| Abstract: | We study how the widespread diffusion of ICT affects wages, working conditions, and job satisfaction. We frame our empirical investigation with a model in which ICT can improve both wages and working conditions by increasing firms' output. Using French matched employer-employee data and an instrumental variable approach that is motivated by the model, we find that ICT diffusion in 2013-2019 has been beneficial to workers, who experienced both higher wages and better working conditions, particularly through greater flexibility, physical comfort, and safety. In contrast, ICT use has also increased psychological stress and work intensity. These effects vary across workers, firms, occupations and sectors, depending on their characteristics. Despite overall improvements in wages and working conditions, we estimate only modest positive effects of ICT use on job satisfaction. We discuss potential explanations for this finding. |

| Abstract: | Digital technologies have rapidly reshaped agricultural systems worldwide, and Egypt is no exception. Over the past decade, the proliferation of smartphones, mobile internet, and low-cost digital tools has opened new channels through which farmers, traders, processors, and aggregators access information and services. Smartphone applications, websites, call centers, and SMS-based platforms now offer advice on crop management, weather and climate alerts, input and output price information, traceability tools, and digital marketplaces. For smallholder farmers—who make up the backbone of Egypt`s agricultural sector—these tools have the potential to reduce information frictions, improve decision-making, and increase productivity and profitability. For larger firms engaged in aggregation, processing, or export, digital platforms can streamline supply chains, enhance coordination, and improve quality assurance. |

| Abstract: | Low Earth orbit (LEO) satellite systems are becoming an increasingly important component of global communications infrastructure, providing broadband access, enterprise connectivity, and direct-to-device services in competition with terrestrial networks. At the same time, orbital space is a congestible shared resource: satellite deployments increase conjunction risk and debris, imposing external costs on other operators. This paper analyses how these features interact by modelling LEO satellite broadband as a capacity-constrained oligopoly operating under an orbital congestion externality. We develop a two-stage model in which satellite operators first choose constellation size and research and development (R&D) investment, and subsequently compete in quantities subject to binding capacity constraints. Orbital congestion damages depend on aggregate satellite deployment, while operators are privately exposed to only a fraction of the resulting congestion risk. Three results emerge. First, oligopolistic competition and incomplete congestion internalisation generate distinct distortions: output and innovation are inefficiently low due to market power, while satellite deployment is excessive when firms do not face the full marginal social cost of congestion. Second, R&D interacts non-trivially with congestion risk through its effect on throughput per satellite, creating substitution between “more satellites” and “smarter satellites.” Third, regulatory instruments such as Pigouvian satellite charges or tradable conjunction-risk permits can correct deployment incentives but do not eliminate distortions arising from imperfect competition. These results highlight that congestion pricing and competition policy operate as complementary instruments in the governance of emerging satellite broadband markets, with implications for spectrum policy, launch regulation, and the management of shared orbital resources. |

| Abstract: | We study optimization problems in which a linear functional is maximized over probability measures that are dominated by a given measure according to an integral stochastic order in an arbitrary dimension. We show that the following four properties are equivalent for any such order: (i) the test function cone is closed under pointwise minimum, (ii) the value function is affine, (iii) the solution correspondence has a convex graph with decomposable extreme points, and (iv) every ordered pair of measures admits an order-preserving coupling. As corollaries, we derive the extreme and exposed point properties involving integral stochastic orders such as multidimensional mean-preserving spreads and stochastic dominance. Applying these results, we generalize Blackwell's theorem by completely characterizing the comparisons of experiments that admit two equivalent descriptions-through instrumental values and through information technologies. We also show that these results immediately yield new insights into information design, mechanism design, and decision theory. |

| Abstract: | The emergence of information technologies and the digitalization of information systems have a significant impact on the transformation of modern organizations as well as on the practices of management controllers, particularly through the integration of Enterprise Resource Planning (ERP) systems and Business Intelligence (BI) tools. These technological solutions enable the automation of tasks, the centralization of data, and the facilitation of decision making processes. Today, organizations increasingly rely on tools that optimize management, analysis, and sharing of information that is essential to their activities. In this context, the role of the management controller is evolving from a primarily operational function focused on the production of financial data and the assurance of information reliability within the organization toward a more analytical and strategic role. This function has undergone substantial changes with the integration of ERP and BI systems. While numerous studies have examined this issue in an international context, relatively few have addressed it within the Moroccan context. This article aims to contribute to the literature on the evolution of the management controller's role in Moroccan companies through a qualitative study conducted within two Moroccan firms, X and Y. The study is based on semi-structured interviews with four management controllers, complemented by interviews with two financial managers. The two companies studied have well-structured management control functions and make use of technological tools such as ERP systems and Business Intelligence (BI). The analysis of the impact of integrating these tools reveals increased process automation and data centralization, allowing management controllers to focus on higher value-added analytical activities. However, despite these technological advancements, their involvement in strategic decision-making remains limited due to a persistent centralization of decision-making authority, thereby hindering the evolution toward a true Business Partner. |

Dans ce contexte le rôle du contrôleur de gestion évolue d'une fonction essentielle orientée vers la production des données financière et garant de l'information au sein de l'organisation vers un rôle plus analytique et stratégique, la disponibilité de l'information en temps réel renforce les exigences en matière de réactivité, de fiabilité et de capacité d'interprétation des données déjà existantes. Cette fonction a connu de multiples changements avec l'intégration des ERP et BI, Plusieurs recherches ont été menées sur ce sujet dans un contexte international, mais peu d'études ont abordé cette thématique dans le contexte marocain.

| Abstract: | The Blue Economy represents a sustainable and integrated approach to the utilization of ocean and marine resources, aiming to foster economic growth, enhance human livelihoods, and preserve the health of marine ecosystems. As oceans play a critical role in global food security, transportation, energy production, and climate regulation, ensuring their sustainable management has become a global priority. In recent years, rapid advances in Information Technology (IT) have played a transformative role in reshaping how marine resources are monitored, managed, and utilized. Technologies such as big data analytics, artificial intelligence, satellite systems, and the Internet of Things enable real-time data collection, predictive modeling, and informed decision-making across marine sectors. This article explores the intersection between the Blue Economy and Information Technology by highlighting key digital tools, real-world applications, as well as the benefits and challenges associated with digital transformation. It argues that embracing digital innovation is essential for achieving a sustainable, resilient, and inclusive Blue Economy capable of addressing environmental pressures while supporting long-term economic development. |
