유상증자의 주가하락에 대하여 유상증자 공시일전 내부자순매수를 종속변수로 설정하여 선형회귀분석한 결과, 이전의 논문결과와는 달리 유상증자규모효와 자본구조변화효과는 보이지 않았으며, 반면에 유상증자의 주가하락이 내부자순매수와 통계적 유의성이 높은 비례관계가 있음을 밝혀 내었다. 이 결과는 유상증자규모효과로 인한 가격 압박가설과 자본구조변화효과로 인한 부의 이전가설을 기각시키고 정보전달가설이 유상증자의 주식 가격 하락현상을 설명하는 설득력 있는 가설임을 시사하고 있다.

This paper investigated the information spillover effect between stock market and bond market with the KOSPI daily index and MMF yield data. The overall analysis period is from May 2, 1997 to August 30, 2019. The empirical analysis was conducted by dividing the period from May 2, 1997 to December 30, 2008 before the global financial crisis, and from December 30, 2008 to August 30, 2019 after the global financial crisis, and the overall analysis period. The analysis shows that the EGARCH model considering asymmetric variability is suitable. The price spillover effect and volatility spillover effect existed in both directions between the stock market and the bond market, and the price transfer effect was greater in the period before the global financial crisis than in the period after the global financial crisis. Asymmetric volatility in information between stock and bond markets appears to exist in both markets.

This article analyzes the spillover effects by dividing the weekly rate of return on apartment prices in 70 si-gun-gu (local area) in the Capital Region into three periods: the entire period (April 2008~August 2021); the period before the price surge (April 2008~October 2018); and the period of price surge (November, 2018~August 2021), based on a consideration of the cycle of fluctuations in apartment sales prices and the timing of the current government's policy interventions. The results obtained from this analysis are summarized as follows. First, the analysis of the spillover effects is similar to or different from the results of existing work depending on the period. The analysis of the spillover effects on the entire period and the period before the price surge shows that the 'Gangnam' effect exists in the apartment market in the Capital Region. On the other hand, the analysis of the spillover effects on the period of price surge reveals different results than before. The spillover effect index calculated through the analysis of the rolling sample decreases during the decline in the cycle of apartment sales prices, while the opposite trend is shown during the upward period. Looking at the timing between the peak of the spillover effect index and policy interventions, it appears that the government's policy interventions took place after the peak of the spillover effect index in 2017, before the peak in 2018 and 2019, and around or after the peak after 2020.

경쟁정책은 기술혁신의 양과 기술이전, 즉 라이센싱, 그리고 제품의 가격과 생산량에 영향을 미친다. 문제는 이 3개의 항목 중 어디에 경쟁정책의 초점이 맞추어져야 하는가이다. 전통적으로 경쟁정책은 생산량과 가격의 움직임에 관심을 가졌는 바, 이제 지식경제화 시대에서 특히 지적재산권 분야에서는 혁신의 확산의 경쟁적 효과에 초점을 맞추어야 할 필요가 있다. 즉 라이센싱의 경쟁적 효과를 면밀히 분석해야 하는 것이다.

This paper empirically examined the relationship between the housing market and the stock market to investigate the price and the asymmetric volatility spillover effects. The monthly housing price index and the monthly KOSPI were used for analysis. This research employed the EGARCH model. The analysis period was from January 1986 until June 2021 with periodization centered on the Asian Financial Crisis: before and after the crisis - the end of December 1997. The EGARCH model allows analysis of 'good news' and 'bad news' in understanding volatility. The price spillover effect was observed one way from the stock market to the housing market. On the contrary, the spillover effect was not found from the housing market to the stock market. The empirical evidence suggests that there are price and asymmetric volatility effects in the entire period of analysis in both housing and the stock markets. In the housing market, the negative effects of information were found pre-financial crisis while the positive effects, in other periods. However, in the stock market, the negative effects of information were found in the pre- and post-financial crisis periods. This means that the housing market is more affected by 'good news' than 'bad news' when information spreads to the markets while the stock market is more affected by 'bad news' than 'good news'. It is of significance to discover the variable returns by different information.

This study attempts to analyze the effects of distance-accessibility to the complex shopping mall of 'Lotte Mall-Suwon', located at the old central and catchment district of the Suwon station in the Province of Gyeonngi, on the prices of its neighboring apartments within the Gwonseon-gu of Suwon City by using the hierarchical and linear-difference in difference regression method. The results of the analysis are as follows. First, before construction the effects of distance-accessibility show the U-shaped pattern, suggesting that the negative external effects of noise and traffic congestion around the Suwon Station affected the prices of its neighboring apartments within the Gwonseon-gu of Suwon City. Second, the effects of distance-accessibility at different times, such as the construction period and after the opening, are statistically significant only in the latter, indicating the reverse U-shaped pattern unlike before the opening. This means that after the opening of the complex shopping mall its external effects as a leisure and convenience space have a positive effect on the prices of its neighboring apartments within the Gwonseon-gu of Suwon City. Third, the effects of distance-accessibility is at an inflection point around 1.6-1.7 kilometers, which means that the U-shaped distance-decay pattern before construction, while the reverse U-shaped pattern is shown after the opening of opening. The latter implies that apartments that are very close to the mall within the Gwonseon-gu of Suwon City enjoy relatively small positive externalities. Therefore, they are exposed to some negative external effects of noise and traffic congestion, but apartments with some distance apart within the Gwonseon-gu of Suwon City maximize those positive externalities. These results suggest that the effects to distance-accessibility are different from location to location.

