Labour Productivity, Wages, and Inflation: Evidence from Selected Central and South-East European Countries

Abstract

The relationship between inflation, worker wages, and labour productivity growth has been a widely discussed topic among academics in recent decades. Labour productivity is a critical component for maintaining and improving the competitiveness of national economies and establishing sustainable economic growth. The increase in labour productivity serves as the foundation for increasing workers' wages, thereby enhancing their purchasing power and overall well-being. However, empirical data from Southeast European countries indicate that labour productivity growth rates have been insufficient to enable catch-up with their Western European counterparts. Additionally, these countries have experienced significant inflation rates in recent years, resulting in a notable decline in real wages for workers. Therefore, the gap between labour productivity and workers' wages has not only failed to diminish but has, in fact, widened over the past few decades.
 The primary objective of this paper is to examine the interrelationships among labour productivity, workers' wages, and inflation in Central and Southeast European countries, specifically the Balkan EU countries, Balkan non-EU countries, and the Visegrád group of countries. The findings reveal a short-term causality among inflation, labour productivity, and the statutory minimum wage in these three groups of countries. Furthermore, there is evidence of a bidirectional causal relationship running from the minimum wage and inflation to labour productivity, and vice versa, in the short term. Additionally, the introduction of a minimum wage shock significantly influences the future values of labour productivity and inflation. The adverse effects of an externally induced increase in the statutory minimum wage are particularly noticeable in Western Balkan non-EU countries.
