In a stylized model of international trade, firms in the North indirectly export second-hand products to a representative firm in the South to be reused as intermediate goods, with potential trade gains. The level of reusability of waste products is a crucial choice variable in the North. This...

Constructing a dynamic game model of trade of an exhaustible resource, this paper compares feedback Nash and Stackelberg equilibria when the exporting country sets quantity rather than price. We consider two different leadership scenarios: leadership by the importing country, and leadership by...

Does a country strictly gain if it acts as a leader in a resource market under bilateral monopoly? Using differential games, we show that the answer is "yes"" when leadership can be exercised globally (global Stackelberg leadership), but possibly ""no"" when it is exercised only at each stage...

This paper proposes three analyses of the tradeoff mechanism between ecotax and carbon credit. Our wish is to compare the ecotax level with the carbon credit price, subject to the minimization of the cost inherent to emissions. We redefine the calculus equations of the firm profit, in which we...

This paper proposes a new welfare criterion which satisfies three desiderata: strong sensitivity to the least advantaged, sensitivity to the present, and sensitivity to the future. We develop necessary conditions for optimal paths under this new criterion, and demonstrate that, in a familiar...

In the context of bilateral bargaining,we deal with issue linkage by developing a two-issue-two-players cooperative bargaining model. The axioms we propose focus on the role of the disagreement points. A family of bargaining rule stands out: the monotonic equal net ratio solutions. These...

The evaluation of development processes and of public policies often involves comparisons of social states that differ in income distributions, population sizes and life longevity. This may require social evaluation principles to be sensitive to the quality, the quantity and the duration of...

We analyze 17 studies of the use of sustainable development indicators (SDI) in an urban setting. The analysis reveals a lack of consensus not only on the conceptual framework and the approach favored, but also on the selection and optimal number of indicators. First, by performing different...
