Just released, the Chinn-Ito index is available here.normalized to [0,1]of which 1 is the most open, this is the world.
The current dataset description is Ito and Qin(2022).
This is Hero I constructed this index because at the time there was almost no single, widely available, and continuously updated measure of financial openness, except Quinn’s (APSR1997) measures, the coverage of which was relatively limited at that time. IMF-based individual dummy variables (old) in Law In my early empirical analysis of financial development, the classification of controls (exchange rate, export earnings, capital account, current account) was uninformative (Chinn, 2004, Ungated version here). The Chinn-Ito index is based on the above-mentioned IMF legal classification, converted into a single index by using the first principal component (essentially a smoothed capital account component), and was developed for projects assessing financial openness and financial development. Related, posted in go (2006) (With help from many friends, including Ashok Mody and Antu Panini Murshid).
Quinn, Schindler and Akio Toyoda (International Monetary Fund Economic Review 2011) Provides early comparison of measures.The most recent comparison is at Graebner et al. (2021) and EErten et al. (2021). Overall, these measures go hand in hand.
