The Palaiologoi tried to revive the economy, and re-establish traditional forms of political supervision, and guidance of the economy. It was, however, apparent that the late Byzantine state was unable to gain full control of either the foreign or domestic economic forces. Gradually, the state lost its influence on the modalities of trade and the price mechanisms, and its control over the outflow of precious metals and, according to some scholars, even over the minting of coins. Late Byzantine officials supposed to implement a regulatory policy used the state prerogatives placed into their hands to pursue their private businesses. Private commercial activity was also affected by the crises in foreign policy, and the internal erosion of Byzantium.
