Macro & Sectoral Transmission Model
German Industrial Output
Hydrological-to-Macro Transmission: Low water depth restricts barge draft, scaling up the Kleinwasserzuschlag surcharge. Heavy industry cannot fully substitute rail/truck due to rolling stock deficits, idling blast furnaces and chemical output.
