Løken and Alexander Willén August 04, 2025 Abstract: We examine the welfare consequences of reallocating high-skilled labor across national borders. A labor demand shock in Norway—driven by a surge in oil prices—substantially increased physician wages and sharply raised the incentive for Swedish doctors to commute across the border. Leveraging linked administrative data across the two countries and a difference-in-differences design, we show that this shift doubled commuting rates and significantly reduced Sweden’s domestic physician supply. The result was a persistent rise in mortality in Sweden, with no corresponding health gains in Norway. These effects were unevenly distributed, disproportionately harming certain places and populations. The underlying mechanism was a severe strain on Sweden’s healthcare system: shortages of high-skilled generalists led to more hospitalizations, premature discharges and higher readmission rates. Mortality effects were larger in low-density physician regions and concentrated in older individuals and acute conditions.
