Referral hiring and wage formation in a market with adverse selection
研究了员工推荐招聘如何影响劳动力市场效率，发现推荐能缓解逆向选择并提高工资，但雇主风险规避和招聘动态性仍导致市场效率低下。
The widespread use of employee referrals raises questions regarding how they affect labor market outcomes. Does referral hiring lead to a more efficient allocation of workers compared to when hiring is possible only on a competitive market? To utilize the social links of their employees, are employers willing to pay a wage premium? We develop a model and provide results from a laboratory experiment to address these questions. We find that employers often hire via referrals, which in turn mitigates adverse selection and elevates wages. Importantly, employers anticipate the future value of hiring high-productivity employees—which consists of gaining access to valuable social links—and are thus willing to take the risk of offering wage premiums when hiring on the competitive market. We also find that employers' risk aversion and the dynamic nature of the hiring process can help account for the inefficiency remaining in the labor market.
