based on work joint with Andrea Prat (CBS) and Raffaella Sadun (HBS)
Some firms systematically perform better than others

The CEO Factor is a popular explanation
• Can differences in firm performance explained by the leadership style of the CEO?L t f d t• Lots of anecdotes

Yet little is known about what CEOs do
how do CEOs use their time?how do CEOs use their time?is it correlated with firm performance?
if so, why do different CEOs do different things?
We ask them
• Develop a new survey methodology to collect data on time use of CEOs
• Time use:– what they do– who with– how far in advance they plan..y p
• provide systematic quantitative evidence on what CEO do, whether it correlates with firm performance pand whether (and why) it differs across firms
• builds on case‐study “shadowing” approach
Research Overview
• We developed a methodology to acquire a wealth of p gy qdata on time use: what CEOs do.
• By analyzing time use, we identify different approaches to management.pp g
• We study how these are correlated with productivity, and with firms characteristics
• Tool for CEOs, researchers, policymakers, MBA students

Our Methodology
Our rich data set allows us to go beyond organizational charts to observe how CEOs use their time.

different activities…
Why India?• (Obviously) very large and very poor• Three key features of Indian manufacturing:
– strong growth in early 90sg g y– large dispersion in productivity, long thick tail of low productivity firmsproductivity firms
– large dispersion in managerial practices, long thick tail of poorly managed firmsof poorly managed firms
• Differences in CEOs’ management style might provide i i ht th b d h t it finew insights on the observed heterogeneity across firms.

Sample selection• Sampling frame is: 8,000 listed manufacturing firms with accounting data on ORBIS
p
with accounting data on ORBIS• Restricted to:
– firms active since 2006– firms active since 2006– largest states + $2 million in sales
• Out of 3 500 firms we could find contact details for• Out of 3,500 firms we could find contact details for 1,429 CEOs. Of th 26% d t ti i t• Of these, 26% agreed to participate
• Sample firms have 1.8% lower sales but no significant selection on performance
Our Samplep
• Firm characteristics– 1220 employees avg. (median=400)– 15 states (Maharashtra 36%, Gujarat 15%)– 70% family CEO
• CEO characteristics– 50 years old– 13 years in post– 41% with MBA– all men
Collecting time use datag
f l d b d i• Team of 15 analysts and 3 managers based in Mumbai‐May to July 2011
• Cold call CEOs to get their approval (offer personalized time use analysis in exchange)p y g )
• Call each CEO’s PA every day for a week• Collect detailed information on all activities• Collect detailed information on all activities longer than 15 minutes
• Final check with the CEO at the end of the week
Why PA?
“F th f t I’ b
y
“For more than fourteen years, I’ve been human answering machine, auto dialer, word
filt i t d f t h kprocessor, filtering system, and fact checker; been a sounding board, schlepper, buddy, and bearer of good and bad tidings; served as abearer of good and bad tidings; served as a scold, diplomat, repairperson, cheerleader and naysayer; and performed dozens of other rolesnaysayer; and performed dozens of other roles under the title of ‘assistant’.”
Roxanne Sadowski, Jack Welch’s PA
Collecting time use datag
mondaynight
• ask about activities done on mondayand schedule for tuesdaynight y
tuesdaynight
• ask about activities done on tuesday and schedule for wednesday
d dwednesdaynight • ….
We first ask for a list of all the activities undertaken
We then ask a LOT of detail for each activity
Limitations
• we do not measure activities out of business hours that are not on the CEOs diaries
• we do not measure activities shorter than 15 minutesminutes
• this implies we understate hours worked• but can still meet our goal of measuring CEOs management stylemanagement style
Time use or noise?• a week might not be enough to capture typical CEO behavior e g due to high frequency shocksCEO behavior, e.g. due to high frequency shocks
• three reassuring pieces of evidence:– time use is systematically linked to specific firm characteristics (e.g., firm size) ( g , )
– large correlation across dayssubstantial heterogeneity in time use even if we– substantial heterogeneity in time use even if we restrict the sample to the 60% of CEOs who score the survey week as highly representativesurvey week as highly representative
So what?
• Do CEOs differ systematically in style?• Is this correlated with productivity?Is this correlated with productivity?• Is it shaped by their preferences or by the
i h i ?environment they operate in?
Looking for “style”g y
i l k l l i d• We use a simple k‐cluster analysis to reduce multi‐dimensionality of time data to a simpler classification
• Assign CEOs into groups so that CEOs in the g g psame cluster are more similar to each other than to those in other clusters
• Start from minimum interesting number of groups: k=2groups: k=2
• Data reveals two very different CEO styles

Interpretation • Reverse causality bias a priori ambiguous
p
– Positive if productivity shock increases returns to CEO labor supply, reduces need to firefight, etc
– Negative if productivity shock generates free cash flows, allows for substitution with labor,
• Omitted variablesE g matching firms and CEO types– E.g. matching firms and CEO types
– Placebo test shows no correlation between hours, l d f i b f CEO i i ffistyle and performance in years before CEO is in office
Why do CEOs differ?y
• If effort and style green are associated to higher performance, why are there differences across CEOs?
1. optimal response to external constraints:– Weak rule of law creates incentive for hands‐on approach – Bad infrastructures might constrain ability to plan
2. differences in production functions2. differences in production functions3. differences in preferences/incentives/accountability

• Suppose that the cost of going to work is higher when monsoon rains hitg
• The d‐i‐d (ownership/weather) identifies differences in motivation/ability fromdifferences in motivation/ability from differences in technology
• … but cannot separate motivation and ability
The onset of the Monsoon in India
• Monsoons officially started on May 29th 2011 and lasted
til S t b 15thuntil September 15th
• Onset varies across states (Tamil Nadu hit on May 29th(Tamil Nadu hit on May 29th, Rajasthan on July 1st)
• 70% of CEOs data collected• 70% of CEOs data collected after Monsoon hit the area
• Activity specific zip codeActivity specific zip code used to match CEO use of time with daily rainfall data collected in closest weather station
Rainfall increases significantly during the Monsoon
Weeks before/after onset of the Monsoon in the StateNotes: Rainfall data from 49 stations matched to the CEO sample (793 unique station-day observations).Logarithmic change relative to station specific rainfall averages in May 2011.
Rainfall intensity also varies within a week
