The economic effects of international trade in armaments in the major western industrialized and developing countries†

We have used the Michigan Model of World Production and Trade to assess the impact of exports and imports of armaments (based on 1980 data) on sectoral trade and employment and other economic variables in the major Western trading countries. If the United States were to place a unilateral embargo on its arms exports and imports, we calculate that it would experience a comparatively small amount of employment displacement in the aggregate and that most of this displacement would occur in the transport equipment and electric machinery sectors. If all the major Western countries were to place a multilateral embargo on their arms trade, the sectoral effects on the United States would be similarly small. But the sectoral effects in several other industrialized and developing countries measured as a percentage of sectoral employment, would be larger, indicating potential short‐run adjustment problems in labor markets in some cases.

A case study in bio-inspired engineering design: defense applications of exoskeletal sensors

As part of a bio-inspired design process, the authors examine exoskeletal sensors found in insects and their potential application to armor and hardened buildings. In this way, the outer hardening of a structure or vehicle would not limit the ability of occupants to arrive at an actionable picture of the outer environment. To this end, various sensor modalities employed by insects are compared and contrasted with their current human-engineered equivalents. In several sensing modalities, biosensors perform better, are smaller, and more energy efficient than human-engineered equivalents. They note that biological designs tend to employ non-linear response to signal amplitude and respond with heightened sensitivity over a greater dynamic range of signals than human-engineered sensors. The insect biological sensors have structural and mechanical innovations that preserve the protective capacity of the exoskeleton.
