Branding and relationships: Customer and supplier perspectives

This paper explores and investigates the role of branding within financial services. Specifically, the study aims to assess the importance of branding and its associated elements including brand image and brand experience in the relationships that exist between consumers and their financial brands. It aims to achieve this through research, which identifies gaps between the managerial and consumer perspectives on branding in relationships in retail financial services. It is well established that the characteristics of services are different from those of manufactured goods and that service personnel play a central role in the services experience. Moreover, the concept of relationship marketing within services proclaims the importance of one-to-one relationships between businesses and customers as well as relationships between consumers and their brands. Drawing from the fields of brand management, relationship marketing and services marketing, this research aims to investigate the perceptional differences between consumers and suppliers in relation to the importance of branding in financial service relationships. The research findings indicate that brand experience appears to be far more salient than brand image in shaping and building meaningful and lasting brand perceptions and promoting customer retention.     

Corporate social responsibility and marketing: An integrative framework

This article introduces a conceptualization of corporate social responsibility (CSR) that emphasizes the role and potential contribution of the marketing discipline. The proposed framework first depicts CSR initiatives as the actions undertaken to display conformity to both organizational and stakeholder norms. Then, the article discusses the managerial processes needed to monitor, meet, and even exceed, stakeholder norms. Finally, the analysis explains how CSR initiatives can generate increased stakeholder support.

Vying for time. Work and family

Time--there is never enough of it. There are never enough hours in the day to do everything at work and at home. Today's employees, forced to choose between work obligations and family responsibilities, often feel frazzled and guilty. Some employers recognize these conflicts and are finding ways to lighten the work/family load. They are offering a sophisticated combination of dependent-care options, flexible work hours and family-related benefits tailored to meet the needs of the employees within their specific industries. HRMagazine looks at leaders in six major industries--manufacturing, health, communications/technology, financial management, government and retail. No one can give employees that 25-hour day that everyone feels they need to juggle all their work and family obligations. But these industry leaders have provided a nurturing environment where employees can successfully balance those obligations.     

Linking Public Investment to Private Investment. The Case of Spanish Regions

Public investment constitutes one of the main instruments of regional policies. The existence of a direct link between infrastructure and regional income per capita is usually accepted. Literature also describes a positive effect of public investment on private capital accumulation. This paper seeks to provide new empirical evidence on this latter relationship for the case of Spanish regions over the period 1965–1997 using panel data methodology. The results show a positive effect of productive and social public investment (especially in education) on private investment. The spillover effects generated by the productive infrastructures located in other regions do not seem to encourage the private investment in neighbouring regions. Public consumption and interest rate exert a negative influence on private capital accumulation. These results are robust to changes in the econometric specification.     

REASONS FOR DELISTING AND CONSEQUENCES: A LITERATURE REVIEW AND RESEARCH AGENDA

This paper discusses the literature on delisting, drawing on USA and international evidence. Given the great heterogeneity in delisting operations, we first consider the standard existing typology based on the initiator of the delisting (the stock market authorities, or the firm itself). Second, while managers often cite high compliance costs (especially due to Sarbanes–Oxley Act implementation) as the official reason for the voluntary delisting of their firm, we highlight that firms face different trade-offs in their delisting decision. We also examine the reasons for involuntary delisting, especially the delisting dilemma faced by stock market authorities when the firm violates the listing requirements. Next, we review the economic consequences of delisting in terms of value creation or value destruction for shareholders. Finally, noting gaps in the literature and other contrasting results, we propose suggestions for future research.     

How many educated workers for your economy? European targets,optimal public spending,and labor market impact

This paper studies optimal taxation schemes for education in a search-matching model where the labor market is divided between a high-skill and a low-skill sector. Two public policy targets - maximizing the total employment level and optimizing the social surplus - are studied according to three different public taxation strategies. We calibrate our model using evidence from thirteen European countries, and compare our results with the target from the Europe 2020 Agenda for achievement in higher education. We show that, with current labor market characteristics, the target set by governments seems compatible with the social surplus maximization objective for some countries, while being too high for other countries. For all countries, maximizing employment would imply higher educational spending than that required for the social surplus to reach its maximum.     

Association Between Independent Auditor Fees and Firm Value： A Study of Brazilian Public Companies

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.
