dc.description.abstractOver the last decades passive investment products have continuously increased their market share. The efficiency of financial markets is identified to be the main reason for this development. We propose a theoretical model framework which illustrates that the causality can also be reversed, i.e. shows that the efficiency of markets might improve as consequence of passive investment. We analyze a market in which agents process noisy correlated signals and trade a single asset, and we derive a closed-form expression for their expected payoffs. For competitive market makers, we provide a unique pricing expression which leads to a fully-revealing equilibrium and efficient markets. On the contrary, we show that a monopolistic market maker induces frictions in the price-discovery process with partially-revealing equilibria and inefficient markets. Agents with highly correlated noise improve their expected payoffs by reducing the information processing activity, and by doing so they even increase market efficiency.en_US
