Best-performing US mutual fund families from 1993 to 2008: Evidence from a novel two-stage DEA model for efficiency decomposition

When analyzing relative performance, especially at the institutional level, the traditional data envelopment analysis (DEA) models do not recognize vastly different and important activities as separate functions and therefore cannot identify which function may be the main source of inefficiency. We propose a novel two-stage DEA model that decomposes the overall efficiency of a decision-making unit into two components and demonstrate its applicability by assessing the relative performance of 66 large mutual fund families in the US over the period 1993–2008. By decomposing the overall efficiency into operational management efficiency and portfolio management efficiency components, we reveal the best performers, the families that deteriorated in performance, and those that improved in their performance over the sample period. We also make frontier projections for poorly performing mutual fund families and highlight how the portfolio managers have managed their funds relative to the others during financial crisis periods.     

Preferential trade agreements and their role in world trade

This paper investigates the effects of preferential trade agreements (PTAs) on bilateral trade using a comprehensive data base of PTAs in force and a detailed matrix of world trade. Total trade between PTA partners is a poor proxy for preferential trade (trade in tariff lines where preferences are likely to matter): while the former was one-third of global trade in 2000–2002, the latter was between one-sixth and one-tenth. Gravity model estimates indicate that using total trade to assess the impacts of PTAs leads to a significant downward bias in the PTA coefficient: the semi-elasticity of trade with respect to PTA membership rises from 87% for total trade to 119% for preferential trade. Product exclusions and long phase-in periods significantly limit preferential trade; the marginal impact of South-South agreements on preferential trade is much higher than North-South PTAs, while the effect of North-North agreements is insignificantly different from zero.     

Variety in the video game industry: An empirical study of the Wundt curve

This study analyzes the effect of variety on consumer utility using historical behavioral information for 1,397 consumers participating in 729,049 unique rounds of play. We show that consumers generally exhibit a preference for variety as part of their gameplay utility. The relationship between variety and utility is nonlinear and follows, at least for some types of variety, an inverted u‐shape as predicted by the Wundt curve. Our results represent the first such evidence on the importance of variety in video gaming, which has significant implications for consumption through optimization of gameplay utility to satisfy the demand for variety.     

“I will survive”: Online streaming and the chart survival of music tracks

Digital streaming has had a profound effect on the commercial music sector and now accounts for 80% of industry revenues in the United States. This study investigates the consumption of music on digital streaming platforms by analyzing the factors affecting the chart survival of individual music tracks. Our data are taken from the Spotify Global Top 200 between January 2017 and January 2020, containing observations on 3,007 unique tracks by 642 artists over 1,087 days. We identify a number of unique consumption traits applicable to online streaming services, which we use to explain variations in chart longevity. We find a positive association between the amount of time a track spends in the chart and the involvement of a major label. We also find that the level of competition from other chart entries, as well as some elements related to the pattern of diffusion, associates significantly with the likelihood of chart survival. The study highlights several important managerial implications for key industry stakeholders.     

Foreign Ownership and Firm Innovation: Evidence from Korea

ABSTRACT

This study examines whether foreign equity investment promotes domestic firms’ innovation activities. Using panel data on the Korean firms during the 1999–2013 period, we find that foreign ownership has a positive effect on firms’ innovation activities. Furthermore, we also show that, as compared to non-chaebol firms, chaebol firms’ innovation activity becomes much greater with the increase of foreign ownership. Finally, we investigate industry-level spillover effects of innovation. Specifically, we find that foreign ownership promotes innovation activities via forward linkage, the effect of which is also more pronounced in chaebol firms.     

Relationship disconnect in retail banking

It has been established that increasing the role of technology in a service organisation can serve to reduce costs and improve service reliability. It is argued, however, that there remains an important role for personalised relationships in the delivery of any service proposition. Throughout this paper both of these perspectives will be discussed and an attempt is made to reconcile these apparently opposing views in the emerging age of technology-enabled remote relationships. Findings from a longitudinal research study with a large UK case bank that focused on the area of remote relationships are revisited and reinterpreted with management from the case bank in question. Through this reflective lens the bank's recent strategic decision to no longer proactively relationship manage its personal customer base is examined. In light of this deliberate relationship disconnection strategy key marketing implications are discussed.     

Can Employees Be Used to Overcome Independent Audit Limitations?

Independent financial statement auditors are appointed by shareholders to provide reasonable assurance on the reliability of financial statements published by management of reporting entities. However, in the last two decades questions have been raised concerning the credibility of external audits due to their apparent failure, especially following the spate of corporate collapses. This paper applies a critical review of literature and a multi‐theoretical governance perspective to examine the inherent limitation of independent external audits and argues that employees can contribute to reducing the limitation gap by strengthening governance through a structure that incorporates a board and employee management representation. It is argued that through this arrangement, auditors can benefit as they will be privy to additional information from employees about issues such as irregular matters that impact upon shareholders and other stakeholders, and control weaknesses across governance levels, allowing auditors to establish a broader understanding of organisational information that may otherwise be less readily available. Thus auditors can base their judgements in terms of audit risks, and develop audit plans based on more reliable information. The theoretical proposition emerging from these findings is that the traditional governance model should be refined to include employees as an additional component of governance.     

Microfoundations

This paper argues that the microfoundations programme can be understood as an implementation of an underlying methodological principle—methodological individualism—and that it therefore shares a fundamental ambiguity with that principle, viz, whether the macro must be derived from and therefore reducible to, or rather consistent with, micro-level behaviours. The pluralist conclusion of the paper is not that research guided by the principle of microfoundations is necessarily wrong, but that the exclusion of approaches not guided by that principle is indeed necessarily wrong. The argument is made via an examination of the advantages claimed for dynamic stochastic general equilibrium models, the relationship between parts and wholes in social science, and the concepts of reduction, substrate neutrality, the intentional stance and hypostatisation.     

Framing the UK’s counter-terrorism policy within the context of a wicked problem

Terrorist attacks can be seen as the ultimate wicked problem. After 9/11, terrorists moved from so-called ‘spectacular’ events to relatively low-intensity attacks against individuals and groups. The emergence of what has become known as the ‘home-grown’ terrorist has added a further dimension to the ‘wicked’ nature of the problem. This paper considers the UK’s CONTEST and PREVENT strategies as a policy response to the threats from terrorism and the impact that the policies themselves can have on the radicalization of individuals. The author highlights some of the limitations of the PREVENT strand of the overall strategy and the constraints that are imposed on government policies by failing to take a holistic perspective on the nature of the problem.
