A startling fact of firm level productivity analysis is the large and persistent differences in both labour … productivity and total factor productivity (TFP) between firms in narrowly defined sectoral classes. The competitiveness of an … industry is potentially an important factor explaining this productivity dispersion. The degree of competition has also …

A common problem is that most firm level dataset do not contain information on … output prices of firms which makes it difficult to distinguish between productivity differences and differences in market … power between firms.

Studies of firm-level data have shown that there is a huge dispersion of productivity across firms even when industries … productive. The formers' convergence could therefore constitute an important part of productivity growth at the macroeconomic … which can explain it. Productivity convergence was stronger for labour productivity than for total factor productivity. But …
