This article examines statutes that limit the liability of landowners who o
pen their property for recreational use. We ask whether landowner immunity
promotes efficient provision by owners and efficient entry by recreational
users. We examine these questions in several contexts, depending on whether
the land is developed or undeveloped, privately or publicly owned, and whe
ther or not the owner charges an entry fee. Our main finding is that, for b
oth privately and publicly owned land, owner immunity is more efficient tha
n owner liability when the land is undeveloped, but this is not true when t
he land is developed.
