Alfredo Jaar is a politically motivated artist whose work includes installation, photography and film.  Born in Chile and now living in the U.S., Jaar’s socio-critical installations explore global political issues, frequently focusing on the Third World and the relationship between consumption and power.  A 1988 installation in a subway station in New York involved dramatic photographs of impoverished gold miners n Brazil interspersed with quotations of current gold prices, drawing an unexpected parallel between the material desires that motivate people in both poverty-stricken Brazil and affluent Manhattan.
