Searching for partners involves informational persistence that reduces future traders' matching probability. In this paper, traders who are no longer available but who left tracks on the market are called phantoms. We examine a discrete-time matching market in which phantoms are a by-product of...

We investigate the relationship between competition and firm specialization in the venture capital (VC) market. Staged financing motivates VC firms to fund entrepreneurs in various states of maturity: startup/seed, early, growth, and so forth, and leads to stage specialization. Contrary to the...
