Labor unions and collective bargaining

Although coverage of collective bargaining agreements has been declining for decades in most countries, it is still extensive, especially in non-Anglo-Saxon countries. Strong unions may influence firms' incentives to invest in capital, particularly in sectors where capital investments are sunk (irreversible), as in research-intensive sectors. Whether unions affect firms' investment in capital depends on the structure and coordination of bargaining, the preference of unions between wages and employment, the quality of labor-management relations, the structure of corporate governance, and the existence of social pacts, among other factors.

Alternative dispute resolution procedures such as arbitration and mediation are the most common methods for resolving wage, contract, and grievance disputes, but they lead to varying levels of success and acceptability of the outcome depending on their design. Some innovative procedures, not yet implemented in the real world, are predicted to improve on existing procedures in some ways. Controlled tests of several procedures show that the simple addition of a nonbinding stage prior to binding dispute resolution can produce the best results in terms of cost (monetary and “uncertainty” costs) and acceptability.

In-plant alliances are plant-specific deviations from sectoral collective agreements related to wages and working time that are intended to hold down labor costs. These agreements enable firm-level reorganizations to respond to an imminent economic crisis or to improve competitiveness. They also encourage social partners to take greater responsibility for employment issues. Both unions and works councils agree to such contracts because they see them as helpful in avoiding severe employment losses. Thus, these alliances substantially unburden public employment policy.

In many countries, the wage floors and working conditions set in collective contracts negotiated by a subset of employers and unions are subsequently extended to all employees in an industry. Those extensions ensure common working conditions within the industry, mitigate wage inequality, and reduce gender wage gaps. However, little is known about the so-called bite of collective contracts and whether they limit wage adjustments for all workers. Evidence suggests that collective contract benefits come at the cost of reduced employment levels, though typically only for workers earning close to the wage floors.

The micro- and macroeconomic effects of the declining power of trade unions have been hotly debated by economists and policymakers, although the empirical evidence does little to suggest that the impact of union decline on economic aggregates and firm performance is an overwhelming cause for concern. That said, the association of declining union power with rising earnings inequality and the loss of an important source of dialogue between workers and their firms have proven more worrisome if no less contentious. Causality issues dog the former association and while the diminution in representative voice seems indisputable any depiction of the non-union workplace as an authoritarian “bleak house” is more caricature than reality.

Countries with strong industrial relations institutions and well-established social dialogue often perform well in terms of economic growth and social cohesion. The weak and fragmented bargaining and low levels of union coverage in Central and Eastern Europe (CEE) raise concerns about these countries’ potential to maintain competitiveness, tackle demographic and macroeconomic challenges, and catch up with Western European economic and social standards. There is evidence that unions in CEE continue to protect their members and generate wage premiums, despite their institutional weaknesses.
