Abstract

Celem artykułu jest zmierzenie skali obciążenia oszacowań luki płacowej kobiet, w warunkach, gdy wydajność nie jest obserwowalna. Korzystamy z unikatowych danych jednostkowych dotyczących wydajności i wynagrodzeń dla 2 292 pracowników polskiej firmy zajmującej się handlem detalicznym w branży odzieżowej. Korzystamy z parametrycznych metod dekompozycji do oszacowania skorygowanej luki płacowej z uwzględnieniem i bez uwzględnienia miar wydajności. Wyniki wskazują, że obciążenie wynikające z pominięcia miar wydajności jest istotne statystycznie i wysokie w sensie ekonomicznym, w niektórych specyfikacjach zasadniczo zmienia wnioskowanie o występowaniu nieuzasadnionej różnicy w wynagrodzeniach pomiędzy kobietami i mężczyznami. Większość oszacowań tzw. skorygowanej luki płacowej nie uwzględnia miar produktywności, głównie z uwagi na brak stosownych miar w dostępnych zbiorach. Choć wyniki zawarte w tym artykule dotyczą tylko jednego przedsiębiorstwa, dają przesłanki, by stwierdzić, że oszacowania, którymi posługuje się literatura, może cechować znaczne obciążenie.
