"Do increases in the minimum wage only manifest themselves in reduced
employment? Or are there other not-so-visible, but also not-so-trivial,
effects that should be part of the policy discussion? As I will argue
with a short anecdote, the consequences of government interfering with
private labor contracts can arise in some surprising places.
A Caffeinated Conundrum
There is a small coffee bodega in one of the university buildings
where I frequently teach classes. I regularly stopped and purchased a
16-ounce drip to fuel me through afternoon seminars.
One day something mysterious happened. When I pulled out a few dollar
bills to pay for my beverage, the barista quickly said, “I’m sorry but
we no longer take cash.”
“Why?” I asked.
“We want to serve all of our customers better, so we only take credit and debit cards,” the attendant cheerily replied.
I quickly fired back. “But I am a customer, and I never use a credit
or debit card for anything below twenty dollars! This is not serving me
better!” (As this was nine years ago, I will let readers ponder whether I
still prefer cash.)
The poor employee, visibly flummoxed by my answer, reiterated that he
was not allowed to accept cash. In fact, he informed me, to my dismay,
that all campus food service locations now refuse cash. (I will further
let readers speculate as to whether I paid for the already-poured
beverage with a card or left the drink at the counter and left.)
Herein lies a mystery. Why would our university’s food service
outlets stop accepting cash? By making it hard for someone like me to
pay, wouldn’t they risk losing business? I asked this of my seminar
students that day, and several reasonable answers were given.
The first answer was that “nobody uses cash anymore so Professor Gill
must be a weirdo and who would want a weirdo as a customer.” While it
is true that fewer and fewer people pay with, let alone carry, cash
these days (particularly college age students), I do know of enough old
faculty like me that prefer greenbacks as the primary means of exchange.
The bodega certainly lost my business going forward and probably a few
other gray-haired faculty. While we are an old-fashioned minority,
cutting off an opportunity for exchange seems like a poor business
decision.
The second answer advanced was that going cashless makes sense if you
want to prevent crime. Cash is easy to steal and is fungible; credit
card receipts are not. Eliminate cash, and you eliminate a major
incentive for robberies. This is not such a bad hypothesis, considering
it has been the rationale
for several Seattle-area businesses as crime has risen dramatically in
recent years. Nevertheless, our campus in 2016 was not a hotbed of theft
and most of the food service outlets make awkward robbery targets based
on where they are located. Admittedly, we were starting to see an
increase in homelessness on campus, so going cashless may have been a
means of trying to discourage vagrants from using our cafeterias.
It’s the Minimum Wage, Stupid
Not satisfied with any of my students’ answers, I started my own
investigation into the situation by talking with different cashiers and
managers around campus. Most were not actually given any rationale for
the change by their bosses; they were told not to accept cash and that
is what they did. Nonetheless, one intriguing answer did emerge after a
few conversations – it was a way to cut labor costs.
In 2014, the City Council of Seattle passed an ordinance
that incrementally increased the minimum wage from $9.47 to $15 per
hour over a two year period starting in April 2015. Do the math; that is
a 58 percent increase in the base wage in just twenty-four short
months. My university, being the progressive employer it is, typically
offers a wage higher than the legislated minimum to benefit work-study
students struggling to pay off ever-increasing tuition — a virtuous
cycle if there ever was one!
But why should an increase in the minimum wage affect whether or not coffee shops accept cash?
Here’s the rub. If retailers accept dollar bills and coins, employees
must reconcile (or “cash out”) their till at the end of shift, making
sure that the money they have on hand matches the receipts sold for the
day. This is done for bookkeeping purposes and to monitor whether
cashiers are pilfering.
But “cashing out” requires time. Not a major amount of time, mind
you, but enough so that an employee might spend an additional fifteen
minutes on this task. Even if the task only takes a few minutes, the
employer is usually required to pay a quarter hour’s wage. At the new
minimum wage of $15/hour, that equals an additional $3.75. Calculated as
a change from the early $9.47 minimum wage, that is roughly an
additional $1.50 per hour that must be paid merely to have an employee
count cash.
While such an increase in wage cost seems trivial, remember that the
employer was also paying an additional $4 per hour throughout the
employee’s entire shift (plus the increase amount paid into FICA at a
higher base wage). Moreover, we’re not just talking about one employee.
For a campus-wide operation with dozens of outlets, you are paying this
added expense across a large number of employees working a large number
of shifts across multiple days, weeks, and months. Those costs add up
quickly and are often reflected in higher prices that potentially chase
away customers.
(The problem is exacerbated for college food service because students
have shorter shifts under work-study requirements. Instead of paying
one employee fifteen more minutes to cash out after an eight-hour shift,
you end up paying two employees an additional 15 minutes each to cash
out after their four-hour shifts, 30 minutes. Student workers on short
shifts are more expensive than non-students working a full eight hours.
It isn’t surprising that my university led the way among local eateries
and coffee shops in going cashless.)
If you want to shave labor costs to minimize upward pressure on
product prices, simply eliminate the $3.75/hour (or more) you pay
employees to reconcile their till. In other words, if you eliminate
cash, you eliminate the expense associated with cashing out. When all
payments are conducted electronically, employees need only click a
single button at the end of the shift and all receipts are tallied
automatically. Voila — immediate cost savings!
