On Modelling Speculative Prices: The Empirical Literature

Traditionally, financial theory and in particular asset pricing models have assumed (implicitly or explicitly) a certain probabilistic structure for speculative prices. The probabilistic structure is usually defined in terms of specific statistical models and relates to the dependence, heterogeneity and the distribution of such prices. The primary objective of this paper is to trace the development of various statistical models proposed since Bachelier (1900), in an attempt to assess how well these models capture the empirical regularities exhibited by data on speculative prices.     

Impact of airport green atmospherics on mental health value,image, and loyalty among visitors and workers

Nature‐based solutions (NBS) are becoming increasingly crucial as NBS brings diverse health‐related benefits to travelers and workers in the tourism business sector. This research explored the influence of green atmospherics as NBS on airport occupants' mental health value, image, and loyalty generation processes. A quantitative approach with a field survey method was employed. A structural equation modeling and metric invariance test were used as data analysis technique. Our empirical result revealed that green atmospherics as NBS significantly improve the occupants' mental health value and image of the airport, and these variables contribute to their loyalty enhancement for the airport. The effect of green spaces and natural surroundings on loyalty was maximized through mental health value and image. In addition, the linkages from natural surroundings to mental health value and image were stronger in the visitor group whereas the mental health value—loyalty relation was stronger in the worker group.     

NGOs and the creation of value in supply chains

Research Summary: Firms and nongovernmental organizations (NGOs) often collaborate to establish new supply chains. With a formal model, we analyze how NGOs can alleviate market failures and improve supplier economic inclusion while strategically interacting with firms. We account for the specific goals of the NGO and the need to induce collaboration between firms and their suppliers. The analysis reveals a “valley of frustration,” when NGO efforts benefit all actors but only marginally the firm. We also show that more powerful firms might prefer to internalize NGO functions, while firms with lower bargaining power and higher investment requirements are better off collaborating with NGOs. Finally, we study NGOs-firms matching patterns and find that firms with higher bargaining power match with NGOs holding stronger capabilities. Managerial Summary: This article analyzes interactions between firms and nongovernmental organizations (NGOs) aiming to improve the economic inclusion of suppliers or to promote the adoption of specific (e.g., sustainable) practices. For firm executives, this study shows the constraints and benefits associated with working with NGOs, the conditions under which integration of NGO functions is preferable as well as the types of NGOs that offer better prospects for a successful collaboration. For NGO executives, it highlights the need to provide enough economic incentives to firms and suppliers alike to ensure their collaboration and the trade-offs associated with this constraint, in particular, if NGO capabilities are limited. Overall, the study provides a comprehensive understanding of how NGO activities can influence value creation in a vertical value chain.     

In and Out of Balance: Industry Relatedness,Learning Capabilities and Post-Acquisition Innovative Performance

The existence of an inverted U-shaped effect of the relatedness between acquirer and acquired firm on the innovative performance subsequent to an acquisition is normally regarded as indicative of the existence of a trade-off between exploration and exploitation in external innovation search. We argue that acquirers endowed with heterogeneous learning capabilities can alter the shape of the trade-off to their favour. In particular, we focus on a notion of industry relatedness that captures the coherence between the domains of operation of the acquirer and the acquired firm. Using a longitudinal dataset of 1,736 domestic acquisitions in the Netherlands, we show that the heterogeneous learning capabilities of the acquirers alter the shape of the inverted-U relationship, according to first- and second-order moderating effects. Our results confirm that learning capabilities by internal R&D and by acquisition experience both improve what acquirers can achieve in innovative performance when industry relatedness is at the point of balance between exploration and exploitation. In contrast, they have opposite implications on the potential losses in innovative performance when industry relatedness is outside the point of balance: internal R&D increases the tolerance of the trade-off, smoothing out potential innovation losses, whereas acquisition experience reduces it.     

Towards a typology of business process management professionals: identifying patterns of competences through latent semantic analysis

While researchers have analysed the organisational competences that are required for successful Business Process Management (BPM) initiatives, individual BPM competences have not yet been studied in detail. In this study, latent semantic analysis is used to examine a collection of 1507 BPM-related job advertisements in order to develop a typology of BPM professionals. This empirical analysis reveals distinct ideal types and profiles of BPM professionals on several levels of abstraction. A closer look at these ideal types and profiles confirms that BPM is a boundary-spanning field that requires interdisciplinary sets of competence that range from technical competences to business and systems competences. Based on the study’s findings, it is posited that individual and organisational alignment with the identified ideal types and profiles is likely to result in high employability and organisational BPM success.     

Accidental activists: headhunters as marginal diversity actors in institutional change towards more women on boards

We present a qualitative study that examines the role of headhunters as actors in a broader institutional change process aiming to increase gender diversity on corporate boards. We draw on institutional and diversity management theories to conceptualise their change agency in the broader field of women on boards. We describe their role as ‘accidental activists’ and theorise two micro‐processes that define their change agency in this field: voluntaristic framing of intentionality and role redefinition by drawing on competing logics. This conceptualisation does not match the heroic image of the institutional entrepreneur driving institutional change, or that of the tempered radical championing diversity, but rather casts light into a marginal and previously neglected change role. We demonstrate the opportunistic and precarious nature of this role with regard to both institutional change and diversity management and discuss its possibilities and perils.     

THE GENDER GAP IN PRIVATE PENSIONS

In many western countries, older women receive considerably less private pension income than older men on average. We analyse this differential in Britain, examining differences between the sexes both in private pension coverage and in pension income conditional on receipt. Using regression‐based decompositions, we show that both gender gaps are associated mainly with differences in returns to personal characteristics rather than with differences in personal characteristics per se.     

Surges and stops in greenfield and M&A FDI flows to developing countries: analysis by mode of entry

This paper investigates the factors associated with foreign direct investment “surges” and “stops”, defined as sharp increases and decreases, respectively, of foreign direct investment inflows to the developing world and differentiated based on whether these events are led by waves in greenfield investments or mergers and acquisitions. Greenfield-led surges and stops occur more frequently than mergers-and-acquisitions-led ones and different factors are associated with the onset of the two types of events. Global liquidity is the factor significantly and positively associated with a surge, regardless of its kind, while a global economic growth slowdown and a surge in the preceding year are the main factors associated with a stop. Greenfield-led surges and stops are more likely in low-income countries and mergers-and-acquisitions-led surges are less likely in resource-rich countries than elsewhere in the developing world. Global growth accelerations and increases in financial openness, domestic economic and financial instability are associated with mergers-and-acquisitions-led surges but not with greenfield-led ones. These results are particularly relevant for developing countries where FDI flows are the major type of capital flows and suggest that developing countries’ macroeconomic vulnerability increases following periods of increased global liquidity. As countries develop they typically become more exposed to merger-and-acquisition-led surges, which are more likely than greenfield-led surges and stops to be short-lived and associated with domestic macroeconomic policies.
