Special Episode: Visual Processing in Mice
Wednesday Dec 30, 2020
Wednesday Dec 30, 2020
I discuss the methods and results of my Master's Thesis, in which I analysed electrophysiological data of the mouse visual system using a variety of statistical and computational techniques. I consider some of the major research questions addressed in my work, including population encoding, stimulus representation, neural network modelling, and state space modelling of information transformation. Recommended pre-listening is Episode 113: Visual Processing.

Episode 108: Political Institutions and Sustained Economic Growth
Wednesday Jul 01, 2020
Wednesday Jul 01, 2020
In this sixth and final part in our series on economic growth and development, I discuss in more detail some of the key institutions necessary for economic growth to begin, focusing on property rights, enforcement of contracts, and control of corruption. I review the importance of these institutions in the context of historical case studies of countries ranging from the Soviet Union to Mexico, and outline how the most critical institutions vary with the level of development, giving rise to a middle income trap. I also discuss the Washington Consensus and critically analyse the arguments of critics that such institutional reform is not essential for growth. I conclude with a summary of all we have learned and discussed throughout the growth series. The recommended pre-listening is Episode 107: Economic Growth and Development Part V.

Episode 107: Cultural, Geographic, and Political Explanations of Poverty
Monday Jun 15, 2020
Monday Jun 15, 2020
In this fifth part of our series on economic growth and development, I examine the major factors that have been advanced as explaining differences in growth outcomes between countries. I provide a summary of the arguments and evidence for and against the importance of culture, dependency, democracy, geography, education, and institutions in accounting for differential growth outcomes, and conclude with a comparative empirical analysis in which I argue that institutional differences explain the majority of growth differences. The Recommended pre-listening is Episode 106: Economic Growth and Development Part IV.

Episode 106: Theories of Economic Growth and Development
Sunday May 31, 2020
Sunday May 31, 2020
In this fourth part of our series on economic growth and development, I outline the major theories of economic development developed over the past sixty years. I trace the development of such theories beginning with the Harrod-Domar theory, and proceeding through the Solow-Swan model, the Ramsey model, Romer's spillovers model, and endogenous growth theory, in each case discussing their key features, and analysing their strengths and weaknesses. The episode concludes with a brief survey of a range of more recent growth models focusing on modelling coordination failures and poverty traps, emphasising the work of Daron Acemoglu on economic institutions. The Recommended pre-listening is Episode 105: Economic Growth and Development Part III.

Special Episode: Mario Livio on Galileo
Saturday May 16, 2020
Saturday May 16, 2020
Astrophysicist Mario Livio joins me to discuss his latest book 'Galileo and the Science Deniers', which chronicles the scientific discoveries of Galileo Galilei and how his advocacy of the heliocentric theory led him into confrontation with the Pope. Our conversation covers the significance of Galileo's discovers, the strengths and weaknesses of his case for the heliocentric theory, his role in establishing the modern scientific method, and what we can learn from this episode in history about the importance of intellectual freedom and science communication in the present day.
