This paper examines the effects of credit constraints on aggregate innovation when firms face heterogeneous innovation costs and have differential access to credit. Better credit access affects aggregate innovation through (i) a direct effect by facilitating firms to innovate, (ii) a market share effect by encouraging low-cost firms to expand, and (iii) a value effect that increases competition and deteriorates high-cost firms’ innovation. We first develop a structural model featuring the above three channels. We then contrast this theory with the Chinese firm-level data documenting that Chinese state-owned enterprises are less constrained but face higher innovation costs than their private …

Stalking The Wild X Patent, Barbara J. Hampton

The limits of manual indexes and hand counts of entries made more sophisticated analyses impractical. Recently, a number of researchers have begun to apply scientometric methods to assess trends and causation in patterns of innovation in the United States by organizing data elements from patent documents. Although most patents are now searchable, fully digital records, the records of the earliest patents (1790–1836) were incinerated in a …
