Does Unionization Rate Matter for Labor Productivity Level: Panel Evidence

Öz

This study investigates the effect of unionization rate on labor productivity by using thirteen distinct labor productivity indicators. The data used in the analyses is unbalanced data covers the periods between 2000 and 2013 for fifty one countries. There are two opposite empirical findings on the issue in the literature. While some of the studies find negative association between unionization and productivity, the others find positive association between unionization and productivity. Hence the impact of unionization on productivity is ambiguous. The main finding of the study reveals a strong and statistically significant negative association between unionization rate and labor productivity and this finding remains valid in all models. Hence we may conclude that countries with higher unionization rate face lower labor productivity level.

Sendikalaşma Oranı İşgücü Verimliliği İçin Önemli midir?: Panel Kanıt

Öz

Bu çalışma on üç farklı işgücü verimlilik göstergesini kullanarak sendikalaşma oranının işgücü verimliliği üzerindeki etkisini incelemektedir. Analizlerde kullanılan veri seti dengesiz panel veri olup 2000-2013 yılları arası ve elli bir ülke içindir. Literatürde konu hakkında iki zıt ampirik bulguya rastlanmaktadır. Çalışmalardan bazıları sendikalaşma ile verimlilik arasında negatif ilişki tespit ediyor iken diğerleri pozitif ilişki bulmaktadır. Bundan ötürü sendikalaşmanın verimlilik üzerindeki etkisinin yönü belirsizdir. Çalışmanın ana bulgusu sendikalaşma oranı ile işgücü verimliliği arasında kuvvetli ve istatistiksel olarak anlamlı negatif bir ilişkinin olduğunu ortaya koymaktadır. Bundan dolayı daha yüksek sendikalaşma oranına sahip ülkelerin daha düşük işgücü verimlilik düzeyi ile karşı karşıya kaldığı sonucunu çıkarabiliriz.
