This study investigates the effect of life settlement on the monopolistic insurance market. In particular, we consider liquidity cost, which is the cost incurred to the insurer to meet the request of surrender, and trading cost, which is the transaction cost of the policyholders for the settlement. We first show that the introduction of a life settlement can increase insurance demand and enhance consumer welfare even when the trading cost is higher than the liquidity cost. That is, even if the settlement market is less efficient than the insurance market, both insurance demand and consumer welfare can be increased. Second, the insurer's profit can also be increased when settlement is introduced because not only can the insurer save the liquidity cost but also the demand of insurance increases. Lastly, insurance demand does not always decrease when both costs increase. Depending on the population distribution over the liquidity risk, the demand of insurance can be increased or decreased.

The liquidity risk is defined as an additional risk in the market due to the timing and size of a trade. A recent work by Cetin et ai. (2003) proposes a rigorous mathematical model incorporating this liquidity risk into the arbitrage pricing theory. A practical problem arising in a real market application is an estimation problem of a liquidity cost. In this paper, we propose to estimate the liquidity cost function in the context of Cetin et al. (2003) using the constrained least square (LS) method, and illustrate it by analyzing the Kellogg company data.

Purpose: This study aims to explore the relationship between stock liquidity and skewness risk-tail risk (stock price crash risk) in an emerging market, in which problems on liquidity are more severe than in developed markets. Research design, data, and methodology: Based on the Thai market stock exchange over the period of 2000 to 2019, our sample include 13,462 firm-period observations. We employ a panel regression models regarding to five liquidity measures. These five liquidity measures cover three dimensions of liquidity namely the volume-based, price-based, and transaction cost-based measures for the liquidity-tail risk relationship. Results: We find a positively significant relationship between stock liquidity and tail risk in all cases. The finding here shows that the higher the stock liquidity, the larger the tail risk is. Conclusion: As the prior studies show inconclusive effect of stock liquidity on stock price crash risk, we demonstrate that mixed results found in prior studies are probably driven from the type of liquidity measure. The stock liquidity-tail risk association is present in the Stock Exchange of Thailand. The results remain the same regardless of the definition of tail risk and liquidity factors. An endogeneity issue is addressed by employing the two-stage least squares regression.

블록체인 기반 탈중앙화 금융 시장의 등장과 함께 분산 금융 어플리케이션의 사용자와 자본 유동성이 크게 증가하고 있다. 자동화 마켓 메이커는 탈중앙화 거래 플랫폼의 유동성을 바탕으로 자동으로 거래 단가를 계산하는 프로토콜로, 거래 플랫폼의 유동성 풀을 활용하여 구매자와 판매자가 동 시간대에 존재하지 않아도 거래의 성사를 가능하게 하여 현재 탈중앙화 거래 시장에서 가장 일반적으로 사용되고 있다. 그러나 자동화 마켓 메이커는 거래의 비용 효율이 거래에 사용되는 특정 유동성 풀의 유동성 규모에 의존하여, 유동성 풀의 규모가 작고 거래의 규모가 클수록 거래의 비용 효율이 크게 감소한다는 단점이 있다. 이를 해결하기 위한 방법으로 상대적으로 유동성의 규모가 큰 유동성 풀로 거래 경로를 우회하여 비용 효율을 개선하는 거래 경로 라우팅 알고리즘이 채택되고 있지만, 단일 거래 경로만을 사용하기 때문에 여전히 개선의 여지가 존재한다. 본 논문에서는 거래 경로를 우회하는 것에 더하여 거래 규모를 분산하여 다수의 거래 경로를 동시에 탐색하는 다중 경로 라우팅 알고리즘을 제안하고, 해당 알고리즘을 사용하여 자동화 마켓 메이커 기반의 거래 환경에서 기존의 거래 경로 라우팅 알고리즘에 비해 거래의 비용 효율을 개선한다.

This study examines simultaneous relationships between regulatory capital, risk, and cost-inefficiency for a sample of 30 commercial banks in Bangladesh from 2006 to 2018. To conduct the analysis, we used the Generalized Methods of Moments (GMM) in an unbalanced panel data framework. The empirical results show that there is a negative and significant relationship between capital regulation and credit, and overall risk. It is also evident from the results that the capital adequacy ratio is positively and significantly related to default risk and liquidity risk. Therefore, higher capitalized banks take an effort to prevent more credit risk and promote financial stability by reducing liquidity risk. Results also report that banks have been characterized as inefficient, less capitalized, and high risk. On the other hand, efficient banks are more stable but have a high level of liquidity risk. Besides, from the size of the bank, large banks are defined as having lower regulatory capital, are more risk seekers but stable with higher cost-efficiency. Notably, higher capitalized banks are more profitable and cost-efficient by reducing risk. Finally, this study also provides some insightful policy suggestions to the stakeholders.

