According to a recent conjecture in the literature, earnings have become a poorer proxy for cash flow from operations over time. We find that since 1988, when cash flow statements started to be consistently reported in Compustat, the cash effectiveness of earnings has actually increased for a large sample of US manufacturing firms. This occurs despite the introduction of fair value accounting and increasing accounting accruals during the last three decades. Also contrary to the conjecture, using more comprehensive measures of cash flow does not restore the investment-cash flow sensitivity, which continues to be around 0.05 in more recent periods.  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

Three metrics are designed to assess Colombian financial institutions' size, connectedness and non-substitutability as the main drivers of systemic importance: (i) centrality as net borrower in the money market network; (ii) centrality as payments originator in the large-value payment system network; and (iii) asset value of core financial services. An aggregated systemic importance index is calculated based on expert knowledge by using a fuzzy logic inference system. We use principal component analysis to calculate a benchmark index for comparison purposes. Overall similarities between both indexes put forward that expert knowledge aggregation is consistent with that based on a purely quantitative standard approach. Specific non-negligible differences concur with the nonlinear features of an approach whose intention is to replicate human reasoning. Both indexes are complementary and provide a comprehensive relative assessment of each financial institution's systemic importance in the Colombian case, in which the choice of metrics pursues the macroprudential perspective of financial stability.

Cities are key drivers of global climate change, with the majority of greenhouse gas (GHG) emissions being tied to urban life. Local actions to mitigate and adapt to climate change are essential for stabilization of the global climate and can also help to address other urban ecological problems such as pollution, decreasing biodiversity, etc. Companies are important urban actors in the development of low‐carbon cities because they provide a multitude of goods and services to city populations and directly influence urban carbon dioxide (CO2) emissions. This is a new area of research. While studies on corporate sustainability are numerous, there is little, if any, existing research that examines the role of companies in climate change adaptation and mitigation within specific urban areas. Urban ecologists also have not examined how corporate activity affects urban systems. Taking a multi‐disciplinary systems approach, we present a conceptual model of the role of companies in managing urban interactions with the climate system. We also present empirical findings illustrating how one company ‘partners’ with the city of Rotterdam to test electric vehicles as a pilot project for urban climate adaptation and mitigation.

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

This article assesses the impact of armed conflict on the drinking water service of Basrah from 1978 to 2013 through an ‘urban warfare ecology’ lens in order to draw out the implications for relief programming and relevance to urban studies. It interprets an extensive range of unpublished literature through a frame that incorporates the accumulation of direct and indirect impacts upon the hardware, consumables and people upon which urban services rely. The analysis attributes a step‐wise decline in service quality to the lack of water treatment chemicals, lack of spare parts, and, primarily, an extended ‘brain‐drain’ of qualified water service staff. The service is found to have been vulnerable to dependence upon foreign parts and people, ‘vicious cycles’ of impact, and the politics of aid and of reconstruction. It follows that practitioners and donors eschew ideas of relief–rehabilitation–development (RRD) for an appreciation of the needs particular to complex urban warfare biospheres, where armed conflict and sanctions permeate all aspects of service provision through altered biological and social processes. The urban warfare ecology lens is found to be a useful complement to ‘infrastructural warfare’ research, suggesting the study of protracted armed conflict upon all aspects of urban life be both deepened technically and broadened to other cases.  相似文献

We discuss the theoretical rationale for central bank communication about future policy rates, either as part of inflation targeting or in the form of forward guidance. We also summarize both actual central bank communication about future policy rates and empirical evidence on the effectiveness of these types of communication. We argue that there is a disconnect between the theory and practice of forward guidance, as theory assumes commitment on the part of the central bank, while in practice central banks generally do not commit. Future theoretical research on forward guidance should therefore take the absence of commitment by central banks into account.  相似文献

This article investigates the relationship between fees for audit and non-audit services with Tobin's Q. Using a sample of Brazilian public companies in the period from 2009 to 2011, we estimate the association between Tobin's Q and the auditors' remuneration scaled by total assets. Additionally, to strengthen the conclusions, we present a second model with the remuneration of the auditors in absolute terms. The results suggest a significant relationship between Tobin's Q and audit and non-audit fees, positive and negative, respectively. Specifically, increases in audit fees and non-audit fees respectively increase and decrease the Tobin's Q of the audited company. The results of this study have important implications for those interested in good corporate governance practices. Managers and board members concerned with value carefully evaluate the remuneration and nature of services creation, when engaging independent auditors, should provided.  相似文献
