Søren Johansen and Katarina Juselius: A Bibliometric Analysis of Citations through Multivariate Bass Models

Abstract

We showcase the impact of Katarina Juselius and Søren Johansen’s contribution to econometrics using bibliometric data on citations from 1989 to 2017, extracted from the Web of Science (WoS) database. Our purpose is to analyze the impact of KJ and SJ’s ideas on applied and methodological research in econometrics. To this aim, starting from WoS data, we derived two composite indices whose purpose is to disentangle the authors’ impact on applied research from their impact on methodological research. As of 2017, the number of applied citing papers per quarter had not yet reached the peak; conversely, the peak in the methodological literature seem to have been reached around 2000, although the shape of the trajectory is very flat after the peak. We analyzed the data using a multivariate dynamic version of the well known Bass model. Our estimates suggest that the methodological literature is mainly driven by “innovators”, whereas “imitators” are relatively more important in the applied literature: this might explain the different location of the peaks. We also find that, in the literature referring to KJ and SJ, the “cross-fertilization” between methodological and applied research is statistically significant and bi-directional.

GHG Emissions and Economic Growth in the European Union, Norway, and Iceland: A Validated Time-Series Approach Based on a Small Number of Observations

“…The data were collected separately in aggregated values for the EU-27 countries and the EFTA-2 countries (Alghalith 2007;Archontakis and Mosconi 2021;Baxa et al 2015;Eurostat 2022). Additionally, the Granger representation theorem was applied to the studied relationships between researched variables and defined hypotheses:…”

Technical Analysis of Tourism Price Process in the Eurozone

“…This rare study deals technically with normalities in a time-series (Kongsted 2005;Juselius 2021;Vougas 2021). Econometricians (Johansen 2019) usually define and prove a purely theoretical treatment of this system (Archontakis and Mosconi 2021;Franchi and Paruolo 2021). In addition, this study contributes to a step-by-step process to show the timeseries technicalities, similar to Pacifico (2021), on volatilities.…”

“…The guiding theory used for this study comes from the paper by Archontakis and Mosconi (2021) that is based on the tradition of Katarina Juselius and Søren Johansen.…”

“…The main novelty and contribution are in the empirical testing of the hypotheses set with the applied cointegration approach (Archontakis and Mosconi 2021) to seasonally determined tourism prices by the imperative transformation of integrated nominal to real data vector in the VAR approach. The empirical part of this article introduces the analysis of the transmission of the eurozone price indices in the hospitality industry on Slovenian ones as its member state.…”

“…Shocks in a model of the observed time-series can be used to test a theoretical-conceptual model (Camarero et al 2020). This approach can work well as long as critical features of the theory are preserved to confirm both the theoretical model and the model of the true variables (Hoover and Juselius 2015;Archontakis and Mosconi 2021).…”
