To enable the representation of the Earth's surface on a piece of paper, parameters of the size and the shape of the Earth and the origin and orientation of a co-ordinate system need to be defined. Such parameters are described by so-called Geodetic datums.
The general trade system is in use when the statistical territory of a country coincides with its economic territory. Consequently, under the general trade system, imports include all goods entering the economic territory of a compiling country and exports all goods leaving the economic territory of a compiling country.
The General Agreement on Trade in Services (GATS) is among the World Trade Organization's most important agreements. The accord, which came into force in January 1995, is the first and only set of multilateral rules covering international trade in services. It has been negotiated by the Governments themselves, and it sets the framework within which firms and individuals can operate. The GATS has two parts: the framework agreement containing the general rules and disciplines; and the national “schedules” which list individual countries’ specific commitments on access to their domestic markets by foreign suppliers
The General Agreement on Tariffs and Trade (GATT) is a multilateral agreement, originally negotiated in 1947 in Geneva among 23 countries, to reduce tariffs and other trade barriers. It provides a framework for periodic multilateral negotiations on trade liberalisation.
An aggregation method in which category "international prices" (reflecting relative category values) and country purchasing power parities (PPPs), (depicting relative country price levels) are estimated simultaneously from a system of linear equations. Has the property of base-country invariance, matrix consistency and transitivity.

A frequency ratio is the proportion of national tariff lines that are affected by a particular non- tariff barrier or by a specified group of non tariff barriers, irrespective of whether the products affected are actually imported
A free trade area is a grouping of countries within which tariffs and non-tariff trade barriers between the members are generally abolished but with no common trade policy toward non-members. The North American Free Trade Area (NAFTA) and the European Free Trade Association (EFTA) are examples of free trade areas.
Free trade occurs when goods and services can be bought and sold between countries or sub-national regions without tariffs, quotas or other restrictions being applied.
