Using firm-level data from nine developing countries we demonstrate that (a) certain institutions like restrictive labour market regulations that are considered to be bad for economic growth might be beneficial for production efficiency, whereas (b) good business environment which is considered to be beneficial for economic growth might have an adverse impact on production efficiency. We argue that our results suggest that the debate about the implications of institutional quality is far from being over, and classification of institutions into "good" and "bad" might be premature.
