We introduce a model of product development in a firm. Our model describes the process as a multi-stage contest (i.e., race) with an endogenous length (with one stage or two stages) between two workers. We model the payments to workers from the new product using the normatively appealing Nash...

Le contrôle de gestion d’une innovation est une problématique délicate, et pour certains insoluble, en particulier lorsque le développement de nouveaux produits ou services s’appuie sur des technologies dont le modèle économique est peu connu. Toutefois, l’article présente un cadre...

L’atteinte d’un avantage compétitif dans les services bancaires passe par l’amélioration de la qualité de la relation. Or, la majorité des modèles relationnels pêchent par leur caractère statique qui ne prédit pas l’impact potentiel de l’évolution d’un paramètre dans la...

Remote work arrangements and increased virtual communication are commonplace. Particularly in organizations, virtual communication has become an essential tool for collaboration and exchanging information. Virtual communication channels, such as text or video messages, provide different levels...

This paper conducts a broad-based comparison of iterated and direct multi-step forecasting approaches applied to both univariate and multivariate models. Theoretical results and Monte Carlo simulations suggest that iterated forecasts dominate direct forecasts when estimation error is a...

In this paper we specify a multi-factor long-memory process that enables us to estimate the fractional differencing parameters at each frequency separately, and adopt this framework to model quarterly prices in three European countries (France, Italy and the UK). The empirical results suggest...

This paper investigates the limit properties of mean-variance (mv) and arbitrage pricing (ap) trading strategies using a general dynamic factor model, as the number of assets diverge to infinity. It extends the results obtained in the literature for the exact pricing case to two other cases of...

This paper extends the analysis of infinite dimensional vector autoregressive models (IVAR) proposed in Chudik and Pesaran (2010) to the case where one of the variables or the cross section units in the IVAR model is dominant or pervasive. This extension is not straightforward and involves...
