The government-driven knowledge network of the hydrogen energy sector in Korea provides a good case study for an R&D network incorporating necessary building blocks; it can be regarded as a precursor to an emerging sector even before business relationships form, especially one which involves...

Patents are typically characterized as assets of great values. Nevertheless, there are many patents that are actually never used. In this article, we claim that there is a relationship between the duration of patents and the characteristics of the underlying invention. From the viewpoint of...

In this study we propose a mathematical definition of the consumption efficiency of multi-attribute products in the price–quality space. A new model, the discrete Range Adjusted Measure (RAM) model, is suggested as an empirical tool to measure the level of consumption efficiency. We further...

Shadow price is one of the most important pieces of information in environmental decision making. Two different approaches—namely, economic and engineering—have been applied to obtain the shadow price of undesirable outputs, while using different methodological backgrounds and perspectives....

This empirical study examines productivity changes in Japan and South Korea during 1973–2006 and 1980–2009, respectively, in order to assess how investment in information and communications technology (ICT) affects energy demand. A dynamic factor demand model is applied to link...

This study is conducted to develop a new measurement tool to analyze the extent of innovation by developing nations. The role of science and technology in enhancing the rate of innovation is also investigated. The existing methods for measuring innovation such as Technology Index (WEF),...

The Korean electricity industry saw significant changes following the reform in April 2001. Until the last decade, the industry was monopolized by the Korea Electric Power Corporation (KEPCO), a state-owned, vertically integrated company. The 2001 reform divided KEPCO's power generation division...

This paper analyses the effect of military expenditure on economic growth. With various channels through which military expenditure may influence economic growth, much of the defense economics literature has found inconsistent results. This study is based on the national defense expense for the...

In the article, we analyze that how the innovative activity affects to income redistribution, which have been considered for prolonged period. The effect of spending on R&D usually affects to higher income level; however, the lower income group also becomes easier to approach to high-tech...

A computable general equilibrium (CGE) model is useful for the calculation of macroeconomic effects caused by policy impacts, but it has been considered a sticking point to evaluate how well the CGE model describes the real economy. Among various possible reasons for the difference between the...
