Research Scientist Productivity and Firm Size: Evidence from Panel Data on Inventors

It has long been recognized that worker wages and possibly productivity are higher in large firms. Moreover, at least since Schumpeter (1942) economists have been interested in the relative efficiency of large firms in the research and development enterprise. This paper uses longitudinal worker-firm-matched data to examine the relationship between the productivity of workers specifically engaged in innovation and firm size in the pharmaceutical and semiconductor industries. In both industries, we find that inventors’ productivity increases with firm size. This result holds across different specifications and even after controlling for inventors’ experience, past productivity, the quality of other inventors in the firm, and other firm characteristicsPatents; Innovation; Labor productivity; Research; Firm size

Authenticity in Finitude: Interpretation of Heidegger

This paper organizes Martin Heidegger’s argument for authenticity in Being and Time into a two-step process with two binaries. The first binary is an interpretation for the world, with what Heidegger calls ‘ready-to-hand’ coming prior to ‘present-at-hand.’ The second binary is an interpretation for the self, where he distinguishes the ‘authentic self’ from the ‘they-self.’ With human existence represented as Dasein, or Being-there, Heidegger paints a path for authenticity within the world of relations and the world we live with others. For coherence between the two binaries, we need a reinterpretation of time. The second section of this paper focuses on Dasein’s temporality and how the two binaries could be maintained with their seemingly contradictory relationships to time. The contradiction is resolved by having authentic Dasein’s temporality take priority over the dominant conception of objective linear time. Through this, Heidegger’s unique account of authenticity in finitude is made clear

The Influence of University Research on Industrial Innovation

We use U.S. patent records to examine the role of research personnel as a pathway for the diffusion of ideas from university to industry. Appearing on a patent assigned to a university is evidence that an inventor has been exposed to university research, either directly as a university researcher or through some form of collaboration with university researchers. Having an advanced degree is another indicator of an inventor's exposure to university research. We find a steady increase in industry's use of inventors with university research experience over the period 1985-97, economy wide and in the pharmaceutical and semiconductor industries in particular. We interpret this as evidence of growth in the influence of university research on industrial innovation. Moreover, during this period we find that firms with large research operations in both industries, and young and highly capitalized firms in the pharmaceutical industry, are disproportionately active in the diffusion of ideas from the university sector. Finally, we find that the patents of firms that employ inventors with university research experience are more likely to cite university patents as prior art, suggesting that this experience better enables firms to tap academic research.

Research Scientist Productivity and Firm Size: Evidence from Panel Data on Investors

It has long been recognized that worker wages and possibly productivity are higher in large firms. Moreover, at least since Schumpeter (1942) economists have been interested in the relative efficiency of large firms in the research and development enterprise. This paper uses longitudinal worker-firm-matched data to examine the relationship between the productivity of workers specifically engaged in innovation and firm size in the pharmaceutical and semiconductor industries. In both industries, we find that inventors' productivity increases with firm size. This result holds across different specifications and even after controlling for inventors' experience, education, the quality of other inventors in the firm, and other firm characteristics. We find evidence in the pharmaceutical industry that this is partly accounted for by differences between how large and small firms organize R&D activities.Patents; Innovation; Labor productivity; Research; Firm size

International Knowledge Flows: Evidence from an Inventor-Firm Matched Data Set

We describe the construction of a panel data set from the U.S. patent data that contains measures of inventors' life-cycle R&D productivity--patents and patent citations. We match the data set to information on the U.S. pharmaceutical and semiconductor firms for whom they work. In this paper we use these data to examine the role of research personnel as a pathway for the diffusion of ideas from foreign countries to U.S. innovators. In particular, we find in recent years an increase in the extent that U.S. innovating firms collaborate with or employ researchers with foreign experience. This increase appears to work primarily through an increase in U.S. firms' employment of foreign-residing researchers; the fraction of research-active U.S. residents with foreign research experience appears to be falling, suggesting that U.S. pharmaceutical and semiconductor firms are increasingly locating operations in foreign countries to employ such researchers, as opposed to such researchers immigrating to the U.S. to work. In addition, we investigate which U.S. firms conducting R&D build upon innovations originating abroad. We find that employing or collaborating with researchers who have research experience abroad seems to facilitate the use of output of non-U.S. R&D. We also find that in the semiconductor industry smaller and older firms, and in the pharmaceutical industry, younger firms are more likely to access foreign R&D output.

Goryeoyang and Mongolpung in the 13 th – 14 th centuries

The present paper gives an overview of cultural exchanges between Goryeo and Yuan China in the 13th and 14th centuries when Goryeo was under the rule of the Yuan Dynasty. The article discusses the historical background of the cultural trends dubbed Goryeoyang (高麗樣) and Mongolpung (蒙古風) which had a great deal of influence on both peoples in many spheres of life, from everyday life to politics. By taking into account a wide variety of examples including fashion, food, lifestyle as well as the linguistic dimension, many similar customs and traditions can be identified between the two nations
