在本文中，我们研究的经济影响的信息和通信技术（ICT）的创新，在一般均衡框架内的经验估计的恒定弹性的替代（CES）生产前沿。这种创新不仅带来生产力增长和价格变化，而且还引发生产和贸易模式的经济结构变化。这个过程表面上增加了社会福利。为了研究ICT创新的影响，我们构建了一个涵盖日韩两国350种商品和贸易部门的双边一般均衡模型。我们估计所有CES参数从公布的统计数据，包括链接的投入产出表和商品贸易统计数据库。一个小的外部生产力冲击的信息和通信技术的审查在这两个国家的所有商品的潜在价格下降。
In this paper, we examine the economic impact of information and communication technology (ICT) innovation, within a general equilibrium framework of empirically estimated constant-elasticity-of-substitution (CES) production frontiers. Such innovation generates not only productivity growth and price changes, but it also triggers changes in the economic structure of production and trade patterns. This process ostensibly increases the social welfare. To study the impact of ICT innovation, we construct a bilateral general-equilibrium model that spans 350 commodities and sectors of trade between Japan and the Republic of Korea. We estimate all CES parameters from published statistics, including linked input–output tables and Comtrade databases. A small exogenous productivity shock in the ICT is examined in terms of potential price reductions of all commodities in both countries.
