The firm maintains confidential interview relationships with
57 leading participants in the art trade. At least once every two years, and more
frequently if needed, staff economists conduct candid, face-to-face interviews with
dealers, auctioneers, and others in principal centers of the art trade.
This ongoing process ensures that the views of actual market participants fully
inform the various research processes and initiatives. The observations, concerns,
and operating results of substantial participants in the trade are central to the
updating of polling instruments used by the firm, to the formation of solid working
assumptions, and to achieving an effective degree of analytic observation and
objectivity.
