Indices

We provide five indices that amalgamate the content of a treaty into an expression of the overall bargaining settlement it contains. These indices are useful starting points for comparing treaties, but they are only a very rough approximation, and we recommend a detailed examination of the text before drawing any firm conclusions. To create the indices, each clause in the treaty was assigned a value between 0 and 1, where 1 represents a greater taxing right over inward investment. Indices are averages of these values over a particular group of clause, as follows.

Source. All fields in the dataset that relate to the balance of taxing rights.

PE. Fields related to Permanent Establishment, which refers to the threshold above which a foreign company’s presence in a country becomes taxable. Drawn from article 5 of the model treaties.

WHT Rates. An average of the fields coding withholding tax rates in each treaty. These are taxes imposed on cross-border investment, which treaties either prevent or limit to a maximum rate. Articles 10 to 12A of the model treaties.

Other. The remaining fields that relate to the distribution of taxing rights, drawn from articles 7, 8, 12, 13, 16 and 21 of the models.

UN. A strict analysis of only the provisions that vary between the UN and OECD models. It excludes, for example, WHT rates, since these are not specified in the UN model.
