Production of output and ideas: efficiency and growth patterns in the United States
使用前沿技术联合估计美国各州的产出生产与知识生产过程，发现各州在产出生产上效率较高，但在创新资源转化为新知识的过程中存在更多浪费，且富裕州并不比贫困州更高效。
Production of output and ideas: efficiency and growth patterns in the United States. Regional Studies. This paper examines efficiency and growth patterns in the production of output and ideas in the United States. It employs frontier techniques and jointly estimates the production of output and the production of ideas. We find states to be particularly efficient in the use of their inputs in the production of output process, whereas there is more waste in the use of innovation resources to produce new knowledge. The results do not lend support to the common perception that richer (more innovative) states are more efficient than less rich (less innovative) states for every dollar spent.
