Security as an objectively existing quality which can be discussed in innumerable ways, but it may hardly be ignored and its significance (let alone its existence) may hardly be doubted. Security is a fundamental human need which is a subject of our efforts for its satisfaction and its chronic...

We experimentally test the social motives behind individual participation in intergroup conflict by manipulating the framing and symmetry of conflict. We find that behavior in conflict depends on whether one is harmed by actions perpetrated by the out-group, but not on one's own influence on the...

Solar geoengineering has received increasing attention as an option to temporarily stabilize global temperatures. A key concern surrounding these technologies is that heterogeneous preferences over the optimal amount of cooling combined with low deployment costs may allow the country with the...

This paper analyses, within a standard International Environmental Agreement game, the effect of the introduction of adaptation on climate negotiation. The model expands the existing literature by considering a double relation between the two strategies. The common assumption that higher...

We examine in detail the implementation of a project that is non-harmful for all agents as well as a project that is harmful for some agents through a unit-by-unit contribution mechanism. For a project that is non-harmful for all agents, efficient implementation is supported at one regular Nash...

What do climate change, global financial crises, pandemics, and fragility and conflict have in common? They are all examples of global risks that can cross geographical and generational boundaries and whose mismanagement can reverse gains in development and jeopardize the well-being of...
