Governments have been very active in engaging in and in encouraging the improvements in transaction efficiency, including the provision of legal, social, and economic infrastructures. While this may partly be explained by the public goods nature, the presence of indirect network externalities due to the economies of specialization may also be important. The improvement in transaction (including communication and transportation) efficiency may generate benefits in excess of the direct private benefits through the promotion of higher degree of specialization. This is shown in the Yang-Ng framework of inframarginal analysis.
