1 MEASURING AND EXPLAINING MANAGEMENT PRACTICES ACROSS FIRMS AND COUNTRIES October 2007 Nick Bloom Stanford & NBER John Van Reenen LSE & NBER

2 MOTIVATION Large persistent productivity spread across firms and countries: people typically claim this is due to differences in “management” But what is the role of management? And why does it vary so much across firms and countries?

3 SUMMARY OF THE PAPER (1 of 3) (1) Measuring Management Develop a survey tool to “measure” management practices New data on 732 firms in US,UK, France & Germany. Management data: Appears consistently measured within firms Correlated with productivity, profits, Tobin’s Q, growth & survival Robust to measurement error and bias

4 SUMMARY OF THE PAPER (2 of 3) (2) Explaining Management Observe big spread in management practices (Fig. 2 over) Wide cross firm spread (like profits & productivity) Significant differences across countries US 1 st, Germany 2 nd, France 3 rd and UK 4 th Demonstrate that two factors appear significant: Production market competition – positive effect Family managed firms – negative effect Family firm ownership but not management is fine Family ownership and management problematic, particularly under primo geniture CEO succession

5 FIRM LEVEL AVERAGE MANAGEMENT SCORES Francen=137n=157 n=290n=154UKUS Germany

6 SUMMARY OF THE PAPER (3 of 3) (3) Quantifying this Effect Competition and family-management important, explains about 50% of firm-level management tail; and between 1/3 to 2/3 of US-Europe management gap: Europe has lower levels of competition UK & France also many more primo geniture family firms due to Norman legal origin & tradition

8 Why Should Management Practices Vary? Two models - not mutually exclusive “Optimal choice of management practices” Another factor of production (like advertising) No “better” or “worse” style of management – depends on firm’s circumstances Exogenous managerial inefficiency (Mundlak, 1961; Lucas 1978) Part of total-factor productivity Strictly “better” or “worse” styles of management Empirically we find some support for both

10 SOME RELATED LITERATURE - EXAMPLES Management, organisation & performance HRM / Management practices: Ichinowski, Shaw, and Prenushi (1997), Ichinowski and Shaw (1995), Black and Lynch (2001), and Lazear (2000); Cappelli and Neumark (2001), Bartel, Ichniowski and Shaw (2004), Organisational practices: Bresnahan, Brynjolfsson and Hitt (2002) and Caroli and Van Reenen (2001) Individual managers: Bertrand and Schoar (2003) Competition and firm performance Empirics: Nickell (1996), Syverson (2004), and Aghion, Bloom, Blundell, Griffith, and Howitt (2005) Dynamic theory: Jovanovic (1982) and Hopenhayn (1992) Theory: Schmidt (1997), Raith (2003) and Vives (2004) Productivity dispersion & dynamics Establishments: Baily, Hulten, and Campbell (1992), Bartelsman and Dhrymes (1998), and Jensen, McGuckin and Stiroh (2001), Foster, Haltiwanger and Syverson (2003) Countries: O’Mahony & Van Ark (2004), Caselli (2005) Family firms Empirical: La Porta, Lopez-De- Silanes and Schleifer (1999), Bertrand et al (2004), Villalonga and Amit (2004), Bennedsen, Nielsen, Perez-Gonzales & Woflenzon (2005), Theory: Burkart, Panunzi and Schleifer (2003), Caselli and Gennaioli (2005) Economic History: Landes (1969), Chandler (1994), Nicholas (1999)

11 STEPS TO TRY TO MEASURE MANAGEMENT 1) Developing management practice scoring Scorecard for 18 monitoring, targets and incentives practices 45 minute phone interview of (manufacturing plant) managers 2) Obtaining unbiased responses “Double-blind” Interviewers do not know company performance Managers are not informed (in advance) they are scored 3) Getting firms to participate in the interview Introduced as “Lean-manufacturing” interview, no financials Endorsement of Bundesbank,UK Treasury, Banque de France Run by 10 MBAs (loud, assertive & business experience)

12 Score(1): Measures tracked do not indicate directly if overall business objectives are being met. Certain processes aren’t tracked at all (3): Most key performance indicators are tracked formally. Tracking is overseen by senior management (5): Performance is continuously tracked and communicated, both formally and informally, to all staff using a range of visual management tools MONITORING - i.e. “HOW IS PERFORMANCE TRACKED?” Note: All 18 dimensions and over 50 examples in Bloom & VanReenen (2006).

13 ADDITIONAL CONTROLS FOR BIAS & NOISE 8 INTERVIEWEE CONTROLS Gender, seniority, tenure in post, tenure in firm, countries worked in, foreign, worked in US, plant location, reliability score 3 INTERVIEWER CONTROLS Set of analyst dummies, cumulative interviews run, prior firm contacts 5 TIME CONTROLS Day of the week, time of day (interviewer), time of the day (interviewee), duration of interview, days from project start

14 MANAGEMENT SURVEY SAMPLE US (290), UK, France and Germany (≈150 each) Medium sized manufacturers (100 - 10,000 employees, median ≈ 600) Medium sized because firm practices more homogeneous Manufacturing as easier to measure productivity Obtained 54% coverage rate from sampling frame Response rates uncorrelated with performance measures

15 ADDITIONAL MATCHED DATA WE COLLECTED HR Survey Skills, demographics, hours, organisational characteristics, number of competitors etc. Ownership & Family Survey Shareholders & managerial characteristics, family involvement, family progression rules etc. Performance Data Separately match company accounts - so collect management and performance data from completely different sources Industry and Trade Data OECD

22 CONCERNS WITH OUR MANAGEMENT MEASURE? Three potential issues: 1) Measurement error (classical), but Attenuation downwardly biases our results We try to control for this with “Noise” controls (management & interview characteristics)

