THE GINI CONCENTRATION INDEX: A REVIEW OF THE INFERENCE LITERATURE

More than a century ago, Corrado Gini proposed his well-known concentration index for measuring the degree of inequality in the distribution of income and wealth. His index is still extremely relevant and widely used in several fields of research and application. In this paper, we focus on the inferential properties of the Gini index, and discuss the main directions of analysis proposed in the literature. The aim of the paper is to provide a comprehensive review of the main developments on the inferential aspects of the Gini concentration ratio. We feel that this work can provide a valuable contribution to those scholars who are approaching the large amount of literature on the inferential properties of the Gini index.     

Brand Management as an Internationalization Strategy for SME: A Multiple Case Study

ABSTRACT

This research examines the role of branding in the Portuguese SME internationalization process and how the internationalization and brand strategies are articulated in the search for a better business performance within a competitive framework and increasing competitiveness environment. The article aims specifically at: (a) the strategy of creation and brand management; (b) the relevance given to the brand; (c) the importance of brand creation and management in the internationalization strategy. We chose a qualitative methodology, based on four cases studies. Our results suggest that branding strategies of SME cannot be compared with the strategies of multinationals. Budgetary constraints and human resources lead companies to invest in low-cost strategies. The importance of the brand lies in the distinction that allows competition with similar products within the sectors. Management of the brand does not come up as an essential strategy for the internationalization of a Portuguese SME.     

Enablers for end‐user entrepreneurship: An investigation on Italian food bloggers

This article examines unconventional entrepreneurship (accidental or end‐user entrepreneurs) to determine whether the decision‐making phase of the entrepreneurial process is collective. The analysis identified a virtuous circle that links knowledge, innovation, judgment, and decision making to collective interactions built on passion, experience, and sharing. To study food bloggers as unconventional user entrepreneurs, data were collected and analyzed using netnographic analysis. A supplementary online survey of food bloggers and their followers was also performed. Three groups of food bloggers are identified: amusing, functional, and fervent. Only fervent food bloggers, thanks to the virtuous circle built on passion, experience, and sharing as enablers, can be considered accidental or end‐user entrepreneurs.     

Model misspecification effects for biased samples

The model misspecification effects on the maximum likelihood estimator are studied when a biased sample is treated as a random one as well as when a random sample is treated as a biased one. The relation between the existence of a consistent estimator under model misspecification and the completeness of the distribution is also considered. The cases of the weight invariant distribution and the scale parameter distribution are examined and finally an example is presented to illustrate the results.     

How to implement innovation policies through projects successfully

This paper investigates the types of policy instruments responsible for the success of policy implementation through projects. Based on evidence from 12 comparative multiple case-studies, the paper provides an analytical insight from real practice on how and why different types of instruments lead to either successful or unsuccessful projects. In particular, the key finding is that in order for projects to implement policy successfully, policy instruments have to be designed based on specific systems thinking constructs related to flexibility. The findings provide the crucial but missing holistic conceptual direction for the development of implementation theory, which needs to overcome conceptual fragmentation and polarization. The findings also provide the insight as to how instruments really function which is essential to policy makers and project managers involved in public innovation programs.     

Issues in the analysis of co-authorship networks

Scientific collaboration is a complex phenomenon that improves the sharing of competences and the production of new scientific knowledge. Social Network Analysis is often used to describe the scientific collaboration patterns defined by co-authorship relationships. Different phases of the analysis of collaboration are related to: data collection, network boundary setting, relational data matrix definition, data analysis and interpretation of results. The aim of this paper is to point out some issues that arise in these different phases, highlighting: (i) the use of local archives versus international bibliographic databases; (ii) the use of different approaches for setting boundaries in a whole-network; (iii) the definition of a co-authorship data matrix (binary and weighted ties) and (iv) the analysis and the interpretation of network measures for co-authorship data. We discuss the different choices that can be made in these phases within an illustrative example on real data which is referred to scientific collaboration among researchers affiliated to an academic institution. In particular, we compare global and actor-level network measures computed from binary and weighted co-authorship networks in different disciplines.     

Sell‐Side Analyst Bias When Investment Banks Have Privileged Access to the Board

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.     

Determinants and Valuation Implications of Compulsory Stock Option Disclosures in a Weak Regulatory Setting—The Case of France

Using a sample of listed French firms in 2005, the year of mandatory IFRS adoption in the European Union (EU), we investigate the determinants of disclosure compliance of stock option expenses under IFRS 2, Share‐based Payment. Stock options are a popular means of executive compensation in France relative to other EU countries. Prior to 2005, French accounting standards and corporate governance regulations did not require recognition of option expense amounts and required minimal supplementary disclosures. There was also a perception that enforcement was imperfect, in particular with respect to IFRS 2. Given this setting, we explore what factors influence the willingness of firms to follow compulsory IFRS requirements in a weak regulatory setting. We find that overall compliance with IFRS 2 disclosure requirements increases with U.S. and U.K. institutional ownership, U.S. cross‐listing, provision of English language statements, and decreases with CEO and family ownership of the firm. We also investigate how stock market prices are affected by the recognition and disclosure of stock option expenses according to IFRS 2 in this regulatory setting and find that investors value option expenses positively, particularly when accompanied by high‐disclosure compliance. Our findings have implications for other jurisdictions in the process of adopting or converging to IFRS.     

Destination competitiveness: what we know,what we know but shouldn't and what we don't know but should

Two decades after the seminal work of Crouch and Ritchie [(1999). Tourism, competitiveness, and societal prosperity. Journal of Business Research, 44(3), 137–152], which triggered an avalanche of research on the topic, there is an extensive and still-growing body of literature on destination competiveness. Research on competitiveness, in the context of tourism destinations and even in its parent field of economics, has been characterized by controversy and strong criticism. Given the complexity of the phenomenon, the multiplicity of perspectives taken on it and the current stage of knowledge, there is a clear need for a reflective audit that enables a careful consideration on the knowledge acquired with past research as well as a well-thought-out identification of the needs for future research. Only such meticulous process will ensure the progress of this field of enquiry. The wide-spread acknowledgement of the importance of competitiveness for a destination's long-term success in addition to the constant comments that it is still a topic not well understood, suggests that research on it still has a long future ahead. This article embraces this challenging task by documenting, examining and critically assessing the existing literature on three dimensions: definitions, theoretical models and measurement. In addition, existing gaps are identified and research propositions are presented to guide future research.
