Labor Market Regulation and Employment Protection

Core Idea

Employment protection legislation (EPL) comprises the set of regulations governing the hiring and — especially — the dismissal of workers: advance notice requirements, severance pay mandates, restrictions on unfair dismissal, and rules governing the use of temporary and fixed-term contracts. EPL is one of the most studied and debated labor market institutions because it creates a fundamental tradeoff: stricter protection reduces involuntary job loss for incumbent workers (insiders) but raises the cost of adjustment for firms, potentially reducing hiring rates and trapping outsiders (the unemployed, youth, new entrants) in precarious or informal employment. The OECD's EPL index, which scores countries on the stringency of their dismissal regulations, reveals enormous cross-country variation — from flexible Anglo-Saxon systems (US, UK) to rigid Continental European systems (France, Italy, Spain) — and this variation has been central to debates about why European unemployment rates diverged from American rates in the 1980s and 1990s.

Explainer

Every country regulates the employment relationship, but the stringency of that regulation varies enormously. At one extreme, the United States operates under employment-at-will — employers can dismiss workers for almost any reason (barring discrimination) with no mandatory notice or severance. At the other extreme, countries like France and Italy require extensive advance notice, mandated severance pay, demonstration of economic necessity for layoffs, consultation with worker representatives, and regulatory approval for collective dismissals. Between these poles lie most countries, with varying combinations of protections that the OECD has codified into its Employment Protection Legislation index since the late 1990s.

The economic analysis of EPL begins with the recognition that dismissal costs function as a tax on labor market adjustment. When firing costs are high, the effective cost of labor includes not just the current wage but the expected future severance payment. This has two symmetric effects. On the firing side, firms retain workers they would otherwise dismiss during downturns, because the cost of severance exceeds the loss from keeping a less-needed worker. On the hiring side, firms are more cautious about taking on new workers during upturns, because each hire represents a potential future firing cost. The first effect stabilizes employment; the second effect reduces job creation. Lazear's (1990) influential paper formalized this insight and showed that under specific conditions, the firing tax could reduce total employment. But Bertola (1990) countered that the two effects could offset each other, leaving the overall employment level largely unchanged while fundamentally altering the dynamics — less turnover, longer job tenures, and longer unemployment spells for those who do lose their jobs.

The empirical evidence on EPL's effects is extensive but not entirely conclusive. Blanchard and Wolfers (2000) argued that rigid labor market institutions (including EPL) interacted with macroeconomic shocks to produce the European unemployment divergence of the 1980s and 1990s — countries with rigid institutions experienced persistent unemployment after oil shocks and demand contractions, while flexible labor markets recovered quickly. OECD studies consistently find that strict EPL is associated with lower labor market flows (fewer transitions between employment and unemployment), longer unemployment duration, lower youth employment, and greater use of temporary contracts. However, the correlation between EPL stringency and the overall unemployment rate is surprisingly weak — suggesting that the hiring and firing effects roughly offset each other on average, even as they dramatically change the composition of employment and unemployment.

The insider-outsider dimension of EPL has attracted particular attention. Lindbeck and Snower (1988) argued that employment protection creates a privileged class of protected workers (insiders) whose bargaining power is enhanced by firing costs, while outsiders — the young, the unemployed, immigrants, and those on temporary contracts — bear the costs of reduced labor market access. This dynamic has been especially visible in Southern Europe, where strict protections for permanent workers coexist with high youth unemployment and widespread use of precarious temporary contracts. Spain's labor market in the 2000s epitomized this dualism: while permanent workers enjoyed strong protections, over a third of the workforce was on temporary contracts with minimal protections and high turnover, creating what economists call a two-tier labor market.

Recent reform trends reflect an attempt to find middle ground. Several European countries have moved toward "flexicurity" — combining moderate employment protection with generous unemployment benefits and active labor market policies (the Danish model) — or have reduced the gap between permanent and temporary contract protections (Spain's 2012 reform, Italy's Jobs Act of 2015). The goal is to preserve a reasonable degree of worker security while reducing the costs of rigidity: slower job creation, labor market segmentation, and reduced economic dynamism. The optimal level of employment protection remains contested, depending on how one weighs job security for incumbents against job access for outsiders and overall labor market efficiency.
