How do investors decide? An interdisciplinary review of decision-making in crowdfunding

Crowdfunding is on the rise: its volume grew 1000% in only three years and is about to outpace worldwide venture capital spending. A quickly growing body of research is exploring the emerging crowdfunding phenomenon. While the literature offers a detailed and comprehensive picture of decision-making for traditional startup financing or bank loans, it does not provide a holistic understanding of decisions to invest in crowdfunded ventures. Many individual studies investigate isolated factors that influence investor decision-making in crowdfunding campaigns without integrating the findings regarding those influences. A comprehensive view of the relevant decision-making factors is necessary to build future research on and for practitioners to gain a better understanding of how investors choose. We conduct an interdisciplinary literature review to examine which factors influence the investment decisions in crowdfunding. From an analysis of 68 articles, we construct a comprehensive framework of relevant influence factors. Even though prior research covers many factors, others have received scant attention. Especially investors' cognitive features and the context in which the investment decision is made seem to strongly influence decisions but are scarcely researched. In addition, most reviewed studies focus more on individual factors and campaign success than underlying decision processes. To highlight novel factors of crowdfunding investment decisions, we compare decision-making in traditional investments, such as venture capital and bank loans, to crowdfunding. Our findings offer new avenues for research toward understanding how the shift induced by crowdfunding changes our choices and actions. The analysis should support the endeavor to build better theories and provide a basis for further social and technological development.
