We assess what a four-day, 32-hour work week would cost Finland’s goods exports across nine large commodity markets. Absent a productivity gain that offsets the lost hours, it would cut export revenue substantially, by about €2.4 billion (-6.4%) over the sample period. In capital-intensive industries the cost increase could, at worst, push the least profitable producers out of the market. As a benchmark, we also assess the effects of Finland’s 2017–2019 Competitiveness Pact (kiky), which raised export revenue in these markets by about €239 million (+0.6%). The Sipilä government’s original, more ambitious package would have raised it even further, by roughly €442 million (+1.2%).
