Tiago Santos joins Tobi on this episode of the podcast to discuss Parliamentarianism. Tiago believes that if African countries had adopted parliamentary systems during their democratization wave, they would have likely seen better development outcomes, citing the success of Botswana and the economic growth seen in parliamentary countries. He also highlights four main flaws in presidential systems according to political scientist Juan Linz: lack of clarity in authority, rigidity, winner-takes-all nature, and personalism. These issues often lead to ineffective governance, coups, and excessive polarization, which hinder development and political stability. Tiago further argues that better governance structures, like those provided by parliamentary systems, are crucial for economic development. He emphasizes that parliamentary systems lead to greater political stability and more inclusive decision-making, essential for fostering long-term growth and escaping the "Malthusian Trap."

Tobi;

You're, I would say, a strong advocate of parliamentarianism. I wouldn't call myself a strong advocate, but I'm fairly biased towards your point of view and became even more convinced when I read your book. Particularly in Africa, a couple of countries went through long periods of military dictatorship. And around 20, 25 years ago, there came another wave of widespread democratisation on the continent. What happened was, maybe due to the influence of American foreign policy or some other global forces, a lot of these countries opted for the American-style presidential system. And in my own observation, maybe I'm wrong empirically, a lot of these countries, my country, Nigeria included, struggled with the workings of this presidential system, such that there had been constant agitation for a kind of return to the parliamentary system that Nigeria had immediately after independence. My question to you then is that, are you willing to say or assert that perhaps if a bunch of these countries around 20, 25 years ago had opted for parliamentary system, would they have done better development-wise?

Tiago;

I don't think anybody can say for sure, but I'm convinced that they would probably, very likely, had done better. With respect to Africa, I think, yes, there is a strong influence from the American model because it's obviously a very successful country. So it's very easy to model after them. But I think that there is something else also in the choice of presidentialism by African countries. I've read a paper by James Robinson and Ragnar Torvik that argues that there is a tendency for endogenous presidentialism, which is that exactly because in presidentialism the leader has more chances to exert their powers without much resistance. So back in the 60s, a bunch of countries in Africa, I think most of them, had a parliamentary constitution, not only Nigeria, but many other countries had a parliamentary constitution and basically all of them switched to presidentialism at some point. If you look at Botswana, the economic performance that they had since the 1960s is very impressive. I wish Brazil had the rate of growth that Botswana has been experiencing consistently. So looking at the countries in Africa that have adopted parliamentary constitution, I think that it would be the case, yes, that had these countries adopted a parliamentary constitution back when they democratised again, they would probably have done better.

Tobi;

I mean, Nigeria is so loud. that the word restructuring, which is a shorthand for reconstituting the political system, is so common in political parlance and, you know, we kept shouting restructuring, restructuring, and it never really comes to pass.

But given the ubiquity and the allure of presidentialism, at what point, particularly historically, did you become convinced enough to write this book about the superiority of parliamentary systems?

Tiago;

It wasn't something that particularly interested me during the first 40 years of my life, before writing the book. So I wrote a book on the economic effects of the Brazilian Constitution. So the idea was to make this research and check every article of the Constitution, what economic effects we could expect to have in Brazil with my then boss, Otaviano Canuto, in the Brazilian constituency in the Board of Directors of the World Bank. And one of the things that I started researching on was exactly the difference between presidentialism and parliamentarianism. And I started to find some striking results. This was too big to go into the article, so we don't mention it in the article that we published. We mentioned other aspects of the Brazilian constitution, but then I couldn't stop researching this. And I was always also checking myself, trying to push my good economist friends. I was trying to also get comments from many people that have thought about this problem very well and to check that I wasn't thinking something that was completely out of base. And I was increasingly convinced because of the feedback that I got, the continuation of my research, it was then when I combined all the elements that I think are in favour of parliamentarianism that if we just look at countries that are parliamentary or countries that are presidential, you see that parliamentary countries perform better in just about any indicator.

If you look at the history, if you look at the informal theory, if you look at formal theory from economics, if you look at the evidence that people try to do with studies that are not just correlational, but that introduced good statistical controls for things, If you look at complementary evidence from companies - so companies can adopt a parliamentary model, which is having a board of directors and this board of directors can control the CEO. And no company elects a CEO by the shareholders directly. And this CEO will have a checks and balances relationship with the board of directors. This figure doesn't exist. And I think the market is in a very good position to choose the best arrangement. And finally, the council management system in the U.S. that I learned when I was doing this research is a system that is very similar to parliamentarianism. And cities that adopt the council management system perform much better than cities that adopt a strong mayor system, which is similar to the presidential system.

Tobi;

So what are the key flaws that you mention in the book? Perhaps there's more now since you wrote the book. What are the key flaws in presidentialism that you think a parliamentary system addresses effectively?

Tiago;

We were discussing before you started recording. I don't try to be original in my book. I try only to convey the knowledge that's already there. And in this, the most influential thinker is by far Juan Linz, a political scientist. And I think that he has the best frame for this. And he talks about four main flaws in presidentialism that parliamentarians doesn't suffer from. So these flaws are in presidential countries, you don't have a clarity of where the authority lies. So what happens in the end is if you like the policy that Congress is trying to push, then you will stand on the side of Congress and if you like the policy that the president is trying to push, then you will stand on the side of the president. And there will be lots of undermining of initiatives by both the Congress and the president. They won't agree on many things and it will be difficult to have a coherent proposal. Daniel Diermeier has an article on this, on how parliamentary systems are more cohesive.

So the second thing I think is a big problem, also from Juan Linz, is the rigidity. So if a country is presidential and the president is working badly, there's nothing we can do. We just have to wait for the mandate to end. And if this is bad enough, if some sectors of society perceive this to be bad enough, you have often coups that derive from a perception that there's no way that the president can stay in place. And then a majority of the powerful actors in a society will install a coup. So that's why the prominence to coups in presidentialism is so much greater than in parliamentarianism.

Then you have a winner-take-all situation. So if you win the presidency, you have so much power that you will be able to implement so many things and you have almost complete control over so much of government. Whereas if you are the losing side of a presidential election, then you are out of government completely. So there's too much at stake. And this incentivises the kind of polarisation that we see in many presidential countries, a type of politics that is very visceral, that is very combative. That's not the kind of politics that we would hope for. And lastly, it's personalism. The presidential system focuses way too much on the figure of one person instead of different institutions in society, different sectors and different voices. And it's often the case that in many presidential countries, people don't love the candidate that they see. They would...
