The aggregation of polymer colloids is studied in processes induced at high ionic concentration. Cluster-size distributions are measured with a single-cluster light scattering instrument constructed by our team. A brief description of the instrument is given and its proper performance is...

In this paper, we present a stochastic model for obtaining the time evolution of the cluster size distribution for systems following coupled aggregation and sedimentation processes. Both, diffusion-limited cluster aggregation conditions and reaction limited cluster aggregation conditions are...

In this paper, we focus on the adverse selection issue that prevails when the regulator is not able to observe the type of the abatement costs of the firms. The regulator decides the total level of emission that minimizes the expected social cost of pollution and she sells them to the firms. In...

The first-order approach is a technical shortcut widely used in agency problems. The best known set of sufficient conditions for its validity are due to Mirrlees and Rogerson and require that the distribution function is convex in effort and has a likelihood ratio increasing in output. Only one...

The liability and compensation for the damage caused by maritime oil spills have been regulated by the 1992 International Convention on Civil Liability for Oil Pollution Damage (1992 Civil Liability Convention) and the 1992 International Oil Pollution Compensation Fund Convention (1992 IOPC...

[fre] Bien que la France ait écarté jusqu’ici l’idée de recourir à des instruments incitatifs pour réduire la pollution diffuse aux nitrates, cet article revient sur le potentiel de ces instruments tels qu’ils ont été employés par certains de nos voisins européens ou, à défaut,...
