Pricing Ratchet Equity-Indexed Annuities with Early Surrender Risk in a CIR++ Model

In this article we propose a lattice algorithm for pricing simple Ratchet equity-indexed annuities (EIAs) with early surrender risk and global minimum contract value when the asset value depends on the CIR++ stochastic interest rates. In addition we present an asymptotic expansion technique that permits us to obtain a first-order approximation formula for the price of simple Ratchet EIAs without early surrender risk and without a global minimum contract value. Numerical comparisons show the reliability of the proposed methods.     

Pricing American barrier options with discrete dividends by binomial trees

We are concerned with the problem of pricing plain-vanilla and barrier options with cash dividends in a piecewise lognormal model. In the plain-vanilla case, we offer a method with provides thin upper and lower bounds of the exact binomial price. In the barrier case, we provide an efficient algorithm based on suitable interpolation techniques. As by-product, we provide a new method for pricing American barrier options with continuous dividends.     

Label Style and Color Contribution to Explain Market Price Difference in Italian Red Wines Sold in the Chinese Wine Market

This study employs a hedonic price methodology to investigate the implicit price of individual labelling characteristics of Italian red wines sold in the Chinese market. Our results highlight the most important quality attributes (extrinsic and intrinsic) given in the label capable to explain price difference. In particular, reveal significant premium price for wine origin, identified in particular through the DOC/DOCG appellation given in the label, and for clean labels or labels with particular designs. On the contrary, a price discount has been revealed for Italian wines produced with local grape varieties and with a label characterised by warm colors. These results, partly in disagreement with other empirical evidence, contribute to enrich the existing literature in this field by providing useful suggestions both to the producers and other stakeholders operating in the wine industry.     

Knowledge Management Tools, Inter-Organizational Relationships, Innovation and Firm Performance

The business value of information technology is an enduring research question. This research provides new insights to better understand the mechanisms supporting this relation by analyzing the impact of knowledge management tools (KMTs) on the performances of business units involved in inter-firm collaborative innovation projects. We extend current literature by developing and empirically testing a model where: (1) the use of KMTs is affected by critical organizational variables, (2) KMTs can impact the innovation and financial performances of business units. We find that mutual trust and culture for change do not affect the extent of the use of KMTs, while collaborative experience and naturalness in using ICTs as substitutive of face-to-face contacts have a significant impact. Moreover, we show that a more intense use of KMTs has a direct positive effect on new product performance and speed to market, as well as on financial performance. Yet, only new product performance acts as an indirect conduit linking KMT use and financial performances. This article provides a discussion and perspectives of further research concerning the impact of KMTs on innovation practices in inter-firm collaborative environments.     

To Pay or Not to Pay? Dynamic Transparency and the Fight Against the Mafia’s Extortionists

This article presents the results of the longitudinal study of Addiopizzo, a successful anti-bribery organization founded in Sicily in 2004. It analyzes how this organization has used information disclosure as a strategy to fight adverse environmental conditions and the immoral activities of the Sicilian Mafia. This article extends the business ethics and corporate social responsibility literature by showing how multi-level strategic information disclosure processes can help gain organizational legitimacy in adverse social environments and successfully fight against social resistance to change, low levels of moral imagination and attacks from criminal organizations. This article provides an additional contribution to the literature by linking the three research streams on corporate transparency, the fight against corruption, and organizational legitimacy. The results of this research also contribute to the special issue of the EBEN AC 2010, “Which values for which organizations”, since it provides a unique example of an organization capable of spreading the values of social justice and honesty in a difficult social environment plagued by Mafia.     

Random and fuzzy utility models for road route choice

The objective of this work is the specification, calibration and validation of a route choice model distinguishing the phases of set perception and route choice among the alternatives belonging to the chosen set. Route generation is performed with a selective multi-criteria approach; route choice is performed using random and fuzzy utility models. As regards the fuzzy utility models, a new specification of a fuzzy model is introduced. Random and fuzzy utility models are compared and applied on a test road network and were specified and calibrated for national road freight transport on a real Italy-wide network.
