<jats:p>Crowdfunding platforms are peer-to-peer two-sided markets that enable amateur entrepreneurs to raise money online for their ventures. However, in allowing practically anyone to enter, such platforms enable opportunistic suppliers to flood the market with offerings, many of which are of low quality. This situation creates choice overload for potential backers and may thus influence their investment decisions. To empirically study the implications of this phenomenon for crowdfunding performance, we use a quasi-natural experiment in the form of an exogenous media shock that occurred on https://Kickstarter.com. The shock was followed by a sharp increase in the number of campaigns, particularly low-quality ones, offered on the supply side of the market; no such increase was observed on the demand side of the market. These unique conditions enable us to estimate how crowdfunding platforms are affected by the presence of an atypically large number of low-quality campaigns, while controlling for fluctuations in demand. We use two identification strategies, which enable us to control for changes in quality, to show that an increase in low-quality supply significantly decreases the…
