The reason is that computers can replace routine tasks such as assembly-line or clerical work, while nonroutine tasks are more difficult to digitize, and computers facilitate large-scale data analysis, which complements the tasks of skilled workers. However, these developments can also be explained by trade-related arguments that emphasize the rapid increase of trade in intermediate products, such as parts and components - a key feature in electronics industries - and the offshoring of service activities. Trade in intermediate products and offshoring have often figured prominently in the trade-inequality debate in developed countries. Less costly and more sophisticated ICTs have enabled firms to profitably manage multifaceted procedures and undertake different stages of production in different geographical locations. As a result, some of the production of intermediate goods has moved from developed to developing countries, thereby spurring international trade in those goods.
