This paper proposes an improved procedure for stochastic volatility model estimation with an application to Value-at-Risk (VaR) and Conditional Value-at-Risk (CVaR) estimation. This improved procedure is composed of the following instrumental components: Fourier transform method for volatility...

Tail risk is a classic topic in stressed portfolio optimization to treat unprecedented risks, while the traditional mean-variance approach may fail to perform well. This study proposes an innovative semiparametric method consisting of two modeling components: the nonparametric estimation and...

According to a Survey by the Society for Human Resource Management, 25% of human resource representatives interviewed in 1998 indicated that the companies they worked for ran credit checks on potential employees while the fraction increased to 43% in 2004. In this paper, we explore how such...

An important source of anthropogenic greenhouse gas (GHG) emissions is the air transport sector, which accounts for approximately 2% of global GHG emissions. Therefore, reducing GHG emissions from aircrafts has become a major challenge for transportation authorities worldwide. In recent years,...

The literature has pointed out that many decision makers could exhibit some degree of risk lovingness. Yet, it still lacks a suitable performance index which is consistent with the preferences of all of them, i.e., the preferred project has a higher score. To fulfill this need, our paper...

In this work we apply asymptotic analysis on compound options, American options, Asian options, and variance (or volatility) contracts in the context of stochastic volatility models. Singular perturbations are used mainly. A singular-regular perturbation is applied on Asian option problems....

Climate change has significant impacts on economy because the carbon emission, which plays an important role in climate risk, can rise the temperature with the rate never seen before leads to enormous uncertainty in the long term. This paper proposed a novel measure termed the carbon adjusted...

This thesis focuses on two topics in financial risk management: optimal hedge ratios and portfolio value-at-risk (VaR). The empirical analysis is based on the daily return series for the Taiwan stock market index and two associated futures contracts. The sample period for the daily data covers...

This paper examines the inflation-hedging behavior of the Hong Kong securitized real estate market between April 1986 and April 2007. The monthly series of the Hang Seng Property Index (HSPI) is selected as the proxy of the Hong Kong securitized real estate market due to its comprehensive...

This paper contributes to apply the time-varying symmetrized Joe-Clayton copula to study the dynamic linkage among possible safe haven assets in the international major markets over the past 34 years. We re-examine four major asset types (long-term government bond, equity index, oil, and gold)...
