197. Moving workers across Europe

Episode Summary

Executive Summary: The episode explains how the EU’s posting policy lets firms temporarily send workers abroad while keeping them on home-country contracts, and why this became politically explosive. Using new research, Mathilde Munoz shows that posting boosted cross-border integration and profits, but reduced employment for some host-country workers and required host-country minimum wages to redistribute gains and prevent race-to-the-bottom pressures.

Main Topics: Origins of the European Union and the four freedoms (Priority: 5/5): The discussion traces EU integration from postwar ideas of a unified Europe to the Treaty of Rome and the four freedoms: goods, services, people, and capital. How the EU posting policy works (Priority: 5/5): Posted workers are temporarily sent by a firm in one country to perform services in another, staying on the sending country’s employment contract while host-country labor rules partly apply. Who posted workers are and where they work (Priority: 4/5): The episode describes the industries, demographics, and scale of posted workers, highlighting that they are mostly male, older, and concentrated in blue-collar sectors. Effects on host-country labor markets (Priority: 5/5): In France, exposure to posted workers reduced employment in affected sectors without substantially lowering wages, with adjustment occurring mainly through hiring and labor-force exits. Effects on sending-country firms and workers (Priority: 4/5): Portuguese firms expanded sales and profits from posting, while posted workers themselves received wage gains that were smaller than firm gains. Minimum wage regulation and political backlash (Priority: 5/5): Host-country minimum wage rules were central to the policy’s legitimacy, and attempts to remove them sparked major protests and helped trigger French backlash against EU integration. Trade, regulation, and limits of integration (Priority: 5/5): The episode argues that differences in labor standards can shape trade flows, and that integration requires both economic liberalization and political support for redistribution.

Key Arguments: The EU posting policy is a hybrid of trade and migration policy, because firms export services by moving workers temporarily across borders. Host-country minimum wage rules are crucial because they determine whether gains from integration are shared with workers rather than captured only by firms. Posted-worker flows are economically meaningful, not marginal: they are large enough to matter for labor markets, trade, and tax revenue. Host-country adjustment happens mostly through employment rather than wages, reflecting rigid wage-setting in places like France. Sending-country firms benefit substantially from access to foreign demand, with small firms scaling up much like traditional goods exporters. Posted workers themselves gain wages, but these gains are limited relative to employer gains, implying rents are split among firms, workers, and customers. The policy reverses the usual fiscal story of migration: taxes and social-security payments remain tied to the sending country, so sending states gain revenue. The Bolkestein proposal showed that voters react strongly when integration appears to be driven by regulatory arbitrage rather than convergence. Cross-border trade patterns in services can be strongly affected by domestic labor-market rules, as shown by Germany’s minimum wage reform. Economic integration is politically fragile unless paired with redistribution, social convergence, and institutional legitimacy.

Data Points: Foundational EU freedoms: 4 - Free movement of goods, services, people, and capital under the Treaty of Rome. Treaty of Rome year: 1957 - Core member states signed the treaty and committed to the four freedoms. Maastricht Treaty period: Mid-1990s - Introduced deeper political union and central EU institutions. Posted workers in 2019: Roughly 2 million full-time equivalent - Scale of workers engaged in the EU posting policy. Share of total European employment: About 2% - Approximate size of posted work relative to total employment stock in Europe. Share of EU GDP: Roughly 2% - Flows triggered by posting contracts as a share of GDP. Compared with intra-EU goods trade: About 10% - Posting-related flows relative to trade in goods within the EU. Compared with intra-EU services trade: About one-third - Posting-related flows relative to trade in services within the EU. Share of posting flows to rich member states: About 85% to 90% - Most posting flows go from low-wage to high-wage countries. Share of posted workers who are men: 95% - Posted workers are overwhelmingly male. Share of posted workers in blue-collar jobs: More than 70% - Most posted workers do not need a college education. Typical age of migrants: Around 25 - Age at migration for European migrants in the comparison. Typical age of posted workers: Closer to 40 - Posted workers are older than typical migrants. Employment effect in exposed French sectors: 6% relative decrease - French employment fell in sectors and regions more exposed to posted workers. Wage effect in France: Pretty constant / no major decrease - Wages stayed stable despite employment declines. Wage gain for posted workers from Portugal: 14% to 15% - Workers sent abroad saw substantial wage increases. Meat-processing wage gap in Germany before 2015: €3/hour vs €16/hour - Posted workers versus German workers in the same industry before the minimum wage reform. Foreign supply share in German meat processing before 2015: 50% - Half of workers in the sector were sent by foreign suppliers of services. Post-2015 change in imports of services in exposed German industries: Almost cut by half - After Germany introduced a binding minimum wage for foreign suppliers. Current level of those imports after reform: Almost non-existent - Service imports in exposed industries largely collapsed after the wage rule. French support for European integration after Bolkestein proposal: Dropped from 60 to below 50 - Support among French voters fell sharply when the directive was introduced.

Pivotal Quotes: "one day we'll come where the only fields of battle will be markets opening to trade" — Mathilde Munoz: On the early intellectual vision of a peaceful, integrated Europe. "it's 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 under the posting policy. "economic integration is tough, and you need to be very creative in terms of policy and intervention to foster it" — Mathilde Munoz: Her main takeaway for policymakers at the end of the interview.

Implications: The episode suggests that market integration can expand trade and firm growth, but only remains politically durable if workers and voters see fair distribution. Future EU-style integration likely needs stronger social policy and institutional convergence, not just freer markets.
