“…A more granular examination of individual investor decisions requires investigation at the micro level. The rapidly growing body of empirical literature on the motivations of SI investors typically focuses on distinct sub-samples of the population, using either experimental settings (Gutsche and Ziegler 2016;Barreda-Tarrazona, Matallín-Sáez, and Balaguer-Franch 2011;Glac 2009;Webley, Lewis, and Mackenzie 2001), survey-based data (Brodback, Guenster, and Mezger 2019;Dor-fleitner and Utz 2014; Berry and Junkus 2013), administrative investor portfolio data, or a combination thereof (Bauer, Ruof, and Smeets 2019;Riedl and Smeets 2017;Borgers and Pownall 2014). Experimental research designs testing investment decisions in a laboratory setting aim to eliminate social desirability biases of survey-based research, while they may also encounter limitations in terms of generalizability, framing biases and social desirability bias caused by the experimental setting itself (Levitt and List 2007).…”
