The Impact of Finfluencers on Retail Investment (with Isaiah Hull)
Abstract: We study financial influencers (finfluencers) and quantify their impact by combining novel data on real equity and derivative investments made by investors in four Nordic countries with a unique IV strategy that exploits the random assignment of influencers. We document the following findings. First, investors are more likely to follow influencers who have a high Sharpe ratio, execute more trades, live in the same country, or share the same language. Second, influencers' portfolio and trading choices have sizable impacts on their followers. Third, their influence is more pronounced when (1) they have more followers, are central in the network, and participate in more group discussions; (2) their followers are exposed to fewer influencers or are female; and (3) they are trading in passive funds. Last, we find suggestive evidence that influencers employed by the platform monetize their popularity to sell securities and generate trading volume.

Financing Suppliers (with Niklas Amberg and Tor Jacobson)
Abstract: Buyers and suppliers have diverging interests about trade-credit maturities: buyers desire long payment periods as a source of cheap funding, while suppliers prefer swift payments to avoid locking up scarce liquidity in idle assets. A fast-growing financial product innovation---supply-chain finance (SCF)---offers to resolve these diverging interests, but its net effect on suppliers is a priori unclear. We study the effects of SCF programs on suppliers using unique invoice-level data from a large Swedish bank. We find that SCF programs relax suppliers’ liquidity constraints and thereby enable them to grow their sales, employment, and investments.
