The importance of entrepreneurship for achieving economic growth in contemporary economies is widely recognized, both by policy makers and economists. It is deeply embedded in the current European policy approach that the creativity and independence of entrepreneurs contribute to higher levels of economic activity. Indeed, according to the European Commission (2003, p. 9), "The challenge for the European Union is to identify the key factors for building a climate in which entrepreneurial initiative and business activities can thrive. Policy measures should seek to boost the Union's levels of entrepreneurship, adopting the most appropriate approach for producing more entrepreneurs and for getting more firms to grow. " Audretsch (2003, p. 5) states that "Entrepreneurship has become the engine of economic and social development throughout the world. " The relation between entrepreneurship and economic growth is embedded in several strands of the economic literature. A first strand of literature involves the general understanding of the role of entrepreneurship in the modern economy. Seminal contributions were made by Schumpeter (1934), Knight (1921) and Kirzner (1973). These economists stress different aspects of the role of the entrepreneur. While Schumpeter stresses the innovating aspect, Knight stresses the risk assuming aspect. Kirzner, finally, stresses the role of the entrepreneur in leading markets to equilibrium. Acs (1992) discusses the contribution of small firms in modern economies.

By serving as a conduit for knowledge spillovers, entrepreneurship is the missing link between investments in new knowledge and economic growth. The knowledge spillover theory of entrepreneurship provides not just an explanation of why entrepreneurship has become more prevalent as the factor of knowledge has emerged as a crucial source for comparative advantage, but also why entrepreneurship plays a vital role in generating economic growth. Entrepreneurship is an important mechanism permeating the knowledge filter to facilitate the spill over of knowledge and ultimately generate economic growth.

The Relationship between Entrepreneurship and Economic Development summarizes and updates the empirical evidence and presents the main lines of reasoning behind the relationship between economic development and entrepreneurship.

Leading international scholars provide a timely reconsideration of how and why entrepreneurship matters for economic development, particularly in emerging and developing economies. The book critically dissects the evolving relationship between entrepreneurs and the state.

Higher employment, economic growth and innovation are fundamental objectives of modern economies. One effective means of attaining these goals is the development of successful entrepreneurs, and this book aims to provide a deeper, research-based understanding of the factors influencing successful entrepreneurship. Mirjam van Praag compares and contrasts the economic theory of entrepreneurship with determinants of successful entrepreneurship derived from empirical evidence, in an attempt to discover what makes for an accomplished entrepreneur. The author's state-of-the-art historical, theoretical and empirical research on successful entrepreneurship - all from a explicit economic perspective - comprehensively addresses questions such as: 'What are the factors that influence individuals' decisions to start a business venture as opposed to working as an employee?' and 'What are the individual characteristics that make one successful as an entrepreneur?' thereby supporting or dispelling various existing myths. Individual factors contributing to the success of entrepreneurs that are considered include, amongst others, human capital, financial capital and psychological traits. The importance of such factors for the various phases of entrepreneurship, including start-up, delivery and performance is also measured.

The spillovers in knowledge among largely college-educated workers were among the key reasons for the impressive degree of economic growth and spread of entrepreneurship in the United States during the 1990s. Prior 'industrial policies' in the 1970s and 1980s did not advance growth because these were based on outmoded large manufacturing models. Zoltan Acs and Catherine Armington use a knowledge spillover theory of entrepreneurship to explain new firm formation rates in regional economies during the 1990s period and beyond. The fastest-growing regions are those that have the highest rates of new firm formation, and which are not dominated by large businesses. The authors of this text also find support for the thesis that knowledge spillovers move across industries and are not confined within a single industry. As a result, they suggest, regional policies to encourage and sustain growth should focus on entrepreneurship among other factors.
