Questions • Wage growth: Did real wages grow? Or did they stagnate? • Decoupling: Did wages increase in tandem with productivity? Or did
wages decouple from productivity? • Unemployment: How did unemployment evolve before and after the
Great Recession? • Wage Inequality: Did wages increase more at the top than at the
bottom of the wage distribution?
• Focus: Germany and France (Paper: nine advanced countries) • Data Source: OECD Economic Indicators • Time period: 1995-2016

What Can Account for the Divergent Experience of Germany and France?
• Our focus: The role of unions in the wage setting process (Dustmann, Fitzenberger, Schönberg, Spitz-Ӧner, JEP, 2014)
• Other factors are at play as well:
• Decline in labor share: the rise of ‘superstar’ firms (Autor et al., 2017; Kehrig and Vincent, 2017; De Loecker and Eeckhout, 2017)
• Technological change (Autor et al., 2003; Dustmann, Ludsteck and Schönberg, 2009)
• Structural problems; labor market inflexibilites • Hartz reforms

Alice Kügler 1, Uta Schönberg](https://reader031.vdocument.in/reader031/viewer/2022022606/5b7fdb7a7f8b9a2a088c93f2/html5/thumbnails/23.jpg)
Unions in Germany and France: Similarities
• Negotiations between employer federations and trade unions predominantly take place at industry level
• Negotiations take place (most importantly) over pay and working conditions
• Agreed union wages typically vary by skill and act as minimum wages
![Page 24: Productivity Growth, Wage Growth and Unions · Productivity Growth, Wage Growth and Unions ECB Forum on Central Banking, June 20 th 2018, Sintra, Portugal . Alice Kügler 1, Uta Schönberg](https://reader031.vdocument.in/reader031/viewer/2022022606/5b7fdb7a7f8b9a2a088c93f2/html5/thumbnails/24.jpg)
Unions in Germany and France: Differences Germany • Firms’ union recognition is
to large extent voluntary o Firms can opt out of union
agreements o New firms can decide not to
recognize union agreements
• Opening clauses: many union agreements allow for downward deviations at the firm level
• Until recently: No national minimum wage
France • State extends union
agreements to virtually all firms in the sector
• Until recently: Downward deviations at firm level not possible
• National minimum wage set at high level
Government plays an active role in wage setting process in France Wage negotiations are more consensus-based in Germany

Germany’s Experience: De-Unionization • After fall of Iron Curtain:
Germany was burdened with reunification; moving production abroad became a credible threat Paying high union wages became increasingly costly; firms started to opt out of union agreements

German Unions Adapted … and Were Willing to Make Concessions
• Opening Clauses: downward deviations from industry-wide agreements at firm level oPrevalence (manufacturing): 1995: 5% of union agreements allowed for opening clauses 2004: 60%
Further decentralization of the wage setting process within the formal unionized sector
• Wage restraint shown by unions Klaus Zwickel: low wage demands—based on inflation rather than productivity increases—in exchange for more job creation

Germany vs France
• Decentralization of wage setting process in Germany from the industry to firm and individual level occurred without intervention of the German government, without legal changes
• Differences in the system of industrial relations o Automatic extension of union agreements to all firms o Legalized increases in the minimum wage
prevented France from responding in a similar way higher wage growth in France, in particular at the bottom of the wage distribution increase in competitiveness—measured as a reduction in unit labor costs —in Germany relative to France lower unemployment in Germany?
![Page 32: Productivity Growth, Wage Growth and Unions · Productivity Growth, Wage Growth and Unions ECB Forum on Central Banking, June 20 th 2018, Sintra, Portugal .

The Recent Experience – Some Convergence? • In economic outcomes
oWage growth has picked up in Germany and now closely follows productivity growth
o Since 2010: Wage inequality has stopped increasing in Germany oDe-unionization seems to have slowed down somewhat oUnemployment lower in Germany than in France
• In terms of systems of industrial relations oGermany introduced a national minimum wage in 2015
o Ratio minimum wage/median: 0.49 in Germany, 0.61 in France o Labor market reforms under Hollande and Macron
Shift in wage negotiations from the industry level to the firm level

Unions Protest Against Macron Reforms
• Unions have called for multiple protests against Macron’s reforms.
• 18 hours after Macron’s victory: Demonstrations supported by dozens of brances of CGT and SUD unions.
«There will be no grace period, no truce» (Romain Altmann, head of Info’Com-CGT union)
