This paper discusses ways of strengthening the competitive environment in order to help boost productivity performance in various sectors of the Danish economy. It looks at a number of indicators of the strength of competition — including price levels, industrial concentration and product market regulation — and it discusses the appropriateness of the competition legislation framework. The paper then focuses on the large public sector, which has been slow to open up to competition, partly because of regulatory restrictions but also because some local governments are too small to handle tenders and provide an attractive market for private providers. The paper also looks at the process of liberalising network industries and at various regulations that still impede effective competition in a number of other sectors, including construction, housing, distribution and professional services.
