The conquest of Egypt and Asia, leading to new urban and fiscal infrastructures and new forms and levels of elite consumption, increased the scale of trade and exchange in the Hellenistic economy. Complex institutional changes that were spurred by both fiscal-military demand and local responses to this demand changed agrarian and commercial patterns, with likely positive effects on local markets. This chapter argues that the Hellenistic period was one of moderate economic growth both in the Greek poleis of the Aegean and in the core regions of Hellenistic Asia and Egypt. The greater presence of Roman traders in the Hellenistic East from the second century onwards is also likely to have had positive effects on market exchange and monetary circulation. Yet there is reason to assume that in the final decades of the Hellenistic period, all Hellenistic regions to some extent, but particularly the Aegean and Asia Minor, suffered from the destructive forces of the Roman military presence and subsequent tributary exploitation. Only after the Roman civil wars came to an end and fiscal practices were better regulated did the economies of the East begin to recover and to expand along the pathways that had developed in the Hellenistic period.

This chapter discusses the economic developments occurring within the Ptolemaic empire (323–30 BCE), of which Egypt was the core province. It explores how state formation affected economic development and how Ptolemaic imperialism, demography, and the interaction between Egyptian and Greek social networks were factors of economic change and economic exploitation. After an overview of past and current approaches to the economy of the Ptolemaic empire and of the geography of the empire, it assesses the cost and benefits of military conquests and the management of migrations patterns and new settlements by the Ptolemies, who increased their revenues and reduced the cost of their army through land allotments to cleruchs. The political economy of the Ptolemies relied on a complex tax system, with some documents pointing to a centralized taxation of the provinces, and innovative but also unusual monetary policies, such as closed-currency system based on a lower weight standard than the Attic standard in Egypt, Cyprus, and Syria-Phoenicia. The chapter concludes with examples of the synergistic relationship between empire, warfare, and trade and between the public and private spheres of the economy, and sketches the purchasing power of different economic groups in Egypt.
