Given the limited availability of data in South Korea, this study proposes a method by which to estimate regional capital stock by modifying the benchmark year method (BYM) and applies it to estimate regional net capital stock by sector in transport infrastructure. First, it estimates time-varying sectoral depreciation rates using the sectoral net capital stock and the investment amount for each period. Second, it estimates the net capital stock of each period using the net capital stock in the base year and the investment in each period. Third, in order to ensure that the sum of net capital stocks by region is equal to the nationwide estimate, the national estimates are allocated to each region according to the proportion of the values derived from the previous stage. The proposed method can alleviate well-known problems associated with conventional BYMs, specifically the upward bias and arbitrary choice of the depreciation rate.

본 연구는 1980년부터 2000년 동안 9개 산업에서 정보통신 관련 자본량(IT Capital Stock)을 추정하고 이를 이용하여, 해당 산업들의 총 요소생산성에 대한 기여도를 분석하였다. 순차적 분석방법에 따른 분석결과는 기술혁신정도를 나타내는 대리변수인 총 요소생산성과 정보통신자본량이 단위근을 갖는 것으로 나타났으며, 두 변수사이에 장기적인 공적분 관계가 성립하였다. 정보통신자본이 총 요소생산성에 대한 기여도를 분석한 결과 사용하는 계량 추정량에 따라 정보통신자본의 1단위 증가는 0.19에서 0.07까지 총 요소생산성증가에 기여하는 것으로 나타났다. 따라서 우리나라 정보통신자본에 대한 장기적 패널자료를 구축하여 분석한 결과로 볼 때, 정보통신자본에 대한 Solow의 '생산성 역설'가설을 뒷받침하지 않는 것으로 나타났다.

Purpose - As the U.S.-China trade war has become considerably worse, the Chinese government is considering applying non-tariff barriers to trade, especially local contents rule. The main purpose of this research is to check whether it is suitable for Korean investors to invest in the current Chinese capital market. Design/methodology - In order to check the stability of the recent Chinese capital market, we investigated the behavior of foreign equity investment (including Korean equity investment) in the Chinese capital market after China announced the Shanghai-Hong Kong Stock Connect (SH-HK Connect). In this paper, we researched whether international portfolio investment would or would not contribute to an increase the volatility of an emerging market's stock market (Chinese capital market) when foreign investors make investment decisions based on the objective of short-term gains by rushing into countries whose markets are booming and fleeing from countries whose markets are falling. Findings - The empirical results indicate that foreign investors show strong, negative feedback trading behavior with regard to the stock index of the Shanghai Stock Exchange (SSE), and when the performance of foreign investors in the Chinese stock market was fairly good. Also, we found evidence that the behavior of foreign investors significantly decreased volatility in SSE stock returns. Consequently, the SH-HK Connect brought on a win-win effect for both the Chinese capital market and foreign investors. Originality/value - It appeared that the Chinese capital market was very suitable for Korean investors after the China's declaration of the SH-HK Connect. However, the win-win effect was brought on by the Chinese government's aggressive capital control but the capital controls could possibly cause financial turmoil in the Chinese capital market. Therefore, Chinese reform in industrial structure and the financial sector should keep pace with suitable capital control policies.

This study aims to examine the influence of capital structure on the business efficiency of joint stock commercial banks listed on the Vietnamese stock market. The article uses data collected from the financial statements of 15 prominent joint-stock commercial banks out of 27 joint-stock commercial banks listed in Vietnam from 2011 to 2021. The research uses E-view software in quantitative analysis to build regression models to determine the relationship and the impact of capital structure factors on the business efficiency of listed joint stock commercial banks. Research results show that ROA is affected by 2 variables of capital structure. It is the sum of customer deposits to total assets and total liabilities to total equity. Total debt to total equity and total customer deposits to total assets both have a negative effect on ROA. For the regression results of ROA with all control variables, the control variables have a positive relationship with the dependent variable. The article has provided recommendations based on the research findings to determine the proper capital structure. Managers must solve the outstanding amount of mobilized capital in previous years, combined with the bad debt handling activities that have arisen.

This paper examines the effects of information telecommunication (IT) capital and R&D stock variation on the growth of Korean industry, using a time series approach. Most specifically, we apply the Granger causality and impulse response analysis to our examination of Koreas industrial growth, IT capital, and R&D stocks. The Johansen co-integration test is performed in order to analyze long-term relations among these variables. This research explores the way in which IT capital and R&D stocks variation from economic shocks affects the growth of Koreas industrial sector. The effects are ambiguous, however, across industrial sectors. An impulse response function analysis shows that the effects of IT capital and R&D stock fluctuations in each industrial sector are presented for different time periods.

