S7 Ep32: Will tax or finance get us to net zero?

If we’re going to get to net zero in time, economists argue that carbon taxation alone is the best policy. But less than a quarter of emissions are subject to any carbon pricing. And even then, the price of carbon is far too low. So how much climate finance will it take to fill that gap to get us to a socially optimal solution? Lasse Heje Pedersen talks to Alissa and Tim about how he estimates the rate of exchange between the cost of capital and a carbon tax, and what that implies for policy.

The first in a series of VoxTalks Economics based on some of the most interesting presentations from the PSE-CEPR Policy Forum 2024. Imagine that one day, you are offered the chance to move to a new, better, bigger house in the same city as you live, with the government paying for 90% of your mortgage. This is what happens in Brazil, where millions of people have been given access to better housing. But how big is this prize really? Gabriel Ulyssea tells Tim Phillips how many of the beneficiaries discovered that location matters most in real estate.

If we want to help millions of working people who have high-polluting jobs to find news work during the green transition, first we need to know more about what they do and where they are. Orsetta Causa tells Tim Phillips about the location of dirty jobs, and whether policy to reskill workers can finally succeed. 

If the climate crosses any of a number of tipping points, what are the implications for climate finance? Tipping points are large, probably irreversible, changes in nature that may occur as a result of the increase in global temperature. Worse, crossing one tipping point may cause a cascade of others. Alissa and Tim’s talk to Tim Lenton, one of the authors of the Global Tipping Points Report, and Patrick Bolton to discuss how Climate Finance struggles to price the risk of tipping points.

The #MeToo movement inspired many professions, and the men who work in those professions, to reflect on whether female colleagues were treated fairly. Economics had its own highly visible, and sometimes controversial, #MeToo moment. What has been the impact of #MeToo on patterns of co-authorship? Noriko Amano-Patino, Elisa Faraglia and Chryssi Giannitsarou deliver good and bad news to Tim Phillips. 

Which firms are infiltrated by organised crime, and why? We know that organised crime has links to some firms in the legal economy. But how big is this infiltration, and what do they gain from it? Rocco Macchiavello tells Tim Phillips about which firms are infiltrated, how this occurs – and what the crime families have to gain.

Next week, there will be EU elections across Europe. Later this year, there is a closely fought election in the US. As traditional political right-left allegiances break down, what is influencing the way we vote? Andrés Rodríguez-Pose tells Tim Phillips how economic stagnation combined with increased interpersonal and regional inequality has been driving the populist vote.

We are increasingly aware of the number of people who secretly suffer from depression. Many sufferers are reluctant to seek help because they fear that others will assume they are weak or lazy. If depressed people discover that most of their peers feel sympathy rather than contempt for them, will they be empowered to seek help? Egon Tripodi and his colleagues tested that assumption. He tells Tim Phillips what they discovered.

Fake news threatens our electoral process and our social structure. Fabrice Collard tells Tim Phillips that it threatens economic stability too, and that the impact of the of the fake news epidemic can be detected as a rise in uncertainty that transmits to core economic statistics. 

If economics and finance are the key to creating a sustainable way to live, what is the role of business schools in training the people who will make that happen? Alissa and Tim talk to Peter Tufano of Harvard Business about how they should be taking the lead in teaching the tools of climate finance. They also discuss his research into what the public thinks the role of business in society should be – and how that has diverged from what business schools teach.
