Competition and screening with motivated health professionals.

Two hospitals compete for the exclusive services of health professionals, who are privately informed about their ability and motivation. Hospitals differ in their ownership structure and in the mission they pursue. The non-profit hospital sacrifices some profits to follow its mission but becomes attractive for motivated workers. In equilibrium, when both hospitals are active, the sorting of workers to hospitals is efficient and ability-neutral. Allocative distortions are decreasing in the degree of competition and disappear when hospitals are similar. The non-profit hospital tends to provide a higher amount of care and offer lower salaries than the for-profit one.

Bidimensional Screening with Intrinsically Motivated Workers

We study the screening problem of a firm that needs to hire a worker to produce output and that observes neither the productive ability nor the intrinsic motivation of the job applicant. We completely characterize the set of optimal contracts according to whether motivation or ability is the main determinant of the worker’s performance. We show that it is always in the firm’s interest to hire all types of worker and to offer different contracts to different types of employees. Interestingly, when motivation is very high, incentives force the firm to pay higher informational rents, to increase effort distorsions for motivated workers, and to offer a strictly positive wage to workers enjoying a positive utility from effort provision, who thus become paid volunteers. These results suggest that, from the principal’s viewpoint, very high motivation might not be a desirable worker’s characteristic.

Competition and Screening with Skilled and Motivated Workers

We study optimal contracts offered by two firms competing for the exclusive services of one worker, who is privately informed about her ability and her motivation. Firms differ both in their production technology and in the mission they pursue and a motivated worker is keen to be hired by the missionoriented firm. We find that the matching of worker types to firms is always Pareto-efficient. When the difference in firms’ technology is high, only the most efficient firm is active. When the difference is not very high, then agent types sort themselves by motivation: the mission-oriented firm hires motivated types and the profit-oriented firm employs non-motivated ones, independently of ability. Effort provision is higher when the worker is hired by the mission-oriented firm, but a compensating wage differential might exist: the motivated worker is paid less by the mission-oriented firm. Such an earnings penalty is driven entirely by motivation, is increasing in ability and is associated to low power of incentives.

The Lemons Problem in a Labor Market with Intrinsic Motivation: When Higher Salaries Pay Worse Workers

We study the Lemons Problem when workers have private information on both their skills and their intrinsic motivation. When workers are motivated, ine¢ ciencies due to adverse selection are mitigated and a change in salaries may have unexpected consequences. With a su¢ ciently strong and positive association between motivation and productivity, a wage increase may attract less motivated and also less productive workers. When the association is positive but small, it instead may attract more productive and also more motivated workers. Our theoretical analysis reconciles contrasting empirical evidence on vocational sectors such as for public servants, teachers, health professionals and politicians. Our results also inform the current policy debate on whether it is possible to improve the overall quality of workers by changing their salary.

Competition Between For-Profit and Non-Profit Firms: Incentives, Workers’ Self-Selection, and Wage Differentials

We study optimal non-linear contracts offered by two firms competing for the exclusive services of workers, who are privately informed about their ability and motivation. Firms differ in their organizational form, and motivated workers are keen to be hired by the non-profit firm because they adhere to its mission. If the for-profit firm has a competitive advantage over the non-profit firm, the latter attracts fewer high-ability workers with respect to the former. Moreover, workers exert more effort at the for-profit than at the non-profit firm despite the latter distorts effort levels upwards. Finally, a wage penalty emerges for non-profit workers which is partly due to compensating effects (labor donations by motivated workers) and partly due to the negative selection of ability into the non-profit firm. The opposite results hold when it is the non-profit firm that has a competitive advantage.
