Does Cheaper, Faster, or Better Imply Sooner in the Timing of Innovation Decisions?
区分了研发活动中三种信息规模报酬（更便宜、更快、更好），并分析它们对企业创新决策时机的影响。结果发现，只有更准确的信息会促使决策提前，而更便宜的信息反而导致延迟。
A common myth/conception, based upon the notion of increasing returns to scale in R&D activity, is that large firms account for a disproportionate share of innovations. In this paper we consider three types of informational returns to scale (cheaper, faster, and better) and examine the impact of each on the timing of the firm's innovation decision. Contrary to popular conception, the decision is made later when information is cheaper, and the change in timing is unsignable in the case of faster arrival of information. Only more accurate (better) information leads to earlier decisions.
