ABSTRACT

With the wide-spread adoption of the Internet, websites that host job boards and CV banks have become important intermediaries in the labor market. Despite their popularity and conflicting evidence about their effectiveness, we know relatively little about the market for these websites and about their decision making. We address this void in two ways. First, we document how the market for employment websites evolved in the U.S. Second, we explore how a rapid expansion of Craigslist into local markets in the U.S. impacted market concentration and decision-making of competing websites.
