In today’s rapidly changing economic climate, understanding the detailed flow of money through the economy is crucial. This research stream leverages extensive financial micro-data to enhance how economic indicators like GDP and inflation are understood and utilised. By disaggregating these traditionally national statistics, we can trace economic interactions at different levels of granularity, for example between different sectors and regions—revealing novel insights into their evolution. We believe this approach not only improves the accuracy of economic metrics but also enriches our understanding of economic relationships and trends, enabling better-informed decisions at all levels of business and governance.
