Innovation in a Shrinking World
This paper explores the implications of reductions in tariffs or transport costs on the rate of innovation in a quality ladders model where Þrms from both countries innovate. If a country raises its tariffs, its wage rises relative to the other country and its Þrms become technology leaders for a larger fraction of products, but the aggregate rate of innovation falls. If transport costs fall sy...

متن کاملShrinking the Oculomotor World Using Global Saccadic Adaptation
Visual perception depends on saccadic eye movements to bring objects of interest onto the fovea. To achieve this with continuing efficiency, the oculomotor system needs to calibrate saccades so that they reliably land on their targets. Saccades can be made to systematically miss their target by shifting its position during the saccade, when the observer is oblivious to such a change. As a resul...
متن کاملShrinking a carbon nanotube.
We report a method to controllably alter the diameter of an individual carbon nanotube. The combination of defect formation via electron irradiation and simultaneous resistive heating and electromigration in vacuum causes the nanotube to continuously transform into a high-quality nanotube of successively smaller diameter, as observed by transmission electron microscopy. The process can be halte...
