| Homeland security against possible terrorist attacks involves making decisions under true uncertainty. Not only are we ignorant of the form, place, and time of potential terrorist attacks, we are also largely ignorant of the likelihood of these attacks. In this paper, we conceptualize homeland security under true uncertainty as society's immunity to unacceptable losses. We illustrate and analyze the consequences of this notion of security with a simple model of allocating a fixed budget for homeland security to defending the pathways through which a terrorist may launch an attack and to mitigating the damage from an attack that evades this defense. In this problem, immunity is the range of uncertainty about the likelihood of an attack within which the... |

| This paper explores whether natural resource abundance leads, other things equal, to slower growth rates. We distinguish between natural resource dependence (RD) and the natural resource endowment (RE). We estimate three models, using World Bank data on national capital stocks. In a one-equation model we show that RD has a negative effect on growth rates, apparently confirming the main results of the resource "curse" literature. RE, however, has a positive impact on growth. We then estimate a two-equation model, in which the impacts of RE are much weaker. Finally, we estimate a three-equation model, in which the impacts of natural resources on growth disappears. |
