The tradeoff between production and safety investment is scrutinized for two agents who convert resources into production and safety investment while simultaneously exchanging goods voluntarily. We quantify how two Cobb-Douglas parameters, one scaling production versus safety, and the other...

The ratio of within-group to between-group fighting is shown to be unrealistically high for the collective rent seeking model when agents exert two efforts i.e. within-group and between-group efforts. The ratio is more realistic for the production and conflict model. Six economics examples...

A company allocates a resource between safety effort and production. The government earns taxes on production. The disaster probability is modeled as a contest between the disaster magnitude and the two players’ safety efforts. The model illustrates that safety efforts are strategic...

In Hirshleifer's (1995) model for unitary actors, combined fighting/production abruptly breaks down when inter-group decisiveness of fighting is above a certain value (above one) or income requirements are not met. Accounting for the collective action problem, this article gives the opposite...

A two-period exchange model is developed where production decisions in the first period determine the amount of resources available in the second period. Each agent allocates resources to defend its production and attack the production of the other agent. Production, conflict and exchange occur...
