a geometrical idea of the vectorial space associated with the columns of matrix X , lead naturally to ridge regression and justify the presence of the well-known constant k on the main diagonal of matrix X ′ X . This paper also analyses and compares different alternatives to raising with respect to collinearity mitigation. The results are illustrated with an empirical application. 相似文献

Due to the dispersion of headquarters’ activities across organizational and geographical boundaries, intermediate units (IUs) are emerging as a key actor of international business. IUs are intermediate structural layers between headquarters (HQ) and local subsidiaries with specific HQ responsibilities. Our study relies on original data of 67 IUs and, taking on a Resource Dependence approach, explores empirically the two HQ roles attributed to IUs: coordinative versus entrepreneurial. According to our results, the main differences between both roles relate to external network embeddedness, internal network position and autonomy. We argue that these differences arise from the dominant sources of power in each role. These findings have signi?cant relevance for theory development and managerial practice as we provide a starting point for understanding the dispersion of complex HQ systems as well as how those systems are discharged and add value. 相似文献

Exploring the customer's intention to switch firms: The role of customer‐related antecedents 下载免费PDF全文

This study examined the customer‐related antecedents of the customer's intention to switch firms. Customer citizenship behavior was a key element in this study. Scholars have extensively studied the antecedents of customer citizenship behavior. However, the way that customer citizenship behavior relates to other attitudinal variables and the intention to switch has scarcely been analyzed. The proposed hypotheses were verified using partial least squares variance‐based structural equation modeling applied to 947 users of beauty care service firms in five countries. The results suggest that customer citizenship behavior is an antecedent of satisfaction, trust, and attitudinal loyalty. Two of these variables influence customers’ intentions to abandon relationships with the service provider. The implications of these findings enhance managers’ and scholars’ understanding of the determinants of customers’ intentions to switch firms. 相似文献

The literature on territorial innovation modes has identified the development of a diverse set of innovation systems at multiple levels of analysis. However, there are certain gaps that do not allow their adaptation to the particularities of certain territories. Despite the multiple concepts related to innovation systems approach, the state of the art does not yet provide a useful analytical approach for a deep and comprehensive characterization of territories with a high sectoral and technological specialization. This paper introduces an analytical framework based on a regional open and sectoral innovation system, which is qualitatively tested in the Durango County (Spain). The aim of this paper is to introduce a subtype of innovation system that meets the requirements and needs of a located micro-territory with a high level of sectoral specialization. 相似文献

Alterations in the institutional environment, as a result of the markets integration process and the consequent alterations in stakeholders’ conduct are one of the important vectors of changes in companies’ behavior. In that context, in addition to their yields those companies happen to worry about their attitudes in relation to social and environmental factors. Thus, the corporate social responsibility (CSR) is seen as one more strategy to maintain or increase their income and to harness the enterprise development. The main purpose of this study is the verification of the existing relation between Social Responsibility and the economic and financial performance of two companies in the business of Petroleum, Gas and Bio-combustibles. The investigation was based on a comparison of social-environmental practices developed by Petrobras S/A (Brazil) and Repsol S/A (Spain). For the purpose of verification of the relation between social-environmental performance and the economic-financial one, a linear regression analysis was carried out. 相似文献
