Course Objectives
This course is built on 10 years of research by LSE, McKinsey &
Stanford, with recent extensions with Accenture, Harvard Business
School, the World Bank and the European Bank for
Reconstruction & Development
This course aims to provide to do three things:
• Provide a “management 101” overview of basic practices
• Explain how management practices vary around the world
(and why)
• Introduce you to some management research techniques

Course Organization
Nick Bloom (Stanford Economics) and John Van Reenen
(Stanford GSB/LSE) will co-teach the course.
There will be no take home work or exams
Passing the class for credit simply requires:
1. Class attendance
2. Class participation
a. Individual presentations
b. Questions, experiences and response
All slides will be put up within 24 hours of class on website
http://www.stanford.edu/~nbloom/

Class Presentations
From Lecture 2 (Jan 12th) onwards there will be a presentation by
someone from the class. There will be 8 presentations
We will be asking for volunteers half-way through this lecture!
Nick Bloom and John Van Reenen, Management Practices, 2010
5
Class Presentations Structure (1/2)
Present 6 slides on a firm you know, covering:
1) What the firm does: e.g. products, size, location, competitors
2) Your relationship to the firm (an employee, family firm etc)
3)
4)
5)
6)
Talent management practices: score and some examples
Targets management practices: score and some examples
Performance management practices: score and some examples
Your three tips to improve management in the firm
Suggested guides:
(1) All slides in 24 point font or greater
(2) At least one picture per presentation
(3) Be creative – make it interesting and engaging
Nick Bloom and John Van Reenen, Management Practices, 2010

Class Presentations Structure (2/2)
• The presentations should last about 10 minutes without
questions, so about 20 minutes given we expect discussion.
• The preparation of the slides should take about an hour, certainly
no more than 2 hours.
• In advance of presenting in class you are advised to have a
practice run through with either of us (e-mail to set up time to do
this). We can give you some feedback and suggestions.
• This is supposed to be fun, helpful and a way to get excellent
class involvement grades.

Course Timing
Classes run from 8:15 to 9:45, Tuesday and Thursday
John and Nick will also be around for as long as necessary after
class to answer questions, and are happy to meet up at other
times as well (again, just e-mail us).
INTRODUCTIONS & QUESTIONS

Introduction
Why care about management and productivity?
Nick Bloom and John Van Reenen, Management Practices, 2010
9
Productivity
• GDP per capita (Income per person) basic indicator of
economic wellbeing
• GDP per capita increases by growth of inputs (e.g. more
capital or labor) or higher Total Factor Productivity (TFP)
Nick Bloom and John Van Reenen, Management Practices, 2010
10
Some basic Productivity Concepts
Output = Inputs + Total Factor Productivity (TFP)
e.g. Labor, capital, materials
Labor Productivity=
Output per employee = Inputs per employee + TFP
Nick Bloom and John Van Reenen, Management Practices, 2010
11
Productivity “Facts”
• Macro: Productivity varies hugely across nations and
over time
– Robert Solow: TFP growth at least as important as
growth of inputs in explaining economic growth
– Cross country GDP/capita differences largely due to
TFP differences
– Productivity slowdown 1973-1995 and “miracle” post
1995
• Micro: Productivity varies hugely across firms
Nick Bloom and John Van Reenen, Management Practices, 2010

In long-run most countries have enjoyed catch up
Growth with the GDP/head leader (US) but not all

13
Large Income & TFP Differences between countries
Source: Jones and Romer (2009). US=1
Nick Bloom and John Van Reenen, Management Practices, 2010
14
Why it matters for policy
• Increasing TFP means that the economic pie is bigger so
more room for
– Consumption
– Tax cuts
– Increases in public goods (e.g. Environmental quality)
• Harder to achieve if productivity stagnant
• But what can be done to increase productivity?
Nick Bloom and John Van Reenen, Management Practices, 2010
15
Factors increasing productivity
• Proximate factors:
– Hard technology (e.g. R&D)
– Skills (e.g. Expansion of college education)
– Management (a technology & a skill?).
• Some deeper factors “driving” the above
– Competition
– Globalization
– Regulations/policies
– Culture
Nick Bloom and John Van Reenen, Management Practices, 2010
16
Productivity Differences across firms within
countries is huge
• Census data on population of plants
– US: plant at the 90th percentile produced 4x higher labor
productivity as plant at the 10th percentile (Syverson, 2004)
• Controlling for other inputs
– TFP difference 1.9 in US
• Not just mismeasured prices: in detailed industries (e.g.
Boxes, bread, carbon black, block ice, concrete,
plywood, etc.) productivity differences get bigger (Foster
et al, 2008)!
• Not just temporary shocks
• Could account for large part of cross country differences
Nick Bloom and John Van Reenen, Management Practices, 2010
17
Distribution of plant TFP differences: Higher average US
productivity due to fewer less productive plants
Source: Hsieh and Klenow (2008); US mean=1
Nick Bloom and John Van Reenen, Management Practices, 2010
Big TFP dispersion among US ready mix concrete plants: More
Competition means higher productivity (cut off lower tail)
Low competition
High competition

Nick Bloom and John Van Reenen, Management Practices, 2010
19
How Total Factor Productivity increases
• Within Firms (Traditional view)
– The same firms become more productive (e.g. new
technology spreads quickly to all firms, like Internet)
• Between Firms (Schumpeterian view)
– Low TFP firms exit and resources are reallocated to
high TFP firms
• High TFP firms expand (e.g. more jobs), low TFP
firms contract (e.g. less jobs)
• Exit/entry
Nick Bloom and John Van Reenen, Management Practices, 2010

Some Empirical Evidence on reallocation
• Need large-scale database of many firms/plants observed
over time (panels)
• Reallocation appears to be an important factor:
– In aggregate US productivity growth: c.50% of aggregate TFP
growth in a 5 year period in typical industry due to reallocation
(Bailey et al, 1992)
– Following trade liberalizations: about half of productivity gains due
to shrinking/exit of less productive plants (e.g. Pavcnik, 2002)
– For certain sectors: In retail trade, just about all of labor
productivity growth is due to exit/entry of stores (Foster et al,
2006)
• Caveats
– Reallocation is not immediate (e.g. trade dislocation)
– Some shocks can destroy valuable “specific capital”
Nick Bloom and John Van Reenen, Management Practices, 2010
24
Management
• Case studies management in similar industries and
positions respond differently
– Toyota and General Motors
– Goldman Sachs and Lehman Brothers
• Obviously management matters but
– how to generalize?
– how much does it matter?
– what causes the differences?

Examples of management as a technology?
Waves of management technologies have arisen over time
• American System of Manufacturing (1850s)
• Taylor’s Scientific management (1900s)
• Mass production (1920s)
• Alfred Sloan’s M-form firm (1930s)
• Demming’s quality movements (1950s)
• Toyota production system (1970s)
Nick Bloom and John Van Reenen, Management Practices, 2010
27
What we need
• A way to quantitatively benchmark management
practices
– At the firm-level
– Across countries and sectors
– That can be matched with firm performance data
Nick Bloom and John Van Reenen, Management Practices, 2010
28
Conclusion
• Looked at why productivity was important for the
wealth of nations
• Discussed factors that might influence
productivity, in particular considered management
