Vers une gouvernance d'entreprise effectuale ?
2017
L’effectuation, une forme de rationalite des acteurs mise en avant par Saras Sarasvathy et Herbert Simon, trouve de plus en plus d’applications, notamment dans le domaine de l’entrepreneuriat. Cette rationalite s’applique particulierement lors de la creation d’opportunites d’investissement. L’objectif de cet article est de s’interroger sur les mecanismes favorisant les prises de decision suivant une rationalite effectuale permettant ainsi d’elaborer les fondements d’une gouvernance d’entreprise « effectuale ». Les limites des theories de la gouvernance d’entreprise actuelles sont d’abord mises en avant de facon a montrer ensuite comment integrer l’effectuation. Les specificites d’une gouver…
Governing Complex Strategic Networks: Emergence Versus Enabling Effects
2017
In today’s knowledge-based economy, the sources of competitive advantage increasingly lie in webs of relationships between a variety of firms and organizations that, over time, lead to the emergence of strategic networks. As the performances of both the network actors and the whole network are strictly linked with the coordination and governance of network actors and their activities, this study aims to shed light on the ways in which the processes of network coordination and governance take place. Strategic networks are here viewed as complex adaptive systems, and the twin nature of the processes of strategic network coordination and governance is examined. On one hand, I underscore the em…
L'efficacité des privatisations françaises : une vision dynamique à travers la théorie de la gouvernance
2004
International audience; A reading of the process of privatization through the corporate governance theory leads to propose a model taking into account, on the one hand, the time dimension of the process of privatization, on the other hand, the contextual, organizational, governance and strategic variables which influence this process. After replicating some traditional tests, we test this model on a sample of French privatized firms and on a seven years horizon. The positive effect traditionally attributed to privatizations is not confirmed. The importance of the effect is subordinated to some of the suggested variables.; Une lecture du processus de privatisation à travers la théorie de la …
Fostering Dynamic Growth in New Ventures through Venture Capital: Conceptualizing Venture Capital Capabilities
2017
There is ample evidence of the influence of venture capital on the creation and growth of new ventures, yet scant attention has been paid to the heterogeneity of venture capitalists and their capacity to contribute to the dynamic growth of new ventures. This paper aims to contribute to the existing literature by exploring the notion that venture capitalists have beneficial effects on the growth of new ventures when they rely on a set of distinctive skills and processes that we associate with venture capital capabilities. We bridge the venture capital and resource-based view research streams to identify the foundational mechanisms of venture capital capabilities. We develop a set of proposit…
Unveiling the Role of Multiple blockholders: Evidence from Closely Held Firms.
2019
Research Question/Issue. This paper disentangles how the modes of ownership distribution among multiple blockholders and their heterogeneity shape principal–principal conflicts and, in turn, affect firm performance. The paper offers empirical evidence from a panel of Italian closely held firms over the period 2009–2014. Research Findings/Insights. We explore the principal–principal conflicts among blockholders across two distinct control structures. When a single blockholder controls the firm, principal–principal conflicts are shaped by the trade‐off between the alignment effect and the monitoring effect. In this scenario, we find that the relationship between the two largest blockholders' …
L'apport du sentiment de l'investisseur dans l'explication des crises boursières : Une analyse en données de panel
2011
Un debat tres anime portant sur le lien entre les aspects comportementaux des investisseurs et les marches financiers s’est largement developpe au cours de la derniere decennie. La presente etude teste l’impact du sentiment de l’investisseur sur un panel de marches boursiers internationaux. Nous etudions l’influence du sentiment de l’investisseur sur la probabilite de survenance des crises boursieres. Nos resultats montrent que les crises boursieres sont precedees de periodes de montee de l’euphorie des investisseurs.
Struggle over joint audit: on behalf of public interest?
2012
International audience; European Commission (EC 2011) has recently suggested joint audit - broadly defined as an audit where two independent auditors are jointly liable for the audit report - as a way a way to increase audit quality after the financial crisis and to mitigate audit market concentration, by enlarging the audit offer. Big 4 audit firms have fought this proposal by arguing its unbearable cost while 2nd Tier audit firms have supported it by arguing its added quality. This conflicting position leads us to question their claim of public interest concern. As group-interest economic regulation theories predict that the absence of any effect of a new regulation (here: joint audit) is…
Relative Reachability Analysis as a Tool for Urban Mobility Planning
2019
There is a plethora of user-oriented route planning applications and systems that enable the computation of the fastest journey between two locations using different transportation modes, e.g., car, public transport, walking, bicycle. While useful for individuals, they are of limited interest to a class of users that may be interested in a more global and comparative view of transportation systems in general. In this context, we adopt the view of an urban planner. Urban planners may be interested in queries such as "if a new transit stop was to be introduced in a given location, would that bring the travel time to a given point-of-interest (POI) or area-of-interest (AOI) by bus closer to th…
Methodology and trends for an intelligent transport system in developing countries
2018
Abstract Increasingly, the technologies that are used in telecommunications contribute to improve intelligent transport systems. These technologies are systems that offer several concepts like vehicular ad hoc networks, which allow reduction of traffic accidents, traffic congestion and consequently increase road safety and the comfort of road users. Developing countries in general and those of sub-Sahara in particular do not have telecommunication infrastructures, even road infrastructures for the implementation of an intelligent transport system. Moreover, with the serious increase in vehicles in these countries, the problem of traffic regulation arise especially in the inter-urban context…
Using a hazard-independent approach to understand road-network robustness to multiple disruption scenarios
2021
Abstract A range of predictable and unpredictable events can cause road perturbations, disrupting traffic flows and more generally the functioning of society. To manage this threat, stakeholders need to understand the potential impact of a multitude of predictable and unpredictable events. The present paper adopts a hazard-independent approach to assess the robustness (ability to maintain functionality despite disturbances) of the Sioux Falls network to all possible disruptions. This approach allows understanding the impact of a wide range of disruptive events, including random, localised, and targeted link failures. The paper also investigates the predictability of the link combinations wh…
