March 2017Corporate Culture: Evidence from the Field
with John R. Graham, Campbell R. Harvey, Shivaram Rajgopal: w23255
Does corporate culture matter? Can differences in corporate culture explain why similar firms diverge with one succeeding and the other failing? To answer these questions, we use a novel survey and interview-based analysis of 1,348 North American firms. Over half of senior executives believe that corporate culture is a top-three driver of firm value and 92% believe that improving their culture would increase their firm's value. Surprisingly, only 16% believe their culture is where it should be. Executives link culture to ethical choices (compliance, short-termism), innovation (creativity, taking appropriate risk), and value creation (productivity, acquisition premia). We assess these links within a framework that implies cultural effectiveness depends on interactions between cultural value...
November 2013Patent Value and Citations: Creative Destruction or Strategic Disruption?
with David S. Abrams, Ufuk Akcigit: w19647
Prior work suggests that more valuable patents are cited more and this view has become standard in the empirical innovation literature. Using an NPE-derived dataset with patent-specific revenues we find that the relationship of citations to value in fact forms an inverted-U, with fewer citations at the high end of value than in the middle. Since the value of patents is concentrated in those at the high end, this is a challenge to both the empirical literature and the intuition behind it. We attempt to explain this relationship with a simple model of innovation, allowing for both productive and strategic patents. We find evidence of greater use of strategic patents where it would be most expected: among corporations, in fields of rapid development, in more recent patents and where divisiona...
