Fundamentally, Roman economic history is the study of how and why inhabitants of the Roman world produced, distributed and exchanged goods and services. By understanding the economic actions, events, institutions and products of the Roman world, Roman economic historians come to understand better the Romans themselves: their motivations, values, relationships and identities, among other things. With such a broad remit, today's Roman economic and monetary historians not only scour traditional sources for evidence of Roman commerce, prices, labour, capital and contracts, (...) but they now deploy an ever-broadening range of methodologies, theories and approaches – some of which originate well outside the disciplines of both history and economics. Some Roman economic historians, for example, create, investigate and run simulations, using massive digital archives of data gleaned from ancient evidence. Others compare micro-nutrients in ancient wheat varieties with their modern counterparts to gain a better understanding of diet, nutrition and economic prosperity in Roman cities. Increasingly, specialists in some aspect of the Roman economy find themselves members of internationally funded interdisciplinary teams seeking to understand what Arctic ice cores or North-American tree rings say about money production in the Roman principate. Roman economic historians’ scholarly sprawl has never been more challenging to describe, but I believe it is possible to group recent developments in the field into three overlapping areas: digitisation, particularisation and consilience.
