In a rapidly changing market, who defines the value of art? How can collectors navigate an industry that is increasingly complex in terms of geography and channels of distribution?

During Dallas Art Fair weekend, a panel of major art world players with divergent perspectives on the buying and selling of art - collector and dealer Stefan Simchowitz, art advisor Amy Cappellazzo, and curator Paul Schimmel, co-founder of Hauser Wirth & Schimmel in Los Angeles - will discuss the shifting hierarchies and new structures that are changing the way culture is thought about and marketed. The conversation will be moderated by art sociologist, journalist and author, Sarah Thornton.
