A wide variety of retailers (supermarkets, home electronics, Internet shops, etc.) provide scanner data containing information at the level barcode, e.g. Global Trade Item Number (GTIN). As complete transaction information, we may use expenditure shares items as weightsfor calculating price indices lowest (elementary) aggregation.

Regulatory competition between the US and EU influences the development of the standards that define global ICT networks. Traditional standard-setting organizations that once developed those standards have been marginalized by the rapid pace of innovation in ICT, and informal standard-setting organizations have rushed into the breach. US policy favors informal standard-setting processes and oft...

The use of multilateral well is becoming an emerging method to improve oil recovery efficiently and to drain reservoirs more efficacious. By developing drilling technology, completing the oil wells as multilateral wells become more interesting especially from economic point of view. On the other hand, lack of any means for forecasting the performance of this type of wells causes drilling of...

This paper compares sequential trade liberalization through a preferential trade agreement (PTA) and one-shot multilateral trade liberalization with respect to the speed with which countries attain multilateral free trade. We build a three-country oligopoly model, including one developing country whose domestic firm initially uses old technology. Firm-level adoption of new technology and countr...

The four-channel architecture in teleoperation with force feedback has been studied in various existing literature. However, most of them focused on Lawrence architecture and did not research other cases. This paper proposes two other four-channel architectures: passive four-channel architecture and passive four-channel architecture with operator force. Furthermore, two types of multilateral sh...

Multilateral systems involving haptic information sharing between several users have recently found interesting applications in cooperative haptic teleoperation and haptic-assisted training. It is intuitively understood that some tasks are performed more effectively with two hands or through collaboration than one hand or individual operation. By using multiple user interfaces (“masters”) and o...
