Research Summary: Our study shows how institutional intermediaries established to foster the creation of new firms might hinder new firm growth instead. We show that intermediaries can reduce new firm growth rates due to institutional conflict. To analyze this idea, we examine the setting of junior stock exchanges, which are commonly formed to facilitate entrepreneurial growth. The introduction of these exchanges focused investment into new technology firms, reduced investment in other sectors, and led to diminishing new firm growth. Our findings demonstrate how institutional conflict causes unintended effects and reveals the complexity of influencing entrepreneurship with institutional intermediaries. Managerial Summary: Investors and entrepreneurs face uncertainty when deciding what firms to start and fund. We show that an intermediation effort to make entry easier for entrepreneurs increases the uncertainty that entrepreneurs and investors face. For investors, the enthusiasm for technology firms engendered by the new exchange can motivate investment in marginal firms to maintain as desired deal flow. However, lower firm growth and less liquidity in the future is likely. For entrepreneurs, our results indicate that it is more challenging to manage technology firm growth as well as there is potential opportunity to investigate other industries. Finally, for policymakers and supporters of the new exchanges, our results imply that investment flows are altered as intended, but unless listing standards remain high, the virtuous cycle of † The authors dedicate this work to the memory of Dr. William Miller-a mentor and friend to both of us whom we deeply miss.
