Speculation and volatility—A time-varying approach applied on Chinese commodity futures markets

Experts have long discussed and empirically investigated whether speculative activity increases volatility on commodity futures markets. Little empirical research, however, analyzes the role of speculators on commodity futures markets in China. Using time-varying vector autoregression models with stochastic volatility, this paper investigates for four heavily traded metal and agricultural contracts, how the relationship between returns volatility and speculation evolves over time. Our findings indicate that speculative activity has little to no impact on volatility. On the contrary, for all commodities examined, returns volatility seems to amplify speculation.     

The Opportunity Cost of Negative Screening in Socially Responsible Investing

This paper investigates the impact of negative screening on the investment universe as well as on financial performance. We come up with a novel identification process and as such depart from mainstream socially responsible investing literature by concentrating on individual firms’ conduct and by studying a much wider range of issues. Firstly, we study the size and financial performance of fourteen potentially controversial issues: abortion, adult entertainment, alcohol, animal testing, contraceptives, controversial weapons, fur, gambling, genetic engineering, meat, nuclear power, pork, (embryonic) stem cells, and tobacco. We investigate an international sample of more than 1,600 stocks for more than twenty years. We then analyze the impact of applying negative screens to a market portfolio. Our findings suggest that the choice for negative screening strategies does matter for the size of the investment universe as well as for risk-adjusted return performance. Investing in controversial stocks in many cases results in additional risk-adjusted returns, whereas excluding them may reduce financial performance. These findings suggest that there are opportunity costs to negative screening.

Network-centric business models for health,social care and wellbeing solutions in the internet of things

In this multiple case study we analyze solutions based on connected devices in the context of health, social care and wellbeing. Based on the consideration that a solution is a combination of services and products, we build on the notion that business models can be studied at a firm-level and also at a network-level. The network-level analysis is used to motivate the reasons why solutions emerging at the intersection of the healthcare and the ICT industries benefit from collaboration among different actors. We conclude that the firm- and the network-level development of business models provide alignment in the business network and are useful to establish the relation that technological component have with overall solutions. Our findings suggest that some component bring novelty in the final offer without affecting the ongoing operation, while other component aim at improving the internal working processes, with minimal effects on the final offer to end users. We discuss the benefits of a network-level perspective for each case.     

The digital future of internal staffing: A vision for transformational electronic human resource management

Through an international Delphi study, this article explores the new electronic human resource management regimes that are expected to transform internal staffing. Our focus is on three types of information systems: human resource management systems, job portals, and talent marketplaces. We explore the future potential of these new systems and identify the key challenges for their implementation in governments, such as inadequate regulations and funding priorities, a lack of leadership and strategic vision, together with rigid work policies and practices and a change-resistant culture. Tied to this vision, we identify several areas of future inquiry that bridge the divide between theory and practice.     

International spillovers of (un)conventional monetary policy: The effect of the ECB and the US Fed on non-euro EU countries

We estimate a global vector autoregression model to examine the effects of euro area and US monetary policy stances, together with the effect of euro area consumer prices, on economic activity and prices in non-euro EU countries using monthly data from 2001-2016. Along with some standard macroeconomic variables, our model contains measures of the shadow monetary policy rate to address the zero lower bound and the implementation of unconventional monetary policy by the European Central Bank and the US Federal Reserve. We find that these monetary shocks have the expected qualitative effects but their magnitude differs across countries, with southeastern EU economies being less affected than their peers in Central Europe. Euro area monetary shocks have a greater effect than those that emanate from the US. We also find certain evidence that the effects of unconventional monetary policy measures are weaker than those of conventional measures. The spillovers of euro area price shocks to non-euro EU countries are limited, suggesting that the law of one price materializes slowly.

Using Transaction Cost Economics to explain outsourcing of accounting

This study explores whether SMEs involved in the outsourcing of accounting tasks differ, in terms of transactional and personal (CEO) characteristics, from others that perform the same tasks within the company. We rely on the transaction cost economics (TCE) model, while controlling for age, educational background, and trust of the SME executive in the external accountant. A survey was developed to investigate the outsourcing by Belgian SMEs both of routine (entry of invoices, interim reporting) and non-routine (period-end accounting, preparation of financial statements) accounting tasks. For the routine accounting tasks, frequency was significantly associated with outsourcing. Meanwhile, for non-routine accounting tasks, asset specificity and frequency were significantly associated. High-frequency tasks were associated with lower levels of outsourcing. Similarly, higher asset specificity was associated with lower levels of outsourcing. Furthermore, the educational background of the CEO, as well as the CEO’s level of trust in the external accountant, was significantly associated with outsourcing, confirming the upper echelon theory. Having a more educated CEO was associated with lower levels of outsourcing, both for routine and non-routine accounting tasks.     

The Importance of Relationship Quality: Maximizing the Impact of Expatriate Contact with a Local Host

Contact between expatriates and a local host‐a specific type of peer mentoring‐has been shown to result in benefits to adjustment, social support, and intercultural competence. This longitudinal study examines the role of the quality of this contact. Expatriates in the Netherlands were randomly divided into an experimental group (N = 33) in which 21 participants had developed high‐quality contact with their host, and a control group (N = 32) that had no host. The results suggest the higher the quality of the contact, the more benefit the expatriate experienced. Moreover, expatriates with low‐quality contact did not experience a detrimental effect. Theoretical and practical implications for mentoring in general, and peer mentoring of expatriates specifically, are discussed. © 2015 Wiley Periodicals, Inc.
