This is the best book I’ve read this year. It is also an important book. In a world obsessed with AI, Max Bennett approaches intelligence from a key point of view: biology.

Our main model is a generalization of Kremer’s O-Ring model with factors that can be made specific to each economy and activity. In this model, the output of an economy in an activity is proportional to the probability that it is not missing the factors that the activity requires.

In the product space, the core-periphery structure tells us that capabilities are correlated (e.g. Singapore scores high across all capabilities & Mali scores low). In the case of the research space, the ring structure is given by the fact that each field is only similar to a few other fields.

We also show that our model explains differences in network structure, like those observed between the product space (a network with a core and a periphery) and the research space (which is shaped as a ring).

In a single-factor model, ECI separates economies that are better or worse endowed with the factor. In a model with many factors, ECI tells us which economies have a higher probability of being endowed with many of them--regardless of what these factors are.

NEW PAPER: The Theory of Economic Complexity
The Economic Complexity Index or ECI is a widely used empirical tool with an unclear theoretical basis. In this paper, we change that by formally deriving ECI for several production functions and showing what it really does. 👇🧵

17. Relatedness-complexity diagrams have been around for a long time (in 2011 we published them under the name: Export-Opportunity Spectrum (sorry for that :-)).
But more recently, they have become a core tool for the consulting industry focused on smart specialization.

4. So the heuristic that everyone has been using (I am guilty of this too) is to trade-off these variables by focusing on an "efficient frontier." These are products that are relatively close and valuable.

3. Ideally, economies want to focus on activities that are related (easies to enter) and also valuable (high complexity).
But that's not always an option.
Developing economies are often "close" to low complexity activities and "far" from valuable activities.

Did you know that Mexico is the number one source of imported beer in America?
This might surprise you, but Mexico is the number one exporter of beer in the world, far ahead from the Netherlands, Belgium, and Germany.
Much of this beer ends in the US.

Canada's main trade partner in the United States is Illinois, which is a big importer of Canadian oil.
But Michigan & Texas also have significant connections with Canada.
For Michigan, it is mainly automotive. For Texas it is assembled cars & oil.

Canada is in the car industry too, but it is also a key source of energy for the United States.
This year alone the US imported from Canada over $66B in crude petroleum and over $14B in refined petroleum and petroleum gas.
