We analyze conceptually and in an empirical counterpart the relationship between economic growth, factor inputs, institutions, and entrepreneurship. In particular, we investigate whether entrepreneurship and institutions, in combination in an ecosystem, can be viewed as a \"missing link\" in an aggregate production function analysis of cross-country differences in economic growth. To do this, we build on the concept of National Systems of Entrepreneurship (NSE) as resource allocation systems that combine institutions and human agency into an interdependent system of complementarities. We explore the empirical relevance of these ideas using data from a representative global survey and institutional sources for 46 countries over the period 2002-2011. We find support for the role of the entrepreneurial ecosystem in economic growth.

A significant gap exists in the conceptualization of entrepreneurship in the digital age. This paper introduces a conceptual framework for studying entrepreneurship in the digital age by integrating two wellestablished concepts: the digital ecosystem and the entrepreneurial ecosystem. The integration of these two ecosystems helps us better understand the interactions of agents and users that incorporate insights of consumers' individual and social behavior. The Digital Entrepreneurial Ecosystem framework consists of four concepts: digital infrastructure governance, digital user citizenship, digital entrepreneurship, and digital marketplace. The paper develops propositions for each of the four concepts and provides a theoretical framework of multisided platforms to better understand the digital entrepreneurial ecosystem. Finally, it outlines a new research agenda to fill the gap in our understanding of entrepreneurship in the digital age.

In its most abstract sense, an ecosystem is a biotic community, encompassing its physical environment, and all the interactions possible in the complex of living and nonliving components. Economics has always been about systems that explain differential output and outcomes. However, economics has generally ignored the role of entrepreneurship in economic systems, just as entrepreneurship studies have laigely overlooked the role of systems in explaining the prevalence and performance of entrepreneurship. The entrepreneurial ecosystem approach has the promise to correct these shortcomings. Its two dominant lineages are the regional development literature and the strategy literature. Both lineages share common roots in ecological systems thinking, providing fresh insights into the interdependence of actors in a particular community to create new value. But studies of both regional development and strategic management have largely ignored the role of entrepreneurs in new value creation. In this paper, we will outline contributions to the entrepreneurial ecosystem approach and conclude with a promising new line of research to our understanding of the emergence, growth, and context of start-ups that have achieved great impact by developing new platforms.

The knowledge spillover theory of entrepreneurship identifies new knowledge as a source of entrepreneurial opportunities, and suggests that entrepreneurs play an important role in commercializing new knowledge developed in large incumbent firms or research institutions. This paper argues that, knowledge spillover entrepreneurship depends not only on new knowledge but more importantly on entrepreneurial absorptive capacity that allows entrepreneurs to understand new knowledge, recognize its value, and commercialize it by creating a firm. This absorptive capacity theory of knowledge spillover entrepreneurship is tested using data based on U.S. metropolitan areas.

According to the knowledge spillover theory of entrepreneurship, the context in which decision-making is derived can influence one's determination to become an entrepreneur. In particular, a context that is rich in knowledge generates entrepreneurial opportunities from those ideas. By commercializing ideas that evolved from an incumbent organization via the creation of a new firm, the entrepreneur (human capital) not only serves as a conduit for the spillover of knowledge, but also for the ensuing innovative activity and enhanced economic performance through resource allocation. The knowledge spillover theory of entrepreneurship brings together contemporary theories and thoughts of entrepreneurship with prevailing theories of economic growth, geography, and strategy and therefore explains not just why some people choose to become an entrepreneur, but also why this matters significantly for the economy and society.

This paper employs Frederick Jackson Turner's Frontier Thesis of American democracy to construct a framework for understanding the U.S. university campus as an entrepreneurial ecosystem. One question that immediately comes to mind when studying ecosystem performance is what the proper unit of analysis is: the country, the state, the city, the region, or something smaller, like an incubator or accelerator? This paper suggests that the open, innovative American frontier that closed at the end of the twentieth century has reemerged in the entrepreneurial economy on the U.S. campus. The contemporary campus entrepreneurial ecosystem offers the characteristics of Turner's frontier available assets, liberty, and diversity while creating opportunity, and fostering entrepreneurship and innovation. A case study of the University of Chicago explores governance of the campus as an entrepreneurial ecosystem and the output produced by that campus ecosystem.

We evaluate how country-level entrepreneurship—measured via the national system of entrepreneurship—triggers total factor productivity (TFP) by increasing the effects of Kirznerian and Schumpeterian entrepreneurship. Using a database for 45 developed and developing countries during 2002–2013, we employ non-parametric techniques to build a world technology frontier and compute TFP estimates. The results of the common factor models reveal that the national system of entrepreneurship is a relevant conduit of TFP, and that this effect is heterogeneous across countries. Policies supporting Kirznerian entrepreneurship—e.g., increased business formation rates—may promote the creation of low value-adding businesses which is not associated with higher TFP rates. Policy interventions targeting Schumpeterian entrepreneurship objectives—e.g., innovative entrepreneurship and the development of new technologies—are conducive to technical change by promoting upward shifts in the countries’ production function and, consequently, productivity growth.

The information technology revolution (ITR) propelled a shift from the industrial age to the digital age. While in the industrial age it was easy to disentangle the distinctions between the city/region and the country based on proximity, in the digital age this is much harder. The digital age is characterized by the rise of multisided platform organizations, their platform-based ecosystem and the digital technology infrastructure. This paper takes an ex post evolutionary perspective and examines the successful firms of the global digital platform economy and the regions that produced them. We explore the question of what cities played the most important role over the past 50 years covering five distinct technologies: semiconductors, the personal computer, the Internet and search engines, smartphones and wireless, and cloud computing and matchmakers. Successful city/regional development requires the management of both the regional entrepreneurial ecosystem and the platform-based ecosystem simultaneously.

This paper is an introduction to the special issue from the 3rd Global Entrepreneurship Monitor Research Conference held in Washington, D.C., in 2008. The paper has three objectives. First, to discuss the importance of the three stages of economic development, the factor-driven stage, the efficiency-driven stage and the innovation-driven stage. Second, to examine the empirical evidence on the relationship between stages of economic development and entrepreneurship. Third, to present a summary of the papers in the context of the theory.

The perhaps broadest approach to economic performance at the level of a country is the concept of national systems of innovation. Despite the emergence of a compelling literature identifying the persistence of innovative activities and country specific institutional effects, evidence on the nature of national systems of innovation is still missing and a number of crucial questions and answers remain unanswered. To shed light on these issues, as of leading scholars of entrepreneurship and innovation was assembled from around the world for a conference on “National Systems of Entrepreneurship and Innovation” at the ZEW Mannheim in November 2014. This article draws on the NSI framework, sets it in a larger context, examines the logic of the approach and introduces the special issue by summarizing the papers presented at the conference and selected for this special issue.
