This paper empirically analyzes the relationship between asymmetric regulation on mobile termination rates and mobile retail prices, using panel data collected from 20 OECD member countries for 22 quarters. In addition to the asymmetry of mobile access charges, the authors also focus on the...

This paper estimates consumer surplus in the Korean mobile telephone services (MTS) market. The Korean mobile telecommunications market has grown rapidly since 1997 when competition was introduced and Code Division Multiple Access (CDMA) technology was commercialized. Because consumer surplus is...

The goal of this work is to understand the structure and characteristics of technological knowledge flows between countries, institutions, and technology fields in the field of organic photovoltaic cells. This study was conducted in three stages: data collection, network creation, and network...

Information and Communications Technology (ICT) has become a necessity in social and economic development and is a leading sector to enable and drive growth in other sectors in Cambodia such as education, agriculture, and health. Recently, the mobile telecom service market in Cambodia has...

In order to cope with climate change, the development and deployment of Hydrogen Fuel Cell Vehicles (HFCVs) is becoming more important. In this study, we developed a forecasting model for HFCVs based on the generalized Bass diffusion model and a simulation model using system dynamics. Through...

By 2020, Korea has set itself the challenging target of reducing nationwide greenhouse gas emissions by 30%, more than the BAU (Business as Usual) scenario, as the implementation goal required to achieve the new national development paradigm of green growth. To achieve such a target, it is...

This paper presents an approach to estimating the health effects of an environmental hazard. The approach is general in nature, but is applied here to the case of air pollution. It uses a computer model involving ambient pollution and temperature input to simulate the exposures experienced by...

The relationship between short-term exposure to air pollution and mortality or morbidity has been the subject of much recent research. in which the standard method of analysis uses Poisson linear or additive models. In this paper, we use a Bayesian dynamic generalised linear model (DGLM) to...
