Competition, information, and quality: Evidence from nursing homes

Area of Science:

• Health Economics
• Market Competition
• Healthcare Quality

Background:

• Economic theory posits competition and information influence product quality.
• Empirical evidence on the interaction between competition and information transparency affecting quality is limited.
• Nursing home quality is a critical concern for elderly care and public health.

Purpose of the Study:

• To estimate the impact of competition on nursing home quality.
• To examine how increased information transparency modifies the competition-quality relationship.
• To inform policy on market structure and public quality reporting.

Main Methods:

• Utilized exogenous variation in nursing home geographical proximity to consumers to identify competition effects.
• Assessed changes in information transparency using the 2009 launch of the Five-Star Quality Rating System.
• Employed econometric analysis to quantify the interaction between competition and information on quality outcomes.

Main Results:

• Competition among nursing homes demonstrated a generally limited effect on overall quality.
• Increased information transparency, via the Five-Star Rating System, significantly amplified the positive impact of competition on quality.
• The findings indicate a synergistic relationship between market competition and public quality information.

Conclusions:

• Policy interventions regulating public quality reporting and market structure are complementary.
• Joint consideration of these policies is essential for effectively improving nursing home quality.
• Enhanced information transparency can unlock the potential of market competition to drive quality improvements in healthcare.
