Abstract: How does market concentration affect aggregate productivity? We study this by incorporating the role of demand in a dynamic model of granular firms that expand demand through marketing. Firms market due to high productivity or accumulated size from the past; this second force generates path dependency and persistent misallocation. Calibrating the model to firm-level price and sales data, we find that demand drives the majority of firm size growth, and there is a sizable mismatch with productivity. Endogenous marketing significantly slows down the catching up of aggregate productivity to firm-level productivity, exacerbating concentration and misallocation. Standard policies that aim to correct static markup distortions can exacerbate the dynamic misallocation between demand and productivity.