This study aims to determine the relation between the real sector and the financial sector in underdeveloped areas in Nusa Tenggara, Indonesia. To facilitate understanding of these linkages, researchers use the logic of credit channel mechanism of monetary policy, financial intermediation, as well as supply leading and demand following theories. The research variables include economic growth, inflation, liquidity, and NPL at the provincial level, with a data sample from 2008 to 2019. This research uses VAR/VECM as the analysis tools. The findings of the long-term analysis in East Nusa Tenggara show there is a phenomenon of cost-push inflation as well as the negative relation between inflation and economic growth. The impact of liquidity on inflation is positive, while the impact of economic growth on inflation is negative. Meanwhile, in West Nusa Tenggara, the impact of economic growth on inflation is positive. On the other hand, the impact of liquidity and NPL on inflation and economic growth is negative. In conclusion, generally, the economy in West Nusa Tenggara is better than the East Nusa Tenggara. The key to improving the economy of Nusa Tenggara is by improving its liquidity. This can be done by increasing the volume of public savings to increase bank credit capacity.

The soldering is widely used installing the electronic element on circuit board in the common electronic device. Since the flux which improves the liquidity of solder make the electronic and chemical performance worse, the circuit board need to wash clearly. At present however no-washing is required for the cost reduction, the chemical stability, and the protection of environment. In this research, the solder liquidity depending on the power density and the pulse width is comparatively analyzed by the diffusion area method for achieving the no-flux soldering.

Domestic construction industry is facing big difficulties by a worldwide financial crisis. Especially the deterioration of liquidity by the reject of banks for project financing and unsold housing project made a big problem on financing for the ongoing and new projects. To solve this, it is critical for construction companies. banking facilities and public organizations to cooperate and support each other. In this study, the methods which each part can do are investigated. Construction companies can do a price reduction, finance condition improvement for deposit and down payment, asset sale and cost reduction. And Public organizations can buy the assets of construction companies with proper price and ease the regulation to activate transactions of real estate. In the case of Banking facilities, they can support arrangement and liquidation of insolvent projects and so on.

한국 원화와 미 달러화 간 무위험 이자율 평형관계(covered interest parity)의 괴리는 2007~08년 글로벌 금융위기 시 큰 폭으로 증가하여 1,000bp(2008년 11월)를 상회한 바 있고, 최근에도 100bp를 기록하는 등 여전히 높은 수준을 유지하고 있다. 본고는 금융위기시 무위험 이자율 평형관계가 큰 폭으로 붕괴된 현상을 설명하기 위해 Garleanu and Pedersen(2011)의 마진을 기초로 한 자산가격결정모형(margin-based asset pricing model)을 상정하고 칼만 필터(Kalman filtering) 기법을 활용하여 실증분석을 시도하였다. 분석 결과, 무위험 이자율 평형관계의 괴리는 글로벌 달러 유동성 및 원화를 이용한 자금조달여건과 유의한 관계를 지니는 것으로 나타났다. 특히 유동성과 자금조달여건 간에 음의 상관관계가 존재하여 달러 유동성 위기 시 무위험 이자율 평형관계의 괴리가 추가적으로 증폭되는 유동성 악순환(liquidity spiral) 현상이 나타났음을 발견하였다. 또한 본고는 달러 유동성 공급 및 자금조달여건의 개선에도 불구하고, 여전히 차익거래 유인이 높은 것은 환율 변동성이 높은 수준에서 유지되고 있는 것과 관련이 있음을 보였다.

Due to recession in real estate market, interest of risk analysis is increasing. Feasibility study in the first stage takes a great role in a project. There are not objectified tools which are able to cope with uncertainty of project, and feasibility study based on selected method of determinism does not include liquidity of weight risk. Also, shortage of consideration for subjective and atypical external factors causes inappropriate results. Therefore, this study proposes feasibility study model focused on risk factor influences in construction cost and sales cost. Considering effective level of cost based on objective risk factors and probable weight of risk by this model, real workers are able to bring correct and scientific decisions better than former method based on selective analysis of real estate development.
