Understanding the economic role of national infrastructure systems

Academic Profile

My research consists of looking at infrastructure and how it economically impacts households and firms, and thus by extension what role infrastructure can play in different endogenous growth theories. My focus is on infrastructure systems in developed countries in general with a special focus on applying these models to the UK in particular.

The reason why I find this research fascinating is due to the increasing need for infrastructure investments required in the future. As our current infrastructure assets age and we need adapt society to become more sustainable, we will have to invest in new infrastructure. Thus it is vital to understand the consequences of these investments on a macroeconomic level. Currently, very few economic growth models take infrastructure into account at all, meaning that the debate surrounding the economic impact of infrastructure investments has not been resolved. The normal treatment of infrastructure capital is to include it within the traditional notion of capital, something that is unsatisfactory as infrastructure systems are networks and thus subject to network externalities and different economies of scale to that of other capital assets.

My background is in physics with a BSc from Imperial College London and an MSt from Cambridge. While doing my undergraduate degree I focused mainly on climate science and atmospheric physics as well as doing courses on environmental physics. By the end of my fourth year I wanted to apply my mathematical and quantitative science skills on something that lay closer to people's day to day lives and so I became interested in doing research about infrastructure.
