197. Moving workers across Europe

Episode Summary

Executive Summary: The episode explains the EU’s posting policy—how firms temporarily send workers across borders—and shows it is a major, controversial channel of European integration. Drawing on new research by Mathilde Munoz, it finds posted-worker flows are large, concentrated in low- to high-wage routes, raise employer profits and worker wages in sending countries, but reduce employment in exposed French sectors and are shaped strongly by host-country labor rules like minimum wages.

Main Topics: Origins of European integration and the four freedoms (Priority: 5/5): The conversation traces the EU from postwar integration ideals and the Treaty of Rome to the four economic freedoms: goods, services, people, and capital. How the posting policy works (Priority: 5/5): Posting lets a firm in one EU country temporarily send its employees to another country to deliver services while remaining employed by the home firm. Labor regulation and minimum wage conflict (Priority: 5/5): The episode explains the unusual EU rule allowing host countries to impose minimum wages on posted workers, and how this became politically explosive. Data on posted workers and who they are (Priority: 4/5): Munoz’s research builds new data showing posted workers are mostly male, older, and blue-collar, distinct from typical migrants. Economic effects in receiving countries (Priority: 4/5): The research finds posted-worker exposure lowers employment in affected French sectors, with little wage adjustment and limited reallocation into other jobs. Economic effects in sending countries and firms (Priority: 4/5): Posted-worker contracts boost sales, hiring, and profits for small exporting firms in countries like Portugal, while workers receive meaningful wage gains. Trade, institutions, and political backlash (Priority: 5/5): The episode links labor-regulation differences to trade flows and to the backlash against the Balkenstein directive and the French EU constitutional referendum.

Key Arguments: European integration was designed not just to eliminate tariffs but to harmonize market rules, making labor mobility and service delivery central to the project. The posting policy is a major but undercounted part of EU integration, functioning as a hybrid trade-and-migration channel rather than a standard goods trade flow. Host-country labor standards matter: minimum wages significantly shape the competitiveness of posted services and the wages workers receive. In France, exposure to posted workers reduced employment in affected sectors by about 6%, but wages of incumbent workers did not fall much, indicating adjustment mainly through jobs rather than pay. Posting benefited firms and workers in sending countries: firms expanded sales and profits, and workers received substantial wage gains of about 14-15%. Most of the wage gains for posted workers appear to come from host-country minimum wage rules, showing redistribution depends on regulation. The policy also reverses fiscal effects of migration, increasing tax and social-security revenue in sending countries rather than in host countries. The Balkenstein controversy showed voters can reject integration if they think trade is driven by institutional arbitrage rather than fair competition. Germany’s 2015 minimum-wage reform provides evidence that labor regulations can substantially reduce cross-border service imports when foreign firms must comply.

Data Points: Treaty of Rome year: 1957 - Core member states committed to the four economic freedoms. Posted workers in Europe (FTE): Roughly 2 million in 2019 - Scale of the posting policy in full-time-equivalent terms. Share of total European employment: About 2% - Posted-worker employment stock relative to overall employment. Share of EU GDP represented by posting flows: Roughly 2% - Value of posting contracts as economic activity. Posted flows as share of EU goods trade: About 10% - Comparison of posting flows to intra-EU goods trade. Posted flows as share of EU services trade: About one-third - Posting flows relative to all services trade within the EU. Share of posted workers who are men: 95% - Gender composition of posted workers. Share of posted workers in blue-collar jobs: More than 70% - Educational/occupational profile of posted workers. Typical age of European migrants: Around 25 - Age at migration for comparable migrant workers. Typical age of posted workers: Closer to 40 - Posted workers are older than typical movers. Employment effect in exposed French sectors: 6% relative decrease - Impact of posted-worker exposure on French employment. Wage effect in France: Pretty constant / little change - Incumbent wages in exposed sectors did not significantly fall. Worker wage gains in Portugal after posting: 14% to 15% increase - Posted workers earned more after being sent abroad. German meat-processing posted-worker wage before 2015: €3 per hour - Average wage of posted workers in Germany before the national minimum wage. German meat-processing wage for German workers before 2015: €16 per hour - Comparison wage for domestic workers in the same industry. Foreign-supplied labor share in German meat processing before 2015: 50% - Share of workers in the industry sent by foreign service suppliers. Effect of Germany’s 2015 minimum wage on imports of services: Almost cut by half - Service imports in exposed industries fell sharply after the reform. French referendum support for European integration: Fell from 60 to less than 50 - Support dropped after the Balkenstein directive controversy. Year of Balkenstein directive proposal: 2005 - Proposal to remove minimum-wage requirements for posted workers. Year of German minimum wage introduction: 2015 - Reform made minimum wage binding for foreign service suppliers too.

Pivotal Quotes: "one day will come where the only fields of battle will be markets opening to trade" — Victor Hugo (quoted by Mathilde Munoz): Used to frame the long intellectual history of European integration. "It is the only time in the EU where one country is actually allowed to impose its domestic standards to foreign firms." — Mathilde Munoz: Explaining the host-country minimum wage rule for posted workers. "The main overall takeaway is that economic integration is tough and you need to be very creative in terms of policy and intervention to foster it." — Mathilde Munoz: Her concluding lesson for policymakers.

Implications: EU integration depends on balancing mobility with social protection. Posted workers can boost firms and sending-country incomes, but without rules like minimum wages they can trigger backlash, reduce jobs in host countries, and undermine political support for the single market.
