‘Bubble’ diagrams are quite useful in revealing some of the properties found in the competitive models of international trade. These diagrams use circles (bubbles) to indicate commodity outputs and connecting lines to indicate factor inputs. Models such as the 2 × 2 and n × n H eckscher– O hlin models as well as the 3 × 2 (and extensions) specific factors model are discussed. For example, a model with some factor mobility between countries (say capital into a foreign enclave) is discussed for both model types. As well, close analogies are made to issues in labour economics in which both skilled and unskilled labour are used as inputs.
