Abstract/Index

The process aimed at discovering new ideas is an economic activity whose returns are intrinsically uncertain. In a standard neo-Schumpeterian growth framework we assume that, when deciding upon R&D efforts, economic agents hold ‘ambiguous beliefs’ about the exact probability of arrival of the next vertical innovations, and face ambiguity via the α-MEU decision rule (Ghirardato et al. (2004)). Along the steady-state equilibrium the higher the agents’ ambiguity aversion (α), the lower the R&D efforts and, coeteris paribus, the overall economic performance. Consistently with a cross-country empirical evidence, this causal mechanism suggests that, together with the profitability conditions of the economy, different ‘cultural’ attitudes towards ambiguity may contribute to explain the different R&D intensities observed across countries.
