Raphael Auer's main academic research focuses on international macroeconomics and the micro-foundations of spillovers and external adjustment. He studies how exchange rate movements transmit through currency of invoicing, market structure and global value chains to shape border prices, retail inflation and expenditure switching. Other work has explored how global slack and supply chain integration synchronise inflation across borders. A second strand of his research examines economic and financial stability aspects of digitisation, including digital payments, digital currencies, quantum computing and artificial intelligence.
