This study aims to examine an effective path that links the use of export promotion programs(EPPs) to the export performance of SMEs. In particular, the study focuses on what role the export innovativeness of SMEs plays between EPPs and export performance. In order to verify the conceptual model, the structural equation modeling is applied, using the data collected from a sample of 152 Korean SME exporters. The study highlights the notion that the relationship between the use of EPPs and export performance is not direct and that higher performance can be achieved through export innovativeness, the ability to reconstruct internal resources and to respond quickly to changes in the export market. The results of the empirical analysis show that EPPs partially mediate the relationship between export market-orientation and export innovativeness, and that such mediated export innovativeness continues to fully mediate the relationship between EPPs and export performance. That is, if SMEs make good use of EPPs that meet their needs, they can be encouraged to re-bundle or strengthen their existing resources and capabilities, which in turn lead to higher export performance. The study thus helps extend understanding of EPPs and export performance literature.

This paper proposes a Cournot model that can be used to analyze the strategic behaviors of generation companies which try to maximize their profits in an imperfectly competitive electricity and carbon markets. The proposed model consists of two parts. First, the strategic behaviors of generation companies are modeled based on the Cournot theory. Second, the market operation is modeled based on the assumption that the market operator tries to maximize the total social welfare in consideration of environmental welfare. To find the Nash equilibrium of the proposed model, the two-level optimization technique is used. The proposed method has been applied to an illustrative example of oligopolistic markets. We found that the proposed method has strong potential to analyze the influence of the strategic biddings of the generation companies and the impact of renewable generator on markets where the competitiveness of the markets is not fully developed.

The purpose of this study is to provide the strategic implication of the Korean open air market by examining the factors affecting their competitiveness. I have undertaken empirical research that uses the methodology of a mixture regression modeling, as a way to ascertain the determinants of competitiveness for the Korean open air market. I construct a mixture regression model which uses the proportions of merchandise categories as explanatory variables and the number of visitors as a dependent variable. The analysis of results show that competitive and non-competitive markets have different proportions of merchandise categories. The finding shows that stock farm products and home appliances are major influencers on the number of visitors in neighborhood markets. The finding also presents that stock farm products and processed foods are major influencers on the number of visitors in small & medium-sized city markets.

Due to the proliferation of smart devices, worldwide market growth of e-book content steep, but the domestic market shows relatively low growth rate and small size. In this study, a distribution modeling of the e-book business as a way to solve the problem of the domestic market of disabled was carried out to analyze the Amazon.com and Apple's e-book content distribution structure of the active leader in the U.S. market. And we tried to suggest a solution by investigation and analysis of the college students's receptive attitude on the e-book content as the main target to enable the markets based on the interest for publication. In adoption attitude survey, mainly low-readability and lack of content problem were reasons not to accommodate. There is a need to improve the quantity and quality of content through with technological advances and market participation together. For more participation, we expect to take advantage of the results of this study to establish or improve the systematic distribution structure.

As the service market is increasingly competitive, internal marketing, marketing orientation, and customer satisfaction are becoming a crucial issue to the survival and growth of the service firms. This Study examined the structure modeling of internal marketing, market orientation, and customer satisfaction to verify the relationship among construct variables. Conslusively, the higher degree of internal marketing and market orientation, the higher degree of customer satisfaction. Specifically, The positive impact of internal marketing, customer orientation and competitor orientation on customer satisfaction is verified respectively. But, the impact of interfunctional coordination on customer satisfaction is rejected. The company is required to intensify interfunctional coordination in company operation process to boost sustainable competative advantage.

Apartment brand has been used as a new strategy in Korean housing market to fulfill customer's changing needs for buying houses. A number of construction companies have succeeded in brand awareness and image building, however, they still struggle to establish brand loyalty and manage brand equity elements in balance. The purpose of this study is to analyze the brand equity building process of apartment products in Korean housing market and determine causal relationships among variables to propose strategies for long-term prosperity of the construction companies. System Dynamics modeling method is applied to describe how variables affect and are linked to each other in terms of building equity and enhancing company profits from customers' brand awareness to brand loyalty. Based on the analysis model, strategies for construction companies depending on their market share were proposed and this may support the company to achieve financial success and competitiveness among its competitors in the fast-changing market.

Recently, housing prices have surged, and the government has implemented various regulations, such as finance and taxes. Because of the policy, the nationwide housing price have stabilized, but polarization has occurred. Some argue that regulation can adversely affect the actual demand. Therefore, not only the correlation between market variables but also ripple effect of policy has to be analyzed in policy planning and analysis from a microscopic point of view. In this study, a simulation model was developed by integrating system dynamics for analyzing market structure and agent-based model for modeling decision process of market participants. This research applied the financial regulation and the tax regulation to the model and evaluated the policy effectiveness. This study reveals which feedback dominates according to the policies, which have same purpose. It is because market participants make different decision for each policy. Furthermore, there were other ripple effects not only in the policy target submarket but also in other submarket.

The stochastic volatility (SV) model is one of the main methods of modeling time-varying volatility. In particular, SV model is actively used in estimation and prediction of financial market volatility and option pricing. This paper attempts to model the time-varying volatility of the bitcoin market price using SV model. Hidden Markov model (HMM) is combined with the SV model to capture characteristics of regime switching of the market. The HMM is useful for recognizing patterns of time series to divide the regime of market volatility. This study estimated the volatility of bitcoin by using data from Upbit, a cryptocurrency trading site, and analyzed it by dividing the volatility regime of the market to improve the performance of the SV model. The MCMC technique is used to estimate the parameters of the SV model, and the performance of the model is verified through evaluation criteria such as MAPE and MSE.

The purpose of this study was to examine the effectiveness and efficiency of a policy by comparing and analyzing the impact of the rice market isolation system and production adjustment system (strategic crops direct payment system that induces the cultivation of other crops instead of rice) on rice supply, rice price, and government's financial expenditure. To achieve this purpose, a rice supply and demand forecasting and policy simulation model was developed in this study using a partial equilibrium model limited to a single item (rice), a dynamic equation model system, and a structural equation system that reflects the casual relationship between variables with economic theory. The rice policy analysis model used a recursive model and not a simultaneous equation model. The policy is distinct from that of previous studies, in which changes in government's policy affected the price of rice during harvest and the lean season before the next harvest, and price changes affected the supply and demand of rice according to the modeling, that is, a more specific policy effect analysis. The analysis showed that the market isolation system increased government's financial expenditure compared to the production adjustment system, suggesting low policy financial efficiency, low policy effectiveness on target, and increased harvest price. In particular, the market isolation system temporarily increased the price during harvest season but decreased the price during the lean season due to an increase in ending stock caused by increased production and government stock. Therefore, a decrease in price during the lean season may decrease annual farm-gate prices, and the reverse seasonal amplitude is expected to intensify.
