Le domaine public
No full textLe domaine public est une vénérable institution du droit administratif des biens. Lointain héritier du domaine de la Couronne, il naît après la Révolution de l’impossible divorce entre la propriété et la puissance publique. Il regroupe les immeubles et les meubles appartenant aux personnes publiques et qui, en raison de leurs caractéristiques ou de leur affectation à l’intérêt général, ne sont pas susceptibles de propriété privée. Servant à l’exercice du pouvoir et à l’exécution des services publics, il est aussi quotidiennement utilisé par les membres du public lorsqu’ils s’y déplacent, manifestent, pratiquent leur culte ou exploitent une activité économique.
Durant le XXe siècle, les juges et le législateur font évoluer son régime juridique – la domanialité publique –, afin de concilier les logiques de protection et de valorisation. Désormais pleinement innervé par la propriété publique, il fait montre de vitalité pour relever, avec plus ou moins de réussite, les défis de sa modernisation, de son européanisation et du respect des droits, libertés et intérêts de ses utilisateurs.
Ce livre propose de considérer le domaine public comme une catégorie de biens d’exception, auxquels s’applique un régime juridique original et exorbitant
The Infinite Alphabet and the Laws of Knowledge
No full textWe all understand that knowledge shapes the fate of business and the growth of nations, but few of us are aware of the principles that govern its motion. The Infinite Alphabet unravels the laws describing the growth and diffusion of knowledge by taking you from a failed attempt to build a city of knowledge in Ecuador to the growth of China’s innovation economy. Through dozens of stories, you will learn why aircraft manufacturers in Italy began manufacturing scooters after the Second World War and how migrants like Samuel Slater shaped the industrial fabric of the United States.
Knowledge is the secret to the wealth of nations. But to understand it, we must accept that it is not a single thing, but an ever-growing tapestry of unique ideas, experiences and received wisdom. An Infinite Alphabet that we are only beginning to fathom
Data Sharing or Analytics Sharing ?
Get PDFData combination and analytics can generate valuable insights for firms and society as a whole. Firms can seize these opportunities by joining platforms that either allow them to access the data contributed by other firms or provide the result of the analytics performed on such data, depending on whether the platform adopts ''data sharing'' or "analytics sharing" technologies. The former technology enables firms to exploit their data endowment together with the data contributed by others, whereas the latter offers advantages in terms of privacy and security by reducing data transmission. We present a model that allows us to study the economic and managerial incentives generated by these technologies for both firms and a platform. First, we find that the platform chooses analytics sharing only when the security advantage of this technology is sufficiently large. Second, we show that analytics sharing results in a higher total data contribution than data sharing under general and reasonable conditions. Third, we determine the optimal data-combination technology from the perspective of consumers and discuss potential misalignments between the platform's and consumers' preferred technology. Our findings carry relevant policy and managerial implications, offering a pathway to enhance both data provision and security
A Dynamic Model of Predation
Get PDFWe study the feasibility and profitability of predation in a dynamic environment, using a parsimonious infinite-horizon, complete information setting in which an incumbent repeatedly faces potential entry. When a rival enters, the incumbent chooses whether to accommodate or predate it; the entrant then decides whether to stay or exit. We show that there always exists a Markov perfect equilibrium, which can be of three types: accommodation, monopolization, and recurrent predation. We then analyze and compare the welfare effects of different antitrust policies, accounting for the possibility that recurrent predation may be welfare improving
The Dark Side of Infrastructure: Roads, Repression, and Land in Authoritarian Paraguay
No full textTransportation infrastructure is associated with economic development, but it can also be used for social control and to benefit the governing elite. We explore the connection between the construction of road networks, state-led repression, and illegal land allocations in the longest dictatorship in South America: Alfredo Stroessner’s military regime in Paraguay. Using novel panel data from the truth and reconciliation commission, we show that proximity to newly constructed roads facilitated state-led repression, illegal allocation of agricultural plots to dictatorship allies, and hindered sustainable economic development in the following decades
Freidlin-Wentzell type exit-time estimates for time-inhomogeneous diffusions and their applications
Get PDFThis paper investigates the exit-time problem for time-inhomogeneous diffusion processes. The focus is on the small-noise behavior of the exit time from a bounded positively invariant domain. We demonstrate that, when the drift and diffusion terms are uniformly close to some time-independent functions, the exit time grows exponentially both in probability and in as a parameter that controls the noise tends to zero. We also characterize the exit position of the time-inhomogeneous process. Additionally, we investigate the impact of relaxing the uniform closeness condition on the exit-time behavior. As an application, we extend these results to the McKean-Vlasov process. Our findings improve upon existing results in the literature for the exit-time problem for this class of processes
