Why is productivity growth so low (in the 'Second Machine Age')? Prof. Dr. Alfred Kleinknecht (Emeritus) Visiting Fellow of WSI, Hans-Böckler-Stiftung, Düsseldorf www.alfredkleinknecht.nl The labor productivity growth slowdown in advanced OECD countries (Source: https://www.conference-board.org/data/economydatabase/ Why is the productivity crisis relevant? (1) You can achieve economic growth by: 1. Working more hours 2. Working more productive hours (i.e. more value added per hour = higher labor productivity (through better technology and organization) If Option 2 fails, you need to use option 1 → thanks to the productivity crisis, the US, Japan and West-Europe may get a highly labor-intensive growth! … as far as there is still growth (?) Why is the productivity crisis relevant? (2) Value added per working hour is (by definition) equal to National Income Hence, with low labor productivity growth, there is little to be distributed (extra) between labor, capital and the public sector Possible consequences: Pressure on public expenditures Tendency towards ‘precarization’ of work (working poor, many atypical jobs) Erosion of the middle class Three explanations of the productivity slump (1) A Keynesian explanation: weak effective demand and investment ('balance sheet recession' after 2008) Richard C. Koo: The world in balance sheet recession: causes, cure, and politics, in: Real-world Economics Review, 1911 (issue 58) S. 19-36; http://www.paecon.net/PAEReview/issue58/Koo58.pdf Three explanations of the productivity slump (2) A low technological opportunities explanation: Exhaustion of the American IT Boom David Gordon, The rise and fall of American growth, Princeton Univ. Press, 2016 The labor productivity growth slowdown in advanced OECD countries (Source: https://www.conference-board.org/data/economydatabase/ US ITBoom Three explanations of the productivity slump (3) A varieties-of-capitalism explanation: The Emergence of Supply-side Economics After the 'Golden Age of Capitalism' (1948-1973) growth rates declined substantially: rise of unemployment, high inflation ('stagflation' etc.). This was a breeding ground for a revolution in the economics discipline: from 'demand-side economics' (Keynes) to 'supplyside economics' (Hayek, Friedman) and a sharp attack on the Keynesian welfare state. What does supply-side economics mean? Sobering of the welfare state Privatization & deregulation an a broad scale No more anticyclical fiscal policy; only monetary policy More inequality of incomes ('performance must pay!') No full employment but a (sufficiently high) level of ‘natural‘ unemployment Deregulation of labor markets – Easy firing and (downwardly) flexible wages "There is no such thing like society …" (Margret Thatcher) But Supply-side Economics had a limited reach: P. Hall & D. Soskice, Varieties of capitalism, Oxford University Press, 2001 distinguish two types of capitalism: 1. Anglo-Saxon ‘Liberal Market Economies’ (US, UK, Canada, New Zeeland, Australia) with 'flexible' labor markets (weak protection of labor) 2. 'Coordinated Market Economies' ('Old-Europe' + Japan) with ‘rigid’ labor markets (strong protection of labor) Complaint by supply-siders: Old Europe is too slow in adopting 'structural reforms' of labor markets! A comparison between Liberal Market Economies (LME) and Coordinated Market Economies (CME) Comparing some core variables for Liberal Market Economies (US, UK, Canada, New Zealand, Australia) versus: Coordinated Market Economies (proxy: EU-12) Labour market deregulation leads to moderate wage growth!

Luxemburg 120 100 80 60 40 20 0 Eurosclerosis!? Core question: Does wage growth influence labor productivity growth? Traditional argument: Growth of labor productivity → wage growth (end of story) My argument (to be proven): There must also be a causal link: wage growth → labor productivity growth Doubts: W. J. Jansen: 'Kleinknechthypothese mist empirisch bewijs!', Economisch Statistische Berichten, Vol. 89 (Sept. 2004), p. 418. Rationale? • • • • Speed of capital – labour substitution (Hicks) Vintage effects (Tjan & Hartog) Induced Innovation (van Weizsäcker; Kennedy) Creative destruction (Schumpeter) Slow diffusion of automation technology Key finding from panel data estimates: A one-per cent wage decline (increase) leads to 0.35 ̶ 0.45% lower (higher) growth of value added per labour hour Sources: Vergeer & Kleinknecht 2011: The impact of labor market deregulation on productivity, Journal of Post-Keynesian Economics, Vol. 33(2): 369-404. Vergeer & Kleinknecht 2014: Does labor market deregulation reduce labor productivity growth? International Labour Review, Vol. 153(3): 365-393. Evidence at macro-level is consistent with findings from firm-level studies: High shares of flexible labour in a firm are negatively related to: Labour productivity growth The probability to innovate … and flexible labour enhances the growth of management bureaucracies for monitoring & control Recent paper: Alfred Kleinknecht, Flore N. van Schaik & Haibo Zhou (2014): Is flexible labour good for innovation?, in Cambridge Journal of Economics, Vol. 38(5): 1207-1219. Summarizing: Deregulation of labour markets changes power relations between capital and labour → lower wage growth … which has no influence on GDP growth, but … … causes a slower diffusion of advanced process technology → lower growth of GDP per working hour … and hence a labour-intensive growth path ... but with low productivity growth there is little to be (extra) distributed and this causes pressure towards: – 'Precarization' of work – Pressure for budget cuts in the public sector – Problems financing demographic change A similar story holds for the Netherlands … As a response to the Dutch Disease (ca. 1975-85), trade unions made very modest wage claims during the past 35 years … … problems with effective demand were solved by means of high current account surpluses … … and The Netherlands experience a strong job growth! Broad national consensus in the Netherlands in favour of "Loonmatiging" (= very low wage claims) Low wage strategy brought no higher GDP growth (other than expected by the mainstream)!

