The importance of knowledge spillovers for achieving innovation and economic growth is widely recognized. It is not straightforward which type of spillovers is most effective: intra-sectoral spillovers or inter-sectoral spillovers. We investigate this controversy using a model of regional...

We theoretically study the impact of two innovation policies on economic growth in a region that is creative in the sense of Richard Florida and that uses digital technologies to produce a final consumption good. The use of these digital technologies in our creative region gives rise to...

We develop an endogenous growth model which is focussed on entrepreneurial skills and their impact on growth and convergence. Our work is closely related to the model by Acemoglu et al. (2006) but extends their analysis in some important respects. Entrepreneurs in our model dispose of two...

Mainstream endogenous growth models assume that new knowledge is embodied into new intermediate or final goods, monopolistically supplied by the patent holder. Recent technological progress, however, often gives rise to pure intellectual contents, such as software codes or business models,...

This paper constructs a two-sector unified growth model. Learning-by-doing in agriculture eventually allows the preindustrial economy to leave its Malthusian trap. But entrepreneurs in the manufacturing sector do not attempt invention if not much is known about natural phenomena. This delays the...

This paper constructs a two-sector unified growth model that explains the timing and the inevitability of an industrial revolution through entrepreneurs’ role for the accumulation of useful knowledge. While learning-by-doing in agriculture eventually allows the preindustrial economy to leave...

We analyze the impact of obsolescence of economic inventions by incorporating maintenance costsin the endogenous growth model of expanding product varieties. This contrasts with the existingliterature, which ignores maintenance costs and uses the model of quality improvements todescribe...

The present paper takes a geometric approach to characterize the competitive forces behind innovation and dynamic general equilibria determination in the model of growth through creative destruction constructed by Aghion and Howitt (1992). All the essentials can be comprehended intuitively from...

The convergence features of an Endogenous Growth model with Physical capital, Human Capital and R&D have been studied. We add an erosion effect (supported by empirical evidence) to this model, and fully characterize its convergence properties. The dynamics is described by a fourth-order system...
