Unions and hospitals: some unresolved issues.

Area of Science:

• Health Economics
• Labor Economics
• Industrial Relations

Background:

• Previous studies using Ordinary Least Squares (OLS) indicate a moderate wage increase for hospital workers due to unionization.
• The healthcare sector's wage structure is influenced by various factors, including union presence and reimbursement policies.

Purpose of the Study:

• To investigate the precise impact of labor unions on the wages of hospital workers, accounting for potential selection bias.
• To analyze the indirect effects of unionization within hospitals and local labor markets.
• To examine the influence of prospective reimbursement programs and market structures (monopsony) on hospital wages.

Main Methods:

• Ordinary Least Squares (OLS) regression analysis.
• Correction for selectivity bias in hospital unionization status.
• Empirical testing for the presence of monopsony in hospital wage-setting.

Main Results:

• OLS estimates show unions increase registered nurses' (RNs) wages by 5% and other hospital workers' by 8-10%.
• After adjusting for selectivity bias, direct union effects are estimated at 20% for RNs and over 30% for other hospital workers.
• Indirect union effects range up to 5% from other hospital occupations and 10% from local unionized hospitals. Prospective reimbursement negatively impacts non-unionized workers' wages.
• Monopsony power was not found to be a significant factor in hospital wage determination.

Conclusions:

• Unionization has a substantial direct and indirect impact on hospital worker wages, particularly after accounting for selection bias.
• While unions increase labor costs, their contribution to overall hospital cost inflation appears to be minor.
• Policy considerations regarding healthcare wages should acknowledge the significant role of labor unions.
