Inside the black box: compensation structures of efficient Yugoslavian firms

The main purpose of the research discussed in this paper has been to try to understand the main determinants of labor productivity within a firm from the perspective of the worker through a model and econometric application. Understanding why workers do the best they can or "just make time" is at the heart of the issue. The results indicate that on the basis of these data there is support for the hypothesis that an hierarchical effort function of the workers may indeed help explain variations in firm productivity.
