early economic thinkers and classic works such as Cantillon (1755), Knight (1921), and Kirzner (1973). The paper opens by explaining how uncertainty and thus entrepreneurship disappeared from microeconomic theory as it became increasingly formalized (and stylized). It then goes on to bring the entrepreneur and entrepreneurial decision-making back into economic theory by focusing on the interrelationships among actors, knowledge, and perceived economic opportunities using a resource-based framework. The third paper in this section (Chapter 4) is by Foss and Klein, "Entrepreneurship and the Economic Theory of the Firm: Any Gains from Trade?" Foss and Klein strongly link theories of the firm to entrepreneurship, arguing a fundamental and intrinsic connection between the two. They, like Mahoney and Michael, explain how entrepreneurship became less important in economic models as the general equilibrium model became dominant. Foss and Klein ask: Does the entrepreneur need a firm? They focus on the judgment of the entrepreneur and suggest that this judgment is exercised through asset ownership and starting a firm. Foss and Klein further argue that it is through this notion of judgment that heterogeneous assets combine to meet future wants.

As we move into the 21st century, the world seems a smaller place - transportation costs continue to fall, fiber optic networks speed information around the planet, and corporations operate on a global scale. One might reasonably ask whether location really matters anymore. Despite these trends - perhaps because of them - the last few years have witnessed a rapid rise in interest in "place" and "space" across the social sciences. While the importance of distance declines, strategic interest in location appears greater than ever. This volume draws together researchers from a variety of disciplines - economics, geography, marketing, organizational behavior, sociology, and urban planning - working at the forefront of this wave to explore some of the important ways in which location matters for firms in the 21st century.
