The emergence and growth of online labor markets have enhanced the efficiency in labor sourcing. Meanwhile, the short-term work relationship online leads to a potential “cut corners” behavior. To reduce the risks of receiving sub-par work from a bad hire, a new contest-based scheme is introduced in online labor markets, which allows employers observe and compare work outcomes from various workers before paying for the final selection. However, the actual effectiveness of contest-based scheme has not been proved yet in online labor market context, especially comparing with that of contract-based scheme. This study aims to examine whether tasks performed under contests are of a comparable (or superior) work quality relative to tasks governed by contractual schemes that are traditionally used in these online markets. Using data from a large online labor market that utilizes both contest-based and contract-based schemes, we empirically compare the job performance under these two schemes. Our results suggest that jobs posted under contracts tend to generate higher perceived work quality compared to those posted under contests. Furthermore, we investigate and find that the reduced flow of information and increased “copying” behaviors are two main reasons that cause the ineffectiveness of contest-based scheme in online labormarkets.
