Pourquoi un excès de confiance nuit à l’innovation
Nous présentons ici les résultats d’une étude expérimentale qui indique que lorsque deux partenaires s’engagent dans un développement conjoint, la confiance mutuelle augmente l’investissement dans le partenariat, mais il existe un niveau de confiance optimale pour maximiser la créativité : en dessous et au-dessus de ce niveau, la créativité conjointe sera moindre. Les dirigeants d’entreprise doivent donc surveiller l’évolution de la confiance au sein des équipes de développement qui est un facteur critique du succès de la coopération.

The dynamics of relational quality in co-development alliances
Co-development alliances are a specific form of cooperative arrangements which firms engage in with the intention of creating new products, services or technologies through coordinated efforts and commitment with other organisations. These cooperative agreements have been increasing in numbers over the past few decades. In this article, we discuss the role of relational quality, a construct that has been recognised as affecting the survival and ultimate success of alliances. We argue that relational quality is especially critical in co-development alliances, and propose a model for analysing it, and its drivers, based on a set of retrospective and longitudinal case studies that we conducted. We formulate several research propositions that can be derived from the model presented.

Profitability vs. Credit Score Models — A New Approach to Short Term Credit in the UK
The profitability lending model was initially discussed by Eisenbeis  who suggested that it might be possible to build a lending model that prevailed the traditional scorecard models. In this paper, we study a unique dataset from a personal loan company based in the United Kingdom, which offered overdraft- style short-term loans to individuals with low and high credit scores during the last few years. Our results conclude that credit score does not significantly impact profitability in the overdraft market. Moreover, we argue that, assuming a good understanding of low credit score individuals, a business model that grants loans to these “new” customers is as sustainable and commercially viable as lending to higher credit profile applicants.

The Orange Case
The case presents an imaginary situation in which students are asked to make decisions concerning a very simple business initiative: a hut selling oranges and orange juices on a small isolated island. It offers an accounting and company valuation exercise by focusing on financial statements preparation and estimation of earnings. Through the case, students realize fairly quickly how intrinsically complex and assumption based is assessing the value of an existing business activity. The Orange case is intended as an integrative exercise for Master in Management and MBA students, once that they have completed all the accounting, budgeting and corporate finance courses. It may also be useful within an Entrepreneurship / Venture Capital course. The main issue tackled by this exercise is that students enrolled in the mentioned programs are normally taught how to analyse and interpret financial statements, without ever being confronted with the challenge of preparing them.
