Three academics claim to have a preliminary answer with the provenance of empirical science. William H. Dow, Arindrajit Dube and Carrie Hoverman Colla recently had an editorial in the New York Times arguing that San Francisco’s “near universal health care program” initiated early last year has not contributed to reduced employment despite the fact that “many businesses there had to raise their health spending substantially to meet the new requirements.”
How do they know the impact of this regulation on employment in San Francisco, when so many factors influence employment? They obviously can’t just look at whether employment went up or down after the law was passed. They need to answer the question: “But for the introduction of this regulation, what would employment have been?” The way they do this is identify a control group of other localities that did not introduce this change, and use this to proxy for what the change in employment in San Francisco would have been but for the introduction of this regulation. In the editorial they say “the early results are in”, and:
As of December 2008, there was no indication that San Francisco’s employment grew more slowly after the enactment of the employer-spending requirement than did employment in surrounding areas in San Mateo and Alameda counties. If anything, employment trends were slightly better in San Francisco.
There are at least two huge problems with concluding from this statement that the results so far in San Francisco tell us anything useful about the impact of such laws on employment. First, a period of just less than 12 months is almost certainly not enough time to observe the effects of the labor force impacts. Second, even if we accept this time period as relevant, the measurement method they describe is not nearly sufficient to identify significant changes in employment, positive or negative, caused by this law. Inadequate Time Period
Normally when the price of labor to a business goes up, the reaction of the business is some combination of (1) figuring out how to use less labor, and (2) just passing on the cost increase to consumers. If the business thinks all competitors face the same price increase, it tends to be a lot more of latter. Even when this is the case, the price of the whole category (whatever is sold by the business and all its competitors, whether this is an industry, geography or some other grouping) is now more expensive versus other categories of goods, so it tends to suffer over time as compared to what its sales and profits would have been had there been no labor price increase. This will tend to depress employment for companies in that category over time often in the form of new jobs that otherwise would have been created, but now are not. Further, this category-level price increase tends to invite the entry of new competitors who can find a way around the labor costs. An obvious example of this set of dynamics is that the ever-increasing economic costs of labor to the Detroit ecosystem created by synchronized union contracts seemed OK for a long time because “everybody” (i.e., GM, Ford and Chrysler) faced the same costs. Eventually, they became obviously unsustainable because of external competition. In sum, the employment effects of a structural increase in labor costs can take a long time to play through.
The authors argue, somewhat unpersuasively, that San Francisco, like Detroit decades ago, can raise labor costs with impunity:
Local service businesses can … raise prices without risking their competitive position, since their competitors will be required to take similar measures.
But of course, this assumes that these service businesses are not in competition, over time, with businesses outside of San Francisco. To some extent, they are.
They also make the argument that the improved health care should create an offsetting benefit. This isn’t like an oil price shock, which is just all bad, but a reallocation of resources that could grow the whole pie of wealth for San Francisco. The authors put this as:
Over the longer term, if more widespread coverage allows people to choose jobs based on their skills and not out of fear of losing health insurance from one specific employer, increased productivity will help pay for some of the costs of the mandate.
But think about the various dynamics involved. Labor costs rise in early 2008, and as a result prices are increased to some extent, and profit margins go down to some extent. Some restaurants lay people off, and other businesses are more reluctant to hire. As an example, last May the President of a local chain of hardware stores described avoiding hiring in order to remain below the 100-employee threshold for a more onerous tier of the program. Some people in San Francisco and the surrounding suburbs note prices are higher for dinner (and hammers, and groceries, and …) in the city, and start to buy marginally more goods and services in nearby towns, further pressuring margins and employment in San Francisco. Entrepreneurs, on the margin, locate businesses in Hayward or other towns just outside San Francisco, and as these businesses grow, the jobs that would have been created in San Francisco are now created in the suburbs. “Over the longer term” some career switches occur that otherwise would not, potentially raising labor productivity, growing the economy and increasing employment. How likely is all of this to play out in less than 12 months?
