June 10, 2016 Abstract Research on corporate innovation often focuses on firms with positive US patent activity and reported R&D, thereby excluding over 90% of the firms in Compustat. By exploiting data from 30 global patent offices, we investigate the nature of missing innovation data in the US and around the world. We find systematic and predictable patterns across firms and countries for mis...

We inventory more than 150 studies of distributive politics in more than three dozen countries other than the United States. We organize existing studies under two theories: theories of democratic accountability and theories of government responsiveness. Studies that concern democratic accountability conceptualize distributive allocations as attempts by politicians to protect themselves elector...

Nutritional rickets is a major public health problem in many countries of the world. The disease is characterized by deformities of the long bones, enlargement of the wrists and costochondral junctions, hypotonia and, in infants, craniotabes and delayed fontanelle closure. Predominantly caused by severe vitamin D deficiency, rickets can also be associated with hypocalcemic seizures and cardiac ...

A common notion of vision, consistent with this excerpt from the first paragraph of David Marr’s seminal book [1], is gained by considering the predicament of a person with a searchlight placed in a pitch-dark room full of unfamiliar furniture. One would hope that, by swinging the beam around, the observer will be able to recognize the objects present in the room (a cat here, an aquarium there,...

In this paper, we obtain new oscillation criteria for second-order half-linear impulsive differential equations having fixed moments of impulse actions. We also generalize the results to nonlinear impulsive equations. The oscillation criteria obtained in this paper can be considered as extensions of those given by Leighton, (J. London Math. Soc. 27 (1952)), Coles (Proc. Amer. Math. Soc. 19 (196...

We use a dynamic model of of financing decisions to measure agency conflicts at the firm level for a large panel of 12,652 firms from 14 countries. Our estimates show that agency conflicts are large and vary significantly across firms and countries. Differences in agency conflicts are largely due to differences in firm-level governance, ownership concentration, and other firm characteristics. T...

We receive bits of information every day. They come to us in a stream. When we listen music, read book, or solve math problem stream musical bits, word bits. Our minds arrange that into network. A network links together like notes, syllables, concepts. Networks help organize and anticipate what is coming next. In this article, ask two questions about how our build networks: First, are some netw...
