Tacit Collusion and Non–uniform Prices

This article examines the possibility of building a tacit agreement between price–setters that yields non–uniform pricing. It is shown that firms with market power may restrict competition not only by alternating between periods of high prices and low prices (Green and Porter (1984), Rotemberg and Saloner (1986)), but also by always charging different prices and taking turns in being the monopolist. In contrast with the existing literature, price variability is not due to imperfect monitoring, stochastic demand or short–run pricing rigidity but it is a pure supply side effect. The author provides the necessary conditions to have collusion with non–uniform pricing, and shows that the latter dominates a fixed price solution. In terms of competition policy this result confirms that no price parallelism is not, per se , a signal of no collusion.

On VIX futures in the rough Bergomi model

The rough Bergomi model introduced by Bayer et al. [Quant. Finance, 2015, 1–18] has been outperforming conventional Markovian stochastic volatility models by reproducing implied volatility smiles in a very realistic manner, in particular for short maturities. We investigate here the dynamics of the VIX and the forward variance curve generated by this model, and develop efficient pricing algorithms for VIX futures and options. We further analyse the validity of the rough Bergomi model to jointly describe the VIX and the SPX, and present a joint calibration algorithm based on the hybrid scheme by Bennedsen et al. [Finance Stoch., forthcoming].     

The firm,the platform and the customer: A “double mangle” interpretation of social media for innovation

The aim of this article was to explore the relationship between human actors and technology in the context of a social media platform, developed by a leading Italian firm in the food industry, and created to keep in contact with its customers, while gathering innovative ideas from them.In order to address these issues, we adopt a theoretical approach that is deeply rooted in Pickering's “mangle” theory, and Jones' subsequent metaphor of “double dance of agency” i.e. human and material agencies. A longitudinal case study has been developed with two rounds of interviews with marketing and R&D managers. A total of 8 recorded interviews, for 22 h overall.We examined conditions in the ongoing functioning of the platform, and considered how the website's dynamic materiality configures and reconfigures the practices and possibilities of different modes of engagement by multiple users (i.e. firm employees and customers) and vice versa. Specifically, dealing with the case of a social media platform developed by a firm to gain clearly defined organizational ends, the entanglement is considered to be double. One entanglement is between the human agency of customers and the material agency of the social media platform. The other is between the human agency of the firm and the material agency of the social media platform, including all actions that human agents (i.e. firm employees) undertake in seeking to channel material agency and shape actions of other human agents, i.e. customers.     

Negotiating Transfer Prices

We consider a team-investment setting in which transfer prices between two divisions are negotiable. Investments are made independently and simultaneously after the bargaining stage, i.e. with a given transfer price ‘on the table’. Both divisions’ investments jointly affect the sales price of the final product and total revenue. We analyze two transfer-pricing schemes and their corresponding bargaining problems. Both bargaining settings exhibit non-transferable utility because the transfer price not only allocates corporate profit but also affects corporate profit through the incentives it creates for the divisions’ investment and quantity decisions. In particular, we discuss how concepts from bargaining theory can be use used to determine a ‘fair’ agreement concerning the transfer price.     

Search practices for discontinuous innovation: scale development and construct validation

Managing innovation and particularly searching for new ideas in a steady state environment is really different than in discontinuous conditions where traditional practices and routines may prove ineffective. This paper reviews and empirically explores the field of search strategies and practices for discontinuous innovation and, for the first time, tests the validity of a ‘discontinuous innovation (DI) search capacity’ construct. Based on a comprehensive literature review on the innovation search stage and on the evidence of more than 80 case studies reported by the Discontinuous Innovation Laboratory, a questionnaire was developed and submitted to a 500 high-tech firm sample. Four DI search dimensions were identified, each consisting of a bundle of interrelated yet distinct practices. We empirically tested the DI search capacity and measured it as a second-order construct by using the structural equation modelling.     

Pricing and Hedging Discount Bond Options in the Presence of Model Risk

This paper focuses on pricing and hedging options on a zero-coupon bond in a Heath–Jarrow–Morton (1992) framework when the value and/or functional form of forward interest rates volatility is unknown, but is assumed to lie between two fixed values. Due to the link existing between the drift and the diffusion coefficients of the forward rates in the Heath, Jarrow and Morton framework, this is equivalent to hedging and pricing the option when the underlying interest rate model is unknown. We show that a continuous rangeof option prices consistent with no arbitrage exist. This range is bounded by the smallest upper-hedging strategy and the largest lower-hedging strategy prices, which are characterized as the solutions of two non-linear partial differential equations. We also discuss several pricing and hedging illustrations.     

Analysing affects and emotions in tourist e-mail interviews: a case in post-disaster Tohoku,Japan

ABSTRACT

This paper contributes methodological discussions on collecting and analysing international tourists’ affects and emotions. The method of data collection used is electronic mail interviews, in some instances corroborated by participant observation in the field, whereas the methods of data analysis employed are affective mapping and emotionality of texts. Such methods of analysis capture the on-flow and contingency of the tourist’s experience in post-disaster places. E-mail interviews are becoming an increasingly widespread method of data collection. In post-disaster contexts, the potential of email interviews allows researchers to conduct fieldwork even when they cannot obtain face-to-face interviews, or in cases in which participants feel more at ease answering from their home and can take their time to respond. Twelve semi-structured e-mail interviews have been conducted in 2016 with international tourists who visited the Tohoku region, Japan, hit in 2011 by a triple disaster: an earthquake, a tsunami, and a nuclear meltdown at the Fukushima nuclear power plant. To explore and better understand participants’ affective and emotional experiences, we exemplify affective mapping and emotionality of texts drawing on tools like linguistic features of e-mails, imagework, short stories and anecdotes.     

On designers’ use of biomimicry tools during the new product development process: an empirical investigation

As technological problems and societal challenges become increasingly complex, designers are urged to recombine knowledge from different sources in order to innovate. In this article we question how nature may be the key source of inspiration and whether it can impact the new product development (NPD) process. We shed new light on whether designers and researchers are: first, familiar with biomimicry tools; second, aware of their characteristics; third, in favour of using biomimicry tools in the NPD process; and fourth, able to assess the impact of biomimicry tools on the NPD performance. By analysing survey data, counterintuitive results emerged concerning both the awareness of the biomimetic tools and their impact on the NPD innovation outcomes.     

Customer co-creation projects and social media: The case of Barilla of Italy

This article investigates a social media-enabled, customer co-creation project that employs front-end innovation (FEI) at a well-known, large-scale food manufacturer. It sheds light on the role of social media technology in transforming the characteristics of FEI in terms of boundaries and knowledge distance. What type of exploratory or exploitative innovation ideas does a project of this sort enable? How did the project evolve? What lessons can be learned from this project? A longitudinal case study of Barilla was carried out through two rounds of interviews with marketing, business development and innovation, and digital communication managers. The evidence gathered highlights the emergent evolution of this customer co-creation project from an initial stage of idea exploitation to a more complex and fruitful stage in which both exploitation and exploration were simultaneously accomplished.
