Disclosing Labor Demand: Evidence from Online Job Postings

Summary

The research paper "Disclosing Labor Demand: Evidence from Online Job Postings" by Gurpal S. Sran investigates the strategic choices firms make when disclosing information in online job advertisements. The core of the study revolves around a fundamental trade-off: detailed job postings are beneficial for attracting and informing optimal job applicants (referred to as the "labor market channel"), but they simultaneously risk revealing sensitive information to competitors in both labor and product markets (termed the "proprietary costs channel"). To understand this trade-off, Sran first provides evidence supporting the existence of a proprietary costs channel. The study observes that, even when controlling for specific labor demand characteristics, private firms and those that redact information tend to write shorter job postings, indicating less contextual specificity. Furthermore, job postings are more frequently anonymous in industries characterized by high levels of secrecy. These findings suggest that firms actively limit the information they disclose to protect proprietary interests. The methodology then exploits a quasi-natural experiment: the implementation of federal trade secrecy protections. This event serves as an exogenous shock that simultaneously influences firms' incentives for innovation and their desire for opacity. Following the implementation of these protections, the study reveals several key findings. Firms begin to demand higher skill levels for innovative jobs, which is consistent with the idea that stronger intellectual property protections encourage innovation. However, there is a concurrent decrease in contextual specificity within job postings, aligning with the proprietary costs channel, as firms maximize protection by remaining opaque about their innovations. This reduction in specificity is notably attenuated in tight labor markets, suggesting that the competitive pressure for talent forces firms to disclose more, even when proprietary costs are a concern. This highlights the dynamic balance between the need to attract talent and the desire to safeguard sensitive information. The data used in this study are available from sources identified in the manuscript.
