The ‘liberty’ of one is his permission to act as he pleases, supported against interference by the power of the concern or government - John R. Commons

The difficulty in defining a field for the so-called institutional economics is the uncertainty of meaning of an institution. Sometimes an institution seems to mean a framework of laws or natural rights within which individuals act like inmates. Sometimes it seems to mean the behavior of the inmates themselves. Sometimes anything additional to or critical of the classical or hedonic economics is deemed to be institutional. Sometimes anything that is "economic behavior" is institutional. Sometimes anything that is "dynamic" instead of "static," or a "process" instead of commodities, or activity instead of feelings, or mass action instead of individual action, or management instead of equilibrium, or control instead of laissez faire, seems to be institutional economics.

The concept of property itself had come up out of the common law and carried with it the idea of a natural, or common-law rights of liberty to acquire, use and dispose of physical things.

The aim of this volume is to work out an evolutionary and behavioristic, or rather volitional, theory of value. It was commenced thirty-five years ago at Johns Hopkins University under my stimulating teacher, Richard T. Ely.
