Crowdfunding constitutes one of the financial solutions to achieve the sustainable development goals, by fostering innovation and economic growth. This paper conducts an empirical two-country analysis (the UK and Spain) of characteristics of successful offerings to assess the distribution of overfunding in equity crowdfunding. Unlike previous research, which has usually comprised campaigns posted on single-country portals, our study is based on an international leading platform operating with country-differentiated websites, Crowdcube. Such an approach allows us to identify influential factors which are dependent on country and, simultaneously, to control for those platform-related factors. To focus on the overfunding distribution, a quantile regression methodology is adopted for a total sample of 299 overfunded campaigns from 2015 to 2018. Overall, empirical results show that the effects of key campaign features (equity, voting rights and social capital) are stronger and more significant at the 75th and 90th quantiles for the overfunding level and the number of investors. Furthermore, we find significant differences across countries, which persist along the distributions of overfunding. Yet, interestingly, between-country differences in overfunding level vanish for the technological sector. Our research provides further insights into the relation between equity crowdfunding and sustainable finance.

In this paper, we investigate rewards-based crowdfunding as an innovative financing form for startups and firms. Based on game-theory models under asymmetric information, we test research hypotheses about the positive effects of two main campaign features: funding target and number of rewards. Furthermore, we examine how and when these characteristics are effective in attracting crowdfunders, by signaling high-quality projects (target) and by pricing according to backers’ preferences (rewards). Conditional process analysis is applied to a dataset of 1613 projects launched on the Spanish platform Verkami from 2015 to 2018. As expected, our study shows that market size is positively influenced by the target and the number of rewards, separately. Further analysis gives some interesting findings. Firstly, we find significant and positive mediating roles of social networks (in the relationship between target and market size) and of backers’ preferences (between rewards and market size). Secondly, the main orientation of a campaign, commercial or social, is relevant to explain previous relationships. While high funding targets are more effective in commercial projects, a high number of rewards is more effective in the social projects. This research provides new insights into the design of optimal crowdfunding, with theoretical and empirical implications.
