Geopolitical risk cannot be measured in a universal way. We develop new geopolitical risk indicators relying on local newspaper coverage to account for different perceptions. Using Russia as a case study, we demonstrate that geopolitical risk shocks identified from local news sources have...

In order to prepare and employ naval power and contribute to national defense, the Brazilian Navy, through its programs and projects, seeks to develop means of implementation of naval war operations and actions suitable for its main tasks - sea denial and control, and power projection. A...

Over the last decade, the defense industry has obtained relevance on Brazilian public policies. Departing from the premise that the success of this process requires not only that the Armed Forces have modern equipment and skilled military to operate them, but also that the country retains the...

This article demonstrates that the influence of government ideology on military expenditures is more nuanced than it was shown in previous research and using only aggregated military expenditures may provide ambiguous results. The disaggregation of military expenditures allows concluding that in...

We study information aggregation problems where to a set of measures a single measure of the same dimension is associated. The collection of measures could represent the beliefs of agents about the state of the world, and the aggregate would then represent the beliefs of the population....

This paper considers evolutionarily stable decisions about whether to initiate violent conflict rather than accepting a peaceful sharing outcome. Focusing on small sets of players such as countries in a geographically confined area, we use Schaffer's (1988) concept of evolutionary stability. We...

We study endogenous group formation in tournaments employing experimental threeplayer contests. We find that players in endogenously formed alliances cope better with the moral hazard problem in groups than players who are forced into an alliance. Also, players who are committed to expending...

Imitating the best strategy from the previous period has been shown to be an important heuristic, in particular in relatively complex environments. In this experiment we test whether subjects are more likely to use imitation if they are under stress. Subjects play a repeated Cournot oligopoly....

Can bombs and broadcasts instigate resistance against a foreign regime? In this paper, we examine the canonical case of bombing designed to undermine enemy morale-the Allied bomber offensive against Germany during World War II. Our evidence shows that air power and the airwaves indeed undermined...

I revisit the Rubinstein (1982) model for the classic problem of price hag- gling and show that bargaining can become a “trap,” where equilibrium leaves one party strictly worse off than if no transaction took place (e.g., the equilibrium price exceeds a buyer’s valuation). This arises...