The estimate on volatility of stock price is related with optimum of portfolio and Important for allocation of capital asset. If the volatility of stock price is varied according to macroeconomic variables on monetary policy and industrial production, it will assist capital asset to allocate. This paper is related with stock market volatilities on macroeconomic variables in U.S. and Europe, Korea. And, it Is pertain to vary in time of this variables. Thus, this paper is related with volatilities of monetary and physical macroeconomic variables on basis of statistics. And, it is ranged front capital investment to portfolio allocation. Also, this paper takes out of sample forecast and study more after this. In case Germany, France, Italy and the Netherlands, the relative importance of monetary policy and Industrial production Is different from these countries. In case Italy and the Netherlands, monetary policy is primary factor at stabilizing for volatility of stock price. In case Korea, increasing monetary policy and industrial production is positively affected stock market. It is that the positive effect of stock price is caused by mollifying monetary policy and economic growth. Specially, this conclusion is similar to US. In Korea, gradual increase in monetary and industrial production is necessary to stability of stock market. It is different to previous results on basis of increasing stock price of money in long period.

인간자본론에 의하면 노동자들간의 임금격차는 인간자본 축적량의 차이에 의해 설명될 수 있는데, 인간자본스톡의 정도는 개인의 선택에 의해 결정된다. 그러나 만일 인간자본스톡에 대한 개인의 선택, 즉 인간자본에 대한 투자결정이 차별에서 영향을 받는다고 하면 인간자본스톡에 근거한 남녀간 임금격차의 설명은 편의를 갖게 된다. 대다수 여성의 경우 노동시장참가가 불연속적으로 이루어지므로 이를 예상(기대)하는 여성이 남성에 비하여 인간자본에 대한 투자를 상대적으로 적게 한다면, 남녀 임금격차를 설명하기 위해서 인간자본스톡변수 대신에 기대(expected) 인간자본스톡변수를 사용하는 것이 편의의 발생을 줄이고 더 정확한 분석결과를 얻을 수 있을 것이다.

국내증시는 1992년 1월 자본시장이 개방되고, 외국 자본의 비율이 꾸준히 증가하여 2022년 현재 국내 시장의 30%를 차지하고 있다. 따라서 국내 증시는 국내의 이슈보다는 외국의 이슈에 더 많은 영향을 받고 있다. 외국자본의 매매 동향은 환율변동과 유사한 흐름을 보이고 있다. 환율이 외국자본의 매매에 미치는 영향을 피어슨 상관관계를 이용하여 분석하고, 환율변동에 따른 투자전략을 마련하고 거시경제지표 중 하나인 환율의 변동을 미리 예측하여 선제적으로 주식투자에 활용할 수 있다면 높은 수익률을 기대할 것으로 보인다. 따라서 본 연구에서는 환율과 외국자본의 매매 패턴을 비교 분석하여 국내증시 전반에 영향을 미치는 중요한 요인인 환율에 따른 외국인 변수를 예측하여 매수와 매매의 타이밍을 판단하여 투자에 도움을 주기 위해 본 연구를 진행하였다.

It is generally believed that there is a trade-off between economic growth and environmental quality since pollutants are generated in the process of production and consumption of commodities. Several researchers have shown this prevailing belief using the short-term input-output models. The literature, however, shows that there have been few attempts to investigate the relationship using long-term forecasting models. This motivates the current paper. This paper attempts to build a reginal growth model in a partial equilibrium framework taking into consideration the requirements of capital invested for pollutant abatement. Model is largely neoclassical. Labor is assumed to move a region with high utility specified in regional per capita average was income and pollution level while capital is partially mobile to a region with high returns. The regional growth is explored in a phase diagram. The paper shows that there are two stable growth equilibria which a region can converge over time and that the equilibria are distinguished by the initial threshold capital stock that a region holds. If the initial capital stock of a region is over(under) than the threshold size, the region converges to the higher (lower) growth equilibrium over time. Moreover, based on this result an environmental quality enhancing policy is analyzed in the phase diagram. It has revealed that the policy calls for the relocation of growth equilibrium points, specifically speaking, it stimulates an increase in labor stock and a decrease in capital stock. Hence the paper has suggested that the prevailing belief which the environmental policy negatively impacts on a regional economic growth is not always true.
