Although a large number of the existing literature have proved the importance of government implementation of childcare subsidies, few scholars have studied the implementation methods and how to implement childcare subsidies. In this paper, an optimal subsidy model based on the household unit is...

94% of Fortune 1000 firms experienced supply chain disruptions. The severe shortage of essential medical supplies caused by COVID-19 has severely hampered the healthcare supply chain (HCSC). This study explores the impact of supply chain resilience (SCR) on supply chain performance (SCP) and the...

Between June 1998 and March 2006, the price index of apartment housing in Seoul, Republic of Korea, more than doubled, while fundamentals such as gross domestic product, wage, and population increased by less than 35%. This study examines the role of a rational speculative bubble in this price...

This paper provides a new estimation method for the marginal expected shortfall (MES) based on multivariate extreme value theory. In contrast to previous studies, the method does not assume specific dependence structure among bank equity returns and is applicable to both large and small systems....

This paper defines asymptotic marginal expected shortfall (AMES) for banks within a financial system and provides corresponding estimation method based on multivariate extreme value theory. The estimation method does not assume a specific dependence structure among bank equity returns. Both...

Johansen and Sornette proposes that the crash has fundamentally an endogenous origin and exogenous shocks only serve as triggering factors. This endogenous force is shown in price as power law log-periodicity (PLLP) signature prior to a crash. We estimate the highly nonlinear model developed by...

Diba and Grossman (1988) and Hamilton and Whiteman (1985) recommended unit root tests for rational bubbles. They argued that if stock prices are not more explosive than dividends, then it can be concluded that rational bubbles are not present. Evans (1991) demonstrated that these tests will fail...
