본 연구는 부동산 가격 추정을 위해 자주 활용되는 헤도닉 가격모형(Hedonic Pricing Model)에서의 설명변수, 즉 지가형성요인의 선별 중요성에 대해 기술하고, 이러한 지가형성요인 및 그 효과가 시간의 경과에 따라 어떻게 변화하는지 실증적으로 검토하였다. 전주시를 사례 지역으로 하여 17년간 반복 측정된 표준지 공시지가를 분석 대상으로 하였으며, 자료가 가지는 포섭구조(nested structure) 및 종단성(longitudinal characteristics)을 고려하여 3개 수준으로 구성된 다수준모형(multi-level model)을 설정하여 적합 정도를 평가하였다. 지가형성요인은 공시지가 산정시 활용되는 헤도닉 가격모형의 일종인 비준표(比準表)에 포함된 항목을 중심으로 살펴보았다. 분석 결과, 17년간의 지가 변동 추세는 전주시 세부지역별로 상승 또는 하락하는 등 지역마다 다른 추이를 보였으며, 따라서 종단효과의 모델 반영이 필요함이 확인되었다. 또한 일반적으로 중요하다고 여겨지는 지가형성요인 중 유의하지 않은 요인이 발견되었으며, 특정 시점에서 영향력이 상당히 큰 것으로 판명된 지가형성요인도 시간의 경과에 따라 그 영향력이 약해지는가 하면, 반대로 지가에 미치는 영향력이 초기에는 미약하였으나 점차 뚜렷해지는 요인이 파악되었다. 향후 헤도닉 모형 적용시 이러한 지가형성요인의 동태성을 모델의 구성요소로 고려할 경우 보다 정확한 가격 추정이 가능해질 것이다.

This paper empirically analyzed consumer price search behavior using Web log data of a Korean web site for price comparison. Consumer click-stream data of the site was used to test the effects of price level, product category, third party certification, reputation of retailers on click behavior. According to the descriptive statistics, 67.4% of shopbot users clicked the offer which was the lowest price returned in a search. We found that third party certification and reputation of retailers were significant determinants of clicking the lowest priced offer from legit analysis. We also applied Tobit regression analysis to estimate the price premium of the two determinants, but only reputation of retailers was found to have price premium of 4.9%.

With the targeted coffee consumers in Kwangju city, South Korea, this paper investigates a few determinants such as taste, aroma, mouth-feel, and satisfaction to influence coffee price, based upon self-evaluations by those who enjoy specialty coffee. Using both simple regression and standard multiple regression analyses, it turned out that tastes, smell, mouth-feel, and satisfaction of specialty coffee had effects on coffee price. This study implies that when coffee consumers decide coffee price, they consider multiple factors to influence their overall satisfaction in multiple aspects than a single facet like taste, aroma, and mouth-feel. Practical and theoretical discussion and implications are suggested for the following studies.

China is playing more predominant role in the liquefied natural gas (LNG) market worldwide and LNG import price is subject to various factors both at home and abroad. Nevertheless, previous studies rarely heed a multiple of factors. A time-varying parameter factor augmented vector auto-regression (TVP-FAVAR) model is adopted to discover the determinants of China's LNG import price and their dynamic impacts from January 2012 to December 2021. According to the findings, market fundamentals have a greater impact on the import price of natural gas in China than overall economic demand, financial considerations, and world oil prices. The primary determinants include domestic gas consumption, consumer confidence and other demand-side information. Then, there are diverse and time-varying spillover effects of the four common determinants on the volatility of China's LNG import price at different intervals and time nodes. The price volatility is more sensitive and long-lasting to domestic natural gas pricing reform than other negative shocks such as the Sino-US trade war and the COVID-19 pandemic. The results in this study further proves the importance of domestic natural gas market liberalization. China ought to do more to support the further marketization of natural gas prices while working harder to guarantee natural gas supplies.

The aim of the study is to implement a factor analysis of the determinants of pricing in a state-regulated competitive market using economic and mathematical modelling methods and to develop ways to improve the pricing environment of the market under study. The purpose of the work defines the main objectives: (i) to investigate the features of the competitive model of the Ukrainian flour market; (ii) to analyse the current price conjuncture of the flour market and the dynamics of the main determinants of pricing; (iii)to develop ways of improving the price situation on the flour market on the basis of the factor analysis on the results of economic and mathematical modelling. In order to ensure the reliability and validity of the research results, the following methods were applied: the logical-dialectical method of scientific knowledge in the study of the main theoretical aspects of flour market functioning, the method of logical generalisation and synthesis, comparison, factor analysis, correlation and regression analysis, the graphical method, etc. It has been shown that pricing in a state-regulated competitive market has its own characteristics. For example, in the flour market the price of goods cannot be influenced by producers (sellers) by any methods, therefore determinants of pricing by indirect influence have been taken into account. The five-factor power model of wheat flour price has been constructed. It was substantiated that the price of wheat flour in Ukraine is mostly influenced by consumer price index (0.92 %). The received complex model of wheat flour price may be used also for medium-term forecasting and working out the ways of price formation optimization in the flour market.

Purpose: The purpose of this study is to investigate the interaction effects between price determinants of artworks. We expand the methodology in art market by applying machine learning techniques to estimate the price of artworks and compare linear regression and machine learning in terms of prediction accuracy. Methods: Moderated regression analysis was performed to verify the interaction effects of artistic characteristics on price. The moderating effects were studied by confirming the significance level of the interaction terms of the derived regression equation. In order to derive price estimation model, we use multiple linear regression analysis, which is a parametric statistical technique, and k-nearest neighbor (kNN) regression, which is a nonparametric statistical technique in machine learning methods. Results: Mostly, the influences of the price determinants of art are different according to the auction types and the artist 's reputation. However, the auction type did not control the influence of the genre of the work on the price. As a result of the analysis, the kNN regression was superior to the linear regression analysis based on the prediction accuracy. Conclusion: It provides a theoretical basis for the complexity that exists between pricing determinant factors of artworks. In addition, the nonparametric models and machine learning techniques as well as existing parameter models are implemented to estimate the artworks' price.