23 CONCERNS WITH OUR MANAGEMENT MEASURE? (2) Firm performance-related measurement bias in management score (i.e. the “happy manager” problem), but Surveying methodology using examples tries to minimize this Competition and management positively linked (later) Management-performance link is as important in France & Germany (where managers less likely to “talk up” Anglo- Saxon practices) as it is in UK & US No link between past productivity growth & management Not all questions significant (and not linked to “subjectivity”) Other subjective questions insignificant – i.e. “feel-good” work- life balance questions, organisational devolvement questions So potential problem – but no evidence that major phenomenon

24 CONCERNS WITH OUR MANAGEMENT RESULTS? (3) Reverse causality (management correctly measured but better firm performance causes better management), Yes – but main point of performance estimations is external validity of the measure Also note that if interpretation is effect of management on productivity note that the bias is ambiguous

30 Factors we did not find a significant relationship for Unions: negative but not significant But: (i) sample ≈ 450 firms; and (ii) issues over causation Was negative and significant for two individual practices: Fixing/firing bad performers, Rewarding good performers CEO Pay: no link in levels – but issues over causation Ownership/Governance: positive but insignificant for ownership concentration and board indepedence measures: But sample only UK/US quoted firms (≈ 350) Leverage: nothing with debt/equity – but issues over causation

31 Competition & Models of Management Practices “Exogenous managerial inefficiency” – positive impact Selection models Hopenhayn (1992) or Syverson (2004) “Optimal choice model” – ambiguous impact In contracting models balance between opposing profit and market-size effects (Raith 2003, Vives 2004).

33 FAMILY FIRMS & MANAGEMENT – AN OLD TOPIC Alfred Chandler 1 and David Landes 2 both claimed UK & French industrial decline relative to US & Germany linked to family firms “The Britain of the late 19 th Century basked complacently in the sunset of economic hegemony. Now it was the turn of the 3 rd generation…and the weakness of British enterprise reflected their combination of amateurism and complacency” “French enterprise was family-owned and operated, security- orientated rather than risk-taking, technologically conservative and economically inefficient” 1 Alfred Chandler, “Scale and Scope: The Dynamics of Industrial Capitalism”, (1994) 2 David Landes, “The Unbound Prometheus: Technological Change and Industrial Development in Western Europe from 1750 to the Present”, (1969)

34 WE DO FIND GREATER UK & FRENCH FAMILY MANAGEMENT IN OUR DATA (100 YEARS ON), %UKFraGerUS Family 1 largest shareholder30323010 Family 1 largest shareholder and family CEO 2322127 Family 1 largest shareholder, family CEO & primo geniture 2 151433 1 Family defined as 2 nd generation or beyond (so not the founder). Shareholdings combined across all family members. 2 Based on question: “How was management of the firm passed down: was it to the eldest son or by some other way?”. Non primo geniture alternatives in frequency order: other sons, son in-laws, daughters, brothers, wives, nephews and cousins.

35 WHY DOES FAMILY INVOLVEMENT VARY ACROSS COUNTRIES? Historical differences UK & French tradition of Primo Geniture: [Oxford English Dictionary, 2005] “Feudal rule of inheritance introduced into England by the Norman Conquest. Replaced Teutonic gavelkind. Obligatory until the Statute of Wills [1540]. Still common in many places” US and German tradition of equal division (Menchik, 1980) Estate tax headline rates 1 : on family firms US ≈ 50%France ≈ 25% UK = 0%Germany ≈ 15% 1 Rate on a $25m firm. In practice these taxes are often reduced/avoided by advanced tax planning, although this involves foresight, financial costs and some control loss.

36 FAMILY FIRMS AND MODELS OF MANAGEMENT PRACTICES Likely family impact depends on involvement Ownership but not management probably positive Concentrated ownership so better monitoring Management probably negative Smaller pool to select CEO from Possible “Carnegie” effect on future CEO’s Both effects will be worse with primo geniture (succession of eldest son to CEO position)

Do you fancy meeting up near the factory?” Interviewer “Sorry, but I’m washing my hair every night for the next month….” The British Chat-Up

44 MY FAVOURITE QUOTES: Interviewer: “How many production sites do you have abroad? Manager in Indiana, US: “Well…we have one in Texas…” Americans on geography Production Manager: “We’re owned by the Mafia” Interviewer: “I think that’s the “Other” category……..although I guess I could put you down as an “Italian multinational” ?” The difficulties of defining ownership in Europe

45 MY FAVOURITE QUOTES: The bizarre Interviewer: “[long silence]……hello, hello….are you still there….hello” Production Manager: “…….I’m sorry, I just got distracted by a submarine surfacing in front of my window” The unbelievable [Male manager speaking to a female interviewer] Production Manager: “I would like you to call me “Daddy” when we talk” [End of interview…]

46 Score(1) People are promoted primarily upon the basis of tenure (3) People are promoted upon the basis of performance (5) We actively identify, develop and promote our top performers INCENTIVES - i.e. “HOW DOES THE PROMOTION SYSTEM WORK?” Note: All 18 dimensions and over 50 examples in Bloom & VanReenen (2006).

47 Score(1) Goals are either too easy or impossible to achieve; managers low-ball estimates to ensure easy goals (3) In most areas, top management pushes for aggressive goals based on solid economic rationale. There are a few "sacred cows" not held to the same rigorous standard (5) Goals are genuinely demanding for all divisions. They are grounded in solid, solid economic rational TARGETS - i.e. “HOW TOUGH ARE TARGETS?” Note: All 18 dimensions and over 50 examples in Bloom & VanReenen (2006).
