This paper investigates the demand elasticity of search. We provide a new c
haracterization of monotone hazard rate and of the first-order condition de
termining the optimal reservation price, and prove that the demand for info
rmation is elastic if the hazard rate function h for the distribution of of
fers is decreasing and inelastic if h is increasing. (C) 2000 Elsevier Scie
