The concept of a monetary union today implies a multilateral entity that centralizes the emission of a common currency shared by multiple countries.

In 1492, Spain's Alhambra Decree forced Jews to convert to Christianity or face expulsion, leading many to become conversos. Portugal issued a similar edict in 1496. Driven by a desire for religious homogeneity, these measures led to persistent discrimination based on Jewish ancestry. How did this new group of New Christians defend their interests and thrive in economic and social spheres, building connections with Europe, Africa, ...

In today's political discussions, the endorsement of free trade is commonly linked with perspectives that lean toward the right side of the spectrum. However, it's crucial to recognize that the roots of free trade and classical liberalism extend beyond contemporary left-right divides. As a result, the promotion of free trade has profoundly impacted modern ideologies across the political spectrum. Originating as a response to the im...

From the 11th to 14th centuries, the Roman Catholic Church was Europe’s largest and most organized institution. Unlike any other entity at the time, it had the capacity to tax, create law and administer justice. Secular authorities had to grapple with it. They competed and allied with it. But most importantly, they emulated it. Today we will be talking with Dr. Anna Grzymala-Busse about her most recent book, Sacred Foundations: The...

"Too much money spent chasing too few goods" is the preferred explanation that most people think about when discussing the causes of inflation. But how generally applicable is said argument to our modern economy? Today we will be talking with Dr. John Cochrane, who will speak about his most recent book, The Fiscal Theory of the Price Level, where he argues that changes in price levels depend rather on the expectations of the abilit...

We tend to think of political borders as exogenous artifacts that are imposed in a top-down manner by governments with imperial ambitions. And while this is true in some cases, there is a more significant case to be made for the alternative, where borders and jurisdictions are endogenous to the populations that draw them.

As its name implies, the Renaissance is often thought of as a turning point in human history. Art is its most celebrated, long-lasting legacy. And the romanticized perception of the artist as a genius is its byproduct. But how exactly did artists become artists? Who commissioned their work? How could the patrons oversee the quality of the work they were commissioning? We will be talking today with Ennio Piano about the economics of...

Nigeria is Africa’s largest state by population size and by nominal GDP. It is a multiethnic state where more than 250 minorities coexist.

How can a large and diverse state like Nigeria be fully integrated into one common Nation? Today, Dr. Okunogbe will talk to us about her recent research....

Up until the 18th century, China was the world’s hegemon. So how did it get there in the first place? And why did the Empire collapse abruptly in the 20th century? Today, Yuhua Wang will talk to us about his most recent book, where he argues the Chinese state experienced a gradual decline in its state capacity caused by a sovereign’s dilemma, where cohesive elites strengthened the state but also weakened the position of the emperor...

Today, Oded Galor joins us to discuss his most recent book on this topic: The Journey of Humanity.
