  This survey reviews recent developments in revealed preference theory. It
discusses the testable implications of theories of choice that are germane to
specific economic environments. The focus is on expected utility in risky
environments; subjected expected utility and maxmin expected utility in the
presence of uncertainty; and exponentially discounted utility for intertemporal
choice. The testable implications of these theories for data on choice from
classical linear budget sets are described, and shown to follow a common
thread. The theories all imply an inverse relation between prices and
quantities, with different qualifications depending on the functional forms in
the theory under consideration.
