Economics for the Common Good summary

Introduction: What Is in It for Me?

Economics for the Common Good by Jean Tirole What is in it for me? Delve into economics with a Nobel Prize winner. It is sometimes called the dismal science, but the weird and wonderful world of economics is anything but drab. As a clear-eyed observer of the world, Nobel Prize-winning French economist Jean Tirole can draw upon decades of economic expertise to illuminate common features of the world in a surprising and often counterintuitive light between demonstrating why an anti-poaching NGO should sell confiscated ivory tusks rather than destroy them and explaining the debt crisis in Southern Europe.

Tirole takes a look at the big topics that shape our present and will determine our future. Why do we need finance markets? Even after speculators demonstrated their recklessness in the 2008 financial crash. What stops us from tackling the looming threat of drastic climate change, despite the repeated warnings of scientists, and how can the state and free markets best be brought together to guarantee growth, innovation, and the common good?

These are just some of the burning questions. This summary will take on. You will also find out what makes the tragedy of the commons so tragic, what economists can learn from their colleagues in the humanities, and how the 2008 financial crisis started with dodgy mortgages. This is economics for the Common Good by Jean Tirole.

Chapter 1: Our Understanding of How the Economy Works Is Shaped by Confirmation Biases

Our understanding of how the economy works is shaped by confirmation biases. The way we see the world is shaped by our beliefs. We emphasize facts that confirm ideas we already hold, which is why we read newspapers that echo our own political views and seek out like-minded friends. Economics is no different, our pre-existing beliefs mold our attitudes toward the facts.

This means we often do not make the wisest economic decisions. Instead of looking at the evidence and making decisions accordingly, we look for simple rules that we can apply to every new situation. This approach can lead us astray because economics can be deeply counterintuitive. Imagine an environmental NGO that campaigns against poaching.

It has just managed to intercept a consignment of ivory tusks being shipped by a group of poachers who kill endangered elephants. What should it do with the confiscated ivory? Moral intuition tells us that the trade in illegal ivory is reprehensible, which means we should destroy it, right? Here, Jean Tirole would point out that we face a clash of two different goals upholding moral standards and protecting elephants from poachers.

Solution A, destroying the ivory, satisfies our moral intuition, but it sacrifices the practical means to protect elephants since it raises no funds and keeps ivory scarce, leaving poachers with high incentives. Solution B, selling the ivory, raises the needed funds for the environmental organization and depresses market prices, reducing poachers' incentives. Yet, this solution sacrifices moral clarity and could stimulate demand by signaling to buyers that owning ivory is fine. It could also allow poachers to launder illegal ivory through legal channels unless strong governance is in place.

This is classic economic reasoning where we must balance competing goals and trade-offs rather than looking for simple black and white answers. As you can see, taking a long-term perspective of the kind offered by economics changes the moral calculus involved in all sorts of decisions. This does not mean that economics is purely about cold rationality. Think of a market.

At its simplest, it is just a mechanism to allocate scarce resources, buyers and sellers meet in the marketplace to consensually exchange goods and services, but markets are not. The infallible mechanisms they are sometimes perceived to be. Not every good can be bought and sold freely, and some things like ivory need to be more strictly regulated than others. Imagine, for example, a market in which babies could be traded for cash by parents and adopters.

It is easy enough to envisage both parties reaching a mutually beneficial agreement, but here economists would raise an objection. From their point of view, this exchange fails because it neglects the interests of a third party, namely the baby. This kind of market failure is the result of what economists call an externality, the cost of an exchange, borne by a third party, who cannot consent to the exchange. And that is where regulation comes in.

It is an attempt to safeguard the interests of all parties to an exchange, whether they are those of babies, elephants or the environment.
