Markets have evolved into increasingly complex information systems, offering both improved access to information among participants and more control over their actions within the system, with uncertain effects on participant welfare. My project focuses on the optimal design of market information systems, addressing four challenges: i. competition in digital multiproduct ecosystems, ii. procurement of public information systems, iii. development of smarter tax systems, and iv. climate. I introduce fresh frameworks for evaluating consumer steering algorithms used in digital markets, and for studying the procurement and development of public information systems - providing novel tools for authorities. My project also devises new approaches to mitigate the pitfalls of climate talks and ensure a fair distribution of abatement costs. The project is located at the University of Helsinki, with key local collaborations involving competition authorities, and taxation and climate researchers.
