Vietnam, a lower-middle-income economy, faces severe climate risks from heat waves, sea-level rise, and tropical cyclones, which are expected to intensify under ongoing global warming. Using a dynamic general equilibrium model, we analyze economic transition dynamics from 2015 to 2100, incorporating heat-induced labor productivity losses, agricultural land loss, and cyclone-related property damage. We compare a Paris-compatible scenario limiting warming to below 2 °C with a high-emission scenario reaching 4–5 °C. While output and investment impacts remain highly uncertain and statistically indistinguishable across scenarios until 2100, consumption losses are significantly larger under high emissions, mainly driven by heat-related productivity declines, with cyclones contributing most to uncertainty. These findings underscore the importance of considering multiple impact channels beyond output damages in climate-development research.

We exploit an information shock related to the German Supply Chain Due Diligence Act and use detailed customs data to analyze how smaller, non-listed firms respond when expecting accountability for externalities beyond their organizational boundaries. Product-level regressions reveal a substantial reduction in imports from high ESG-risk production sectors. Adjustments occur mainly at the extensive margin, indicating that firms cut ties with high-risk suppliers. The product-level results translate into meaningful changes in overall international procurement for firms with Big Four auditors. Our findings suggest potential limits to mandates requiring firms to integrate broad sustainability considerations into operational decisions.

Trotz der Handelskonflikte zeigt sich die Weltwirtschaft bislang robust und dürfte weiter in mäßigem Tempo expandieren. Die Weltproduktion steigt im Jahr 2025 um 2,6% und im Jahr darauf um 2,4%. Ob sich die deutsche Wirtschaft auf Erholungskurs befindet, ist weiterhin nicht erkennbar, zumal sie in der zweiten Jahreshälfte den Dämpfer höherer US-Zölle zu verkraften hat. Erst für 2026 stehen die Chancen gut, dass finanzpolitische Impulse zusammen mit niedrigen Leitzinsen eine konjunkturelle Belebung bewirken. Das Bruttoinlandsprodukt dürfte dann um 0,8% zunehmen, nach 0,2% im Jahr 2025.
