The Impact of Finfluencers on Retail Investment (with Isaiah Hull)
Abstract: We examine the impact of financial influencers (``finfluencers'') on retail investment using real equity and derivative investments across four Nordic countries. Using an instrument that randomly assigns influencers to followers, we find the following: (1) Investors tend to follow influencers with high Sharpe ratios, frequent trades, a shared country of residence or language, and male gender. (2) Influencers affect followers' portfolios and trading behavior, particularly when they have a large following, a central network position, or participate in group discussions. This effect is strongest for investors who follow fewer influencers, female investors, and when trading passive funds.

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.

Faith and Financial Inclusion (with Madeleine Lindblad)
Abstract: We study how religion-compatible financial contracts shape financial inclusion by exploiting two plausibly exogenous shocks to the availability of Sharia-compliant mortgages in Denmark: the market introduction of a Sharia-compatible mortgage and a subsequent Supreme Court decision that prevented new registrations of these contracts. Using administrative registers and a difference-indifferences design comparing Muslim and non-Muslim immigrants, we find that the introduction increased the probability that a Muslim immigrant becomes a new mortgage borrower by 0.40 percentage points (25.6% relative to the pre-introduction mean), while the court ruling reduces take-up by about 0.10 percentage points. Mortgage access translates into economically meaningful improvements in economic well-being: treated immigrants become more likely to move to higher-income municipalities and exhibit higher deposits, total assets, financial assets, and net wealth. Our findings demonstrate that contract-form compatibility has first-order distributional consequences in credit markets and can materially expand financial inclusion.