And so, the mystery was solved. It was a rapid increase in the
minimum wage that took away my ability to buy coffee with cash. Customer
inconvenience is an economic cost, and it is a cost that is often
ignored by econometric studies considering only employment effects of
minimum wage legislation.
But Wait…There’s More (of Less Service)!
Undoubtedly, some of you may be rolling your eyes at my analysis.
“Prof. Gill, is the minor inconvenience of using a credit card such a
major burden relative to the economic gains and social justice that
results from paying workers better?” To that, I answer emphatically,
“YES!” It matters to me, and I have decreased my on-campus purchase of
coffee dramatically since then, preferring to carry a thermos from home
now. Customer inconvenience is a real cost, and there is more to it than
just having to reach for my MasterCard.
In 2017, a task force of University of Washington (UW) researchers published a report
(with updates) evaluating the costs and benefits of Seattle’s rather
dramatic minimum wage policy. Interestingly, the team went beyond
looking merely at employment effects but also conducted in-depth
interviews with several restaurateurs in the city about the adjustments
they were making to the policy. Increasing menu prices was one of the
primary methods of dealing with the increased labor costs, but
restaurateurs and other service-oriented businesses were reluctant to do
that given the fear of losing customers in a highly competitive
market.
One of the surprising things the UW research team found was that
several lower-mid-tier restaurants were eliminating direct table
service. Instead of wait staff taking orders at the table, bringing the
food, and bussing the tables, customers would order at a counter, pick
up their own food, and be encouraged to deposit their dishes at a
separate bussing station. In essence, some table service restaurants
began to look more like McDonald’s.
Again, this may seem trivial in the grand scheme of things, but
losing the experience of table service and the interaction of an
attentive server does diminish the overall dining experience. Granted,
this did not happen at four-star, white tablecloth establishments that
have clientele who can absorb higher menu prices. The restaurants
affected tended to serve lower-income individuals who suddenly were
presented with a lower quality of service. Considering that proponents
of higher minimum wages are usually advocates for the poor, it is odd to
forget that the poor are not just workers, but customers as well. And
why shouldn’t lower income individuals enjoy the benefits of table
service at restaurants?
Another key finding of the UW report was that restaurants responded
to the increased wage by reducing staff hours. This is noteworthy as
previous studies typically focused attention on whether increased
minimum wage rates would create greater unemployment, including the
famous Card and Krueger “natural experiment” study that showed little effect on layoffs. But such studies viewed labor as a binary variable – you were either working or not.
In reality, labor is a continuous variable; employees can work 40
hours per week or just 30 hours. In Seattle, employers reacted to higher
labor costs by reducing hours of their staff rather than laying them
off. Finding and training new employees is expensive. Rather than laying
off current workers, it made sense to cut their hours and hope there
wouldn’t be any corresponding loss in productivity. Notably, the UW
study found that while the average hourly pay for service employees did
increase due to minimum wage increases, the reduced hours worked meant
that there was little gain (and even a small loss) in overall monthly
pay.
But again, it is not just the labor effects that we must pay
attention to when evaluating the effects of minimum wage increases. With
employers cutting back on hours, customer service takes a hit.
Consider food service once again. While there is some degree of
predictability with restaurant and bodega traffic, surprises always
occur. A “typical” slow Wednesday might be hit with an unexpected rush
of traffic. As restaurants are evaluated not only on food quality but
service as well, not having enough staff on hand to handle that rush
will likely result in slower service. For that reason, restaurants favor
having additional wait staff and kitchen help on hand just in case.
With labor costs rising, though, such a strategy becomes untenable in a
sector with slim margins. The other option being pursued by several fast
food outlets is to simply replace human workers with automated kiosks.
While this may work for a quick meal at Burger King, the prospect of
this alternative at casual sit-down dining establishments seems horrid.
Owners may also shorten the hours of business, leaving early bird or
late-night customers with fewer options (just like my cashless coffee
bodega). All of this is likely to create disgruntled customers who
spread their bad experiences online or via word of mouth. While
anecdotal, many of my acquaintances and I have noted that the quality of
restaurant service in Seattle has declined significantly over the past
decade and many of us have scaled back our dining habits. And we’re not
alone. Fewer people have been eating out and restaurants have been closing
in surprisingly high numbers. The impact of a minimum wage increase
need not be immediately felt; through the slow decline in service and
convenience, an entire sector withering away.
The Bottom Line Isn’t Always about the Money
Policy debates regarding the minimum wage typically focus on labor
and whether providing a “living wage” improves the lot of workers or
leads to increased unemployment. But that is only one side of the coin.
Consumers are also affected by minimum wage policy, be it in terms of
higher prices or, as we have seen, declining service and options. These
interests must be considered when formulating policy. Government
mandates often have unintended consequences, and not in ways that are
easily measured.
We all benefit from a vibrant service sector; making it difficult for
business to offer quality service and plentiful options for a diverse
customer base will only harm the economy writ large."
