Spoiler: The historically meagre productivity growth of the Swedish Construction industry is a serious problem. Low productivity growth for an industry does not have to be a problem if the industry is small relative to the rest of the economy. But it is problematic when a large industry’s share in the economy is increasing over time at the same time as its productivity growth is stagnating. The Swedish Construction industry’s contribution to overall Swedish productivity growth is almost as small as the public sector’s contribution.
Unless the Construction industry’s productivity growth increases, the other industries’ productivity growth will have to increase. The increases will have to be continuously higher as long as the Construction sector’s share of the economy keep increasing. The reasons behind the weak productivity growth are well-known. Weak competition, many and complex regulations, municipal monopoly of the planning process for buildings, and other factors leading to high entry costs making it difficult for new firms enter the markets.