(1) Deregulation of labor markets leads to “more dynamism”, i.e. higher job turnover, which in turn reduces loyalty and commitment of workers: → more leaking of trade secrets and technological knowledge (i.e. stronger externalities) → more need for monitoring & control → thicker management bureaucracies (next sheet) Share of managers in the working population (19 OECD countries, 1984-1997) Norway Spain Greece Sweden Italy Switzerland Belgium Ireland Germany Portugal Japan Denmark Finland Austria Netherlands U.K. Australia USA Canada According to De Beer (2001), the Dutch figure increased from 2% to 6% during 19781998 (the period of ‘flexibilization’ of the Dutch labour market) 0 5 10 15 Managers as a percentage of the non-agrarian working population Why are the CMEs outperforming LMEs in labor productivity growth? (2) Deregulation of labor markets and higher job turnover lead to: Lower investment in firm-financed training Lower benefits from “learning by doing” and weaker “organizational memories” (learning from past failures) More power for top management and less critical feedback from the shop floor → more autocratic management Why are the CMEs outperforming LMEs in labor productivity growth? (3) Flexible firing increases risk-aversion on the shop floor: in the selection of innovative solutions, people that are easy to fire will choose less risky options → too little progression! Empirical support using patent and patent citation data: Acharya, Viral V., et al. (2010): Labor laws and innovation, NBER Working Paper 16484. Cambridge, MA: NBER Why are the CMEs outperforming LMEs in labor productivity growth? (4) People on the shop floor possess much of the (tacit) knowledge required for implementation of process innovations. People threatened by easy firing have incentives to hide knowledge relevant to labour-saving process innovations (Lorenz, 1992, 1999) More generally, people that are easy to fire have strong incentives hiding information about how their work can be done more efficiently (exploiting information asymmetry between management and the shop floor) → in a hire & fire regime you make poor use of the (tacit) knowledge of your workers Why are the CMEs outperforming LMEs in labor productivity growth? (5) CMEs tend to have more centralized wage negotiations; wage increases force technological laggards to modernize equipment Other than a “Garage Business” model of innovation, a “Routinized Innovation Model” requires a continuous accumulation of (often: tacit) knowledge → need for continuity of personnel "Tacit knowledge" = poorly documented, ill-codified knowledge from experience (Polanyi 1966) Much depends on the type of innovation model: Flexible labor has no influence on innovation Schumpeter I innovation model: 'Entrepreneurial model': start-ups, inventor-entrepreneur ('Garage business'). Knowledge base: General (and generally available) knowledge Schumpeter II innovation model: 'Routinized Innovation': Professional R&D labs in larger firms. Continuous improvement of products, processes or systems requires continuous accumulation of knowledge. Knowledge base: Historically accumulated, firm-specific and often 'tacit' knowledge (i.e. ill-documented knowledge from personal experience) Flexible labor has a strongly negative influence on innovation and productivity growth Conclusion: Supply-side economists correctly argue: Deregulation of labor markets (weak trade unions, no minimum wages, poor social benefits, downwardly flexible wages etc.) leads to more employment … … but they forget to tell us that this is at the cost of low labor productivity growth … … and hence somebody needs to sacrifice income … … in real life we get a growing class of working poor on precarious jobs … … and an erosion of the middle class (Trump effect!) General conclusion: What is useful from a neoclassical view ('how to allocate scarce resources efficiently') … … can be counter-productive from a Schumpeterian view ('how to make resources less scarce through innovation?') A legacy of Schumpeter: (Static) allocative efficiency is no good milieu for innovation! "Perfect competition … is a condition for optimal allocation of resources … But … introduction of new methods of production and new commodities is hardly conceivable with perfect … competition … And this means that the bulk of … economic progress is incompatible with it. As a matter of fact, perfect competition is and always has been temporarily suspended whenever anything new is being introduced …". Joseph A. Schumpeter: Capitalism, Socialism and Democracy, London: Allen & Unwin 1943, p. 104-105. Rounding up: Two alternative strategies for capitalism Supply-Side Economics: Through ‘Structural Reforms’ to flexible labor markets: easy firing + poor welfare state: A much more unequal income distribution Overall poor labor productivity growth → many (but often precarious) jobs! European Social Model: Rigid labor markets + strong welfare state + tough investments in education and research: High speed of labor-saving technical change → Many highly productive jobs for protected insiders, but: Poor overall growth of labor input, and therefore … Shorter working times rather than wage claims Reduce labor supply!