SHIFT is public rental housing policy introduced by Seoul Metropolitan in 2007, which works as Chonsei(korean unique deposit rental system). This paper examines the effect of SHIFT on Chonsei prices of neighborhood apartments. To estimate the change in prices of Chonsei after the provision of SHIFT, I collect data on Chonsei prices of apartments within a 5km radius from the SHIFT housings. Summary of main results are following. Chonsei prices of the apartments within a 2-3km radius decreased by 4.4% after the provision of SHIFT housings. In contrast, when it comes to apartments within a 1-2km radius, I can't find the stochastic relationship between the provision of SHIFT hosing and price changes. This results can be explained by "Offset effects" caused by real estate development. Provision of SHIFT can sequentially induce nearby area's development, which plays a factor in the effect of price increases. And this offset effects varies in each apartment complex depending on demand for Chonsei and supply of the SHIFT.

This study tests the price discovery from US Treasury bond markets to Korean bond markets using the daily returns of Korean bond data (CD, 3-year T-note, 5-year T-note, 5-year corporate note) and US treasury bond markets (3-month T-bill, 5-year T-note 10-year T-bond) from July 1, 1998 to December 31, 2003. For further research, we divide full data into two sub-samples on the basis of the start-up of bond valuation system in Korean bond market July 1, 2000, employing uni-variate AR(1)-GARCH(1,1)-M model. The main results are as follows. First the volatility spillover effects from US Treasury bond markets (3-month T-bill, 5-year T-note, 10-year T-bond) to Korean Treasury and Corporate bond markets (CD, 3-year T-note, 5-year T-note, 5-year corporate note) are significantly found at 1% confidence level. Second, the price discovery function from US bond markets to Korean bond markets in the sub-data of the pre-bond valuation system exists much stronger and more persistent than those of the post-bond valuation system. In particular, the role of 10-year T-bond compared with 3-month T-bill and 5-year T-note is outstanding. We imply these findings result from the international capital market integration which is accelerated by the broad opening of Korean capital market after 1997 Korean currency crisis and the development of telecommunication skill. In addition, these results are meaningful for bond investors who are in charge of capital asset pricing valuation, risk management, and international portfolio management.

While new evidence on international spillover effects has been widely discussed around the globe, the MENA (Middle East and North African) region has received little attention concerning international transmission of stock market movements. In this paper, we discuss international spillover effects between the major developed markets (US, Japan and Germany) and the emerging markets in the MENA region (Turkey and Egypt). While GARCH-type models have mainly been used to investigate international stock market spillovers in much of previous studies, we develop new testing strategies based on discrete wavelet decomposition. The basic finding is that price as well as volatility spillover effects exist from the developed stock markets to the MENA counterparts, although evidence for price spillover to the Egyptian market is rather weak. As for the interdependence of the major MENA stock markets, no spillover effects are found between these markets, while the two MENA markets are somewhat related with each other.

본고(本稿)는 1986년 이후 우리나라의 경상수지흑자(經常收支黑字) 및 수출입행태(輸出入行態)를 실증적(實證的)으로 분석(分析)하고 그 원인(原因)을 살펴보고자 하는 데 목적이 있다. 1986년의 해외여건호전(海外與件好轉)으로 경상수지(經常收支)가 흑자(黑字)로 반전하게 되자 1987년 이후에는 원화(貨)를 상당히 절상(切上)하였음에도 불구하고 경상수지흑자감소(經常收支黑字減少)의 효과가 1988년까지는 뚜렷이 나타나지 않았는데, 이는 환율(換率)의 변화를 수출가격(輸出價格)에 100% 전가(轉嫁)하지 않으려는 기업(企業)의 가격결정정책(價格決定政策)으로 수출물량감소(輸出物量減少)가 지연되고 원화절상(貨切上)의 J-커브효과(效果)가 발생했기 때문이다. 한편 1986년 이후 경상수지흑자기조하(經常收支黑字基調下)에서 수출입행태(輸出入行態)와 구조적(構造的) 안정성(安定性)을 계량적(計量的) 방법(方法)으로 검증한 결과 검증방법(檢證方法)에 따라 구조적(構造的) 안정성(安定性)의 가설(假設)이 기각되기도 하였는데 특히 수출단가(輸出單價) 및 수입물량결정행태(輸入物量決定行態)의 경우 1985년 이전에 비하여 구조적(構造的)으로 상당한 변화(變花)가 있었던 것으로 나타났다.
