Abstract: Advertising plays a particularly crucial role in online marketplaces, where thousands of merchants offer similar products and compete for visibility and consumer attention. This study theoretically and empirically demonstrates that merchants on e-commerce platforms often engage in "underadvertising" due to financial constraints. By leveraging quasi-random variation in merchants' access to credit from a major platform lender, we establish that alleviating financial constraints leads to substantial increases in advertising expenditures, enhanced shop visibility among customers, and ultimately, accelerated sales growth. Notably, high-quality merchants with top customer ratings are especially likely to utilize platform credit to invest in advertising.
