Although GDP growth in the Netherlands has recently been stronger than in peer countries, the main contributor has been the growth in labor. If GDP is divided by labor, productivity growth appears to have been slower than in peers. This chapter discusses both exogenous and endogenous factors behind the disappointing productivity growth in the Netherlands and derives policy implications.

This paper studies the impact of localization, urbanization, and diversification on regional labor productivity levels and growth. We find substantial effects, accounting for roughly half of the explained variation in the labor productivity differences within the Netherlands in the 1990s. Diversification, urbanization, and localization effects are significant and positive for productivity levels. These levels appear cointegrated. The error correction specification of productivity growth surprisingly reflects negative agglomeration effects. From the theoretical model it follows that congestion effects must have taken precedence over agglomeration effects during this period. Both agglomeration and congestion effects are dampened by job density in neighboring regions. Finally, policy simulations with the estimated model show that spatial concentration is more harmful to national productivity growth than spatial dispersion.

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.
