This timely book argues that the overcrowding of national parks in the United States represents a social problem in need of public sector action and a policy solution, as no systematic means to address this problem has been implemented either nationally or on a park-by-park basis. Throughout the book, Albert N. Link provides an innovative pricing solution to the overcrowding of the parks which will help to change the existing status quo. Utilizing a methodology grounded in economics, and expanding the use and policy relevance of the concept of public sector entrepreneurship, the author illustrates how individuals respond to prices and offers a method to estimate the impact of a seasonal entrance fee based on calculated price elasticities of demand. Chapters also provide recommendations for increases in seasonal entrance fees individually for each of the national parks that currently have an entrance fee.Public Sector Entrepreneurship will be a key resource for academics and students in the fields of entrepreneurship, public management and resource management who are looking to use economics as a framework for analyzing tourism topics, as well as environmental researchers and public policy officials responsible for national parks.
