| Abstract: | We analyze the distributions of paper-paper and paper-patent citations and estimate the relationship between them, based on a sample of 4,763 published papers for which the corresponding authors were among the top 100 researchers in the life and medical sciences in Japan. We find that paper-paper citations peak at an average of 4 years after the publication of a paper, while the corresponding lag for paper-patent citations is 6 years. Although there is a time lag before papers can be put to practical use, this lag has shortened in recent years. Moreover, the quality of a paper is important for being cited by a patent, and a paper’s quality increases the number of paper-patent citations. In addition, we show that an inverse U-shaped relationship exists between the amount of research grant funding and research quality, and we can derive the efficient amount of research grant funding that maximizes research quality. We find that the relationship between research quality and the total number of papers written by the researcher(s) is U-shaped, and we derive the number of papers that minimizes research quality |

| Abstract: | We investigate whether a creaming off of highly able students from Dutch universities is taking place. Therefore, we examine the relation between ability and the destination of recent graduates of Dutch universities. Students can choose to continue their academic career by investing in a PhD degree instead of working, taking into account that both options can be realized in the Netherlands as well as abroad. We also investigate whether these choices are affected by the climate in certain fields of study and universities. Using a data set of workers and PhD students who recently graduated from Dutch universities two probit equations are estimated simultaneously, one for the migration decision and one for the choice between working and pursuing a PhD. Our findings indicate that highly able graduates are significantly more likely than average graduates to go abroad. They invest more often in a PhD programme, which is positively correlated with their likelihood to go abroad. In addition, the climate promoting going abroad and starting PhD study is shown to have positive effects on the odds of going abroad and participating in a PhD programme. This particularly holds for the highly able. |
