An Analysis of Housing Sales Price Spillover
Lim Hyun-Joon, Kim Chanwoo, Hwang Na Yun, Lee Junghyuk
This study measures the time-varying spillover effects between regions and between
housing sales markets, which significantly influence housing price fluctuations,
by estimating the DCC-GARCH model and TVP-VAR model and applying
the spillover index. The results show that, as commonly believed, housing sales and
rental prices in the Gangnam area and the Seoul metropolitan area exert strong influence
on surrounding regions. Over time, the spillover effects were relatively
smaller during periods of housing price decline, and the influence of the Gangnam
area has been gradually decreasing in recent years. Additionally, the spillover effects
of rental prices were found to be at a similar level to those of housing sales
prices. These findings were consistent across both the DCC-GARCH model and the
TVP-VAR model, demonstrating the robustness of the results to the choice of
model. The results suggest that when formulating housing and regional development
policies for specific areas, it is crucial to consider not only the direct effects on
the targeted area but also the spillover effects on neighboring regions.
An Analysis of China's Fertility Determinants: A Focus on Women's Labor Force Participation
Jia Hui Li, Joo Yeon Sun
This study investigates the determinants of China¡¯s fertility rate using multiple linear regression, with a particular focus on female labor force participation. The analysis reveals that higher female labor force participation is positively associated with fertility. Fertility rates in the four major municipalities?Beijing, Shanghai, Chongqing, and Tianjin?remain lower than in other regions. The results also highlight significant regional disparities, emphasizing the importance of tailored population policies that consider local demographic and socioeconomic contexts. These findings suggest that declining fertility poses a critical social and economic challenge for China, requiring comprehensive policy interventions to support sustainable development. By providing empirical evidence on the interplay between female labor participation and fertility, this study contributes to a deeper understanding of population dynamics in the context of contemporary socioeconomic transformations.
Fake News and Political Polarization
Daeyoung Jeong, Insoo Park
This paper presents a theoretical analysis of the impact of fake news on electoral campaigns within networked communication. The foundational model involves strategic candidate selection and campaign planning by two political parties, with voters categorized into partisan and independent groups. Partisan voters receive information directly from party campaigns, while independent voters rely on interactions with partisans, resulting in a nuanced learning process. Our findings demonstrate a positive association between intensified communication and an increased production of fake news, highlighting the role of misinformation in exacerbating political polarization. Specifically, heightened communication between independent and partisan voters correlates with a higher likelihood of selecting extreme candidates in elections, accompanied by an increased prevalence of misinformation in political campaigns.
