We study the efficiency of mechanisms for allocating a divisible resource. Given scalar signals submitted by all users, such a mechanism decides the fraction of the resource that each user will receive and a payment that will be collected from her. Users are self-interested and aim to maximize their utility (defined as their value for the resource fraction they receive minus their payment). Sta...

We consider the problem of efficient mechanism design for multilateral trading of multiple goods with independent private types for players and incomplete information among them. The problem is partly motivated by an efficient resource allocation problem in communication networks where there are both buyers and sellers. In such a setting, ex post budget balance and individual rationality are ke...

Current distributed computing infrastructures, such as peerto-peer networks, grids, and more recently clouds, make sharing and trading resources ubiquitous. In these large distributed systems, rational users are both providers and consumers of resources. Currently, there is growing interest in exploiting economic models for the allocation of shared computing resources that incentivize rational ...

Railway transportation plays an important role in the economic development of Iran. National Iranian Railways includes fifteen regional railways which operate independently, but under the supervision of National Iranian Railways Company. Evaluating the efficiency of regional railways is an important issue in Iran and is one of the bases for budget and resource allocation for further developmen...

Devolution has become a cornerstone of modern public-service management and this tendency is confirmed by several reforms carried out during the 1990s, namely in Europe, in the health sector. In this context, resource allocation decisions depend on multiple budget holders. Our objective is therefore to discuss possible consequences of relaxing the hypothesis of a single budget, which has been w...

In part due to the increasing demand for citizen participation in public decision processes, participatory budgets are becoming increasingly popular in many municipalities. As there is little methodology available for this type of activities and Information Technologies are scarcely used in them, we describe a prototype of a web-based decision support tool for participatory budget problems. We ...

Social exposure is one of the factors affecting the diffusion dynamics for Electric Vehicles (EV) uptake. It could be increased by advertising, but the effects of it change among different groups of people and residential zones. This study develops an optimization model that determines efficient allocation of advertising budget to zones. This model includes a dynamic market diffusion model (Str...
