A critical element of economic performance from antiquity to the present

This volume studies information as an economic resource in the Roman World. Information asymmetry is a distinguishing phenomenon of any human relationship. From an economic perspective, private or hidden information, opposed to publicly observable information, generates advantages and inequalities; at the same time, it is a source of profit, legal and illegal, and of transaction costs. The contributions that make up the present book aim to deepen our understanding of the economy of Ancient Rome by identifying and analysing formal and informal systems of knowledge and institutions that contributed to control, manage, restrict and enhance information. The chapters scrutinize the impact of information asymmetries on specific economic sectors, such as the labour market and the market of real estate, as well as the world of professional associations and trading networks. It further discusses structures and institutions that facilitated and regulated economic information in the public and the private spheres, such as market places, auctions, financial mechanisms and instruments, state treasures and archives. Managing Asymmetric Information in the Roman Economy invites the reader to evaluate economic activities within a larger collective mental, social, and political framework, and aims ultimately to test the applicability of tools and ideas from theoretical frameworks such as the Economics of Information to ancient and comparative historical research.

In this chapter, I distill some elements of the demand and supply of institutions designed to reduce transaction costs in the ancient world. I some cases, contractual parties could reduce transaction cost by accurately designing contracts. In other cases, the failure of private coordination placed the state in a better position than private parties in reducing transaction costs. I emphasize two such (by no means exclusive) contexts: cases in which the gains from reducing transaction costs were spread among large numbers of transactions and cases in which contracts have effects for third parties. Identifying a demand for state intervention raises the question whether the state supplied the appropriate institutions. The state supply of institutions to reduce transaction costs in the ancient world varied. A political-economy perspective suggests that differences depend on the extent to which the state internalizes the gains generated from such institutions.

The economy of the ancient Middle East and Greece is reinterpreted by Morris Silver in this provocative new synthesis. Silver finds that the ancient economy emerges as a class of economies with its own laws of motion shaped by transaction costs (the resources used up in exchanging ownership rights). The analysis of transaction costs provides insights into many characteristics of the ancient economy, such as the important role of the sacred and symbolic gestures in making contracts, magical technology, the entrepreneurial role of high-born women, the elevation of familial ties and other departures from impersonal economics, reliance on slavery and adoption, and the insatiable drive to accumulate trust-capital. The peculiar behavior patterns and mindsets of ancient economic man are shown to be facilitators of economic growth. In recent years, our view of the economy of the ancient world has been shaped by the theories of Karl Polanyi. Silver confronts Polanyi's empirical propositions with the available evidence and demonstrates that antiquity knew active and sophisticated markets. In the course of providing an alternative analytical framework for studying the ancient economy, Silver gives critical attention to the economic views of the Assyriologists I.M. Diakonoff, W.F. Leemans, Mario Liverani, and J.N. Postgate; of the Egyptologists Jacob J. Janssen and Wolfgang Helck; and of the numerous followers of Moses Finley. Silver convincingly demonstrates that the ancient world was not static: periods of pervasive economic regulation by the state are interspersed with lengthy periods of relatively unfettered market activity, and the economies of Sumer, Babylonia, and archaic Greece were capable of transforming themselves in order to take advantage of new opportunities. This new synthesis is essential reading for economic historians and researchers of the ancient Near East and Greece.

Economic Structures of the Ancient Near East (1985) is a political economy of antiquity which applies the universal conclusions of theoretical economics to the interpretation of economic life. The first part of the book shows that the analysis of transaction costs - that is, the resources used up in exchanging ownership rights including costs of communication and of designing and enforcing contracts - provides numerous insights into the structure of the ancient economy. The role of temples as centres of commerce, inculcation of professional standards by gods, elevation of technology to the status of divine gift, religious syncretism and fetishism and many more seemingly exotic practices are comprehended as elements in a strategy to cope with high transaction costs by increasing the stock of what might be called trust capital. It is shown that similar considerations lie behind the ubiquity of diversified, multinational family firms, the prominent entrepreneurial role of high-born women, the prominence within the contractual process of publicly performed conventional gestures and recitations, and the intrusion of gifts, friendship, and other manifestations of personal economics into exchange relationships. The book goes on to examine carefully, and then reject, the view of economic historian Karl Polanyi and others that the ancient Near East lacked true markets for consumer goods and productive factors. The direct evidence of market exchange (local and long distance), occupational specialisation, supply-demand determined prices, investment in material and human capital, production for the market, and other 'modern' traits is uneven with respect to place and time, but nevertheless abundant. The requisite market functions demanded by Polanyi, including a market for labour (slave and free) and elaborate credit and investment markets, can be seen plainly from very early times. Finally, the book deals with the impact on the ancient Near Eastern economy of changes in economic incentives and of changes in economic policy. It becomes evident that ancient economies were capable of making profound alterations in order to take advantage of new economic opportunities. It is also shown that the ancient Near East was not static, as is usually asserted: periods of pervasive economic regulation by the state are interspersed with lengthy periods of relatively unfettered market activity and growth.
