This paper contributes a new idea for exploring research funding effects on scholar performance. By collecting details of 9,501 research grants received by principal investigators from universities in the U.S. social sciences from 2000 to 2019 and data on their publications and citations in the Microsoft Academic Graph and Web of Science bibliographic collections, we build a novel dataset of grants and article counts, citations, and journal CiteScore. Based on this dataset, we first introduce three instrumental variables (IVs) suitable for isolating endogeneity issues in the study of competing grant effects, namely scholars’ political hegemony in academia, imitation isomorphic behavior among scholars, and project familiarity. Then, this study explains the research funding effects by combining the three IVs with a two-stage least square (2SLS) model. Also, we provide validity and robustness tests of these three IVs and research funding effects. We find that our IVs serve the function of exogenizing and isolating endogeneity in capturing the research funding effect. Empirical findings show that receiving research funding increases a scholar’s research output and impact. While research funding doesn't significantly increase high CiteScore publications, it reduces submissions to low-prestige journals, reshaping journal selection strategies and raising the “floor” of academic performance.

The citation impact of a scientific publication is usually seen as a one-dimensional concept. We introduce a multidimensional framework for characterizing the citation impact of a publication. In addition to the level of citation impact, quantified by the number of citations received by a publication, we also conceptualize and operationalize the depth and breadth and the dependence and independence of the citation impact of a publication. The proposed framework distinguishes between publications that have a deep citation impact, typically in a relatively narrow research area, and publications that have a broad citation impact, probably covering a wider area of research. It also makes a distinction between publications that are strongly dependent on earlier work and publications that make a more independent scientific contribution. We use our multidimensional citation impact framework to report basic descriptive statistics on the citation impact of highly cited publications in all scientific disciplines. In addition, we present a detailed case study focusing on the field of scientometrics. The proposed citation impact framework provides a more in-depth understanding of the citation impact of a publication than a traditional one-dimensional perspective.
