| Abstract: | We study the duration of topics in economics research by looking at how much time passes between publication of textually similar papers. Using the corpus of abstracts of economics papers, as available from the RePEc dataset, we find that most papers match to papers from the same year, indicating strong common trends in the economics literature. Nevertheless, matches as long as 14 years apart are statistically significant, suggesting there are topics that last as long. Finally, the average duration of a match has dropped from around 4 years during 1990–2005 to about 1 year starting in 2010. |

| Abstract: | The academic evaluation of the publication record of researchers is relevant for identifying talented candidates for promotion and funding. A key tool for this is the use of the indexes provided by Web of Science and SCOPUS, costly databases that sometimes exceed the possibilities of academic institutions in many parts of the world. We show here how the data in one of the bases can be used to infer the main index of the other one. Methods of data analysis used in Machine Learning allow us to select just a few of the hundreds of variables in a database, which later are used in a panel regression, yielding a good approximation to the main index in the other database. Since the information of SCOPUS can be freely scraped from the Web, this approach allows to infer for free the Impact Factor of publications, the main index used in research assessments around the globe. |
