We estimate the effect of patent protection on follow-on investments in corporate scientific research. We exploit a new method for identifying an exogenous reduction in the protection a granted patent provides. Using data on public, research-active firms between 1990 and 2015, we find that firms...

This paper proposes a novel approach to measure disclosure in patent applications using algorithms from computational linguistics. Borrowing methods from the literature on second language acquisition, we analyze core linguistic features of 40,949 U.S. applications in three patent categories...

It is widely believed that the stock-market oriented US financial system forces corporate managers to behave myopically relative to their Japanese counterparts, who operate in a bank-based system. We hypothesize that if US firms are more myopic than Japanese firms, then episodes of financial...

We estimate and compare the production structures of the US, Japanese, and Korean total manufacturing sectors for the 1974-1990 period. We employ a translog variable cost function that includes such inputs as labor, materials, physical and R&D capital with the physical and R&D capital treated as...
