Baumol's Disease Explains Voter Dissatisfaction With Public Services

Voter dissatisfaction with public services can be understood through the lens of "Baumol's disease," an economic theory first articulated by William Baumol and William Bowen in their 1966 book "Performing Arts: The Economic Dilemma." This theory explains why productivity in certain service sectors, particularly those with a high human-labor component, struggles to keep pace with technological advancements in other industries. Classical music performances serve as a prime example: the time it takes to perform a symphony has not changed significantly over centuries, despite advancements in technology. This inherent lack of productivity growth means that the cost of providing these services, relative to other goods and services, tends to rise over time. As wages in other sectors increase due to productivity gains, wages in sectors like classical music, or public services, must also rise to attract and retain talent, even if the output per worker remains constant. This leads to a situation where the cost of delivering these services escalates, even if the quality or quantity of the service does not improve, or even declines.

When applied to public services such as education, healthcare, or public transportation, Baumol's disease suggests that the cost of delivering these essential services will naturally increase at a faster rate than inflation in the broader economy. This is because these services, like live performances, rely heavily on human interaction and labor, making them less susceptible to labor-saving technological innovations that drive down costs in manufacturing or information technology. For instance, a teacher's ability to educate more students simultaneously without a decline in quality is limited, unlike a software engineer who can leverage tools to produce more code in the same amount of time. Consequently, as the economy-wide wage level rises, the cost of employing teachers, nurses, or transit operators also rises, even if their individual productivity hasn't increased. This persistent cost pressure means that governments must allocate a larger portion of their budgets to maintain the same level of public services, or face a decline in the quality or availability of those services.

This economic reality directly impacts taxpayers and voters. When citizens observe that their tax contributions are increasing, yet the quality of public services they receive appears to be stagnant or deteriorating, they experience a sense of frustration and dissatisfaction. They may feel they are paying more for less, a sentiment that aligns with the core prediction of Baumol's disease: the relative cost of services with low productivity growth will inevitably rise. This can lead to a perception that public funds are being mismanaged or that the government is inefficient, fueling political discontent. The challenge for policymakers is to acknowledge and address this inherent economic dynamic. Solutions might involve finding innovative ways to increase productivity in public services, such as through technology adoption where appropriate, or by managing public expectations about the rate at which service quality can improve relative to cost. Without understanding Baumol's disease, the disconnect between rising tax burdens and perceived service quality remains a perplexing and politically charged issue for many citizens.
