The Economic Complexity Index (ECI) and the Product Complexity Index (PCI) are, respectively, measures of the relative knowledge intensity of an economy or a product.
ECI and PCI values are estimated directly from matrices summarizing the geography of economic activity, and can be calculated on demand.
Formally, the complexity of location (ECI) is a function of the complexity of the activities present in it. Similarly, the complexity of an activity (PCI) is a function of the complexities of the locations where that activity is present.
These are the rankings of the OEC 3.0 version for the Product Complexity Index.
Looking for a forecasting tool?
The OEC forecast section allows you to create custom LSTM models and fit them directly over any of the millions of time series we have available.
The Economic Complexity Index (ECI) is a measure of economic capacity that is predictive of income, economic growth, income inequality & greehouse gas emissions. Technically, ECI is a principal component of a matrix connecting similar locations.
