“…like Feil, Clark and Parry (1990:323) suggest that this control over important prestige items may have been critical in the emergence of chiefdoms. Similarly, Brunton (1975), Bishop (1987), and others have argued that both natural access constraints, such as those imposed by long distances, and artificial access constraints, such as control over exchange imposed by aggrandizers, result in increased socioeconomic and political complexity. Lemonnier (199Oa:73) explicitly states that effort investment is the primary criterion for items used in economic competition, while Clark and Parry (1990:297) add that prestige goods in transegalitarian societies not only involve high labor costs to procure or produce but also have conspicuous display characteristics.…”
