Horizontal Innovation, Market Power and Growth

I build a generalised model of horizontal product innovation and economic growth taking explicitly into account the most relevant insights stemming from the recent literature on this topic. What results from the analysis is that, when innovation is both deterministic and horizontal, the relationship between market power and aggregate growth is not robust at all. It is also found that not only technology, but also the inter-sectoral competition for the same resource affects growth. This is particularly relevant in terms of public policies aimed at the strategic allocation of skilled workers to the different sectors of the economy.
