Randall Holcombe's book Entrepreneurship and Economic Progress lays a solid foundation for understanding the relationship between entrepreneurship and economic progress. He argues that entrepreneurship, not just increasing inputs, is key to economic progress. There are two types of entrepreneurship: Kirznerian responds to disequilibrium, while Schumpeterian creates disequilibrium. Future generations will be grateful for Holcombe's work clarifying economic progress and highlighting different types of entrepreneurship. The book has important implications for economic theory and policy by emphasizing the role of entrepreneurship over increasing inputs alone.
