We analyze non-cooperative commodity taxation in a symmetric twocountry trade model characterized by monopolistic competition and international firm and capital mobility. In this setting, taxes in one country affect foreign welfare through the relocation of mobile firms and through changes in the rents accruing to capital owners. With consumption-based taxation, these fiscal externalities exact...

The traveling salesman problem (TSP) is a challenging problem in combinatorial optimization. In this paper we consider the multiobjective TSP for which the aim is to obtain or to approximate the set of efficient solutions. In a first step, we classify and describe briefly the existing works, that are essentially based on the use of metaheuristics. In a second step, we propose a new method, call...

In this paper, we examine what kinds of social choice correspondences (SCCs) are implementable in Nash equilibria by “natural” mechanisms in divisible pure public goods economies. Then, we found conditions for SCCs to be Nash implementable by each of these four natural mechanisms. These characterizations of SCCs depend on the number of goods. First, regardless of the number of goods, the class ...

This paper analyzes the stability of the (Pareto efficient) nonsunspot equilibria as a function of the constraints faced by consumers in their ability to transfer wealth between states of nature. The nonsunspot equilibria are independent of the constraints since they can be identified to the equilibria of the associated certainty economy. It is shown that the equilibria that are stable for the ...

We analyze Pareto-efficient tax deduction rules for work-related expenses. Pareto efficiency dictates a strict rule marginal deductions along the income distribution. An immediate implication is recipe designing Pareto-improving reforms. apply our theory and simulate reform that introduces non-care household services (housekeeping, gardening, laundry) in United States. The combines rates betwee...

Many water resources systems are characterized by multiple objectives. For multiobjective optimization, typically there can be no single optimal solution which can simultaneously satisfy all the goals, but rather a set of technologically efficient noninferior or Pareto optimal solutions exists. Generating those Pareto optimal solutions is a challenging task and often difficulties arise in using...

With assets taken to be pools, rational expectations on their delivery rates are, as default is permissible in an economy and its penalty prescribed in terms of utility, indispensable to the existence of equilibrium. And the resulting equilibrium relies heavily on the prevailing penalty level. We propose, in this paper, a path-following algorithm for calculating the level of penalty that leads ...

This article describes a set function that maps a set of Pareto optimal points to a scalar. A proof is presented that shows that the maximization of this scalar value constitutes the necessary and sufficient condition for the function’s arguments to be maximally diverse Pareto optimal solutions of a discrete, multi-objective, optimization problem. This scalar quantity, a hypervolume based on a ...
