privately held firms?Rebel A. Cole

The paper makes a significant contribution to the literature on executive pay at privately held firms…
…. which has been strongly limited by lack of data.
‘Published studies on compensation in privately held firms are essentially nonexistent because the data generally has not been accessible’.
Kee, et al (1999)

sampling
Analysis on privately held firms is based on data from 2 samples of firms conducted in 1993 and 2003 (SSBF).
The Surveys rely on a stratified random sampling design.
sampling
…Consistency between population and sample is provided for by sampling weights…
Some groups are over sampled (e.g., employee groups of size 20 and above), and the surveys contain weights to ensure that sample statistics represent the population.
(Herrants et al. 2009)
sampling ‘Stylised facts’ apparently do not control for the
structure of the sampling design (i.e. sampling weights are omitted)
..even if the risk of sampling error seems to be non negligible…
(the sampling fraction is around 0.002)
The total population of S-Corp and C-corp consists of about 2,400,000 firms in 1993 (2,800,000 firms in 2003)
and is represented by 4,356 firms in 1993 (4,240 firms in 2003)
The ‘final’ C&M sample consists of: 1,630 firms for 1993 (1,668 firms for 2003)(obtained by excluding firms who refused to response, firms whose the primary owner is not
the day-to day manager and public firms)
samplingSuggestion:
- Take into account sampling weights.
item nonresponse
Item nonresponse is significant in SSBF. ‘The 2003 Survey of Small Business
Finances (SSBF) screening interview had significant unit nonresponse and therefore some type of nonresponse adjustment was deemed necessary’
(Federal Reserve Board Finance and Discussion Series Paper, 2007).
item nonresponse
The authors say that some firms were excluded as they refused to divulge their amount of CEO compensation.
Suggestion: - The number of nonresponding firms
should be indicated and compared with sampling size
- Item nonresponse should be controlled for in case
item nonresponse
E.g. Are non responding firms more likely to
combine high compensations with low-performances than their peers?
(correlating characteristics of nonresponding firms to the Ceo pay question, with those of responding firms, that exhibit this pattern)
multivariate analysis
The authors find a much higher pay-size elasticity at private companies than for public firms…
…but also a drop of the pay-size elasticity for privately held firms from 1993 to 2003.
multivariate analysis
…which is supposed ‘to be driven by the growing familiarity with the use of the 0.30 benchmark among accountants of privately held firms’...
multivariate analysis
Do heterogeneous pay-size elasticities exist within privately held firms?
If differences exist but are not modelled,
a variation in the firms’ composition could translate in an apparent variation of the estimated (single coefficient for) pay-size elasticity.
multivariate analysis
‘The relatively uniformity of the elasticity of executive pay with respect to scale across firms, industries, countries and periods of time is puzzling
because the technology which sustains control and scale should vary across these disparate units of comparison’.
Rosen (1990)
multivariate analysis
Zhou (2000) models variations of the pay-size elasticity for firms having different size.
(he finds a higher elasticity for larger firms).
multivariate analysis
Kostiuk (1990)
- models firm heterogeneity by interacting ‘pay-size elasticity’ with ‘capital intensity’ (capital–labor ratio)
(pay-size elasticity is lower at firms having higher capital-labor ratios).
multivariate analysisSize distribution: Firm heterogeneity within
the period.
1st Quartile 4th Quartile
2003 0-4 54 - max
1993 0-6 62.5 - max
total employment (number of individuals)
(the survey may include firms having less than 500 employees)
multivariate analysisSize distribution: Firm heterogeneity across periods
In 2003 the median size of firms was lower than in 1993.
median ∆% (2003 vs 1993) 1993 2003
ASSETS ($) -22% 580,000 450,000
Total employment (numb.of ind)
-32% 22 15
SALES ($) -7% 1,500,000 1,400,000
multivariate analysis
Suggestion:
Interact pay-sale elasticity with
- Proxies for firms’ complexity
- Proxies for firms’ dimension
E.g. ‘Large’ (=1 for firms having sales larger than the sample median), Zhou (2000)
multivariate analysis
Legal type: heterogeneity across periods
C-corporations account for: - 60% of sampling firms in 1993- 30% of sampling firms in 2003
The relative importance of C-corporation (vs S-corporation) get reversed across periods.
multivariate analysis
Suggestion:
Interact pay-sale elasticity with ‘legal type’
return to educationReturn to education may be expected to vary
with ‘family ownership’.…Coeteris paribus, return to education for a
manager of a relatively large private firm inherited by the family may differ from that for a manager starting a new enterprise.
Suggestion: Interact the ‘Graduate’ and ‘College’ degree
dummies with- family ownership, - age of firms, - size of firms.
other comments
Different specifications between the 1993 and 2003 models prevent the comparison of results, ‘all being equal’:
- ‘firm’s D&B Credit Score’ is included only in the 2003 model
Suggestion: Presenting a model for 2003 by removing ‘firm’s
D&B Credit Score’ (which apparently correlates with RoA)
other comments
Regressions for pay-size elasticity, including the entire list of determinants, are available for sale as a measure of size.
In addition, ‘pay-assets’, ‘pay-employment’ elasticities are even scrutinized by C&M in the bivariate section…
…and by other authors.
Suggestion: Regressions for pay-size elasticity, including the entire list of controls, should be presented even for ‘pay-assets’ and ‘pay-employment’.
other comments
The interaction term:
Ownership*C-corporation
is discussed in the text…
(The relation Ceo pay vs ownership is stronger at C-corporations)
…. but apparently is not included in the set of regressions.
other commentsAs a corollary…
Interactions between pay-size elasticity and or size (or complexity) may signal the extent of the ‘measurement error’…
The Survey’s question on executive pay is:
‘Which is the total amount of officers’ compensation? ‘,
(not CEO pay)
other comments
Exercises conducted by C&M seem to indicate that the measurement error is low.
The measurement error is expected to increase with firms’ size.
If interactions between pay-size elasticity and size, after controlling for the other determinants, prove to be insignificant…
…the measurement error would be implicitly negligible.
conclusions
The paper is definitely original, full of information, and very enjoyable to read.
The empirical analysis is comprehensive and shed light on important up till now obscure issues.
conclusionsCompositions effects may have an impact on the results.
Among privately held firms, heterogeneity in size and complexity should be properly dealt with.
Causal effects, controlling for endogeneity, have still to be scrutinized.
Thanks for your attention.
