Sweden experienced a remarkable economic transformation between the 18th century and the outbreak of World War I. This dissertation consists of four self-contained papers that uses a quantitative empirical approach to identify key drivers of this transformation by analyzing the contribution of the potato to economic growth, the determinants of the early investments in mass schooling, and how the rollout of the national railroad network shaped rural and urban growth patterns from the mid-19th century to the present day. Together, the findings of this dissertation contribute novel evidence on the causal determinants of Sweden’s acceleration in growth and also shed light on the historical roots of contemporary patterns of regional and urban development.
