Abstract

We study how competition among investors affects the efficiency of capital allocation, the speed of capital, and welfare. In our model, investors learn about other entrants in a fully flexible way. We find that competition increases the speed of capital, but does not necessarily improve the efficiency of capital allocation: there is persistent over- or underinvestment. As speed is a by-product of costly over-learning, increasing competition decreases welfare. We describe how the speed of capital and the level of over- or underinvestment depend on market and investor characteristics. With investors of heterogeneous skills, more sophisticated investors might harm welfare.
