Book excerpt: Did a Roman imperial economy exist under the Late Republic, the Roman Principate and the Later Roman Empire? And if so, what type of economy was it? Another equally important question is: did the Roman Empire, by specific actions, the creation of infrastructures, or its very existence, trigger a transformation of economic life in the regions which it dominated? Or was the Empire a marginal affair in the regions that belonged to it, and did economic developments take their own course, independently of the Empire? Questions like these, which are of great consequence to any student of Roman history, archaeology, and Roman law, are treated in this volume, which in its successive parts focuses on: 1. The character of the Roman economy. 2. Economic life in particular regions of the Roman Empire. 3. The economy of the Later Roman Empire.
