The Employment Recovery of Small and Large Employers
Article by: Marios Karabarbounis, Matthew Murphy and Nicholas Trachter

Policymakers, national pundits, and researchers often point to the importance of small
rms in job creation. Did small rms play a special role in the recovery of aggregate
employment during the pandemic? In this article, we use company-level employment data
from Ultimate Kronos Group (UKG), a workforce management software provider, to study
this question. Firms use the UKG software to manage the time of hourly workers. These
employees "punch-in" via the UKG timekeeping system when arriving at work (both in
person and virtually). The system computes the hours worked by each employee each
week, and this information is then used to pay the employee. As a result, the UKG data are
a good indicator of the number of shifts worked by hourly employees in the United States.
We thus interpret aggregate weekly punches in the UKG dataset as a measure of aggregate
U.S. employment.
The UKG data are available at a weekly frequency from January 2020 to September 2020
and provide weekly punches aggregated to the level of the parent rm or company. There
are 12,224 rms in the UKG dataset. The dataset provides an industry classi cation for
nearly three-quarters of the rms, spanning a wide range of industries: 34.1 percent of
rms are in services and distribution, 22.5 percent of rms are in manufacturing, 12.6
percent are in retail, 17.2 percent are in health care, and the rest are in the public sector. In
the analysis that follows, we focus on the number of weekly punches across time for rms
that were active (e.g., reporting a positive number of punches) during at least one week
during the months of January and February.
Aggregate Statistics
Figure 1 shows the time series of total weekly punches. Before the pandemic, there were
around 15.4 million punches logged in the UKG system each week. By the middle of April,
total weekly punches fell to 10.7 million, a 31 percent decrease. As states opened, the
number of weekly punches gradually increased to 14 million. This implies that, as of the last

/

week of September, aggregate hourly employment had recovered to around 9 percent
below the pre-pandemic level. Notice the temporary drops in employment during Memorial
Day week, the week around July 4, and the week around Labor Day.

Figure 2 shows the number of active rms each week, de ned as rms with at least one
week of positive punches in January and February (normalized by the average number of
active rms in January and February). The initial pandemic shock led to a massive drop in
active rms: 10 percent of rms active in March were inactive in late April. The number of
active rms increased between late April and late June but then began to decline again.
Overall, 8 percent of active rms in March were inactive by late September.

Small Versus Large Firms
We group rms according to their average number of weekly punches between January
2020 and February 2020. The rst group includes rms with fewer than 250 average weekly
punches, while the last group includes rms with more than 5,000 average weekly punches.
Table 1 presents some aggregate statistics across these groups. While smaller rms
account for a large fraction of rms, they account for a small fraction of aggregate weekly
punches: Nearly 60 percent of rms have 500 or fewer weekly punches, but they represent
only about 8 percent of the total punches.

Table 2 shows rm shutdowns by size. There is substantial variation: While only 4 percent
of the largest rms shut down operations for at least one week, 31.2 percent of the smallest
rms (fewer than 250 weekly punches) experienced at least a one-week shutdown. Further,
the incidence of a shutdown declines monotonically with rm size. Conditional on shutting
down the rm for at least a week, the incidence of long, maybe permanent, shutdowns is
similar across the rms of di erent sizes: Around half of rms that shut down did so for at
least eight weeks.

Despite being more likely to shut down, smaller rms experienced larger rebounds in terms
of total weekly punches than larger rms during the recovery that followed the initial
pandemic shock. Figure 3 plots the number of weekly punches across rms of di erent
sizes, where weekly punches for each group are normalized with respect to the group's
average of weekly punches during January and February. As mentioned, the gure shows
that while small rms experienced more shutdowns, they grew more quickly than larger
rms during the recovery.

Final Observations
We used rm-level data from UKG to analyze the path of the employment recovery for
small and large rms. Small rms were more likely to experience shutdowns than large
rms. However, small rms grew faster as the economy recovered.
A natural question is whether the exceptional employment recovery of small rms is
persistent. For example, small rms might expand their employment in response to
seasonal demand. If this is the case, we should expect the employment gains of small rms
to vanish soon, negatively a ecting unemployment in the next months.
Another aspect to consider is the role of government programs in aiding small rms during
the pandemic. Does the large employment growth of small rms re ect to some extent
their eligibility for loans through the Paycheck Protection Program?
While with our data we cannot make conclusive statements about whether the employment
growth of small rms re ects seasonal or persistent trends, or whether the success of small
rms is due to the recent government programs, we view our ndings as a meaningful
contribution to the discussion about the merits of size-dependent policies.
