The organization’s primary goal is to provide market solutions to environmental problems. PERC pioneered the approach known as free market environmentalism and conducts research in the areas of water, forestry, public lands, and endangered species, among others. Free market environmentalism is based on several tenets: Private property rights encourage stewardship of resources; government subsidies often degrade the environment; market incentives encourage individuals to protect environmental quality; and polluters should be liable for the harm they cause others. ○○○○○ PERC —T HE CENTER FOR FREE MARKET ENVIRONMENTALISM— 502 SOUTH 19TH AVENUE, SUITE 211 BOZEMAN, MONTANA 59718-6827 PHONE: 406-587-9591 FAX: 406-586-7555 www.perc.org [email protected] CONTENTS ○○○○○○○○○ INTRODUCTION AND BACKGROUND ○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○ 1 LESSON 1 “All the Fish in the Sea” ○ ○ ○ ○○○○○○○○○○○○○○○○○○ 9 LESSON 2 PREPARATION Solving Economic Mysteries ○○○○○○○○○○○○○○○○○○○ 23 MYSTERY 1 Do You Always Hurt the One You Love? ○○○○○○○○○○○ 27 MYSTERY 2 If We’re So Smart . ? ○ ○ ○ ○ ○ ○ ○ ○ ○ ○○○○○○○○○○○○○ 35 MYSTERY 3 Old MacDonald Had a (Fish?!)
