This paper analyses the statistical distribution of war size. We find strong support for a Pareto-type distribution (power law) using data from different sources (COW and UCDP) and periods. A power law describesaccurately the size distribution of all wars, but also the distribution of the sample...

The “Intended nationally determined contributions” (INDCs) communicated by both developing and developed countries represent a crucial element of the Paris agreement. This paper aims at analysing the INDCs submitted by Parties, through the different tools and approaches proposed by the...

The China - Raw Materials dispute recently arbitrated by the WTO opposed China as defendant to the US, the EU and Mexico as claimants on the somewhat unusual issue of export restrictions on natural resources. For the claimants, Chinese export restrictions on various raw materials, of which the...

Population movements will help people facing the impact of climate change. However, the resulting large scale displacements may also produce security risks for receiving areas. The objective of this paper is to empirically estimate if the inflows of climate-induced migrants increase the risk of...

We develop a strategic model of network interdiction in a non-cooperative game of flow. An adversary, endowed with a bounded quantity of bads, chooses a flow specifying a plan for carrying bads through a network from a base to a target. Simultaneously, an agency chooses a blockage specifying a...

In the environmental area, negotiated rulemaking, implementation, and compliance are proposed by their advocates as delivering two primary benefits: reduced rulemaking time and decreased litigation over a final agency rule. The experience to date, however, indicates that negotiated rulemaking...

Research on risk communication relates basic risk perception studies to the formulation of policies, the currently evolving legislation dealing with hazards, the key issues of public involvement, the risk and environmental management. Risk communication is a relatively new field based on a...

This paper focuses on the link between the group co-operation and the unilateral commitment behaviour of some countries in the presence of global environmental problems. As we consider that this last behaviour occurs when bargaining failed, we call it a precautious commitment. We also show that...
