Theatre-based learning to foster corporate legacy change
No full text"Purpose: The current literature relating New Public Management (NPM) with effective organizational change is mostly focused on how the private sector’s managerial methods and tools can be better applied to the public sector by “modernizing” it, allowing for a more rational use of resources and improved economic performance. The success with regards to the implementation of major organizational change is increasingly measured by standardized quality management tools, used mainly by the private sector, such as balanced scorecards or performance-related salaries. While these managerial devices are, for the most part, understood and readily accepted by internal stakeholders in the private sector, studies have shown that they can trigger unexpected and unwanted dynamics in public companies, which often have a larger mandate, both in scope and purpose, than their private counterparts. An increasing number of scholars argue that private sector managerial tools and methods cannot be merely imposed upon employees in the public sector due to the possible generation of resistance or detriment to the intended outcomes of the organizational change desired.

A structural model for credit risk with switching processes and synchronous jumps
No full textInternational audienceThis paper studies a switching regime version of Merton's structural model for the pricing of default risk. The default event depends on the total value of the firm's asset modeled by a switching Lévy process. The novelty of this approach is to consider that firm's asset jumps synchronously with a change in the regime. After a discussion of dynamics under the risk neutral measure, two models are presented. In the first one, the default happens at bond maturity, when the firm's value falls below a predetermined barrier. In the second version, the firm can enter bankruptcy at multiple predetermined discrete times. The use of a Markov chain to model switches in hidden external factors makes it possible to capture the effects of changes in trends and volatilities exhibited by default probabilities. With synchronous jumps, the firm's asset and state processes are no longer uncorrelated. Finally, some econometric evidence that switching Lévy processes, with synchronous jumps, fit well historical time series is provided
The contribution of implicit cognition to the Theory of Reasoned Action Model: a study of food preferences
No full textInternational audienceAttitudes are at the heart of the Theory of Reasoned Action (TRA), but problems in defining and measuring attitudes have contributed to typically low ability to predict behaviour. This article investigates the impact of potential disjuncture between evaluations that an individual externally verbalises (explicit attitudes), and evaluations that are internally held and may exist outside of conscious awareness (implicit attitudes), on the predictive ability of TRA. We study consumers’ attitudes towards eating healthy food and subsequent behaviour in a context of socially consensual behaviour. An Implicit Association Test (IAT) is used to measure implicit attitudes, and these scores are contrasted with self-reported explicit attitude scores. Ninety one participants took part in the study. We found, surprisingly, that implicit attitude has no significant effect on behavioural intention. However, a disjuncture between an individual’s implicit and explicit attitudes, reflecting internal psychological conflict, affected behaviour
The Long-Run Performance Following Convertible Debt Offerings: Does The Design Matter?
No full textInternational audienceThis paper examines the impact of convertible debt design on the long-run stock price performance of the issuing firms in France. More specifically, we divide French convertible bonds (CBs) into three categories; namely, debt-like, mixed, and equity-like CBs, based on their total conversion probability, which integrates the possibility of early exercise of the call feature. In line with previous empirical studies, our results show that French CB issuers experience a substantial increase in their stock price profitability before the offering followed by significant under-performance over the three year post-issue event window. However, the breakdown of our sample into three groups of CBs depending on their design reveals, on one hand, a strong evidence of stock price run-up before the offering only for equity-like and mixed CBs. On the other hand, the post-issue performance is worse only for equity-like issuers, indicating that the post-issue performance is poorer the more the convertible debt issuer's stock is over-valued prior to the offering. This finding is consistent with the market timing hypothesis
Redesign of global supply chains with integration of transfer pricing: Mathematical modeling and managerial insights
No full textInternational audienceUnlike the supply chain (SC) design problem which deals with the configuration of a new SC, the redesign problem assumes that a SC already exists and focuses on its reconfiguration in order to take profit of the changing logistics, financial, and fiscal advantages offered by each country. First, this requires considering specific decisions and cost factors such as those associated with facility closing and capacity relocation. These aspects are often ignored by SC design models. Second, to better capitalize on the tax advantages in each country, the redesign of SC requires the consideration of taxation rates and, mainly, transfer pricing. Indeed, companies can use transfer pricing to shift profits to lower-tax countries which may impact on the SC redesign decisions (e.g., on the relocation of operations and manufacturing facilities).This paper contributes to the literature by (1) developing a large scale optimization model that is specific to the problem of SC redesign while addressing decisions, costs, and complexity factors that are often ignored by the model-based SC design literature, (2) integrating transfer pricing in the model by using two methods, one of them is the profit split method that is dictated by the OECD transfer pricing guidelines (1995, 2010), which could be considered as a novelty in large scale SC optimization models, and (3) using the model to derive a series of insights that may be helpful for companies and governments, most of these insights are difficult to obtain without the support of models like the one developed here

Asymmetric and nonlinear pass-through of crude oil prices to gasoline and natural gas prices
No full textInternational audienceIn this article,we use the recently developed nonlinear autoregressive distributedlags (NARDL) model to examine the pass-through of crude oil prices into gasoline and natural gas prices. Our approach allowsus to simultaneously test the short-and long-run nonlinearities through positive and negative partial sum decompositions of the predetermined explanatory variables. It also offers the possibility to quantify the respective responses of gasoline and natural gas prices to positive and negative oil price shocks from the asymmetric dynamic multipliers. The obtained results indicate that oil prices affect gasoline prices and natural gas prices in an asymmetric and nonlinear manner, but the price transmission mechanism is not the same. Important policy implications can be learned from the empirical findings
An exploration of business model development in the commercialization of technology innovations
No full textInternational audienceResearch on business model development has focused on the relationships between elements of value conceptualization and organization having a linear sequence in which business models are first designed and then implemented. Another stream of research points to business model development with these elements interacting in a cyclical manner. There is a need to improve our understanding of the connective mechanisms and dynamics involved in business model development, particularly from the challenging perspective of commercializing innovations. The aim of this paper was to explore business model development during the commercialization of innovations through a case-based qualitative study. This study found from four case studies that specific elements of business model development, representative of the conceptualization of value and organizing for value creation, integrate in a dynamic and cyclical process in the commercialization of technology innovations. The study provides empirical evidence that adds new insights to literature on sequential and more interactive processes of business model development. It also contributes to literature on business model development and particularly how it relates to the commercialization of innovations
Mean time imbalance effects on unreliable unpaced serial flow lines
No full textInternational audienceThis paper investigates the benefits of deliberately unbalancing operation time means for unreliable non-automated production lines. The lines were simulated with various line lengths, buffer capacities, degrees of imbalance and patterns of imbalance. Data on two performance measures, namely throughput and average buffer level were gathered, analyzed and compared to a balanced line counterpart. A number of conclusions were made with respect to the ranking of configurations, as well as to the relationships among the independent design parameters and the dependent variables. It was found that the best configurations are a balanced line arrangement and a monotone decreasing order, with the first generally resulting in lower throughput and the second leading to lower average buffer levels than those of a balanced line. Preliminary results show that unbalanced lines cope well with unreliability
