This study analyses the impact of information and communication technology (ICT)-driven product and process innovation on productivity and economic output growth at the sectoral level in Korea. A traditional growth accounting framework is applied with a quality-adjusted price index on ICT capital and ICT intermediate goods. In the productivity analysis, the impact of ICT-driven process innovation weakens over time in both the manufacturing and service sectors. In the economic output growth analysis, ICT-driven product innovation largely influences the ICT producing manufacturing sector, and national economic growth has benefited from ICT-driven product innovation almost four times as much as from ICT-driven process innovation during 2000–2012.

Consumer decision-making within a specific product category can take many forms. This study investigates the individual-specific transferal processes in new product adoption through cognitive, affective, and conative stages. We propose a general and flexible Bayesian multivariate regression model and fit the model to survey data on dedicated E-book reader adoption. The results show that—among six possible transition paths—all paths are feasible for the decision-making process, except for the conative → cognitive → affective path. In terms of market share, those who follow the hierarchy of effect process describing the cognitive → affective → conative process has the biggest market share and those following affective → conative → cognitive path has the smallest share. The contribution of this research is twofold. From a theoretical perspective, this study developed an estimable model for capturing heterogeneity in consumers’ decision-making process. Practically, the study empirically shows that a variety of decision-making paths exist, using survey data on the Korean E-book reader market. In the substantive domain, capturing the heterogeneity of consumer decision-making could provide marketers with insights to help profile consumers and with a basis for customer segmentation.

This study uses data from the Korea business activity survey panel from 2008 to 2016 to examine the effects on the sustainable growth of firms that initially adopted Information Technology (IT) applications during 2010 to 2012 compared to those that did not. The effects are examined for four years after adoption and divided into areas such as sales, labor productivity, profitability, increases in male and female employment, wages, and exports. Because the effects of IT adoption are known to vary greatly depending on the industry, the manufacturing industry is divided into traditional, medium-tech, and hi-tech manufacturing, and the service industry is divided into the materials service and information service sectors; the effects on each sector are then observed. In addition, the propensity score matching methodology is used to overcome selection bias arising from a simple comparison between firms that began using IT and firms that did not. The results show that, although there was little impact on productivity, there were impacts on sales and employment and large differences were found between the industrial sectors.

The market share of electric vehicles is growing and the interest in these vehicles is rapidly increasing in industrialized countries. In the light of these circumstances, this study provides an integrated policy-making package, which includes key features for electric vehicle diffusion and its impact on the Korean power market. This research is based on a quantitative analysis with the following steps: (1) it analyzes drivers’ preferences for electric or traditional internal combustion engine (ICE) vehicles with respect to key automobile attributes and these key attributes indicate what policy makers should focus on; (2) it forecasts the achievable level of market share of electric vehicles in relation to improvements in their key attributes; and (3) it evaluates the impact of electric vehicle diffusion on the Korean power market based on an achievable level of market share with different charging demand profiles. Our results reveal the market share of electric vehicles can increase to around 40% of the total market share if the key features of electric vehicles reach a similar level to those of traditional vehicles. In this estimation, an increase in the power market’s system generation costs will reach around 10% of the cost in the baseline scenario, which differs slightly depending on charging demand profiles.

In this paper, we analyze effects of overlapping policy support. Specifically, we examine two Korean policies related to innovative SMEs, Venture certification and Inno-Biz certification, which have similar goals, targets and benefits. Methodologically, we use the difference in difference method with the propensity score matching method to reduce the selection bias that can occur in policy impact assessment studies. Our results show that in this case of overlapping homogeneous policies, Venture certification and Inno-Biz certification, the complementarity effect is negative. That is, simultaneously supporting these two policies produces no synergy. This result implies that rather than offering multiple supports through double certification of a single firm, offering Inno-Bizcertification to non-supported firms could better increase performance. In other words, policy makers have to consider overlapping policy support before implementing any new policies, and they should not support homogeneous policies for a single group of firms.

The main objective of this paper is to identify and analyze the key drivers behind changes of CO2 emissions in the residential sectors of the emerging economies, China and India. For the analysis, we investigate to what extent changes in residential emissions are due to changes in energy emissions coefficients, energy consumption structure, energy intensity, household income, and population size. We decompose the changes in residential CO2 emissions in China and India into these five contributing factors from 1990 to 2011 by applying the Logarithmic Mean Divisia Index (LMDI) method. Our results show that the increase in per capita income level was the biggest contributor to the increase of residential CO2 emissions, while the energy intensity effect had the largest effect on CO2 emissions reduction in residential sectors in both countries. This implies that investments for energy savings, technological improvements, and energy efficiency policies were effective in mitigating CO2 emissions. Our results also depict that the change in CO2 emission coefficients for fuels which include both direct and indirect emission coefficients slowed down the increase of residential emissions. Finally, our results demonstrate that changes in the population and energy consumption structure drove the increase in CO2 emissions.
