Introduction
The minimum wage is much more than just a labor market parameter—it is the foundation of an economic model and a tool of social policy. This article analyzes its evolution from the era of the transformation shock to contemporary EU regulations. You will learn how the Kaitz index measures wage adequacy, why inflation turns the wage into a "moving target," and how Directive 2022/2041 is changing the rules of dialogue between business and the state. Understanding these mechanisms is crucial for assessing whether the minimum wage protects the most vulnerable or becomes a barrier to development.
Four Functions of the Wage: From Protection to Motivation
During the transition period, the minimum wage served four main roles: protective (safety net), income (public spending lever), stabilization, and regulatory. A lack of wage protection generates enormous institutional costs, leading to the breakdown of social norms. However, linking the wage to the social welfare system can be problematic—when it serves as an anchor for benefits, a budget "under siege" forces its value to be artificially suppressed.
An excessively high minimum wage generates unemployment among vulnerable groups, for whom it becomes a barrier to entry. High wage thresholds also fuel the gray market, where informality becomes an escape from costs. In this context, the minimum wage eliminates the cheap labor model, forcing the state to effectively enforce the law, without which any norm remains merely a suggestion.
The Kaitz Index and the Debate Over Employment Impact
The Kaitz index, which is the ratio of the minimum wage to the median wage, is the primary measure of wage adequacy. In academia, a debate persists over its impact on the market: the Card-Krueger model suggests that increasing the minimum does not necessarily destroy jobs, while Neumark and Wascher point to risks for low-skilled workers. These differences stem, in part, from the phenomenon of monopsony—a situation where employer dominance allows wages to be suppressed below market rates.
It is important to remember that inflation reduces the real value of the lowest wages, undermining the meaning of social promises. If indexation does not keep pace with rising prices, worker protection becomes illusory. On the other hand, rapid increases in low-productivity sectors can trigger a wage-price spiral, making the setting of the minimum wage a difficult balancing act between social justice and economic reality.
The EU Directive and the Future of Automation
Directive 2022/2041 introduces a new framework for wage-setting, emphasizing tripartism and social dialogue. The EU sets indicative thresholds (60% of the median or 50% of the average wage) and obligates member states to strengthen collective bargaining. Although a recent CJEU ruling confirmed that the EU cannot directly decree rates, the pressure for procedures and transparency is growing. For business, wage predictability becomes key, as it stabilizes conditions for investment planning.
Rising labor costs, combined with demographic trends, inevitably accelerate robotization and the automation of services. The minimum wage becomes a signal for deep economic restructuring. The modern model requires that adjustments be linked to productivity, which helps avoid the low-productivity trap and builds margins on innovation rather than exploitation.
Summary
The minimum wage, like the face of Janus, looks back at the transition's past and forward to the future of automation. Will we be able to find a middle ground between worker protection and the incentive for innovation before the labor market turns into an impassable labyrinth? An effective system requires moving away from arbitrary political decisions toward stable procedures, where an inflationary component protects purchasing power and collective bargaining accounts for sectoral specificities. Paradoxically, it is within this constant tension that the opportunity to create a more just and efficient economic model lies.
